[汽车修理知识]Features of TFT-LCD display

In less than 10 years from the early 1990s to the present, TFT-LCD has rapidly grown into the mainstreammonitor, This 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 of the reflective TFT-LCD, and even only about one percent of the CRT, which saves a lot of energy; TFT-LCD products also have specifications, models, and sizes in series, a variety of varieties, easy to use, flexible, maintenance, and renewal. , 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 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 that humans learn, spread, and remember civilization.

(3) The application range is wide, and it can be used normally in the temperature range from -20°C to +50°C. The low temperature working temperature of the TFT-LCD after temperature reinforcement can reach minus 80°C. 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 degree of automation of manufacturing technology is high, 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 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. 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.
