Problems solved by technology

At this time, if the side frame 120 of the backplane is subjected to a force in the x direction, the parts will be displaced, resulting in difficulty or poor assembly
In addition, if the claw structure 120a is designed at the bottom of the backplane side frame 120, since the drawing direction of the plastic injection mold is downward when the backplane side frame 120 is manufactured, it is not easy to form the claw structure 120a, and it must be molded with the sliding of the mold. block structure or change the design of the backplane side frame and other structures, and it is difficult to estimate the number of claw design, causing design troubles
[0006] For example, the fixing methods of the side frame of the backlight module and the backplane of the above-mentioned backlight module all have their insurmountable shortcomings. Therefore, in the existing backlight module assembly technology, there is still an urgent need for a highly reliable and easy-to-assemble backlight module fixing method. Way

Abstract

The invention relates to a back light module which comprises a back plate main body, two back plate side frames, a plurality of lamp tubes, a reflector plate and a diffuser plate, wherein the back plate main body is provided with a bottom surface and at least two first side surfaces. The two back plate side frames are respectively arranged at the two opposite first side surfaces of the back platemain body in opposite direction, wherein each back plate side frame is provided with a bottom surface, a front surface, a back surface, a top surface and two second side surfaces. The front surface is provided with a plurality of lamp tube fixing parts, and each second side surface is provided with at least one buckling claw structure. The lamp tubes are arranged above the back plate main body, the reflector plate is arranged at the bottom of the back plate main body, and the diffuser plate is arranged above the lamp tubes.

Description

technical field [0001] The present invention relates to a backlight module, and in particular to a backlight module with a claw structure and / or an adhesive layer on the frame structure. Background technique [0002] With the progress of science and technology, the technology of the display is constantly developing, and the thin and light flat panel display (Flat Panel Display, FPD) gradually replaces the traditional thick cathode image tube display (Cathode Ray Tube, CRT). Common flat panel displays include plasma displays (Plasma Display Panel, PDP) and liquid crystal displays (Liquid Crystal Display, LCD), which can be widely used in personal digital assistants, notebook computers, mobile phones and televisions. [0003] Taking a liquid crystal display as an example, the liquid crystal display includes a liquid crystal panel and a backlight module. The liquid crystal panel is composed of two substrates and a liquid crystal layer arranged between the two substrates, and t...
