[0046] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0047] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this disclosure should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms "first," "second," and similar terms used in the embodiments of this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0048] refer to Figure 1 , Figure 1This is a schematic diagram of a prior art display module structure. In related technologies, a polarizer 500 and an optical adhesive layer 200 are sequentially disposed between the display panel 100 and the cover plate 400. The display panel 10 includes a main body region 11 and a bending region 12 located on one side of the main body region 11. The cover plate 400 includes a flat portion and a bent portion 410 surrounding at least part of the flat portion. The orthographic projection of the optical adhesive layer 200 onto the display panel 10 is located in the main body region 11 and part of the bending region 12 of the display panel 10. The orthographic projection of the optical adhesive layer 200 onto the cover plate 400 is located in the flat portion and part of the bending region 410 of the cover plate 400. 10. That is, the optical adhesive layer 200 does not completely cover the bent portion 410 of the cover plate 40, resulting in a gap A between the bent area 12 of the display panel 10 and the bent portion of the cover plate 40. If the curvature of the bent portion of the cover plate 40 is too large near the optical adhesive cut-off position (edge), due to the rigidity of the display panel 100 itself, it is very easy to form a rebound wrinkle at this position when the display panel 100 and the cover plate 400 are bonded. This wrinkle will become more severe as the curvature of the short side of the cover plate 400 increases, which may affect the reliability verification of the bonded module screen (under harsh conditions such as high temperature and high humidity).

[0049] For the reasons stated above, this application provides a display module, a display module, and a method for manufacturing the display module. The display module includes a display panel 10, a first adhesive layer 20, a second adhesive layer 30, and a cover plate 40. The display panel 10 includes a main body area 11 and a bending area 12 located on one side of the main body area 11. The first adhesive layer 20 is located on the light-emitting side B1 of the display panel 10; the second adhesive layer 30 is located on the light-emitting side B1 of the display panel 10 and is located at the end of the first adhesive layer 20 near the bending area 12; the cover plate 40 is located on the first adhesive layer 20. The second adhesive layer 30 is located on the side opposite to the display panel 10. The cover plate 40 includes a flat portion and a curved portion 41 surrounding at least part of the flat portion. The orthographic projection of the second adhesive layer 30 on the curved portion 41 coincides with the orthographic projection of the bending area 12 of the display panel 10 on the curved portion 41. In this embodiment, by providing the second adhesive layer 30 to fill the gap between the bending area 12 of the display panel 10 and the bending portion of the cover plate 40, the bending area 12 of the display panel 10 will not exhibit rebound wrinkles when the display panel 10 and the cover plate 40 are attached.

[0050] Next, combine Figures 2-3 The display module provided in this application will be described in detail below. Figure 2 This is a schematic diagram of the display module structure provided in an embodiment of this application; Figure 3 This is a schematic diagram of the display module structure provided in an embodiment of this application;

[0051] The display panel 10 in this embodiment specifically includes a flexible display panel 10. Further, the flexible display panel 10 includes a four-curved flexible display panel. The display panel 10 includes a main body area 11, a bending area 12 located on one side of the main body area 11, and a bonding area 13 located on the side of the bending area 12 away from the main body area 11. The main body area 11 includes a flat portion 111 and an arc-shaped portion 112. The arc-shaped portion 112 is located on the side of the flat portion 111 close to the bending area 12. In the thickness direction of the display panel 10, the display panel 10 has a light-emitting side B1 and a backlight side B2. The bending area 12 of the display panel 10 bends so that the bonding area 13 is located on the backlight side B2 of the main body area 11. In this embodiment, since the display module in this embodiment is an intermediate product of the display module, the bonding area 13 has not yet been bent to the backlight side B2 of the main body area 11 through the bending area 12, that is, the bending area 12 is in an unbent state.

[0052] For example, the flexible display panel 10 is an OLED (organic light-emitting diode) display panel 10, a QLED (quantum dot light-emitting diode) display panel 10, a Micro-LED (micro-light-emitting diode) display panel 10, or a Mini-LED (mini light-emitting diode) display panel 10, etc.

[0053] The display module also includes a polarizer 50 located on the light-emitting side B1 of the display panel 10. The polarizer 50 is projected onto the main body area 11 of the display panel 10. By setting the polarizer 50 on the light-emitting side B1 of the display panel 10, it is beneficial to reduce the influence of ambient light on the display panel 10. The polarizer 50 is set between the cover plate 40 and the display panel 10 to filter ambient light.

[0054] For example, the polarizer 50 can be a linear polarizer 50 or a circular polarizer 50.

[0055] The display module also includes a first adhesive layer 20 located on the light-emitting side B1 of the display panel 10, used to bond the display panel 10 to the cover plate 40. Specifically, the first adhesive layer 20 is located on the side of the polarizer 50 away from the display panel 10, and the first adhesive layer 20 is used to bond the polarizer 50 and the cover plate 40. Further, the orthographic projection of the polarizer 50 on the display panel 10 is within the orthographic projection range of the first adhesive layer 20 on the display panel 10. The orthographic projection of the first adhesive layer 20 on the display panel 10 is located in the main body area 11 and part of the bending area 12 of the display panel 10, that is, the first adhesive layer covers the main body area 11 and part of the bending area 12 of the display panel 10. At the same time, the orthographic projection of the first adhesive layer 20 on the cover plate 40 is located in the flat part and part of the bending part of the cover plate 40 panel, that is, the first adhesive layer 20 does not completely cover the bending part of the display panel 10.

[0056] For example, the material of the first adhesive layer 20 includes optical adhesive.

[0057] The display module also includes a cover plate 40, which specifically includes a curved cover plate 40. Further, the cover plate includes a four-curved cover plate adapted to the four-curved flexible display panel, that is, the edge of the cover plate 40 is curved. The arcuate portion 112 of the display panel 10 is at least partially attached to the edge of the cover plate 40. The cover plate 40 is located on the side of the first adhesive layer away from the display panel 10. In this embodiment, the cover plate 40 includes a flat portion and a curved portion 41 surrounding at least the flat portion. The main body portion of the display panel 10 is attached to the flat portion and part of the curved portion 41 of the cover plate 40. That is, the flat portion 111 of the display panel 10 is attached to the flat portion of the cover plate 40, the arcuate portion 112 of the display panel 10 is attached to the curved portion 41 of the cover plate 40, and the curved portion 41 wraps around the arcuate portion 112 of the display panel 10.

[0058] For example, the material of the cover plate 40 can be a glass cover plate 40, or a flexible organic cover plate 40 formed of polyethylene terephthalate or polyimide. The embodiments of the present invention do not make special limitations on this. When the curved cover plate 40 adopts a flexible organic cover plate 40, it can protect the flexible display module while maintaining a certain degree of flexibility and being easy to bend.

[0059] The display module also includes a second adhesive layer 30, located on the light-emitting side B1 of the display panel 10 and at the end of the first adhesive layer 20 near the bending area 12. The orthographic projection of the second adhesive layer 30 on the bent portion 41 coincides with the orthographic projection of the bent portion 12 of the display panel 10 on the bent portion 41. When the display panel 10, polarizer 50, and first adhesive layer 20 are attached to the cover plate 40, a gap will be formed between the bent area 12 of the display panel 10 and the bent portion 41 of the cover plate 40. If the curvature of the bent portion 41 of the cover plate 40 is too large near the cut-off position of the first adhesive layer, under the action of the rigidity of the display panel 10, this position... Because the gap is prone to rebound wrinkles during the bonding process, this embodiment uses a second adhesive layer 30 to fill the gap, so that the bending area 12 of the display panel 10 can be fixed to the cover plate 40 without rebound wrinkles. Part of the second adhesive layer 30 extends to the side of the first adhesive layer 20 near the display panel 10. Furthermore, part of the second adhesive layer 30 extends to the side of the first adhesive layer 20 near the display panel 10 and adheres to the sidewall of the polarizer 50. In this way, the second adhesive layer 30 completely fills the gap, effectively fixing the display panel 10 to the cover plate 40 without rebound wrinkles. For example, the thickness of the second adhesive layer 30 is between 20-300 μm.

[0060] Furthermore, since the bending area 12 of the display panel 10 needs to be bent in subsequent manufacturing, and the second adhesive layer 30 will affect the bending of the bending area 12, the second adhesive layer 30 needs to be removed after the display panel 10 and the cover plate 40 are bonded together. Therefore, the second adhesive layer 30 in this embodiment includes a variable adhesive layer, which can also be called a non-adhesive adhesive layer. The variable adhesive refers to an adhesive whose viscosity can change significantly with the change of a certain parameter of the external environment. The second adhesive layer 30 has both an adhesive state and a de-adhesive state. The second adhesive layer 30 can be removed by subsequently changing its adhesiveness. For example, the material of the second adhesive layer 30 includes any one of UV-reducing adhesive, low-temperature re-adhesive, and high-temperature re-adhesive. Specifically, when the material of the second adhesive layer 30 is a UV-reducing adhesive, the adhesion between the display panel 10 and the cover plate 40 is reduced by irradiating the second adhesive layer 30 with ultraviolet light; when the material of the second adhesive layer 30 is a low-temperature re-adhesive, the adhesion between the display panel 10 and the cover plate 40 is reduced by lowering the temperature of the second adhesive layer 30; when the material of the second adhesive layer 30 is a high-temperature re-adhesive (such as pressure-sensitive adhesive), the adhesion between the display panel 10 and the cover plate 40 is reduced by raising the temperature of the second adhesive layer 30. Alternatively, the adhesiveness of the second adhesive layer 30 can be reduced by adding a de-adhesive agent.

[0061] In one embodiment, the display module further includes a third adhesive layer 60, which is located between the second adhesive layer and the display panel and is located in the bending area 12 of the display panel 10. The third adhesive layer 60 is used to protect the bending area 12 of the display panel 10.

[0062] For example, the material of the third adhesive layer 60 includes optical adhesive.

[0063] In one embodiment, the display module further includes a support film layer 70 located on the side of the display panel 10 opposite to the polarizer 50 (i.e., on the backlight side B2 of the display panel 10). This support film layer 70 can buffer the stress acting on the display panel 10 and dissipate the heat generated during operation, thus providing some protection for the display panel 10. Exemplarily, the support film layer 70 can be a composite film composed of a mesh adhesive, foam, and copper foil, such as a Super Clean Foam (SCF) composite film.

[0064] For example, the display module also includes a flexible circuit board, one end of which is bonded to the bonding area 13. When the bending area 12 is in a bent state, the flexible circuit board is located on the backlight side B2 of the flexible display panel 102 and is connected to the side of the support film layer 70 away from the flexible display panel 10.

[0065] The display module also includes a support film located on the backlight side B2 of the display panel 10.

[0066] refer to Figures 2-4 The second aspect of this application also provides a method for manufacturing a display module, the method comprising the following steps:

[0067] S10: Provide a display panel 10, which includes a main body area 11 and a bending area 12 located on one side of the main body area 11. The display panel 10 also includes a binding area 13 located on the side of the bending area 12 away from the main body area 11. At this time, the display panel 10 is still in an unbent state.

[0068] S20: A first adhesive material is formed on the light-emitting side B1 of the display panel 10. The orthographic projection of the first adhesive material on the display panel 10 is located in the main body area 11 and part of the bending area 12 of the display panel 10.

[0069] S30: A second adhesive material is formed on the light-emitting side B1 of the display panel 10 and at the end of the first adhesive material near the bending area.

[0070] S40: A cover plate 40 is provided, and the display panel 10 is attached to the cover plate 40 by a first adhesive layer 20 and a second adhesive layer 30; wherein the cover plate 40 includes a flat portion and a curved portion 41 surrounding at least part of the flat portion, and the orthographic projection of the second adhesive layer 30 on the curved portion 41 coincides with the orthographic projection of the bending area 12 of the display panel 10 on the curved portion 41;

[0071] S50: Remove the second adhesive layer 30.

[0072] In this embodiment, before the display panel and the cover plate are bonded together, a second adhesive layer is provided to connect with the bent area of ​​the display panel in its unbent state. When the display panel and the cover plate are bonded together, the display panel is effectively fixed to the cover plate, and no rebound wrinkles will occur. At the same time, after the display panel and the cover plate are bonded together, the second adhesive layer 30 is removed to prevent the second adhesive layer 30 from affecting the pad bending process of the display module.

[0073] In one embodiment, the step of forming the first adhesive layer 20 on the light-emitting side B1 of the display panel 10 further includes:

[0074] S200: A polarizer 50 is formed on the light-emitting side B1 of the display panel 10;

[0075] Furthermore, a first adhesive material is formed on the side of the polarizer 50 away from the display panel 10, and the orthographic projection of the polarizer 50 on the display panel 10 is located within the orthographic projection range of the first adhesive layer 20 on the display panel 10.

[0076] In one embodiment, step S40 specifically includes:

[0077] A cover plate 40 is provided, which is located on the side of the first adhesive material and the second adhesive material opposite to the display panel 10;

[0078] The first adhesive material and the second adhesive material are cured to form a first adhesive layer 20 and a second adhesive layer 30, so that the display panel 10 is attached to the cover plate 40.

[0079] In one embodiment, step S50 specifically includes:

[0080] S51: The second adhesive layer 30 is subjected to a de-adhesion treatment to make the second adhesive layer 30 form a de-adhesion state;

[0081] S52: Peel the second adhesive layer 30 off the display panel 10;

[0082] Furthermore, the anti-adhesion treatment in this step includes subjecting the second adhesive layer 30 to UV light, low temperature, high temperature, or adding an anti-adhesion agent. For example, when the material of the second adhesive layer 30 is a UV anti-adhesion adhesive, the adhesion between the display panel 10 and the cover plate 40 is reduced by irradiating the second adhesive layer 30 with ultraviolet light; when the material of the second adhesive layer 30 is a low temperature anti-adhesion adhesive, the adhesion between the display panel 10 and the cover plate 40 is reduced by lowering the temperature of the second adhesive layer 30; when the material of the second adhesive layer 30 is a high temperature anti-adhesion adhesive, the adhesion between the display panel 10 and the cover plate 40 is reduced by raising the temperature of the second adhesive layer 30. Of course, the adhesion of the second adhesive layer 30 can also be reduced by adding an anti-adhesion agent.

[0083] Furthermore, after removing the second adhesive layer 30, the bending area 12 is bent so that the bonding area 13 of the display panel 10 is located on the backlight side B2 of the display panel 102.

[0084] A third aspect of this application also provides a display module, which includes the display module manufactured by the manufacturing method in any of the above embodiments.

Furthermore, the processes depicted in the drawings do not necessarily require a specific or sequential order to achieve the desired result.
