Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of display module FPC, in particular to a new display module FPC with super-long binding positions. Background Art
[0002] As the resolution of display modules increases, the number of driver ICs required to match the display modules will increase accordingly. High-resolution display modules with two touch chips generally use a single-piece FPC plus a one-time ACF binding solution, which will result in a longer binding position and a larger size of the FPC corresponding binding position. In order to facilitate assembly and enhance the flexibility of the bending area, the FPC non-routing area usually needs to be hollowed out.
[0003] In the prior art, punching and hollowing operations are usually performed directly on the non-routing area of the FPC. Although this can achieve the hollowing effect and enhance the flexibility of the bending area, it will also cause the surrounding flatness to deteriorate when the FPC is hollowed out when bent. The PIN pins are likely to be misaligned during ACF binding, resulting in poor product function and material loss. Utility Model Content
[0004] The utility model aims to overcome the above-mentioned shortcomings and provide a technical solution that can solve the above-mentioned problems.

[0006] As a further solution of the utility model: the punching line is designed to be a rectangular structure, and punching waste is generated after the FPC body is punched by the punching line.
[0007] As a further solution of the utility model: after the FPC body is punched, a hollow area is formed on the non-wiring area on its surface, and a layer of reinforcing copper wire is fixed in a ring shape on the inner wall of the hollow area, and the width of the reinforcing copper wire is the same as the depth of the hollow area.
[0008] As a further solution of the utility model: the area of the tape body is larger than the punching line of the rectangular structure, and the tape body is adhered to the surface of the FPC body and the surface of the punching waste.
[0009] As a further solution of the utility model: one side of the glue-tearing handle protrudes from the tape body, and the side of the glue-tearing handle away from the tape body is designed to be an upwardly tilted structure, and the tape body is a single-sided tape.
[0010] As a further solution of the utility model: two bending areas are further arranged on the front side of the FPC body and near the top, and there is a gap between the two bending areas.
[0011] As a further solution of the utility model: the top of the FPC body is bound to the bottom of the display module, and the area of the FPC body is smaller than the area of the display module.
[0012] As a further solution of the utility model: a component binding area is also provided at the bottom of the front side of the FPC body, and a reinforcing sheet is provided at the bottom of the back side of the FPC body.

[0017] 2. After the FPC body is bound, the tape body is torn off and the punching waste is separated from the FPC body, thereby generating a hollow area. The hollow area can effectively enhance the flexibility of the bending area of the FPC body.
[0018] 3. By designing reinforced copper wires on the inner wall of the hollowed-out area, the strength of the FPC body can be effectively enhanced to prevent the FPC body from tearing. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-5 In this embodiment, the punching line 201 is designed to be a rectangular structure, and punching waste 6 is generated after the FPC body 2 is punched by the punching line 201.
[0032] Specifically, before being punched, the punching waste 6 and the FPC body 2 are an integrated structure, and the punching waste 6 is formed after being punched along the punching line 201 .
[0033] See also Figure 2-6 In this embodiment, after the FPC body 2 is punched, a hollow area is formed on the non-wiring area 3 on its surface, and a layer of reinforcing copper wire 7 is fixed in a ring shape on the inner wall of the hollow area. The width of the reinforcing copper wire 7 is the same as the depth of the hollow area.
[0034] Specifically, the hollowed-out area can enhance the flexibility of the FPC body 2 and facilitate subsequent bending, and the reinforcing copper wire 7 is arranged in the hollowed-out area, and the strength of the FPC body 2 can be enhanced by the reinforcing copper wire 7 to prevent the FPC body 2 from being torn from the hollowed-out area.
[0035] See also Figure 1-5 as well as Figure 7-8 In this embodiment, the area of the tape body 501 is larger than the punching line 201 of the rectangular structure, and the tape body 501 is adhered to the surface of the FPC body 2 and the surface of the punching waste 6; one side of the tearing handle 502 protrudes from the tape body 501, and the side of the tearing handle 502 away from the tape body 501 is designed to be an upwardly warped structure, and the tape body 501 is a single-sided tape.
[0036] Specifically, the tape body 501 covers the area outside the punching line 201, which can ensure that the tape body 501 is always bonded to the surface of the FPC body 2 when punching from the punching line 201. When the tape body 501 is not torn off, the tape body 501 is stable on the FPC body 2 and at the same time sticks to the punching waste 6 after punching, which is conducive to carrying the punching waste 6 together after the tape body 501 is torn off. In order to facilitate the grasping of the tearing handle 502, one side of the tearing handle 502 is designed to be a tilted structure, which is convenient for the staff to grasp quickly.

[0040] Specifically, the component binding area 9 can be used to bind other components to the FPC body 2 . A reinforcing sheet 8 made of a stainless steel sheet is also provided on the FPC body 2 to enhance the strength of the component binding area 9 .
[0041] When using:
[0042] First, the tape body 501 is attached to the non-wiring area 3 of the FPC body 2, and the tape body 501 is used to cover the punching line 201 area, and then the FPC body 2 is punched along the punching line 201 (only the layer of the FPC body 2 is punched), thereby generating punching waste 6. Since the punching waste 6 at this time is always adhered by the tape body 501, and the tape body 501 is always bonded to the FPC body 2, the punching waste 6 will not be separated from the FPC body 2 at this time, thereby ensuring that the FPC body 2 As for the overall flatness, after the FPC body 2 is bound, the adhesive tape body 501 can be torn off using the adhesive tearing handle 502, and the adhesive tape body 501 can be used to carry the punching waste 6 and detach it from the FPC body 2, thereby forming a hollow area on the bending area 4 of the FPC body 2. The hollow area can effectively enhance the flexibility of the bending area 4 of the FPC body 2, and facilitate subsequent bending. Finally, a circle of reinforcing copper wire 7 is added to the inner wall of the hollow area to enhance the strength of the FPC body 2 and prevent the FPC body 2 from tearing.
