Why is the environmental protection of TFT LCD good? Mainly from the following aspects can be reflected:

1. The TFT LCD environmental characteristics: no radiation, no flicker, no damage to the user's health. Especially the emergence of TFT-LCD electronic books, will bring mankind into the paperless office, paperless printing era, triggering a revolution in the way humans learn, spread and record civilization.

2. TFT liquid crystal display range of application: from -20 °C to +50 °C temperature range can be used normally, after temperature reinforced processing of TFT-LCD low temperature working temperature can reach minus 80 °C. Both as a mobile terminal display, desktop terminal display, but also for large screen projection TV, is a full-size video display terminal with excellent performance.

3. The degree of automation of TFT-LCD manufacturing technology: good characteristics of large-scale industrialized production.

The main features of TFT-LCD are:

(1) The use of good characteristics: low-voltage applications, low drive voltage, solidified use of security and reliability; flat, and thin, saving a lot of raw materials and use of space; low power consumption, its power consumption is about one tenth of the CRT display, reflective TFT-LCD or even only about one percent of the CRT, saving a lot of energy; TFT-LCD products and specifications, models TFT-LCD products also have many features such as serialized specifications, various sizes, convenient and flexible usage, easy maintenance, updating and upgrading, and long service life. Display range covers the application range of all displays from 1 inch to 40 inches and projection of large planes, 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 models of video displays; display mode has a direct view type, projection type, see-through type, but also reflective 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, will bring mankind into the paperless office, paperless printing era, triggering a revolution in the way humans learn, spread and remember to plant civilization.

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

(4) The manufacturing technology is highly automated and has good characteristics of large-scale industrial production, the TFT-LCD industry is mature and the yield rate of large-scale production is over 90%.

(5) TFT-LCD is easy to integrate and update, and is a perfect combination of large-scale semiconductor integrated circuit technology and light source technology, with great potential for continued development. Currently there are amorphous, polycrystalline and monocrystalline silicon TFT-LCD, the future will have other materials TFT, both glass substrate and plastic substrate.
