The Competition Market Of LED Backlight

  The discussion on the prospects of LED backlights is a commonplace. Due to its long life, low energy consumption, small size, fast response, anti-seismic resistance to low temperature, and low pollution, its application fields are extremely broad. According to preliminary calculations, the annual energy saved by LED lighting in China is equivalent to the annual power generation of the Three Gorges Power Station. At the same time, it can reduce the emissions of 80 million tons of CO2, 650,000 tons of SO2 and 320,000 tons of NO2, which is called "the history of human lighting." The revolution is not an exaggeration.

According to the G3 comprehensive report: From the perspective of IT, LED backlight is an important year for development in 2010. LED backlights are based on mercury-free green, environmentally-controlled backlights, low-carbon energy-saving, ultra-thin streamline appearance, and high The advantages of color reproduction and realistic display have greatly promoted the pace of LED replacement for CCFL. Each of the backlight manufacturers and the LED backlight manufacturers reached a cooperation relationship, jointly proposed a solution, combined with the latest technology of large-size light guides. Ultra-thin, energy-saving, environmentally-friendly, high-quality LED backlights will surely become the next strong trend in backlight development.

However, LED backlight modules are not without drawbacks. The problem of power consumption is still an important issue that LED backlight modules must overcome. Due to the use of more LEDs, in addition to increasing power consumption, it also causes temperature rise. Therefore, it is necessary to increase the cooling system and the sensor to solve this problem, so it is thicker than the product using CCFL backlight. .

The development of semiconductor lighting is very rapid. Statistics show that since the birth of the 1960s, every ten years, LED costs have dropped tenfold and luminous efficiency has increased tenfold. And technical progress has always exceeded market expectations. Especially in 2008, the Beijing Olympic Games gave LED another shot of stimulant. The “Dream Long Roll” on the opening ceremony was displayed in more than 4,500 square meters, which is the largest single-color LED backlight in the world. When the "Dream Five Rings" made up of LEDs were launched, the enthusiasm of the Chinese people for LED reached a new high.
