Description

Lamp panel and display device Technical Field The application relates to the technical field of display equipment, in particular to a lamp panel and a display device. Background For a traditional liquid crystal display device, a backlight module adopts an LED (Mini LED) as a backlight source, white light is generated through a color conversion material (KSF, YAG, QD and the like), and space debugging of RGB is performed by sub-pixels on a liquid crystal display panel, so that full-color display is realized. With the trend of large screen, users are increasingly pursuing high image quality and low energy consumption. The multi-primary color backlight (such as RGB three-color backlight) is adopted, full color of the backlight can be realized through independent control of primary colors, loss of image signals is reduced, color saturation is improved, and image quality of the liquid crystal display device is improved. Meanwhile, compared with the traditional backlight (Local Dimming), the full-color backlight (Color Local Dimming) can adaptively adjust the backlight based on the image content, and turn off or weaken unnecessary backlight colors at any time, so that the energy saving of the system is realized. The multi-primary color backlight can also be applied to field sequential display, and the light transmittance of the display module can be improved to about 3 times of the original light transmittance due to the fact that the liquid crystal display panel has no filtering function of a color film layer, and the power consumption of the liquid crystal display panel can be effectively and greatly reduced while the image quality is improved. At present, the representation of the multi-primary-color backlight module mainly comprises an RGB three-color backlight module, and a plurality of RGB LED lamp beads distributed in an array are arranged on a lamp panel in the RGB three-color backlight module.
