Abstract

The invention belongs to the field of liquid-crystal display, and discloses a novel side light type back light module assembly structure. At least two holes which are adapted through connecting columns are respectively arranged at intervals in a horizontal direction at the top parts of a liquid crystal panel, a first diffusion barrier or a polarization brightness enhancement film, a prism sheet, a second diffusion barrier, a light guide plate and a reflecting film; the connecting columns sequentially pass through each hole; and a front window frame and a back plate of a frame form a supporting framework through connecting columns at the upper parts. By using the assembly structure of the invention, all optical components can be uniformly under stress, naturally stretch by self gravity and can freely move on the surfaces of the connecting columns after temperature distortion, thereby avoiding the thickness limit of optical components on the back light module, simplifying an assembling structure and preventing the generation of deformation and moire; and simultaneously, the invention can also achieve the efficacies of saving space, maintaining the appearance integrity and increasing the overall strength, thereby being more practical.

Description

technical field [0001] The invention belongs to the field of liquid crystal display, and in particular relates to a novel side-light type backlight module assembly structure. Background technique [0002] The backlight module is the main part of the liquid crystal display. In the prior art, it is widely used to fix various optical film materials by buckling on the side, such as figure 1 As shown, 101 is the buckle of the optical part in the conventional module; 102 is the backplane connection column of the conventional module. [0003] Backlight modules using side buckles in the prior art require optical components to have sufficient thickness; in this way, thermal expansion and deformation and uneven force deformation are more likely to occur, resulting in display defects such as wavy light and dark, which seriously affect Video viewing effect. [0004] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0005] In view of the ...
