Problems solved by technology

[0002] In today's display devices (such as liquid crystal display devices, LCD TVs, etc.), there are usually matching differences between the backlight and optical components. It can be conveniently and firmly attached to the PCB board and the LED fixed on the PCB board. The reflector usually has a through hole corresponding to the LED for the LED to be exposed and larger than the LED. At this time, the through hole is in the LED. There will be a PCB board not covered with a reflector around, and the PCB board has a low reflection effect on light, so on the one hand, it can cause the backlight to not be fully utilized; on the other hand, the brightness around the backlight is low, so that The uniformity of the backlight brightness of the display device is reduced, both of which reduce the display quality of the display device

Abstract

The invention discloses a backlight module and a display device. The backlight module comprises PCB fixedly provided with backlight sources and reflection sheets attached to the inner board surfaces of the PCB, wherein through holes for the backlight sources to penetrate through are formed in the reflection sheets, and reflection layers for reflecting light are arranged in gap regions, between the outer edges of the backlight sources and the edges of the through holes, of the PCB. By the adoption of the technical scheme, the utilization rate of the backlight sources and the uniformity of backlight brightness of the display device can be improved, and accordingly the display quality of the display device is improved.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a backlight module and a display device. Background technique [0002] In today's display devices (such as liquid crystal display devices, LCD TVs, etc.), there are usually matching differences between the backlight and optical components. It can be conveniently and firmly attached to the PCB board and the LED fixed on the PCB board. The reflector usually has a through hole corresponding to the LED for the LED to be exposed and larger than the LED. At this time, the through hole is in the LED. There will be a PCB board not covered with a reflector around, and the PCB board has a low reflection effect on light, so on the one hand, it can cause the backlight to not be fully utilized; on the other hand, the brightness around the backlight is low, so that The uniformity of the brightness of the backlight of the display device is reduced, both of which reduce the display qual...
