Abstract

The invention discloses a display module and a display device. The display module comprises a display panel, a backlight, a display scanning circuit and a backlight control circuit. The display panelincludes an array of pixels, the array of pixels includes P pixel partitions, each pixel partition includes a plurality of display pixels; the backlight includes a light emitting array, the light emitting array includes P light emitting regions, each light emitting region includes a plurality of light emitting units, wherein the x-th light emitting region provides a light source to the x-th pixelregion; the display scanning circuit is used for sequentially scanning P pixel partitions. The backlight control circuit is configured to turning on the light emitting unit in the y+1 th light emitting partition when the display scanning circuit scans the y th pixel partition, and to turn on the light emitting unit in the first light emitting region when the display scanning circuit scans the p thpixel partition. The invention can improve the display contrast and reduce the smearing problem at the same time.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display module and a display device. Background technique [0002] The liquid crystal display device includes a liquid crystal display panel and a backlight source. The electric field between the pixel electrode and the common electrode in the liquid crystal display panel can deflect the liquid crystal molecules. After the liquid crystal molecules are deflected, the light source generated by the backlight assembly will pass through the liquid crystal display panel. The size of the electric field can make the liquid crystal molecules deflect in different degrees, and when the liquid crystal molecules are deflected in different degrees, the light transmittance of the liquid crystal display panel is different, and the amount of light transmitted by the backlight of the liquid crystal display panel is different, thereby realizing the display of images .
