手机参数介绍（Introduction of mobile phone parameters） Introduction of mobile phone parameters TFT LCD screen TFT (Thin Film Transistor) Thin Film field effect Transistor, namely refers to the each LCD liquid crystal display pixel point is driven by integration in the behind of the Thin Film Transistor, which can achieve high speed, high brightness, high contrast display screen information, TFT belongs to the active matrix liquid crystal display. TFT - LCD LCD is a thin film transistor type liquid crystal display screen, which is also known as true color (TFT), which not only improves the reaction speed of the display screen, but also controls the display color level accurately. TFT LCD display is characterized by high brightness, high contrast, high level and bright color, but there is also a lack of electricity consumption and high cost. UFB LCD screen UFB LCD, with its ultrathin, high brightness characteristics. Ufb-lcd, designed for mobile phones and pdas, features ultra-thin and high brightness features, which can reduce pixel spacing to achieve better image quality. UFB LCD contrast is twice that of the STN LCD screen in 65536 when the color brightness and TFT screen, and less electricity than TFT screen, the same way as the STN displays, and price is combined with the advantages of these two kinds of existing products. The STN screen The abbreviation of the STN is Super Twisted Nematic, we used the gray-scale of mobile phone screen is the STN, it has the advantage of low consumption, has the biggest advantage of energy saving, on the whole the STN screen with color performance is still far worse than the screen. The STN is mainly CSTN and DSTN. CSTN Color namely the STN LCD in normal light and dark line transmission type, display effect is very good, but in the outdoors, especially in the sun, it is hard to argue the qing and backlit display content need power supply, lighting light from the consumes electric power. Color order and resolution The color order is th
