What’s the classification of the display screen?

With the development of the technology, the touch screen becomes more and more popular, especially for the mobile phone screen. As we know, so many display brands occurred in the mobile phone market, such as the LG Display Screen, Nokia Display Screen, HTC Display Screen and so on. But do you know what’s the classification of the display screen?
1. TFT（Thin Film Transistor）
TFT (Thin Film Transistor), named thin-film field-effect transistor, each liquid crystal pixel on the LCD monitor are driven by the thin-film transistor integrated in the subsequent, which can get high brightness, high speed, high contrast display screen, TFT is an active matrix liquid crystal displays.
LCD, TFT-LCD is a thin-film transistor liquid crystal display, is “true color” (TFT), it not only improves the speed of response of the display but can accurately control the display gradation.
2. UFB LCD Displays
UFB LCD, with ultra-thin, high-brightness characteristics. UFB-LCD is designed for mobile phones and PDA. It is also famous with the characteristics of ultra-thin, high-brightness. And in order to obtain better image quality, the screen can reduce the pixel pitch.
By contrast of the UFB LCD is twice of STN LCD, and the power consumption is less than the TFT display, and the selling price can be comparable with the of the STN display.
3. STN Screen
STN stands for Super The Twisted, we used grayscale screen phone, which materials are the STN. And the biggest advantage of STN is the low power consumption, power-saving. On the whole, the performance of the STN screen color is worse than the above screens.
Leaving aside the grayscale STN, now STN can be divided into CSTN and DSTN. CSTN, named Color STN transmissive LCD, both in normal light and dark light, the display is very good. In the outdoors, especially in daylight, it is difficult to clarify the display of the screen, while the backlight, which needs consume power to provide light.
4. AMOLED
Active-matrix organic light emitting diode panel (AMOLED) is going to be the next-generation display technology, including Samsung Electronics, LG, Philips attaches great importance to this new display technology.
In addition to Samsung Electronics and LG, Philips regard large-size AMOLED products as the main direction, Samsung SDI, AUO to small and medium size for the direction of development.
As for the innate performance of the quality, efficacy and cost, by contrast, AMOLED is better than TFT LCD a lot, Which is the reason that why many international companies still develop the AMOLED market despite the yield is difficult to break.
As for the display performance, the AMOLED reaction speed is faster, higher contrast, wider perspective, which also is the AMOLED inherently better than TFT LCD; Otherwise AMOLED with self-luminous features, without the backlight, so it can be produced thinner than TFT; There is a more important feature, without the backlight, AMOLED can save the cost of backlight module 30% to 40% than TFT LCD.
