[0033] In order to make the person skilled in the art better understand the utility model scheme, the technical scheme in the utility model embodiment will be described clearly and completely below in conjunction with the drawings in the utility model embodiment. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the utility model.

[0034] As the background art, the traction mela is attached to the steel sheet reinforcement, which covers the laser-engraved two-dimensional code. When the whole machine is assembled, the traction mela is torn off, which will leave glue on the laser-engraved code, affecting the two-dimensional code scanning.

[0035] In order to solve this technical problem, the utility model provides a display module traction mela structure, which is applied to mobile phone whole set packaging.

[0036] Specifically, please refer to Figures 1-7 The display module traction mela structure specifically comprises:

[0037] The mela body 1 comprises a traction part 10 and a connecting part 11. The connecting part 11 is provided with an opening 110 in the middle part, and the outer surface of the connecting part 11 is provided with a glue layer 111.

[0038] The display module 2 comprises a cover plate 20, a backlight module 21 and a display screen module 22 which are nested from outside to inside. The bottom of the display screen module 22 is connected with a main screen FPC 23. The steel sheet reinforcement at the connector bending part is adhered to the mela body 1 through the glue layer 111.

[0039] The display module traction mela structure provided by the utility model sets the opening 110 on the connecting part 11 of the mela body 1. The position of the opening 110 corresponds to the position of the laser-engraved two-dimensional code in the display module 2. The glue layer 111 avoids the opening 110 position, preventing the traction mela glue from remaining on the laser-engraved two-dimensional code of the FPC steel sheet reinforcement. At the same time, the traction mela does not affect the code scanning after being attached.

[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 Figures 1-6 A display module traction Mylar structure, comprising

[0045] Myla body 1, Myla body 1 includes a traction part 10 and a connecting part 11, the connecting part 11 has an opening 110 in the middle, and the outer surface of the connecting part 11 is provided with an adhesive layer 111;

[0046] The display module 2 includes a cover plate 20, a backlight module 21, and a display module 22 nested from the outside to the inside. The bottom of the display module 22 is connected to the main screen FPC 23. The steel sheet reinforcement of the main screen FPC 23 at the connector bending part is bonded to the Mylar body 1 through the adhesive layer 111.

[0047] Specifically, the Mylar body 1 is made of non-adhesive PET, preferably black, anti-static XUN-PET102PET with a thickness of 0.1mm. The black material is used for easy observation and to avoid missed application. The Mylar body 1 is 45-55mm long, and the connecting part 11 is convex, with the protruding part recessed inward by 1.2-1.5mm relative to the main body. The bent part of the connector of the main screen FPC23 is treated with green oil to improve its flexibility and overlaps with the protruding part of the connecting part 11, making it easier to peel off the Mylar body 1 and improving convenience.

[0048] Specifically, the main screen FPC23 has a laser QR code on the steel reinforcement at the connector bend. The opening 110 is 0.3-0.4mm outward from the laser QR code to avoid obstructing it. It should be noted that, due to the different models of laser QR codes on the market, the size of the opening 110 is set to different dimensions depending on the model of the laser QR code.

[0049] Specifically, adhesive layer 111 is double-sided adhesive, with one side being strong adhesion and the other weak adhesion. Specifically, the Mylar body 1 has a smooth surface and a matte surface. The strong adhesion layer of the double-sided adhesive bonds to the smooth surface of the Mylar body 1, while the weak adhesion layer is reinforced with the steel sheet of the main screen FPC23, facilitating the removal of the double-sided adhesive when pulling the Mylar. The preferred double-sided adhesive model is Zhixing H2651R.

[0050] Specifically, the tail end of the traction unit 10 is connected to a fixing strap 3, the end of which extends through the display module 2 to the outside. The fixing strap 3 is used to secure the traction vehicle.

[0051] The display module traction Mylar structure provided in this embodiment sets an opening 110 on the traction Mylar corresponding to the position of the laser QR code, so that the adhesive layer 111 avoids the position of the opening 110, preventing the traction Mylar adhesive from remaining on the laser-engraved QR code on the FPC steel sheet reinforcement. At the same time, attaching the traction Mylar does not affect the scanning of the code, thus improving product quality.

[0052] Example 2

[0053] The display module traction Mylar structure provided in Embodiment 1 is further optimized, specifically, as follows: Figure 7 As shown, a high-transparency PET12 is provided at the opening 110. The high-transparency PET12 is the same size as the opening 110 and the back of the high-transparency PET12 is not covered with adhesive.

[0054] The above structural design prevents the laser-engraved QR code on the steel sheet from being contaminated by dust, while the high transparency of PET12 does not affect scanning.

[0055] The usage process of the display module traction Mylar structure provided by this utility model is as follows:

[0056] By setting an opening 110 on the traction mylar corresponding to the position of the laser QR code, and making the opening 110 0.3-0.4mm outward relative to the laser QR code, the main screen FPC23 is treated with green oil at the connector bending position to improve its flexibility. The traction mylar is attached to the steel sheet reinforcement with a weak adhesive surface. There is no glue at the opening 110 position. In this way, after the traction mylar is attached, the QR code is exposed and does not affect the QR code scanning. After the traction mylar is removed, there is no glue residue on the laser-engraved QR code, which does not affect the secondary scanning of the laser-engraved code, thus improving product quality.
