Five Main features of TFT-LCD

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

(1) Good usage characteristics: low-voltage application, low driving voltage, solid-state use with improved safety and reliability; flat, light and thin, saving a lot of raw materials and usage space; low power consumption, its power consumption is about CRT monitor One-tenth of that of CRT, reflective TFT-LCD is even only about one percent of CRT, saving a lot of energy; TFT-LCD products also have serialized specifications, models and sizes, various varieties, easy and flexible use, maintenance and update , easy to upgrade, long service life and many other features. The display range covers the application range of all displays from 1 inch to 40 inches as well as large projection surfaces. It 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, high-response video monitors of various specifications and models; display methods include direct-view, projection, see-through, and reflective.

(2) Good environmental protection characteristics: no radiation, no flicker, no harm to the user's health. In particular, the emergence of TFT-LCD e-books will bring mankind into the era of paperless office and paperless printing, triggering a revolution in the way mankind learns, communicates and records civilization.

(3) It has a wide application range and can be used normally in the temperature range from -20°C to +50°C.The low-temperature operating temperature of TFT-LCD after temperature reinforcement treatment can reach minus 80°C. It can be used as a mobile terminal display, desktop terminal display, or 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. TFT-LCD industry technology is mature, and the yield rate of mass production reaches more than 90%.

(5) TFT-LCD is easy to integrate and replace. 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 monocrystalline silicon TFT-LCDs. In the future, there will be TFTs of other materials, both with glass substrates and plastic substrates.
