What are the disadvantages of Samsung's main screen material Super AMOLED?

Organic light-emitting diode screen, the scientific name of organic light-emitting display, has the characteristics of self-luminescence, wider viewing angle, richer colors, remarkable energy saving and flexible bending, and is known as "dream display". Due to the above characteristics, this screen has become the first choice for many flagship mobile phones.

Only at present, 99% of the output of small and medium-sized screens in organic light-emitting diodes is monopolized by Samsung Display. It should be emphasized that Super AMOLED is not invented and monopolized by Samsung itself, but Samsung has been using Super AMOLED screens on its flagship models, giving people this wrong understanding. Super AMOLED is just one of the excellent display technologies of AMOLED.

Knowing the advantages of AMOLED screen and the origin of Super AMOLED, let's talk about its disadvantages:

1, screen burning phenomenon. Burn-in refers to the screen displaying a still image for a long time, which will leave a residual image. At present, there is no complete solution to this problem, and it can only be optimized. That's why Apple gives users an opportunity of an organic light-emitting diode screen for iPhone X on the official website.

2. Because AMOLED is self-luminous, different pixels may have different brightness during the aging process, so the color cast problem is more serious (but LCD screen with backlight panel is not to worry about);

3, AMOLED emphasizes green (green is too bright), which is amazing at first glance, but it will be visually tired after watching it for a long time;

4, the screen life is short, the life of AMOLED is usually only 5000 hours, which is at least 10000 hours lower than that of LCD;

5. Compared with the LCD with the same resolution, the graininess is stronger: compared with the RGB lattice arrangement of LCD, the PGB lattice arrangement of AMOLED determines its inherent shortcomings in principle: strong graininess, protruding burrs, serious sawtooth feeling and so on. At present, this problem can be solved to a great extent through 2K screens, such as Samsung's S8. However, the reality is that many manufacturers will not use the 2K screen because of cost or power consumption, but use the 1080P screen, and the graininess problem still exists.

With Apple using Super AMOLED screen for two consecutive years, this thin, light, power-saving and flexible screen has become the mainstream of the smart phone industry, and it is mainly used in high-end models.

However, Samsung OLED screen still has many shortcomings, mainly as follows:

1, screen burning problem. Because the display principle of the organic light-emitting diode screen is that the pixel itself emits light, when a pixel displays the same color for a long time, it will leave an afterimage on the screen. You can go to the store to observe the display organic light-emitting diode screen prototype in the store, and there will be screen burning problems more or less. However, screen burning can be avoided by changing the display content of the screen regularly, and with the evolution of organic light-emitting diode technology, the phenomenon of screen burning in commonly used organic light-emitting diode screen mobile phones has rarely appeared.

2. Blue pixel attenuation problem. The OLED screen consists of three basic sub-pixels: red, green and blue, in which the attenuation speed of the blue pixel is faster than that of the red and green pixels. Therefore, the OLED screen will obviously yellow after long-term use. Fortunately, with the upgrading of technology, the attenuation of blue pixels will take at least three years to see. Generally, users should change to a new machine at this time.

3.PWM dimming problem. Because the OLED screen has no backlight, when it is necessary to change the brightness, it is done by adjusting the stroboscopic of the pixel. Although human eyes can't feel the flicker of the screen, it is easy to cause fatigue and dryness of human eyes under low-frequency PWM dimming, and some users even feel dazzling and dizzy when using the OLED screen. The lower the brightness of the screen, the slower the flicker frequency of the OLED screen, and the greater the pressure on human eyes, so the OLED screen is not suitable for long-term use in too dark environment.

In addition, compared with the traditional LCD screen, the color of Samsung Super AMOLED screen is more vivid. Although it is eye-catching, it will give people an unreal feeling in some cases. So there are still many users who prefer LCD phones.

208 days service life? Visually impaired? With the advantages of Super AMOLED, these disadvantages come.

"Spicy eyes" is some people's initial impression of Super AMOLED screen, and this is also the first shortcoming of Super AMOLED material: it affects vision! You may be surprised that this screen will affect your eyesight. In fact, all screens will affect your eyesight, because there will be blue light that is harmful to people's eyes. But Samsung's Super AMOLED is not only this problem, but also other factors that affect vision.

Thanks to the rich color presentation of Samsung Super AMOLED, I remember that the screen of I9 100 is too bright, which makes people's eyes tired easily, so staring at the screen for a long time affects their eyesight.

Second, burn the screen! I believe many people should be familiar with Super AMOLED screen burning. Because of the limitation of technology, the screen of mobile phone will age or linger after being used for a long time. This is aging. Of course, there is no good solution at present, only don't keep the same picture for a long time, or change the screen saver frequently.

There is also a short life span, which is obviously unacceptable to many people. After all, it costs hundreds or even thousands of dollars to change a screen. The result tells me that the life span is very short. At present, the service life of the general Super AMOLED is 5000 hours, which is equivalent to 208 days. So this is unacceptable to mobile phone users? Of course, this statement is also inaccurate, because we will not always light up the screen, so the mobile phone screen has been said for about 2 years.

Finally, the price. The price of a Super AMOLED is much more expensive than that of an ordinary LCD screen. You know, it costs 2228 yuan for an iPhone to change screens, which is unacceptable for mobile phone users.

However, no matter how many shortcomings you say it has, it is now the mainstream screen, so we hope BOE can break the shortcomings of Samsung screen and make the domestic screen become the world screen.

Although Samsung's Super AMOLED has many shortcomings, it is undeniable that this screen is good, because other ordinary screens will have more shortcomings. In fact, the OLED screen is not original by Samsung, but the mass production of Samsung makes it shine in front of everyone.

Disadvantages color reproduction degree is not true enough. In order to satisfy users, Samsung Super AMOLED has turned the screen too bright. Because the color is too strong, the picture presented is a bit fake. Some users don't like such bright colors, so Samsung is gradually returning to normal now. Actually, I also like this kind of screen very much. Do you like color screens?

There is a screen burning phenomenon. If Samsung's Super AMOLED screen stays under an image for too long, it is easy to appear afterimages, which will affect the perception.

It will have a grainy feeling. The familiar one plus mobile phone uses the Samsung Super AMOLED screen, so many people spit out that its screen will be grainy. Due to the development of technology, in fact, as long as it is not obsessive-compulsive disorder, the current AMOLED screen basically does not see graininess.

It's too expensive. The price of this screen is much more expensive than other screens, which invisibly increases the price of mobile phones.

Advantages can be bent. Because organic light-emitting diodes are easy to bend, the screens of many curved screen mobile phones on the market are also from Samsung Super AMOLED screens.

There is no light leakage, and the organic light emitting diode is self-luminous, so it will not leak light like the LED screen.

Low power consumption, Samsung Super AMOLED basically does not work when displaying black, so the screen can effectively reduce the power consumption of the mobile phone when displaying black.

What do you think of Samsung's Super AMOLED screen? Have you ever used it?

I came uninvited, and I saw some high-priced answers upstairs, all of which were nonsense, and I heard them through hearsay on the Internet. What is short-lived and easy to get old is bullshit. I went to a fish and found a s6e screen with tickets from China Bank, which is normal. There are many problems in the American and Korean versions. Why? Most of them are refurbished.

At present, domestic small factories can't make curved amoled, unlike 6p, which only needs 100, and the original s6e screen needs more than 1000. So there are many screen splitters.

The biggest disadvantage of amoled is that your penetration rate is not high.

You'll know when you use it. It's really good. What's the use of talking so much? The most important thing is bright colors, pleasing the eyes and saving electricity.

No light leakage! What makes users feel the best is that black does not emit light, pure black, and it will never leak light.

Refer to the screen of Xiaomi 6, not to mention the light leakage at the top. You can't stand this black and white.

Aging screen burning does exist, and a picture will appear after a long time. Except for the monitor, this problem will not occur in normal use.

There is another problem with amoled, which is the most influential one at present.

There is little difference in the normal use of smears, but if you look closely, there are indeed smears.

When I read late into the night, the whole screen was black and the font was white, which was obvious.

Samsung Super AMOLED screen is favored by domestic and foreign mobile phone manufacturers because of its light material, bright color and better power saving effect. Although Super AMOLED is good, it still has many shortcomings.

Super AMOLED is not good for eyesight in the long run.

Because super AMOLED is too bright in color and has poor color reproduction ability, it is easy to cause eye fatigue after watching for a long time, thus affecting vision.

Super amoled is easy to age, and the phenomenon of screen burning means that the screen displays still images for a long time, which will leave residual images. AMOLED is self-luminous, and it has the phenomenon of burning screen, as shown above.

Compared with IPS, TFT and LCD, Super amoled has higher maintenance cost. It is extremely valuable to maintain the screen of Super AMOLED once. Samsung A-screen mobile phones change screens from five or six hundred to thousands, but Apple's screen is cheaper (Apple is the display of LCD).

Disadvantages? When the screen shows white, the color temperature at the top of the screen is pure white, while the color at the bottom is slightly off color because of different viewing angles.

In addition, the temperature is very low this winter, and the warning screen will turn white when the outdoor temperature is low. This problem has been reflected in Samsung's official forum, but it is not guaranteed, because the indoor temperature is completely normal when it is high.

The biggest disadvantage is that all amoled screens sold in the market use low-frequency pwm dimming, especially when the screen brightness is low. Not suitable for non-Buddhist mobile phone users. I don't know if it's a personal constitution. Personally, I feel that if I fill it two or three times a day, I will have a headache and be agitated. I don't want to sleep, just need to rest for a while.

The best screen at present is Samsung's.
