LED Backlighting in The Use Of LCD TVs
May 10, 2022
Using LED as the backlight of LCD TV, the main purpose is to improve the picture quality, especially the color saturation, LED backlight technology display can obtain a wide enough color gamut to make up for the shortcomings of the LCD display device to display the number of colors, so that it can meet or exceed its prescribed color standard requirements, while because of the characteristics of the LED plane light source, so that the LED backlight can also achieve CCFL can not be compared to At the same time, because of the characteristics of LED's flat light source, LED backlight can also realize the color and chroma adjustment function of CCFL, so as to achieve more accurate color reproduction to meet the needs of graphic publishing and graphic design work, and the dynamic adjustment of the screen can make the brightness and contrast can be dynamically corrected when displaying different screens to achieve better picture quality.
LED backlighting for LCD TV sets used when the LCD screen itself does not emit light, the need for backlighting, LED backlighting LCD TV sets use LED light-emitting diodes as the backlight, which has five advantages over cold cathode fluorescent tube backlighting.
First, ultra-wide color gamut, can reach 105% NTSE color gamut, so the colors are more vivid.
Second, ultra-thin appearance, thin to 1.99 cm, more fashionable.
Third, energy saving and environmental protection, energy consumption is 52% lower than the cold cathode backlight, and no cold cathode tube of mercury pollution.
Four, long life, reaching nearly 100,000 hours, can be used for 27 years if open 10 hours a day.
Fifth, can reach 100000:1 ultra-high contrast ratio, higher clarity.
The above performance advantages determine the LED backlight is technically an alternative to cold cathode backlight, the current market price is basically 150% of the cold cathode backlight products. LED backlight itself is optional, the main choice for the whole machine or the choice of technical performance parameters of the LCD panel, such as large physical resolution, dynamic response time, etc., and ordinary LCD TV sets are the same.
