Problems solved by technology

Therefore, this method consumes a lot of manpower, wastes time, and the efficiency is not high.
[0012] In addition, each optical film needs to be cut several times (for example, three times) before it can be cut into the required size, which also increases the manufacturing cost and man-hours.

Abstract

The invention relates to a backlight module, a display device and a manufacturing method of a diffusion sheet. The backlight module comprises a light guiding plate and a plurality of optical membrane sheets, wherein the light guiding plate is provided with a light-emitting surface, the optical membrane sheets are arranged at one side of the light-emitting surface, each optical membrane sheet comprises the diffusion sheet and a prism sheet, the diffusion sheet is integrally molded and comprises an upper diffusion sheet and a lower diffusion sheet, and the diffusion sheet is bent, so that the upper diffusion sheet and the lower diffusion sheet are parallel and opposite and form a containing space; and the prism sheet is clamped in the containing space. The upper diffusion sheet and the lower diffusion sheet of the backlight module are integrally molded, and when the optical membrane sheets are assembled, the prism sheet is clamped in the diffusion sheet by bending the diffusion sheet. The design can prevent the optical membrane sheet in a traditional backlight module from tripping, also can avoid material mixing when in assembly, simplifies the assembling working procedure and improves the production efficiency.

Description

technical field [0001] The invention relates to a manufacturing method of a backlight module, a display device and a diffusion sheet, in particular to a backlight module and a display device in which an upper diffusion sheet and a lower diffusion sheet are integrally formed, and a prism sheet is clamped in the diffusion sheet. Background technique [0002] Among various image display devices, liquid crystal displays have been widely used in various devices due to their advantages of light weight, small size, low power consumption, and no radiation. Liquid crystal display can be divided into two parts, one is the backlight module, which can provide stable and uniform light; the other is the liquid crystal panel (mainly composed of two substrates sandwiching the liquid crystal layer), which is located Where the light is emitted, the direction of the light in the liquid crystal panel is changed by controlling the rotation of the liquid crystal molecules in the liquid crystal pa...
