The main advantages of TFT display screen are as follows:
(1) Good performance: low voltage application, low driving voltage, improved security and reliability of solid use; planing, light and thin, saving a lot of raw materials and use space; low power consumption, its power consumption is about 1/10 of that of CRT display, reflective TFT-LCD is even about 1% of CRT, saving a lot of energy; TFT-LCD products also have many characteristics, such as specification model, size series, variety variety, convenient and flexible use, maintenance, update, upgrade, long service life and so on. The display range covers the range of all displays from 1 inch to 40 inches, as well as the projection of large planes, and is a full-size display terminal; display quality from the simplest monochromatic character graphics to high resolution, high color fidelity, high brightness, high contrast, high response speed of various specifications of video display; display mode has direct view type, projection type, perspective type, as well as reflective type.
(2) Good environmental protection characteristics: no radiation, no flicker, no damage to the health of users. In particular, the emergence of TFT-LCD electronic books and periodicals will bring human beings into the era of paperless office and paperless printing, which will lead to the revolution of human learning, dissemination and recording of civilization.
(3) The range of application is wide, which can be used normally in the temperature range from-20 ℃ to 50 ℃. The low temperature working temperature of TFT-LCD strengthened by temperature can reach minus 80 ℃. It can not only be used as mobile terminal display, desktop terminal display, but also large screen projection TV. It is a full-size video display terminal with excellent performance.
(4) The degree of automation of manufacturing technology is high, and the characteristics of large-scale industrial production are good. The technology of TFT-LCD industry is mature, and the yield of mass production is more than 90%.
(5) TFT-LCD is easy to integrate and update. It is the perfect combination of large scale semiconductor integrated circuit technology and light source technology, and has great potential for further development. At present, there are amorphous, polycrystalline and monolitic silicon TFT-LCD, with other materials in the future. TFT, has both glass substrate and plastic substrate.
