Backlight module

Abstract

The invention discloses a backlight module comprising a backlight combination, a back plate, multiple frame strips and an assembly. The back plate is provided with multiple side walls which are connected with each other and surround the backlight combination, and the top of each side wall is provided with multiple groove bodies. The multiple frame strips are installed on the top of the side walls. The bottom face of each frame strip is provided with multiple clamp members which are opposite to the groove bodies of corresponding side walls; the clamp members of each frame strip are installed inside the groove bodies of the corresponding side walls, and the frame strips can slide in relative to the side walls to drive each clamp member of the frame strips to be clamped at one side wall, corresponding to the groove body, of the side walls so that the frame strips can be assembled on the side walls in order, and the frame strips are combined in order with each other to form notches. The combination is combined at two frame strips close to the notch for covering the top of the side walls together with the frame strips. The frame strips of the backlight module of the invention can be assembled and disassembled conveniently.

Description

technical field [0001] The invention relates to a backlight module, in particular to a backlight module with a spliced ​​frame. Background technique [0002] With the increasing development of the electronic industry, flat panel displays have gradually replaced cathode ray tube displays and become the current mainstream. Among the flat panel displays, liquid crystal display (LCD) technology is relatively mature and popular. However, since the liquid crystal display panel of the liquid crystal display cannot emit light, a backlight module is provided under the liquid crystal display panel to provide a light source to achieve the display function. [0003] In current backlight modules, the plastic frame is mostly combined with lateral hooks or slots on the side of the backplane. In detail, several grooves are set on the side of the plastic frame, and several corresponding The hook is assembled and fixed by engaging the groove on the side of the plastic frame with the hook on...

Problems solved by technology

[0004] However, the groove on the side of the plastic frame and the hook on the side of the back plate will have deviations in size during processing. When there is a size deviation between the groove and the hook, it will cause the groove and the hook to not be combined or The combination is too loose and affects the yield of the product

[0005] In addition, it is difficult to disassemble the combined plastic frame and back plate, and the plastic frame and the back plate are easy to produce plastic frame scraps due to mutual friction when they are assembled or disassembled. However, the existence of plastic frame scraps will affect the backlight module. quality of light
