As we all know, there is certain relation between mobile phone display screen effect and
screen material. Since color screen came into market, the material has developed to Super AMOLED from STN,TFT, IPS. The introduction of them are as following:
STN is the short name of Super Twisted Nematic, which adds colorful filter on the traditional single STN LCD. STN is passive LCD, which can show 65,536 kinds of color at most.
Oppositely, TFT is active matrix LCD, which has high responsiveness, high lightness, and
high contrast. At the same time, TFT screen has three kinds of mobile phone display screens: 65536 color, 160 thousands color and 16 million color, which is more excellent than STN. IPS is based on TNT. Compared with common TNT, IPS is with broad visible angle, touch
no wave, and environmental. Super AMOLED is the higher version of AMOLED. Compared with former AMOLED, it abandons Touch+Display design, and makes the touch more
sensitive and good display effects under the sunshine.
Even though the mobile phone display screen material and technology of display is more
and more advanced, almost all of them is bar. In display creation, Samsung and LG release curved and flexible screen smart phone. Because of yield rate and production, they are not
the mainstream in the market now. If manufacturers can solve the battery life and shape
limit, there will be multi-kinds display screen in the near future.
