Problems solved by technology

A diffuser is introduced into the backlight module. The main function of the diffuser is to provide a uniform surface light source for the LCD display. Usually, the diffuser is fixed by glue. When the frame of the backlight module shrinks, the glue area becomes smaller. This makes the fixing reliability of the diffusion sheet worse, which makes the diffusion sheet very likely to be displaced during the reliability test or in the subsequent use process, thus affecting the display effect of the display

Abstract

The invention discloses a backlight module and a display device, and relates to the field of display technology. The backlight module includes: a substrate; an LED light bar, including a circuit board and a plurality of LED lamps arranged on the circuit board and electrically connected to the circuit board. The circuit board is fixed on the substrate; the LED lamp includes a lampshade and a raised portion fixed on the surface of the lampshade away from the substrate; the light guide plate is located on the first side of the LED lamp, and the LED lamp also includes a first light-emitting surface on the first side. The plane where the light-emitting surface is located intersects the substrate; the diffuser is located on the side of the light guide plate away from the substrate, and includes a hollow part matching the raised part, the hollow part penetrates the diffuser along the thickness direction of the diffuser, and the raised part at least partially penetrates the hollow part . In such a solution, the diffusion sheet is fixed through the cooperation of the raised part and the hollow part, which effectively reduces the possibility of displacement of the diffusion sheet.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a backlight module and a display device. Background technique [0002] As an important part of the liquid crystal display, the backlight module usually uses a light emitting diode (Light Emitting Diode, LED) as the light source, and the backlight module using the LED light source has a relatively thin thickness, which can effectively reduce the thickness of the entire liquid crystal display. The backlight module also has lower energy consumption, therefore, the backlight module using LED as the light source has been widely used. [0003] At present, the penetration rate of LED as a backlight in the field of liquid crystal panel display has exceeded 90%. The backlight module structure mainly has two types: side-type and direct-type. The side-type LED backlight module is to install the LED light source on the side of the light guide plate. and scatter to export ...
