dvantages

LED as the backlight source of LCD, compared with traditional backlight technology, in addition to the advantages in the color gamut, there are many unique advantages, which can be summarized into ten aspects:

1) The LED backlight has a better color gamut. Its color expression is stronger than that of CCFL backlight, which can make up for the lack of liquid crystal technology in the number of display colors, and the color reproduction effect is better.

2) The service life of the LED can be as long as 100,000 hours. Even if it is used continuously for 10 hours a day, it can be used continuously for 27 years, which greatly extends the service life of the LCD TV.

3) The brightness adjustment range is large. It is easy to achieve LED power control, and there is a threshold for the minimum brightness of CCFL. Therefore, it is easy for users to adjust the brightness of the display device to the most comfortable state, whether in a bright outdoor or a dark indoor.

4) Perfect motion picture. Traditional CCFL lamps have a low flicker and light emission frequency, which may cause screen jumps when performing dynamic scenes. The LED backlight can flexibly adjust the luminous frequency, and the frequency is much higher than that of the CCFL, so it can perfectly present the motion picture.

5) Real-time color management. Since the red, green and blue are illuminated independently, it is easy to accurately control the current display color characteristics.

6) Adjustable backlight white balance, while ensuring overall contrast. When the video source is switched between the computer and the DVD player, the user can easily adjust the white balance between K and K without sacrificing brightness and contrast.

7) It can provide continuous area array light source for large screen. LED is a flat light source. The most basic light-emitting unit is a square package with a side length of 3 to 5 mm, which can be easily combined to form a surface light source of a predetermined area, with good brightness uniformity. If used as the backlight source of an LCD TV, the required auxiliary optical components are relatively simple, and the screen brightness uniformity is even better.

8) Safety. The LED uses a low voltage power supply of 5~24V, which is very safe, and the design of the power supply module is also quite simple.

9) Environmental protection. The LED light source does not produce any rays or toxic substances such as mercury. It can be described as a green and environmentally friendly light source.

10) Anti-seismic. The planar structure allows the LED to have a stable internal structure and excellent seismic performance.

Compared with CCFL backlight, what are the advantages of LED backlight?

Energy saving and environmental protection

Compared with traditional CCFL backlight, LED backlight can save energy by more than 40% compared with general CCFL backlight of the same specifications and civil grade products, which greatly improves energy saving. In addition, the mercury in the CCFL backlight is a substance that is quite harmful to the environment, but the LED backlight does not contain this harmful substance, which is more conducive to environmental protection.

Lightweight and elegant

The LED backlight is composed of many grid-shaped semiconductors, and each "grid" has an LED semiconductor, so that the planarization of the light source can be successfully realized. The planarized light source not only has excellent brightness uniformity, but also does not require complicated optical path design. In this way, the thickness of the LCD can be designed to be lighter and thinner, while still having higher reliability and stability.

The traditional CCFL is a tubular light source, and it requires quite complicated auxiliary components to evenly distribute the light emitted by it to every area of the panel. The thickness of the screen is also difficult to control, and as the panel increases, multiple light sources must be used, which further increases the complexity and cost of the design. For example, for LCD or TV products over 50 inches, the cost of direct-lit CCFL backlight modules may account for more than half of the cost of the panel.

Ultra wide color gamut

The LED backlight has the characteristics of more uniform light emission, and is far better than the CCFL backlight in terms of color expression. It can make up for the lack of display colors in LCD technology, and easily achieve a wide color gamut of NTSC118% or higher, allowing the LCD display to truly restore the vivid colors in the colorful nature.

The traditional CCFL backlight technology, due to the limitation of fluorescent material, the red light rendering ability of the tube is weak, and the color mixing effect of the matched color filter is also poor, which can only achieve NTSC 65-75% of the NTSC color area. Even through the use of an improved CCFL light source, it can only achieve a color gamut of about 90% of the NTSC equivalent ratio, which affects the image quality.

Long service life

The service life of the LED backlight can be as long as 100,000 hours, even if it is used continuously for 10 hours a day, it can be used continuously for 27 years. Therefore, the use of LED backlight LCD or LCD TV after a long time of use, the brightness attenuation of the backlight is better than the CCFL backlight.

The service life of ordinary CCFL backlight is about 25,000 hours, and the luminous life of the latest top CCFL backlight is only 60,000 hours. At the end of its life, the brightness of the LCD will drop significantly, and users have to replace the CCFL backlight module of the LCD. The LED backlight does not have such a problem at all. At this stage, the actual service life of the white LED backlight is 50,000 to 100,000 hours, which is basically the same as the service life of the LCD display, and there is the potential for further improvement. Even if it is used 24 hours a day, it is enough for 5 years. Therefore, the luminous life of LED backlight far exceeds that of CCFL backlight.
