Description

Technical Field

[0001] The utility model relates to the technical field of display modules, and more specifically, to a display module capable of preventing electrostatic shock. Background Art

[0002] In the current display module manufacturing field, flexible printed circuit boards (FPCs) are widely used due to their good flexibility and electrical performance. Usually, after being bent into a specific shape, FPCs are attached to the backlight metal frame to ensure the stability and reliability of the display module. In this process, the gold finger part of the FPC will directly face the backlight metal frame. This design provides convenience in electrical connection, but it also brings some potential problems;

[0003] During the production and transportation process, the backlight metal frame may be affected by static electricity from the external environment. Static electricity is a common phenomenon that may be generated by human operation, equipment friction or other environmental factors. Once static electricity is transmitted to the backlight metal frame, due to its conductivity, static electricity may be further transmitted to the adjacent FPC gold finger. As the electrical connection point between the FPC and the integrated circuit (IC) inside the liquid crystal display (LCD), the gold finger is extremely sensitive to static electricity. When static electricity enters the LCD through the gold finger, it may cause static electricity damage to the IC. Static electricity damage may not only cause the performance of the IC to deteriorate, but may even cause damage to the IC, thereby affecting the normal operation of the entire display module. In addition, static electricity damage may also cause problems such as image distortion and color abnormality in the display module, seriously affecting the user experience. Therefore, we have made improvements to this and proposed a display module that prevents static electricity damage. Utility Model Content

[0023] As described in the background technology, after the FPC is bent into a specific shape, it will be attached to the backlight metal frame to ensure the stability and reliability of the display screen module. In this process, the gold finger part of the FPC will directly face the backlight metal frame. This design provides convenience in electrical connection, but it also brings some potential problems. During the production and transportation process, the backlight metal frame may be interfered by static electricity from the external environment. Static electricity is a common phenomenon that may be generated by human operation, equipment friction or other environmental factors.

The gold fingers are the electrical connection points between the FPC and the integrated circuit IC inside the liquid crystal display LCD, and they are extremely sensitive to static electricity. When static electricity enters the LCD through the gold fingers, it may cause static electricity damage to the IC. Static electricity damage may not only cause the performance of the IC to decline, but may even cause damage to the IC, thereby affecting the normal operation of the entire display screen module.
