The future development direction of LED-backlit LCD TV technology

The development trend of future display technology is “high definition, large picture, high picture quality (fast response, high contrast, etc.), energy saving and environmental protection, high color gamut, ultra-thin, intelligent, cheap, etc.” Simply put, “energy saving” The uniformity of image quality, beauty and environmental protection, LED backlight liquid crystal display technology is in line with this development trend.

The response speed of the LED backlight is much larger than the deflection speed of the liquid crystal molecules. The LED backlight can be quickly turned on and off during the deflection of the liquid crystal molecules. The LED backlight control technology can improve the motion smear problem by extinguishing the backlight by timing lighting to achieve high-quality display. Therefore, improving the motion tail is a major development direction of LED backlight control technology.

The color gamut of the LED backlight is higher than that of the CCFL backlight, and the R/G/B LED backlight can reach 100% NSTC or more, so that the LED backlight LCD TV performance is more prominent in terms of saturation and vividness. Therefore, gamut matching has also become a development direction of LED backlight control technology.

The LED backlight is driven by a low voltage constant current, the voltage is easier to control, and the response drive is faster. The control of the backlight is more flexible, and the backlight can be flexibly adjusted according to the ambient light and the remote control command of the LCD TV, so that the human eye can watch the TV more comfortable and improve the fatigue caused by watching the TV for a long time. Therefore, flexible and interactive backlight control is also a development direction of LED backlight control technology.

In short, LED backlight control technology has great potential in LCD TV display. It is believed that LED contrast LCD TVs with high contrast, no motion tailing, high color gamut, high image quality and low power consumption will enter people's lives in the near future.
