Abstract

The invention relates to a backlight module and a display device. The backlight module comprises a backplate, a convex rib structure, a supporting lug boss, a circuit board, a covering film, an adhesive layer, an adhesive frame and a frame. The backplate is provided with a front surface and a rear surface. The rear surface is provided with a circuit board placing area. The convex rib structure is positioned on the periphery of the circuit board placing area; and the surface of the top part of the convex rib structure is provided with an adhesion area. The supporting lug boss is positioned inside the circuit board placing area. The circuit board is positioned inside the circuit board placing area, is supported by the supporting lug boss and is limited to move in the X direction and the Y direction by the convex rib structure positioned on the periphery of the circuit board placing area. The covering film covers the circuit board and the convex rib structure so as to limit the movement of the circuit board in the Z direction. The adhesive layer is positioned between the covering film and the adhesion area of the convex rib structure. The adhesive frame is positioned on the side of the backplate. The frame is positioned on the outer side of the adhesive frame. The invention also provides a display device with the backlight module.

Description

technical field [0001] The present invention relates to a backlight module and a display device, and in particular to a backlight module and a display device with a simpler circuit board fixing method. Background technique [0002] With the development of the industry, digital tools such as mobile phones, digital cameras, digital video cameras, notebook computers and desktop computers are all becoming more convenient, multi-functional and beautiful. direction of development. When using these information products, the display screen is an indispensable human-machine communication interface, and the display screen of the above-mentioned products will bring more convenience to the user's operation. Among them, liquid crystal display devices have become the mainstream of display screens. However, since the liquid crystal display panel of the liquid crystal display device cannot emit light, a backlight module must be provided under the liquid crystal display panel to provide a ...
