In response, he proposed compensation film, multi-domain vertical arra
22、ngement (WVA) and the plane drive mode (IPS). Compensation method of viewing film some improvement, but not ideal. Developed by Fujitsu and Hitachi WVA IPS can be developed to achieve more than about 160 angle up and down, and in late 1999 and introduced the product. Society for Information Display
23、International Conference STD99, the South Korean Hyundai released the fringe field-driven mode (fringe-field switching), similar to the mode of IPS, a significant improvement in performance, LCD viewing angle and optical efficiency are very excellent. Recently, Samsung has developed a combination of
24、 the edge electric field and the vertical arrangement of the expansion of perspective techniques. From these technological advances of view, the perspective of barriers will be history. Dynamic images in the LCD display, high-speed moving images will appear tail, ghosting and other phenomena, this i

To solve the single polarizer mode concave reflective electrode of arbitrary reflection angle and contrast and other issues affecting the use of holographic recording film to produce holographic-type directional color filter. And a reflective film, allowing the incident angle other than 30
32、internal reflection angle of incident light at the point, as compared with the standard reflector, reflectivity increased 3.5 times. Meanwhile, the color reproducibility, color shift with angle of incidence have shown a higher than normal through-type color filter excellent performance. For the effe

In 1999 Japan Electronics Show, Toshiba has introduced a 15-inch UXGA LTPS TFT-LCD, is the worlds largest to date the size of p-Si TFT-LCD products. In the same show, Sony also features a 14.1-inch LTPS TFT-LCD. In,
35、type p-Si TFT-LCD, Toshiba introduced 4-inch VGA and 6.3 in. XGA products, resolution is more than 200 ppi. Since 1996, pSi TFT-LCD put into trial production in Japan has developed very rapidly, technology is increasingly mature, this is also the last two years overseas, the Japanese large-scale shi

According to the revitalization
46、of the Japanese electronics industry association in March 2000 results published in 1999 in the number of LCD products increased 34% over 1998, especially in PC with LCD Monitor products, an increase of 10.3%, while the monitor products are decreased by 12%. The Sharp is more optimistic forecast, th
47、e 20005, the LCD TV will replace CRT. In a good market prospects driven, TFT-LCD industry to become investment hot spots in recent years, one of East Asia. LCD advantage with its unique formation of a huge industry, but still the face of strong pressure of competing, one from the traditional low cos
48、t of CRT, but also from being the development and growth of other flat-panel display technology, such as PDL, FED, OEL, in particular the evolving information technology market requirements. I believe in the new century, the LCD display will be even greater development, which is inseparable from the
49、 advantages it has. LCD Monitor I have been low voltage. Power consumption, not the slightest radiation, no harm to human health completely flat, no flash, no distortion, visual area, thin and light, fashionable and diverse, it can save space, more applications to adapt to anti-interference ability much better than CRT monitors. The previous perspective has some flaws, such as size, brightness and contrast is not big enough and so, as technology continues to improve, and now the latest TFT-LCD displays have made conside
