[0059] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0060] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs.

"Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0061] Please refer to Figure 1-2 As shown, a related display module 100 includes a display panel 1 and a composite tape 2. The composite tape 2 is attached to one side of the display panel 1 to increase the heat dissipation and impact resistance of the display panel 1.

[0062] With the development of display technology, the edge of the display panel 1 is designed to be a curved surface, which is conducive to increasing the display area and improving the screen-to-body ratio, thereby improving the user experience. Figure 1 and 2 As shown, the display panel 1 includes a flat area 11 and a bending area 12 surrounding the flat area 11 , wherein the display panel 1 is a plane in the flat area 11 , and is bent into a curved surface in the bending area 12 .

[0063] In the corner of the display module 100 (such as the first area 101 in the figure), the composite tape 2 and the display panel 1 have poor adhesion, and are prone to problems such as false adhesion and film peeling after the composite tape 2 is adhered, which affects the display effect. Figure 2 The first position 102 is characterized by wrinkles, bubbles, and other poor appearance.

[0064] Based on this, the present application provides a display panel solution to solve the above problems.

[0065] Please refer to Figure 3-5 As shown, a display module 100 provided in an embodiment of the present application is shown. The display module 100 includes a display panel 1 and a composite tape 2.

[0066] The display panel 1 has a flat area 11 and a bending area 12 surrounding the flat area 11, the bending area 12 includes a first bending area 121, a second bending area 122 and an arc angle area 123, and along the circumference of the flat area 11, the first bending area 121, the arc angle area 123 and the second bending area 122 are adjacent to each other in sequence; the composite tape 2 is arranged on one side of the display panel 1, and the composite tape 2 includes a first adhesive layer 21, a buffer layer 22 and a first metal layer 23 stacked in sequence in a direction away from the display panel 1; wherein the orthographic projection of the first metal layer 23 on the display panel 1 does not overlap with the arc angle area 123.

[0067] After long-term research, the inventors found that in the arc corner area 123, the bonding effect between the composite tape 2 and the display panel 1 is poor. The reason for the false bonding is that the film layer in the arc corner area 123 is pressed into an irregular spherical shape from a planar state. Therefore, the stress in the arc corner area 123 is relatively large. After the composite tape 2 is bonded to the display panel 1, due to the greater strength of the first metal layer 23 in the composite tape 2, the first metal layer 23 in the arc corner area 123 is prone to rebound, resulting in false bonding in the arc corner area 123.

[0068] In the display module 100 provided in this embodiment, the orthographic projection of the first metal layer 23 in the composite tape 2 on the display panel 1 does not overlap with the arc corner area 123, that is, the first metal layer 23 in the arc corner area 123 is removed, thereby avoiding false sticking in the arc corner area 123 due to the greater strength of the first metal layer 23, solving the problem of film layer peeling off after the composite tape 2 in the arc corner area 123 is pasted, avoiding functional defects, and improving the display performance of the display module 100.

[0069] Furthermore, the display panel 1 has two first bending regions 121 symmetrically arranged along the flat region 11, and two second bending regions 122 symmetrically arranged along the flat region 11. Specifically, the two first bending regions 121 are arranged along the row direction (such as the X direction in the figure), and the second bending regions 122 are arranged along the column direction (such as the Y direction in the figure). Correspondingly, there is an arc angle region 123 between any two adjacent first bending regions 121 and second bending regions 122, so the display panel 1 has four arc angle regions 123.

[0070] Among them, the first metal layer 23 has high hardness and strength, and can provide necessary support for the composite tape 2 to keep it in a stable shape and structure. At the same time, the first metal layer 23 can support other layers to prevent the display module 100 from being deformed, collapsed or broken due to external forces during use. It can improve the overall mechanical strength of the display module 100, so that it can withstand greater tension, pressure and shear force. Preferably, the first metal layer 23 is made of copper foil or aluminum foil.

[0071] Please continue to refer to Figure 4 and 5As shown, in one embodiment, the orthographic projection of the first metal layer 23 on the display panel 1 is located in the flat area 11, the first bending area 121, and the second bending area 122. Specifically, only the first metal layer 23 in the arc angle area 123 is removed, and the first metal layer 23 in other areas is retained to maximize the function of the first metal layer 23, and at the same time, the problem of film peeling after the composite tape 2 is attached in the arc angle area 123 is solved.

[0072] During the use of the display module 100, it may be subjected to external impact or vibration, and the buffer layer 22 can absorb the energy of these impacts and vibrations to reduce the impact on the display module 100. For example, when the display device accidentally falls or is hit, the buffer layer 22 can effectively reduce the impact force and protect the display panel 1 from damage.

[0073] At the same time, since there may be unevenness or tiny gaps on the surface of the display panel 1, the buffer layer 22 can fill these gaps to make the composite tape 2 and the display panel 1 fit more tightly. This can avoid problems such as loose adhesion and bubble generation caused by the existence of gaps, and improve the quality and stability of adhesion. During the pasting and use of the composite tape 2, it may be deformed due to factors such as temperature changes and mechanical stress. The buffer layer 22 has a certain elasticity and can adjust this deformation to a certain extent, so that the composite tape 2 maintains a good shape and performance. Preferably, the buffer layer 22 is a material such as foam or polyurethane.

[0074] The first adhesive layer 21 is used to bond the composite tape 2 to the display panel 1, ensuring that the composite tape 2 is tightly combined with the display panel 1 and is not easily separated. When the display panel 1 is subjected to external force or vibrates during use, the first adhesive layer 21 can disperse stress to avoid stress concentration at a certain point and damage to the composite tape 2 or the display panel 1. Preferably, at least part of the first adhesive layer 21 is in a grid shape, wherein the grid structure can be used for exhaust to avoid the generation of lamination bubbles. Specifically, part of the area on the first adhesive layer 21 is in a grid shape, or the entire area is in a grid shape.

[0075] Please continue to refer to Figure 4 As shown, in one embodiment, the orthographic projection of the first adhesive layer 21 on the display panel 1 is located in the flat area 11, the first bending area 121, the second bending area 122 and the arc angle area 123, and the orthographic projection of the buffer layer 22 on the display panel 1 is located in the flat area 11, the first bending area 121, the second bending area 122 and the arc angle area 123. Specifically, while removing the first metal layer 23 in the arc angle area 123, the first adhesive layer 21 and the buffer layer 22 in the arc angle area 123 are retained to retain the functions of the first adhesive layer 21 and the buffer layer 22 in the arc angle area 123, and at the same time, the problem of film peeling after the composite adhesive tape 2 in the arc angle area 123 is solved.

[0076] Preferably, the orthographic projection of the first adhesive layer 21 on the display panel 1 completely overlaps with the orthographic projection of the buffer layer 22 on the display panel 1. Specifically, the first adhesive layer 21 is used to bond the buffer layer 22 to the display panel 1, so the orthographic projection of the first adhesive layer 21 on the display panel 1 completely overlaps with the orthographic projection of the buffer layer 22 on the display panel 1, which can ensure that the composite tape 2 is tightly bonded to the display panel 1 to avoid gaps.

[0077] Reference Figure 6 As shown, in one embodiment, the display module 100 also includes a first conductive liquid layer 3, which is located on the side of the buffer layer 22 away from the display panel 1, and the orthographic projection of the first conductive liquid layer 3 on the display panel 1 is located in the arc angle area 123, and has no overlap with the flat area 11, the first bending area 121, and the second bending area 122.

[0078] Specifically, since the first metal layer 23 in the arc angle area 123 is removed, but the first adhesive layer 21 and the buffer layer 22 are retained, the buffer layer 22 is not covered by the first metal layer 23 in the arc angle area 123 and is in a bare state. In this embodiment, the first conductive liquid layer 3 is used to cover the exposed buffer layer 22, wherein the first conductive liquid layer 3 is used to reduce electromagnetic interference and is beneficial to improving the strength of the display module 100. At the same time, it avoids false sticking in the arc angle area 123 and solves the problem of film peeling after the composite tape 2 in the arc angle area 123 is attached. Furthermore, the first conductive liquid layer 3 can be prepared by spraying.

[0079] Preferably, the thickness of the first conductive liquid layer 3 is the same as the thickness of the first metal layer 23, which is beneficial to ensure the flatness of the film layer before bending and to reduce wrinkles after bending.

[0080] Preferably, the first conductive liquid layer 3 includes conductive glue, which is used to reduce electromagnetic interference and is beneficial to improving the strength of the display module 100. At the same time, the bonding performance of the conductive glue is used to ensure the tightness of the connection between the film layers and avoid film peeling.

[0081] Preferably, the first conductive liquid layer 3 is black, which is beneficial to reducing reflection of ambient light and ensuring the display effect of the display module 100 .

[0082] Reference Figure 7As shown, in one embodiment, the orthographic projection of the first adhesive layer 21 on the display panel 1 is located in the flat area 11, the first bending area 121, and the second bending area 122, and does not overlap with the arc angle area 123; the orthographic projection of the buffer layer 22 on the display panel 1 is located in the flat area 11, the first bending area 121, and the second bending area 122, and does not overlap with the arc angle area 123. Specifically, when the first metal layer 23 in the arc angle area 123 is removed, the first adhesive layer 21 and the buffer layer 22 in the arc angle area 123 are removed at the same time, so as to solve the problem of film peeling after the composite adhesive tape 2 in the arc angle area 123 is attached.

[0083] Preferably, the orthographic projection of the first adhesive layer 21 on the display panel 1 and the orthographic projection of the buffer layer 22 on the display panel 1 completely overlap, so as to ensure that the composite adhesive tape 2 is tightly bonded to the display panel 1 and avoid gaps.

[0084] Reference Figure 8 As shown, in one embodiment, the display module 100 also includes a second conductive liquid layer 4, which is located on the same side of the composite tape 2 relative to the display panel 1, and the orthographic projection of the second conductive liquid layer 4 on the display panel 1 is located in the arc angle area 123, and has no overlap with the flat area 11, the first bending area 121, and the second bending area 122.

[0085] Specifically, since the first metal layer 23, the first adhesive layer 21 and the buffer layer 22 in the arc angle area 123 are all removed, the display panel 1 is not covered by the composite tape 2 in the arc angle area 123 and is in a bare state. In this embodiment, the second conductive liquid layer 4 is used to cover the exposed display panel 1, wherein the second conductive liquid layer 4 is used to reduce electromagnetic interference and is beneficial to improve the strength of the display module 100. At the same time, the problem of film peeling in the arc angle area 123 is solved. Furthermore, the second conductive liquid layer 4 can be prepared by spraying.

[0086] Preferably, the thickness of the second conductive liquid layer 4 is the same as the thickness of the composite tape 2, which is beneficial to ensure the flatness of the film layer before bending and to reduce wrinkles after bending.

[0087] Preferably, the second conductive liquid layer 4 includes conductive glue, which is used to reduce electromagnetic interference and is beneficial to improving the strength of the display module 100. At the same time, the bonding performance of the conductive glue is used to ensure the tightness of the connection between the film layers and avoid film peeling.

[0088] Preferably, the second conductive liquid layer 4 is black, which is beneficial to reducing reflection of ambient light and ensuring the display effect of the display module 100 .

[0089] It should be noted that for the convenience of display, Figure 4 , Figure 6-Figure 8, a schematic diagram showing the display module 100 in a flat state before being bent is shown. After the display module 100 is bent, the film layers in the bending area 12 are all in a curved state.

[0090] Reference Fig. 9 As shown, in one embodiment, the display module 100 further includes a cover plate 5, which is located on a side of the display panel 1 away from the composite tape 2. The cover plate 5 is used to protect the display panel 1, and the cover plate 5 generally has a high hardness and can effectively resist external physical impacts, such as collision, falling, and extrusion.

[0091] Preferably, the orthographic projection of the cover plate 5 on the display panel 1 is located in the flat area 11 and the bending area 12, so that the display panel 1 can be fully covered to ensure all-round protection of the display panel 1 and improve the protection effect.

[0092] Please continue to refer to Fig. 9 As shown, in one embodiment, the display module 100 further includes a polarizer 6, which is disposed between the cover plate 5 and the display panel 1. The polarizer 6 is helpful in reducing the interference of ambient light on the display effect and improving the contrast. Preferably, the orthographic projection of the polarizer 6 on the display panel 1 is located in the flat area 11 and the bending area 12 to ensure full coverage of the display panel 1.

[0093] Preferably, the display module 100 further includes an optical adhesive 7, which is disposed between the cover plate 5 and the polarizer 6. The optical adhesive 7 is used to bond the polarizer 6 to the display panel 1 while ensuring light transmittance. Preferably, the orthographic projection of the optical adhesive 7 on the display panel 1 is located in the flat area 11 and the bending area 12, ensuring the bonding effect between the polarizer 6 and the display panel 1.

[0094] Based on the same inventive concept, another embodiment of the present application further discloses a display device, which includes the display panel in the above embodiment. Further, the display device includes a mobile phone, VR equipment, computer, television, car display equipment, etc.

[0095] A display device provided in this embodiment has a display module 100 in which the orthographic projection of the first metal layer 23 in the composite tape 2 on the display panel 1 has no overlap with the arc corner area 123, that is, the first metal layer 23 in the arc corner area 123 is removed, thereby avoiding false sticking in the arc corner area 123 due to the greater strength of the first metal layer 23, solving the problem of film layer peeling off after the composite tape 2 in the arc corner area 123 is stuck, avoiding functional defects, improving the display performance of the display module 100, and improving the display effect of the display device.
