According to the Taiwan Information Technology Information Center (MIC), LED backlight applications have gradually shifted from Japanese manufacturers to manufacturers in the United States, South Korea and Taiwan in recent years, from small size to full size, from the Japanese market to the global market. However, due to the high cost and poor heat dissipation, and the module specifications have not been standardized, the current LED backlight is still only for the NB products that are thin and light, the penetration rate is only slightly higher than 10%, and the larger size of the Monitor and TV loading rate are still very low. It is expected that with the improvement of LED luminous efficiency, the decline of LED chip prices, and the establishment of module standardization, under the thrust of brand manufacturers and the thrust of the I board factory, the NBLED backlight loading rate will continue to grow, and by 2011, the global NB product LED The backlight loading rate may exceed 50%, becoming the mainstream backlight.

Intensive news, MIC pointed out that the biggest difference between LED backlight and CCFL backlight is that LED backlight has mercury-free, power-saving, package thickness of only 0.4-0.6mm, and low power consumption (currently 40-inch TV power consumption is about 160W), high color saturation and other advantages, but because LED backlight has the disadvantage of poor heat dissipation, and the current cost is still high, the calculation of 40-inch TV module requires 360 US dollars, plus LED backlight technology is still in the development stage, module Not standardized (such as different ConvertorBoard, different Pins, etc.), but also facing the next generation of CCFL mercury-free, OLED and SED display technologies, W-OLED and CNT and other next-generation backlights, so the current LED backlight The main application of the source is still more products in small and medium size, and the application ratio of Monitor and TV is still very low.
Among them, NB products have always been aimed at thin and light. Since the Japanese manufacturers FUJITSU and SONY took the lead in 2005, after the manganese ED backlight, other NB manufacturers have followed suit. In 2008, including TOSHIBA, ASUS, APPLE, DELL, HP, ACER, LG, lenovo and other NB manufacturers have launched LED backlight NB products, statistics, by May 2008, NBLED backlight loading rate has been 10%. It is expected that with the continuous improvement of LED luminous efficiency and the continuous decline of LED chip prices, with the development of standardization of module specifications, the LED backlighting rate of NB products may exceed 50% in 2011 and 50%-60% in 2012. Become the mainstream backlight of NB.
