LED backlighting has many advantages compared to CCFL

　　Energy saving: the photoelectric efficiency of the cold cathode lamp is about 60lm/W, while the light efficiency of the commercial LED has reached more than 100lm/W;

　　More environmentally friendly: Toxic materials are used in CCFL manufacturing

　　Making TVs thinner: LED backlighting has changed the mechanical structure design of the TV backlight, significantly reducing the thickness of the light guide plate in traditional backlight sources, making LED backlight TVs thinner. Mobile phone backlight usually requires 4-5 LEDs, while laptop LED backlight requires an average of 45 LEDs; An LED TV requires an average of 500 LEDs. LED backlight has already penetrated into small and medium-sized displays to a certain extent.

　　In mobile applications, 100% use LED backlight; DisplaySearch estimates that the penetration rate of LED backlights in laptops will reach 52% in 2009, and it will rapidly grow to 81% in 2010. The penetration of LED backlight in the field of LCD TV has just begun, but its significance is extraordinary.

　　Development of LED backlight displays:

　　In 2010, it was also known as the "LED Year" by many, and LED backlighting technology quickly became popular, especially in displays

　　Industry. Compared with traditional CCFL backlight, LED backlight has obvious advantages and is more prominent in energy conservation and environmental protection. In today's advocacy of low-carbon consumption, the emergence of LED backlight not only conforms to the trend of the times, but also helps improve the performance of displays to varying degrees. Therefore, it is not surprising that it can be rapidly popularized.
