　　②Backlight of large-size LCD screen

　　At present, most LCD TV/Monir and lapp LCD screens use CCFL fluorescent tubes as the backlight. Due  unfavorable facrs such as CCFL lifetime and environmental protection, LED backlights are currently being developed. According  the size of the LCD screen, dozens  hundreds of white LEDs are generally required as backlights, and the market potential of its LED driver chips will be great.

　　③Backlight of 7in LCD screen

　　For example, a digital pho frame.

　　④LED flashlight

　　Low-power LED flashlight, strong light LED flashlight, LED miner’s lamp.

　　⑤LED display

　　You can see a variety of LED subtitle displays in buses, subways and various door-front advertising screens, and there are also many large-screen LED dot matrix display screens outdoors, which is a relatively clear super-large screen from a distance. TV set. This requires a dedicated LED display control chip.

　　⑥LED lighting

　　Illumination has passed incandescent and fluorescent lamps, and now the more common energy-saving lamps, the next stage should be the popularization of LED lighting, which requires ultra-high-brightness LEDs. Ultra-long life and extremely low power consumption will be great advantages of LED lights.
