Abstract

The invention discloses a backlight module group which comprises a rubber frame and an optical film. A fixed groove which extends downwards from the upper surface of a frame edge is arranged on the frame edge of the rubber frame, and is provided with a fixed surface which is convexly arranged in the fixed groove. The optical film is provided with a side edge and a positioning lug which convexly extends on the side edge. An elastic fixed part is arranged on the positioning lug corresponding to the fixed groove to be contained in the fixed groove, and supports against the fixed surface in the fixed groove to be fixed in the fixed groove.

Description

【Technical field】 [0001] The invention relates to a backlight module, in particular to a backlight module with an optical film fixing structure. 【Background technique】 [0002] At present, backlight modules have been widely used in LCD TVs, notebook computers, handheld computers, video phones, digital camera display screens and many other electronic products. The liquid crystal display panel itself cannot emit light, and a backlight module (BackLight Module) is generally used to provide it with a uniform and high-brightness light source so that it can display images normally. A general backlight module is mainly composed of light sources, reflectors, light guide plates, various optical films (such as diffusers, prisms, etc.) The structural balance of components is actually one of the problems designers must face. [0003] Please refer to Figure 1A to Figure 1D , which shows the structure and composition relationship of the optical film 8 and the plastic frame 9 in a conve...
