Abstract

The application discloses a backlight module and a display device. The backlight module includes a backplane, a direct-type light source and a cover plate; wherein the direct-type light source is arranged on the backplane, and the direct-type light source is correspondingly divided into a first light source area with a strong light source and a second light source area with a weak light source area; the cover plate is covered and arranged on the direct-type light source, and the cover plate includes a first light-transmitting area and a second light-transmitting area; the first light-transmitting area is set corresponding to the first light source area; The second light-transmitting area is set corresponding to the second light source area; wherein, the luminous flux of the first light-transmitting area is smaller than the luminous flux of the second light-transmitting area. In this way, the display brightness of the display panel can be compensated by the backlight module, so that the display brightness of different display areas of the display panel is uniform, and the display effect of the display device is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display module and a display device. Background technique [0002] A display device generally includes a liquid crystal display panel and a light source module, wherein the light source module is mainly used to provide a surface light source required by the liquid crystal display panel when displaying. Generally speaking, the light source modules can be classified into direct type and edge-lit type according to the position of the light source. For large-sized display devices, the direct-lit backlight is commonly used at present, and the light source is arranged directly below the display panel, while the light source of the edge-lit light source module is arranged on the side of the light source module, which is usually used for smaller-sized backlights. LCD Monitor. [0003] In order to prevent the uneven brightness of the display panel in the display device, gen...
