The Main Features of TFT Screen

With the maturity of TFT technology in the early 1990s, color liquid crystal flat panel displays developed rapidly. In less than 10 years, TFT-LCD has grown rapidly into a mainstream display, which is inseparable from its advantages. The main features are:
(1) Good use characteristics: low voltage application, low driving voltage, solid use safety and reliability are improved; flat, thin and light, saving a lot of raw materials and use space; low power consumption, its power consumption is about one-tenth of CRT display, and reflective TFT-LCD is even only about one-hundredth of CRT, saving a lot of energy; TFT-LCD products also have specifications, models, sizes, variety, convenient and flexible use, easy maintenance, update, upgrade, long service life and many other characteristics. The display range covers the application range of all displays from 1 inch to 40 inches and large projection planes, and is a full-size display terminal; the display quality ranges from the simplest monochrome character graphics to high resolution, high color fidelity, high brightness, high contrast, and high response speed of various specifications and models of video displays; the display mode includes direct view, projection, perspective, and reflection.
(2) Good environmental protection characteristics: no radiation, no flicker, no harm to the health of users. In particular, the emergence of TFT-LCD electronic books and periodicals will bring mankind into the era of paperless office and paperless printing, triggering a revolution in the way humans learn, spread and remember civilization.
(3) It has a wide range of applications and can be used normally in the temperature range of -20℃ to +50℃. The low-temperature working temperature of TFT-LCD after temperature hardening can reach minus 80℃. It can be used as a mobile terminal display, a desktop terminal display, and a large-screen projection TV. It is a full-size video display terminal with excellent performance.
(4) The manufacturing technology has a high degree of automation and good large-scale industrial production characteristics. The TFT-LCD industry technology is mature, and the yield rate of large-scale production reaches more than 90% [%].
(5) TFT-LCD is easy to integrate and upgrade. It is a 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 single-crystal silicon TFT-LCDs. In the future, there will be TFTs made of other materials, both glass substrates and plastic substrates.
