The use principle of LCD liquid crystal display screen
with the maturity of TFT technology in the early 1990s S, color LCD flat panel displays developed rapidly. In less than 10 years, tft LCD has rapidly grown into mainstream displays, this is inseparable from its advantages.
(1) Good use characteristics: Low Voltage application, low driving voltage, improved safety and reliability in solid use; Flat and light, saving a lot of raw materials and space. Low power consumption, its power consumption is about 1% of CRT display, reflective tft LCD is even only about of CRT, saving a lot of energy. Tft LCD products also have many characteristics such as Specification, size serialization, variety, convenient and flexible use, easy maintenance, update and upgrade, long service life, etc. The display range covers the application range of all displays ranging from 1 inch to 40 inch and the projection large plane, which is a full-size display terminal. The display quality ranges from the simplest monochrome character graphics to video displays of various specifications and models with high resolution, high color fidelity, high brightness, high contrast and high response speed. The display modes include direct view type, projection type, perspective type and reflection type.
(2) 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 human beings into the era of paperless office and paperless printing, triggering a revolution in human learning, spreading and recording civilized ways.
(3)Wide range of application, from- It can be used normally in the temperature range of 20 ℃ to 50 ℃, and the low temperature working temperature of tft LCD after temperature reinforcement can reach minus 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.
