Abstract

The invention relates to the technical field of display, and particularly discloses a backlight assembly, a display panel and a display device.The backlight assembly comprises a backlight source and a dimming piece, the backlight source comprises a plurality of light source units arranged in a matrix mode, the dimming piece is arranged on the light emitting side of the backlight source, and the dimming piece comprises a plurality of adjusting units arranged in a matrix mode; each light source unit at any position is used for emitting backlight to the first sub-pixel set matched with the light source unit, and each adjusting unit at any position covers the light incident side of the second sub-pixel set matched with the adjusting unit; the first sub-pixel set of each light source unit and the second sub-pixel set of each adjusting unit at the corresponding sorting position do not coincide with each other and have intersection sub-pixels, so that the problem of light leakage is solved, and the display effect is improved.

Description

technical field [0001] The present application generally relates to the field of display technology, and in particular, discloses a backlight assembly, a display panel and a display device. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) module is usually composed of an LCD panel and a backlight, wherein the backlight is responsible for providing a light source to the LCD panel for the LCD panel to display images. Local dimming technology refers to the technology in which the backlight source adjusts the brightness of the corresponding area to different degrees with the brightness of the displayed image in each area of ​​the LCD panel; local dimming technology can help LCD to improve dynamic contrast and improve image quality and lower power consumption. [0003] The local dimming technology is limited by the number of its own partitions, so that each partition of the local dimming technology and the sub-pixels in the LCD panel are not c...
