The characteristics and application of the TFT liquid crystal screen

- Nov 19, 2019-

Tft (thinfilmtransistor) refers to thin film transistors, that is, each liquid crystal pixel is driven by a thin film transistor integrated behind pixel points, so that it can display screen information with high speed, high brightness and high contrast. 


It is one of the best lcd color display devices at present, and its effect is close to that of crt display. TFT is now the mainstream display device on laptops and desktops. Each pixel of TFT is controlled by tft integrated on its own and is an active pixel. 


Therefore, not only the speed can be greatly improved, but also the contrast and brightness can be greatly improved, and the resolution can also reach a high level. 


Tft-lcd liquid crystal display screen is a thin film transistor liquid crystal display screen, that is, "true color" (tft) .tft liquid crystal has a semiconductor switch for each pixel, each pixel can be directly controlled by point pulse, so each node is relatively independent and can be controlled continuously, which not only improves the reaction speed of the display screen, but also accurately controls the color level of the display screen, so the color of tft liquid crystal is more true. Tft is an active matrix liquid crystal display device for thin film transistors. 


TFT liquid crystal display designs a field effect switch at each pixel point, so it is easy to realize true color and high resolution liquid crystal display device. At present, the tfttype liquid crystal generally realizes the color above 18bit, even the 24bit color, and in the resolution, vga (640 × 480), svga (800 × 600), xga (1024 × 768), sxga (1280 × 1080), and even uxga (1600 × 1200) have become a reality.
