Main features of TFT LCD display:

1. High degree of automation of manufacturing technology and good characteristics of large-scale industrial production. The TFT-LCD industrial technology is mature, and the yield of large-scale production reaches more than 90 [%].

2. The application range is wide. It can be used normally within the temperature range from - 20 ℃ to + 50 ℃. The low-temperature working temperature of TFT-LCD after temperature reinforcement treatment can reach - 80 ℃. It can be used as mobile terminal display, desktop terminal display, and large screen projection TV. It is a full-size video display terminal with excellent performance.

3. Good environmental protection characteristics: no radiation, no flicker, no damage to the health of users. In particular, the appearance of TFT-LCD electronic books and periodicals will bring mankind into the era of paperless office and paperless printing, and trigger a revolution in the way of human learning, spreading and recording civilization.

4. TFT-LCD is easy to be integrated and updated. It is the combination of large-scale semiconductor integrated circuit technology and light source technology, and has great potential for continuous development. At present, there are amorphous, polycrystalline and monocrystalline silicon TFT-LCD. In the future, there will be TFTs of other materials, including glass substrate and plastic substrate.

TFT liquid crystal display is characterized by good brightness, high contrast, strong sense of hierarchy and bright colors, but it also has the disadvantages of relatively high power consumption and high cost. TFT liquid crystal technology accelerates the development of mobile phone color screen. Many of the new generation of color screen mobile phones support 65536 color display, and some even support 160000 color display. At this time, the advantages of TFT's high contrast and rich color are very important.
