LCD display module

Abstract

This invention discloses a sort of liquid crystal display die set. It consists of a backboard, a first framing which is laid in this backboard, a second framing which is covered in the first framing, a liquid crystal display panel which is laid in the first framing, a PCB plate which is fixed in the first framing. This first framing has the grab, and this PCB plate has the clip core which corresponds to the grab. This invention adopts the grab orientation configuration to fix the PCB plate, it solves the assemblage problem and the resolving problem of the PCB plate effectively, it predigests the assemblage, and it saves the production time and the manpower cost.

Description

technical field [0001] The invention relates to a liquid crystal display module, in particular to a liquid crystal display module which is easy to fix and disassemble a printed circuit board (PCB). Background technique [0002] A liquid crystal display module ("LCM" for short) generally includes a liquid crystal display panel, a backlight module, and a plurality of frames for fixing the liquid crystal display panel and the backlight module. Referring to Fig. 1, the existing liquid crystal display module includes a liquid crystal display panel 10, a back plate 20, a first frame 30, a second frame 40 and a PCB board 50, and the liquid crystal display panel 10 includes a first substrate oppositely arranged , the second substrate and the liquid crystal layer (not shown in the figure) arranged between the first substrate and the second substrate, the first frame 30 is fixed on the back plate 20, and the second frame 40 covers the first On the first frame 30, the space surrounded...

AI Technical Summary

Problems solved by technology

[0003] The first type of fixing structure is fixed by screws. By opening holes on the PCB board and using screw locks, the PCB board can be effectively fixed, and the PCB board is connected to the metal parts through screws to solve the problem of grounding, but this method requires Increase the cost attached to the screw. If the PCB board is placed on the side of the LCM, it will increase the difficulty of screw locking and increase the working hours of locking. The metal parts need to be designed for tapping; the second fixing structure adopts the form of grounding shrapnel and foam Fixing, in which the grounding shrapnel acts as a grounding function between the PCB board and the metal parts, and the foam is used to fix the PCB board. This method can effectively fix the PCB board, but it increases the cost of the foam and the man-hours for attaching it; the third existing The method is fixed by grounding shrapnel and double-sided tape. This method can effectively fix the PCB board, but it increases the cost of double-sided tape and the man-hours for attaching it. At the same time, it is not easy to disassemble and it is easy to have residual glue.

[0004] The purpose of the above three methods is to effectively fix the PCB board, but it is not easy to assemble and requires additional materials, which consumes assembly man-hours and wastes production costs
