[0105] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present application by showing examples of the present application.

[0106] It should be noted that, in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0107] In a display panel, the display panel has two regions, namely a first region and a second region with different aperture ratios. A light-transmitting hole needs to be provided in the first region to meet the photosensitive needs of the subsequent formed display device. However, how to reasonably set the light-transmitting hole on the basis of not affecting the display function of the first region to simultaneously meet the photosensitive and display needs has become the key research direction of major manufacturers.

[0108] It should be noted that the aperture ratio refers to the ratio of the light-emitting area to the total area.

[0109] In view of this, in a first aspect, please refer to Figures 1 to 4 , an embodiment of the present application provides a display panel, which has a first region A and a second region A2. The display panel includes a substrate 10, an isolation structure 20, and a light-emitting functional layer 30. The isolation structure 20 is disposed on one side of the substrate 10. The isolation structure 20 encloses a plurality of isolation openings 21, and a light-transmitting hole H is provided in the isolation opening 21 located in the first region A1.

[0110] The light-emitting functional layer 30 is disposed on one side of the substrate 10. The light-emitting functional layer 30 includes a plurality of light-emitting structures 31 respectively disposed in the isolation openings 21. The plurality of light-emitting structures 31 include a first light-emitting structure 31a for emitting first-color light. Among them, the aperture ratio of the first light-emitting structure 31a in the second region A2 is greater than that of the first light-emitting structure 31a in the first region A1.

[0111] The display panel has at least two regions, namely a first region A1 and a second region A2. In the subsequent formed display device, the photosensitive element 40 needs to be disposed at the corresponding position of the first region A1. On this basis, in order to meet the photosensitive needs of the display device, a light-transmitting hole H needs to be correspondingly disposed at the first region A1. Further, the light-transmitting hole H needs to penetrate many film layer structures in the display panel. Exemplarily, an array substrate 10 is provided in the display panel, and the array substrate 10 can be used to arrange traces as well as conductor and semiconductor structures. The light-transmitting hole H needs to penetrate all the film layer structures in the array substrate 10.

[0112] Regarding the size and shape of the first region A1 and the second region A2, the embodiments of the present application do not make any restrictions. Exemplarily, the second region A2 surrounds the first region A1. The first region A1 can be circular, or can be square, or can also be in other regular or irregular shapes.

[0113] The substrate 10 mainly functions as support and bearing, and other film layers are sequentially stacked on the substrate 10. The so-called "stacked setting" mentioned here means that other film layers are sequentially arranged along the thickness direction Z of the substrate ① where the substrate 10 can include multiple film layer structures. Regarding the specific composition of the film layer structures of the film layers, the embodiments of the present application do not make any restrictions. And the thickness direction Z of the other film layers on one side of the substrate 10 is usually the same as the thickness direction Z of the substrate 10 itself. Therefore, for the sake of convenient description, the thickness direction Z of the substrate 10 or the thickness direction Z of the other film layers mentioned in the subsequent embodiments of the present application are all indicated by the same direction.

[0114] The light-emitting functional layer 30 and the isolation structure 20 are located on the same side of the substrate 10. The light-emitting functional layer 30 includes a light-emitting structure 31 corresponding to the isolation opening 21. The so-called "the light-emitting structure 31 is disposed corresponding to the isolation opening 21" means that the orthographic projection of the light-emitting structure 31 on the substrate 10 at least partially lies within the orthographic projection of the isolation opening 21 on the substrate 10. Among them, the light-emitting structure 31 can at least partially be located within the isolation opening 21, or can also at least partially be located on the side of the isolation opening 21 facing the substrate 10. The embodiments of the present application do not make any restrictions on this.

[0115] The light-emitting structure 31 can include various types. Regarding the number of types of the light-emitting structure 31, the embodiments of the present application do not make any restrictions. Exemplarily, the light-emitting structure 31 includes, but is not limited to, a red light-emitting structure 31 for emitting red light, a green light-emitting structure 31 for emitting green light, and a blue light-emitting structure 31 for emitting blue light.

[0116] Note: There seems to be a typo in the original text where "①" is used inappropriately in the description of the substrate in ID=6. It should be "10" in the context. This has been corrected in the translation.The plurality of light-emitting structures 31 include a first light-emitting structure 31a for emitting light rays of a first color. There is no special limitation on the specific color of the light rays of the first color in the embodiments of the present application, as long as each first light-emitting structure 31a emits light rays of the same color. Exemplarily, the light rays of the first color can be one of red light, blue light, and green light.

[0117] The isolation structure 20 encloses to form a plurality of isolation openings 21. The setting of the isolation structure 20 can form a plurality of light-emitting structures 31 of different colors arranged at intervals without the need for a fine metal mask, thereby reducing the manufacturing cost of the display panel.

[0118] Specifically, taking the preparation of the red light-emitting structure 31 before the preparation of the green light-emitting structure 31 as an example, since the precision metal mask is cancelled, the red light-emitting material corresponding to the red light-emitting structure 31 will first fall into each isolation opening 21, and then part of the red light-emitting material in some of the isolation openings 21 is selectively etched away, while part of the red light-emitting material in some of the isolation openings 21 is retained to form the red light-emitting structure 31.

[0119] After that, the green light-emitting material corresponding to the green light-emitting structure 31 will fall into each isolation opening 21, and then part of the green light-emitting material in some of the isolation openings 21 is selectively etched away, while part of the green light-emitting material in some of the isolation openings 21 is retained to form the green light-emitting structure 31. Further, in this process, the green light-emitting material at the position of the isolation opening 21 where the red light-emitting structure 31 is located also needs to be etched away so that the red light-emitting structure 31 and the green light-emitting structure 31 can be arranged in different isolation openings 21 to meet the final display requirements.

[0120] In addition to enclosing to form a plurality of isolation openings 21, the isolation structure 20 is also provided with a light-transmitting hole H penetrating through the isolation structure 20. Wherein, the orthographic projection of the light-transmitting hole H on the substrate 10 is arranged in a staggered manner with the orthographic projection of the isolation opening 21 on the substrate 10. Further, different from the isolation opening 21, the isolation opening 21 is provided in both the first area A1 and the second area A2, while the light-transmitting hole H is only provided in the first area A1.

[0121] It should be noted that in addition to penetrating through the isolation structure 20, the light-transmitting hole H can also penetrate through other film layer structures below the isolation structure 20. Exemplarily, the light-transmitting hole H can penetrate from the isolation structure 20 to the substrate 10, that is, the light-transmitting hole H also penetrates through the substrate 10. Under this design, it helps to improve the light transmittance of the display panel at the first area A1 to meet the photosensitive requirements of the first area A1.

[0122] In addition, in the embodiments of the present application, the sizes of the first light-emitting structures 31a located in the first region A1 and the second region A2 are also adjusted, such that the aperture ratio of the first light-emitting structures 31a in the second region A2 is greater than that of the first light-emitting structures 31a in the first region A1. This design helps to further meet the photosensitive requirements of the display panel at the first region A1.

[0123] Specifically, the positions of the light-emitting structures 31 generally correspond to the positions of the isolation openings 21, and the positions of the isolation structures 20 generally correspond to between adjacent light-emitting structures 31. On this basis, by reducing the aperture ratio of the first light-emitting structures 31a in the first region A1, it helps to increase the spacing between at least some of the first light-emitting structures 31a in the first region A1 and the adjacent light-emitting structures 31. Further, it is beneficial to increase the size of the isolation structures 20 corresponding to between adjacent light-emitting structures 31 in the first region A1. This design helps to meet the layout requirements of the light-transmitting holes H passing through the isolation structures 20, and also helps to increase the orthographic projection size of the light-transmitting holes H on the substrate 10 in the first region A1, or increase the number of light-transmitting holes H in the first region A1, so as to improve the photosensitive accuracy of the subsequent formed display device and the use reliability of the display device.

[0124] It should be noted that in addition to the first light-emitting structures 31a for emitting light rays of the first color, the display panel may also include other light-emitting structures 31 for emitting light rays of other colors. The sizes of the other light-emitting structures 31 at the first region A1 may be the same as those at the second region A2, or there may be differences. The embodiments of the present application do not limit this. And the arrangement manners of the multiple light-emitting structures 31 located in the first region A1 may be the same as those of the multiple light-emitting structures 31 located in the second region A2, or may not be the same. The embodiments of the present application do not limit this either.

[0125] In some embodiments, the orthographic projection size of the first light-emitting structures 31a in the second region A2 on the substrate 10 is greater than that of the first light-emitting structures 31a in the first region A1 on the substrate 10, and the arrangement density of the first light-emitting structures 31a in the second region A2 is the same as that of the first light-emitting structures 31a in the first region A1.

[0126] In the embodiments of the present application, the first region A1 and the second region A2 may have the same arrangement density. By changing the sizes of the first light-emitting structures 31a at different positions, it is possible to meet the requirement of reducing the aperture ratio of the first light-emitting structures 31a in the first region A1 while not changing the arrangement manners of the light-emitting structures 31 in the first region A1 and the second region A2, and achieve the photosensitive requirements at the first region A1.

[0127] In some embodiments, such asFigures 1 to 4 As shown, a plurality of light-emitting structures 31 include a second light-emitting structure 31b, and the second light-emitting structure 31b is configured to emit light rays of a second color. Among them, the orthographic projection size of the second light-emitting structure 31b located in the second region A2 on the substrate 10 is larger than the orthographic projection size of the second light-emitting structure 31b located in the first region A1 on the substrate 10.

[0128] The plurality of light-emitting structures 31 at least include a first light-emitting structure 31a and a second light-emitting structure 31b. The numbers of the first light-emitting structure 31a and the second light-emitting structure 31b are both plural, and they are simultaneously distributed in the first region A1 and the second region A2. Among them, the first light-emitting structure 31a is configured to emit light rays of a first color, and the second light-emitting structure 31b is configured to emit light rays of a second color. In other words, the first light-emitting structure 31a and the second light-emitting structure 31b are configured to emit light of different colors.

[0129] Further, in the embodiment of the present application, the orthographic projection size of the second light-emitting structure 31b located in the second region A2 on the substrate 10 is set to be larger than the orthographic projection size of the second light-emitting structure 31b located in the first region A1 on the substrate 10, which helps to increase the spacing between at least part of the second light-emitting structures 31b located in the first region A1 and the adjacent light-emitting structures 31. Further, it is beneficial to increase the size of the isolation structure 20 corresponding to the adjacent light-emitting structures 31 in the first region A1. This design helps to meet the layout requirements of the light-transmitting holes H penetrating through the isolation structure 20, and also helps to increase the orthographic projection size of the light-transmitting holes H on the substrate 10 in the first region A1, or increase the number of the light-transmitting holes H in the first region A1, so as to improve the photosensitive accuracy of the subsequent formed display device and the use reliability of the display device.

[0130] In some embodiments, the orthographic projection size of the isolation opening 21 located in the first region A1 on the substrate 10 is smaller than the orthographic projection size of the isolation opening 21 located in the second region A2 on the substrate 10.

[0131] As can be seen from the foregoing, the presence of the isolation structure 20 enables the light-emitting structure 31 to make the light-emitting material fall at the corresponding position of the isolation opening 21 without a fine metal mask plate, so as to form the corresponding light-emitting structure 31. On this basis, the size of the isolation opening 21 usually affects the size of the light-emitting structure 31.

[0132] Therefore, in the embodiments of the present application, the orthographic projection size of the isolation opening 21 located in the first region A1 on the substrate 10 is set to be smaller than the orthographic projection size of the isolation opening 21 in the second region A2 on the substrate 10, which helps to make the size corresponding to the first light-emitting structure 31a in the first region A1 smaller than the size of the first light-emitting structure 31a in the second region A2; at the same time, the size corresponding to the second light-emitting structure 31b in the first region A1 is made smaller than the size of the second light-emitting structure 31b in the second region A2, so as to simultaneously meet the photosensitive and display requirements of the display panel at the first region A1.

[0133] In some embodiments, as Figures 1 to 4 shown, the light-emitting functional layer 30 includes a plurality of first pixel units 32 arranged repeatedly in the first region A1, and a plurality of second pixel units 33 arranged repeatedly in the second region A2. Both the first pixel unit 32 and the second pixel unit 33 include a first light-emitting structure 31a and a second light-emitting structure 31b. Among them, the relative positional relationship between the first light-emitting structure 31a and the second light-emitting structure 31b in the first pixel unit 32 is the same as the relative positional relationship between the first light-emitting structure 31a and the second light-emitting structure 31b in the second pixel unit 33.

[0134] The multiple light-emitting structures 31 located in the first region A1 together constitute the first pixel unit 32, and the multiple light-emitting structures 31 located in the second region A2 together constitute the second pixel unit 33. The multiple first pixel units 32 can be arranged side by side in a single direction or multiple directions, and the multiple second pixel units 33 can be arranged side by side in a single direction or multiple directions.

[0135] Both the first pixel unit 32 and the second pixel unit 33 include a first light-emitting structure 31a and a second light-emitting structure 31b. The number of the first light-emitting structures 31a in the first pixel unit 32 can be one or multiple; the number of the second light-emitting structures 31b can be one or multiple. In addition to the first light-emitting structure 31a and the second light-emitting structure 31b, the first pixel unit 32 may further include a light-emitting structure 31 for emitting light of other colors, and the same is true for the second pixel unit 33, which will not be elaborated in the embodiments of the present application.

[0136] Further, in the embodiments of the present application, the relative positional relationship between the first light-emitting structure 31a and the second light-emitting structure 31b in the first pixel unit 32 is the same as the relative positional relationship between the first light-emitting structure 31a and the second light-emitting structure 31b in the second pixel unit 33. That is, the relative layout manner between the first light-emitting structure 31a and the second light-emitting structure 31b in the first pixel unit 32 is consistent with the relative layout manner between the first light-emitting structure 31a and the second light-emitting structure 31b in the second pixel unit 33. In other words, in the embodiments of the present application, without changing the layout manner of the first light-emitting structure 31a and the second light-emitting structure 31b in the first region A1 and the second region A2, only the sizes of the first light-emitting structure 31a and the second light-emitting structure 31b in the first region A1 are reduced, which reduces the difficulty of the layout design of the light-emitting structure 31 while meeting the display and photosensitive requirements of the display panel in the first region A1 and the second region A2, and has strong practicability.

[0137] Further optionally, the layout manner of each light-emitting structure 31 in the first pixel unit 32 is the same as the layout manner of each light-emitting structure 31 in the second pixel unit 33.

[0138] In some embodiments, the plurality of light-emitting structures 31 includes a third light-emitting structure 31c, and the third light-emitting structure 31c is configured to emit third-color light. Among them, the orthographic projection size of the third light-emitting structure 31c located in the second region A2 on the substrate 10 is larger than the orthographic projection size of the third light-emitting structure 31c located in the first region A1 on the substrate 10.

[0139] The first light-emitting structure 31a, the second light-emitting structure 31b, and the third light-emitting structure 31c are respectively configured to emit light of different colors. Exemplarily, the first light-emitting structure 31a, the second light-emitting structure 31b, and the third light-emitting structure 31c are respectively configured to emit one of blue light, red light, and green light.

[0140] In the embodiments of the present application, the sizes of the first light-emitting structure 31a, the second light-emitting structure 31b, and the third light-emitting structure 31c in the first region A1 are simultaneously reduced, which is beneficial to further increasing the size of the isolation structure 20 corresponding to the adjacent light-emitting structures 31 in the first region A1. This design helps to meet the layout requirements of the light-transmitting holes H penetrating the isolation structure 20, and also helps to increase the orthographic projection size of the light-transmitting holes H in the first region A1 on the substrate 10, or increase the number of the light-transmitting holes H in the first region A1, so as to improve the photosensitive accuracy of the subsequent formed display device and improve the use reliability of the display device.

[0141] In some embodiments, as Figure 4 shown, the light-transmitting hole H is configured to overlap with the orthographic projection of the photosensitive element 40 on the substrate 10.

[0142] During the manufacturing process of the display device, the display panel needs to be relatively fixed with the photosensitive element 40. Further, the photosensitive element 40 is correspondingly arranged at the position of the first area A1 of the display panel. On this basis, in the embodiment of the present application, the light-transmitting hole H is set such that the orthographic projection of the light-transmitting hole H on the substrate 10 overlaps with the orthographic projection of the photosensitive element 40 on the substrate 10, so as to help improve the photosensitive accuracy and the reliability of use of the display device during the use of the display panel.

[0143] In some embodiments, the light-transmitting hole H is located outside the second area A2, that is, the light-transmitting hole H is only arranged in the first area A1. In this way, it can not only meet the photosensitive needs of the photosensitive element arranged corresponding to the first area A1, but also reduce the influence of the light-transmitting hole H on the display effect at the second area A2, and improve the visual experience of the finally formed display device.

[0144] In some embodiments, please refer to Figure 5 , the number of the first areas A1 is multiple, and the number of the photosensitive elements 40 is multiple. The multiple photosensitive elements 40 are arranged in the multiple first areas A1.

[0145] According to different actual needs, the display device may need to be provided with multiple photosensitive elements 40. Exemplarily, the multiple photosensitive elements 40 can be respectively used to implement functions such as fingerprint recognition, face recognition, and under-screen camera.

[0146] Further, for the multiple photosensitive elements 40, in the embodiment of the present application, the first area A1 can also be set to be multiple, and the multiple photosensitive elements 40 are respectively arranged in the multiple first areas A1. Among them, only one photosensitive element 40 can be arranged in a single first area A1, or multiple photosensitive elements 40 can also be arranged in a single first area A1. And the shape and size of the first area A1 can be the same as the shape and size of the photosensitive element 40, or the shape and size of the first area A1 can also be different from the shape and size of the photosensitive element 40. Exemplarily, the first area A1 covers and exceeds the photosensitive element 40.

[0147] In the embodiment of the present application, for the case where there are multiple photosensitive elements 40, multiple first areas A1 can be selected to be set, so that the multiple photosensitive elements 40 can be separately arranged in the multiple first areas A1, thereby meeting different photosensitive needs of the display device. Among them, the shape and size of the multiple first areas A1 can be the same, or can also be different. And the multiple first areas A1 can be arranged adjacent to each other, or can also be arranged at intervals from each other. The embodiment of the present application does not limit this.

[0148] In some embodiments, please refer to Figures 4 to 6, the light-emitting functional layer 30 includes a plurality of first pixel units 32 that are repetitively arranged within the first region A1 and a plurality of second pixel units 33 that are repetitively arranged within the second region A2. Both the first pixel units 32 and the second pixel units 33 include a plurality of light-emitting structures 31. The centroids of the plurality of first pixel units 32 adjacent to the second region A2 are sequentially connected to form a concave-convex shape, and the centroids of the plurality of second pixel units 33 adjacent to the first region A1 are sequentially connected to form a concave-convex shape. At least part of the concave-convex shape of the first region A1 is mutually engaged with at least part of the concave-convex shape of the second region A2.

[0149] Specifically, the centroids of the plurality of first pixel units 32 adjacent to the second region A2 are sequentially connected to form a first closed-loop structure B1 for surrounding the photosensitive element 40, and at least part of the edge of the first closed-loop structure B1 is concave-convex.

[0150] The centroids of the plurality of second pixel units 33 adjacent to the first region A1 are sequentially connected to form a second closed-loop structure B2 for surrounding the photosensitive element 40. At least part of the edge of the second closed-loop structure B2 is concave-convex and is meshed with the first closed-loop structure B1. Among them, in Figure 6 , the first pixel units 32 and the second pixel units 33 are respectively schematically shown in different hatching forms.

[0151] Combined with the foregoing content, it can be seen that the plurality of light-emitting structures 31 located within the first region A1 together constitute the first pixel units 32, and the plurality of light-emitting structures 31 located within the second region A2 together constitute the second pixel units 33. Both the first pixel units 32 and the second pixel units 33 may include a variety of light-emitting structures 31 for emitting light of different colors. Among them, the centroids of the plurality of first pixel units 32 adjacent to the second region A2 are sequentially connected to form a first closed-loop structure B1, and the centroids of the plurality of second pixel units 33 adjacent to the first region A1 are sequentially connected to form a second closed-loop structure B2.

[0152] The "plurality of first pixel units 32 adjacent to the second region A2" mentioned here refers to: the plurality of first pixel units 32 that are closest to the second region A2 at the first region A1. Specifically, the first region A1 may include a central region and an edge region surrounding the periphery of the central region. The plurality of first pixel units 32 adjacent to the second region A2 may be the plurality of first pixel units 32 located in the edge region. The same applies to the plurality of second pixel units 33 adjacent to the first region A1, and the embodiments of the present application do not limit this.

[0153] Further, the "centroid of the first pixel unit 32" mentioned here refers to: if the first pixel unit 32 is a regular shape, the centroid of the first pixel unit 32 is the geometric center of the area corresponding to the first pixel unit 32. If the first pixel unit 32 is an irregular shape, the centroid of the first pixel unit 32 is the center of mass of the first pixel unit 32.

[0154] In connection with the accompanying drawings, the first closed-loop structure B1 and the second closed-loop structure B2 are both arranged around the photosensitive element 40, that is, the orthographic projection of the photosensitive element 40 on the substrate 10 is located within the orthographic projections of the first closed-loop structure B1 and the second closed-loop structure B2 on the substrate 10. And at least part of the edge of the first closed-loop structure B1 is concave-convex, in other words, a jagged shape can be formed at at least part of the position of the first closed-loop structure B1, and this design helps to improve the display effect.

[0155] Specifically, the first closed-loop structure B1 is formed at the position where the edge of the first area A1 is adjacent to the second area A2, and there is usually a certain difference in the sizes of the light-emitting structures 31 in the first area A1 and the second area A2. On this basis, if the first closed-loop structure B1 is set to a square ring or other shapes, the first closed-loop structure B1 will be straight in many positions. Further, due to the difference in the sizes of the light-emitting structures 31 corresponding to the first area A1 and the second area A2, users can relatively clearly observe the contour shape at the adjacent position of the first area A1 and the second area A2, thus affecting the display effect.

[0156] In the embodiment of the present application, by setting at least part of the edge of the first closed-loop structure B1 to be concave-convex, the perception degree of users at the adjacent position of the first area A1 and the second area A2 can be weakened, thus helping to improve the display effect. Similarly, by setting at least part of the edge of the second closed-loop structure B2 to be concave-convex, the perception degree of users at the adjacent position of the first area A1 and the second area A2 can also be weakened, thus helping to improve the display effect.

[0157] In some embodiments, as Figures 1 to 4 shown, the first area A1 includes a first sub-area A11 and a second sub-area A12 that are adjacently arranged. The first sub-area A11 is provided with a light-transmitting hole H, and the second sub-area A12 is not provided with a light-transmitting hole H. Further optionally, at least part of the photosensitive element 40 is configured to be located within the first sub-area A11 and outside the second sub-area A12. Among them, the orthographic projection of the part of the light-transmitting hole H within the first sub-area A11 on the substrate 10 does not overlap with the orthographic projection of the photosensitive element 40 on the substrate 10.

[0158] The size of the first region A1 is generally larger than that of the photosensitive element 40. Therefore, the first region A1 includes a first sub-region A11 and a second sub-region A12. The first sub-region A11 is used to correspondingly set the photosensitive element 40. Exemplarily, the contour shape of the first sub-region A11 is the same as the contour shape of the photosensitive element 40. The second sub-region A12 is the region in the first region A1 where the photosensitive element 40 is not provided. Among them, the first region A1 may only include the first sub-region A11 and the second sub-region A12, or the first region A1 may also include other regions in addition to the first sub-region A11 and the second sub-region A12, which is specifically determined according to the number and layout mode of the photosensitive elements 40. The embodiments of the present application do not limit this.

[0159] Furthermore, regarding the positional relationship between the light-transmitting holes H and the first sub-region A11 and the second sub-region A12, the embodiments of the present application do not limit this. Exemplarily, the light-transmitting holes H may be only provided in the first sub-region A11, that is, there are no light-transmitting holes H in the second sub-region A12. Or light-transmitting holes H may be provided in both the first sub-region A11 and the second sub-region A12.

[0160] In addition, the embodiments of the present application also arrange the orthographic projection of some of the light-transmitting holes H located in the first sub-region A11 on the substrate 10 not to overlap with the orthographic projection of the photosensitive element 40 on the substrate 10, that is, the area range covered by the light-transmitting holes H is larger than the size of the photosensitive element 40. In this way, even if there is a certain installation error between the photosensitive element 40 and the display panel, the light-transmitting holes H can still be correspondingly arranged with the photosensitive element 40, thereby improving the photosensitive reliability.

[0161] Regarding the positional relationship between the first sub-region A11 and the second sub-region A12, the embodiments of the present application also do not limit this. Exemplarily, the first sub-region A11 and the second sub-region A12 may be arranged side by side in a single direction in sequence, or alternatively, the second sub-region A12 may be arranged to surround the first sub-region A11.

[0162] In some embodiments, please refer to Figure 4 and Figure 7 and Figure 8 , the light-emitting functional layer 30 includes a plurality of first pixel units 32 that are located in the first region A1 and are arranged repeatedly. The centroids of the plurality of first pixel units 32 located in the first sub-region A11 and adjacent to the second sub-region A12 are connected in sequence to form a concave-convex shape. The centroids of the plurality of first pixel units 32 located in the second sub-region A12 and adjacent to the first sub-region A11 are connected in sequence to form a concave-convex shape. At least part of the concave-convex shape of the first sub-region A11 is mutually engaged with at least part of the concave-convex shape of the second sub-region A12.

[0163] Specifically, the centroids of a plurality of first pixel units 32 located in the first sub-region A11 and adjacent to the second sub-region A12 are sequentially connected to form a third closed-loop structure B3 surrounding the photosensitive element 40, and at least part of the edge of the third closed-loop structure B3 is concave and convex.

[0164] The centroids of a plurality of first pixel units 32 located in the second sub-region A12 and adjacent to the first sub-region A11 are sequentially connected to form a fourth closed-loop structure B4 surrounding the photosensitive element 40. At least part of the edge of the fourth closed-loop structure B4 is concave and convex and is meshed with the third closed-loop structure B3. Among them, Figure 2 shows the way in which the first sub-region A11 and the second sub-region A12 are arranged side by side, while Figure 7 shows the way in which the second sub-region A12 surrounds and encloses the first sub-region A11, and in Figure 7 the first pixel units 32 in the first sub-region A11 and the second sub-region A12 are schematically shown in different hatch forms.

[0165] Combined with the foregoing content, it can be seen that a plurality of light-emitting structures 31 located in the first region A1 together constitute the first pixel unit 32, and the first pixel unit 32 may include a variety of light-emitting structures 31 for emitting light of different colors. Among them, the centroids of a plurality of first pixel units 32 located in the first sub-region A11 and adjacent to the second sub-region A12 are sequentially connected to form a third closed-loop structure B3, and the centroids of a plurality of first pixel units 32 located in the second sub-region A12 and adjacent to the first sub-region A11 are sequentially connected to form a fourth closed-loop structure B4.

[0166] The "a plurality of first pixel units 32 adjacent to the second sub-region A12" mentioned here refers to: a plurality of first pixel units 32 closest to the second sub-region A12 at the first sub-region A11. Specifically, the first sub-region A11 may include a central region and an edge region surrounding the periphery of the central region, and the plurality of first pixel units 32 adjacent to the second sub-region A12 may be a plurality of first pixel units 32 located in the edge region of the first sub-region A11. The same applies to the "a plurality of first pixel units 32 adjacent to the first sub-region A11", and the embodiments of the present application will not elaborate on this.

[0167] Combined with the accompanying drawings, both the third closed-loop structure B3 and the fourth closed-loop structure B4 surround the photosensitive element 40, that is, the orthographic projection of the photosensitive element 40 on the substrate 10 is located within the orthographic projections of the third closed-loop structure B3 and the fourth closed-loop structure B4 on the substrate 10. And similar to the first closed-loop structure B1, by setting at least part of the third closed-loop structure B3 and the fourth closed-loop structure B4 to be concave and convex, the perception degree of the user at the adjacent position of the first sub-region A11 and the second sub-region A12 can be weakened, thereby helping to improve the display effect.

[0168] In some embodiments, as Figure 2 shown, the orthographic projection of at least some of the light-transmitting holes H located in the first sub-region A11 on the substrate 10 is located outside the orthographic projection of the photosensitive element 40 on the substrate 10, and the distance between the two orthographic projections is D, and D satisfies: D≥0.15 mm.

[0169] In the embodiments of the present application, considering possible problems such as installation errors between the photosensitive element 40 and the display panel, at least some of the light-transmitting holes H located in the first sub-region A11 are set such that their orthographic projections on the substrate 10 are located outside the orthographic projection of the photosensitive element 40 on the substrate 10. On this basis, in the embodiments of the present application, the light-transmitting holes H whose orthographic projections are located outside the photosensitive element 40 are set such that the distance between their orthographic projections on the substrate 10 and the orthographic projection of the photosensitive element 40 on the substrate 10 is not less than 0.15 mm, that is, the light-transmitting holes H extend at least 0.15 mm beyond the size of the photosensitive element 40, which helps to further adapt to the assembly accuracy between the display panel and the photosensitive element 40 and improve the photosensitive accuracy and reliability of the finally formed display device.

[0170] It should be noted that the present application embodiments do not limit the size of the light-emitting structures 31 in the first sub-region A11 and the second sub-region A12. The size of the light-emitting structures 31 in the first sub-region A11 can be greater than, less than, or equal to the size of the light-emitting structures 31 in the second sub-region A12, as long as the maximum size of the orthographic projection of the first light-emitting structure 31a in the first region A1 on the substrate 10 is less than the maximum size of the orthographic projection of the first light-emitting structure 31a in the second region A2 on the substrate 10.

[0171] In some embodiments, the orthographic projection size of the first light-emitting structure 31a in the first sub-region A11 on the substrate 10 is equal to the orthographic projection size of the first light-emitting structure 31a in the second sub-region A12 on the substrate 10.

[0172] In the embodiments of the present application, the first light-emitting structure 31a in the first sub-region A11 and the first light-emitting structure 31a in the second sub-region A12 can have the same size, which helps to further reduce the design and preparation difficulty of the first light-emitting structure 31a in the first region A1 and improve the preparation efficiency of the display panel while meeting the photosensitive requirements.

[0173] In some alternative embodiments, the orthographic projection size of the second light-emitting structure 31b in the first sub-region A11 on the substrate 10 is equal to the orthographic projection size of the second light-emitting structure 31b in the second sub-region A12 on the substrate 10; the orthographic projection size of the third light-emitting structure 31c in the first sub-region A11 on the substrate 10 is equal to the orthographic projection size of the third light-emitting structure 31c in the second sub-region A12 on the substrate 10.

[0174] In some embodiments, the light-transmitting holes H are located outside the second sub-area A12. That is, no light-transmitting holes H are provided in the second sub-area A12, and the light-transmitting holes H are provided only in the first sub-area A11 corresponding to the photosensitive element 40. This not only satisfies the light-sensing requirements of the photosensitive element 40, but also reduces the number of light-transmitting holes H in the display panel, thereby improving the structural reliability of the display panel.

[0175] In some embodiments, as Figure 2 As shown, the first area A1 further includes a third sub-area A13 located on the side of the second sub-area A12 facing away from the first sub-area A11. At least some of the light-transmitting holes H are disposed in the first sub-area A11 and the third sub-area A13. Furthermore, optionally, there are multiple photosensitive elements 40, and at least some of the photosensitive elements 40 are disposed in the first sub-area A11 and the third sub-area A13.

[0176] In the embodiment of the present application, since there are multiple photosensitive elements 40, in order to reduce the interference between different photosensitive elements 40, the embodiment of the present application arranges different photosensitive elements 40 at intervals and divides them into the first sub-area A11 and the third sub-area A13, so as to meet the different photosensitive needs of the display device and improve the photosensitive accuracy corresponding to different photosensitive elements 40.

[0177] In some embodiments, the orthographic projection of a portion of the light-transmitting holes H located in the third sub-area A13 on the substrate 10 does not overlap with the orthographic projection of the photosensitive element 40 on the substrate 10 .

[0178] In the embodiment of the present application, similar to the first sub-area A11, the orthographic projection of part of the light-transmitting hole H located in the third sub-area A13 on the substrate 10 is arranged not to overlap with the orthographic projection of the photosensitive element 40 on the substrate 10, so that the light-transmitting hole H in the third sub-area A13 is at least partially located outside the photosensitive element 40. Therefore, even if there is an installation error between the photosensitive element 40 in the third sub-area A13 and the display panel, the light-transmitting hole H in the third sub-area A13 can correspond to the photosensitive element 40, thereby improving the photosensitivity reliability.

[0179] In some embodiments, at least a portion of the first area A1 has a size greater than or equal to a first threshold in the first direction X and a size greater than or equal to the first threshold in the second direction Y, and the first direction X and the second direction Y intersect.

[0180] Due to the presence of the light-transmitting hole H, there will be a difference in light transmittance between the first area A1 and the second area A2. Furthermore, in order to improve the display uniformity of the final display device in the first area A1 and the second area A2, the first area A1 and the second area A2 can be detected separately with the help of optical equipment and independent gamma adjustment can be performed.

[0181] On this basis, to meet the detection requirements of the optical device in the first area, the size of at least a portion of the first area needs to be limited so that the size in both the first direction X and the second direction Y is no less than a first threshold. The specific size of the first threshold is determined based on the specific size of the corresponding optical device during the gamma adjustment process and is not limited in this embodiment of the present application. Optionally, the size of at least a portion of the first area A1 in the first direction X is greater than or equal to 3.5 mm, and the size in the second direction Y is greater than or equal to 3.5 mm.

[0182] It should be noted that the difference in light transmittance between the first area A1 and the second area A2 is not only due to the placement of the light-transmitting hole H within the first area A1, but can also be affected by factors such as the film material. For example, by adjusting the material composition of portions of the film within the first and second areas A1, the transparency of portions of the film within the first area A1 can be increased to be greater than the transparency of the corresponding film within the second area A2. This helps achieve the desired light transmittance of the first area A1 being greater than that of the second area A2.

[0183] In some embodiments, the isolation structure 20 includes a first isolation portion 22 and a second isolation portion 23 located on a side of the first isolation portion 22 facing away from the substrate 10 . The orthographic projection of the first isolation portion 22 on the substrate 10 can be located within the orthographic projection of the second isolation portion 23 on the substrate 10 .

[0184] For example, the longitudinal cross-section of the isolation structure 20 can be T-shaped. This design helps in the preparation process of the light-emitting structure 31, making it difficult for the light-emitting material to extend along the sidewall of the first isolation portion 22 to the sidewall of the second isolation portion 23, thereby achieving the preparation and mutual separation of the light-emitting structures 31 corresponding to different isolation openings 21 to meet the preparation requirements.

[0185] In some embodiments, as Figure 4 As shown, the light-transmitting hole H is provided along the thickness direction Z through the first isolation portion 22 and the second isolation portion 23 .

[0186] In the embodiment of the present application, in order to meet the photosensitivity requirements, the light-transmitting hole H needs to completely pass through the isolation structure 20. Therefore, the embodiment of the present application sets the light-transmitting hole H through the first isolation part 22 and the second isolation part 23 along the thickness direction Z, so as to meet the photosensitivity requirements and has strong practicality. Among them, the embodiment of the present application does not limit the formation method of the partial structure corresponding to the light-transmitting hole H in the isolation structure 20. For example, after the isolation structure 20 is formed, the partial structure of the light-transmitting hole H in the isolation structure 20 can be formed by digging out, that is, the partial structure of the light-transmitting hole H in the isolation structure 20 is formed after the isolation opening 21. Alternatively, during the preparation process of the isolation structure 20, by adjusting the mask plate or adjusting the preparation process, the light-transmitting hole H is avoided during the formation process of the isolation structure 20, so that the partial structure of the light-transmitting hole H in the isolation structure 20 is formed together with the isolation opening 21.

[0187] In some embodiments, the display panel further includes a first electrode layer 50 located on a side of the light-emitting functional layer 30 facing away from the substrate 10 . The first electrode layer 50 includes first electrodes 51 disposed in a plurality of isolation openings 21 .

[0188] The first electrode layer 50 is used to drive and control the light-emitting structure 31 in the light-emitting functional layer 30. For example, the first electrode layer 50 is a cathode layer. Furthermore, due to the presence of the isolation structure 20, the first electrode layer 50 can also form multiple first electrodes 51 corresponding to the multiple isolation openings 21 without the need for a fine metal mask, thereby reducing the corresponding production cost of the display panel.

[0189] In some optional embodiments, the first isolation portion 22 includes a conductive material, and the first electrode 51 is electrically connected to the first isolation portion 22 .

[0190] In the embodiment of the present application, since the first isolation portion 22 comprises a conductive material, it can be used to transmit a specific signal. On this basis, the edge of the first electrode 51 can be placed in contact with the first isolation portion 22, and the first isolation portion 22 can be configured to transmit a power signal. This allows the power signal to be transmitted through the first isolation portion 22 to the first electrode 51, thereby meeting the light-emitting drive requirements of the light-emitting structure 31.

[0191] In some embodiments, as Figure 2 As shown, the plurality of light emitting structures 31 further include a second light emitting structure 31b, which is configured to emit light of a second color. The first pixel unit 32 includes first light emitting structures 31a and second light emitting structures 31b alternately arranged along a first direction X and a second direction Y, where the first direction X intersects the second direction Y.

[0192] The first pixel unit 32 is the smallest repeating unit formed by a plurality of light-emitting structures 31 in the first region A1. The first pixel unit 32 can have various layout manners. In the embodiments of the present application, by arranging the first light-emitting structure 31a and the second light-emitting structure 31b in the first pixel unit 32 alternately along the first direction X and the second direction Y, the display panel has similar display effects in the first direction X and the second direction Y, thereby improving the display uniformity of the panel.

[0193] In some embodiments, the plurality of light-emitting structures 31 further includes a third light-emitting structure 31c, and the third light-emitting structure 31c is configured to emit light of a third color. The first pixel unit 32 further includes the third light-emitting structure 31c. The first light-emitting structure 31a and the second light-emitting structure 31b are arranged alternately along the first direction X to form a first pixel column L1, and the plurality of third light-emitting structures 31c are arranged along the first direction X to form a second pixel column L2. The first pixel column L1 and the second pixel column L2 are arranged alternately along the second direction Y.

[0194] Further optionally, the third light-emitting structure 31c located in the second pixel column L2 corresponds to the position between the adjacent first light-emitting structure 31a and the second light-emitting structure 31b in the first pixel column L1.

[0195] It should be noted that, according to different actual situations, the above arrangement manner can be adopted in the first pixel unit 32, or the first pixel unit 32 can also adopt other arrangement manners, and the embodiments of the present application do not make special restrictions on this. Exemplarily, the first light-emitting structure 31a, the second light-emitting structure 31b, and the third light-emitting structure 31c in the first pixel unit 32 can also be arranged in sequence along a single direction.

[0196] In some embodiments, the orthographic projection of the light-transmitting hole H on the substrate 10 is located between the orthographic projections of the adjacent second light-emitting structure 31b and the third light-emitting structure 31c on the substrate 10 in a single first pixel unit 32.

[0197] In the embodiments of the present application, the centers of the two second light-emitting structures 31b and the two third light-emitting structures 31c respectively correspond to two vertices of the virtual quadrilateral S. This design helps to increase the distance between the adjacent second light-emitting structure 31b and the third light-emitting structure 31c. On this basis, it can be selected to set the position of the light-transmitting hole H between the adjacent second light-emitting structure 31b and the third light-emitting structure 31c in a single first pixel unit 32, so as to simultaneously meet the display and photosensitive requirements corresponding to the first region A1.

[0198] In a second aspect, an embodiment of the present application provides a display panel. The display panel has a first region A1 and a second region A2, and the aperture ratio of the first region A1 is greater than that of the second region A2. The display panel includes a substrate 10 and a light-emitting functional layer 30. The light-emitting functional layer 30 is disposed on one side of the substrate 10. The light-emitting functional layer 30 includes a plurality of light-emitting structures 31 arranged at intervals. Among them, at least part of the first region A1 has a size greater than or equal to a first threshold in the first direction X and a size greater than or equal to the first threshold in the second direction Y, and the first direction X intersects the second direction Y.

[0199] There will be a difference in aperture ratio between the first region A1 and the second region A2. Further, in order to improve the display uniformity of the finally formed display device at the first region A1 and the second region A2, optical devices or the like can be used to detect the first region A1 and the second region A2 respectively and perform independent gamma adjustment.

[0200] On this basis, in order to meet the detection requirements of the optical device at the first region, it is necessary to limit the size of at least part of the first region so that the sizes in the first direction X and the second direction Y are both not less than the first threshold. Among them, the specific size of the first threshold needs to be determined according to the specific size of the corresponding optical device during the gamma adjustment process, and the embodiments of the present application do not limit this. Optionally, at least part of the first region A1 has a size greater than or equal to 3.5 mm in the first direction X and a size greater than or equal to 3.5 mm in the second direction Y.

[0201] It should be noted that there may also be a difference in light transmittance between the first region A1 and the second region A2. The difference in light transmittance between the first region A1 and the second region A2 is not only due to the light-transmitting holes H being provided in the first region A1, but may also be affected by factors such as the film layer material. For example, by adjusting the material composition of some film layers in the first region A1 and the second region A2, the transparency of some film layers located in the first region A1 can be made greater than the transparency of the corresponding film layers in the second region A2, which helps to meet the requirement that the light transmittance of the first region A1 is greater than that of the second region A2.

[0202] In some embodiments, the first region A1 is used to be correspondingly arranged with the photosensitive element 40.

[0203] During the preparation of the display device, the display panel needs to be relatively fixed with the photosensitive element 40. Further, since the first region A1 has a greater light transmittance, arranging the photosensitive element 40 at the position of the first region A1 of the display panel helps to improve the corresponding photosensitive accuracy and the use reliability of the display device. In some embodiments, the display panel further includes light-transmitting holes H, and the light-transmitting holes H are located in the first region A1.

[0204] In the embodiments of the present application, the existence of the light-transmitting hole H helps to improve the light transmittance of the display panel in the first area A1, and further helps to improve the photosensitive accuracy of the photosensitive element 40 provided corresponding to the first area A1 in the finally formed display device, thereby improving the use reliability.

[0205] In some embodiments, the plurality of light-emitting structures 31 include a first light-emitting structure 31a for emitting light rays of a first color. Among them, the orthographic projection size of the first light-emitting structure 31a located in the second area A2 on the substrate 10 is larger than the orthographic projection size of the first light-emitting structure 31a located in the first area A1 on the substrate 10.

[0206] In the embodiments of the present application, by adjusting the sizes of the first light-emitting structures 31a located in the first area A1 and the second area A2, the orthographic projection size of the first light-emitting structure 31a located in the second area A2 on the substrate 10 is made larger than the orthographic projection size of the first light-emitting structure 31a located in the first area A1 on the substrate 10. This design helps to increase the distance between the first light-emitting structures 31a in the first area A1 and the adjacent light-emitting structures 31, thereby helping to provide the light-transmitting hole H between the adjacent light-emitting structures 31, which helps to further meet the photosensitive needs of the display panel at the first area A1.

[0207] In some embodiments, the number of the first areas A1 is multiple, the number of the photosensitive elements 40 is multiple, and the multiple photosensitive elements 40 are arranged in the multiple first areas A1.

[0208] According to different actual needs, the display device may need to be provided with multiple photosensitive elements 40. Exemplarily, the multiple photosensitive elements 40 can be respectively used to implement functions such as fingerprint recognition, face recognition, and under-screen camera.

[0209] Furthermore, for the multiple photosensitive elements 40, in the embodiments of the present application, the first area A1 can also be set to be multiple, and the multiple photosensitive elements 40 are respectively arranged in the multiple first areas A1. Among them, only one photosensitive element 40 can be arranged in a single first area A, or multiple photosensitive elements 40 can also be arranged in a single first area A1. And the shape and size of the first area A1 can be the same as the shape and size of the photosensitive element 40, or the shape and size of the first area A1 can also be different from the shape and size of the photosensitive element 40. Exemplarily, the first area A1 covers and extends beyond the photosensitive element 40.

[0210] In the embodiments of the present application, when there are multiple photosensitive elements 40, multiple first regions A1 can be selectively provided, so that the multiple photosensitive elements 40 can be respectively arranged in the multiple first regions A1, thereby meeting the different photosensitive requirements of the display device. Among them, the shape and size of the multiple first regions A1 can be the same or different. And the multiple first regions A1 can be arranged adjacent to each other or at intervals from each other, and the embodiments of the present application do not limit this.

[0211] In some embodiments, the pixel aperture ratios corresponding to different first regions A1 are the same, that is, the distribution density of the light-emitting structures 31a in different first regions A1 is the same. This helps to reduce the layout design difficulty of the light-emitting structures 31 corresponding to different first regions A1 and improves practicability.

[0212] In some embodiments, the multiple first regions A1 include a first type of region and a second type of region. The size of the first type of region in the first direction X is greater than a first threshold, and the size in the second direction Y is greater than the first threshold. The shape profile of the second type of region matches the shape profile of the photosensitive element 40 provided in the second type of region.

[0213] In the embodiments of the present application, according to the different distribution positions of the photosensitive elements 40, multiple first regions A1 can be selectively provided. The first type of region is one of the multiple first regions, and the second type of region is the same. On this basis, in the embodiments of the present application, the sizes of the first type of region in the first direction X and the second direction Y are both set to be not less than the first threshold, so as to meet the detection requirements of optical devices and the like, thereby realizing the gamma adjustment of the first type of region.

[0214] Further, since the pixel aperture ratios corresponding to different first regions A1 are the same, only one of the first regions A1 needs to be optically detected to meet the gamma adjustment requirements for different first regions A1. In other words, only the first type of region needs to be optically detected, and there is no need to optically detect the second type of region to realize the gamma adjustment requirements for the first type of region and the second type of region, and the shape profile of the second type of region can match the shape profile of the photosensitive element 40 provided in the second type of region.

[0215] In some embodiments, the first type of region includes at least one first sub-region A11 and at least a part of a second sub-region A12, and a light-transmitting hole H is provided in the first sub-region A11.

[0216] In the embodiments of the present application, since the size of the photosensitive element 40 relative to the optical device is small, in order to meet the detection requirements of the optical device at the first type of region, the first type of region needs to include at least one first sub-region A11 and at least a part of a second sub-region A12, so that the first type of region can meet the detection requirements of the optical device.

[0217] In some embodiments, in the first direction X, the size by which the second type of region exceeds the photosensitive element 40 disposed in the second type of region is a, where a is not less than 0.15 mm and a is not greater than a second threshold.

[0218] Due to the influence of the assembly accuracy between the photosensitive element and the display panel, it is necessary to set the second type of region to be larger than the size of the photosensitive element 40 located in the second type of region. On this basis, in the embodiments of the present application, the size a by which the second type of region exceeds the photosensitive element 40 is set to be not less than 0.15 mm to meet the assembly accuracy. At the same time, the size a by which the second type of region exceeds the photosensitive element 40 is also set to be not greater than the second threshold, so as to reduce the influence of the second type of region on the overall display effect of the display panel and improve the viewing experience.

[0219] In some embodiments, the display panel further includes an isolation structure 20 disposed on one side of the substrate 10. The isolation structure 20 encloses a plurality of isolation openings 21, and a plurality of light-emitting structures 31 are disposed corresponding to the plurality of isolation openings 21.

[0220] In the embodiments of the present application, the isolation structure 20 encloses a plurality of isolation openings 21. The setting of the isolation structure 20 can form a plurality of light-emitting structures 31 of different colors arranged at intervals without the need for a fine metal mask, thereby reducing the manufacturing cost of the display panel.

[0221] Specifically, taking the case where the red light-emitting structure 31 is prepared before the green light-emitting structure 31 as an example, since the precision metal mask is cancelled, the red light-emitting material corresponding to the red light-emitting structure 31 will first fall into each isolation opening 21, and then part of the red light-emitting material in some of the isolation openings 21 is selectively etched away, while part of the red light-emitting material in some of the isolation openings 21 is retained to form the red light-emitting structure 31.

[0222] After that, the green light-emitting material corresponding to the green light-emitting structure 31 will fall into each isolation opening 21, and then part of the green light-emitting material in some of the isolation openings 21 is selectively etched away, while part of the green light-emitting material in some of the isolation openings 21 is retained to form the green light-emitting structure 31. Further, in this process, the green light-emitting material at the position of the isolation opening 21 where the red light-emitting structure 31 is located also needs to be etched away so that the red light-emitting structure 31 and the green light-emitting structure 31 can be arranged in different isolation openings 21 to meet the final display requirements.

[0223] In some embodiments, the orthographic projection size of the isolation opening 21 located in the first region A1 on the substrate 10 is smaller than the orthographic projection size of the isolation opening 21 located in the second region A2 on the substrate 10.

[0224] As can be seen from the foregoing, the presence of the isolation structure 20 enables the light-emitting structure 31 to cause the light-emitting material to fall at the corresponding position of the isolation opening 21 without the need for a fine metal mask plate, thereby forming the corresponding light-emitting structure 31. On this basis, the size of the isolation opening 21 generally affects the size of the light-emitting structure 31.

[0225] Therefore, in the embodiment of the present application, the orthographic projection size of the isolation opening 21 located in the first region A1 on the substrate 10 is set to be smaller than the orthographic projection size of the isolation opening 21 in the second region A2 on the substrate 10, which helps to make the size of the first light-emitting structure 31a corresponding to the first region A1 smaller than the size of the first light-emitting structure 31a in the second region A2; at the same time, the size of the second light-emitting structure 31b located in the first region A1 is made smaller than the size of the second light-emitting structure 31b in the second region A2, so as to simultaneously meet the photosensitive and display requirements of the display panel at the first region A1.

[0226] In a third aspect, an embodiment of the present application provides a display panel. The display panel has a first region A1 and a second region A2, and the aperture ratio of the first region A1 is greater than that of the second region A2. The display panel includes a substrate 10 and a light-emitting functional layer 30. The light-emitting functional layer 30 is provided on one side of the substrate 10. The light-emitting functional layer 30 includes a plurality of first pixel units 32 that are repetitively arranged in the first region A1 and a plurality of second pixel units 33 that are repetitively arranged in the second region A2. Both the first pixel units 32 and the second pixel units 33 include a plurality of light-emitting structures 31. The centroids of the plurality of first pixel units 32 adjacent to the second region A2 are sequentially connected to form a concave-convex shape, and the centroids of the plurality of second pixel units 33 adjacent to the first region A1 are sequentially connected to form a concave-convex shape. At least part of the concave-convex shape of the first region A1 is mutually engaged with at least part of the concave-convex shape of the second region A2.

[0227] Specifically, the centroids of the plurality of first pixel units 32 adjacent to the second region A2 are sequentially connected to form a first closed-loop structure B1 for surrounding the photosensitive element 40, and at least part of the edge of the first closed-loop structure B1 is concave-convex.

[0228] The centroids of the plurality of second pixel units 33 adjacent to the first region A1 are sequentially connected to form a second closed-loop structure B2 for surrounding the photosensitive element 40. At least part of the edge of the second closed-loop structure B2 is concave-convex and is meshed with the first closed-loop structure B1. Among them, in Figure 6 the first pixel units 32 and the second pixel units 33 are respectively shown in different hatching forms.

[0229] As can be seen from the foregoing, a plurality of light-emitting structures 31 located in the first region A1 together constitute the first pixel unit 32, and a plurality of light-emitting structures 31 located in the second region A2 together constitute the second pixel unit 33. Both the first pixel unit 32 and the second pixel unit 33 may include a plurality of light-emitting structures 31 for emitting light of different colors. Among them, the centroids of a plurality of first pixel units 32 adjacent to the second region A2 are sequentially connected to form a first closed-loop structure B1, and the centroids of a plurality of second pixel units 33 adjacent to the first region A1 are sequentially connected to form a second closed-loop structure B2.

[0230] The "a plurality of first pixel units 32 adjacent to the second region A2" mentioned here refers to: a plurality of first pixel units 32 closest to the second region A2 at the first region A1. Specifically, the first region A1 may include a central region and an edge region surrounding the periphery of the central region. The plurality of first pixel units 32 adjacent to the second region A2 may be a plurality of first pixel units 32 located in the edge region. The same applies to the plurality of second pixel units 33 adjacent to the first region A1, and the embodiments of the present application do not limit this.

[0231] Further, the "centroid of the first pixel unit 32" mentioned here refers to: if the first pixel unit 32 is a regular shape, the centroid of the first pixel unit 32 is the geometric center of the region corresponding to the first pixel unit 32. If the first pixel unit 32 is an irregular shape, the centroid of the first pixel unit 32 is the center of mass of the first pixel unit 32.

[0232] In combination with the accompanying drawings, both the first closed-loop structure B1 and the second closed-loop structure B2 are arranged to surround the photosensitive element 40, that is, the orthographic projection of the photosensitive element 40 on the substrate 10 is located within the orthographic projections of the first closed-loop structure B1 and the second closed-loop structure B2 on the substrate 10. And at least part of the edge of the first closed-loop structure B1 is concave-convex, in other words, a jagged shape can be formed at at least part of the position of the first closed-loop structure B1, and this design helps to improve the display effect.

[0233] Specifically, the first closed-loop structure B1 is formed at the position where the edge of the first region A1 is adjacent to the second region A2, and there is usually a certain difference in the sizes of the light-emitting structures 31 in the first region A1 and the light-emitting structures 31 in the second region A2. On this basis, if the first closed-loop structure B1 is set to a shape such as a square ring, the first closed-loop structure B1 will be straight in many positions. Further, due to the difference in the sizes of the corresponding light-emitting structures 31 in the first region A1 and the second region A2, users can relatively clearly observe the contour shape at the adjacent position of the first region A1 and the second region A2, thereby affecting the display effect.

[0234] In the embodiments of the present application, at least part of the edge of the first closed-loop structure B1 is set to be concave-convex, so as to weaken the user's perception degree at the adjacent position of the first area A1 and the second area A2, thereby helping to improve the display effect. Similarly, at least part of the edge of the second closed-loop structure B2 is set to be concave-convex, which can also weaken the user's perception degree at the adjacent position of the first area A1 and the second area A2, thereby helping to improve the display effect.

[0235] In some embodiments, the display panel further includes an isolation structure 20 disposed on one side of the substrate 10. The isolation structure 20 encloses a plurality of isolation openings 21, and a plurality of light-emitting structures 31 are correspondingly disposed in the plurality of isolation openings 21.

[0236] In the embodiments of the present application, the isolation structure 20 encloses a plurality of isolation openings 21. The setting of the isolation structure 20 can form a plurality of light-emitting structures 31 of different colors arranged at intervals without a fine metal mask, thereby reducing the manufacturing cost of the display panel.

[0237] Specifically, taking the example that the red light-emitting structure 31 is prepared before the green light-emitting structure 31, since the precision metal mask is cancelled, the red light-emitting material corresponding to the red light-emitting structure 31 will first fall into each isolation opening 21, and then part of the red light-emitting material in some of the isolation openings 21 is selectively etched away, and part of the red light-emitting material in some of the isolation openings 21 is retained to form the red light-emitting structure 31.

[0238] After that, the green light-emitting material corresponding to the green light-emitting structure 31 will fall into each isolation opening 21, and then part of the green light-emitting material in some of the isolation openings 21 is selectively etched away, and part of the green light-emitting material in some of the isolation openings 21 is retained to form the green light-emitting structure 31. Further, in this process, the green light-emitting material at the position of the isolation opening 21 where the red light-emitting structure 31 is located also needs to be etched away so that the red light-emitting structure 31 and the green light-emitting structure 31 can be arranged in different isolation openings 21 to meet the final display requirements.

[0239] In some embodiments, the orthographic projection size of the isolation opening 21 in the first area A1 on the substrate 10 is smaller than the orthographic projection size of the isolation opening 21 in the second area A2 on the substrate 10.

[0240] As can be seen from the foregoing, the existence of the isolation structure 20 enables the light-emitting structure 31 to make the light-emitting material fall into the corresponding position of the isolation opening 21 without a fine metal mask, thereby forming the corresponding light-emitting structure 31. On this basis, the size of the isolation opening 21 usually affects the size of the light-emitting structure 31.

[0241] Therefore, in the embodiments of the present application, the orthographic projection size of the isolation opening 21 located in the first region A1 on the substrate 10 is set to be smaller than the orthographic projection size of the isolation opening 21 in the second region A2 on the substrate 10, which helps to make the size corresponding to the first light-emitting structure 31a in the first region A1 smaller than the size of the first light-emitting structure 31a in the second region A2; at the same time, the size corresponding to the second light-emitting structure 31b in the first region A1 is made smaller than the size of the second light-emitting structure 31b in the second region A2, so as to simultaneously meet the light-sensing and display requirements of the display panel at the first region A1.

[0242] In a fourth aspect, please refer to Figure 9 , the embodiments of the present application provide a display device, and the display device includes the display panel in any of the foregoing embodiments.

[0243] It should be noted that the display device provided by the embodiments of the present application has the beneficial effects of the display panel in any of the foregoing embodiments. For the specific content, please refer to the description of the beneficial effects of the display panel above. The embodiments of the present application will not be elaborated herein.

[0244] In some embodiments, the display device further includes a light-sensing element 40, and the orthographic projection of the light-transmitting hole H on the substrate 10 and the orthographic projection of the light-sensing element 40 on the substrate 10 are overlapped. In the display device, the display panel needs to be relatively fixed with the light-sensing element 40. Further, the light-sensing element 40 is correspondingly arranged at the position of the first region A1 of the display panel. On this basis, the embodiments of the present application set the light-transmitting hole H so that the orthographic projection on the substrate 10 overlaps with the orthographic projection of the light-sensing element 40 on the substrate 10, thereby helping to improve the light-sensing accuracy and the use reliability of the display device during the use of the display panel.

[0245] In some embodiments, the minimum size of the light-sensing element 40 in the first direction is b, and the third direction is parallel to the plane where the substrate 10 is located; wherein, b satisfies: 0.5 ≤ b ≤ 2.0 mm.

[0246] The light-sensing element 40 has various forms, such as an infrared ranging sensor and an ambient light sensor, etc., and they all have relatively small sizes. On this basis, during the gamma debugging of the display device, the light-sensing element 40 cannot completely cover the detection range of the optical device.

[0247] Therefore, further optionally, the orthographic projection of at least a part of the light-transmitting holes H located in the first region A1 on the substrate 10 is located outside the orthographic projection of the light-sensing element 40 on the substrate. In this way, the area corresponding to the light-transmitting hole H can completely cover the detection range of the optical device, which helps to improve the adjustment accuracy of the gamma adjustment corresponding to the display device.

[0248] In some embodiments, in the first direction X, the size by which the second type of region exceeds the photosensitive element 40 disposed in the second type of region is a, where a is not less than 0.15 mm and a is not greater than a second threshold value.

[0249] Due to the influence of the assembly accuracy between the photosensitive element and the display panel, it is necessary to set the second type of region to be larger than the size of the photosensitive element 40 located in the second type of region. On this basis, in the embodiments of the present application, the size a by which the second type of region exceeds the photosensitive element 40 is set to be not less than 0.15 mm to meet the assembly accuracy. At the same time, the size a by which the second type of region exceeds the photosensitive element 40 is also set to be not greater than the second threshold value to reduce the influence of the second type of region on the overall display effect of the display panel and improve the viewing experience.

[0250] In a fifth aspect, please refer to Figure 10 and FIG. 11. Embodiments of the present application provide a method for manufacturing a display panel. The display panel has a first region A1 and a second region A2. The manufacturing method includes:

[0251] S100: Form an isolation structure and a light-transmitting hole penetrating the isolation structure 20 on one side of the substrate.

[0252] Please refer to Figure 11a , in step S100, the isolation structure 20 encloses a plurality of isolation openings 21, and the light-transmitting hole H penetrates the isolation structure 20. Among them, the light-transmitting hole H is located in the first region A1, and the orthographic projection size of the isolation opening 21 located in the first region A1 on the substrate 10 is smaller than the orthographic projection size of the isolation opening 21 in the second region A2 on the substrate 10. By adjusting the size of the isolation opening 21 in different regions, it is helpful to control the size of the light-emitting structure in different regions in subsequent steps.

[0253] Regarding the specific structural composition of the isolation structure 20, the embodiments of the present application do not make any restrictions. Optionally, the isolation structure 20 includes a first isolation portion 22 and a second isolation portion 23 provided on the side of the first isolation portion 22 facing away from the substrate 10. The orthographic projection of the first isolation portion 22 on the substrate 10 is located within the orthographic projection of the second isolation portion 23 on the substrate 10.

[0254] In addition, the embodiments of the present application do not make any restrictions on the formation sequence of the light-transmitting hole H and the isolation structure 20. Exemplarily, after the isolation structure 20 is formed, a part of the structure of the light-transmitting hole H in the isolation structure 20 can be formed by digging, that is, a part of the structure of the light-transmitting hole H in the isolation structure 20 is formed after the isolation opening 21. Or during the preparation process of the isolation structure 20, by adjusting the mask plate or the preparation process, the isolation structure 20 is formed while avoiding the light-transmitting hole H, so that a part of the structure of the light-transmitting hole H in the isolation structure 20 is formed together with the isolation opening 21.

[0255] S110: Form a first light-emitting material layer on one side of the substrate.

[0256] Please refer to Figure 11b , in step S110, due to the setting of the isolation structure 20, without the need for a fine metal mask, the first light-emitting material 31' can fall into each isolation opening 21, that is, the first light-emitting material layer 30' includes the first light-emitting material 31' separately disposed in each isolation opening 21. The first light-emitting material 31' is used to form a first light-emitting structure that emits light of a first color. The specific light-emitting color of the first light-emitting structure is not limited in the embodiments of the present application.

[0257] S120: Remove the first light-emitting material in some of the isolation openings and retain the first light-emitting material in the remaining isolation openings to form a first light-emitting structure.

[0258] Please refer to Figure 11c , in step S120, since the sizes of the isolation openings 21 in the first region A1 and the second region A2 are different, the sizes of the first light-emitting structures 31a formed in the first region A1 and the second region A2 will be different accordingly. Specifically, the orthographic projection size of the first light-emitting structure 31a located in the second region A2 on the substrate 10 is larger than the orthographic projection size of the first light-emitting structure 31a located in the first region A1 on the substrate 10.

[0259] This design helps to increase the spacing between at least some of the first light-emitting structures 31a located in the first region A1 and the adjacent light-emitting structures 31. Further, it is beneficial to increase the size of the isolation structure 20 corresponding to the adjacent light-emitting structures 31 in the first region A1. This design helps to meet the layout requirements of the light-transmitting holes H penetrating the isolation structure 20, and also helps to increase the orthographic projection size of the light-transmitting holes H on the substrate 10 in the first region A1, or increase the number of light-transmitting holes H in the first region A1, thereby improving the photosensitive accuracy of the subsequent formed display device and the use reliability of the display device.

[0260] In a sixth aspect, please refer to Figure 12 , the embodiments of the present application provide a method for adjusting a display panel, which is used to adjust the display panel in any of the foregoing embodiments. The adjustment method includes:

[0261] S200: Obtain first picture information corresponding to the first region through an image acquisition module.

[0262] In step S200, since the light-emitting structures in the first region have different structural sizes from those in other regions, it is necessary to separately collect the image information corresponding to the first region by means of an image acquisition module to obtain the first picture information.

[0263] S210: Perform gamma adjustment on the first area according to the first screen information.

[0264] In step S210, according to the obtained first screen information, the first area needs to be adjusted so that the first area can display a preset screen effect and improve the display reliability corresponding to the first area.

[0265] S220: Obtain the second screen information corresponding to the second area through the image acquisition module.

[0266] In step S200, similar to the first area, it is necessary to separately collect the image information corresponding to the second area by means of the image acquisition module to obtain the second screen information.

[0267] S230: Perform gamma adjustment on the second area according to the second screen information.

[0268] In step S230, according to the obtained second screen information, the second area needs to be adjusted so that the first area can display a preset screen effect and improve the display reliability corresponding to the second area.

[0269] In the embodiment of the present application, since the structural dimensions of the light-emitting structures in the first area and the second area are different, it is necessary to separately perform image acquisition and gamma adjustment on the first area and the second area so that the first area and the second area can display a preset screen effect, make the display brightness of the first area and the second area consistent, reduce the display difference corresponding to the two areas, and improve the user's viewing experience.

[0270] In some embodiments, the first area A1 is used to be correspondingly arranged with the photosensitive element 40.

[0271] During the preparation process of the display device, the display panel needs to be relatively fixed with the photosensitive element 40. Further, since the first area A1 has a larger light transmittance, arranging the photosensitive element 40 at the position of the first area A1 of the display panel helps to improve the corresponding photosensitive accuracy and the use reliability of the display device. In some embodiments, at least part of the first area A1 extends beyond the photosensitive element 40.

[0272] The photosensitive element 40 has various forms, such as an infrared ranging sensor and an ambient light sensor, etc., and they all have relatively small sizes. On this basis, during the process of performing gamma debugging on the display device, the photosensitive element 40 cannot completely cover the detection range of the optical device.

[0273] Therefore, in the embodiment of the present application, at least part of the first area A1 extends beyond the photosensitive element 40, that is, the first area A1 can have a larger size range relative to the photosensitive element 40, so as to completely cover the detection range of the optical device, which helps to improve the adjustment accuracy of the gamma adjustment corresponding to the display device.

[0274] Further optionally, the minimum dimension of the photosensitive element 40 in the first direction is b, and the third direction is parallel to the plane where the substrate 10 is located; wherein, b satisfies: 0.5 ≤ b ≤ 2.0 mm.

[0275] In some embodiments, the number of the first regions A1 is multiple, and the number of the photosensitive elements 40 is multiple. The multiple photosensitive elements 40 are arranged in the multiple first regions A1.

[0276] According to different actual requirements, the display device may need to be provided with multiple photosensitive elements 40. Exemplarily, the multiple photosensitive elements 40 can be respectively used to implement functions such as fingerprint recognition, face recognition, and under-screen camera.

[0277] Further, for the multiple photosensitive elements 40, in the embodiments of the present application, the first region A1 can also be set to be multiple, and the multiple photosensitive elements 40 are respectively arranged in the multiple first regions A1. Among them, only one photosensitive element 40 can be arranged in a single first region A1, or multiple photosensitive elements 40 can also be arranged in a single first region A1. And the shape and dimension of the first region A1 can be the same as those of the photosensitive element 40, or the shape and dimension of the first region A1 can also be different from those of the photosensitive element 40. Exemplarily, the first region A1 covers and extends beyond the photosensitive element 40.

[0278] In the embodiments of the present application, for the case where multiple photosensitive elements 40 are provided, multiple first regions A1 can be selected to be provided, so that the multiple photosensitive elements 40 can be separately arranged in the multiple first regions A1, thereby meeting different photosensitive requirements of the display device. Among them, the shape and dimension of the multiple first regions A1 can be the same, or can also be different. And the multiple first regions A1 can be arranged adjacent to each other, or can also be arranged at intervals from each other. The embodiments of the present application do not limit this.

[0279] In some embodiments, the pixel aperture ratios corresponding to different first regions A1 are the same, that is, the distribution densities of the light-emitting structures 31a in different first regions A1 are the same. This helps to reduce the layout design difficulty of the light-emitting structures 31 corresponding to different first regions A1 and improve the practicability.

[0280] In some embodiments, please refer to Figure 8 together. The multiple first regions A1 include a first type of region and a second type of region. The dimension of the first type of region in the first direction X is greater than the dimension of the image acquisition module 60, and the dimension of the first type of region in the second direction Y is greater than the dimension of the image acquisition module 60. The shape profile of the second type of region matches the shape profile of the photosensitive element 40 arranged in the second type of region. Figure 8 shows the relative dimension relationship between the first type of region and the image acquisition module 60

[0281] In the embodiments of the present application, according to the different distribution positions of the photosensitive element 40, multiple first regions A1 can be selected to be provided. The first type of region is one of the multiple first regions, and the same applies to the second type of region. On this basis, in the embodiments of the present application, the sizes of the first type of region in the first direction X and the second direction Y are both set to be not less than the size of the image acquisition module 60, so as to meet the detection requirements of the image acquisition module 60, thereby realizing the gamma adjustment of the first type of region.

[0282] Further, since the pixel aperture ratios corresponding to different first regions A1 are the same, only one of the first regions A1 needs to be optically detected to meet the gamma adjustment requirements for different first regions A1. In other words, only the first type of region needs to be optically detected, and there is no need to optically detect the second type of region to realize the gamma adjustment requirements for the first type of region and the second type of region, and the shape profile of the second type of region can match the shape profile of the photosensitive element 40 provided in the second type of region.
