In terms of the cost of LED backlight and traditional CCFL backlight, today, when LED backlight technology has become the mainstream, it has been recognized by consumers with many advantages such as mercury free, low energy consumption, good color and long service life. At the same time, the cost of small-size LED backlight has gradually decreased to a price very close to that of CCFL backlight. For consumers, having an energy-saving, environment-friendly and affordable product will naturally be sought after by consumers.

With its unique and overwhelming advantages, LED backlight technology gradually shows a strong application prospect. Next, let's analyze the ten leading advantages of LED backlight technology:

1) LED backlight has better color gamut. Its color expressiveness is stronger than that of CCFL backlight, which can make up for the insufficient number of display colors, and the color restoration effect is better.

2) The service life of LED can be up to 100000 hours. Even if it is used continuously for 10 hours a day, it can be used continuously for 27 years, which greatly prolongs the service life of LCD TV and obtains an overwhelming advantage over plasma technology.

3) Large brightness adjustment range. It is easy to realize LED power control. Unlike the minimum brightness of CCFL, there is a threshold. Therefore, it is easy for users to adjust the brightness of the display device to the most pleasing state, whether outdoors or indoors.

4) Perfect motion picture. The flickering frequency of traditional CCFL lamp is low, which may cause picture jumping when representing dynamic scenes. The LED backlight can flexibly adjust the luminous frequency, and the frequency is much higher than CCFL, so it can perfectly present the moving picture.

5) Real time color management. Because the red, green and blue three colors emit light independently, it is easy to accurately control the current display color characteristics.

6) The backlight white balance can be adjusted while ensuring the overall contrast. When the user's video source is switched between the computer and DVD player, the white balance can be easily adjusted between 9600k and 6500k without sacrificing brightness and contrast.

7) It can provide continuous area array light source for large-size screen. LED is a planar light source. The most basic light-emitting unit is a square with a side length of 3 ~ 5mm. After packaging, it is very easy to be combined into a surface light source with a given area, with good brightness uniformity. If it is used as the backlight of LCD TV, the required auxiliary optical components can be made very simple, and the brightness uniformity of the screen is better.

8) Safe. Led uses 5 ~ 24V low-voltage power supply, which is very safe, and the design of power supply module is quite simple.

9) Environmental protection. LED light source has no radiation and no toxic substances such as mercury. It is a green light source.

10) Earthquake resistance. The planar structure makes the LED have a stable internal structure and excellent seismic performance.
