[0034] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0036] Example 1

[0037] Please refer to Figure 1-5 , provides a display module that is convenient for FPC alignment installation, which includes an iron frame 1 and an FPC2, an opening 101 is provided on the iron frame 1, one end of the FPC2 passes through the opening 101 and is electrically connected to the backlight module inside the iron frame 1, and a magnetic reinforcement steel sheet 3 is provided on one side of the FPC2, the FPC2 passes through the opening 101 of the iron frame 1 and is bent on the back side of the iron frame 1, the magnetic reinforcement steel sheet 3 is magnetically fixed to the iron frame 1, and the magnetic reinforcement steel sheet 3 can also be grounded and conductive, which is convenient for conducting static electricity, and the magnetic reinforcement steel sheet 3 is used to quickly fix the folded FPC2, and after the FPC2 is fixed, a protective layer 4 is covered on the surface of the FPC2, the protective layer 4 can be a protective paper, and can also be a shielding film, and the protective layer 4 is used to protect the components on the FPC2.

[0038] A panel 5 is bonded to the front of the iron frame 1 by OCA optical adhesive, and the panel 5 covers the iron frame 1. Of course, a light shielding layer is also attached to the upper surface of the backlight module. This part is conventional technology and will not be described here.

[0039] Example 2

[0040] The display module provided in Example 1 for facilitating the alignment and installation of the FPC is further optimized. Figure 5As shown, specifically, FPC2 is "L"-shaped, and FPC2 forms a first part 201 and a second part 202 of a right-angle structure. FPC2 is provided with a connecting portion 203 and a plug portion 204. The connecting portion 203 is arranged at the first part 201 of FPC2, and the connecting portion 203 is electrically connected to the backlight module. The magnetic reinforcing steel sheet 3 is arranged at the first part 201 of FPC2. After the connecting portion 203 of FPC2 is connected to the backlight module, it extends from the opening 101 of the iron frame 1 and folds toward the back side of the iron frame 1. Then, the magnetic reinforcing steel sheet 3 at the first part 201 is magnetically fixed to the iron frame 1, so that the FPC2 can be quickly folded and fixed.

[0041] like Figure 2 , 4 As shown, in order to ensure the accurate position of FPC2 after folding, a first alignment line 6 is provided on the back side of the iron frame 1. The first alignment line 6 includes a first cross mark, a first vertical line and a second vertical line. The first cross mark is used to locate an angle of FPC2, and the first vertical line and the second vertical line are used to locate the outer side of FPC2. After FPC2 is folded toward the back side of the iron frame 1, a corner of the first part 201 in FPC2 is aligned with the first cross mark, and the left and right sides of the second part 202 in FPC2 are aligned with the first vertical line and the second vertical line respectively, and the length of the second vertical line is greater than that of the first vertical line. After FPC2 is fixed by magnetic attraction, the accuracy of the installation position of FPC2 can also be checked through the first alignment line 6, so as to facilitate timely adjustment of the position of FPC2.

[0042] A second alignment line 7 is provided on the back side of the iron frame 1, and the second alignment line 7 is used for bonding and aligning the protective layer 4. The protective layer 4 is a strip structure, and therefore, the second alignment line 7 is composed of two second cross marks, and the two second cross marks are respectively located at two corners of the protective layer 4, thereby achieving alignment limitation of the four directions of the plane of the protective layer 4, and facilitating and quickly laminating the protective layer 4.

[0043] Since the first cross mark and the second cross mark are set on the iron frame 1, in order to avoid the staff from making mistakes in identification during assembly, the first alignment line 6 and the second alignment line 7 are set to different colors, such as the first alignment line 6 is red and the second alignment line 7 is blue, so as to facilitate the workers to quickly identify the alignment.

[0044] Through the above-mentioned structural design, by setting the first alignment line 6 and the second alignment line 7 on the back of the iron frame 1, the folded FPC2 and the protective layer 4 are aligned, thereby avoiding the folding deviation of the FPC2 and the attachment deviation of the protective layer 4, improving the accuracy and efficiency of assembly, and facilitating the detection of the FPC2 and the protective layer 4 after installation.

[0045] Example 3

[0046] The display module provided in Example 2 for facilitating the alignment and installation of the FPC is further optimized. Figure 1 , 3 As shown in , 6, specifically, a rubber frame 8 is also provided on the inner side of the iron frame 1, a wedge block 801 is provided on the side of the rubber frame 8, and a card slot 102 is provided on the iron frame 1. The wedge block 801 is inserted into the card block to fix the rubber frame 8 to the iron frame 1. The number of wedge blocks 801 can be freely set according to the length of the side of the rubber frame 8, and the rubber frame 8 can be fixed. A rectangular frame 802 is provided at the position of the rubber frame 8 at the opening 101 of the iron frame 1. The rectangular frame 802 is integrally provided with the rubber frame 8. The rectangular frame 802 is inserted into the opening 101 of the iron frame 1, and the FPC2 passes through the rectangular frame 802. The rectangular frame 802 is used to protect the connecting portion 203 of the FPC2, which can prevent the sharp edge at the opening 101 of the iron frame 1 from scratching the FPC2. At the same time, the rectangular frame 802 can also clamp and wrap the FPC2, thereby improving the installation stability of the FPC2.

[0047] The working principle of the display module provided by the utility model which is convenient for FPC alignment installation is as follows: by replacing the original reinforcing sheet on FPC2 with a magnetic reinforcing steel sheet 3, the magnetic force of the magnetic reinforcing steel sheet is used to attract and fix with the iron frame 1, thereby reducing the use of double-sided adhesive tape, reducing material costs, and reducing the double-sided adhesive tape pasting process, thereby improving assembly efficiency. When repairing defective products, it is easy to disassemble FPC2, and no residual glue will be left on the surface of the iron frame 1, and no damage will be caused to the components on FPC2, thereby protecting FPC2 and ensuring the product quality during repair. Moreover, the magnetic reinforcing steel sheet 3 can be used repeatedly, and no need to be repaired after repair. By replacing it again, the production cost is further reduced. The first alignment line 6 and the second alignment line 7 are set on the back of the iron frame 1 to align the folded FPC2 and the protective layer 4, thereby avoiding the folding deviation of the FPC2 and the attachment deviation of the protective layer 4, improving the accuracy and efficiency of assembly, and facilitating the inspection of the FPC2 and the protective layer 4 after installation. By setting a rectangular frame 802 on the rubber frame 8 and extending the rectangular frame 802 into the opening 101 of the iron frame 1, it can avoid the sharp edge of the opening 101 of the iron frame 1 from scratching the FPC2. At the same time, the rectangular frame 802 can also clamp and wrap the FPC2, thereby improving the installation stability of the FPC2.
