LCD panel backlight LED dosage increased by 3 times in 3 years

According to the analysis of market research agency DisplaySearch, because the light emitting diode (Light emitting diodes, LED) quickly being used in the Notebook PC notebook computer panel, but also have a good chance in the LCD TV panel last year, the world has about 8 billion LED, is applied to the liquid crystal panel backlight. It is expected that by 2012, LED backlight will be more widely applied to 1 inch to 70 inch LCD display, LCD backlight source LED using a number of time for the world, will be as high as 34 billion, compared with 2008 growth of more than 300%.

DisplaySearch latest the LED backlight LCD research report pointed out that the global LED shipments in 2008 a total of about 70000000000 stars, in the display field application are mainly LED outdoor billboards and LCD backlight panel. Among them, LED outdoor billboards in 2008 about the use of 10 billion 900 million LED, accounting for about 15% of all LED shipments. LCD panel backlight consumes a total of 8 billion LED, accounting for the proportion of all LED shipments accounted for 11%. The main use of LED backlight 5 applications, namely, small and medium size, Notebook PC, desktop display, industrial monitors, as well as high-end LCD TV, etc..

With LED outdoor billboards and LCD backlight rapid growth, DisplaySearch estimates that by 2012, global LED shipments will reach 167 billion, which applied to the display area of the LED, the light is billboards as high as 24 billion, LCD backlight more will reach 34 billion, accounting for all shipments than LED weighing 34.7%

Management in cost structure, heat dissipation and luminous efficiency and so on at the same time, considering various factors, low current LED products will become the mainstream of large size LED backlight. As for the use of more than 350 Ma of high-power LED products, due to the limitations of heat issues, will be the main lighting applications.
