The advantages of TFT LCD display part two

Other main features

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 is inseparable from its advantages. The main features are:

(1) Good use characteristics: low-voltage applications, low driving voltage, and improved safety and reliability of solid use; flat panel, light and thin, saving a lot of raw materials and use space; low power consumption, its power consumption is about CRT display One-tenth of that, reflective TFT-LCD is even only about one-hundredth of CRT, saving a lot of energy; TFT-LCD products also have specifications, models, and sizes in series, with various varieties, convenient 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 and large projection planes. It is a full-size display terminal; the display quality ranges from the simplest monochrome character graphics to high resolution and high color fidelity. Various specifications and models of video displays with high brightness, high contrast and high response speed; display methods include direct view, projection, see-through, and reflective.

(2) Good environmental protection characteristics: no radiation, no flicker, no harm to the health of users. 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 human learning, dissemination, and recording of civilization.

(3) Wide application range, it can be used normally in the temperature range from -20℃ to +50℃. The low temperature working temperature of TFT-LCD after temperature hardening treatment 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 the characteristics of large-scale industrial production are good. The TFT-LCD industry technology is mature, and the mass production yield rate has reached more than 90%.

(5) TFT-LCD is easy to be integrated and updated. It is a perfect combination of large-scale semiconductor integrated circuit technology and light source technology, and has great potential for continued development. At present, there are amorphous, polycrystalline and monocrystalline silicon TFT-LCDs. In the future, there will be TFTs of other materials, including glass substrates and plastic substrates.
