Super Amoled technology is a new way of manufacturing TV matrices, which was developed by Samsung. The term got widespread due to the advertising campaigns of the brand, which is actively promoting its technique with this technology of creation. Other manufacturers prefer LCD IPS matrices more often. Let’s take a closer look at what an Amoled display is, and whether it is really better than classic options from other brands.
AMOLED vs Super AMOLED Technology features
In 2010, Samsung developed a new matrix based on LEDs. There is no air gap under the Touch Screen in it. The touch layer is located directly on the display. And due to this, the indicators of brightness and contrast have improved. At the same time, energy consumption has decreased. New TVs by the type of screen began to resemble modern smartphones. Additionally, this technology eliminated the risk of dust getting on the matrix and the appearance of glare.
Despite the fact that this technology has become widespread and is used to create not only TVs, but also mobile touchscreen phones, only Samsung continued to use the term Amoled.
features of Super Amoled
Super displays are different from classic Amoled matrices. They are built on a completely different type in contrast to LCD TV. Super Amoled has mini LEDs instead of liquid crystals. They have the same filters as LCD crystals, but they emit light themselves. Their brightness changes depending on the power of the supplied current using the method of pulse width modulation (PWM).
The new approach eliminated auxiliary illumination and specularly reflective substrates. As a result, the thickness of the matrix became smaller, as did the power consumption.
Let us remind you that LCD or LCD TVs are powered by liquid crystals, diode backlighting and a special mirror substrate. The light emitter is located behind the crystals. It transmits it through a liquid that partially absorbs light. Depending on the position and number of crystals, the brightness becomes more or less. In this case, the radiation is only in three colors: red, green, blue. Their combination changes the shades of the picture on the screen.
It turns out that Super Amoled displays give the best image quality, contrast and brightness indicators. Due to the absence of an air cushion and the use of LEDs instead of liquid crystals.
Advantages of super amoled
Super Amoled displays outperformed the LCD options. They also require careful handling, but have the following advantages:
- Small screen thickness. The elimination of the substrate, diffuse and light-absorbing filters from the design made the screens thinner than their LED counterparts. This is also facilitated by the presence of a sensor installed without, albeit a small, but air gap.
- Reduced energy consumption. An important criterion in modern conditions of rising prices for housing and communal services. This was achieved due to LEDs, which themselves adjust the brightness, rather than the use of individual pixels and light sources.
- Pure and rich black. In liquid crystal screens, a black tint was obtained by rotating the position of the liquid crystals so as not to let the white light from the backlight pass through. But part of the light from the radiation source still leaked out. And in the end, instead of pure black, it turned out to be dark gray, blue or brown. In Amoled technology, this has been completely avoided. The pixel simply turns off when dimming is needed. There is no brightness in black, so this option with the shutdown became optimal.
- Adjustable brightness and high contrast. New displays are able to adjust the power supplied, thereby increasing or decreasing the set parameters. With a completely white screen, the contrast is high – about 400 cd / m². When there are many dark shades in the picture, the light areas become visually brighter. This improves the image quality. The top-end IPS TV has a brightness indicator of 1000 cd / m².
- Screen curvature. New Amoled displays can be not only flat, but also semicircular. This option is not available for LCD TV. The pixels are arranged in such a way that it is impossible to change the design.
Important! All of the above benefits apply to Super Amoled. In the simple version of the novelty, the advantages are the same, except for brightness. Its settings are not as impressive as in the updated Super technology.
Disadvantages of Super Amoled
As with any development or new technology, Super Amoled is not without its drawbacks. The disadvantages include:
- High price. A large panel with LED light is more expensive than the TOP LCD IPS model. At the same time, in the budget segment, you can find the Samsung version with better characteristics than the LCD version of the same price.
- Fading tendency. Small LEDs gave high contrast and brightness, but became more prone to sun fading. Their resource is limited. Moreover, the speed of darkening depends on the preferences in the cinema. For example, if you watch dynamic scenes, the brightness will decrease over time. And when viewing static information, where there is more white, the LEDs may darken.
- Flickering of PWM diodes. Average flicker rate from 60 to 100 Hertz. People with sensitive eyes may notice this. So, discomfort will appear on prolonged viewing. But this defect can be slightly changed. It is enough to lower the brightness below 100% to reduce eye strain.
- Pentile – matrix structure, which implies the use of a smaller number of classic blue subpixels. As a result, the display uses only 5 rather than 6 subpixel options. This disadvantage is invisible when watching TV, although a person who constantly works with TV will notice a lack of shades.
All the disadvantages of the Super Amoled screen, except for the price, are almost invisible. But the picture quality, the thickness of the display and the reduction in power consumption are felt right after the purchase.
Prospects for development of Amoled and super amoled technology
Modern Amoled screens are equipped not only with Samsung TVs, but also tablets, mobile phones, smartphones. In the TV itself, the technology has been slightly changed. And it is usually called LED or Super Amoled matrix. And this is not surprising, because the color depth amazes users.
These matrices were originally developed for smartphones. The high contrast and quick response of the touch screen are big plus points for gadgets. But Super Amoled has become widely used to create TV.
According to experts, the cost of new TVs will not fall in the next 5-10 years. At the same time, the demand for equipment will grow. A confirmation of the development is the fact that Apple is planning to launch new smartphones with new Amoled screens.
The developer Samsung itself does not plan to abandon the new technology. This is confirmed by the increase in the number of new TVs with Super Amoled screens. They belong to the premium segment of home appliances.
3 TV models with Super Amoled
When buying a TV with a new screen, you need to pay attention to the OLED lettering. It is this that indicates the new structure of the matrix, characterized by high contrast and a good level of brightness. Among all the models, users especially appreciated:
- LG OLED 55C9PLA from 55 to 77 inches. Supports 4K format. Digital noise reduction is provided. There is Smart TV and many additional options. All digital standards are supported.
- Sony KD-65AG9 is a new TV format with a diagonal of 65 inches. 4K OLED screen. There is a convenient resolution in the concept of “sound from a picture”. Powered by X1 Ultimate processor with Android OS.
- Panasonic TX-55 EZR Premium 4K TV with powerful processor. The diagonal of the screen is 55 inches. Format 16: 9. There is protection from children. And can play all video formats from external media.
Samsung itself produces more smartphones with Amoled screens. Whether or not to buy equipment with a new matrix is at the discretion of the consumers themselves. At the same time, do not forget that the average life of an expensive and high-quality TV with Super Amoled is up to 10 years.
features of Amoled
Despite its shortcomings, Amoled’s technology is actively taking a strong position in the new smartphone market. More and more manufacturers are installing Amoled instead of IPS displays. In addition to Samsung, this kind of screen is already found in devices from Xiaomi, Apple, Honor from other manufacturers.
Advantages of AMOLED
Feature of the new screens: perfect black color, maximum brightness and absolute contrast. Some users scold the displays for being too bright, but this is what is considered an advantage. Thanks to this option, the readability of text and pictures in the sun is much higher than in smartphones with IPS.
Another major advance in Amoled technology is the reduction in display response times. It is only 0.1ms. For a person, this is an instant reaction. Whereas in IPS versions, the duration of the touch response is about 5 ms. This is also not enough, but in the process of dynamic games on a smartphone, the difference will be noticeable.
The minus of the screen is that it does not display perfect white. Shades go to the blue or green part of the spectrum. But the color shift was and always is. Ideal color reproduction does not yet exist on displays of any quality.
The main disadvantage is flicker or PWM. It is found in any display, including IPS. In Amoled technology, PWM becomes noticeable when the brightness decreases to 5-20% or to half. This effect cannot be noticed with the eye, but it is harmful to vision. Correct adjustment of the display brightness will help to reduce the disadvantage. It is enough not to lower it below 70-75%.Important. The relatively short display life is a myth. According to tests, even after 2 years of active use of the smartphone, the picture quality does not deteriorate.
Three models of smartphones with Amoled display
- Apple iPhone XS Max. This is a modern device with A12 Bionic processor. Diagonal Amoled of the screen is 6.5 inches. There are two main cameras with 12 MP and one front camera with 7 MP.
- Xiaomi Mi Mix 3 with a new 6.39-inch display. Matrix resolution 2340 by 1080p. There are also three cameras: two main 12 MP and one front 24 MP. Powered by an eight-core processor.
- Huawei Honor Magic 2 with Kirin processor Screen diagonal – 6.39 inches, resolution 2340 by 1080 p. Display proportions 19.5: 9, PPI 403. Operating system Android 9.0 (Pie).
From Samsung, which has introduced the new technology, the most popular smartphone with Amoled screen is Galaxy A9, 2018. The diagonal of its display is 6.3 inches, the resolution is 2220 by 1080 p.Most experts believe that Amoled is the future. And that soon the majority of new devices will be equipped with exactly these screens. And after them flat TVs will catch up.
