2011LED technology trends: the development of LED backlight and awesome

Discussion on the prospect of LED is due to long life, a commonplace talk of an old scholar, low energy consumption, small volume, fast response and seismic resistance to low temperature and little pollution advantages, its application field is very wide. The next year the Chinese preliminary calculation, power generation LED lighting electricity savings equivalent to the Three Gorges power station throughout the year, at the same time can be reduced to 80 million tons CO2, 650 thousand tons SO2 and 320 thousand tons of NO2 emissions, known as the "history of lighting revolution" is not too much.

The development of semiconductor lighting very quickly. Statistics show that since the birth of the last century in 60s, every ten years, LED costs decreased by ten times and luminous efficiency increased by a factor of ten. And technical progress is always beyond market expectations. Especially in 2008, the Beijing Olympics will give LED a shot in the arm, the opening ceremony of the "dream scroll" to be displayed in the more than 4 thousand and 500 square meters, a single color LED display the largest in the world, when a 45000 LED arrangement of the "fantasy rings" launch, our passion for LED to reach a new high.

In recent years, the LED and the rapid increase in luminous efficiency with low power consumption, environmental protection and other characteristics, expand the products in the traffic lights, drive cars, billboards, lighting and LCD Backlight Market gradually. With the promotion of the Chinese government, semiconductor lighting will soon become a bright industry in china. According to relevant statistics, by 2010, the global LED application market was $50 billion; China LED application market was 60 billion yuan.

Back light LED backlight with high side emitting the most striking, LED as LCD backlight applications, with long service life, high luminous efficiency, no interference and high cost performance, has been widely used in electronic watches, mobile phone, pager, electronic calculator and card machine, with the portable electronic products become small, LED backlight has more advantages, so the backlight production technology will develop to a thin, low power consumption and uniformconsistent aspects. LED is a key device of mobile phone, a mobile phone or PHS about using 10 LED devices, and a color screen and camera equipped mobile phone needs to use about 20 LED devices. At this stage, the amount of backlight is very large, one year to use 3 billion 500 million LED chips. At present, China's mobile phone production is very large, and most of the LED backlight or imported, for domestic LED products, this is a great market opportunity.

From IT's point of view, LED backlight is an important year for development in 2010, LED backlight with mercury free green area, dynamic backlight control, energy saving, low carbon, high ultra-thin streamline appearance color reduction lifelike display has greatly promoted the pace of LED instead of CCFL. Various backlight manufacturers and LED manufacturers to reach a cooperative relationship, together with the proposal, with the latest technology of large size light guide plate. Ultra thin, energy saving and environmental protection, high quality color LED backlight, will become the next strong trend in the development of backlight.

But LED backlight module is not without shortcomings, the power consumption problem is still an important subject for LED backlight module must be overcome. Due to the use of more LED, in addition to power consumption increases, also lead to elevated temperature, and therefore need to increase sensor cooling system to solve this problem, so the thickness is compared with CCFL backlight products more thick.
