Description

Technical Field

[0001] This utility model relates to the field of LED technology, and in particular to a display module and electronic device. Background Technology

[0002] Display modules are widely used, and the yield rate of LCD modules directly affects production efficiency and user experience. The edge-sealing adhesive needs to be bent, but the current edge-sealing adhesive structure is prone to stress concentration in the bending area when bent, which can cause warping and result in product defects. Utility Model Content

[0003] In view of the above situation, it is necessary to provide a display module and electronic device to address the problem that the edge-wrapping adhesive of the display module in the prior art is prone to peeling.

[0004] A display module includes a composite layer and a release layer stacked from top to bottom. The composite layer is deformable and has a first space and a second space extending through opposite ends of the composite layer. The first space and the second space are used to release the bending stress of the composite layer. Each opposite end of the composite layer has a bent portion and a straight portion, and a bending line is provided between the two bent portions and the two straight portions. The two bending lines are respectively adjacent to the first space and the second space. The composite layer includes a graphite layer, a copper foil layer and an insulating layer arranged sequentially from top to bottom. The release layer is detachably connected to the insulating layer.

[0005] The beneficial effects of this utility model are:

[0006] When applying adhesive to the LCD module using the composite layer and release layer, firstly, peel off the top portion of the release layer and attach the exposed insulating layer to the front edge of the LCD module; secondly, peel off the middle portion of the release layer and attach the exposed insulating layer to the FPC of the LCD module; finally, peel off the bottom portion of the release layer and attach the exposed graphite layer to the back panel of the LCD module. Since the front and back panels of the LCD module are on two opposite surfaces, the composite layer needs to be bent to form a corner (i.e., a bending area) during edge application. The top portion of the composite layer is divided into three parts along the X-axis using the first and second spaces, thereby releasing the stress at the corner and preventing warping. The two bending lines are adjacent to the first and second spaces respectively, making the bending process smoother and more convenient, further releasing stress in the bending area.

[0007] Furthermore, the insulating layer includes a first portion and a second portion of the insulating layer that are spaced apart. The first portion of the insulating layer has a first space and a portion of the second space at opposite ends. The second portion of the insulating layer has a portion of the second space. The first portion of the insulating layer has one of the bending lines, and the second portion of the insulating layer has the other bending line.

[0008] Furthermore, both the first space and the second space are U-shaped grooves.

[0009] Furthermore, the release layer includes a first release layer portion, a second release layer portion, and a third release layer portion. The two opposite ends of the second release layer portion are connected to the first release layer portion and the third release layer portion through pre-broken wires. The first release layer portion abuts against the first insulating layer portion, and the second release layer portion abuts against a portion of the first insulating layer portion and the second insulating layer portion.

[0010] Furthermore, the width of the first portion of the release layer is smaller than the width of the second portion of the release layer and the width of the third portion of the release layer.

[0011] Furthermore, the bent line includes a solid line and a dashed line, and the length ratio of the solid line to the dashed line is 2:1.

[0012] Furthermore, the thickness of the copper foil layer is 0.028 mm to 0.032 mm.

[0013] In addition, this utility model also provides an electronic device, which includes the display module as described above. Attached Figure Description

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0020] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Furthermore, the various embodiments of the invention, the features within those embodiments, and the features of the embodiments may be freely combined without obvious conflict or contradiction.

[0022] A display module, such as Figure 1 As shown, it includes a composite layer 1 and a release layer 2 stacked from top to bottom. The composite layer 1 is deformable and includes a graphite layer 11, a copper foil layer 12 and an insulating layer 13 arranged sequentially from top to bottom.

[0023] Specifically, such as Figures 1 to 4As shown, a first space 100 and a second space 101 are provided at opposite ends of the composite layer 1. The first space 100 and the second space 101 are used to release the bending stress of the composite layer 1. Both the first space 100 and the second space 101 are U-shaped grooves. Each opposite end of the composite layer 1 is provided with a bent portion 102 and a straight portion 103. A bending line 104 is provided between the two bent portions 102 and the two straight portions 103. The two bending lines 104 are adjacent to the first space 100 and the second space 101, respectively. The insulating layer 13 includes a first insulating layer portion 131 and a second insulating layer portion 132 that are spaced apart. The first insulating layer portion 131 is provided with a first space 100 and a portion of the second space 101 at opposite ends. The second insulating layer portion 132 is provided with a portion of the second space 101. The liquid crystal module is edge-wrapped using a deformable graphite layer 11, a copper foil layer 12, and an insulating layer 13. To ensure the yield of the liquid crystal module, the front and back panels of the liquid crystal module, as well as the FPC, need to be edge-wrapped. Since the front and back panels of the liquid crystal module are on two opposing planes, the composite layer 1 needs to be bent to form a corner (i.e., a bending area) during edge-wrapping. The uppermost part of the composite layer 1 is divided into three parts along the X-axis using the first space 100 and the second space 101, thereby releasing the stress of the composite layer 1 forming the corner and preventing warping. By using two bending lines 104 adjacent to the first space 100 and the second space 101 respectively, the bending process of the bending part 102 is smoother and more convenient, further releasing the stress in the bending area.

[0024] Specifically, each of the graphite layer 11, copper foil layer 12, and the first portion 131 of the insulating layer has a bending line 104, and each of the graphite layer 11, copper foil layer 12, and the second portion 132 of the insulating layer has another bending line 104. One bending line 104 is adjacent to the first space 100, and the other bending line 104 is adjacent to the second space 101. Each bending line includes both solid and dashed lines, with the ratio of the length of the solid line to the length of the dashed line being 2:1. By having one bending line 104 adjacent to the first space 100 and the other bending line 104 adjacent to the second space 101, the bending process is smoother and more convenient, further releasing stress in the bending area during bending. The ratio of the length of the solid line to the length of the dashed line ensures that bending can be achieved without breakage.

[0025] Specifically, release layer 2 is detached from insulating layer 13. Release layer 2 includes a first release layer portion 21, a second release layer portion 22, and a third release layer portion 23. The two opposite ends of the second release layer portion 22 are connected to the first release layer portion 21 and the third release layer portion 23 via pre-cut wires 24. The first release layer portion 21 abuts against the first insulating layer portion 131, and the second release layer portion 22 abuts against portions of the first insulating layer portion 131 and the second insulating layer portion 132. The width of the first release layer portion 21 is smaller than the width of the second release layer portion 22 and the width of the third release layer portion 23. When applying edge-sealing adhesive to the LCD module using the combined layer 1 and release layer 2, firstly peel off the topmost first release layer portion 21, as shown below. Figure 2 In the Z-axis direction, the exposed area of ​​the first part 131 of the insulating layer is attached to the front edge of the LCD module; next, the second part 22 of the release layer located in the middle is peeled off, and the exposed areas of the first part 131 and the second part 132 of the insulating layer are attached to the FPC of the LCD module; finally, the third part 23 of the release layer located at the bottom is peeled off, and the exposed area of ​​the graphite layer 11 is attached to the back plate of the LCD module. The separation of the first part 21, the second part 22 and the third part 23 of the release layer is achieved by pre-cutting line 24. The size of the first part 21, the second part 22 and the third part 23 of the release layer is adapted to the size of the front, FPC and back plate of the LCD module.

[0026] Specifically, the thickness of copper foil layer 12 is 0.03 mm.

[0027] In this invention, when applying edge-sealing adhesive to a liquid crystal module using the composite layer 1 and release layer 2, the uppermost portion of release layer 2 is first peeled off, and the exposed area of ​​insulating layer 13 is attached to the front edge of the liquid crystal module; next, the middle portion of release layer 2 is peeled off, and the exposed area of ​​insulating layer 13 is attached to the FPC of the liquid crystal module; finally, the lowermost portion of release layer 2 is peeled off, and the exposed area of ​​graphite layer 11 is attached to the back panel of the liquid crystal module. Since the front and back panels of the liquid crystal module are on two opposite vertical surfaces, the composite layer 1 needs to be bent to form a corner (i.e., a bending area) during edge sealing. The uppermost portion of the composite layer 1 is divided into three parts along the X-axis direction using the first space 100 and the second space 101, thereby releasing the stress of bending the composite layer 1 to form the corner and preventing warping. By using two bending lines 104 adjacent to the first space 100 and the second space 101 respectively, the bending process of the bending part 102 is smoother and more convenient, further releasing the stress in the bending area.
