It’s easy to notice that phones with AMOLED screens are more expensive than their IPS counterparts. What is the reason for the higher cost? Is it possible to immediately distinguish a display created using AMOLED technology from other types of screens? Why are such LCD panels rarely found outside the products of the South Korean company? The answers to all these questions are in this material.
Under the abbreviation AMOLED lies the decoding of “Active Matrix Organic Light-Emitting Diode”. This means that this matrix is built on the basis of organic light-emitting diodes, while it is active. Each pixel here lights up independently, as a result of which a separate backlit layer is not required - this reduces the thickness of the panel and also reduces power consumption.
Almost any AMOLED screen has the following structure:
- Upper layer - cathode;
- Below is organic layer with LEDs- there is no air gap;
- Posted even lower matrix of thin film transistors those involved in diode control;
- Followed by anode layer;
- It all lies on a substrate made of silicone, metal or some other material.
Structure of an AMOLED screen
The order of LED subpixels in AMOLED displays can be different. Samsung has long used PenTile - a checkerboard pattern (blue in the middle, two green on the sides, two red behind them). It is this position of the subpixels that has the most positive effect on power consumption.
PenTile - subpixel order used by Samsung
AMOLED or Super AMOLED: which is better?
Samsung smartphones use screens made using Super AMOLED technology. What are the main differences between such displays? Initially, the prefix “Super” meant the absence of an air gap - it was the South Korean company that managed to get rid of it in 2010. But now ordinary AMOLED screens manufactured by other companies can boast of this. Consequently, Super AMOLED is now a marketing feature of the South Korean manufacturer. That is, you can put an “equal” sign between AMOLED and Super AMOLED.
It should be noted that Samsung produces the largest number of AMOLED panels. South Koreans have already learned how to bend their creations in every possible way (doing this without a separate backlit layer is much easier). Rest assured, all smartphones with an AMOLED display, the edges of which are curved, are manufactured using South Korean matrices. Apple is going to open its own plant for the production of organic LED screens, but this will not happen earlier than 2020.
Main advantages of AMOLED panels
The physical properties of matrices consisting of organic light-emitting diodes are such that the screen can have tiny thickness. In particular, this is especially important for and, the physical dimensions of which should not be large.
But the most important advantage of any (including its AMOLED variations) is low power consumption. Each pixel of such a display glows independently. It turns out that the greatest energy consumption will be at the moment when the entire screen displays a flat White color. And if some areas need to display dark colors, they glow noticeably dimmer, which reduces battery consumption.
The darker the picture displayed on the display, the less energy is consumed.
High Contrast- another undoubted advantage of such screens. This is explained by the same ability of pixels to glow on their own. For example, hidden underneath is a substrate of LEDs that illuminate black colors as well. This doesn't happen here.
Differences in contrast are immediately noticeable
It is also due to this that the picture on the AMOLED screen clearly visible even under bright sunlight. IPS technology allows you to see something on the display on a clear day only by turning down the backlight brightness, which leads to a sharp increase in power consumption.
Phones with AMOLED display
As mentioned above, only Samsung is familiar with organic LEDs. But this does not mean that this manufacturer does not sell its screens to someone else. In particular, a 6-inch AMOLED panel is included in the popular smartphone OnePlus 5T. The resolution of this screen is 2160 x 1080 pixels, and the width of the side frames is kept to a minimum.
The screen, created on the basis of organic light-emitting diodes, has Meizu Pro 7. This device is much more compact - the diagonal of the display installed here is only 5.2 inches, and the resolution is 1920 x 1080 pixels. Distinctive feature The device is the presence of a second screen located on the rear panel, directly below. AMOLED technology was also used in its creation.
As for South Korean smartphones, there is no point in singling out specific models. For quite some time now, even relatively inexpensive devices produced by Samsung have had an AMOLED display. The only exceptions are ultra-budget models, sold for 4000-5000 rubles.
Conclusion
AMOLED screens are the future, that's for sure. Such displays do not have serious drawbacks, producing images with better color rendition and maximum viewing angles, while consuming a very small amount of electricity. The only problem is the higher cost of such panels. This results in a percentage of yield of suitable products that is far from a record. We can also mention that production rates are not the highest - alas, it is extremely difficult for Samsung alone to satisfy the demands of the smartphone market.
The question often arises on the Internet: which display is better? And as a rule, the debate most often flares up between AMOLED and IPS, so we will discuss these two technologies, which have become the most popular thanks to smartphones.
Let's talk first about IPS technology:
IPS technology (which stands for in-plane switching) was originally created for LCD displays, in order to eliminate some of the shortcomings due to which the characteristics of the then TFT displays were significantly inferior to conventional CRT monitors. The main disadvantages were the low response time, which made it impossible to play fast-paced games properly.
Second or more serious problem there was a very small viewing angle, which is why you had to look at the monitor at a strictly right angle, otherwise, when viewing from an angle, the colors were so distorted that you couldn’t understand anything, to the point that you could not understand anything at all.
The invention of IPS technology was a significant breakthrough, thanks to which response times were significantly reduced and viewing angles became acceptable. Now it was time to play games and work with images.
The main advantages of IPS technology:
- Good response time
- High-quality color rendition
- Good viewing angles
- Clear picture
Disadvantages of IPS technology:
- Requires more powerful lighting
- Consumes more energy
- Smartphones that use this technology are usually a little thicker, due to the backlight
Now a little about AMOLED:
AMOLED technology (which stands for Active Matrix Organic Light Emitting Diode) is an advanced OLED technology, which is organic compounds that emit light using electricity.
Thanks to AMOLED technology, it has become possible to produce thin smartphones, since it does not require backlighting, unlike IPS. At the same time, AMOLED has better contrast compared to LCD, as well as good viewing angles. But the main distinguishing feature of AMOLED from IPS is low energy consumption, since this technology allows you to activate only those pixels that are required at the moment, unlike IPS where all the pixels are lit while the screen is on.
The main advantages of AMOLED technology:
- No backlight required
- The element is thinner, allowing for the production of thinner smartphones
- No backlight saves energy
- Good contrast
Disadvantages of AMOLED technology:
- More complex and expensive production
- The picture is less clear than IPS
- Less bright picture than IPS
- Colors fade over time
As a conclusion, we can say that there is no winner here; rather, you need to choose from needs. If you need good color reproduction and this is extremely important to you, then take IPS; if it is important for you to have a longer battery life, choose a smartphone with an AMOLED display.
Why do you need a mobile version of the site? In complex modern world More and more advanced technologies are being created. Over the past decade, we have witnessed amazing growth in the development of mobile technology. Almost every week we see new gadgets appearing on the global market. Smartphones and tablets seem to be outpacing laptops and computers. More and more people use mobile devices in their lives. Entertainment, getting information or even running a business, all this can be done easily. Despite this obvious growth in mobile technology, there are still some webmasters who are too stubborn to convert their websites into mobile websites.
Website Building Technology News: The Benefits of Converting Your Website to a Mobile Optimized Website.In this article, let's start discussing a very hot topic that seems to irritate webmasters a lot, why we should convert an existing website into a mobile website. The first obvious reason is that most websites that have not been converted to mobile sites will not display correctly on mobile devices. You can easily lose repeat visitors and sales in this situation. For example, if a mobile user is looking for something to buy on your website, but finds out that your site structure is loading too slowly, he will certainly leave to look for the required item on other mobile websites.
Mobile sites are the best
Why does a website need a mobile version? Moreover, mobile websites also rank higher in search engines. It is clear that in classic search engine optimization (SEO), things have already gone too far. But with mobile SEO, it's just the beginning! The largest search engine in the world, Google will, in fact, first display results that are optimized for mobile users. Here's how you can get the means to achieve your goals and beat the competition!
With mobile websites, you can be there for your visitors all the time. Most mobile phone users are on the move and search for information on the go. If you display a phone number on your mobile site, your visitor can call you directly from their mobile device. For example, if you are a restaurant owner, this hungry user appears to be passing through your site. He can call the restaurant directly from his mobile phone and inquire about the food, location or any other information he needs! That's what the mobile version of the site is for.
Now you can see how great it can be to convert your existing website into a website for mobile devices (phones, smartphones, phablets, tablets)!
Before you finish, consider some numbers. The world population is 6.7 billion people. Of these, five billion are mobile users. If that's not enough to convince you to convert your site to a mobile website version, here's another fact; an incredible 80 percent of these mobile users access the Internet using their mobile devices every day! That's four billion users every day. It is undoubtedly clear that the mobile industry is moving very quickly. Over the next two years, Mobile Internet will overtake the natural website industry. So, friends, don't forget to take care of your mobile website today!
Electronics manufacturer Cooler Master has a range of hardware products such as keyboards, power supplies, headsets, computer (PC) cases, mice and, of course, coolers. Each of its products has been specifically designed based on community feedback. Including hybrid keyboards. Cooler Master even had a Kickstarter project for an analog keyboard with pressure-sensitive keys called the ContolPad. With that said, let's take a closer look at what can make the new Cooler Master SK621 keyboard special for the user.
Keyboard news today: Cooler Master SK621 review - a mechanical wireless keyboard with a separate wired connection option.The first thing that is noticeable during the review is the ability to conveniently pair the wireless keyboard with three different devices. Connecting your device is as simple as holding the function button and Z, X or C. This feature makes it very easy to switch from using your phone to your computer. Turning on the Cooler Master SK621 keyboard is also easy. Either connect it via a USB Type-C cable, or on the left side activate the very simple switch for wireless mode.
Technical characteristics of the Cooler Master SK621 wireless keyboard:
You can map a wide variety of colors (shades) to any key, customize lighting modes, or customize macros using the Cooler Master software.
How does a wireless keyboard work?
When using the SK621 for the first time, it is recommended to connect to your computer via USB Type-C and install the Cooler Master Portal. This will allow you to control the different lighting effects and settings of the wireless keyboard. It is possible to create preset profiles, which makes it easier to switch between profiles when using elements. You can also adjust the lighting effects using the controls, but the above mentioned portal is more user friendly. The wireless keyboard setup is very easy to use and has many combinations. There are options - adjusting the speed, direction and brightness of the keyboard backlight effects.
Macros can also be programmed. It’s also worth adding that all functions such as RGB lighting, macros and controls are also available when using the SK621 via a Bluetooth connection. The wireless keyboard's battery life is also impressive. It may take a couple of full business days before the light turns red, indicating that the battery is low. Charging the SK621 wireless keyboard is also easy. Just connect your keyboard via USB Type-C. The keyboard can still be used as a wired keyboard as long as the cable charges the keyboard's battery.
The keyboard's body is crafted from polished aluminum, making it lightweight, durable, and provides a premium appearance. There's also a nice sleek aluminum edge accent that adds a touch of elegance. The keys are made of plastic and don't have much texture.
Low-profile Cherry MX keys are quiet enough for office use. The key switches are incredibly sensitive and using the Cooler Master SK621 Wireless Keyboard takes some practice. This is because the keys register key presses to within a millimeter or less.
The SK621 hybrid keyboard is designed to be compact and quite portable. A nice addition is the velvet bag. It's definitely made for gaming thanks to its Cherry MX keys, but it's easy to use for work.
The Cooler Master SK621 does everything it's designed to do. However, the keys are great for gaming but are too sensitive for typing. Plastic keys are also prone to oil stains on your fingers, so eating while gaming can be difficult. Perhaps if the keys had some kind of oil-resistant coating or more texture, the oil marks wouldn't be as pronounced.
Features of SK621 Wireless Keyboard:
Brushed aluminum body design;
Featuring a flat, brushed aluminum keyboard top, floating keycaps, and a slim, minimalist body design.
Colored keyboard backlight Cooler Master (RGB LEDs);
Individually customizable LED key backlighting and surrounding LED ring.

ETH Zurich has unveiled details of "Concrete Choreography", an installation that recently opened in Riom, Switzerland. The innovative installation features the first robotically constructed 3D printed concrete stage, consisting of formless columns 3D printed to full height in 2.5 hours. The process is expected to significantly improve the efficiency of concrete structures while achieving the fabrication of complex material components and construction robots.
3D printing news: ETH Zurich creates concrete columns using a special 3D concrete printer.In Riom, Switzerland, the Origen festival features nine 2.7-meter-high columns. Each column is 3D printed concrete. The new columns were individually designed using custom software and manufactured using a concrete printer, a new automated concrete 3D printing process developed by the ETH Zurich team with support from NCCR DFAB.
3D concrete printing like this
MSc Digital Fabrication and Architecture students explore the unique capabilities of multi-layer extrusion printing, demonstrating the potential of computer-aided design and digital fabrication for the future of concrete construction. Perhaps in the construction industry, this process will become more environmentally friendly in the future if they develop new eco-friendly concrete for 3D printing.
Video review of 3D concrete printing: Concrete choreography.
This is how easy and fast 3D concrete printing works.
3D printing of houses and buildings made of concrete is a prospect for construction.
Hollow concrete structures are printed for the strategic use of materials, resulting in a more sustainable approach to a specific architecture. Additionally, the calculated material structure and surface textures are an example of the versatility and significant aesthetic potential of 3D concrete printing when used in large-scale structures.
The new review will be about printing on a 3D printer with metal.
It is worth noting that there is technology to carry out 3D printing with metal. This is also a promising direction for construction, but for this, other materials are used (for example, powder), programs and other types of printers (which we will talk about soon).
What color is your mobile phone? Is it black, red, white, gold or blue? Most likely, the back of your phone has some kind of solid color option that you will find in a coloring book for beginners. It has taken too long for most phone manufacturers to realize that phone colors actually matter to consumers, and it is only recently that they have started giving mobile phones not just a rarely used color, but fancy shades like coral red or canary green.
Honor News: With new 3D holographic color phones from Honor, it's possible to add a little new color to life.It's no surprise that most people don't mind hiding the backs of their phones behind an opaque plastic case. In cases, the user can choose a suitable color for the phone case to give the mobile a little personality. But China's new Honor 20 Pro and Honor 20 series phones are the world's first smartphones with 3D dynamic holographic design, and their reflective appearance could become a new industry standard.
"Always better" is the company's motto. Perhaps this motto suggests that she refuses to follow the industry standard by simply experimenting with layers of paint with each new phone model.
Color 3D holography for the phone case.
In order for the phone body to achieve a shimmering optical illusion, the manufacturer Honor designed its Honor 20 model with a deep layer containing millions of shimmering microscopic prisms, and on top of this a so-called 3D curved glass layer is placed. The combination of these technologies causes the light to "play and dance" on the back of the phone as the user turns it in different directions.
Two colors for the Honor 20 phone can be found under these dynamic layers, Midnight Black and Sapphire Blue. Unlike the newfangled phrases for some phone colors, Honor mobile has color gradients for phones that actually evoke the effect of a shimmering night sky or a shimmering jewel.
While the color options sound exciting, you can go even further with the Chinese Honor 20 Pro phone. This upgraded model features the signature "Triple 3D Mesh" containing three layers. Instead of just painting the back of the phone itself, this time a layer of body color sits between the outer 3D layer and the inner depth layer. According to the phone maker, this makes color shifting effects much more dynamic.
The Honor 20 Pro mobile phone is actively sold in two colors such as Phantom Black and Phantom Blue. Although the names of these phone colors are not so metaphorical, do not think that their rear panels are less dynamic.
Honor's obsession with choice the right colors This may seem overly dramatic, but in the UK, for example, a survey of hundreds of Britons found that forty-nine percent of them consider color when choosing a phone to buy.
Why is a phone with a changing color scheme being sold?
What is a phone for? Choosing a mobile phone, as Honor designer Jun-Soo Kim puts it, is “Extending human life.” Essentially, Honor is saying that customer identity cannot be captured in one unchanging color.
The history of the creation of Honor color phones.
The Honor 20 demonstrates the natural evolution of the company's experiments with dynamic color in phone design (irridescent colors). The Honor 8 model started the trend of multi-layer back wall type 2.5D, which creates a 3D lattice effect. Then the Honor 9 version turned into a phone with a curved 3D glass, echoes of which can already be found in the Honor 20 model. Well, last year, the Honor 10 model was equipped with an Aurora rear glass that reflected colors from all sides.
What is the screen like on an Honor phone?
Honor's design innovations don't stop at the color of the phone's body. It's worth paying attention to the placement of the Honor 20's camera. Instead of trimming the screen to make room for the "selfie" camera. The phone maker has cut a 4.5mm hole in the top left corner of the screen, thereby leaving more screen space for the user's needs.
Camera with artificial intelligence or AI camera in your phone.
According to the description of the phone, it is worth noting that on the back of the device, the Honor 20 AI camera has four lenses and is located so as to leave more space for a battery with more memory. But most importantly, the result is a 48-megapixel camera that uses the Kirin 980 AI microchip to take DSLR-quality photos and enhance photos.
Summary of Honor phone color.
Bottom line, phone descriptions, technical compatibility and cutting-edge hardware innovations are what usually attract attention to Chinese Honor phones. But in this case, the technology is almost overshadowed by the uniquely colored body design, which may make some users reluctant to go back to simple 2D phone body colors in the future.
Rumors continue to arise about the release of the Google Pixel 4 mobile phone. New set information or predictions comes from a leaked image on the Internet (3D rendering of colored cases), which is believed to refer to the Google Pixel 4. It is not uncommon for users following the topic of new products to overlook such images. Meanwhile, for some analysts, the new picture helps make a few assumptions about more than just the color of the phone.
A new unofficial image of the Google Pixel 4 is sparking rumors about color options for the mobile phone's body.
While another image of the phone body itself doesn't seem to show more than what was previously discussed online, the model seen in the background of the photo raises eyebrows due to its color. That mobile phone has a shade of purple that the Pixel model didn't have before.
Elsewhere, there have been other leaks of the same Google Pixel 4 with "three phones" (variants) stacked in a row. There are white and black colors, plus the third has a bluish tint, which some call mint green. Would you like to buy a blue phone? Probably the name of the phone colors will still be updated.
Whichever phone color leak is true or false, it's safe to assume that this year new Google The Pixel 4 will definitely have an additional color. What's even more interesting is that in the image, the physical buttons on the sides of the phones contrast with the color of the body. You can see white, blue and yellow buttons which give the phone a fun look.
For some strange reason, all the images and leaks seen so far have only shown the rear panel of the Google Pixel 4 smartphone. As reported by various sources, Google allegedly shared a render of the phone, and there was also a part where the square camera bump was featured. The dual camera unit was visible.
The leaked photos in question, including an image along with the cases, show the back panel in different colors and the camera module. What do you think is the best phone color?
About specifications Google Pixel 4:
Obviously, the idea of a fingerprint scanner is not leaving fans alone. Some people want the phone to either have Face ID to unlock the phone, or an in-display fingerprint scanner, or both.
Some other aspects and specifications, such as the dimensions of the phones and the overall thickness being 8.2 millimeters higher compared to the 7.9 mm seen in the Google Pixel 3 and Pixel 3 XL, can be taken as close to reality.
There is speculation that the Google Pixel 4 and Pixel 4 XL versions of the phone may look more like the "Apple iPhone 11" variant that is slated to launch in a couple of months. When, exactly? Technology company Google has yet to announce an official release date for the Pixel 4, but various sources are hinting at a new phone launching later in the year.
Have you ever wondered why you need the latest model phone? We'll tell you more about this soon, so stay tuned for news about new smartphones from Google.
The robot set a world record for solving a Rubik's Cube. This robot was developed by Massachusetts Institute of Technology (MIT) students Jared Di Carlo and Ben Katz in a student laboratory. For comparison, the fastest human record is held by Australian Felix Zemdegs, who solved the Rubik's Cube in just 4.22 seconds in 2018. By the way, the original size Rubik's Cube has 43 quintillion possible combinations for one solution. Watch the video of the record-breaking robot below.
Robotics news: MIT's nimble Robot solves a Rubik's Cube in a world record time of 0.38 seconds.Many people have a special place in their hearts for the Rubik's Cube. This is a good workout for the intellect. Many people loved or still love to play with this ingenious toy, and over the years there have been many competitions, challenges and variations to solve the Rubik's Cube.
The popularity of the Rubik's Cube can be attributed to the simplicity of its design combined with the mind-boggling complexity of the puzzle.
New record for solving a Rubik's Cube 3x3x3.
Engineers and hobbyists have been using robots to solve Rubik's Cubes for years. 10 seconds used to be considered a quick assembly, but by today's digital age standards, that's a time that makes you smile.
It was only a matter of time before engineers and roboticists began to tackle the challenge of creating a new robot. Back in 2016, the robot set a new record for solving a Rubik's Cube in 0.637 seconds. But for some enthusiasts, that time wasn't fast enough.
Just recently, two MIT students, Jared Di Carlo (a third-year electrical engineering and computer science student) and Ben Katz (a mechanical engineering graduate student), thought they could build a faster robot that could solve a 3D combination puzzle.
They watched videos of previous robots, and noticed that the robots' motors were not the fastest that could be used to solve the problem. So they thought they could do better with better engines and controls.
How a robot solves a Rubik's Cube
Students installed an electronically controlled motor that powers each face of the Rubik's Cube. Using a pair of web cameras pointed at the cube, special software determines the initial state of each side of the cube (which colors are on which side of the cube at a given time). Then, based on the information received, using existing software for solving the Rubik's Cube, the robot solves the puzzles using an algorithm.
What is the result of the work? Their robot solved a Rubik's Cube in 0.38 seconds! It is safe to say that no person is physically capable of breaking the record for this speed. We can add another achievement to the list of robots surpassing humans.
There is a man who holds the fastest world record for manual assembly, his name is Felix Zemdegs. He was able to solve the Rubik's Cube in 4.22 seconds. The skills and talents that robots are replacing are vast and varied, to say the least. Not to mention that robots can still surprise. Next is a video demonstration of the robot; it’s better not to blink while watching.
Video review of assembling a Rubik's Cube in 0.38 seconds:
That's it, hardware hackers Ben Katz and Jared Di Carlo broke the previous record for robotically solving a Rubik's Cube. Their robot solved the puzzle 40 percent faster than the previous record.
Details about the record-breaking robot
The robotic device is assembled from motors from the Kollmorgen ServoDisc U9 series, PlayStation Eye cameras (for scanning the cube) and, of course, a Rubik's Cube was needed. According to the robot's creators, "The entire software process takes about 45 milliseconds. Most of the time is spent waiting for the webcam driver and determining the colors on the sides of the Rubik's Cube."
Facebook Inc. Artificial Intelligence Research Group. introduced a new robotics platform called PyRobot. This platform (framework) was developed jointly with researchers from Carnegie Mellon University. PyRobot aims to help AI researchers and students integrate deep learning models built using the PyTorch platform (a machine learning library for the Python programming language) with the robots they create. The basic idea is that they can create their robots more easily by using artificial intelligence skills such as natural language processing.
News from the world of robots with AI (AI): Facebook introduces a platform for robotics PyRobot is an open source framework for controlling robots.Facebook said it wants to promote long-term robotics research to help develop embedded artificial intelligence systems that can learn more efficiently by interacting with the physical world.
Previously, to stimulate the production of artificial intelligence models, the company introduced PyTorch Hub.
What is PyRobot today
PyRobot is a lightweight, high-level interface that provides hardware-independent APIs for robotic manipulation and navigation. The PyRobot repository also contains a low-level stack for LoCoBot, a low-cost mobile manipulator hardware platform (robot assembly toolkit). Now artificial intelligence and machine learning are becoming more accessible to those new to robotics.
Research supervisor Abinav Gupta and Saurabh Gupta, as a research fellow at Facebook, explained in a blog post that: PyRobot is a lightweight, high-level interface on top of the robot's operating system. It provides a consistent set of hardware-independent mid-level APIs (application programming interfaces) for controlling a variety of robots. PyRobot abstracts away the details of low-level controllers and interprocess communication, so machine learning specialists and others can simply focus on building high-level AI (artificial intelligence) robotics applications.
Facebook's source also says PyRobot has dozens of potential applications, such as helping researchers share data and set benchmarks and build on each other's work. The company solicited proposals from the broader AI research community on how to democratize robotics using LoCoBot and PyRobot, which are hardware specifications and tools for building low-cost robots.
PyRobot works by using APIs to abstract the functions that robots need to use. Perform tasks such as kinematics, path planning, position, speed and torque control for joints, and visual simultaneous localization and mapping. PyRobot comes with a number of pre-trained deep learning models that allow robots to navigate, grasp objects, and more.
This means developers can program their robots using just a few lines of Python code, Facebook says.
Facebook researchers also say that: The cost of hardware and the complexity of specialized software limit the scope of robotics research. With lower barriers to entry, researchers can, for example, build multiple robots that collect data and learn in parallel. Providing a common platform for various equipment. PyRobot will lead to the development of benchmarks in robotics, similar to other areas in AI, and will quantify the pace of progress in AI robotics.
Like Amazon's RoboMaker, PyRobot runs as an interface on top of the robot operating system (ROS), extending the infrastructure. In May, technology company Microsoft released a set of robotics tools with a limited preview, and last year integrated the ROS platform into Windows 10.
The famous analyst and author of Apple smartphone forecasts, Ming-Chi Kuo, can certainly be the most reliable source of leaks and information about Apple products. And today he released a new research report, obtained by Mac Rumors, where he mentions the future of the iPhone and when we can expect Apple to finally switch to 5G (fifth generation mobile communications) smartphones.
Rumors and technology news: Analyst Ming-Chi Kuo predicts Apple will release 5G iPhone in 2020Back when Apple was still planning to use Intel modems in its iPhones, there were rumors that the "iPhone 2020" phone model would be the first to receive 5G support. However, the Apple company has since switched from its modem supplier to Qualcomm. For which they had to settle a long patent dispute with an American chip manufacturer, pay at least 4.5 billion dollars and not use Intel modems. Intel may even have shut down its 5G plans after this news.
According to a note by analyst Kuo Ming-Chi, the development of a new version of the iPhone 5G mobile phone is proceeding exactly on schedule. Allegedly, we will see Apple announce the release of the 5G iPhone in 2020. Kuo's note also mentions that both the 5.4-inch iPhone model and the 6.7-inch iPhone model will have a 5G modem. A hint is given of some kind of update to the iPhone XS and iPhone XS Max smartphones.
Ming-Chi Kuo also said that all three iPhone models in 2020 will come in multiple colors and feature an OLED screen, as opposed to the LCD screen on the current iPhone XR. However, we'll probably still get an iPhone XR upgrade with an LCD display this year, so if an OLED screen in a mobile is too much of a deal for you, maybe wait a year.
5G iPhone competitors:
Currently our best Android competitors are the following 5G phones:
1) Xiaomi Mi Mix 3 5G (128 GB memory, 6 GB RAM and battery with fast charging);
2) OPPO Reno 5G (innovative design, affordable price, powerful camera);
3) LG V50 ThinQ (screen 1440 by 3120 pixels, memory expansion up to 1 TB, 4000 mAh battery);
4) OnePlus 7 Pro 5G (frameless AMOLED screen has no notches or holes);
5) ZTE Axon 10 Pro 5G (48 megapixel camera, Snapdragon 855 chip).
New articles will contain a unique video review of 5G phones with prices.
Global sales of 5G phones.
Global deliveries to stores of mobile phones supporting 5G technology (this is the fifth generation of fast mobile communications) may be higher than market analysts' expectations. It's worth noting that some mobile market observers believe such shipments are likely to reach 150 to 200 million units, or more than a dozen percent of global 5G phone shipments next year.
Facebook has unveiled a new project called Calibra, a digital wallet for storing and sending Libra “crypto coins.”Billions of people are expected to be able to make payments using cryptocurrency from social media giant Facebook through their mobile apps. The social network Facebook plans to officially launch a new cryptocurrency project, Libra, in 2020. Libra is a new type of digital money that is intended for billions of people using mobile applications and the social network.
The popular social network Facebook has more news for the world of cryptocurrency.
That a new digital wallet would be created that would allow Facebook app users to store and exchange cryptocurrency. Facebook is creating a new subsidiary, Calibra.
Why is Facebook betting on a cryptocurrency called Libra? Perhaps a high goal the latest development, go beyond social networks.
Digital wallets for storing, sending and spending Libra cryptocurrency will be connected to messaging platforms.
Initially, the cryptocurrency will be available in the Facebook Messenger / WhatsApp application, and of course in separate applications for iOS or Android.
Facebook said in a press release that: “Initially, Calibra will make it easy and instant to send Libra at a low cost to virtually anyone with a smartphone.”
It also says that: “Over time, additional services will be offered to businesses and people, such as buying a cup of coffee with a scanned code, paying a bill with the touch of a button, traveling on public transport without having to carry cash.”
Security of the Facebook cryptocurrency wallet.
To improve the security of the new cryptocurrency, it will use similar verification and fraud protection features that are already in use credit cards, banks. Facebook's cryptocurrency service will have user support. And in case someone else gains access to the user account, compensation for lost assets is promised.
Cryptocurrency coins will be stored by users in a digital wallet. But the world of cryptocurrency itself is not always stable! Time will tell if Facebook's own digital money will help people save money by sending and spending it as easily as sending text messages.
The cryptocurrency will be managed by the founding members: Facebook, more than two dozen different organizations and a separate Swiss foundation.
Why Libra?
What does the word Libra mean?
Former PayPal executive David Marcus, who heads the Facebook project, said something like this: "The choice of the name Libra (Libra) was inspired by several reasons, namely the French word for Liberty, the Roman measurement of weight, the astrological sign of justice."

Technology and design news: Insanely beautiful iPhone 11 concept with innovative, colorful, curved screen.Technology giant Apple will release iPhone 11 this coming September. If all sorts of rumors turn out to be true, then the multimedia phone could have the same design as the last two generations of the phone. Regarding the final design of the iPhone 11, we are ready to accept what Apple designers come up with. But, we can't stop imagining what could be if technology allowed us to create any design for the iPhone 11. And that's exactly what some very talented designers are doing. This time around, there's a beautiful concept for the iPhone 11 that ditches all the buttons in favor of an immersive curved phone screen.
The implementation of such a design results in an iPhone with a beautiful glowing strip that stretches along the entire mobile phone and replaces the physical volume rocker buttons and the power button. Using this design philosophy allows you to get an iPhone with on-screen icons on the side.
While it may be a good looking phone, there is absolutely no chance of the concept becoming a reality. In addition, protecting such a phone with a case seems impossible, since by covering the screen space the case will take away some of its basic functions. Imagine that if a phone like this were accidentally dropped on the ground, the cost of repairing a curved screen would be higher for the user than with a classic screen option.
We hope the new iPhone 11 will have a bright screen under the sun.
The 2019 iPhone 11 lineup is expected to feature three models, just like last year. There will probably be two OLED phones and one with an LCD screen. The iPhone 11 and 11 Max models may have a variety of OLED screens, and also have screen sizes of 5.8 and 6.5 inches, respectively. Perhaps the iPhone 11R model will be equipped with an LCD display to reduce the price to a minimum.
It is also expected that the new versions of the iPhone 11 and 11 Max will have a triple camera configuration, while the iPhone 11R version is expected to be equipped with a dual camera. Essentially, this means that all three mobile phones could come with an additional camera on the back.
The front of the iPhone 11 lineup is expected to remain the same and there will be no difference in the size of the notch. However, recent reports claim that there may be improved face identification that will be able to authenticate a user at some extreme angles.
Video review of the iPhone 11 concept with an innovative, curved screen on the side:
According to the creator of this video, the new bezel-less iPhone 11 could have the following specifications:
6.4-inch full-screen display;
- Hidden front 13MP camera;
- Four cameras, 8K @ 120 FPS;
- New Apple operating system, iOS 13;
- Apple A13 Bionic mobile chip (up to eight times faster than the A12 Bionic chip).
Do you want to know what the “wow effect” is? Pick up at least one Samsung smartphone with an AMOLED display! And, if this is the “WOW!” you won’t be able to escape, consider that the guys from Samsung haven’t earned their fees. So bright, so colorful, so attractive! My hands are tempted to scroll through websites, look through the gallery, and browse through applications and settings.
Is the almost branded Samsung display so good and what about IPS screens? Of course, they don’t make you wildly delighted at first glance, but the technology will be better than AMOLED in some ways.
Yes, getting to know the latest Samsung gadgets is infuriating. And if you haven’t yet turned into a zombie and haven’t gone to the checkout to lay out your hard-earned money for a bright and contrasting image of an armful of balloons on the mainscreen, all is not lost and there is something to talk about with you.
In fact, the selling brightness and contrast of AMOLED displays is not so ideal: the beautiful wrapper hides a couple of significant troubles.
What is AMOLED? AMOLED -Active Matrix Organic Light-Emitting Diode, i.e. active matrix on organic light-emitting diodes. The light emitters in AMOLED displays are organic light-emitting diodes, which are controlled using an active matrix of thin-film transistors (TFT).
Why AMOLED?
Firstly, AMOLED screens have extremely high contrast, which IPS cannot boast of.
Secondly, thanks to image transmission technology different from IPS, an AMOLED display can show absolutely black color. Why?
IPS screens are usually backlit from all sides, and the pixels in AMOLED light up on their own, so the manufacturer was able to perfect the transmission of black in them: when displaying images on such screens, the pixels that transmit black color will not light up. In IPS screens, the entire picture is always backlit, so it is impossible to achieve deep blacks on them. The contrast of AMOLED displays thus becomes almost infinite.
The second advantage also leads to a third, albeit very controversial one: AMOLED, due to selective backlighting of pixels, also claims to be selectively economical in energy consumption. In other words: in dark scenes, the AMOLED screen wastes nothing at all! But, on the other hand, when it comes to displaying a bright picture, the efficiency of AMOLED technology can be questioned.
The fourth plus(s): the touch response time of AMOLED displays is less than that of IPS. Those. Changing pictures on the screen should happen at lightning speed. In truth, AMOLEDs do work faster in this regard, but the speed difference is hardly perceptible.
By the way, in the Samsung Galaxy S4 the notorious reaction speed even became a problem: when changing an image (even when simply moving from menu to menu), “trails” from the previous image stretch across the screen. The manufacturer prefers not to answer questions about what to do about it and how to continue living. Apparently, it's all about new technology Super AMOLED. It’s not that it would be a big nuisance, but it would be wrong to remain silent.
Fifth advantage: AMOLED is thinner, which means devices with such a display are lighter. The difference in the thickness of AMOLED and IPS is explained by the same backlight technology: the pixels in IPS still need to be backlit, and for backlighting you need space in the case.
But, in fact, we’re talking about a maximum of a hundred grams, so if you don’t have a thing for ultra-thin gadgets, you shouldn’t consider the fifth point a significant advantage either.
Saturated color scheme AMOLED screens can be appreciated at least in the Samsung Galaxy S3 and Samsung Galaxy S4, as well as in the Galaxy Nexus.
What is IPS? IPS is a type of matrix of LCD monitors, the name of which stands for In-Plane Switching. The technology is so named because of the way the crystals are placed in the panel. IPS is distinguished by the fact that the crystals are located in the same plane parallel to the surface of the panel. This made it possible to obtain maximum viewing angles (up to 178 degrees).
Why IPS?
Firstly, despite the contrast of AMOLED, IPS screens convey colors much more accurately. If on AMOLED they can be turned up to completely unnatural shades, then IPS will give bright colors only when the real picture suggests it.
It is also possible to set natural colors on AMOLED, but not without difficulty and special access to the software settings. But with software settings, the AMOLED matrix can compete with any modern technology. Well, almost anyone.
Secondly, IPS screens provide perfect white, which cannot be achieved on AMOLED. This is not a small thing, as it may seem. Take, for example, the sad stories about the transmission of blue, yellow and pink shades of white by “amoles”.
On the one hand, a custom software setting can put everything in place, but it still won’t give you a good white AMOLED: if the color rendition can still be customized, then whitening the device’s display will cost you a lot of effort.
Big plus number three: maintaining color reproduction in IPS is possible even with an acute viewing angle. Colors on high-quality IPS hardly degrade, no matter how you look at the screen.
Whoever says that this is all nitpicking, try getting together with a group of at least three people to watch a film or photographs: the person sitting in the center will see the picture without distortion, but those sitting to the right and left of him will have yellowish and blue colors, respectively.
IPS practically does not produce angular distortion, and AMOLED, alas, does not indulge in such characteristics. Just remember the Sony Xperia Z, the screen of which rather spoiled the impressions of what was, in principle, a good device: a faded screen with low contrast and poor viewing angles.
AMOLED often suffers from the fact that it shifts natural color reproduction to the cold side. A non-standard layout of subpixels, moreover, leads to the image appearing in different colors: depending on the angle at which you look at the screen, the picture may turn red or green.
Let us recall that most often one pixel is formed by three subpixels: red, green and blue (the so-called RGB layout).
AMOLED works on a different principle. These screens use a method of constructing an image in which the subpixels are arranged in a special way. For clarity, see the picture below. According to the standard, a pixel is formed by three RGB subpixels, and in AMOLED displays, subpixels can be arranged as RG-BG, and not as RGB-RGB in the generally accepted version. This technology is called PenTile.
The photo below shows the standard RGB layout and the previous generation PenTile.
Subpixels of different colors can glow with different strengths, which is why on AMOLED the picture looks less detailed and clear (these flaws most often appear along the contours of the depicted objects).
There is no such looseness in IPS displays; accordingly, IPS provide better sharpness and detail. In fact, you don’t need to have superpowers to notice the pixelation of a picture. Unlike IPS, the structure of the AMOLED matrix can be noticed by, say, any myopic user who decides to read a detective story before going to bed. This is the fourth plus.
Again, because AMOLED illuminates each individual subpixel; there is a possibility of burnout of these organic LEDs (example in the photo, see below). The guaranteed service life of such a screen is at least 6 years, but even after a year of using the device, changes in brightness and color rendition can still be noticed.
IPS screens offer much higher maximum brightness. Hence: the readability of any image, accordingly, becomes better. AMOLED screens begin to “go dark” when exposed to direct sunlight: the brightness of such a screen is not enough to highlight the picture in the sun.
In 2016, competition between AMOLED and IPS matrices continues. Ordinary users often have a question: “Which screen is better?” Let's try to understand the advantages and disadvantages of various displays and make a choice.
Pros and cons of AMOLED
For many years now, the main disadvantage of AMOLED screens has been considered PenTile - a specific arrangement of matrix subpixels, leading to loose lines and fonts, distorting colors and reducing the actual display resolution. Yes, you heard right, if you buy a smartphone with an HD AMOLED display, you will actually get a lower resolution.
However, modern devices have more than sufficient FullHD or 4K screens, and you can only see the reduced resolution or the PenTile itself if you have excellent eyesight and specifically look at the image. When using a smartphone, such shortcomings are simply invisible.
AMOLED also has difficulties with white color, distorting it and turning it into gray or yellow, however, PenTile RGBW has already appeared in the Motorola Atrix 4G, which has additional white subpixels for correct color reproduction.
Users who use a smartphone for a long time should pay attention to AMOLED burn-in. Depending on the model and frequency of use, after a while the display loses its former brightness, begins to turn yellow, and status bars, on-screen buttons and other constantly-on interface elements appear in the white areas.
But such screens manage to save batteries, convey excellent black color, contrast and have a low response time without any cables, which is perfect for fans of games and movies.
Pros and cons of IPS
Perhaps the main problem of modern smartphones is the rapid discharge of batteries, and IPS screens will happily help the processor quickly suck all the juice out of the battery, leaving you without a connection. This is due to the additional backlight layer, which also thickens the entire display module, resulting in a large gadget size and an unimpressive black color.
By the way, you will have to overpay for all these delights, because they are noticeably more expensive to produce than others.
But IPS matrices will delight the owner with accurate color reproduction, honest resolution, durability and true pure white color.
SUPER AMOLED or IPS which is better?
So, we have found out the pros and cons of the technologies, all that remains is to answer the question: “which display is better IPS or SUPER AMOLED?”
If you are a fan of bright, rich colors, watching dynamic movies and games, then your choice is SUPER AMOLED.
If you want to see the most accurate color reproduction, durability and are fond of web surfing or mobile photography, then IPS is more suitable.
In practice, the differences between matrices are not as great as the manufacturers' settings. You shouldn’t choose a smartphone based only on the screen type, since it may have eye-catching colors or contrast specified by the manufacturer; moreover, in 2016, both technologies are able to provide comfort to the user and not disappoint him.
