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

Abstract

The invention discloses a backlight module, which comprises: a backlight assembly, a backboard, a plurality of frame strips and an assembly. The backplane has a plurality of side walls, the side walls are connected to each other and combined around the backlight, and the top of each side wall has a plurality of grooves. A plurality of frame strips are respectively arranged on the top of the side wall. The bottom surface of each frame bar has a plurality of engaging parts, and the engaging parts of each frame bar are respectively corresponding to the groove body of the corresponding side wall, wherein the engaging parts of each frame bar are respectively inserted into the groove of the corresponding side wall inside the body, and the frame bar slides relative to the side wall, and each engaging piece that drives the frame bar is engaged with one of the side walls of the corresponding groove of the side wall, so that the frame bars are sequentially combined on the side wall, and The frame strips are combined with each other sequentially at the same time to form the gap. The assembly is combined with the two frame strips adjacent to the gap, and is used to cover the top of the side wall together with the frame strips. The backlight module provided by the present invention can make the frame bars easy to assemble and disassemble.

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 by itself, 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 t...
