Backlight module and display device

Abstract

The invention provides a backlight module and a display device. The backlight module comprises at least two optical structures, a rubber frame and a fixing part, wherein a positioning convex lug which extends outwards is arranged at the edge positions of the at least two optical structures; the rubber frame is arranged on the peripheries of the at least two optical structures, a positioning notch is formed in the position, corresponding to the positioning convex lug, of the rubber frame, and the positioning convex lug is inserted into the positioning notch; the fixing part is arranged in the positioning notch and used for fixing the positioning convex lug into the positioning notch. The positioning notch is formed in the rubber frame, the positioning convex lug of the optical structures such as an optical film material and a diffuser plate is inserted and fixed into the positioning notch through the fixing part, fixation of the optical film material and the diffuser plate can be achieved without the need of a sheet guide in the fixing mode, the widths of the positioning convex lug on the optical film material and the diffuser plate can be reduced, and therefore the width of the frame of the backlight module is reduced and the structural design of a super-narrow frame is achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] The backlight module is one of the important devices in the liquid crystal display. The direct-type backlight module mainly includes light source, optical film material, diffusion plate, plastic frame, back plate and other components. The light is emitted from the light source in the backlight module. After being reflected by the reflective sheet on the back panel, it directly shoots into the diffuser plate on the screen, and then shoots into the screen through the diffuser plate. [0003] In the traditional direct type backlight module, the fixing method of the optical film material and the diffusion plate is as follows: [0004] A positioning column (Sheet Guide) is provided on the plastic frame or the back plate, and a positioning gap is opened on the edge of the diffusion plate corresponding to the posit...

AI Technical Summary

Problems solved by technology

[0005] This method of fixing the optical film and the diffusion plate adopts the adhesive tape method. It is necessary to reserve enough space on the plastic frame or the back plate to set the positioning column, which will increase the width of the positioning lugs on the optical film and the diffusion plate. , thus increasing the width of the frame of the backlight module, and the structural design of the ultra-narrow frame cannot be realized
