LCD TV upgrade LED backlight development focus

It is understood, using a new light source, LED light source (light emitting diode English, referred to as LED) LCD TV will be put on the market. Allegedly, the use of a new light source, LCD TV brightness, contrast will be greatly improved, the color will be more vivid, realistic.

It is understood that the imaging principle of the LCD panel is the use of the light source to display the image, which does not emit light, backlight technology directly affects the quality of LCD tv. At present, LCD TV usually uses cold cathode fluorescent lamp, with the advent of the era of the big screen, backlight brightness and uniformity of the requirements are also getting higher and higher. The contrast of the LCD TV of up to 100 to 1, the brightness is 550 LED backlight LCD TV; the contrast of 1400 to 1, brightness reached 900, and the color is more rich gorgeous. LED backlight LCD TV and the whole machine power is smaller, more energy saving, service life of up to 100 thousand hours.

According to industry analysts, LED backlight LCD TV market price will not be higher than the ordinary LCD TV too much. Although the price may be higher at the beginning, but now the country is developing the technology, the capital is also actively enter the field, so the price will soon be pulled down.

Wu Ling, director of major project management office of the national semiconductor lighting project, said that in the future to increase investment in research and development, set up a research platform at the national level, and to the enterprise as the main body, the development of China's semiconductor lighting industry, LED. Ding Wenwu, deputy director of the Ministry of information industry of electronic information products management department stressed that the Ministry of information industry in November 17th formally established the working group of semiconductor lighting technology standard, is a sign of semiconductor lighting into the fast track of development.

Experts said that the world's R & D and manufacture of LED LCD TV backlight brand two or three. The reporter learned from Amoi recently, they have developed China's first LED backlit LCD tv. According to the household of Amoi Electronics Division Marketing Manager Qu Guoqiang introduction, the product has been with mass production conditions, but the time to market and price has not been determined.
