In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present application and are not configured to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details.

[0098] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0099] It should be understood that when describing the structure of a component, when a layer or a region is referred to as being "on" or "over" another layer or another region, it may mean that it is directly on the other layer or another region, or that other layers or regions are included between it and the other layer or another region. Moreover, if the component is turned over, the layer or a region will be "below" or "beneath" another layer or another region.

[0100] In the related art, a light sensor is projected onto one side of a display panel. The low light transmittance of the display panel will reduce the amount of light received by the light sensor, thereby affecting the operation of the light sensor. The inventors have found that a light-transmitting area can be provided between adjacent light-emitting parts to increase the light transmittance of the area corresponding to the light sensor. However, the light-transmitting area will occupy the area where the light-emitting parts can be distributed, thereby reducing the light brightness of the display panel.

[0101] In order to solve the above problems, embodiments of the present application provide a display panel and a display device. Various embodiments of the display panel and the display device will be described below in conjunction with the accompanying drawings.

Light entering the display panel from one side of the display panel can be emitted from the other side of the display panel through the light-transmitting opening 24, and the light sensor located on one side of the first display area AA1 receives the light to realize photoelectric conversion. The light sensor can specifically be an infrared sensor, a camera, etc.

[0106] The plurality of light emitting parts 31 may include light emitting parts 31 capable of emitting light of different colors. For example, it may be a red light emitting part capable of emitting red light, a green light emitting part capable of emitting green light, and a blue light emitting part capable of emitting blue light. The number of the limited openings 23 may be determined as required.

[0107] The display panel may further include a non-display area NA arranged around the second display area AA2, the light emitting portion 31 may be distributed in the first display area AA1 and the second display area AA2, and the light emitting portion 31 may not be arranged in the non-display area NA, so that the non-display area NA is not used for light-emitting display. The light-transmitting opening 24 may not be arranged in the second display area AA2, so that the second display area AA2 may be provided with more limiting openings 23, more light emitting portions 31, or large-sized limiting openings 23, large-sized light emitting portions 31 per unit area compared to the first display area AA1, so as to improve the pixel arrangement density of the second display area AA2, or the light emitting brightness of the second display area AA2.

[0108] The orthographic projection of the light-transmitting opening 24 on the substrate 1 is a first projection, and the orthographic projection may be a projection obtained along the thickness direction Z of the display panel. Multiple first projections may be arranged in an array on the substrate 1. In some embodiments, when there is no other first projection in the direction of any first projection close to the boundary of the first display area that is closest to it, the first projection is considered to be located at the boundary of the first display area. In other embodiments, the first projections are arranged in an array along the first direction and the second direction, and when there is no first projection distributed in the adjacent columns (rows) on one side of any first projection along the first direction or the second direction, the first projection is considered to be located at the boundary of the first display area. The connecting lines of multiple first projections located at the boundary of the first display area enclose a virtual polygon P, and the virtual polygon P may be adapted to a light-sensing element with an irregular shape, so that the size of the first display area AA1 is smaller on the basis of having enough light passing through the first display area AA1. The side L of the virtual polygon P may extend along the edge of the first projection, so that the virtual polygon P may surround all the first projections. The virtual polygon P may be a regular polygon or an irregular figure. For example, a regular polygon may be a regular pentagon, a regular hexagon, a regular heptagon, etc., and an irregular figure may be a figure with irregular protrusions.

[0109] The display panel provided in the present application may also include a touch layer 4 disposed on the side of the isolation structure 2 facing away from the substrate 1, a cover plate 6 located on the side of the touch layer 4 facing away from the substrate 1, an optical adhesive layer 5 located between the cover plate 6 and the touch layer 4, etc. The touch layer 4 enables the display device to perform touch operation. The touch layer 4 can be disposed on the light-emitting side of the light-emitting functional layer 3. In order to prevent the touch layer 4 from affecting the display of the light-emitting functional layer 3, the touch layer 4 can be prepared using a light-transmitting conductive material, such as indium oxide-tin oxide (ITO), indium oxide-zinc oxide (IZO), etc. The light emitted by the light-emitting portion 31 can pass through the touch layer 4, the optical adhesive layer 5, the cover plate 6, etc., and the light incident on the display panel can pass through the touch layer 4, the optical adhesive layer 5, the cover plate 6, etc.

[0110] In the embodiment provided in the present application, by setting a light-transmitting opening 24 in the first display area AA1, the light transmittance of the first display area AA1 can be improved, so that one side of the first display area AA1 is suitable for placing a light-sensing element; by setting a light-emitting portion 31 in a limited opening 23 opened on the isolation structure 2, the isolation structure 2 can be used to divide the light-emitting portions 31 in the display panel; by setting a plurality of first projections located at the boundary of the first display area to enclose a virtual polygon P to form, the virtual polygon P includes n side edges L, n>4, so as to reduce the display difference between the first display area AA1 and the second display area AA2, and the outline of the virtual polygon P can adapt to the light-sensing element with an irregular shape to balance the amount of light transmitted from the first display area AA1 and the size of the first display area AA1.

[0111] In some embodiments, at least a portion of the virtual polygon P has different sizes along the first direction X, or at least a portion of the virtual polygon P has different sizes along the second direction.

[0112] The first direction X and the second direction Y may be the length direction or the width direction of the display panel, respectively. At least part of the virtual polygon P has different sizes along the first direction X, or at least part of the virtual polygon P has different sizes along the second direction Y, so that the virtual polygon P has inclined sides relative to the first direction X or the second direction Y to adapt to light sensing components with different regular shapes.

[0113] In some embodiments, the size of the virtual polygon P along the first direction X is H, and the size H of at least a portion of the virtual polygon gradually decreases or increases along the second direction Y.

[0114] The dimension H gradually decreases or increases along the second direction Y, that is, one or more side edges corresponding to the dimension H are arranged non-parallel to the second direction Y to adapt to the shape of the light sensing component that does not extend along the second direction Y.

[0115] In some embodiments, the size of the virtual polygon P gradually decreases or increases along the second direction Y by the size of at least one sub-pixel. Along the second direction Y, the partial size H remains unchanged, and the minimum amplitude of the increase or decrease of the partial size H is the size of a sub-pixel, thereby preventing the opening of the light-transmitting opening 24 from affecting the distribution of the light-emitting portion 31.

[0116] In some embodiments, the size of the virtual polygon P along the second direction Y is W, and the size W of at least a portion of the virtual polygon P gradually decreases or increases along the first direction X.

[0117] The dimension W gradually decreases or increases along the first direction X, that is, one or more side edges corresponding to the dimension W are arranged non-parallel to the first direction X to adapt to the shape of the light sensing element that does not extend along the first direction X.

[0118] In some embodiments, the size of the virtual polygon P gradually decreases or increases along the first direction X by the size of at least one sub-pixel. Along the first direction X, the size W of a part remains unchanged, and the minimum amplitude of the increase or decrease of the size W of a part is the size of a sub-pixel, thereby avoiding the distribution of the light-emitting portion 31 being affected by the opening of the light-transmitting opening 24 .

[0119] In some embodiments, the plurality of light emitting portions 31 are spaced apart along the first direction X and the second direction Y, and the first direction X and the second direction Y intersect.

[0120] The light-transmitting openings 24 may be distributed between the light-emitting portions 31 adjacent to each other along the first direction X, or may be distributed between the light-emitting portions 31 adjacent to each other along the second direction Y. The light-emitting portions 31 are spaced apart along the first direction X and the second direction Y, and at least a portion of the virtual polygon P has different sizes along the first direction X, or at least a portion of the virtual polygon P has different sizes along the second direction, so that the virtual polygon P can adapt to the shape of the light sensor that does not extend along the first direction X or the second direction Y.

[0121] See also Figure 4 In some embodiments, the plurality of light-transmitting openings 24 include a first opening 241, the first opening 241 is located between adjacent limiting openings 23 in the first direction X, the n side edges L include a first side edge L1 and a second side edge L2, the first side edge L1 extends along the first direction X, the first side edge L1 is a line connecting at least two first projections of the first openings 214 arranged along the first direction X, the second side edge L2 extends along the second direction Y, the second side edge L2 is a line connecting at least two first projections arranged along the second direction Y, and the first direction X and the second direction Y intersect.

[0122] In the case where the display panel only includes the first opening 241, the virtual polygon P only includes the first side L1 extending along the first direction X and the second side L2 extending along the second direction Y, and the first side L1 and the second side L2 are alternately connected. By changing the length of the first side L1 and the length of the second side L2, a light sensing element with an irregular shape can be adapted.

[0123] In some embodiments, a length of the first opening 241 along the first direction X is less than a length of the first opening 214 along the second direction Y.

[0124] The first opening 241 may be in a rectangular, elliptical, etc. The length of the first opening 241 along the first direction X is set to be smaller than the length of the first opening 241 along the second direction Y, thereby reducing the spacing distance between adjacent light emitting portions 31 along the first direction X and ensuring that the first opening 241 has a suitable opening area.

[0125] In some embodiments, when the first projection is a polygon, the connecting line of the plurality of first projections is the connecting line of the outer edges of the plurality of first projections. In other embodiments, when the first projection has an arcuate edge, the connecting line of the plurality of first projections is the connecting line of the outer tangent lines of the arcuate edges of the plurality of first projections. Those skilled in the art can select a suitable method to form the connecting line connecting the first projections as needed, so that the virtual polygon P can surround all the first projections.

[0126] In some embodiments, the first display area AA1 includes a third boundary A3, which extends along a third direction R, and the first direction X, the second direction Y and the third direction R intersect each other; a plurality of alternately connected first side edges L1 and second side edges L2 form a tooth structure, and the connection points O of the first side edges L1 and the second side edges L2 in the tooth structure are arranged along the third boundary.

[0127] The boundary of the first display area AA1 can completely overlap with the projection of the light sensor on the display panel, or be a coaxially arranged figure. The first display area AA1 has a third boundary A3 extending along the third direction R, that is, the first display area AA1 has a third boundary A3 that does not extend along the first direction X or the second direction Y. In this embodiment, a tooth structure is formed by a plurality of alternately connected first side edges L1 and second side edges L2, and the connection points of the first side edges L1 and the second side edges L2 in the tooth structure are arranged along the third boundary A3, so that the virtual polygon P can extend along the third boundary A3 on a macro level, and more first openings 241 can be set in the first display area AA1 on a micro level.

[0128] In some embodiments, the first display area AA1 includes a first boundary A1 extending along the first direction X, and the n side edges L include a third side edge L3 extending along the first boundary A1.

[0129] In some embodiments, the first display area AA1 includes a second boundary A2 extending along the second direction Y, and the n side edges L include a fourth side edge L4 extending along the second boundary A2.

[0130] The first display area AA1 may not only include the third boundary A3, but also may set the first boundary A1 and the second boundary A2 as needed. For the first boundary A1 and the second boundary A2, it is only necessary to set a plurality of first openings 241 arranged along the first direction X to form a third side L3 as a line; and set a plurality of first openings 241 arranged along the second direction Y to form a fourth side L4 as a line.

[0131] See also Figure 5 and Figure 6In some embodiments, the plurality of light-transmitting openings 24 include a first opening 241 and a second opening 242 , wherein the first opening 241 is located between adjacent defined openings in the first direction X, and the second opening 242 is located between adjacent defined openings 23 in the second direction Y.

[0132] The plurality of limiting openings 23 are distributed at intervals in the first direction X and the second direction Y. By regularly setting the arrangement positions of the light-transmitting openings 24 , the display uniformity of the display panel can be improved.

[0133] The light-transmitting openings 24 are disposed not only between the adjacent limiting openings 23 along the first direction X, but also between the limiting openings 23 along the second direction Y, thereby increasing the distribution density of the limiting openings 23 per unit area in the first display area AA1 and improving the light transmittance of the first display area AA1.

[0134] In some embodiments, the length of the second opening 242 along the first direction X is greater than the length of the first opening 241 along the second direction Y.

[0135] The first opening 241 may be a rectangle with a length direction in the second direction Y, and the second opening 242 may be a rectangle with a length direction in the first direction X, so as to reduce the spacing between adjacent defined openings 23 along the first direction X and the second direction Y.

[0136] In some embodiments, the n sides include a fifth side L5 , the extension direction of the fifth side L5 is different from the first direction X and the second direction Y, and the fifth side L5 is a line connecting a first projection of at least one first opening 241 and a first projection of at least one second opening 242 .

[0137] The fifth side L5 may be a line connecting the vertex angles of the first projection of at least one first opening 241 and the first projection of at least one second opening 242. That is, the fifth side L5 may not be arranged along the outer edge extending along the first direction X or the outer edge extending along the second direction Y in the first projection. By changing the number of rows or columns of the light emitting portions 31 spaced between the first opening 241 and the second opening 242 forming the fifth side L5, the fifth side L5 may be adjusted to have different slopes relative to the first direction X.

[0138] In some embodiments, the light transmittance of the first display area AA1 is greater than the light transmittance of the second display area AA2.

[0139] When the pixel arrangement density of the light-emitting portion 31 located in the first display area AA1 is the same as the pixel arrangement density of the light-emitting portion 31 located in the second display area AA2, and the area of ​​the orthographic projection of the light-emitting portion 31 located in the first display area AA1 on the substrate 1 is the same as the area of ​​the orthographic projection of the light-emitting portion 31 located in the second display area AA2 on the substrate 1, by setting a light-transmitting opening 24 in the first display area AA1, the light transmittance of the first display area AA1 can be improved, so that the light transmittance of the first display area AA1 is greater than that of the second display area AA2.

[0140] In some embodiments, the pixel arrangement density of the light-emitting portion 31 located in the first display area AA1 is smaller than the pixel arrangement density of the light-emitting portion 31 located in the second display area AA2, and the area of ​​the orthographic projection of the light-emitting portion 31 located in the first display area AA1 on the substrate 1 is the same as the area of ​​the orthographic projection of the light-emitting portion 31 located in the second display area AA2 on the substrate 1.

[0141] Since the light-transmitting opening 24 can be omitted in the second display area AA2, more defined openings 23 can be divided into a unit area in the second display area AA2, thereby increasing the pixel arrangement density of the light-emitting portion 31 in the second display area AA2 and improving the light-emitting brightness of the second display area AA2.

[0142] In some embodiments, the pixel arrangement density of the light-emitting portion 31 located in the first display area AA1 is the same as the pixel arrangement density of the light-emitting portion 31 located in the second display area AA2, and the area of ​​the orthographic projection of the light-emitting portion 31 located in the first display area AA1 on the substrate 1 is smaller than the area of ​​the orthographic projection of the light-emitting portion 31 located in the second display area AA2 on the substrate 1.

[0143] Since the light-transmitting opening 24 can be omitted in the second display area AA2, a larger defined opening 23 can be divided per unit area in the second display area AA2, thereby increasing the density of the light-emitting parts 31 in the second display area AA2 and improving the light-emitting brightness of the second display area AA2.

[0144] Since there is a certain difference between the pixel arrangement density of the light-emitting portion 31 distributed in the first display area AA1 and the pixel arrangement density of the light-emitting portion 31 distributed in the second display area AA2, or there is a certain difference between the orthographic projection area of ​​the light-emitting portion 31 distributed in the first display area AA1 and the orthographic projection area of ​​the light-emitting portion 31 distributed in the second display area AA2, there is a certain difference in the display effects of the first display area AA1 and the second display area AA2. A virtual polygon P with a side L greater than 4 is formed by connecting the first projections located at the edges of multiple first projections. The side L of the virtual polygon P has a more complex direction than the side L of a triangle or a quadrilateral, thereby increasing the difficulty of distinguishing the boundary between the first display area AA1 and the second display area AA2, so that the display panel can have better optical image quality and display uniformity. When the area of ​​the orthographic projection of the light-emitting portion 31 located in the first display area AA1 on the substrate 1 is smaller than the area of ​​the orthographic projection of the light-emitting portion 31 located in the second display area AA2 on the substrate 1, the service life of the light-emitting portion 31 located in the first display area AA1 will be lower than that of the light-emitting portion 31 located in the second display area AA2, so that after the display panel has been used for a period of time, the luminous brightness of the first display area AA1 may be weaker than that of the light-emitting portion 31 located in the second display area AA2. By forming a virtual polygon P with a side L greater than 4 by connecting the first projections located at the edges of multiple first projections, the difficulty of distinguishing the boundary between the first display area AA1 and the second display area AA2 is increased, thereby improving the display effect of the display panel.

[0145] In some embodiments, the plurality of light-emitting portions 31 include a first light-emitting portion 311, the first light-emitting portion 311 is used to emit a first color light, the plurality of first light-emitting portions 311 are arranged at intervals along a first direction X to form a first light-emitting group 31a, the plurality of first light-emitting groups 31a are arranged at intervals along a second direction Y, and at least part of the first projection is located between the orthographic projections of the first light-emitting portions 311 adjacent to each other along the first direction X on the substrate 1.

[0146] The first direction X and the second direction Y may be perpendicular to each other. When the display panel is rectangular, the first direction X and the second direction Y may be the length direction and the width direction of the display panel, respectively. The first color light may be any color light such as red light, blue light, green light, etc. At least part of the first projection is located between the orthographic projections of the first light-emitting portions 311 adjacent to each other along the first direction X on the substrate 1, so that light can pass through the light-transmitting opening 24 between the adjacent first light-emitting portions 311.

[0147] In some embodiments, the plurality of light-emitting portions 31 include a second light-emitting portion 312, which is used to emit a second color light. The plurality of second light-emitting portions 312 are arranged in intervals along the first direction X to form a second light-emitting group 31b. The second light-emitting group 31b is disposed between two adjacent first light-emitting groups 31a, and at least part of the first projection is located between the orthographic projections of the second light-emitting portions 312 adjacent to each other along the first direction X on the substrate 1.

[0148] The wavelength of the second color light is different from that of the first color light. The light emitting parts 31 in the first light emitting group 31a all emit the first color light, and the light emitting parts 31 in the second light emitting group 31b all emit the second color light. At least part of the first projection is located between the orthographic projections of the second light emitting parts 312 adjacent to each other along the first direction X on the substrate 1, so that light can pass through the light-transmitting opening 24 between the adjacent first light emitting parts 311.

[0149] Since the light-transmitting opening 24 is disposed between adjacent first light-emitting portions 311 or between adjacent second light-emitting portions 312, the light-transmitting opening 24 between the first light-emitting portions 311 and the light-transmitting opening 24 between the second light-emitting portions 312 can be disposed at intervals along the second direction Y, so that each side L of the virtual polygon P extends along the first direction X or the second direction Y. The side L extending along the first direction X and the side L extending along the second direction Y are connected to form a right-angle structure, and multiple right-angle structures are repeatedly connected to form a sawtooth structure. By controlling the number and position of the repeatedly connected right-angle structures, a sawtooth structure adapted to the arc-shaped outer edge of the light-sensing element can be obtained.

[0150] In some embodiments, at least a portion of the first projection is located between orthographic projections of the first light emitting portion 311 and the second light emitting portion 312 adjacent to each other along the second direction Y on the substrate 1 .

[0151] A light-transmitting opening 24 is disposed between the adjacent first light-emitting portions 311 and the second light-emitting portions 312 , so that light can pass through the adjacent first light-emitting portions 311 and the second light-emitting portions 312 , thereby improving light transmittance of the first display area AA1 .

[0152] In some embodiments, the plurality of light-emitting portions 31 include a third light-emitting portion 313, which is used to emit a third color light. The plurality of third light-emitting portions 313 are arranged at intervals along the first direction X to form a third light-emitting group 31c. The first light-emitting group 31a, the second light-emitting group 31b and the third light-emitting group 31c are arranged in sequence along the second direction Y, and at least part of the first projection is located between the orthographic projections of the third light-emitting portions 313 adjacent to each other along the first direction X on the substrate 1.

[0153] The first color light, the second color light and the third color light are lights of different wavelengths. Optionally, the first color light, the second color light and the third color light are red light, blue light and green light respectively. At least part of the first projection is located between the orthographic projections of the third light emitting portions 313 adjacent to each other along the first direction X on the substrate 1, so that light can pass through the light-transmitting opening 24 between the adjacent third light emitting portions 313.

[0154] In some embodiments, at least a portion of the first projection is located between the orthographic projections of the second light emitting portion 312 and the third light emitting portion 313 adjacent to each other along the second direction Y on the substrate 1 .

[0155] In some other embodiments, at least part of the first projection is located between the orthographic projections of the third light emitting portion 313 and the first light emitting portion 311 adjacent to each other along the second direction Y on the substrate 1 .

[0156] A light-transmitting opening 24 is provided between the adjacent first light-emitting portion 311 and the third light-emitting portion 313 and between the adjacent second light-emitting portion 312 and the third light-emitting portion 313 to improve the light transmittance of the first display area AA1.

The fourth light-emitting group 31d and the fifth light-emitting group 31e are alternately arranged along the second direction Y, and at least part of the first projection is located between the orthographic projections of the first light-emitting portion 311 and the third light-emitting portion 313 adjacent to each other along the second direction Y on the substrate 1, and at least part of the first projection is located between the orthographic projections of the second light-emitting portion 312 and the third light-emitting portion 313 adjacent to each other along the second direction Y on the substrate 1.

[0159] The first light emitting portion 311 and the second light emitting portion 312 are alternately arranged along the first direction X, and the third light emitting portion 313 is arranged along the first direction X, so that the proportion of the third light emitting portion 313 per unit area can be increased. Optionally, the third light emitting portion 313 is a blue light emitting portion 313, and the first light emitting portion 311 and the second light emitting portion 312 are a red light emitting portion 311 and a green light emitting portion 312.

[0161] In some embodiments, the plurality of first projections are orthographic projections of the light emitting portion 31 on the substrate 1 .

[0162] The first projections are formed around the orthographic projection of the light emitting portion 31 on the substrate 1 to increase the number of light-transmitting openings 24 per unit area and improve the light transmittance of the first display area AA1 , so that the light emitting portion 31 is evenly transparent around.

Along the direction from the isolation structure 2 to the substrate 1 (Z direction), the second portion 22 completely blocks the first portion 21.

[0171] When preparing the light-emitting portion 31, the light-emitting material used to prepare the light-emitting portion 31 can be covered on the isolation structure 2 based on the evaporation technology. Since the second part 22 blocks the first part 21, the light-emitting material used to prepare the light-emitting portion 31 has a large drop at the edge of the second part 22, and the light-emitting material falling in the defined opening 23 and the light-emitting material falling on the second part 22 are difficult to connect, so that they are broken, forming light-emitting materials arranged in adjacent defined openings 23 at intervals. The light-emitting material falling on the second part 22 can be removed as needed. Compared with the preparation of the light-emitting functional layer 3 by mask evaporation in the related art, the present application sets the first part 21 and the second part 22, so that the light-emitting portion 31 located in the defined opening 23 can be prepared without a metal mask, thereby saving the cost of preparing a metal mask. Compared with preparing the light-emitting functional layer 3 by preparing a high-precision metal mask evaporation, it is easier to directly prepare a high-precision isolation structure 2, so that the structure of the display panel provided by the present application has low requirements on the preparation process, and the consistency of the prepared display panel is good. The light-emitting material can be a complex containing indium element.

[0172] In some embodiments, the orthographic projection area of ​​the surface of the second portion 22 facing away from the substrate 1 on the substrate 1 is smaller than the orthographic projection area of ​​the surface of the second portion 22 close to the substrate 1 on the substrate 1 .

[0173] The second portion 22 extends outwardly by a predetermined distance relative to the first portion 21, that is, the orthographic projection area of ​​the surface of the second portion 22 facing away from the substrate 1 on the substrate 1 is smaller than the orthographic projection area of ​​the surface of the second portion 22 close to the substrate 1 on the substrate 1, so that the second portion 22 has an inclined slope structure, so that the pattern of the light-emitting functional layer 3 can be defined by the second portion 22.

[0174] In some embodiments, the cross-sectional area of ​​the second portion 22 gradually decreases in a direction away from the substrate 1 .

[0175] Optionally, the cross-section of the second portion 22 is a trapezoid with the bottom edge facing the substrate 1, so that the second portion 22 has a sloped surface, which is conducive to the preparation material being disconnected at the partition edge, forming a state in which part of the preparation material is located on the second portion 22 and part of the preparation material is located in the limited opening 23.

[0176] In some embodiments, the orthographic projection area of ​​the surface of the first portion 21 facing away from the substrate 1 on the substrate 1 is smaller than the orthographic projection area of ​​the surface of the second portion 22 close to the substrate 1 on the substrate 1 .

[0177] That is, the second portion 22 extends outward relative to the first portion 21, so as to limit the pattern of the first electrode 32 and the light-emitting functional layer 3 through the second portion 22. The area of ​​the second portion 22 is larger than that of the first portion 21, and the first portion 21 is completely covered, and at this time, the first portion 21 is recessed relative to the second portion 22 in a direction away from the defined opening 23. When preparing the second electrode 33, the second electrode 33 has a large drop at the edge of the isolation structure 2, and the first portion 21 is recessed, so that the second electrode 33 is difficult to connect outside the isolation structure 2, and thus a break is found, forming mutually isolated second electrodes 33.

[0178] In some embodiments, the orthographic projection area of ​​the surface of the second portion 22 facing away from the substrate 1 on the substrate 1 is smaller than the orthographic projection area of ​​the surface of the second portion 22 close to the substrate 1 on the substrate 1 .

[0179] In some embodiments, the cross-sectional area of ​​the first portion 21 gradually decreases in a direction away from the substrate 1 .

[0180] The cross section of the first part 21 may be a trapezoid, which increases the size of the defined opening 23. The cross section of the first part 21 may be a regular trapezoid, which can stably support the second part 22 on the one hand, and on the other hand, makes the contact surface area between the first part 21 and the second part 22 smaller, so that the first part 21 is concavely arranged relative to the second part 22 in a direction away from the central axis of the defined opening 23, so that the light-emitting functional layer 3 is disconnected at the isolation structure 2.

[0181] In these optional embodiments, in order to obtain the first portion 21 with a concave setting, during the etching process, a part of the first portion 21 has a faster etching rate than the second portion 22, thereby forming the concave first portion 21. Since the etching rate of the first portion 21 is faster, more waste generated by etching is easy to enter other positions of the display panel, thereby causing adverse effects. The orthographic projection of the first portion 21 on the substrate 1 is set to be within the orthographic projection of the first portion 21 on the substrate 1, so that the first portion 21 can be better supported on the first portion 21, and the generated etching waste falls on the first portion 21, which is easy to clean.

[0182] In some embodiments, the display panel further includes a pixel definition layer 7 disposed between the substrate 1 and the isolation structure 2 , the pixel definition layer 7 includes a pixel opening, and the orthographic projection of the pixel opening on the substrate 1 is located within the orthographic projection range of the limiting opening 23 on the substrate 1 .

[0183] The pixel definition layer 7 includes a pixel defining portion, which encloses a pixel opening. At least a portion of the light emitting portion 31 can be disposed in the pixel opening to achieve light emitting display of the display panel. The pixel opening can be disposed corresponding to the defining opening 23 .

[0184] In some embodiments, the isolation structure 2 is disposed on a side of the pixel definition layer 7 facing away from the substrate 1 , and the light-emitting functional layer 3 is at least partially disposed in the pixel opening.

[0185] The isolation structure 2 is arranged on the side of the pixel definition layer 7 facing away from the substrate 1, and the orthographic projection of the pixel opening on the substrate 1 is located within the orthographic projection of the limiting opening 23 on the substrate 1. The isolation structure 2 can be directly arranged on the side of the pixel definition layer 7 facing away from the substrate 1, and the isolation structure 2 is supported by the pixel definition layer 7. The orthographic projection of the pixel opening on the substrate 1 can be located within the orthographic projection of the limiting opening 23 on the substrate 1. The area of ​​the limiting opening 23 is larger than the area of ​​the pixel opening, which can reduce the influence of the isolation structure 2 on the light output viewing angle of the light-emitting functional layer 3.

[0186] Optionally, there are multiple pixel openings, which are spaced apart, and the isolation structure 2 can be disposed on at least part of the pixel defining portion between two adjacent pixel openings. Optionally, the isolation structure 2 can be disposed around at least part of the pixel openings.

[0187] In some embodiments, the pixel definition layer 7 is exposed from the light-transmitting opening 24 .

[0188] In some embodiments, the display panel further includes a planar layer 8 , which is disposed in the light-transmitting opening 24 . The planar layer 8 is also used to planarize a side of the isolation structure 2 that is away from the substrate 1 .

[0189] An embodiment of the second aspect of the present application further provides a display panel, which includes a substrate 1, an isolation structure 2 and a light-emitting functional layer 3, wherein the isolation structure 2 is arranged on one side of the substrate 1, and the isolation structure 2 encloses a plurality of defined openings 23 and a plurality of light-transmitting openings 24; the light-emitting functional layer 3 includes a plurality of light-emitting portions 31, and the light-emitting portions 31 are at least partially arranged in the defined openings 23; wherein the projection of the light-transmitting openings 24 on the substrate 1 and the projection of the defined openings 23 on the substrate 1 do not overlap, the light-transmitting openings 24 are arranged at intervals along the row direction Y and the column direction X, and at least some of the light-transmitting openings 24 in two adjacent rows have different extension distances in the column direction X, or at least some of the light-transmitting openings in two adjacent columns have different extension distances in the row direction Y.

[0190] The row direction Y and the column direction X may be the first direction and the second direction in the aforementioned embodiment. The total length of the plurality of light-transmitting openings 24 arranged along the row direction Y is the distance that the row of light-transmitting openings 24 extends in the row direction Y. The total length of the plurality of light-transmitting openings 24 arranged along the column direction X is the distance that the column of light-transmitting openings 24 extends in the row direction Y.

[0191] In the embodiments provided in the present application, at least some of the light-transmitting openings 24 in two adjacent rows extend at different distances in the column direction X, or at least some of the light-transmitting openings in two adjacent columns extend at different distances in the row direction Y, thereby reducing the display difference between the area where the light-transmitting openings 24 are provided and the area where the light-transmitting openings 24 are not provided. The extension distances of the light-transmitting openings 24 in the row direction Y and the column direction X can be adapted to light-sensing elements with irregular shapes to balance the amount of light transmitted through the area where the light-transmitting openings 24 are provided and the proportion of the area where the light-transmitting openings 24 are provided to the entire display panel.

[0192] In some embodiments, the light-transmitting openings 24 are arranged into M columns along the row direction Y, and the light-transmitting openings are arranged into N rows along the column direction X. The display panel includes a first frame 71 and a second frame 72 oppositely arranged along the row direction Y. The light-transmitting openings in the n1th row are close to the light-transmitting openings of the first frame 71 and are located in the m1th column. The light-transmitting openings in the n1+1th row are close to the light-transmitting openings of the first frame 71 and are located in the m1+ith column. N and M are positive integers, i is a non-zero integer, n1∈N, (n1+1)∈N, m1∈M, (m1+i)∈M.

[0193] For example: Fig.10 As shown, M is 10, N is 10. n1 is 1, m1 is 5, that is, the light-transmitting openings in the first row of light-transmitting openings close to the first frame 71 are located in the fifth column. n1+1 is 2, i is -2, m1+i is 2, that is, the light-transmitting openings in the second row of light-transmitting openings close to the first frame 71 are located in the third column.

[0194] In the display panel, the light-transmitting openings 24 close to the first frame 71 in at least two rows of light-transmitting openings are located in different columns, so that the distribution of the light-transmitting openings 24 can adapt to the irregular shape of the light sensing element.

[0195] In some embodiments, the display panel includes a third frame 73 and a fourth frame 74 arranged opposite to each other along the column direction X, the light-transmitting opening of the m2th column is close to the light-transmitting opening of the third frame 73 located in the n2th row, the light-transmitting opening of the n2+1th row is close to the light-transmitting opening of the first frame 71 located in the m2+jth column, j is a non-zero integer, n2∈N, (n2+1)∈N, m2∈M, (m2+j)∈M.

[0196] For example: Fig.10 As shown, M is 10, N is 10. n2 is 3, m2 is 1, that is, the light-transmitting openings in the first column close to the third frame 73 are located in the third row. m2+1 is 2, j is -1, m2+i is 2, that is, the light-transmitting openings in the second column close to the third frame 73 are located in the second column.

[0197] In the display panel, the light-transmitting openings 24 close to the third frame 73 in at least two columns of light-transmitting openings 24 are located in different columns, so that the distribution of the light-transmitting openings 24 can adapt to the irregular shape of the light sensing element.

[0199] The column direction X may be the first direction in the above-mentioned embodiment. The total length of the plurality of first openings 241 arranged along the column direction X is the distance that the first openings 241 in the column extend in the column direction X.

[0200] In the embodiments provided in the present application, at least some of the first openings 241 in two adjacent columns have different extension distances in the column direction X, thereby reducing the display difference between the area where the first openings 241 are provided and the area where the first openings 241 are not provided. The extension distance of the first openings 241 in the column direction X can be adapted to the light sensing element with an irregular shape to balance the amount of light transmitted through the area where the first openings 241 are provided and the proportion of the area where the first openings 241 are provided to the entire display panel.

[0201] In some embodiments, the numbers of the first openings 241 in at least two adjacent columns distributed in the column direction X are different.

[0202] In two adjacent columns of first openings 241, the extension lengths of the first openings 241 along the column direction X can be consistent, and the interval lengths of adjacent first openings 241 along the column direction X can be consistent. By changing the number of the multiple first openings 241 distributed in the column direction X of at least part of the two adjacent columns, the extension lengths of the multiple first openings 241 in the column direction X of the two adjacent columns are different.

[0207] In some embodiments, the light-transmitting openings are arranged into M columns along the row direction Y, and the light-transmitting openings are arranged into N rows along the column direction X. The first opening 241 of the n1th row extends to the m1th column along the row direction Y, and the light-transmitting openings of the n1+1th row extend to the m1+ith column along the row direction Y. N and M are positive integers, i is a non-zero integer, n1∈N, (n1+1)∈N, m1∈M, and (m1+i)∈M.

[0209] In some embodiments, the light-transmitting openings further include a plurality of second openings 242 spaced apart along the row direction Y, and the extension distances of the plurality of second openings 242 in at least two adjacent rows in the row direction Y are different.

[0210] The row direction Y may be the second direction in the above-mentioned embodiment. The total length of the plurality of second openings 242 arranged along the row direction Y is the distance that the row of second openings 242 extends in the row direction Y.

[0211] By providing the first opening 241 and the second opening 242 , the light transmission area of ​​the display panel is increased.

[0212] In some embodiments, the numbers of the second openings 242 in at least two adjacent rows distributed in the row direction Y are different.

[0213] In two adjacent rows of second openings 242, the extension lengths of the second openings 242 along the row direction Y can be consistent, and the spacing lengths of adjacent second openings 242 along the row direction Y can be consistent. By changing the number of the multiple second openings 242 distributed in the row direction Y of at least part of the two adjacent rows, the extension lengths of the multiple second openings 242 in the row direction Y of two adjacent columns are different.

[0214] In some embodiments, the spacing distances between the second openings 242 in at least two adjacent rows are different in the row direction Y.

By changing the spacing lengths of at least some of the adjacent second openings 242 along the row direction Y, the extension lengths of the multiple second openings 242 in the row direction Y in two adjacent columns are different.

[0216] In some embodiments, among at least some of the second openings 242 in two adjacent rows, the lengths of the second openings 242 in different rows along the row direction Y are different.

[0217] In two adjacent rows of second openings 242, the spacing lengths of adjacent second openings 242 along the row direction Y can be consistent, and the number of multiple second openings 242 distributed in the row direction Y in two adjacent rows can be consistent. By changing the extension length of at least part of the second openings 242 along the row direction Y, the extension lengths of multiple second openings 242 in the row direction Y in two adjacent columns are different.

N and M are positive integers, i is a non-zero integer, n1∈N, (n1+1)∈N, m1∈M, and (m1+i)∈M.

[0219] For example: Fig.10 As shown, M is 10, N is 10. n2 is 1, m2 is 1, that is, the second opening 242 of the first column extends to the tenth row along the row direction Y; n1+1 is 2, i is -1, m1+i is 9, that is, the second opening 242 of the second column extends to the ninth row along the column direction X.

[0220] The embodiment of the fourth aspect of the present application also provides a display device, including the display panel of any of the first, second, and third aspects. Since the display device provided by the embodiment of the fourth aspect of the present application includes the display panel of any of the first, second, and third aspects, the display device provided by the embodiment of the fourth aspect of the present application has the beneficial effects of the display panel of any of the fourth aspects, which will not be described in detail here.

[0221] The display device in the embodiments of the present application includes but is not limited to mobile phones, personal digital assistants (PDAs), tablet computers, e-books, televisions, access control systems, smart landline phones, consoles, and other devices with display functions.

[0222] In some embodiments, the display device includes a light sensor, which is disposed on one side of the display panel. The orthographic projection of the light sensor on the display panel at least partially overlaps with the first display area AA1.

[0223] The light sensor may be a photoelectric sensing device such as a camera, an infrared rangefinder, etc. The orthographic projection of the light sensor on the display panel at least partially overlaps with the first display area AA1, so that light passing through the first display area AA1 can enter the light sensor.

[0224] In some embodiments, the orthographic projection of the light sensor on the display panel falls within the first display area AA1 , so as to increase the proportion of light passing through the first display area AA1 entering the light sensor.

[0225] In some embodiments, the orthographic projection of the light sensor on the substrate 1 and the virtual polygon P are similar shapes.

[0226] When the orthographic projection of the light sensor on the substrate 1 is a special-shaped figure, the virtual polygon P is the same or a proportionally enlarged special-shaped figure. The orthographic projection of the light sensor on the substrate 1 and the virtual polygon P are similar figures, thereby balancing the amount of light incident on the light sensor from the first display area AA1 and the size of the first display area AA1.

[0227] In some embodiments, the orthographic projection of the light emitting portion 31 on the substrate 1 is the second projection, and the number of the second projections located between the orthographic projection of the light sensor on the substrate 1 and the virtual polygon P along the first direction X is 5 to 20; the number of the second projections located between the orthographic projection of the light sensor on the substrate 1 and the virtual polygon P along the second direction Y is 5 to 20, so as to ensure that all light rays transmitted through the first display area AA1 can enter the light sensor.

[0228] According to the embodiments of the present application as above, these embodiments do not describe all the details in detail, nor do they limit the invention to specific embodiments. Obviously, many modifications and changes can be made based on the above description. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present application, so that those skilled in the art can make good use of the present application and the modifications based on the present application.
