In fact, LED corny discussion of prospects, due to long life, low energy consumption, small size, fast response, shock resistance and low temperature, pollution and other prominent advantages, its applications is extremely broad. Preliminary calculations, the future use of LED lighting in China each year of electricity savings equivalent to annual power generation of Three Gorges power station, at the same time reducing 80 million tons CO2, 65 million tons SO2 and NO2 emissions of 32 million tons, called "the history of mankind lighting revolution "is not an exaggeration.
Very rapid development of semiconductor lighting.Statistics show that 60 years since the inception of the last century, every decade, LED lower cost ten times ten times the luminous efficiency.And technical progress on market expectations are always exceeded.In recent years, LED rapid increase in luminous efficiency and has low power consumption, environmental protection and other features, the lead product in the traffic signals, automotive, outdoor signage, LCD backlighting and other lighting and gradual expansion of the market. With the Chinese government to promote, semiconductor lighting will soon become a bright industry.According to the U.S. authorities predict that by 2010, the global LED application market is 500 billion; LED application market in China was 600 billion yuan.
Efficient LED backlight LED backlight side of the most spectacular, LED as LCD backlight applications, has a long life, high luminous efficiency, no interference, and cost performance characteristics, has been widely used in electronic watches, cell phones, BP machines, electronic calculator and credit card machines, with the increasing miniaturization of portable electronic products, LED backlight advantages, so backlight production technology will be more thin, low power consumption and develop uniform.LED key components in the mobile phone, a common use of mobile phone or PHS is about 10 LED devices, and with a color screen and camera phones will need to use about 20 LED devices. The amount of current mobile phone backlight is very large, 3.5 billion a year to use LED chips. At present a large amount of mobile phone production in China, and most LED backlight or imported, for domestic LED products, this is a great market opportunity.
From the IT point of view, LED back light source is an important year for development in 2010, LED backlight with green mercury-free, regional dynamic backlight control, low-carbon energy, ultra-thin streamline appearance, high fidelity color reproduction of display, etc., greatly promoted the pace of LED instead of CCFL. LED backlight makers and manufacturers in all a partnership, co-sponsored programs, and large-size LGP with the latest technology. Thin, energy saving, high-quality color LED backlight, backlighting will become the next developed a strong trend.
However, LED backlight module is not without shortcomings, power consumption remains a LED backlight module an important issue that must be overcome.As a result of more of the LED, in addition to increased power consumption, but also cause temperature problems and, therefore, must increase the cooling system and sensors to solve this problem, and therefore appear more on the thickness of the product with more thick CCFL backlight.
Although there are many advantages of LED backlighting, but its also has a wider application of unavoidable difficulties, first of all, the application of this new technology products is not an edge in price, addition, LED technology rests in the hands of the few manufacturers create difficulties for its popularity, the last reason is the technology itself, LED backlighting technology in LED efficiency, and heat on the current control is not doing well in the long term trend, LED backlighting technology as a replacement-type technology products that are sure to proliferate slowly, and according to related industries expected that this large area applications should be in 2008. Of course with the Samsung, LG's new panel technology's rapid development, may also be ahead of its large area application.
