Embodiment Construction

[0075] In order to avoid the above-mentioned problems in the prior art, the present invention designs an elastic tenon between the front frame and the back plate of the display module to provide a good fixing effect for the circuit board of the display module. The good elasticity of the elastic tenon can provide the shock absorbing effect of the display module, so that the flexible circuit board arranged between the circuit board and the display panel will not be pulled and damaged during the process of carrying the display module. In addition, through the configuration of the elastic tenon, the display module can have a slight gap between the front frame and the circuit board, so as to avoid the problem of short circuit caused by the chips on the circuit board contacting the front frame. Furthermore, the elastic tenon can have different types of changes, and the assembler can choose according to the actual design and demand, so as to make the assembly process smoother. A numb...

Abstract

The invention relates to a display module which comprises a back board, an adhesive frame, a circuit board, a front frame and an elastic tenon. The back board comprises an optical film placing part and a lateral wall. The adhesive frame comprises a lateral wall fixed part arranged on the lateral wall and a panel placing part arranged on the optical film placing part. The circuit board is arranged on the lateral wall fixed part; and the front frame is arranged on the lateral wall and the faceplate placing part. The elastic tenon comprises a bottom part, a penetrating part and a top part, wherein, the bottom part is arranged on the lateral wall. The penetrating part penetrates the lateral wall fixed part and the circuit board in sequence; and the top part is in contact with the front frame. The invention further provides an assembling method of the display module, so as to provide more convenience and a highly-reliable assembling manner for the display module.

Description

【Technical field】 [0001] The present invention relates to a display module and its assembly method, and in particular to a highly reliable display module and its assembly method. 【Background technique】 [0002] Generally speaking, a display module is composed of a display panel (Display Panel), a circuit board and a backlight module (Back Light Module). The backlight module is located on one side of the display panel and is used as a backlight source for the display panel. The circuit board is electrically connected to the display panel through the flexible circuit board, so that it can be arranged on the side or the back of the backlight module to save assembly space. [0003] Common methods for fixing the circuit board in the backlight module include hook fixing and screw locking. Fixing the circuit board with hooks has the advantage of being easy to assemble, but in the process of transporting the display module, the display panel may be deformed or displaced due to sha...
