Description

Technical Field

[0001] The utility model relates to the technical field of display, in particular to a display module for preventing insulating paper from being scratched. Background Art

[0002] In order to avoid radio frequency interference problems on LCD display modules, a copper foil is usually attached above the IC and the FPC. A grounded copper area is added to the FPC and bonded to the copper foil to form an electromagnetic shielding layer. The copper foil is used to solve the radio frequency interference problem. An insulating paper is added between the copper foil and the electronic components on the IC and FPC to prevent the copper foil from contacting the IC and the electronic components and causing a short circuit. The outer surface of the copper foil is also covered with a layer of black insulating paper, such as Figure 1 As shown, after the copper foil is attached to the display module, if the surface insulating paper is rubbed or scratched by foreign objects, the black ink on the surface will easily fall off, resulting in defects and affecting product yield and brand value.

[0003] For example, the Chinese utility model patent (CN217739879U) discloses a backlight module, a touch module and an electronic device, including a backlight assembly, the backlight assembly including an anti-reflection film, a light source, and an iron frame; a flexible circuit board, the flexible circuit board including a first area, a bending area and a second area, the first area of ​​the flexible circuit board being arranged on the mounting surface of the light source; and a protective paper, the protective paper covering the first area and the bending area of ​​the flexible circuit board. The utility model extends the PET protective paper added to the bottom of the backlight front shading glue to the entire bending area of ​​the backlight FPC to prevent breakage, and can also protect the surface of the single-layer area of ​​the backlight FPC to avoid scratches.

[0004] However, when the present inventor implemented this device, he found the following defects: the protection is relatively simple and it is difficult to effectively prevent scratches. Utility Model Content

[0005] Based on this, it is necessary to provide a display module that prevents the insulating paper from being scratched in response to the above-mentioned technical problems. The top transfer film is used for auxiliary attachment. Two positioning holes are designed on the upper end for alignment when the clamp is attached. The material of the transfer film is relatively hard and easy to tear off. The transfer film is designed to be divided into two sections, and a half-punching line is used between the two sections. The half-punching line divides the transfer film into an upper transfer film and a lower transfer film. Before the LCD screen is fully bonded to the cover plate and the backlight is assembled, the copper foil is attached, and then the upper transfer film is torn off along the half-punching line. After the finished product is made, the retained lower transfer film is just on the copper foil area not covered by the cover plate. This lower transfer film can continue to protect the first insulating paper on the surface of the copper foil, and can avoid direct friction and scratching by foreign objects. Before shipping to the end customer or before the end customer uses it, the transfer film is torn off. This design can effectively prevent the insulating paper from being scratched.
