[0026] For ease of understanding the present application, the present application will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present application more thorough and comprehensive.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0028] When describing positional relationships, unless otherwise specified, when an element such as a layer, film, or substrate is referred to as being "on" another element, it can be directly on the other element or there can also be intermediate elements. Further, when a layer is referred to as being "under" another layer, it can be directly below or there can be one or more intermediate elements. It can also be understood that when a layer is referred to as being "between" two layers, it can be the only layer between the two layers or there can also be one or more intermediate elements.

Unless otherwise mentioned, terms in the singular form can include the plural form and should not be understood as having a quantity of one.

[0030] It should be understood that although terms such as "first", "second", etc. can be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, without departing from the scope of the present application, the first element can be referred to as the second element, and similarly, the second element can be referred to as the first element.

For example, "about", "approximately", or "substantially" can mean within one or more standard deviations, which are not defined herein.

[0032] In addition, in the specification, the phrase "planar distribution schematic diagram" refers to the drawing when observing the target part from above, and the phrase "cross-sectional schematic diagram" refers to the drawing when observing the cross-section intercepted by vertically cutting the target part from the side.

[0033] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the various elements are only drawn by way of example in the drawings and are not necessarily drawn to the actual scale.

[0034] As described in the background art section, in the related art, in order to improve the side strength of the display panel, an integrated cutting method is usually adopted to prepare the display panel, that is, in the related art, when preparing the display panel, the optical glue layer in the bending area of the display panel is cut. During the actual use of the display panel, the bending area of the display panel will be repeatedly bent. Due to the cutting defects of the previous laser cutting, problems such as thermal damage, cutting step difference, and bubbles will occur at the edge of the bending area of the display panel, which will further lead to problems such as delamination and fracture in the bending area, resulting in abnormal display of the display panel.

[0035] Based on the above technical problems, the inventors have found through research that the color shift phenomenon at large viewing angles can be improved by providing a light scattering layer on the light-emitting side of the display substrate. Based on this, the inventors have further developed the technical solution of the embodiments of the present application. Specifically, the display panel to be cut provided by the embodiments of the present application includes: a display layer and an optical adhesive layer, and the optical adhesive layer is located on one side of the display layer; the display panel to be cut further includes: a bending area, a non-bending area, a display area, a non-display area, and a cutting path; the bending area is configured to be bent along an axis extending in a first direction, the non-bending area is located on at least one side of the bending area in a second direction, the non-display area at least partially surrounds the display area, and the cutting path is located in the non-display area and surrounds the display area; wherein, the optical adhesive layer includes a first optical adhesive layer and a second optical adhesive layer arranged in the same layer, the first optical adhesive layer at least covers a part of the bending area in the second direction, the second optical adhesive layer is located in a part of the non-bending area, the first optical adhesive layer has a first end and a second end in the first direction, and the first end and the second end are respectively located between the cutting path and the display area. By adopting the above technical solution, by making the two ends of the first optical adhesive layer retract between the cutting path and the display area, it is possible to avoid cutting the optical adhesive in the bending area, thereby avoiding cutting defects in the bending area of the display panel, and thus improving the bending ability of the display panel and the display performance of the display panel.

[0036] The above is the core idea of the present application. Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0037] In an exemplary embodiment, please refer to Figure 1 and Figure 2 , the present application provides a display panel to be cut, and the display panel to be cut includes: a bending area 111, a non-bending area 112, a display area AA, a non-display area NA, and a cutting path 113; the bending area 111 is configured to be bent along an axis 11 extending in a first direction, the non-bending area 112 is located on at least one side of the bending area 111 in a second direction, the non-display area NA at least partially surrounds the display area, and the cutting path 113 is located in the non-display area NA and surrounds the display area AA.

[0038] The display panel to be cut further includes: a display layer 10 and an optical adhesive layer 20. The optical adhesive layer 20 is located on one side of the display layer 10 in the third direction. Among them, the optical adhesive layer 20 includes a first optical adhesive layer 201 and a second optical adhesive layer 202 arranged in the same layer. The first optical adhesive layer 201 covers at least part of the bending area in the second direction, and the second optical adhesive layer 202 is located in at least part of the non-bending area 112. The first optical adhesive layer 201 has a first end and a second end in the first direction, and the first end and the second end are respectively located between the cutting channel 113 and the display area AA.

[0039] Among them, the first direction is Figure 1 and Figure 2 the X-axis direction shown in Figure 1 the Y-axis direction shown in Figure 2 the Z-axis direction shown in, and the first direction, the second direction and the third direction intersect with each other.

[0040] In this embodiment, Figure 1 the part outlined by the dashed line in Figure 1 is the display area AA of the display panel to be cut. The non-display area NA is arranged around the display area NA. Specifically, the non-display area NA is divided into a first non-display area NA1 and a second non-display area NA2 by the cutting channel 113. The first non-display area NA1 surrounds the second non-display area NA2, and the second non-display area NA2 surrounds the display area AA. Figure 1 The area between the two dashed lines with equal lengths and extending in the first direction in

[0041] The display panel to be cut provided by the embodiment of the present application includes a display layer and an optical glue layer located on one side of the display layer, and further includes a bending area, a non-bending area, a display area, a non-display area, and a cutting path. The bending area is configured to be bent along an axis extending in the first direction. The non-bending area is located on at least one side of the bending area in the second direction. The non-display area at least partially surrounds the display area. The cutting path is located in the non-display area and surrounds the display area. The optical glue layer includes a first optical glue layer and a second optical glue layer arranged in the same layer. In the present application, the first optical glue layer is provided to cover at least a part of the bending area in the second direction, and the second optical glue layer is located in a part of the non-bending area. The first optical glue layer has a first end and a second end in the first direction, and the first end and the second end are respectively located between the cutting path and the display area. Thus, when the display panel to be cut is cut into a display panel, it is possible to avoid cutting the optical glue in the bending area, and further avoid problems such as thermal damage, cutting step difference, and air bubbles in the optical glue in the bending area, resulting in a reduction in the interfacial peeling force of the optical glue in the bending area. Therefore, problems such as delamination and fracture of the bending area can be effectively avoided, and the bending ability of the display panel can be improved.

[0042] In an exemplary embodiment, please continue to refer to Figure 1 , the display panel to be cut has a first end and a second end in the first direction, and the cutting path includes a first sub-path and a second sub-path extending in the second direction;

[0043] The distance between the positive projection of the first end of the first optical glue layer 201 on the target plane and the positive projection of the first end of the display panel to be cut on the target plane is greater than the distance between the positive projection of the first sub-path of the cutting path 113 on the target plane and the positive projection of the first end of the display panel to be cut on the target plane.

[0044] The distance between the positive projection of the second end of the first optical glue layer 201 on the target plane and the positive projection of the second end of the display panel to be cut on the target plane is greater than the distance between the positive projection of the second sub-path of the cutting path 113 on the target plane and the positive projection of the second end of the display panel to be cut on the target plane.

[0045] Wherein, the target plane includes the plane where the display layer 10 is located. The first sub-path and the second sub-path of the cutting path 113 are respectively located on both sides of the bisector of the bending area in the second direction, and the first sub-path of the cutting path 113 is the sub-path of the cutting path 113 close to the first end of the display panel to be cut, and the second sub-path of the cutting path 113 is the sub-path of the cutting path 113 close to the second end of the display panel to be cut.

[0046] It can be understood that, in order to prevent the first optical adhesive layer 201 of the present application from participating in the cutting when the display panel to be cut is cut, the distance between the positive projection of the first sub-track of the cutting channel 113 on the target plane and the positive projection of the first end of the display panel to be cut on the target plane, and the distance between the positive projection of the second sub-track of the cutting channel 113 on the target plane and the positive projection of the second end of the display panel to be cut on the target plane can be determined in the design stage. Then, when the optical adhesive layer 20 is formed on the display layer 10, it is controlled that the distance between the positive projection of the first end of the first optical adhesive layer 201 on the target plane and the positive projection of the first end of the display panel to be cut on the target plane is greater than the distance between the positive projection of the first sub-track of the cutting channel 113 on the target plane and the positive projection of the first end of the display panel to be cut on the target plane, and it is controlled that the distance between the positive projection of the second end of the first optical adhesive layer 201 on the target plane and the positive projection of the second end of the display panel to be cut on the target plane is greater than the distance between the positive projection of the second sub-track of the cutting channel 113 on the target plane and the positive projection of the second end of the display panel to be cut on the target plane, so that the first optical adhesive layer 201 can be located between the cutting channel 113 and the display area AA, and the first optical adhesive layer 201 can be prevented from participating in the cutting.

[0047] In an exemplary embodiment, please refer to Figure 1 and Figure 3 , the display area AA has a first side and a second side in the first direction. The first end of the first optical adhesive layer 201 protrudes beyond the first side of the display area AA, or the first end of the first optical adhesive layer 201 is flush with the first side of the display area AA; the second end of the first optical adhesive layer 201 protrudes beyond the second side of the display area AA, or the second end of the first optical adhesive layer 201 is flush with the second side of the display area AA.

[0048] Wherein, the first side and the second side of the display area AA are respectively located on both sides of the bisector of the bending area 111 in the second direction, and the first side of the display area AA is the side of the display area AA close to the first end of the display panel to be cut, and the first side of the display area AA is the side of the display area AA close to the second end of the display panel to be cut.

[0049] In this application, in order to ensure the display performance of the display area AA of the display panel, it is necessary to provide an optical adhesive in the overlapping part of the orthographic projection of the display area AA on the target plane and the orthographic projection of the bending area 111 on the target plane. Therefore, in this application, the first end of the first optical adhesive layer 201 can be flush with the first side of the display area AA or protrude outward from the first side of the display area AA without entering the display area AA; similarly, the second end of the first optical adhesive layer 201 can be flush with the second side of the display area AA or protrude outward from the second side of the display area AA without entering the display area AA. This is to ensure the display performance of the display panel.

[0050] In an exemplary embodiment, please refer to Figure 1 and Figure 4 , the first optical adhesive layer 201 has a third end and a fourth end in the second direction, the display panel to be cut has a third end and a fourth end in the second direction, and the bending area 111 has a third side and a fourth side in the second direction.

[0051] The distance between the orthographic projection of the third end of the first optical adhesive layer 201 on the target plane and the orthographic projection of the third end of the display panel to be cut on the target plane is less than or equal to the distance between the orthographic projection of the third side of the bending area 111 on the target plane and the orthographic projection of the third end of the display panel to be cut on the target plane.

[0052] The distance between the orthographic projection of the fourth end of the first optical adhesive layer 201 on the target plane and the orthographic projection of the fourth end of the display panel to be cut on the target plane is less than or equal to the distance between the orthographic projection of the fourth side of the bending area 111 on the target plane and the orthographic projection of the fourth end of the display panel to be cut on the target plane.

[0053] In practical applications, the third side and the fourth side of the bending area 111 are respectively located on both sides of the axis 11, and the third side is the side of the bending area 111 close to the third end of the display panel to be cut, and the fourth side is the side of the bending area 111 close to the fourth end of the display panel to be cut.

[0054] In this application, when forming the optical adhesive layer 20 on the display layer 10, it is only necessary to ensure that the optical adhesive corresponding to the overlapping part of the orthographic projection of the display area AA on the target plane and the orthographic projection of the bending area 111 on the target plane does not participate in the cutting. The width of the first optical adhesive layer 201 in the second direction can be greater than or equal to the width of the bending area 111 in the second direction.

[0055] Preferably, the width of the first optical glue layer 201 in the second direction is equal to the width of the bending area 111 in the second direction, that is, the distance between the positive projection of the third end of the first optical glue layer 201 on the target plane and the positive projection of the third end of the display panel to be cut on the target plane is equal to the distance between the positive projection of the third side of the bending area 111 on the target plane and the positive projection of the third end of the display panel to be cut on the target plane; the distance between the positive projection of the fourth end of the first optical glue layer 201 on the target plane and the positive projection of the fourth end of the display panel to be cut on the target plane is equal to the distance between the positive projection of the fourth side of the bending area 111 on the target plane and the positive projection of the fourth end of the display panel to be cut on the target plane. So that the optical glue located in the non-bending area 112 can participate in the cutting as much as possible to improve the module strength of the display panel.

[0056] In an exemplary embodiment, please refer to Figure 5 , the second optical glue layer 202 has a first end and a second end in the first direction.

[0057] The distance between the positive projection of the first sub-channel of the cutting channel 113 on the target plane and the positive projection of the first end of the display panel to be cut on the target plane is less than or equal to the distance between the positive projection of the first end of the second optical glue layer 202 on the target plane and the positive projection of the first end of the display panel to be cut on the target plane.

[0058] The distance between the positive projection of the second sub-channel of the cutting channel 113 on the target plane and the positive projection of the second end of the display panel to be cut on the target plane is less than or equal to the distance between the positive projection of the second end of the second optical glue layer 202 on the target plane and the positive projection of the second end of the display panel to be cut on the target plane.

[0059] In this embodiment, the first end of the second optical glue layer 202 can be located between the first sub-channel of the cutting channel 113 and the first end of the display panel to be cut, and the second end of the second optical glue layer 202 can be located between the second sub-channel of the cutting channel 113 and the second end of the display panel to be cut, so as to ensure that the first end and the second end of the second optical glue layer 202 can participate in the cutting. By enabling the first end and the second end of the second optical glue layer 202 to participate in the cutting, the module strength of the display panel can be ensured and the impact resistance of the display panel can be improved.

[0060] In an exemplary embodiment, please refer to Figure 6 , the cutting channel 113 includes a third sub-channel and a fourth sub-channel extending in the first direction. The positive projections of the third sub-channel and the fourth sub-channel of the cutting channel 113 on the target plane fall within the positive projection of the optical glue layer on the target plane.

[0061] It can be understood that in order to ensure that the optical adhesive layer 20 can also participate in cutting in the second direction, in this application, the optical adhesive layer 20 is arranged to cover the third sub-track and the fourth sub-track of the cutting track 113 in the first direction, so as to improve the module strength of the display panel.

[0062] In an exemplary embodiment, please refer to Figure 7 , the shapes of the first end and the second end of the first optical adhesive layer 201 in the orthographic projection on the target plane are respectively one of a straight line type, an arc type, a wavy line type, and a serrated line type.

[0063] In this application, the shapes of the first end and the second end of the first optical adhesive layer 201 in the orthographic projection on the target plane are not limited, as long as when the display panel to be cut is being cut, the first end and the second end of the first optical adhesive layer 201 do not participate in cutting, and the first optical adhesive layer 201 is located between the cutting track 113 and the display area AA. The shapes of the first end and the second end of the first optical adhesive layer 201 in the orthographic projection on the target plane can be specifically determined by those skilled in the art according to needs during the production and design process of the display panel. For example, the shapes of the first end and the second end of the first optical adhesive layer 201 in the orthographic projection on the target plane can be Figure 7 the arc type shown. The shapes of the first end and the second end of the first optical adhesive layer 201 in the orthographic projection on the target plane can include but are not limited to a straight line type, an arc type, a wavy line type, and a serrated line type.

[0064] In an exemplary embodiment, please refer to Figure 8 and Figure 9 , the display panel to be cut further includes: a cover plate 30, the cover plate 30 is located on the side of the optical adhesive layer 20 away from the display layer 10, and the orthographic projection of the cover plate 30 on the target plane covers the orthographic projection of the optical adhesive layer 20 on the target plane.

[0065] Among them, Figure 8 is a schematic cross-sectional view of the third end or the fourth end of the display panel to be cut in the second direction in an example, Figure 9 is a schematic cross-sectional view of the display panel to be cut at the axis 11 in an example. It can be understood that since the first optical adhesive layer 201 is located between the cutting track 113 and the display area AA, the size of the first optical adhesive layer 201 in the first direction is smaller than the size of the cover plate 30 in the first direction.

[0066] In an exemplary embodiment, please refer to Figure 10 , this application provides a method for manufacturing a display panel, and the method includes:

[0068] The display panel to be cut includes a display layer and an optical adhesive layer. The optical adhesive layer is located on one side of the display layer.
