advantage:1、 Compared with the traditional LCD, AMOLED has a very thin screen and can integrate a touch layer into the screen, so it has more advantages in making ultra-thin machines.
in this paper, we introduce the development of AMOLED2、 AMOLED is self luminous.

What are the advantages and disadvantages of AMOLED?

single pixel doesn't work when displaying black color, and low power consumption when displaying dark color.
therefore, AMOLED can save power when displaying dark color.
moreover, it has hundreds of times contrast of traditional LCD, and it won't leak light.
in addition, AMOLED can save power when displaying dark color3、 AMOLED has a certain flexibility.
it is less likely to damage than LCD screen on glass substrate.
AMOLED is more flexible than LCD screen on glass substrate4、 The color gamut of AMOLED and super AMOLED are very wide (but seriously biased).
the color gamut of AMOLED and super AMOLED is very wideDisadvantages: AMOLED has obvious advantages.
and some advantages are ten times better than LCD in terms of detection value, but why is OLED still not unified now? In addition to the problem of production capacity, it is more of its major shortcomings that make people frown.
however, the relevant manufacturers do not mention these fatal shortcomings.
however, irresponsible media and unscrupulous editors in "some areas" of the planet have avoided the important and even reversed the black and white, misleading the public1、 AMOLED adopts the pixel arrangement of pentile.
the actual resolution can only reach two-thirds of the nominal resolution. In the case of low DPI, the sense of graininess will be very heavy, and obvious color dots can be seen at close range. All color block boundaries such as text, table, graphics need to be displayed with the assistance of adjacent pixels, which leads to serious and inevitable problems such as virtual edges and mixed colors2、 AMOLED emphasizes greenThe color temperature of AMOLED is still the problem of pentile.
the color temperature of AMOLED is still the problem of pentile3、 The contrast of AMOLED is very high.
however, when displaying dark pictures, color blocks are easy to appear, especially dynamic pictures (for non video compression problems, please refer to the report of Dr. Raymond soneira published by displaymate technology company in point 6 and below for details); Moreover, its ultra-high contrast comes from the non luminous black to some extent4、 Each pixel of AMOLED is an independent light emitter.
therefore, in the aging process, different pixels may have different aging degrees, resulting in different brightness, so the color deviation problem will become more complex!5、 Power saving? But only in the display of dark and black, because dark does not need to emit brighter light, black is not bright at all, but when white is displayed, AMOLED consumes more power than LCD! So why the UI of mobile phones using AMOLED screen is dark color.
but at present, the pictures of Internet, games, e-books and other applications are almost in high brightness color.
and the background color of most websites is white.
the background color of most websites is white6、 Although AMOLED color gamut is claimed to be 114% of NTSC.
a report from Dr. Raymond soneira, general manager of displaymate Technology Co., Ltd., shows that the color data of AMOLED display screen is not flattering, only 65000 colors can be displayed, and more colors are produced by software interpolation, The details of color quantity interpolation can be searched by Google.
Super AMOLED plus has the following advantages: 1; 2. More colorful.
2The screen has higher contrast and saturation, and better visibility; 3. The screen is thinner and the reaction speed is faster;Disadvantages: due to the technical difficulty, the yield is not high, so the cost is much higher than TFT;Samsung i9100 is using this screen, which is much better than TFT in terms of display effect and power consumption, and the screen graininess criticized by AMOLED plus has been basically solved
