TFT liquid crystal has a semiconductor switch for each pixel

- Jul 18, 2018 -

The TFT-LCD liquid crystal display is a thin film transistor type liquid crystal display, which is also a "true color" (TFT).

The TFT liquid crystal is provided with a semiconductor switch for each pixel, and each pixel can be directly controlled by a point pulse, so each node is relatively independent and can be continuously controlled, which not only improves the reaction speed of the display screen, but also can accurately control. The color gradation is displayed, so the color of the TFT liquid crystal is more true.

TFT liquid crystal display features high brightness, high contrast, strong layering, and bright colors, but there are also deficiencies in power consumption and high cost.

TFT liquid crystal technology has accelerated the development of mobile phone color screens. Many of the new generation of color screen phones support 65,536 color display, and some even support 160,000 color display. At this time, the high contrast and rich color advantages of TFT are very important.
