Problems solved by technology
However, this rigid fixing method easily causes the circuit board itself to bend and deform, which in turn damages the components on the circuit board or causes an open circuit problem.
[0003] In addition, the assembled liquid crystal display module cannot provide sufficient cushioning between the liquid crystal backplane and the circuit board due to this rigid fixing method during transportation, thus causing film coating between the circuit board and the liquid crystal backplane. Chip on film (COF) components are damaged due to pulling or wires are broken
[0004] On the other hand, when the circuit board needs to be disassembled from the backplane for heavy work, this method of screw locking is time-consuming to disassemble, and it is easy to accidentally bump into the components around the screw holes and cause damage

The invention discloses a backboard of a liquid crystal display module, an assembly structure of a circuit board and a disassembly and assembly method. The assembly structure comprises a backboard body, a circuit board and an elastic latch, wherein the backboard body is provided with two fixing holes; the circuit board is provided with two opposite surfaces, and one surface is configured on the backboard body; the circuit board is provided with a locating hole and two notches, and the two notches are located at the edge of the circuit board and correspond to the the fixing holes; the elastic latch comprises a locating block and two bayonet locks which are located on a latch body; the locating block passes through the locating holes of the circuit board and leans against the backboard body; the tail ends of the bayonet locks are inserted and clamped in the fixing holes; and the notches of the circuit board lean against the bayonet locks so as to clamp the circuit board between the backboard body and the latch.
Description
technical field [0001] The present invention relates to an assembly structure, and in particular to an assembly structure of a backplane of a liquid crystal display module and a circuit board (ASSEMBLY STRUCTURE OF BACK PLATE AND CIRCUIT BOARD OFLIQUID CRYSTAL DISPLAY MODULE), and its disassembly method and assembly method. Background technique [0002] In the production and assembly process of the liquid crystal display module, the current common circuit board assembly method is to lock the circuit board on the backboard by screws. However, such a rigid fixing method may easily cause the circuit board itself to be bent and deformed, thereby damaging components on the circuit board or causing an open circuit problem. [0003] In addition, the assembled liquid crystal display module cannot provide sufficient cushioning between the liquid crystal backplane and the circuit board due to the rigid fixing method when it is transported, thus causing the film coating between the ci...
