Abstract
Description
Technical Field
[0001] This utility model relates to the field of display module technology, and in particular to a display module structure. Background Technology
[0002] After the display module is assembled, the connector on the FPC needs to pass through the phone's casing frame. Currently, the method involves adding a PET strip to the reinforcing plate on the back of the connector. The PET strip guides the connector through the phone's frame and engages with the connector on the motherboard, and then the PET strip is removed. Alternatively, a double-sided adhesive strip can be designed on the PET strip to securely attach it to the reinforcing plate.
[0003] However, some end customers also request that QR codes be laser-engraved or printed on the reinforcing plate on the back of the FPC connector. These QR codes are linked to the production batch, date, and production process of each material and processing step of the product, making it easy to trace.
[0004] Existing technology as per the instruction manual Figure 1 , Figure 2 and Figure 3 As shown, the PET on the reinforcing plate blocks the QR code, requiring the PET to be torn off before scanning, which is inconvenient and affects production efficiency.
[0005] To this end, this application proposes a display module structure to improve the convenience of barcode scanning and recognition and increase production efficiency. Utility Model Content
[0006] Based on this, it is necessary to provide a display module structure to address the aforementioned technical issues. A reinforcing plate and strong / weak adhesive are arranged side by side at the overlap of the main FPC board and PET to prevent the strong / weak adhesive from obstructing the reinforcing plate. At the same time, a through hole is made on the PET at the position corresponding to the information QR code, so that the information QR code can be exposed. When inspecting the information QR code, it can be scanned directly through the through hole, thereby improving the convenience of scanning and increasing production efficiency.
[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0008] A display module structure used in the assembly of mobile phone display modules.
[0009] The display module structure specifically includes: a display screen and a PET, with a main FPC board and a backlight FPC respectively led out from the display screen, and the main FPC board and the backlight FPC are interconnected;
[0010] The main FPC board is stacked on one end away from the display screen and the other end of the PET. A connector is provided on the main FPC board. A reinforcing plate and strong and weak adhesive are arranged side by side at the overlapping part of the main FPC board and the PET. The reinforcing plate supports the connector. An information QR code is provided on the side of the reinforcing plate facing the PET.
[0011] The PET has a through hole at the location of the information QR code.
[0012] In a preferred embodiment of the display module structure provided by this utility model, the projected area of the through hole is larger than the projected area of the information QR code.
[0013] In a preferred embodiment of the display module structure provided by this utility model, a gap is left between the edge of the strong and weak adhesive and the edge of the through hole.
[0014] In a preferred embodiment of the display module structure provided by this utility model, the strong and weak adhesive is a double-sided adhesive, with one side of the strong and weak adhesive being set to strong adhesion and the other side being set to weak adhesion.
[0015] In a preferred embodiment of the display module structure provided by this utility model, the strong adhesive side of the strong adhesive is bonded to the PET, and the weak adhesive side of the strong adhesive is bonded to the main FPC board.
[0016] In a preferred embodiment of the display module structure provided by this utility model, a rough adhesion area is provided at the connection between the PET and the strong and weak adhesive.
[0017] In a preferred embodiment of the display module structure provided by this utility model, the thickness of the reinforcing plate and the strong and weak adhesive are equal.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] The display module structure provided by this utility model has a reinforcing plate and strong and weak adhesives arranged side by side at the overlapping part of the main FPC board and PET, so as to avoid the strong and weak adhesives from obstructing the reinforcing plate. At the same time, a through hole is opened on the PET at the position corresponding to the information QR code, so that the information QR code can be exposed. When inspecting the information QR code, it can be scanned directly through the through hole, thereby improving the convenience of scanning and improving production efficiency.
[0020] Setting the projected area of the through hole to be larger than the projected area of the information QR code can avoid deviations during laser engraving or inkjet printing of the information QR code, as well as deviations in incoming material cutting and attachment, which would prevent the information QR code from being completely displayed in the through hole. This achieves the goal of avoiding the information QR code being blocked and affecting the scanning effect.
[0021] One side of the strong and weak adhesive is set to strong adhesion, and the other side is set to weak adhesion. At the same time, the strong adhesion side of the strong and weak adhesive is bonded to the PET, and the weak adhesion side of the strong and weak adhesive is bonded to the main FPC board. After the display module is assembled, no adhesive residue will be left on the main FPC board after the PET is peeled off. Attached Figure Description

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] As described in the background section, the PET on the reinforcing plate blocks the QR code, requiring the PET to be torn off before scanning and recognition, which is inconvenient and affects production efficiency.
[0036] To solve this technical problem, this utility model provides a display module structure that is applied to the assembly of mobile phone display modules.
[0037] For details, please refer to Figures 4-9 The display module structure specifically includes: a display screen 1 and a PET4. A main FPC board 2 and a backlight FPC 3 are respectively led out from the display screen 1, and the main FPC board 2 and the backlight FPC 3 are interconnected.
[0038] The end of the main FPC board 2 furthest from the display screen 1 overlaps with one end of the PET4. A connector 7 is provided on the main FPC board 2. A reinforcing plate 5 and strong / weak adhesive 6 are arranged side by side at the overlap of the main FPC board 2 and PET4. The reinforcing plate 5 supports the connector 7. An information QR code 8 is provided on the side of the reinforcing plate 5 facing the PET4. A through hole 401 is provided on the PET4 corresponding to the position of the information QR code 8.
[0039] The display module structure provided by this utility model has a reinforcing plate 5 and a strong and weak adhesive 6 arranged side by side at the overlapping part of the main FPC board 2 and PET4 to avoid the strong and weak adhesive 6 from obstructing the reinforcing plate 5. At the same time, a through hole 401 is opened on the PET4 at the position corresponding to the information QR code 8, so that the information QR code 8 is exposed. When inspecting the information QR code 8, it can be scanned directly through the through hole 401, thereby improving the convenience of scanning and improving production efficiency.
[0040] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0041] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0042] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0043] Example 1
[0044] Please refer to Figure 1 , Figures 4-6 A display module structure includes a display screen 1 and a backlight FPC 4. A main FPC board 2 and a backlight FPC 3 are respectively led out from the display screen 1, and the main FPC board 2 and the backlight FPC 3 are interconnected. The display screen 1, the main FPC board 2, and the backlight FPC 3 are all prior art, used to realize the transmission of signals from the display screen 1.
[0045] In this design, the end of the main FPC board 2 furthest from the display screen 1 overlaps with one end of the PET 4, and the PET 4 extends towards the main FPC board 2 to increase the contact area between the main FPC board 2 and the PET 4. A connector 7 is mounted on the main FPC board 2. A reinforcing plate 5 and strong / weak adhesive 6 are arranged side-by-side at the overlap of the main FPC board 2 and the PET 4. The connector 7 connects to the motherboard connector on the mobile phone motherboard to enable signal interaction. The reinforcing plate 5 supports the connector 7 to enhance the strength of the connection point. An information QR code 8 is mounted on the side of the reinforcing plate 5 facing the PET 4. The information QR code 8 is prepared by laser engraving or inkjet printing. The information scanned from the information QR code 8 is linked to the production batch and date of each material and processing step of the product, facilitating traceability.
[0046] To facilitate scanning of the information QR code 8, a through hole 401 is provided at the overlap between the PET4 and the information QR code 8. During production, the scanning device can directly scan the information QR code 8 through the through hole 401. Unlike traditional display module structures, it is no longer necessary to tear off the PET4 before scanning, which would affect production efficiency.
[0047] Considering the incoming material punching deviation, attachment deviation, and deviation during the printing of the information QR code 8, the projected area of the through hole 401 is larger than the projected area of the information QR code 8. This is to prevent the PET4 from obscuring the edge of the information QR code 8 after installation, which would prevent the information QR code 8 from being fully displayed in the through hole 401 and thus cause scanning failure.
[0048] Example 2
[0049] The display module structure provided in Embodiment 1 is further optimized, specifically, as follows: Figure 5 , Figure 7 and Figure 8As shown, a gap is left between the edge of the strong and weak adhesive 6 and the edge of the through hole 401, thereby increasing the contact area between the reinforcing plate 5 and PET4, and facilitating the installation of PET4. If the strong and weak adhesive 6 and the edge of the through hole 401 are too close, there will not be enough room for adjustment when installing PET4, and the edge of the information QR code 8 may be blocked by PET4.
[0050] It is worth noting that the strong-weak adhesive 6 is a double-sided adhesive, with one side being strongly tacky and the other side being weakly tacky. The strongly tacky side of the strong-weak adhesive 6 adheres to PET4, while the weakly tacky side adheres to the main FPC board 2. A rough adhesive area 402 is provided at the connection between PET4 and the strong-weak adhesive 6 to improve the stability of the connection.
[0051] With the above structural design, after the display module structure and the mobile phone motherboard are assembled, PET4 needs to be peeled off. At this time, the strong adhesive side of the strong and weak adhesive 6 adheres to PET4, so that the strong and weak adhesive 6 can be taken away together when PET4 is peeled off. At the same time, the weak adhesive side of the strong and weak adhesive 6 adheres to the main FPC board 2. Because the adhesion is poor, no adhesive residue will remain on the main FPC board 2, ensuring the cleanliness of the main FPC board 2.
[0052] Example 3
[0053] The display module structure provided in the above embodiments is further optimized, such as... Figure 5 As shown, the reinforcing plate 5 and the strong / weak adhesive 6 have the same thickness. When assembling the main FPC board 2 and PET 4, the strong / weak adhesive 6, with a thickness equal to that of the reinforcing plate 5, ensures complete contact between the adhesive 6 and the contact surface of the main FPC board 2. It also ensures that the overlapping area of the main FPC board 2 and PET 4 remains flat.
[0054] The usage process of the display module structure provided by this utility model is as follows:
[0055] The display screen 1, main FPC board 2, and backlight FPC 3 are connected in a conventional manner. Then, PET 4 is stacked on top of the main FPC board 2, with the ends of PET 4 extending towards the main FPC board 2. A reinforcing plate 5 and strong / weak adhesive 6 are placed side-by-side between PET 4 and the main FPC board 2. At this point, the weaker adhesive side of the strong / weak adhesive 6 adheres to the main FPC board 2, while the stronger adhesive side adheres to PET 4. The information QR code 8 on the back of the reinforcing plate 5 is aligned with the through-hole 401 on the PET 4, thus fully exposing the information QR code 8 through the through-hole 401. During assembly, the information QR code 8 can be scanned directly through the through-hole 401 to confirm the information of the reinforcing plate 5. After the display module is assembled, PET 4 is peeled off, causing the weaker adhesive side of the strong / weak adhesive 6 to detach from the main FPC board 2.
