2011 NB LED backlight penetration of more than 50%

The information industry in Taiwan province of China market information center (MIC) pointed out that the LED backlight applications in recent years gradually from Japanese manufacturers to South Korea and the United States and China's Taiwan region manufacturers transfer from small size at full size, from the development of the Japanese market to the global market. However, due to the high cost of poor heat dissipation, and the module specification has not been standardized, the current LED backlight is still only appeal frivolous NB products, penetration is only slightly higher than 10%, the larger the size of the Monitor and TV carrying rate is still very low. As expected LED luminous efficiency, LED chip prices fell, and establish standardized modules, in tension and panel factory thrust under the brands NB, LED backlight carrying rate will continue to grow, in 2011 the global NB LED backlight products carrying rate could exceed 50%, become the mainstream backlight.

MIC pointed out, LED backlight and CCFL backlight LED backlight is the biggest difference, has no mercury, energy saving, the thickness of the package is only about 0.4-0.6mm, lower power consumption (currently 40 inches TV power consumption of about 160W), high color saturation and other advantages, but because the LED backlight has the disadvantage of poor heat dissipation, and the cost is still high. With a 40 inch TV calculation module need $360, LED backlight technology is still in development stage, and has not yet been module (such as Convertor Board, Pin number of different different foot, etc.) and CCFL with no mercury, OLED and SED and other next-generation display technology, W-OLED and CNT and other next-generation light source of the competition, so at this stage LED backlight is mainly used in small and medium size products more, as the ratio of Monitor and TV is still very low.

The NB has always been to the product because of light as the goal, since 2005, Japanese manufacturers FUJITSU and SONY pioneered the use of LED backlight, other NB manufacturers are starting to follow up to 2008, including TOSHIBA, ASUS, APPLE, DELL, HP, ACER, LG, Lenovo and other NB manufacturers have launched LED NB backlight products, statistics to 2008 in May, NB LED is equipped with backlight rate has been 10%. Expected with the LED luminous efficiency continues to improve, LED chip prices continued to decline, with the development of the module of standard specification, NB products equipped with LED backlight rate in 2011 is likely to exceed 50%, in 2012 reached 50%-60%, become the mainstream NB backlight.

As for Monitor although there are Samsung, CMO, ACER and other manufacturers to launch LED backlight products, but the current carrying rate of only 0.3%. Expected 2011 LED backlight carrying rate is still only 7%, in 2012 will be more than 10%. LED LCD TV is equipped with backlight rate because of cost factors, the existing carrying rate is lower, only 0.09%, the current application vendors only Samsung, SONY, LG and SHARP respectively, but also plans to launch 47 inch and 52 Inch panel in this year.

MIC LCD TV is equipped with LED backlight products estimated rate in 2011 may still only 4.5%, to 2012 may have the opportunity to reach 10%, but is expected to CCFL mercury and the next generation display technology, backlight source, application proportion will continue to affect the LCD TV LED backlight products.

According to MIC data, after Huang Lvguang, red, blue and green, white LED chip development, since the beginning of 1998 application in small size color LCD panel backlight, and gradually the size and scale of inch color LCD panel backlight application development. At present, the main application types are divided into W-LED and RGB-LED. The W-LED hybrid in the package of white light, color saturation is low (NTSC 42%-98%), the mixed light small space, high luminous efficiency (60 lm/W), low power consumption, simple circuit design, the use of a number of small, low power consumption, suitable for the application of IT products with low requirement for color image.

RGB-LED is the three LED hybrid in packages of white light, high color saturation (NTSC 105%-150%), light mixing space, low luminous efficiency (10-60lm/W), high power consumption, complex circuit design, using a more suitable for the high demands of audio-visual products worthy of color application. LED backlight type is divided into the side light type and direct type, side light is placed in the bottom panel or on both sides, with LCD panel smaller with more direct type on the panel, with large area LCD panel is widely used.
