Main features of TFT LCD

With the maturity of TFT technology in the early 1990s, color LCD flat panel displays have developed rapidly. In less than 10 years, TFT-LCD has rapidly grown into a mainstream display, which has its advantages and is inseparable. The main features are:


(1) Good use characteristics: low voltage application, low driving voltage, solidification safety and reliability improvement; flat, thin and light, saving a lot of raw materials and space; low power consumption, its power consumption is about CRT display One-tenth, reflective TFT-LCD even saves about one percent of CRT, saving a lot of energy; TFT-LCD products are also available in specifications, sizes, and varieties, and are easy to use, flexible, and repairable. , easy to upgrade, long service life and many other characteristics. The display range covers all display ranges from 1" to 40" and the projection large flat surface 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 video display; display mode is direct view, projection type, perspective type, also reflective.


(2) Good environmental protection characteristics: no radiation, no flicker, no damage to the user's health. In particular, the emergence of TFT-LCD e-books will bring humanity into the era of paperless office and paperless printing, which will lead to a revolution in the way humans learn, spread and remember to cultivate civilization.


(3) Wide application range, from -20 ° C to +50 ° C temperature range can be used normally, the temperature-hardened TFT-LCD low temperature working temperature can reach minus 80 ° C. It can be used as a mobile terminal display, a desktop terminal display, or a 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 large-scale industrial production characteristics are good. The TFT-LCD industry is mature in technology, and the yield of large-scale production has reached 90% or more.


(5) TFT-LCD is easy to integrate and update, and it is a 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 single crystal silicon TFT-LCDs, and there will be TFTs of other materials in the future, both glass substrates and plastic substrates.
