[0110] In related technologies, in order to improve the fabrication accuracy of the light-emitting unit of the display panel, an isolation structure is usually used as an auxiliary structure in the fabrication process of the light-emitting unit. However, the isolation structure will affect the light-emitting range of the light-emitting unit. Especially in touch display panels, under the combined influence of the isolation structure and the touch layer, the light-emitting range of the light-emitting unit in different directions will be different, which will cause color shift in the display image.

[0111] Patents PCT / CN2023 / 134518, 202310771071.0, 202311117143.6, 202310759370.2, 202410008807.3, 202310909421.5, and 202311616249.0 describe related technical solutions for isolation structures, pixel arrangements, touch control, and arrays, the contents of which are incorporated herein by reference. Therefore, to solve the above problems, in a first aspect, embodiments of the present invention propose a display panel and a display device.

[0112] Figure 1 This is a top view of a display panel provided in an embodiment of this application. Figure 2 yes Figure 1 A schematic diagram of an enlarged structure of Q. Figure 3 This is a cross-sectional structural diagram of a display panel provided in an embodiment of this application.

[0113] like Figures 1 to 3 As shown, this application embodiment provides a display panel, which includes an array substrate 10, a light-emitting layer, an isolation structure 20, and a touch layer 40. The light-emitting layer is located on one side of the array substrate 10 and includes a plurality of light-emitting units 30. The plurality of light-emitting units 30 includes a plurality of light-emitting unit groups E0. Each light-emitting unit group E0 emits a single color of light, and the light-emitting unit group E0 includes at least one light-emitting structure disposed along a first direction X. The isolation structure 20 is located on one side of the array substrate 10 and includes an isolation opening 21. The light-emitting units 30 are disposed in the isolation opening 21. The touch layer 40 includes touch traces 41. The touch traces 41 are disposed on the side of the isolation structure 20 facing away from the array substrate 10. At least a portion of the orthographic projection of the touch traces 41 in the thickness direction Z of the display panel is disposed around at least one light-emitting structure and is symmetrically disposed with respect to a first axis of symmetry N1 passing through the centroid of at least one light-emitting structure. The first axis of symmetry N1 is parallel to the first direction X, and the first direction X intersects the thickness direction Z.

[0114] The array substrate 10 serves as a support, and other film layers are sequentially stacked on it. This stacking refers to the sequential arrangement of the other film layers along the thickness direction Z of the array substrate 10. The array substrate 10 may include multiple film layer structures, and the specific composition of these structures is not limited in this embodiment. Furthermore, the thickness direction Z of other film layers located on one side of the array substrate 10 is generally consistent with the thickness direction Z of the array substrate 10 itself. Therefore, for ease of description, the thickness direction Z of the array substrate 10 or other film layers mentioned later in this embodiment will be shown in the same direction.

[0115] The light-emitting layer and the isolation structure 20 are located on the same side of the array substrate 10. The light-emitting layer includes multiple light-emitting units 30, which are the main devices for realizing light-emitting displays. The light-emitting units 30 include, but are not limited to, red light-emitting units for emitting red light, green light-emitting units for emitting green light, and blue light-emitting units for emitting blue light. Each light-emitting unit 30 may include a stacked hole injection layer (HIL), a hole transport layer (HTL), a light-emitting layer, an electron injection layer (EIL), and an electron transport layer (ETL).

[0116] The light-emitting unit 30 includes several light-emitting unit groups E0. The number of light-emitting structures included in each light-emitting unit group E0 can be the same or different.

[0117] For example, each light-emitting unit group E0 includes a plurality of light-emitting structures arranged sequentially along the first direction X.

[0118] Adjacent light-emitting unit groups E0 can emit light of the same color, or they can emit light of different colors.

[0119] In some examples, the light-emitting structures within multiple light-emitting unit groups E0 can be alternately arranged along a first direction X. For example, multiple light-emitting structures in a red-light-emitting unit group E0 and multiple light-emitting structures in a blue-light-emitting unit group E0 are alternately arranged along the first direction X. In other examples, the multiple light-emitting unit groups E0 are arranged sequentially along a single direction or multiple directions.

[0120] The isolation opening 21 formed by the isolation structure 20 can accommodate the light-emitting unit 30. In other words, the orthographic projection of the light-emitting unit 30 on the array substrate 10 and the orthographic projection of the isolation opening 21 on the array substrate 10 at least partially overlap, and the orthographic projection of the light-emitting unit 30 on the array substrate 10 is at least partially located within the orthographic projection of the isolation opening 21 on the array substrate 10. Furthermore, during the fabrication of the light-emitting unit 30, due to the presence of the isolation structure 20, the light-emitting material can be separated into independent light-emitting units 30 by the isolation structure 20, thus eliminating the need for a precision metal mask evaporation process.

[0121] For example, taking the red light-emitting unit 30 before the green light-emitting unit 30 is fabricated, since the precision metal mask is eliminated, the red light-emitting material corresponding to the red light-emitting unit 30 first falls into each isolation opening 21. Then, a portion of the red light-emitting material in the isolation opening 21 is selectively etched away, while a portion of the red light-emitting material in the isolation opening 21 is retained to form the red light-emitting unit 30. Afterwards, the green light-emitting material corresponding to the green light-emitting unit 30 falls into each isolation opening 21. Then, a portion of the green light-emitting material in the isolation opening 21 is selectively etched away, while a portion of the green light-emitting material in the isolation opening 21 is retained to form the green light-emitting unit 30.

[0122] In this embodiment, the material of the isolation structure 20 includes conductive materials such as metal or alloy, and the through hole 22 is disposed between two adjacent isolation structures 20. The through hole 22 can improve the light transmittance of the display panel to meet the usage requirements of devices that need to be photosensitive.

[0123] Optionally, the orthographic projection shape of the isolation opening 21 along the thickness direction Z includes, but is not limited to, a circle, a square, or a rectangle.

[0124] The touch layer 40 is disposed on the side of the light-emitting layer away from the array substrate 10, and the touch layer 40 can be used to implement touch function. The touch trace 41 is disposed in the display panel, and the touch trace 41 is used to form touch capacitor. After being electrically connected to the driver chip, the touch trace 41 and the driver chip exchange functional signals through the touch capacitor to realize the touch function.

[0125] In some embodiments, at least a portion of the orthogonal projection of the touch trace 41 in the thickness direction Z of the display panel is arranged around at least one light-emitting structure. In other words, the orthogonal projection of the touch trace 41 in the thickness direction Z can be arranged around one or more light-emitting structures.

[0126] For example, when the orthographic projection of the touch trace 41 along the thickness direction Z is arranged around a light-emitting structure, the orthographic projection of the touch trace 41 along the thickness direction Z is distributed around the periphery of the light-emitting structure. The touch trace 41 can be a continuous closed shape or a discontinuous shape. For example, the orthographic projection pattern of the touch trace 41 along the thickness direction Z includes a circular ring or a semi-circular ring.

[0127] For example, when the orthographic projection of the touch trace 41 along the thickness direction Z surrounds multiple light-emitting structures, within the range recognizable by the human eye, the multiple light-emitting structures can be considered as a whole, and the orthographic projection of the touch trace 41 along the thickness direction Z is distributed around the periphery of this whole. Of course, the touch trace 41 can be distributed around the periphery of each light-emitting structure. Optionally, the touch trace 41 between two adjacent light-emitting structures can be one or two.

[0128] The touch traces 41 are symmetrically arranged with respect to a first axis of symmetry N1 passing through the centroid of at least one light-emitting structure. In other words, touch traces 41 are provided on both sides of the first axis of symmetry N1, and since the first axis of symmetry N1 passes through the light-emitting structure, touch traces 41 are provided on both sides of the light-emitting structure symmetrical about the first axis of symmetry N1. Optionally, the centroid includes a geometric center. Optionally, the first axis of symmetry N1 can pass through the geometric center of the light-emitting structure. Optionally, the first axis of symmetry N1 can pass through one light-emitting structure, and of course, it can also pass through multiple light-emitting structures. The touch traces 41 form a grid-like touch pattern, which contains multiple grids, each grid corresponding to at least one light-emitting structure. The portion of the touch pattern surrounding at least one light-emitting structure is symmetrically arranged with respect to at least the first axis of symmetry N1. The term "symmetry" mentioned above and below refers to the touch pattern surrounding at least one light-emitting structure.

[0129] Optionally, in the thickness direction Z, the orthographic projection of the touch trace 41 overlaps with the orthographic projection of the isolation structure 20.

[0130] In the display panel provided in this application, by arranging the touch trace 41 around the isolation opening 21 and symmetrically arranged with respect to the axis of symmetry, the touch trace 41 is arranged on both sides of the light-emitting structure with respect to the axis of symmetry, so that the range of light emitted from opposite sides of the light-emitting structure remains the same, thereby reducing the difference in the range of light emitted by the light-emitting unit 30 in different directions in the isolation opening 21, and further reducing the difference in the brightness of light emitted from different positions of the light-emitting unit 30 at a large viewing angle, thereby reducing the possibility of color shift in the displayed image.

[0131] In some embodiments, please refer to Figures 1 to 3 At least one light-emitting structure includes multiple light-emitting structures, and within the light-emitting unit group E0, the multiple light-emitting structures are arranged sequentially along the first direction X.

[0132] For example, a light-emitting unit group E0 includes multiple light-emitting structures, which are arranged sequentially along a first direction X.

[0133] In some embodiments, please refer to Figures 1 to 3 At least a portion of the orthogonal projection of the touch trace 41 in the thickness direction Z is arranged around a plurality of light-emitting structures and is arranged symmetrically with respect to a first axis of symmetry N1, which passes through the plurality of light-emitting structures.

[0134] In some examples, touch traces are provided around two adjacent light-emitting structures, and a portion of the touch traces surrounding one light-emitting structure surrounds the other light-emitting structure.

[0135] Furthermore, the touch traces 41 are symmetrically arranged with respect to the first axis of symmetry N1, so that touch traces 41 are provided on both sides of the light-emitting structure along the second direction Y. Optionally, the second direction Y and the first direction X are intersecting or perpendicular.

[0136] Optionally, the first axis of symmetry N1 passes through all the light-emitting structures within the light-emitting unit group E0. Of course, the first axis of symmetry N1 passes through a portion of the light-emitting structures within the light-emitting unit group E0.

[0137] In these alternative embodiments, the above-described configuration simplifies the arrangement of the touch traces 41, reduces the viewing angle deviation of the display panel in the second direction Y, and improves the display performance of the display panel.

[0138] In some embodiments, the touch traces 41 form a grid-like touch pattern, the touch pattern comprising multiple grids, each grid corresponding to at least one light-emitting structure, and the portion of the touch pattern surrounding the at least one light-emitting structure being symmetrically arranged at least with respect to a first axis of symmetry.

[0139] In some examples, the arrangement of multiple grids is the same as the arrangement of multiple isolation openings. In other examples, a grid is set around multiple isolation openings, and a light-emitting structure can be placed in each isolation opening.

[0140] The touch pattern is arranged symmetrically around at least one portion of the light-emitting structure, at least with respect to a first axis of symmetry. In other words, a grid of the touch pattern surrounds a group of light-emitting units, and the periphery of the group of light-emitting units has symmetrical touch traces 41 in a second direction. Of course, the periphery of a group of light-emitting units may also have symmetrical touch traces 41 in the first direction or other directions.

[0141] Figure 4 yes Figure 1 Another enlarged structural diagram of Q. Figure 5 yes Figure 1 Another enlarged structural diagram of Q.

[0142] In some alternative embodiments, please refer to Figures 3 to 5 Within the light-emitting unit group E0, at least one light-emitting structure includes 2N+1 light-emitting structures. The orthogonal projection of the touch trace 41 in the thickness direction Z is symmetrically arranged with respect to the second axis of symmetry N2 parallel to the second direction Y. The second axis of symmetry N2 passes through the centroid of the N+1th light-emitting structure. N≥0. The second direction Y and the first direction X are both perpendicular to the thickness direction Z.

[0143] For example, the light-emitting unit group E0 includes an odd number of light-emitting structures, and the touch traces 41 are symmetrically arranged with respect to the second axis of symmetry N2 when projected onto the thickness direction Z, so that touch traces 41 are provided on both opposite sides of the light-emitting structures along the first direction X. Optionally, in the light-emitting unit group E0, each light-emitting structure has touch traces 41 on both opposite sides along the first direction; or, in the light-emitting unit group E0, the side of the i-th light-emitting structure facing away from the j-th light-emitting structure has touch traces 41, and the side of the j-th light-emitting structure facing away from the i-th light-emitting structure has touch traces 41; or, in the light-emitting unit group E0, the side of the first light-emitting structure facing away from the 2N+1-th light-emitting structure has touch traces 41, and the side of the 2N+1-th light-emitting structure facing away from the first light-emitting structure has touch traces 41. 1≤i<j≤2N+1.

[0144] Optionally, the light-emitting unit group E0 includes 1, 3, 5, 7 or other odd number of light-emitting structures.

[0145] In this embodiment of the application, the above-mentioned arrangement enables touch traces 41 to be provided on both sides of the light-emitting structure along the first direction X, thereby reducing the color shift difference of the display panel in the first direction X and improving the display performance of the display panel.

[0146] In some alternative embodiments, please refer to Figure 3 and Figure 4 N=0, within the light-emitting unit group E0, at least one light-emitting structure includes a light-emitting structure, the orthogonal projection of the touch trace 41 in the thickness direction Z is symmetrically arranged with respect to the second axis of symmetry N2 parallel to the second direction Y, and the second axis of symmetry N2 is arranged through the centroid of the light-emitting structure.

[0147] For example, when the light-emitting unit group E0 includes a light-emitting structure, the light-emitting structure is provided with touch traces 41 on both sides along the first direction X. On this basis, the light-emitting structure is provided with touch traces 41 on both sides along the second direction Y, so that the orthogonal projection of the touch traces 41 in the thickness direction Z surrounds the periphery of the light-emitting structure, thereby reducing the viewing angle difference of the display panel in the first direction X and the second direction Y.

[0148] Optionally, the touch traces 41 arranged on both sides of the light-emitting structure along the first direction X and the touch traces 41 arranged on both sides of the light-emitting structure along the second direction Y can be connected to each other, or they can be disconnected.

[0149] In some alternative embodiments, please refer to Figure 3 and Figure 5N=1. Within the light-emitting unit group E0, at least one light-emitting structure includes three light-emitting structures. The orthogonal projection of the touch trace 41 in the thickness direction Z is symmetrically arranged with respect to the second axis of symmetry N2. The second axis of symmetry N2 is arranged through the centroid of the second light-emitting structure along the first direction X.

[0150] For example, when the light-emitting unit group E0 includes three light-emitting structures, touch traces 41 are provided on both sides of the three light-emitting structures along the second direction Y; or, touch traces 41 are provided only on the opposite or opposite sides of the two light-emitting structures located at both ends. Based on this, touch traces 41 are provided on both sides of the light-emitting structures along the second direction Y so that the orthographic projection of the touch traces 41 in the thickness direction Z surrounds the periphery of the light-emitting structure, thereby reducing the viewing angle deviation difference of the display panel in the first direction X and the second direction Y.

[0151] Figure 6 yes Figure 1 Another enlarged structural diagram of Q.

[0152] In some alternative embodiments, please refer to Figure 6 Within the light-emitting unit group E0, at least one light-emitting structure includes 2N light-emitting structures. The orthogonal projection of the touch trace 41 in the thickness direction Z is symmetrically arranged with respect to the third axis of symmetry N3 parallel to the second direction Y. The third axis of symmetry N3 is located between the Nth light-emitting structure and the (N+1)th light-emitting structure, and N > 0. The second direction Y and the first direction X are both perpendicular to the thickness direction Z.

[0153] For example, the light-emitting unit group E0 includes an even number of light-emitting structures. The orthographic projection of the touch traces 41 in the thickness direction Z is symmetrically arranged around the third axis of symmetry N3, so that touch traces 41 are provided on both opposite sides of the light-emitting structures along the first direction X. Optionally, in the light-emitting unit group E0, each light-emitting structure is provided with touch traces 41 on both opposite sides along the first direction X; or, in the light-emitting unit group E0, the side of the i-th light-emitting structure facing away from the j-th light-emitting structure is provided with touch traces 41, and the side of the j-th light-emitting structure facing away from the i-th light-emitting structure is provided with touch traces 41; or, in the light-emitting unit group E0, the side of the first light-emitting structure facing away from the 2N-th light-emitting structure is provided with touch traces 41, and the side of the 2N-th light-emitting structure facing away from the first light-emitting structure is provided with touch traces 41. 1≤i<j≤2N.

[0154] Optionally, the light-emitting unit group E0 includes 2, 4, 6, 8 or other even number of light-emitting structures.

[0155] In this embodiment of the application, the above-mentioned arrangement enables touch traces 41 to be provided on both sides of the light-emitting structure along the first direction X, thereby reducing the color shift difference of the display panel in the first direction X and improving the display performance of the display panel.

[0156] In some alternative embodiments, please refer to Figure 6 N=1. Within the light-emitting unit group E0, at least one light-emitting structure includes two light-emitting structures. The orthogonal projection of the touch trace 41 in the thickness direction Z is symmetrically arranged with respect to the third axis of symmetry N3, which is located between the first light-emitting structure and the second light-emitting structure.

[0157] For example, when the light-emitting unit group E0 includes two light-emitting structures, touch traces 41 are provided on both sides of the two light-emitting structures along the second direction Y; or, touch traces 41 are provided only on the opposite or facing sides of the two light-emitting structures located at both ends. Based on this, touch traces 41 are provided on both sides of the light-emitting structures along the second direction Y so that the orthographic projection of the touch traces 41 in the thickness direction Z surrounds the periphery of the light-emitting structure, thereby reducing the viewing angle deviation difference of the display panel in the first direction X and the second direction Y.

[0158] Figure 7 yes Figure 1 Another enlarged structural diagram of Q.

[0159] In some alternative embodiments, please refer to Figure 7 At least a portion of the orthographic projection of the touch trace 41 in the thickness direction Z is arranged around a plurality of light-emitting structures and is symmetrically arranged with respect to a first axis of symmetry N1 parallel to the first direction X. The first axis of symmetry N1 passes through the centroid of the plurality of light-emitting structures. The side of the light-emitting structure located at one end of the light-emitting unit group E0 along the first direction X that is away from the side of the light-emitting structure located at the other end of the light-emitting unit group E0 along the first direction X does not have a touch trace 41.

[0160] For example, the light-emitting unit group E0 includes multiple light-emitting structures. Each light-emitting structure has touch traces 41 on both sides along the second direction Y. Furthermore, in the light-emitting unit group E0, neither the side of the first light-emitting structure facing away from the last light-emitting structure nor the side of the last light-emitting structure facing away from the first light-emitting structure has touch traces 41. The light-emitting structure located at one end of the light-emitting unit group E0 along the first direction X is the first light-emitting structure, and the light-emitting structure located at the other end of the light-emitting unit group E0 along the first direction X is the last light-emitting structure.

[0161] Optionally, the first direction X and the second direction Y are set perpendicularly.

[0162] In this embodiment, the above-mentioned arrangement helps to reduce the space occupied by the touch trace 41 in the touch layer 40, thereby reducing the light blockage by the touch trace 41 and improving the display brightness of the display panel.

[0163] In some alternative embodiments, please refer to Figure 4 The orthogonal projection of the touch trace 41 in the thickness direction Z completely surrounds the isolation opening 21, and is symmetrically arranged with respect to the first axis of symmetry N1 and the second axis of symmetry N2. The second axis of symmetry N2 is parallel to the second direction Y, and the second direction Y intersects the first direction X.

[0164] For example, each isolation opening 21 is surrounded by a touch trace 41, and the orthographic projection shape of the touch trace in the thickness direction Z is a continuous closed shape. Furthermore, the touch trace 41 is symmetrically arranged on both sides of the isolation opening 21 in the first direction X and on both sides of the isolation opening 21 in the second direction Y.

[0165] In this embodiment, by completely surrounding the isolation opening 21 with the touch trace 41, the range of light emitted by the light-emitting structure within the isolation opening 21 is consistent in any direction under the influence of the touch trace 41, thereby reducing color shift differences at different viewing angles and further improving the display performance of the display panel.

[0166] Figure 8 yes Figure 1 Another enlarged structural diagram of Q. Figure 9 yes Figure 1 Another enlarged structural diagram of Q. Figure 10 yes Figure 1 Another enlarged structural diagram of Q.

[0167] In some alternative embodiments, please refer to Figures 8 to 10 The isolation structure 20 also includes a through hole 22, with a through hole 22 provided between at least two adjacent isolation openings 21, and the orthogonal projection of the touch trace 41 in the thickness direction Z completely surrounds the through hole 22.

[0168] Optionally, the orthographic projection shape of the through hole 22 along the thickness direction Z can be similar to the orthographic projection shape of the isolation opening 21 along the thickness direction Z. Of course, it can also be a different shape. For example, the orthographic projection shape of the through hole 22 along the thickness direction Z is a rectangle or a square, and the orthographic projection shape of the isolation opening 21 along the thickness direction Z is an ellipse.

[0169] In some examples, a through hole 22 is provided between every two adjacent isolation openings 21. In other examples, the multiple isolation openings 21 include two parts, in which a through hole 22 is provided between two adjacent isolation openings 21 in one part, and in which a through hole 22 is not provided between two adjacent isolation openings 21 in the other part.

[0170] The orthographic projection of the touch trace 41 in the thickness direction Z completely surrounds the via 22. In other words, the orthographic projection shape of the touch trace 41 in the thickness direction Z is a continuous closed shape.

[0171] This application embodiment improves the light transmittance of the display panel by setting through holes 22, and the touch traces 41 are set to completely surround the through holes 22, which helps to reduce the possibility of the touch traces 41 blocking the through holes 22 from the front, and reduces the difference in light intensity received by the photosensitive device through the through holes 22 at different viewing angles.

[0172] In some alternative embodiments, please refer to Figure 10 and Figure 11 The multiple light-emitting unit groups E0 include a first light-emitting structure group E1 that emits a first color light, a second light-emitting structure group E2 that emits a second color light, and a third light-emitting structure group E3 that emits a third color light. The first light-emitting structure group E1 includes at least one first light-emitting structure 31, the second light-emitting structure group E2 includes at least one second light-emitting structure 32, and the third light-emitting structure group E3 includes at least one third light-emitting structure 33. The first color light, the second color light, and the third color light are all different from each other.

[0173] Optionally, the first color light, the second color light, and the third color light can be red, blue, and green, respectively.

[0174] Optionally, the first light-emitting structure group E1 may include one or more first light-emitting structures 31. The second light-emitting structure group E2 may include one or more second light-emitting structures 32. The third light-emitting structure group E3 may include one or more third light-emitting structures 33.

[0175] This application embodiment sets up a first light-emitting structure group E1, a second light-emitting structure group E2, and a third light-emitting structure group E3, and sets up touch traces 41 around the first light-emitting structure group E1, the second light-emitting structure group E2, and the third light-emitting structure group E3, which helps to reduce the color shift difference of different colors of light at different viewing angles and improve the display performance of the display panel.

[0176] Figure 11 yes Figure 1 Another enlarged structural diagram of Q.

[0177] In some alternative embodiments, please refer to Figure 10 and Figure 11 The first light-emitting structure 31 and the second light-emitting structure 32 are alternately arranged along the first direction X to form a first light-emitting column, and the third light-emitting structure 33 is sequentially arranged along the first direction X to form a second light-emitting column. The first light-emitting column and the second light-emitting column are alternately arranged along the second direction Y. The first light-emitting structure 31 of one of the two adjacent first light-emitting columns and the second light-emitting structure 32 of the other are sequentially arranged along the second direction Y.

[0178] For example, a first light-emitting column is provided on both sides of the second light-emitting column in the second direction Y, and the two first light-emitting columns are a first first light-emitting column and a second first light-emitting column. In some examples, the first light-emitting structure 31 in the first first light-emitting column and the first light-emitting structure 31 in the second first light-emitting column are arranged opposite each other in the second direction Y. The second light-emitting structure 32 in the first first light-emitting column and the second light-emitting structure 32 in the second first light-emitting column are arranged opposite each other in the second direction Y. In other examples, the first light-emitting structure 31 in the first first light-emitting column and the second light-emitting structure 32 in the second first light-emitting column are arranged opposite each other in the second direction Y. The second light-emitting structure 32 in the first first light-emitting column and the first light-emitting structure 31 in the second first light-emitting column are arranged opposite each other in the second direction Y. Here, "relative arrangement" can mean that the line connecting the geometric centers of the two light-emitting structures is parallel to the second direction Y.

[0179] Furthermore, the third light-emitting structure 33 in the second light-emitting column is located between the adjacent first light-emitting structure 31 and the second light-emitting structure 32 in the first light-emitting column.

[0180] In some examples, the plane parallel to the thickness direction Z and perpendicular to the second direction Y is the first plane, and the orthographic projection of the third light-emitting structure 33 in the second light-emitting column is located between the orthographic projection of the first light-emitting structure 31 in the first light-emitting column and the orthographic projection of the second light-emitting structure 32 in the first plane.

[0181] For example, the line connecting the midpoint of the geometric center of the adjacent first light-emitting structure 31 and the second light-emitting structure 32 in the first light-emitting column and the geometric center of the third light-emitting structure 33 is arranged parallel to the second direction Y.

[0182] The embodiments of this application, through the above-described settings, are beneficial to improving the space utilization rate of the light-emitting structure in the display panel and increasing the pixel density.

[0183] Figure 12 yes Figure 1 Another enlarged structural diagram of Q. Figure 13 yes Figure 12 A schematic diagram of an enlarged structure of P.

[0184] In some alternative embodiments, please refer to Figure 12and Figure 13 The light-emitting layer includes multiple pixel units arranged in a repeating pattern. Each pixel unit has a virtual quadrilateral. Multiple virtual quadrilaterals are arranged in rows and columns. Two opposite vertices of the virtual quadrilaterals along the first direction X coincide with the center of a first light-emitting structure 31 and a second light-emitting structure 32, respectively. The other two opposite vertices along the second direction Y coincide with the center of two third light-emitting structures 33, respectively. The first direction X and the second direction Y are set perpendicularly.

[0185] Optionally, multiple pixel units are arranged in an array along the first direction X and the second direction Y.

[0186] For example, the geometric centers of a first light-emitting structure 31 and a second light-emitting structure 32 are arranged opposite each other along a first direction X, and the geometric centers of two third light-emitting structures 33 are arranged opposite each other along a second direction Y. Furthermore, the four geometric centers of the first light-emitting structure 31, the second light-emitting structure 32, and the two third light-emitting structures 33 form the four vertices of a virtual quadrilateral.

[0187] The embodiments of this application arrange the light-emitting structures in the pixel unit according to the vertices of a virtual quadrilateral, which helps to simplify the overall structure of the pixel unit, improve the arrangement shape of the pixel unit, and enhance the applicability of the display panel.

[0188] In some alternative embodiments, the shapes of the first light-emitting structure 31, the second light-emitting structure 32, and the third light-emitting structure 33 include one or more combinations of circles, rectangles, and ellipses, which is beneficial to increasing the arrangement of the light-emitting structures and improving the applicability of the display panel.

[0189] Optionally, the shape of the first light-emitting structure 31 includes one or more combinations of circles, rectangles, rhombuses, and ellipses.

[0190] Optionally, the shape of the second light-emitting structure 32 includes one or more combinations of circles, rectangles, rhombuses, and ellipses.

[0191] Optionally, the shape of the third light-emitting structure 33 includes one or more combinations of circles, rectangles, rhombuses, and ellipses.

[0192] Optionally, the first light-emitting structure 31, the second light-emitting structure 32, and the third light-emitting structure 33 may have the same shape, and their areas may be the same or different. For example, the areas of the light-emitting structures corresponding to different colors of light are different.

[0193] In some alternative embodiments, please refer to Figure 9 and Figure 10 A through hole 22 is provided between two adjacent isolation openings 21 in one of the first light-emitting columns and the second light-emitting column.

[0194] In some examples, a through hole 22 is provided between two adjacent isolation openings 21 in the first light-emitting column. In other examples, a through hole 22 is provided between two adjacent isolation openings 21 in the second light-emitting column.

[0195] In this embodiment of the application, the through hole 22 can be arranged according to different design requirements to meet different light transmission needs.

[0196] In some alternative embodiments, please refer to Figure 9 One of the two adjacent columns of the first light-emitting column is provided with the through hole 22.

[0197] For example, the second light-emitting column is provided with two first light-emitting columns on both sides along the second direction Y. The two first light-emitting columns can be a first first light-emitting column and a second first light-emitting column. In some examples, a through hole 22 is provided between two adjacent isolation openings 21 in the first first light-emitting column. In other examples, a through hole 22 is provided between two adjacent isolation openings 21 in the second first light-emitting column.

[0198] In some alternative embodiments, please refer to Figure 11 The light-emitting unit 30 includes a first type of light-emitting column D1, a second type of light-emitting column D2, and a third type of light-emitting column D3. In the first type of light-emitting column D1 and the second type of light-emitting column D2, a through-hole 22 is provided between two adjacent isolation openings 21. In the first type of light-emitting column D1, the orthogonal projection of the touch trace 41 in the thickness direction Z surrounds both the isolation opening 21 and the through-hole 22. In the second type of light-emitting column D2, the isolation opening 21 and the through-hole 22 are jointly surrounded by the orthogonal projection of the touch trace 41 in the thickness direction Z. In the third type of light-emitting column D3, multiple isolation openings 21 are jointly surrounded by the orthogonal projection of the touch trace 41 in the thickness direction Z.

[0199] Optionally, the first type of light-emitting column D1 can be the first light-emitting column, or of course, it can be the second light-emitting column.

[0200] Optionally, the second type of light-emitting column D2 can be the first light-emitting column, or of course, it can be the second light-emitting column.

[0201] Optionally, the third type of light-emitting column D3 can be the first light-emitting column, or of course, the second light-emitting column.

[0202] In the first type of light-emitting column D1 and the second type of light-emitting column D2, a through hole 22 is provided between two adjacent isolation openings 21. In the third type of light-emitting column D3, a through hole 22 may not be provided between two adjacent isolation openings 21, but a through hole 22 may also be provided.

[0203] In the first type of light-emitting column D1, the orthogonal projection of the touch trace 41 in the thickness direction Z surrounds the isolation opening 21 and the through hole 22 respectively. In other words, in the first type of light-emitting column D1, touch traces 41 are provided around the isolation opening 21 and touch traces 41 are provided around the through hole 22.

[0204] Within the second type of light-emitting array D2, the isolation opening 21 and the through hole 22 are both surrounded by the orthogonal projection of the touch trace 41 in the thickness direction Z. In other words, within the second type of light-emitting array D2, no touch trace 41 is provided between the isolation opening 21 and the through hole 22. Touch trace 41 can be provided on the remaining outer periphery of the isolation opening 21, and touch trace 41 can be provided on the remaining outer periphery of the through hole 22. Here, "remaining outer periphery" refers to the side of the periphery of the isolation opening 21 excluding the area between the isolation opening 21 and the through hole 22, and the side of the periphery of the through hole 22 excluding the area between the isolation opening 21 and the through hole 22.

[0205] Within the third type of light-emitting column D3, multiple isolation openings 21 are collectively surrounded by the orthogonal projection of touch traces 41 in the thickness direction Z. In other words, within the third type of light-emitting column D3, touch traces 41 are not provided between the isolation openings 21, but can be provided on the remaining outer periphery of the isolation openings 21. Here, "remaining outer periphery" refers to the periphery of the isolation openings 21, excluding the side between the isolation openings 21.

[0206] In these alternative embodiments, the first type of light-emitting column D1, the second type of light-emitting column D2, and the third type of light-emitting column D3 can be arranged in a targeted manner according to design requirements to specifically improve local brightness, reduce color shift differences at different viewing angles, and improve the display effect of the display panel.

[0207] In some alternative embodiments, please refer to Figure 12 and Figure 13 The first light-emitting structure 31, the second light-emitting structure 32, and the third light-emitting structure 33 are all rectangular in shape. In the first light-emitting column, the apex corners of the first light-emitting structure 31 and the second light-emitting structure 32 are arranged opposite each other along the first direction X. In the second light-emitting column, the apex corners of two adjacent third light-emitting structures 33 are arranged opposite each other along the first direction X. The through hole 22 is disposed between adjacent first light-emitting structures 31 and second light-emitting structures 32 in the first light-emitting column; and / or, the through hole 22 is disposed between two adjacent third light-emitting structures 33 in the second light-emitting column.

[0208] In some examples, the through-hole 22 is disposed between adjacent first light-emitting structures 31 and second light-emitting structures 32 within the first light-emitting column. In other examples, the through-hole 22 is disposed between two adjacent third light-emitting structures 33 within the second light-emitting column. In still other examples, the through-hole 22 is disposed between adjacent first light-emitting structures 31 and second light-emitting structures 32 within the first light-emitting column, and also between two adjacent third light-emitting structures 33 within the second light-emitting column.

[0209] In these alternative embodiments, by setting the light-emitting structure as a rectangle and setting the apex corners of adjacent light-emitting structures in the same column to be opposite each other, the spacing of the light-emitting structures in the second direction Y is shortened, thereby increasing the pixel density and improving the display effect of the display panel.

[0210] In some alternative embodiments, please refer to Figure 12 and Figure 13 The touch trace 41 surrounding the through hole 22 is rectangular in shape, and the apex of any one of the first light-emitting structure 31, the second light-emitting structure 32 and the third light-emitting structure 33 is set opposite to the opposite side of the touch trace 41 surrounding the through hole 22.

[0211] For example, the apex corner of the first light-emitting structure 31 is positioned opposite to the opposite side of the touch trace 41 surrounding the through hole 22. The apex corner of the second light-emitting structure 32 is positioned opposite to the opposite side of the touch trace 41 surrounding the through hole 22. The apex corner of the third light-emitting structure 33 is positioned opposite to the opposite side of the touch trace 41 surrounding the through hole 22.

[0212] The embodiments of this application, through the above-described configuration, help to reduce the range of light emitted from the apex, thereby improving the uniformity of the light intensity emitted from the apex and the light intensity emitted from the opposite side.

[0213] In some alternative embodiments, please refer to Figure 12 and Figure 13 The orthographic projection of the touch trace 41 in the thickness direction Z is arranged around the periphery of the isolation opening 21 and the periphery of the through hole 22. The touch trace 41 includes a first segment 411 and a second segment 412. The orthographic projection of the first segment in the thickness direction Z and the orthographic projection of the second segment 412 in the thickness direction Z are arranged together around the through hole 22 between two adjacent isolation openings 21. The line connecting the centers of two adjacent light-emitting structures is perpendicular to the first segment 411 and parallel to the second segment 412.

[0214] Optionally, the through hole 22 is rectangular in shape, and the shape formed by the first segment 411 and the second segment 412 is also rectangular. Optionally, there are two first segments 411 and two second segments 412.

[0215] For example, the first segment 411 touch trace 41 is perpendicular to the line connecting the geometric centers of the two adjacent light-emitting structures. Furthermore, the second segment 412 touch trace 41 is parallel to the line connecting the geometric centers of the two adjacent light-emitting structures. Here, "two adjacent light-emitting structures" refers to the light-emitting structures adjacent to the first segment 411.

[0216] In some alternative embodiments, please refer to Figure 12 and Figure 13 Multiple light-emitting structures are arranged in columns along the first direction X and in rows along the second direction Y. In the same column, the line connecting the centers of two adjacent light-emitting structures is perpendicular to the first segment 411, and the line connecting the centers of two adjacent light-emitting structures is parallel to the second segment 412. Furthermore, the line connecting the center of either the first light-emitting structure 31 or the second light-emitting structure 32 in the first light-emitting column with the center of the third light-emitting structure 33 in the second light-emitting column is perpendicular to the touch trace 41 between the first light-emitting structure 31 or the second light-emitting structure 32 and the third light-emitting structure 33.

[0217] Optionally, within the same column, the center line connecting two adjacent light-emitting structures is the first connecting line L1, the center line connecting the first light-emitting structure 31 in the first light-emitting column and the center line connecting the third light-emitting structure 33 in the second light-emitting column is the second connecting line L2, and the center line connecting the second light-emitting structure 32 in the first light-emitting column and the center line connecting the third light-emitting structure 33 in the second light-emitting column is the third connecting line L3.

[0218] For example, the first connection line L1 is set perpendicular to the first segment 411.

[0219] For example, the second connection line L2 is perpendicular to the touch trace 41 between the first light-emitting structure 31 and the third light-emitting structure 33.

[0220] For example, the third connection line L3 is perpendicular to the touch trace 41 between the second light-emitting structure 32 and the third light-emitting structure 33.

[0221] In these alternative embodiments, the above-described arrangement helps to simplify the arrangement of the touch traces 41, reduce the difficulty of arranging the touch traces 41, and improve the production efficiency of the display panel.

[0222] In some alternative embodiments, please refer to Figure 13 The spacing between one of the two adjacent isolation openings 21 and the through hole 22 is equal to the spacing between the other and the through hole, and the orthogonal projection of the touch trace 41 in the thickness direction Z is arranged around the periphery of the through hole 22.

[0223] For example, a through hole 22 is provided between two adjacent isolation openings 21. The two isolation openings 21 are a first isolation opening 21 and a second isolation opening 22. The distance between the first isolation opening and the through hole 22 and the distance between the second isolation opening 21 and the through hole 22 are equal. Furthermore, the orthographic projection of the touch trace 41 in the thickness direction Z is arranged around the periphery of the through hole 22 to reduce the impact of the touch trace 41 on the light transmission performance of the through hole 22 while improving the color shift difference of different isolation openings 21 under different viewing angles.

[0224] In some alternative embodiments, please refer to Figure 3 and Figure 4 The isolation structure 20 includes a first isolation portion 23 and a second isolation portion 24 located on the side of the first isolation portion away from the substrate. The second isolation portion encloses and forms an isolation sub-opening 211. The first light-emitting structure 31 and the second light-emitting structure 32 are arranged adjacent to each other. The orthographic projection of the touch trace 41 in the thickness direction Z is located between the adjacent first light-emitting structure 31 and the second light-emitting structure 32. The distance between the inner wall of the isolation sub-opening 211 on the side of the first light-emitting structure 31 near the second light-emitting structure 32 and the orthographic projection of the touch trace 41 in the thickness direction Z is equal to the distance between the inner wall of the isolation sub-opening 211 on the side of the second light-emitting structure 32 near the first light-emitting structure 31 and the orthographic projection of the touch trace 41 in the thickness direction Z.

[0225] For example, the first isolation portion 23 and the second isolation portion 24 together enclose to form an isolation opening 21, and the second isolation portion 24 encloses to form an isolation sub-opening 211.

[0226] The inner wall of the isolator opening 211 on the side of the first light-emitting structure 31 closest to the second light-emitting structure 32 is also the side wall of the second isolation portion 24 surrounding the first light-emitting structure 31 closest to the second light-emitting structure 32. Optionally, this side wall can be the first side wall. The inner wall of the isolator opening 211 on the side of the second light-emitting structure 32 closest to the first light-emitting structure 31 is also the side wall of the second isolation portion 24 surrounding the second light-emitting structure 32 closest to the first light-emitting structure 31. Optionally, this side wall can be the second side wall. The distance between the first side wall and the orthogonal projection of the touch trace 41 in the thickness direction Z is equal to the distance between the second side wall and the orthogonal projection of the touch trace 41 in the thickness direction Z, so as to reduce the number of touch traces 41 arranged between two adjacent light-emitting structures, thereby reducing the impact of the touch traces 41 on the light-emitting structure.

[0227] Figure 14 yes Figure 1 Another enlarged structural diagram of Q. Figure 15 yes Figure 14 A schematic diagram of an enlarged structure of R in the diagram.

[0228] In some alternative embodiments, please refer to Figure 14 and Figure 15 The touch trace 41 includes a touch conductive part 42 and a virtual conductive part 43. Multiple touch conductive parts are electrically connected to each other to form a touch electrode 44. The virtual conductive part 43 is spaced apart from the touch conductive part 42.

[0229] In this embodiment, the touch electrode 44 includes a sensing electrode and a transmitting electrode. The multiple touch conductive parts 42 may include two parts: one part of the touch conductive part 42 forms a sensing electrode, and the other part of the touch conductive part 42 forms a transmitting electrode. The two parts of the touch conductive part 42 are insulated from each other and are arranged adjacent to each other.

[0230] In some embodiments, the virtual conductive part 43 can be disposed within the touch electrode 44. In other words, the virtual conductive part 43 can be disposed within the sensing electrode or the emitting electrode. By disposing the virtual conductive part 43 within the touch electrode 44, the parasitic capacitance generated between the touch electrode and other conductive film layers can be reduced, thereby reducing the impact of parasitic capacitance on the touch function. Furthermore, disposing the virtual conductive part 43 can also reduce the difference in the range of light emitted by the light-emitting unit 30 from different viewing angles, thereby reducing the possibility of color shift in the display screen.

[0231] In some alternative embodiments, please refer to Figure 15 The touch conductive part 42 includes a first sub-part 421 and a second sub-part 422. The first sub-part is located on at least one side of the isolation opening 21. In the thickness direction Z, the orthographic projection of the second sub-part 422 surrounds the orthographic projection of the through hole 22 and is connected to the first sub-part 421.

[0232] Optionally, the second sub-parts 422 of two adjacent through holes 22 can be connected by the first sub-parts 421.

[0233] In the thickness direction Z, the orthographic projection of the first sub-part 421 is located on at least one side of the orthographic projection of the isolation opening 21. Taking the orthographic projection shape of the isolation opening as a circle as an example, the first sub-part 421 can be located on one side of the isolation opening 21 along the first direction X, or the first sub-part 421 can be located on one side of the isolation opening 21 along the second direction Y, or the first sub-part 421 can be arranged around the isolation opening 21. The first sub-part blocks the light emitted by the light-emitting unit 30 in the isolation opening. The first sub-part 421 can be arranged on the periphery of the isolation opening 21 according to the design requirements, so that the range of light emitted by the light-emitting unit 30 can meet different design requirements.

[0234] In the thickness direction Z, the orthographic projection of the second sub-part 422 surrounds the orthographic projection of the through hole 22, thereby reducing the possibility of the second sub-part 422 blocking the through hole 22 and thus improving the light transmittance of the through hole. The first sub-part 421 and the second sub-part 422 are connected to increase the effective area of ​​the touch electrode 44 formed by the touch conductive part 42, thereby improving the touch sensitivity.

[0235] In some embodiments, please refer to Figure 14 and Figure 15 In the thickness direction Z, the orthographic projection of the first sub-part 421 and the orthographic projection of the second sub-part 422 are arranged together around the orthographic projection of the isolation opening 21.

[0236] In this embodiment, the second sub-part 422 is not only arranged around the through hole 22, but at least part of the second sub-part is also located between the through hole 22 and the isolation opening 21. The orthographic projection of the first sub-part 421 and the orthographic projection of the second sub-part 422 are arranged together around the orthographic projection of the isolation opening 21, thereby reducing the difficulty of arranging the touch wiring 41 and further reducing the difference in the range of light emitted by the light-emitting unit 30 under different viewing angles.

[0237] Optionally, the orthographic shape of the second sub-part 422 may be, but is not limited to, annular, semi-annular, or strip-shaped.

[0238] In some embodiments, please refer to Figure 14 and Figure 15 The virtual conductive portion 43 includes a third sub-portion 431 and a fourth sub-portion 432. The fourth sub-portion is disposed around at least one through hole 22. The third sub-portion 431 is connected to the fourth sub-portion 432 and extends along the interior away from the fourth sub-portion.

[0239] In this embodiment, the third sub-part 431 extends inward away from the fourth sub-part 432. In other words, taking a rectangle as an example, the orthographic projection shape of the fourth sub-part 432 along the thickness direction Z, the third sub-part 431 can extend inward away from the side edge of the rectangle, or it can extend inward away from the corner of the rectangle. Of course, in other examples, the orthographic projection shape of the fourth sub-part 432 along the thickness direction Z can also include a circle, a square, a triangle, or other shapes.

[0240] Optionally, the fourth sub-parts 432 of two adjacent through holes 22 can be connected by the third sub-parts 431.

[0241] In the thickness direction Z, the orthographic projection of the third sub-part 431 is located on at least one side of the orthographic projection of the isolation opening 21. Taking the orthographic projection shape of the isolation opening as a circle as an example, the third sub-part 431 can be located on one side of the isolation opening 21 along the first direction X, or the third sub-part 431 can be located on one side of the isolation opening 21 along the second direction Y, or the third sub-part 431 can be arranged around the isolation opening 21. The third sub-part blocks the light emitted by the light-emitting unit 30 in the isolation opening. The third sub-part 431 can be arranged on the periphery of the isolation opening 21 according to the design requirements, so that the range of light emitted by the light-emitting unit 30 can meet different design requirements.

[0242] In the thickness direction Z, the orthographic projection of the fourth sub-part 432 is arranged around the orthographic projection of the through hole 22, thereby reducing the possibility of the fourth sub-part 432 blocking the through hole 22 and thus improving the light transmittance of the through hole.

[0243] In some embodiments, please refer to Figure 15 The fourth sub-part 432 is connected to a plurality of third sub-parts 431 with intervals.

[0244] Optionally, the plurality of third sub-parts 431 connected to the fourth sub-part 432 may be disposed between different isolation openings 21. Of course, at least some of the plurality of third sub-parts 431 connected to the fourth sub-part 432 may also be located between two adjacent isolation openings 21.

[0245] As an example, a plurality of isolation openings 21 are distributed around the through hole 22, and the number of the plurality of third sub-parts 431 connected to the fourth sub-part 432 is equal to the number of the plurality of isolation openings 21 distributed around the through hole 22 enclosed by the fourth sub-part 432.

[0246] In this embodiment, by setting multiple third sub-parts 431 on the fourth sub-part 432, the space occupied by the virtual electrode in the touch electrode 44 can be increased, further reducing the possibility of the touch electrode forming parasitic capacitance with other conductive film layers. In addition, the multiple third sub-parts 431 can effectively balance the difference in the light emission range emitted by the light-emitting unit 30 under different viewing angles.

[0247] In some alternative embodiments, please refer to Figure 3 The isolation structure 20 includes a first isolation portion 23 and a second isolation portion 24 located on the side of the first isolation portion away from the substrate. The orthographic projection of the first isolation portion 23 onto the substrate is located within the orthographic projection of the second isolation portion 24 onto the substrate.

[0248] Optionally, the orthographic projection of the touch trace 41 along the thickness direction Z and the orthographic projection of the second isolation portion 24 along the thickness direction Z are at least partially overlapped.

[0249] A light-emitting unit 30 and a first electrode 60 can be formed in the isolation opening 21. The first electrode is located on the side of the light-emitting unit 30 facing away from the array substrate 10. The first electrode 60 can be electrically connected to the isolation structure 20, and the first electrode 60 can exchange signals with the driving chip through the isolation structure 20. Optionally, the first electrode 60 includes a cathode.

[0250] The specific dimensions and shapes of the first isolation portion 23 and the second isolation portion 24 are not limited in this embodiment of the invention. Exemplarily, the longitudinal section of the isolation structure 20 can be larger at the top and smaller at the bottom. This design helps to prevent the light-emitting material and electrode material from extending along the sidewall of the first isolation portion 23 to the sidewall of the second isolation portion 24 during the fabrication of the light-emitting unit 30 and the first electrode 60. This allows for the fabrication and separation of the light-emitting unit 30 and the first electrode 60 within different isolation openings 21 without the need for a fine metal mask.

[0251] The embodiments of the present invention do not limit the material composition of the first isolation part 23 and the second isolation part 24. Both the first isolation part 23 and the second isolation part 24 may include conductive materials, or the first isolation part 23 may include conductive materials and the second isolation part 24 may include insulating materials, as long as the two electrodes can achieve signal transmission by means of the isolation structure 20.

[0252] Figure 16 This is a cross-sectional structural diagram of another display panel provided in an embodiment of this application.

[0253] In some embodiments, please refer to Figure 16 The isolation structure 20 also includes a third isolation section 25, and the first isolation section 23 is located between the third isolation section and the second isolation section 24.

[0254] The isolation structure 20 includes at least a first isolation portion 23, a second isolation portion 24, and a third isolation portion 25. The dimensions and shapes of the first isolation portion 23, the second isolation portion 24, and the third isolation portion 25 are not limited in this embodiment of the invention. For example, the orthographic projection of the first isolation portion 23 onto the array substrate 10 lies within the orthographic projection of the third isolation portion 25 onto the array substrate; that is, the longitudinal cross-sectional shape of the first isolation portion 23, the second isolation portion 24, and the third isolation portion 25 is I-shaped.

[0255] Similar to the first isolation portion 23, the third isolation portion 25 also includes a conductive material. The first electrode 60 can directly contact the third isolation portion 25 to achieve an electrical connection with the first isolation portion 23 via the third isolation portion. Optionally, the first electrode 60 and the third isolation portion 25 are overlapped. Further, the first electrode 60 can be partially located on the side of the third isolation portion 25 facing away from the array substrate 10. The arrangement of the third isolation portion helps to improve the reliability of the electrical connection between the first electrode 60 and the isolation structure 20. For example, the first isolation portion 23 is made of aluminum, the second isolation portion 24 is made of titanium, and the third isolation portion 25 is made of molybdenum.

[0256] In some embodiments, please refer to Figure 16 The display panel also includes a pixel definition layer 70, which is disposed on the array substrate 10. The pixel definition layer includes a pixel limiting portion 71 and a pixel opening 72 defined by the pixel limiting portion. The pixel opening and the isolation opening 21 are connected to accommodate the light-emitting unit 30. The inner wall of each pixel opening 72 is projected onto the substrate in the orthographic projection of the substrate, and the inner wall of each isolation opening 21 is projected onto the array substrate 10 in the orthographic projection of the array substrate 10.

[0257] The pixel definition layer 70 includes a pixel defining portion 71 and a pixel opening 72. The pixel opening is correspondingly disposed to the isolation opening 21. For example, the orthographic projection of the pixel opening 72 onto the array substrate 10 can be located within the orthographic projection of the isolation opening 21 onto the array substrate 10. Part of the structure in the light-emitting unit 30 and the first electrode 60 can be located within the pixel opening 72.

[0258] Figure 17 This is a cross-sectional structural diagram of another display panel provided in an embodiment of this application.

[0259] In some embodiments, please refer to Figure 16 and Figure 17 The isolation structure 20 is disposed on the side of the pixel limiting portion 71 away from the array substrate 10, or the pixel limiting portion 71 is provided with a receiving groove 711, and the isolation structure 20 is disposed in the receiving groove.

[0260] The isolation structure is disposed on the side of the pixel limiting portion 71 away from the array substrate 10, that is, the orthogonal projection of the isolation structure 20 on the array substrate falls within the orthogonal projection of the pixel limiting portion 71 on the array substrate 10, so as to improve the isolation effect of the isolation opening 21 formed by the isolation structure 20.

[0261] A receiving groove 711 is provided on the pixel limiting portion 71, which can be formed by recessing the pixel limiting portion 71 on the side facing away from the array substrate 10. Optionally, the recess depth of the receiving groove 711 can be the same as or different from the recess depth of the pixel opening 72. Optionally, the receiving groove 711 can be provided through the pixel limiting portion 71.

[0262] Optionally, the through hole 22 and the receiving groove 711 are connected.

[0263] Optionally, one or more receiving slots 711 can be provided between two adjacent pixel openings 72. The isolation structure 20 is provided in the receiving slot, which can reduce the space occupied by the isolation structure in the Z-direction of the display panel thickness, thereby reducing the overall thickness of the display panel.

[0264] Figure 18 This is a cross-sectional structural diagram of another display panel provided in an embodiment of this application.

[0265] In some embodiments, please refer to Figure 18 The through-hole 22 extends through the first isolation portion 23 and the second isolation portion 24, so that both the first and second isolation portions are divided into two parts, and the length of the second isolation portion 24 in each part along the direction toward the isolation opening 21 is greater than the length of the first isolation portion 23 in the same direction. Optionally, the side of the second isolation portion 24 and the first isolation portion 23 in each part facing the through-hole 22 can be a flush surface, that is, the inner wall surrounding the through-hole 22 is a flat surface, thereby reducing the possibility that the through-hole is blocked by the isolation structure 20.

[0266] Figure 19 This is a cross-sectional structural diagram of another display panel provided in an embodiment of this application.

[0267] In some embodiments, please refer to Figure 19 Two or more stacked first isolation parts 23 and second isolation parts 24 are provided between adjacent isolation openings 21, and a through hole 22 is provided between the two or more stacked first isolation parts 23 and second isolation parts 24.

[0268] In this embodiment, both sides of the through hole can be a first isolation portion 23 and a second isolation portion 24 with a longitudinal cross-section that is larger at the top and smaller at the bottom. This design helps to make it difficult for the light-emitting material and the electrode material to be connected together when they fall into the through hole 22 during the preparation of the light-emitting unit 30 and the first electrode 60, thereby reducing the possibility that the light-emitting material will be lit up in the through hole 22 and cause abnormal display effect.

[0269] In some alternative embodiments, the isolation structure 20 is an insulating structure; in other words, the isolation structure 20 can be a pixel definition layer 70, or the isolation structure is part of the pixel definition layer.

[0270] Figure 20 This is a schematic diagram of the structure of a display panel provided in an embodiment of this application.

[0271] In some alternative embodiments, please refer to Figure 19 and Figure 20The display panel also includes a first display area and a second display area, wherein the light transmittance of the first display area is greater than that of the second display area. Optionally, the through hole 22 and the light-emitting unit group E0 are disposed in the first display area. Optionally, the first display area is a photosensitive area A1, and the second display area is a non-photosensitive area A2.

[0272] Optionally, the second display area may be set around at least a portion of the first display area.

[0273] Optionally, a photosensitive element may be disposed in the first display area. For example, the first display area may be disposed of as a camera, a fingerprint recognition device, or other photosensitive element. External light can be projected onto the photosensitive element through the through-hole 22, so that the photosensitive element can act according to the acquired light.

[0274] Optionally, the through hole 22 can be set in the first display area; of course, the through hole can also be set in the second display area.

[0275] Optionally, the light-emitting unit group E0 can be set in the first display area; of course, the light-emitting unit group E0 can also be set in the second display area.

[0276] like Figures 1 to 3 as well as Figure 20 As shown in the figure, this application embodiment provides a display panel, which includes a first display area and a second display area. The light transmittance of the first display area is greater than that of the second display area. The display panel also includes an array substrate 10, a light-emitting layer, an isolation structure 20, and a touch layer 40. The light-emitting layer is located on one side of the array substrate 10 and includes a plurality of light-emitting units 30. The isolation structure 20 is located on one side of the array substrate 10 and includes an isolation opening and a through hole 22. The light-emitting units 30 are disposed in the isolation opening, and the through hole is disposed in the first display area. The touch layer 40 includes touch traces 41, which are disposed on the side of the isolation structure 20 facing away from the array substrate 10. In the first display area, the orthogonal projection of the touch traces 41 in the thickness direction Z of the display panel is disposed at least around the through hole 22. In the second display area, the orthogonal projection of the touch traces 41 in the thickness direction Z is disposed around the isolation opening 21.

[0277] Optionally, as described above, when the display panel includes a first display area and a second display area, the orthographic projection of the touch trace 41 in the first display area in the thickness direction Z surrounds a portion or all of the through hole 22. The orthographic projection of the touch trace 41 in the second display area in the thickness direction Z surrounds the periphery of the isolation opening 21.

[0278] The array substrate 10, the light-emitting layer, the isolation structure 20, and the touch layer 40 are arranged as described in the above-mentioned display panel embodiment, and will not be repeated here.

[0279] In some alternative embodiments, please refer to Figure 2 The plurality of light-emitting units 30 include a plurality of light-emitting unit groups E0, each light-emitting unit group E0 emitting a single color light, and the light-emitting unit group includes at least one light-emitting structure disposed along a first direction X. At least a portion of the orthogonal projection of the touch trace 41 on the thickness direction Z of the display panel is disposed around at least one light-emitting structure and is symmetrically disposed with respect to a first axis of symmetry N1 passing through at least one light-emitting structure. The first axis of symmetry is parallel to the first direction X and is disposed intersecting the thickness direction Z.

[0280] The arrangement of the light-emitting unit group E0 and the touch layer 40 is as described in the above-mentioned display panel embodiment, and will not be repeated here.

[0281] like Figures 1 to 4 As shown, this application embodiment provides a display panel, which includes an array substrate 10, a light-emitting layer, an isolation structure 20, and a touch layer 40. The light-emitting layer is located on one side of the array substrate 10 and includes a plurality of light-emitting units 30. The isolation structure 20 is located on one side of the array substrate 10 and includes an isolation opening 21, in which the light-emitting units 30 are disposed. The touch layer 40 includes touch traces 41, which are disposed on the side of the isolation structure 20 facing away from the array substrate 10. The orthographic projection of the touch traces 41 in the thickness direction Z of the display panel surrounds the orthographic projection of at least one isolation opening 21 in the thickness direction Z.

[0282] Optionally, as described above, when the display panel includes an isolation opening, the orthographic projection pattern of the touch trace 41 along the thickness direction Z includes, but is not limited to, continuous closed shapes and discontinuous shapes. For example, the orthographic projection shape of the touch trace 41 along the thickness direction Z includes a circular ring or a semi-circular ring. Optionally, in the thickness direction Z, the orthographic projection of the touch trace 41 overlaps with the orthographic projection of the isolation structure 20.

[0283] The array substrate 10, the light-emitting layer, the isolation structure 20, and the touch layer 40 are arranged as described in the above-mentioned display panel embodiment, and will not be repeated here.

[0284] In the display panel and display device provided in this application, by arranging the touch trace 41 around the isolation opening 21, the difference in the range of light emitted by the light-emitting unit 30 in different directions in the isolation opening is reduced, thereby reducing the difference in the brightness of light emitted by the light-emitting unit 30 at different positions under a wide viewing angle, thereby reducing the possibility of color shift in the displayed image.

[0285] In some embodiments, please refer to Figures 14 to 15 The isolation structure 20 also includes a through hole 22, which is disposed between two adjacent isolation openings 21. The orthogonal projection of the touch trace 41 in the thickness direction Z surrounds at least a portion of the orthogonal projection of the through hole 22 in the thickness direction.

[0286] Optionally, the orthographic projection pattern of the through hole along the thickness direction Z can be similar to the orthographic projection pattern of the isolation opening 21 along the thickness direction Z. Of course, it can also be a different pattern. The following example illustrates this by taking the orthographic projection pattern of the through hole 22 along the thickness direction Z as a rectangle or a square, and the orthographic projection pattern of the isolation opening 21 along the thickness direction Z as a circle.

[0287] In this embodiment, the light transmittance of the display panel is improved by setting through holes 22, and the touch traces 41 are arranged around at least part of the through holes 22 to reduce the impact of the touch traces on the light transmittance.

[0288] In some alternative embodiments, four adjacent through holes 22 are arranged around an isolation opening 21.

[0289] For example, the isolation opening 21 is provided with two through holes 22 on both sides along the first direction X, and the isolation opening is provided with two through holes on both sides along the second direction Y.

[0290] In some alternative embodiments, four adjacent isolation openings 21 are arranged around a through hole 22.

[0291] For example, the through hole 22 is provided with two isolation openings 21 on both sides along the first direction X, and the through hole is provided with two isolation openings on both sides along the second direction Y.

[0292] In some embodiments, please refer to Figure 15 The display panel also includes a pixel group, which includes multiple light-emitting units 30 of different colors and multiple through holes 22 distributed around the light-emitting units. Within the pixel group, the multiple through holes 22 include a first through hole 221 and a second through hole 222. Along the thickness direction Z, the orthographic projection of the touch conductive part 42 surrounds the periphery of the orthographic projection of the first through hole 221, and the orthographic projection of the virtual conductive part 43 surrounds the periphery of the orthographic projection of the second through hole 222.

[0293] Optionally, the light-emitting units 30 in the display panel can be arranged in a pixel group manner. For example, a pixel group includes multiple light-emitting units 30 of different colors, and the display panel is arranged in a matrix with pixel groups as the basic units. Multiple through-holes 22 can be provided in each pixel group, with each through-hole located between two adjacent light-emitting units 30.

[0294] Optionally, a pixel group may include one or more pixel units.

[0295] Optionally, the number of first through holes 221 and the number of second through holes 222 can be the same, or they can be different.

[0296] In this embodiment, a virtual conductive part 43 is provided in each pixel group to balance the parasitic capacitance formed by the touch electrode 44 and other conductive film layers and the difference in the light emission range emitted by the light-emitting unit 30 under different viewing angles.

[0297] In some embodiments, please refer to Figure 15 The multiple light-emitting units 30 include a first light-emitting structure 31, a second light-emitting structure 32 and a third light-emitting structure 33. The third light-emitting structure has alternating first light-emitting structures 31 and second light-emitting structures 32 on opposite sides along the first direction X. The second through hole 222 is located between two adjacent third light-emitting structures 33. The first direction X intersects with the thickness direction Z.

[0298] Optionally, the first light-emitting structure 31, the second light-emitting structure 32, and the third light-emitting structure 33 may each have different colors.

[0299] Optionally, the pixel group may include two third light-emitting structures 33, a first light-emitting structure 31, and a second light-emitting structure 32.

[0300] Optionally, the third light-emitting structure 33 includes a first side and a second side along the first direction X. On the first side, the first light-emitting structure 31 and the second light-emitting structure 32 are alternately distributed, and on the second side, the first light-emitting structure 31 and the second light-emitting structure 32 are alternately distributed.

[0301] The second through-hole 222 is located between two adjacent light-emitting units 30. In other words, the second through-hole 222 can be located at the center of the pixel group. In some examples, the orthographic projection of one touch electrode 44 along the thickness direction Z covers the orthographic projection of multiple pixel groups along the thickness direction Z. By placing the second through-hole 222 at the center of the pixel group, the interference of the virtual conductive part 43 on the touch capacitance formed between the two touch electrodes 44 can be reduced.

[0302] In some embodiments, please refer to Figure 19 The display panel also includes an encapsulation layer 50, which is located between the light-emitting layer and the touch layer 40. The encapsulation layer 50 includes a first encapsulation layer 51 and a second encapsulation layer 52 stacked together. The first encapsulation layer includes a plurality of first encapsulation portions 511 disposed in the isolation opening 21. The second encapsulation layer 52 includes a plurality of second encapsulation portions 521 disposed in the through hole 22 and a second encapsulation body 522 located between the first encapsulation layer 51 and the touch layer 40.

[0303] The encapsulation layer is located between the light-emitting layer and the touch layer 40, specifically on the light-emitting side of the light-emitting unit 30. The first encapsulation layer 51 provides encapsulation and protection for the light-emitting unit. Due to the presence of the isolation structure 20, the first encapsulation layer 51 can contain multiple first encapsulation portions 511 corresponding to the light-emitting unit 30 and located within the isolation opening 21. Each first encapsulation portion can independently encapsulate each light-emitting unit 30, thereby improving the encapsulation and protection effect of the light-emitting unit.

[0304] The material composition of the first encapsulation layer 51 is not limited in this embodiment. Exemplarily, the first encapsulation layer 51 includes inorganic materials.

[0305] Each second encapsulation part 521 can be located inside the through hole 22, which can play a filling role, thereby improving the flatness of the display panel.

[0306] In some examples, the encapsulation layer 50 further includes a third encapsulation layer 53 located on the side of the second encapsulation layer 52 opposite to the first encapsulation layer 51. The first encapsulation layer, the second encapsulation layer 52, and the third encapsulation layer can together form a thin-film encapsulation structure, thereby further reducing the risk of water, oxygen, etc., intruding into the light-emitting unit 30 and improving the reliability of the display panel. The material composition of the second encapsulation layer 52 and the third encapsulation layer 53 is not limited in this embodiment. Optionally, both the first encapsulation layer 51 and the third encapsulation layer 53 may include inorganic materials, while the second encapsulation layer 52 may include organic materials. In this way, the first encapsulation layer 51 and the second encapsulation layer 52 can, to a certain extent, limit the second encapsulation layer 50, improving structural reliability.

[0307] Unlike the first encapsulation layer 51, the second encapsulation body 522 and the third encapsulation layer 53 can be a full-surface structure, that is, the orthogonal projection of the second encapsulation body 522 and the third encapsulation layer on the array substrate 10 can simultaneously cover the orthogonal projection of multiple light-emitting units 30 on the array substrate 10.

[0308] Secondly, embodiments of this application also provide a display device, including any of the display panels described above. Since the display device provided in this application includes any of the display panels described above, it possesses the beneficial effects of any of the display panels described above, which will not be elaborated further here.

[0309] The display devices in this application include, but are not limited to, mobile phones, personal digital assistants (PDAs), tablet computers, e-books, televisions, access control systems, smart landline phones, control consoles, and other devices with display functions.

[0310] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
