Background

Among the prior art, display module assembly includes that preceding frame bezel, backlight and shielding back lid EMI cover structure, and above-mentioned structure appears often when the equipment because of the too big vibration abnormal sound that causes in equipment clearance is bad. The vibration abnormal sound is mainly caused by the fact that when the front frame is clamped with the backlight source, an assembly gap exists at the clamping position, the assembly is not in place, for example, the gap is too large, relative movement of the front frame and the back plate can be caused, and the clamping position is in metal-to-metal contact, so that the abnormal sound is generated.
