Abstract
Description
Technical Field
[0001] The utility model relates to the field of display screen modules, in particular to an FPC pre-bending structure and a display module. Background Art
[0002] As the devices used for display modules become more and more sophisticated, the space for housing assembly is very limited. Therefore, when assembling the display module, the FPC needs to be folded at a specific angle in advance before it can be successfully installed in the device. Since the FPC is relatively soft and flexible, it is difficult to bend the FPC to a specific angle during assembly, resulting in difficulty in assembling the display module and low production efficiency.

[0010] In one of the embodiments, a bending-resistant ink is provided on the pre-bending line.
[0011] In one embodiment, the bending-resistant ink is insulating ink.
[0012] In one embodiment, the pre-bent sheet is rectangular in shape.
[0013] In one embodiment, a first reinforcing sheet is disposed on a side of the FPC body away from the first connection area, and a second reinforcing sheet is disposed on a side of the FPC body away from the second connection area.
[0014] In one embodiment, a display module includes the above-mentioned FPC pre-bending structure.
[0015] Compared with the prior art, the utility model has at least the following advantages:
[0016] The FPC pre-bending structure of the present invention arranges a pre-bending sheet on the surface of the FPC, and uses a silk screen process or a half-punching line process to produce a pre-bending line on the pre-bending sheet, so that the installer can use the pre-bending line as a bending reference when installing the display module. In the present embodiment, the material of the pre-bending sheet is a copper sheet, and the copper sheet's easy-to-bend, non-breakable and non-rebounding properties are utilized to achieve the pre-bending of the FPC at a preset specific angle. As a result, the installer can complete the assembly operation more conveniently, greatly improving the production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
[0017] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings required for use in the embodiments are briefly introduced below.
[0018] Figure 1 Schematic diagram of an FPC pre-bending structure in an embodiment of the present invention.
[0019] Description of the drawings: 10, FPC; 100, first connection area; 200, second connection area; 300, bending area; 310, pre-bending sheet; 311, pre-bending line; DETAILED DESCRIPTION
[0020] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.
[0021] See also Figure 1 A FPC pre-bending structure includes: an FPC10 body, the FPC10 body includes a first connection area 100, a second connection area 200 and a bending area 300, the first connection area 100 is arranged at one end of the FPC10 body, the second connection area 200 is arranged at the other end of the FPC10 body, the bending area 300 is arranged on the surface of the FPC10 body, a pre-bending piece 310 is arranged on the bending area 300, and a pre-bending line 311 is arranged on the pre-bending piece 310.
[0022] It should be noted that by providing a pre-bending sheet 310 on the surface of the FPC 10, and using a silk screen process or a half-punching line process to produce a pre-bending line 311 on the pre-bending sheet 310, the installer can use the pre-bending line 311 as a bending reference when installing the display module. In the present embodiment, the material of the pre-bending sheet 310 is a copper sheet, and the copper sheet's characteristics of being easy to bend, not easy to break, and not easy to rebound are utilized, so that the FPC 10 can be pre-bent at a preset specific angle. As a result, the installer can complete the assembly operation more conveniently, greatly improving production efficiency.
[0023] In one embodiment, a protective film is provided on the side of the pre-bent sheet 310 away from the FPC 10. This arrangement prevents the pre-bent sheet 310 from being worn, so that the pre-bent sheet 310 maintains good performance.
[0024] In one embodiment, a protective adhesive layer is provided on a side of the pre-bent sheet 310 close to the FPC 10, and the pre-bent sheet 310 is bonded to the FPC 10 through the protective adhesive layer. In addition, the edge of the protective adhesive layer is extended outward relative to the edge of the pre-bent sheet 310 to encapsulate the edge of the pre-bent sheet 310, thereby preventing the edge of the pre-bent sheet 310 from scratching the FPC 10 and causing the loss of function of the FPC 10.
[0025] Please refer again Figure 1 In one embodiment, a bending-resistant ink is provided on the pre-bending line 311, so that the pre-bending line 311 area on the FPC 10 is strengthened, thereby improving the service life of the FPC 10.
[0026] Preferably, the bending-resistant ink is insulating ink.
[0027] Preferably, the pre-bent sheet 310 is rectangular in shape.
[0028] In one embodiment, a first reinforcing sheet is provided on a side of the FPC10 body away from the first connection area 100, and a second reinforcing sheet is provided on a side of the FPC10 body away from the second connection area 200. The reinforcing sheet is made of PI, so that the connection between FPC10 and other accessories is more stable, and it is avoided that when FPC10 is bent, the first connection area 100 and the second connection area 200 are pulled, causing FPC10 to be disconnected from other accessories.
[0029] In one embodiment, a display module includes the above-mentioned FPC10 pre-bent structure, so that the assembly of the display module is more convenient.
[0030] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent.
