In the market the opportunity to show the size of the LED backlight manufacturers active position

Medium size LED backlight application industry does not have a clear division, 10 inches is generally referred to as small and medium size, 10 inches or more commonly known as the large size, 10 inches to 17 inches display monitor and LCD panel backlight can be regarded as a typical mid size LED backlight applications. Small size backlight market represented by mobile phone can be said that LED has dominated the market stability, and for many years, with TV as the main application of large size backlight market has not yet started, LED will enter the market, the road is still long. At this point, the size of the application of the opportunity to display backlight.

Notebook LED backlight penetration in 2008 increased significantly, some institutions predict that in 2008 the market penetration rate of about 13% to 15%, in 2009 will have the opportunity to break through the 40%, the future of the LED industry to become a new kinetic energy. Experts believe that hot and expensive is currently two of the most difficult LED backlight application problems of large size, these two problems have yet to be time to solve, because increasing the luminous efficiency of LED and falling prices is an inevitable trend, when the luminous efficiency is doubled, the number of pieces of LED can be reduced, the heat source is reduced, and the cost is also drop. The industry is generally estimated to wait for this trend for two years before LED can be widely used in large size LCD backlight. Jiangsu Wenrun photoelectric Co., Ltd. chief engineer Bao Shulin believes that the light emitting diode (LED) is applied to the LCD backlight trend is very clear, the small size of the fastest pace of import, as for the use of notebook computers in the size and use of large size LCD TV, replace the latter most. Because the LED has better color saturation, driving fast, can reduce the light leakage and increasing the contrast and other advantages, in the video dynamic performance of the most able to play out. However, the size of the large number of LED panels needed, making the heat problem continues to plague, has not been a more economical solution. Another problem is that the price is too high, because not only more than the number of stars, and if you want to ensure that the quality must select the wavelength of LED, which is equivalent to the cost of upgrading. Therefore, this period is the best time for LED applications.

Jin Bo, deputy director of the Central Institute of Shanghai radio and television (Group) said, LED backlight size is mainly used for notebook computers and portable PC 10 inch to 17 inch LCD panel backlight. He believes that since the second half of 2007, the notebook computer panel with white light LED as the backlight source gradually developed, with white light LED as the light source of benefits, mainly is the thickness of the thinner, lighter weight, smaller power consumption, can enhance the convenience of laptop computer.

In addition, the issue of environmental protection is another focus. Jin Bo believes that consumer concern for environmental issues, as mercury free notebook computer brand manufacturers to actively import LED as backlight, especially the apple computer announced in May 2007 his notebook computer will be using LED as a backlight, notebook computer manufacturers began to drive using the LED backlight technology trend. As a result, the white light LED applications in the notebook panel boom will continue. At present, the use of white LED as a laptop backlight source panel manufacturers to TMD the most active, so the first half of 2007 before the use of LED backlight notebook panels are mostly from the TMD panel. While South Korea's two largest panel makers Samsung and LG Philips LCD in China and Taiwan's AU Optronics (AUO) and Chi Mei Optoelectronics (CMO) also in the second half of 2007 have launched notebook computer panel LED backlight, seize the market actively.
