2010 LED backlight LCD TV will account for 6%

Since the second half of last year, the flat-panel TV manufacturers began to LED TV as a high-end products to promote, such as SHARP, SONY, Samsung, Hisense and other brands have released a new LCD TV with LED backlight system. It is predicted that in 2009 the LCD TV market will have 2%-3% products are LED backlight TV, in 2010 this proportion will rise to 6%.

According to the insiders evaluation of the industry, with a 42 inch LED backlight LCD TV backlight module as an example, 2009 LED prices will decline quickly, reduce the cost to less than 40% of the whole machine, this will prompt more manufacturers began to consider the application of the new type backlight materials.

In each LED backlight module requires the use of 500 LED lights to calculate, in 2009 the global LED backlight TV production required LED lights will reach 2 billion 250 million, in 2010 reached 5 billion 500 million. For notebook LED backlight system, the 2009 LED light demand will reach 2 billion 520 million, in 2010 will reach 4 billion 740 million. Thus, LED backlight material industry in the next three years will show a trend of multiple development.

At present, LED back light source material is mainly divided into two kinds of white LED backlight and RGB-LED backlight. The former compared with the latter, low technical requirements, the cost is cheaper, the LCD TV to achieve ultra-thin body design is an auxiliary means, make TV thickness and weight are greatly reduced, such as Samsung, the world's thinnest 6.5mm LCD TV, SONY 9.9mm ZX1 series liquid crystal TV are used in white LED backlight light source.

The advantage of RGB-LED backlight material is mainly reflected in the improvement of image quality. RGB-LED backlight system, with the application of the regional activation driven technology, can achieve one million: 1 ultra-high dynamic contrast, comparable to the quality of plasma TV effect. But the RGB-LED back light source of high technical threshold, and the thickness of the white LED backlight module system not so easy to achieve lightweight, the main application is the high quality requirements of the flagship model, such as the SHARP XS1A Series LCD TV, SONY LCD TV X4500 series, the SHARP XS1A Series LCD TV screen thickness of only 23mm, is currently the thinnest RGB-LED backlight LCD tv.

In addition, the use of LED backlight system can effectively reduce the energy consumption and solve the problem of uneven brightness of the screen and leakage. It is understood that this year, including LG, Toshiba, Hitachi, Changhong and other brands have launched high-end LED backlight LCD TV products, LED backlight technology has become the technology of LCD TV and a trend of screen full HD, the ultra-thin, driving speed.
