Abstract

The invention discloses a membrane positioning structure, a backlight module with the membrane positioning structure and a display device. The membrane positioning structure comprises a back plate, a positioning part and a membrane. The positioning part is attached to the inner end face of the vertical edge of the back plate and is provided with a protrusion, the membrane is provided with a positioning hole fitted with the protrusion, and the positioning hole matches with the protrusion to position the membrane. The positioning part of the membrane positioning structure is attached to the inner end face of the vertical edge of the back plate, the protrusion on the positioning part matches with the positioning hole to position the membrane, the positioning structure is completed at the edge of the back plate, occupied space is small, shape of light guide plate is not influenced, and a notch need not be arranged on the light guide plate for avoiding. The vertical edge of the back plate is purely erected without any deformation, thickness of a space occupied by the vertical edge of the back plate is reduced to smallest, namely size of thickness of the vertical edge only, and narrow-edged development of a liquid crystal display television is facilitated.

Description

technical field [0001] The invention relates to a diaphragm positioning structure of a backlight module, and a backlight module and a display device having the diaphragm positioning structure. Background technique [0002] The backlight module is mainly composed of light source, reflector, optical film, light guide plate, back plate and other related components. The main function of the optical film with prism structure is to condense light. Some types of optical brightening film and polarizer can reflect, recycle and reuse the polarized light that cannot pass through the polarizer to improve the effective utilization of light. This requires that the positioning and installation of the optical diaphragm be accurate, and the installation accuracy is high. [0003] At present, during the assembly process of the backlight module, the positioning of the optical film is done by the rivet posts on the back plate. The method of positioning the diaphragm by the rivet column takes ...
