Display module assembly and method for fixing circuit wafer thereof

Abstract

The invention provides a display module assembly and a method for fixing a circuit wafer thereof; wherein, the display module assembly comprises a backboard, at least a fixed component and the circuit wafer; the fixed components are provided with a pair of connecting pieces arranged at the backboard and a pair of fasteners arranged at the connecting pieces; a first distance is kept between the connecting pieces of the fixed components; and the connecting pieces of the fixed components are suitable to deform in a flexible way by means of shortening the first distance. The circuit wafer is provided with at least a fixed hole, the connecting pieces of the fixed components penetrate through one of the fixed holes and the fixed holes are restricted between the fasteners and the backboard of the corresponding fixed components.

Description

Technical field [0001] The invention relates to a method for fixing a circuit board, and in particular to a method for fixing a circuit board of a display module. Background technique [0002] The liquid crystal display module usually 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. See figure 1 , figure 1 Shown is a schematic structural diagram of a liquid crystal display module in the prior art. The existing liquid crystal display module 1 includes a liquid crystal display panel 2, a back plate 5, a plastic frame 4, a front iron frame 3, and a printed circuit board (PCB) 6 , The liquid crystal display panel 2 includes a first substrate, a second substrate, and a liquid crystal layer (not shown in the figure) arranged between the first substrate and the second substrate, and the plastic frame 4 is fixed on the back by a clamping member or the like. On the board 5, the fr...

AI Technical Summary

Problems solved by technology

[0003] At present, the fixing structure of PCB is mostly fixed by screws. By opening holes on the PCB and locking with screws, the PCB can be effectively fixed, and the PCB is connected to the metal parts or the backplane through screws to solve the grounding problem, but this method needs to be increased. The cost of screw locking prolongs the assembly man-hours of the liquid crystal display device and reduces the production efficiency, especially when multiple screws are locked, it is easy to miss the locking screw phenomenon

And even if only a few screws are not locked to the PCB, it will make the PCB not evenly locked to the backplane

This will result in a decrease in product quality, leading to a decrease in yield

In addition, if the PCB board is placed on the side of the LCD module, it will increase the difficulty of screw locking, the metal parts also need to be designed with tapping, and the disassembly and assembly work takes a long time, and it is easy to damage the components

[0004] In addition, if the positioning method of the hook is used to fix the PCB, although this method is more convenient to operate, it may cause electromagnetic interference (Electro Magnetic Interference, EMI), but it also needs to increase the cost of materials to eliminate EMI
