[0032] Furthermore, in the instruction manual, the phrase "planar distribution diagram" refers to the diagram when the target part is viewed from above, and the phrase "cross-sectional diagram" refers to the diagram when the target part is viewed from the side as a cross-section taken by vertically cutting the target part.

[0033] Furthermore, the accompanying drawings are not drawn to a 1:1 scale, and the relative dimensions of the components are shown in the drawings only as examples and not necessarily to actual scale.

[0034] As described in the background section, in order to improve the side strength of the display panel, the display panel is usually manufactured by integral cutting. That is, in the related technologies, the optical adhesive layer of the bending area of ​​the display panel is cut during the manufacturing process. In 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 laser cutting in the early stage, the edge of the bending area of ​​the display panel will suffer from heat damage, cutting stage difference, bubbles and other problems. This will make the bending area prone to delamination, breakage and other problems, resulting in abnormal display of the display panel.

[0035] Based on the aforementioned technical problems, the inventors discovered that providing a light scattering layer on the light-emitting side of the display substrate can improve color shift at large viewing angles. Based on this, the inventors further developed the technical solution of the embodiments of this application. Specifically, the display panel to be cut provided in the embodiments of this application includes: a display layer and an optical adhesive layer, the optical adhesive layer being located on one side of the display layer; the display panel to be cut also includes: a bending area, a non-bending area, a display area, a non-display area, and a cutting track; 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 track 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 disposed in the same layer, the first optical adhesive layer at least covers a portion of the bending area in the second direction, the second optical adhesive layer is located in a portion of the non-bending area, the first optical adhesive layer has a first end and a second end in the first direction, the first end and the second end are respectively located between the cutting track and the display area. By adopting the above technical solution, by making the two ends of the first optical adhesive layer recessed between the cutting channel and the display area, the optical adhesive in the bending area can be avoided from being cut, thereby avoiding cutting defects in the bending area of ​​the display panel, thus improving the bending ability of the display panel and improving the display performance of the display panel.

[0036] The above is the core idea of ​​this application. The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] In one exemplary embodiment, please refer to the following: Figure 1 and Figure 2 This application provides a display panel to be cut, 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 channel 113; the bending area 111 is configured to be bent about 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 channel 113 is located in the non-display area NA and surrounds the display area AA.

[0038] The display panel to be cut also 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 a third direction. The optical adhesive layer 20 includes a first optical adhesive layer 201 and a second optical adhesive layer 202 disposed in the same layer. The first optical adhesive layer 201 covers at least a portion of the bending area in a second direction. The second optical adhesive layer 202 is located in at least a portion of the non-bending area 112. The first optical adhesive layer 201 has a first end and a second end in a first direction. The first end and the second end are respectively located between the cutting channel 113 and the display area AA.

[0039] The first direction is Figure 1 and Figure 2 The X-axis direction shown is the second direction. Figure 1 The Y-axis direction shown is the third direction. Figure 2 The Z-axis direction shown in the figure intersects with the first direction, the second direction, and the third direction.

[0040] In this embodiment, Figure 1 The part outlined by the dashed line is the display area AA of the display panel to be cut. The non-display area NA is set 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 two equal-length dashed lines extending along the first direction is the bending area 111 of the display panel to be cut. A dashed line extending along the first direction and longer than the two dashed lines is the axis 11. The non-bending area 112 is located on both sides of the bending area 111 in the second direction. Figure 1 As can be seen, the first optical adhesive layer 201 can be located in the bending area 111, and the first end and the second end of the first optical adhesive layer 201 in the first direction are respectively located between the cutting path 113 and the display area AA. Therefore, when the display panel to be cut is cut along the cutting path 113 to prepare the display panel, the first end and the second end of the first optical adhesive layer 201 will not participate in the cutting, and thus the first end and the second end of the first optical adhesive layer 201 will not suffer from cutting defects such as heat damage, cutting step difference, and bubbles. When the display panel prepared in this way is repeatedly bent during subsequent use, its bending area is not prone to delamination, breakage, or other problems, thereby ensuring that the display panel has good bending ability.

[0041] The display panel to be cut provided in this application embodiment includes a display layer and an optical adhesive layer located on one side of the display layer. It also includes a bending area, a non-bending area, a display area, a non-display area, and a cutting channel. 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. The cutting channel is located in the non-display area and surrounds the display area. The optical adhesive layer includes a first optical adhesive layer and a second optical adhesive layer disposed in the same layer. In this application, the first optical adhesive layer covers at least part of the bending area in the second direction, and the second optical adhesive layer is located in part of the non-bending area. The first optical adhesive layer has a first end and a second end in the first direction. The first end and the second end are respectively located between the cutting channel and the display area. Therefore, when the display panel to be cut is manufactured into a display panel, the optical adhesive in the bending area can be avoided from being cut, thereby avoiding problems such as heat damage, cutting step difference, and bubbles in the optical adhesive in the bending area, which would lead to a decrease in the peeling force of the optical adhesive interface in the bending area. This can effectively avoid problems such as delamination and breakage in the bending area and improve the bending ability of the display panel.

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

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

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

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

[0046] It is understood that in order to ensure that the first optical adhesive layer 201 of this application does not participate in the cutting when the display panel to be cut is cut, the distance between the orthographic projection of the first sub-path of the cutting path 113 on the target plane and the orthographic projection of the first end of the display panel to be cut on the target plane, and the distance between the orthographic projection of the second sub-path of the cutting path 113 on the target plane and the orthographic projection of the second end of the display panel to be cut on the target plane can be determined during the design stage. Subsequently, when forming the optical adhesive layer 20 on the display layer 10, the distance between the orthographic projection of the first end of the first optical adhesive layer 201 on the target plane and the orthographic projection of the first end of the display panel to be cut on the target plane is controlled to be greater than the distance between the orthographic projection of the first sub-track of the cutting track 113 on the target plane and the orthographic projection of the first end of the display panel to be cut on the target plane. Additionally, the distance between the orthographic projection of the second end of the first optical adhesive layer 201 on the target plane and the orthographic projection of the second end of the display panel to be cut on the target plane is controlled to be greater than the distance between the orthographic projection of the second sub-track of the cutting track 113 on the target plane and the orthographic projection of the second end of the display panel to be cut on the target plane. This ensures that the first optical adhesive layer 201 is located between the cutting track 113 and the display area AA, preventing the first optical adhesive layer 201 from participating in the cutting process.

[0047] In one exemplary embodiment, please refer to Figure 1 and Figure 3 The display area AA has a first side and a second side in a first direction. The first end of the first optical adhesive layer 201 protrudes outward from 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 outward from 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] The first side and the second side of the display area AA are 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 near 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 near the second end of the display panel to be cut.

[0049] In this application, to ensure the display performance of the display area AA of the display panel, the portion where the orthographic projection of the display area AA on the target plane overlaps with the orthographic projection of the bending area 111 on the target plane needs to be covered with optical adhesive. 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 beyond 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 beyond the second side of the display area AA without entering the display area AA, thus ensuring the display performance of the display panel.

[0050] In one 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 onto the target plane and the orthographic projection of the third end of the display panel to be cut onto the target plane is less than or equal to the distance between the orthographic projection of the third side of the bending area 111 onto the target plane and the orthographic projection of the third end of the display panel to be cut onto the target plane.

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

[0053] In the application, the third and fourth sides of the bending area 111 are located on both sides of the axis 11, and the third side is the side of the bending area 111 near the third end of the display panel to be cut, and the fourth side is the side of the bending area 111 near 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 ensured that the optical adhesive corresponding to the portion where the orthographic projection of the display area AA on the target plane overlaps with 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 adhesive layer 201 in the second direction is equal to the width of the bending region 111 in the second direction. That is, the distance between the orthographic projection of the third end of the first optical adhesive layer 201 onto the target plane and the orthographic projection of the third end of the display panel to be cut onto the target plane is equal to the distance between the orthographic projection of the third side of the bending region 111 onto the target plane and the orthographic projection of the third end of the display panel to be cut onto the target plane; the distance between the orthographic projection of the fourth end of the first optical adhesive layer 201 onto the target plane and the orthographic projection of the fourth end of the display panel to be cut onto the target plane is equal to the distance between the orthographic projection of the fourth side of the bending region 111 onto the target plane and the orthographic projection of the fourth end of the display panel to be cut onto the target plane. This ensures that as much of the optical adhesive located in the non-bending region 112 as possible participates in the cutting, thereby improving the module strength of the display panel.

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

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

[0058] The distance between the orthographic projection of the second sub-path of the cutting path 113 on the target plane and the orthographic projection of the second end of the display panel to be cut on the target plane is greater than or equal to the distance between the orthographic projection of the second end of the second optical adhesive layer 202 on the target plane and the orthographic 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 adhesive layer 202 can be located between the first sub-track of the cutting track 113 and the first end of the display panel to be cut, and the second end of the second optical adhesive layer 202 can be located between the second sub-track of the cutting track 113 and the second end of the display panel to be cut, so as to ensure that the first and second ends of the second optical adhesive layer 202 can participate in the cutting. By enabling the first and second ends of the second optical adhesive layer 202 to participate in the cutting, the module strength of the display panel can be guaranteed, and the impact resistance of the display panel can be improved.

[0060] In one exemplary embodiment, please refer to Figure 6 The cutting channel 113 includes a third sub-channel and a fourth sub-channel extending along the first direction. The orthographic projection of the third and fourth sub-channels of the cutting channel 113 onto the target plane falls into the orthographic projection of the optical adhesive layer onto the target plane.

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

[0062] In one exemplary embodiment, please refer to Figure 7 The shapes of the first end and the second end of the first optical adhesive layer 201 projected onto the target plane are respectively one of the following: straight line, arc, wavy line, and sawtooth line.

[0063] In this application, the shape of the first end and the second end of the first optical adhesive layer 201 projected onto the target plane is not limited, as long as the first end and the second end of the first optical adhesive layer 201 do not participate in the cutting when the display panel to be cut is being cut, and the first optical adhesive layer 201 is located between the cutting path 113 and the display area AA. The shape of the first end and the second end of the first optical adhesive layer 201 projected onto the target plane can be specifically determined by relevant personnel during the production design process of the display panel as needed. For example, the shape of the first end and the second end of the first optical adhesive layer 201 projected onto the target plane can be... Figure 7 The arc shape shown. The shape of the first end and the second end of the first optical adhesive layer 201 projected onto the target plane can be, but is not limited to, a straight line, an arc shape, a wavy line, or a sawtooth line.

[0064] In one exemplary embodiment, please refer to Figure 8 and Figure 9 The display panel to be cut also includes a cover plate 30, which 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] in, Figure 8 This is a schematic cross-sectional view of the third or fourth end of a display panel to be cut in the second direction, as shown in an example. Figure 9 This is a schematic cross-sectional view of the display panel to be cut at axis 11 in an example. It can be understood that since the first optical adhesive layer 201 is located between the cutting channel 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 one exemplary embodiment, please refer to Figure 10 This application provides a method for manufacturing a display panel, the method comprising:
