color liquid crystal flat panel display (LCD) has developed rapidly

- Oct 09, 2019-

With the maturity of tft technology in the early 1990s, color liquid crystal flat panel display (LCD) has developed rapidly, and, tft lcd has grown into mainstream display in less than 10 years, which is inseparable from its advantages. Its main characteristics are as follows: 


(1) good application characteristics: low voltage application, low driving voltage, improved safety and reliability of solid use, flattening, light and thin, saving a lot of raw materials and use space. Low power consumption, its power consumption is about 1/10 of crt display, reflective tft lcd is even about 1% of crt, saving a lot of energy. TFT lcd products also have many characteristics, such as specification model, size series, variety, convenient and flexible use, maintenance, update, easy upgrade, long service life and so on. The display range covers the application range of all displays from 1 inch to 40 inches, as well as the projection of large planes, and is a full-size display terminal. Display quality from the simplest monochromatic character graphics to high resolution, high color fidelity, high brightness, high contrast, high response speed of various specifications of video display. The display mode has the direct view type, the projection type, the perspective type, also has the reflection type.

(2) good environmental protection characteristics: no radiation, no flicker, no damage to the health of users. In particular, the emergence of tft lcd electronic books and periodicals will bring human beings into the era of paperless office and paperless printing, which will lead to the revolution of human learning, spreading and memorizing civilization. 


(3) the range of application is wide, which can be used normally in the temperature range from-20 ℃ to 50 ℃. The low temperature working temperature of tft lcd strengthened by temperature can reach minus 80 ℃. It can not only be used as mobile terminal display, desktop terminal display, but also 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 the characteristics of large-scale industrial production are good. The technology of TFT lcd industry is mature, and the yield of mass production is more than 90%.


 (5) tft lcd is easy to integrate and update, which is the 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 monolitic silicon tft lcd, with other materials in the future. Tft, has both glass substrate and plastic substrate.
