RGB backlight technology for LED display is a display technology that uses independently controlled red, green and blue (RGB) LEDs as backlight sources to achieve high color gamut, accurate color reproduction and high brightness. The core is to abandon the secondary conversion scheme of traditional white LEDs or blue LEDs + quantum dots, directly emit light through RGB three-color LEDs, reconstruct the display logic from the bottom of the light source, and significantly improve the picture quality.

Core technical features Precise light and color control: Independently drive the three primary color chips to achieve refined color adjustment, so that the color transition of the picture is natural, the contrast between light and dark is delicate, especially in HDR scenes, it can balance the highlights and dark details.

Excellent color gamut and brightness: Directly provide pure primary color light, without the need for filter filtering, the color gamut coverage is far beyond traditional technology, and the peak brightness performance is excellent, and the color saturation can still be maintained at high brightness.

High efficiency and energy saving characteristics: By accurately controlling the light-emitting area, only the LEDs of the required color are activated, which greatly reduces energy consumption, and the energy efficiency is significantly improved compared with traditional display technology.

Optimize visual experience: With the help of local dimming and algorithm compensation technology, the halo phenomenon is reduced, while the side view color decay problem is improved to achieve color consistency under wide viewing angle.

Compared with other technologies, traditional Mini LED does not require a quantum dot conversion layer, has a simpler structure, and has less color distortion;

As an LCD structure upgrade solution, the cost is lower than Micro LED, making it a transitional choice for high-end displays;

The brightness and service life are better than OLED, and the color performance is close to its high-end level.

Currently, it is mainly used in high-end TVs, professional monitors and other fields. Although it faces challenges such as high cost, difficulty in mass production and heat dissipation design, the future integration with AI algorithms and the exploration of new packaging technologies will promote its further popularization in the display industry and lead the industry to develop in the direction of high brightness and precise color.
