The main features of TFT display

With the maturity of TFT technology in the early 1990s, the rapid development of color LCD flat panel displays, less than 10 years, TFT-LCD rapidly grew into the mainstream display, which is inseparable from its advantages.

The main features are:

(1) good use characteristics: low voltage application, low drive voltage, solid use safety and reliability; Flat plate, and thin, saving a lot of raw materials and use space; Low power consumption, its power consumption is about one tenth of the CRT display, reflective TFT-LCD even only about one percent of the CRT, saving a lot of energy; TFT-LCD products also have specifications, size serialization, variety, easy to use and flexible, maintenance, update, upgrade easy, long service life and many other characteristics. The display range covers the application range of all displays from 1 inch to 40 inch and the projection large plane, which is a full-size display terminal; Display quality from the simplest monochrome character graphics to high resolution, high color fidelity, high brightness, high contrast, high response speed of various specifications of the video display; Display mode has direct view type, projection type, perspective type, and reflection type.

(2) Good environmental characteristics: no radiation, no flicker, no damage to the user's health. In particular, the emergence of TFT-LCD electronic books and periodicals will bring humans into the era of paperless office and paperless printing, triggering a revolution in the way humans learn, disseminate and remember civilization.

(3) Wide application range, from -20℃ to +50℃ temperature range can be used normally, after temperature hardening treatment of TFT-LCD low temperature operating temperature can reach minus 80℃. It can be used as a mobile terminal display, desktop terminal display, and can be used as a large screen projection TV, which is a full-size video display terminal with excellent performance.

(4) High degree of automation of manufacturing technology and good large-scale industrial production characteristics. TFT-LCD industry technology is mature, and the yield of mass production has reached more than 90[%].

(5) TFT-LCD is easy to integrate and replace, is the perfect combination of large-scale semiconductor integrated circuit technology and light source technology, and has great potential for continued development. There are amorphous, polycrystalline and monocrystalline silicon TFT-Lcds, and there will be TFTS of other materials in the future, both glass substrates and plastic substrates.
