LED back light technology, with its unique, overwhelming, gradually shows powerful application prospect of the digital signage, splicing screen display industries has been widely used. Why the LED backlight technology widely used in display market?
LED backlight technology is widely used in the display market, mainly reflected in the following ten big advantage.
1, color expressive
Its expressive than CCFL back light colors, but shortage of display color LCD technology have very good cover effect, color reduction effect is better.
2, long service life
LED the service life of up to 100000 hours, even though the continuous use of 10 hours a day, can also be used for 27 years in a row, greatly extend the service life of the LCD TV, overwhelming advantage of plasma technology can be obtained.
3, large range of brightness adjustment
LED power control is easy, unlike the minimum brightness CCFL is a threshold. Therefore, no matter in the bright outdoor or indoor all black, users are easy to adjust the brightness of the display device to the most pleasing to the eye.
4, moving picture perfect
Traditional CCFL tube twinkle light frequency is low, performance dynamic scene images may be produced. LED backlight can adjust the light frequency, flexible and frequency and much higher than the CCFL, so perfectly present motion picture.
5, color management in real time
Due to red, green and blue three colors independent light, easy to precisely control the display color feature.
6, can adjust the backlight white balance, at the same time, guarantee the overall contrast
When a user video source when switching between the computer and DVD player, can easily adjust the white balance between 9600 k and 6500 k, and will not sacrifice the brightness and contrast.
7, can provide large size screen with continuous array light source
LED is a kind of planar light source, the most basic lighting units is 3 ~ 5 mm on each side of the square after encapsulation, extremely easy to together to established area in front of the light source, has the very good brightness uniformity, if as back light liquid crystal TV, the auxiliary optical components can be done is very simple, the screen brightness uniformity.
8, security,
LED is used 5 ~ 24 v low voltage power supply, very safe, the design of the power supply module is simple.
9, the environmental protection
LED light source produced no rays and there was no toxic substances such as mercury, is a green light.
10, seismic
Planar structure make leds have a solid internal structure, seismic performance is excellent.
It is with these high quality advantage, LED technology has been widely used in the display industry.
