LCD TVs have now entered the lives of thousands of households. Most people know LCD TVs very well, but they don't know much about the accessories in their TVs. So let's take a look at LED backlights today. LED as the backlight of LCD, compared with the traditional backlight technology, in addition to the advantages of the color gamut range, there are many unique advantages, summarized into ten aspects: LED backlights have better color gamut Its color expression is stronger than CCFL backlight, which can make a good complement to the liquid crystal technology with insufficient display color, and the color reproduction is good; LED life can be as long as 100,000 hours Even if it is used continuously for 10 hours every day, it can be used continuously for 27 years, which greatly prolongs the service life of LCD TVs, and has the advantage of overwhelming plasma technology; Large brightness adjustment range It is easy to achieve LED power control, unlike the minimum brightness of CCFL. Therefore, it is easy for the user to adjust the brightness of the display device to the most pleasing state, whether in a bright outdoor or a black room. Perfect moving image The flashing illuminating frequency of the conventional CCFL lamp is low, and the dynamic scene may cause the picture to jump. LED backlight can flexibly adjust the light-emitting frequency, and the frequency is much higher than CCFL, so it can perfectly display the moving picture; Real-time color management Since the red, green and blue colors are independent of each other, it is easy to accurately control the current display color characteristics; Adjustable backlight white balance while ensuring overall contrast When the user's video source is switched between the computer and the DVD player, the white balance can be easily adjusted between 9600K and 6500K without sacrificing brightness and contrast; Provides a continuous array of light sources for large screen sizes LED is a kind of planar light source. The most basic light-emitting unit is a square package with a length of 3 to 5 mm. It is easy to combine into a surface light source with a given area. It has good brightness uniformity, if it is used as a backlight for LCD TVs. Source, the required auxiliary optics can be made very simple, and the screen brightness uniformity is better; Safety The LED uses a low voltage power supply of 5 to 24V, which is very safe, and the design of the power supply module is quite simple; Environmental protection LED light source does not produce any radiation, and there is no toxic substance such as mercury. It can be described as a green light source; Earthquake resistance The planar structure gives the LED a solid internal structure and excellent shock resistance.
