Abstract

The invention provides a backlight module optical film positioning structure. A backlight module comprises a rubber frame and an optical membrane. A plurality of positioning pieces are arranged on the non-light-incoming edge of the optical membrane, parallel to the optical membrane and formed by extending in the direction away from the optical membrane. Positioning grooves are formed in the surfaces, on the same horizontal plane, of the rubber frame and the optical membrane. The side walls of the rubber frame are located on the edges of an optical thin film. Positioning cards are clamped in the positioning grooves. The invention further provides the backlight module and a display.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a backlight module optical film positioning structure, a backlight module and a display. Background technique [0002] At present, liquid crystal display devices have been widely used in various electronic products as display components of electronic equipment. With the development of thinner and lighter electronic products, the frame of electronic equipment is designed to be narrower and narrower. The backlight module is an important part of the liquid crystal display device, and the frame of the backlight module is bound to become narrower and narrower. [0003] The backlight modules in the prior art all include a plastic frame, the light guide plate is surrounded by the plastic frame, and the optical film is fixed on the light guide plate and the plastic frame by light-shielding tape. It can be seen that the plastic frame, as the carrier for the light guide pla...
