[0002] Liquid crystal display devices are widely used in various information, communication and consumer electronic products. Liquid crystal display modules are mainly composed of liquid crystal display screens and backlight modules. The liquid crystal display screen is usually bound with an FPC, which is bent to the back of the backlight module and connected to the connector. The FPC is in direct contact with the backlight iron frame on the back of the backlight module.

[0003] In the current module structure, in order to prevent the gold finger of the FPC plug-in terminal from directly contacting the backlight iron frame, which would cause the gold finger to be damaged by static electricity, a piece of black insulating paper is usually added to the back of the backlight module corresponding to the position of the gold finger of the FPC plug-in terminal, which can effectively improve the problem of electrostatic damage to the gold finger. However, as the customer's FPC structure changes, the position of the FPC plug-in terminal also changes, which means that the position of the black insulating paper on the backlight must also change synchronously. Such changes will increase costs and are not very economical. Utility Model Content
