[0009] In order to improve the manufacturing accuracy of the light-emitting units of the display panel, an isolation structure is usually adopted as an auxiliary structure in the manufacturing process of the light-emitting units, and the isolation structure affects the light-emitting range of the light-emitting units. Especially in the touch display panel, the common influence of the isolation structure and the touch layer will cause differences in the light-emitting ranges of the light-emitting units in different directions, and even cause color shift phenomenon on the display screen.

[0010] International Patent Application No. PCT / CN2023 / 134518 and Chinese Patent Application Nos. 202310771071.0, 202311117143.6, 202310759370.2, 202410008807.3, 202310909421.5, and 202311616249.0 disclose related technical solutions of isolation structure, pixel arrangement, touch, and array, the contents of which are incorporated herein by reference. Therefore, in order to solve the above problems, in a first aspect, an embodiment of the present application provides a display panel.

[0011] 1-3 , an embodiment of the present application provides a display panel including 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, the light-emitting layer includes a plurality of light-emitting units 30, the plurality of light-emitting units 30 include a plurality of light-emitting unit groups E0, each light-emitting unit group E0 emits single color 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, the isolation structure 20 includes isolation openings 21, and the light-emitting units 30 are disposed in the isolation openings 21. The touch layer 40 includes a touch wiring 41, which is disposed on a side of the isolation structure 20 facing away from the array substrate 10, and at least a portion of a orthogonal projection of the touch wiring 41 in the thickness direction Z of the display panel is disposed to surround at least one light-emitting structure and is disposed symmetrically with respect to a first axis of symmetry N1 passing through a centroid of the at least one light-emitting structure, the first axis of symmetry N1 is parallel to a first direction X, and intersects with the first direction X and the thickness direction Z.

[0012] The array substrate 10 plays a supporting role, and the other film layers are sequentially stacked on the array substrate 10, where stacking refers to the other film layers being sequentially disposed along the thickness direction Z of the array substrate 10. The array substrate 10 may include a plurality of film layer structures, and the embodiment of the present application is not limited to the specific film layer structure of the array substrate 10. Note that the thickness direction Z of the other film layers located on one side of the array substrate 10 usually coincides with the thickness direction Z of the array substrate 10 itself, so for convenience of explanation, the thickness direction Z of the array substrate 10 or the thickness direction Z of the other film layers in the following embodiment of the present application are all shown in the same direction.

[0013] The light-emitting layer and the isolation structure 20 are located on the same side of the array substrate 10, and the light-emitting layer includes a plurality of light-emitting units 30, which are main devices for realizing light-emitting display. Here, the light-emitting units 30 include, but are not limited to, a red light-emitting unit that emits red light, a green light-emitting unit that emits green light, and a blue light-emitting unit that emits blue light. Each light-emitting unit 30 may include a hole injection layer (HIL), a hole transport layer (HTL), a light-emitting layer, an electron injection layer (EIL), and an electron transport layer (ETL) that are stacked.

[0014] The light-emitting unit 30 includes a plurality of light-emitting unit groups E0, and the number of light-emitting structures included in each light-emitting unit group E0 may be the same or different.

[0015] Exemplarily, each light emitting unit group E0 includes a plurality of light emitting structures arranged in sequence along the first direction X.

[0016] Adjacent light emitting unit groups E0 may emit the same color light, or of course, may emit different color lights.

[0017] In some examples, the light emitting structures in the light emitting unit groups E0 may be alternately arranged along the first direction X. For example, the light emitting structures in the light emitting unit group E0 emitting red light and the light emitting structures in the light emitting unit group E0 emitting blue light are alternately arranged along the first direction X. In other examples, the light emitting unit groups E0 are sequentially arranged along a single direction or multiple directions.

[0018] The isolation opening 21 surrounded by the isolation structure 20 can accommodate the light-emitting unit 30, i.e., the orthogonal projection of the light-emitting unit 30 on the array substrate 10 at least partially overlaps with the orthogonal projection of the isolation opening 21 on the array substrate 10, and the orthogonal projection of the light-emitting unit 30 on the array substrate 10 is at least partially located within the orthogonal projection of the isolation opening 21 on the array substrate 10. Furthermore, during the manufacturing process of the light-emitting unit 30, the existence of the isolation structure 20 allows the light-emitting material to be isolated into light-emitting units 30 that are independent of each other by the isolation structure 20, and the fine metal mask deposition process can be omitted.

[0019] For example, taking the red light-emitting unit 30 as an example, before the green light-emitting unit 30, because the fine metal mask is cancelled, the red light-emitting material corresponding to the red light-emitting unit 30 falls into each isolation opening 21 first, and then the red light-emitting material in some of the isolation openings 21 is selectively etched away, and the red light-emitting material in some of the isolation openings 21 is reserved to form the red light-emitting unit 30. Then, the green light-emitting material corresponding to the green light-emitting unit 30 falls into each isolation opening 21, and then the green light-emitting material in some of the isolation openings 21 is selectively etched away, and the green light-emitting material in some of the isolation openings 21 is reserved to form the green light-emitting unit 30.

[0020] In the embodiment of the present application, the material of the isolation structure 20 includes a conductive material such as a metal or alloy, and a through hole 22 is provided between two adjacent isolation structures 20, which can improve the light transmittance of the display panel and meet the use needs of components that need to be light-sensitive.

[0021] Optionally, the shape of the orthogonal projection of the isolation opening 21 in the thickness direction Z includes, but is not limited to, a circle, a square, or a rectangle.

[0022] 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 realize a touch function. The touch wiring 41 is disposed in the display panel, and the touch wiring 41 forms a touch capacitance, and after being electrically connected to the driving chip, the touch wiring 41 and the driving chip exchange function signals through the touch capacitance to realize the touch function.

[0023] In some embodiments, at least a portion of the orthogonal projection of the touch wiring 41 in the thickness direction Z of the display panel is disposed relative to at least one light-emitting structure, i.e., the orthogonal projection of the touch wiring 41 in the thickness direction Z may be disposed surrounding one or more light-emitting structures.

[0024] Exemplarily, when the orthogonal projection of the touch wiring 41 in the thickness direction Z is provided to surround one light-emitting structure, the orthogonal projection of the touch wiring 41 in the thickness direction Z is distributed on the periphery of one light-emitting structure, and the touch wiring 41 may have a continuously closed shape or a discontinuous shape. Exemplarily, the figure of the orthogonal projection of the touch wiring 41 in the thickness direction Z includes a circular ring or a semicircular ring.

[0025] For example, when the orthogonal projection of the touch wiring 41 in the thickness direction Z is disposed to surround a plurality of light-emitting structures, the orthogonal projection of the touch wiring 41 in the thickness direction Z may be distributed around the entire plurality of light-emitting structures as a whole within a range recognizable by the human eye. Of course, the touch wiring 41 may be distributed around each light-emitting structure. Alternatively, the number of touch wirings 41 between two adjacent light-emitting structures may be one or two.

[0026] The touch wiring 41 is disposed symmetrically with respect to a first axis of symmetry N1 passing through the centroid of at least one light-emitting structure, i.e., the touch wiring 41 is disposed on both sides of the first axis of symmetry N1, and the first axis of symmetry N1 passes through the light-emitting structure, so that the touch wiring 41 is disposed on both sides of the light-emitting structure that is symmetrical with respect to 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 pass through multiple light-emitting structures. The touch wiring 41 forms a lattice-like touch pattern, the touch pattern includes multiple lattices, one lattice corresponds to at least one light-emitting structure, and at least a portion of the touch pattern surrounding at least one light-emitting structure is disposed symmetrically with respect to the first axis of symmetry N1. The above and following "symmetrical" are both used for a touch pattern surrounding at least one light-emitting structure.

[0027] Optionally, in the thickness direction Z, the orthogonal projection of the touch wiring 41 is arranged to overlap with the orthogonal projection of the isolation structure 20 .

[0028] In the display panel of the present application, the touch wiring 41 is arranged around the isolation opening 21 and is arranged symmetrically with respect to the symmetry axis, so that the touch wiring 41 allows the light-emitting structure to be arranged on both sides of the symmetry axis, and keeps the range of light emitted from the opposite side of the light-emitting structure the same, thereby reducing the difference in the range of light emitted in different directions by the light-emitting units 30 in the isolation opening 21, and further reducing the difference in light emission brightness at different positions of the light-emitting units 30 at a large viewing angle, thereby reducing the possibility of color shift phenomenon occurring on the display screen.

[0029] In some embodiments, referring to FIGS. 1-3, the at least one light emitting structure includes a plurality of light emitting structures, and in the light emitting unit group E0, the plurality of light emitting structures are arranged in sequence along the first direction X.

[0030] For example, one light emitting unit group E0 includes a plurality of light emitting structures, which are arranged in sequence along the first direction X.

[0031] In some embodiments, referring to Figures 1-3, at least a portion of the orthogonal projection of the touch wiring 41 in the thickness direction Z surrounds the multiple light-emitting structures and is arranged symmetrically with respect to a first axis of symmetry N1, which passes through the multiple light-emitting structures.

[0032] In some examples, two adjacent light-emitting structures are both surrounded by touch wiring, and a portion of the touch wiring surrounding one light-emitting structure also surrounds the other light-emitting structure.

[0033] Furthermore, the touch wiring 41 is arranged symmetrically with respect to the first axis of symmetry N1, such that the touch wiring 41 is provided on each of the opposing sides of the light-emitting structure along the second direction Y, and optionally, the second direction Y is arranged to intersect or perpendicularly intersect with the first direction X.

[0034] Alternatively, the first symmetric axis N1 passes through all the light-emitting structures in the light-emitting unit group E0, and of course, the first symmetric axis N1 passes through some of the light-emitting structures in the light-emitting unit group E0.

[0035] In these optional embodiments, the above-mentioned configuration is advantageous in simplifying the layout plan of the touch wiring 41, reducing the difference in viewing angle color shift in the second direction Y of the display panel, and improving the display performance of the display panel.

[0036] In some embodiments, the touch wiring 41 forms a grid-like touch pattern, the touch pattern includes a plurality of grids, each grid corresponds to at least one light-emitting structure, and the portion of the touch pattern surrounding the at least one light-emitting structure is symmetrical about at least a first axis of symmetry.

[0037] In some examples, the arrangement of the plurality of grids is the same as the arrangement of the plurality of isolation openings. In some other examples, one grid may be disposed around the plurality of isolation openings, and one light emitting structure may be disposed in each isolation opening.

[0038] The part of the touch pattern surrounding at least one light-emitting structure is arranged symmetrically with respect to at least a first axis of symmetry, that is, one grid of the touch pattern surrounds one light-emitting unit group, and the touch wiring 41 symmetrical in the second direction is provided around the one light-emitting unit group. Of course, the touch wiring 41 symmetrical in the first direction or other directions may also be provided around the one light-emitting unit group.

[0039] In some optional embodiments, referring to FIGS. 3-5 , in the light-emitting unit group E0, at least one light-emitting structure includes 2N+1 light-emitting structures, and the orthogonal projection of the touch wiring 41 in the thickness direction Z is symmetrically arranged with respect to a second axis of symmetry N2 parallel to the second direction Y, the second axis of symmetry N2 is arranged passing through the centroid of the N+1th light-emitting structure, and N≧0, the second direction Y and the first direction X are all perpendicular to the thickness direction Z.

[0040] Exemplarily, the light emitting unit group E0 includes an odd number of light emitting structures, and the orthogonal projection of the touch wiring 41 in the thickness direction Z is symmetrically arranged with respect to the second symmetry axis N2, so that the touch wiring 41 is provided on both opposing sides of the light emitting structure in the first direction X. Alternatively, in the light emitting unit group E0, the touch wiring 41 is provided on both opposing sides of each light emitting structure in the first direction, or in the light emitting unit group E0, the touch wiring 41 is provided on the side facing away from the jth light emitting structure of the ith light emitting structure, and the touch wiring 41 is provided on the side facing away from the ith light emitting structure of the jth light emitting structure, or in the light emitting unit group E0, the touch wiring 41 is provided on the side facing away from the 2N+1th light emitting structure of the 1st light emitting structure, and the touch wiring 41 is provided on the side facing away from the 2N+1th light emitting structure of the 1st light emitting structure. 1≦i <j≦2N+1。

[0041] Alternatively, the light emitting unit group E0 includes 1, 3, 5, 7 or other odd numbers of light emitting structures.

[0042] In the embodiment of the present application, the above-mentioned arrangement provides touch wiring 41 on both opposing sides of the light-emitting structure in the first direction X, thereby reducing the difference in color shift of the display panel in the first direction X and improving the display performance of the display panel.

[0043] In some optional embodiments, referring to Figures 3 and 4, N = 0, in the light-emitting unit group E0, at least one light-emitting structure includes one light-emitting structure, the orthogonal projection of the touch wiring 41 in the thickness direction Z is symmetrically arranged with respect to a second axis of symmetry N2 parallel to the second direction Y, and the second axis of symmetry N2 is arranged passing through the centroid of the light-emitting structure.

[0044] For example, when the light-emitting unit group E0 includes one light-emitting structure, the light-emitting structure is provided with touch wiring 41 on both sides in the first direction X, and based on this, the light-emitting structure is provided with touch wiring 41 on both sides in the second direction Y, and the orthogonal projection of the touch wiring 41 in the thickness direction Z surrounds the light-emitting structure, thereby reducing the difference in viewing angle color shift in the first direction X and the second direction Y of the display panel.

[0045] Alternatively, the touch wiring 41 having the light emitting structures on both sides along the first direction X and the touch wiring 41 having the light emitting structures on both sides along the second direction Y may be connected to each other, and of course, may be disconnected.

[0046] In some optional embodiments, referring to FIG. 3 and FIG. 5 , N=1, and in the light-emitting unit group E0, at least one light-emitting structure includes three light-emitting structures, and the orthogonal projection of the touch wiring 41 in the thickness direction Z is symmetrically disposed with respect to a second axis of symmetry N2, and the second axis of symmetry N2 is disposed passing through the centroid of the second light-emitting structure along the first direction X.

[0047] For example, when the light-emitting unit group E0 includes three light-emitting structures, the three light-emitting structures are provided with touch wiring 41 on both sides in the second direction Y, or the touch wiring 41 is provided only on both sides of the two light-emitting structures located at both ends, which are back-to-back or facing each other. On this basis, the light-emitting structure is provided with touch wiring 41 on both sides in the second direction Y, so that the orthogonal projection of the touch wiring 41 in the thickness direction Z surrounds the light-emitting structure, thereby reducing the difference in viewing angle color shift in the first direction X and the second direction Y of the display panel.

[0048] FIG. 6 is another enlarged schematic structural diagram of Q in FIG.

[0049] In some optional embodiments, referring to FIG. 6 , in the light-emitting unit group E0, at least one light-emitting structure includes 2N light-emitting structures, and the orthogonal projection of the touch wiring 41 in the thickness direction Z is symmetrically arranged with respect to a third symmetry axis N3 parallel to the second direction Y, where the third symmetry axis N3 is located between the Nth light-emitting structure and the N+1th light-emitting structure, N>0, and the second direction Y and the first direction X are all perpendicular to the thickness direction Z.

[0050] Exemplarily, the light emitting unit group E0 includes an even number of light emitting structures, and the orthogonal projection of the touch wiring 41 in the thickness direction Z is symmetrically arranged with respect to the third symmetry axis N3, and the touch wiring 41 is provided on both opposing sides of the light emitting structure in the first direction X. Alternatively, in the light emitting unit group E0, the touch wiring 41 is provided on both opposing sides of each light emitting structure in the first direction X, or in the light emitting unit group E0, the touch wiring 41 is provided on the side facing away from the jth light emitting structure of the ith light emitting structure, and the touch wiring 41 is provided on the side facing away from the ith light emitting structure of the jth light emitting structure, or in the light emitting unit group E0, the touch wiring 41 is provided on the side facing away from the 2Nth light emitting structure of the 1st light emitting structure, and the touch wiring 41 is provided on the side facing away from the 2Nth light emitting structure of the 1st light emitting structure. 1≦i <j≦2N。

[0051] Alternatively, the light emitting unit group E0 includes two, four, six, eight or other even numbers of light emitting structures.

[0052] In the embodiment of the present application, with the above-mentioned installation, the touch wiring 41 is provided on both opposite sides of the light-emitting structure in 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.

[0053] In some optional embodiments, referring to FIG. 6 , N=1, and in the light-emitting unit group E0, at least one light-emitting structure includes two light-emitting structures, and the orthogonal projection of the touch wiring 41 in the thickness direction Z is arranged symmetrically with respect to a third axis of symmetry N3, and the third axis of symmetry N3 is located midway between the first light-emitting structure and the second light-emitting structure.

[0054] For example, when the light-emitting unit group E0 includes two light-emitting structures, the two light-emitting structures are provided with touch wiring 41 on both sides in the second direction Y, or the touch wiring 41 is provided only on both sides of the two light-emitting structures located at both ends, which are back-to-back or facing each other. On this basis, the light-emitting structure is provided with touch wiring 41 on both sides in the second direction Y, so that the orthogonal projection of the touch wiring 41 in the thickness direction Z surrounds the light-emitting structure, thereby reducing the difference in viewing angle color shift in the first direction X and the second direction Y of the display panel.

[0055] In some alternative embodiments, referring to FIG. 7 , at least a portion of the orthogonal projection of the touch wiring 41 in the thickness direction Z is arranged to surround the multiple light-emitting structures and is arranged symmetrically 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 multiple light-emitting structures, the touch wiring 41 is not provided on a side of the light-emitting structure located at one end of the light-emitting unit group E0 along the first direction X away from the light-emitting structure at the other end of the light-emitting unit group E0 along the first direction X, and the touch wiring 41 is not provided on a side of the light-emitting structure located at the other end of the light-emitting unit group E0 along the first direction X away from the light-emitting structure located at one end of the light-emitting unit group E0 along the first direction X.

[0056] For example, the light-emitting unit group E0 includes a plurality of light-emitting structures, each of which is provided with a touch wiring 41 on both sides in the second direction Y, and neither the side of the first light-emitting structure facing the last light-emitting structure nor the side of the last light-emitting structure facing the first light-emitting structure is provided with a touch wiring 41. The light-emitting structure located at one end of the light-emitting unit group E0 in 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 in the first direction X is the last light-emitting structure.

[0057] Optionally, the first direction X and the second direction Y are arranged perpendicular to each other.

[0058] In the embodiment of the present application, the above-mentioned arrangement can reduce the space occupied by the touch line 41 on the touch layer 40, which is beneficial to reduce the light blocking caused by the touch line 41 and improve the display brightness of the display panel.

[0059] In some optional embodiments, referring to FIG. 4 , the orthogonal projection of the touch wiring 41 in the thickness direction Z completely surrounds the isolation opening 21, and is arranged symmetrically with respect to both a first axis of symmetry N1 and a second axis of symmetry N2, the second axis of symmetry N2 being parallel to a second direction Y, and the second direction Y being intersecting with the first direction X.

[0060] For example, a touch wiring 41 is provided around each of the isolating openings 21, and the touch wiring has a continuous closed shape when orthogonally projected in the thickness direction Z. The touch wiring 41 is symmetrically disposed on both sides of the isolating opening 21 in the first direction X and on both sides of the isolating opening 21 in the second direction Y.

[0061] In the embodiment of the present application, the touch line 41 completely surrounds the isolation opening 21, so that the range of light emitted from the light-emitting structure in the isolation opening 21 is consistent with the range affected by the touch line 41 in any direction, thereby reducing the difference in color shift at different viewing angles and further improving the display performance of the display panel.

[0062] In some optional embodiments, referring to Figures 8-10, the isolation structure 20 further includes a through hole 22, and the through hole 22 is provided between at least some of two adjacent isolation openings 21, and the orthogonal projection of the touch wiring 41 in the thickness direction Z is provided to completely surround the through hole 22.

[0063] Alternatively, the orthogonal projection shape of the through hole 22 in the thickness direction Z can follow the orthogonal projection shape of the isolation opening 21 in the thickness direction Z, or of course, can be a different shape, for example, the orthogonal projection shape of the through hole 22 in the thickness direction Z is a rectangle or a square, and the orthogonal projection shape of the isolation opening 21 in the thickness direction Z is an ellipse.

[0064] In some examples, a through hole 22 is provided between each two adjacent isolation openings 21.

Also, the through hole 22 is provided between two adjacent third light emitting structures 33 in the second light emitting row.

[0100] In these optional embodiments, the light emitting structures are arranged in a rectangular shape, and the apex angles of adjacent light emitting structures in the same row are relatively positioned to shorten the pitch of the light emitting structures in the second direction Y, thereby improving the pixel density and the display effect of the display panel.

[0101] In some optional embodiments, referring to Figures 12 and 13, the shape of the touch wiring 41 surrounding the through hole 22 is rectangular, and the apex angle of any of the first light-emitting structure 31, the second light-emitting structure 32 and the third light-emitting structure 33 is located opposite to the opposite side of the touch wiring 41 surrounding the through hole 22.

The apex angle of the second light-emitting structure 32 is provided opposite to the opposite side of the touch wiring 41 surrounding the through-hole 22. The apex angle of the third light-emitting structure 33 is provided opposite to the opposite side of the touch wiring 41 surrounding the through-hole 22.

[0104] In some optional embodiments, referring to Figures 12 and 13, the orthogonal projection of the touch wiring 41 in the thickness direction Z is arranged to surround the peripheral side of the isolation opening 21 and the peripheral side of the through hole 22, and the touch wiring 41 includes a first segment 411 and a second segment 412, and the orthogonal projection of the first segment in the thickness direction Z and the orthogonal projection of the second segment 412 in the thickness direction Z are arranged to jointly surround the through hole 22 between two adjacent isolation openings 21, and the central connecting line of two adjacent light-emitting structures is arranged perpendicular to the first segment 411, and the central connecting line of two adjacent light-emitting structures is arranged parallel to the second segment 412.

[0106] For example, the connection line between the touch wiring 41 of the first segment 411 and the geometric centers of the two adjacent light-emitting structures is vertically arranged, and the connection line between the touch wiring 41 of the second segment 412 and the geometric centers of the two adjacent light-emitting structures is parallel to the touch wiring 41 of the second segment 412. Here, the "two adjacent light-emitting structures" refers to the light-emitting structures adjacent to the first segment 411.

[0107] In some optional embodiments, referring to FIG. 12 and FIG. 13 , the multiple light emitting structures are arranged in columns along a first direction X and in rows along a second direction Y, in which the central connecting lines of two adjacent light emitting structures in the same column are arranged perpendicular to the first segment 411, and the central connecting lines of two adjacent light emitting structures are arranged parallel to the second segment 412, and the central connecting line between one of the first light emitting structure 31 and the second light emitting structure 32 in the first light emitting column and the third light emitting structure 33 in the second light emitting column is arranged perpendicular to the touch wiring 41 between the first light emitting structure 31 or the second light emitting structure 32 and the third light emitting structure 33.

[0108] Alternatively, in the same row, the central connecting line between two adjacent light emitting structures is a first connecting line L1, the central connecting line between the first light emitting structure 31 in the first light emitting row and the third light emitting structure 33 in the second light emitting row is a second connecting line L2, and the central connecting line between the second light emitting structure 32 in the first light emitting row and the third light emitting structure 33 in the second light emitting row is a third connecting line L3.

[0109] For example, the first connecting line L1 is provided perpendicular to the first segment 411.

[0110] Exemplarily, the second connecting line L2 is disposed perpendicular to the touch wiring 41 between the first light emitting structure 31 and the third light emitting structure 33.

[0111] Exemplarily, the third connecting line L3 is disposed perpendicular to the touch wiring 41 between the second light emitting structure 32 and the third light emitting structure 33.

[0112] In these alternative embodiments, the above-mentioned configuration simplifies the layout manner of the touch wires 41, reduces the difficulty of arranging the touch wires 41, and is favorable for improving the production efficiency of the display panel.

[0113] In some optional embodiments, referring to FIG. 13 , the spacing between one of two adjacent isolation openings 21 and the through hole 22 is equal to the spacing between the other one and the through hole, and the orthogonal projection of the touch wiring 41 in the thickness direction Z is arranged around the peripheral side of the through hole 22.

[0114] For example, a through hole 22 is provided between two adjacent isolated openings 21, the two isolated openings 21 are a first isolated opening 21 and a second isolated opening 21, the distance between the first isolated opening and the through hole 22 is equal to the distance between the second isolated opening 21 and the through hole 22, and the orthogonal projection of the touch wiring 41 in the thickness direction Z is arranged around the peripheral side of the through hole 22, so as to reduce the influence of the touch wiring 41 on the light transmission performance of the through hole 22 and at the same time improve the difference in color shift at different viewing angles of different isolated openings 21.

[0115] In some optional embodiments, referring to Figures 3 and 4, the isolation structure 20 includes a first isolation portion 23 and a second isolation portion 24 located on a side of the first isolation portion away from the substrate, the second isolation portion 21 surrounds and forms an isolation sub-opening 211, the first light emitting structure 31 and the second light emitting structure 32 are adjacent to each other, the orthogonal projection of the touch wiring 41 in the thickness direction Z is located between the adjacent first light emitting structure 31 and second light emitting structure 32, and the distance between the orthogonal projection in the thickness direction Z of the inner wall of the isolation sub-opening 211 on a side closer to the second light emitting structure 32 of the first light emitting structure 31 and the touch wiring 41 is equal to the distance between the orthogonal projection in the thickness direction Z of the inner wall of the isolation sub-opening 211 on a side closer to the first light emitting structure 31 of the second light emitting structure 32 and the touch wiring 41.

[0116] For example, the first isolation portion 23 and the second isolation portion 24 together surround and form the isolation opening 21 , and the second isolation portion 24 surrounds and forms the isolation sub-opening 211 .

[0117] An inner wall of the isolated sub-opening 211 on the side closer to the second light-emitting structure 32 of the first light-emitting structure 31 is a side wall on the side closer to the second light-emitting structure 32 in the second isolated portion 24 of the first light-emitting structure 31, and optionally, this side wall may be a first side wall. An inner wall of the isolated sub-opening 211 on the side closer to the first light-emitting structure 31 of the second light-emitting structure 32 is a side wall on the side closer to the first light-emitting structure 31 in the second isolated portion 24 of the second light-emitting structure 32, and optionally, this side wall may be a second side wall. The distance between the orthogonal projections of the first side wall and the touch wiring 41 in the thickness direction Z is equal to the distance between the orthogonal projections of the second side wall and the touch wiring 41 in the thickness direction Z, thereby reducing the number of touch wirings 41 arranged between two adjacent light-emitting structures, and reducing the influence of the touch wiring 41 on the light-emitting structures.

[0118] In some optional embodiments, referring to Figures 14 and 15, the touch wiring 41 includes a touch conductive portion 42 and a virtual conductive portion 43, and the multiple touch conductive portions are electrically connected to each other to form a touch electrode 44, and the virtual conductive portion 43 is spaced apart from the touch conductive portion 42.

[0120] In some embodiments, the virtual conductive portion 43 may be provided in the touch electrode 44, that is, the virtual conductive portion 43 may be provided in the sensing electrode, and the virtual conductive portion 43 may be provided in the transmitting electrode. By providing the virtual conductive portion 43 in the touch electrode 44, the parasitic capacitance generated by the touch electrode and other conductive film layers can be reduced, so as to reduce the impact of the parasitic capacitance on the touch function; and by providing the virtual conductive portion 43, the difference in the light range emitted by the light-emitting unit 30 at different viewing angles can be reduced, and the possibility of color shift phenomenon occurring on the display screen can be further reduced.

[0121] In some optional embodiments, referring to FIG. 15 , the touch conductive portion 42 includes a first sub-portion 421 and a second sub-portion 422, where the first sub-portion is located on at least one side of the isolation opening 21, and in the thickness direction Z, the orthogonal projection of the second sub-portion 422 surrounds the orthogonal projection of the through hole 22 and is connected to the first sub-portion 421.

[0122] Optionally, the second sub-portions 422 of two adjacent through-holes 22 may be connected via the first sub-portion 421 .

[0123] In the thickness direction Z, the orthogonal projection of the first sub-part 421 is located on at least one side of the orthogonal projection of the isolation opening 21. For example, the orthogonal projection of the isolation opening has a circular shape. The first sub-part 421 may be located on one side of the isolation opening 21 in the first direction X, or the first sub-part 421 may be located on one side of the isolation opening 21 in the second direction Y, or the first sub-part 421 may be arranged to surround the isolation opening 21, and the first sub-part shields the light emitted from the light-emitting unit 30 in the isolation opening. The first sub-part 421 may be arranged on the periphery of the isolation opening 21 according to design requirements, so as to realize the range of light emitted by the light-emitting unit 30 to meet different design needs.

[0124] In the thickness direction Z, the orthogonal projection of the second sub-part 422 is arranged to surround the orthogonal projection of the through hole 22, thereby reducing the possibility that the second sub-part 422 blocks the through hole 22 and further improving the light transmittance of the through hole. The first sub-part 421 and the second sub-part 422 are connected to each other, thereby improving the effective area of ​​the touch electrode 44 formed in the touch conductive part 42, and thereby improving the touch sensitivity.

[0125] In some embodiments, referring to Figures 14 and 15, in the thickness direction Z, the orthogonal projection of the first sub-portion 421 and the orthogonal projection of the second sub-portion 422 are arranged to jointly surround the orthogonal projection of the isolation opening 21.

[0126] In the embodiment of the present application, the second sub-part 422 not only surrounds the through hole 22, but also at least a part of the second sub-part is located between the through hole 22 and the isolation opening 21, and the orthogonal projection of the first sub-part 421 and the orthogonal projection of the second sub-part 422 are arranged to jointly surround the orthogonal 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 at different viewing angles.

[0127] Optionally, the orthogonal projection shape of the second sub-portion 422 may be, but is not limited to, a ring, a semi-ring, or a stripe.

[0128] In some embodiments, referring to Figures 14 and 15, the virtual conductive portion 43 includes a third sub-portion 431 and a fourth sub-portion 432, the fourth sub-portion being arranged surrounding at least one through hole 22, and the third sub-portion 431 being connected to the fourth sub-portion 432 and extending away from the interior of the fourth sub-portion.

[0129] In the embodiment of the present application, the third sub-portion 431 extends away from the interior of the fourth sub-portion 432, i.e., for example, the shape of the orthogonal projection of the fourth sub-portion 432 in the thickness direction Z is a rectangle, the third sub-portion 431 may extend away from the interior of the fourth sub-portion 432 from a side of the rectangle, or the third sub-portion 431 may extend away from the interior of the fourth sub-portion 432 from a corner of the rectangle. Of course, in some other examples, the shape of the orthogonal projection of the fourth sub-portion 432 in the thickness direction Z may further include a circle, a square, a triangle, or other shapes.

[0130] Optionally, the fourth sub-portions 432 of two adjacent through-holes 22 may be connected via the third sub-portion 431 .

[0131] In the thickness direction Z, the orthogonal projection of the third sub-part 431 is located on at least one side of the orthogonal projection of the isolation opening 21. For example, taking the orthogonal projection shape of the isolation opening as a circle, the third sub-part 431 may be located on one side of the isolation opening 21 in the first direction X, or the third sub-part 431 may be located on one side of the isolation opening 21 in the second direction Y, or the third sub-part 431 may be arranged to surround the isolation opening 21, and the third sub-part shields the light emitted from the light-emitting unit 30 in the isolation opening. The third sub-part 431 may be arranged on the periphery of the isolation opening 21 according to design requirements, so as to realize the range of light emitted by the light-emitting unit 30 to meet different design needs.

[0132] In the thickness direction Z, the orthogonal projection of the fourth sub-part 432 is arranged to surround the orthogonal projection of the through hole 22, thereby reducing the possibility that the fourth sub-part 432 blocks the through hole 22 and improving the light transmittance of the through hole.

[0133] In some embodiments, referring to FIG. 15, the fourth sub-portion 432 is provided connected to a plurality of spaced apart third sub-portions 431 .

[0134] Selectively, the multiple third sub-portions 431 connected to the fourth sub-portion 432 may each be arranged between different isolation openings 21, and of course, at least some of the multiple third sub-portions 431 connected to the fourth sub-portion 432 may be located between the same two adjacent isolation openings 21.

[0135] As an example, a plurality of isolation openings 21 are distributed around the periphery of the through hole 22, and the number of the third sub-parts 431 connected to the fourth sub-part 432 is equal to the number of the isolation openings 21 distributed around the periphery of the through hole 22 surrounded by the fourth sub-part 432.

[0136] In the embodiment of the present application, by providing a plurality of third sub-parts 431 in the fourth sub-part 432, the space occupied by the dummy electrode in the touch electrode 44 can be increased, the possibility of the touch electrode and other conductive film layers forming parasitic capacitance can be further reduced, and the plurality of third sub-parts 431 can effectively balance the differences in the light-emitting ranges emitted by the light-emitting units 30 at different viewing angles.

[0137] In some optional embodiments, referring to FIG. 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, and the orthogonal projection of the first isolation portion 23 on the substrate is located within the orthogonal projection of the second isolation portion 24 on the substrate.

[0138] Optionally, the orthogonal projection of the touch wiring 41 in the thickness direction Z and the orthogonal projection of the second isolation portion 24 in the thickness direction Z are provided to at least partially overlap each other.

[0139] The light emitting unit 30 and the first electrode 60 may be formed in the isolation opening 21, the first electrode being located on the side of the light emitting unit 30 facing away from the array substrate 10, the first electrode 60 may be electrically connected to the isolation structure 20, and the first electrode 60 may realize signal exchange between the isolation structure 20 and the driving chip. Optionally, the first electrode 60 includes a cathode.

[0140] The specific dimensions and shapes of the first isolation portion 23 and the second isolation portion 24 are not limited in the embodiments of the present application. For example, the vertical section of the isolation structure 20 may be larger at the top and smaller at the bottom. This design helps prevent the luminescent 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 manufacturing process of the light emitting unit 30 and the first electrode 60, thereby realizing the manufacture and mutual separation of the light emitting units 30 and the first electrodes 60 in different isolation openings 21 without the need for fine metal masks.

[0141] Regarding the material components in the first isolation portion 23 and the second isolation portion 24, the embodiments of the present application are not limited thereto, and the first isolation portion 23 and the second isolation portion 24 may both include a conductive material, or the first isolation portion 23 may include a conductive material and the second isolation portion 24 may include an insulating material, as long as the two electrodes can realize signal transmission through the isolation structure 20.

[0142] In some embodiments, referring to FIG. 16, the isolation structure 20 further includes a third isolation portion 25, and the first isolation portion 23 is located between the third isolation portion and the second isolation portion 24.

[0143] The isolation structure 20 includes at least a first isolation portion 23, a second isolation portion 24, and a third isolation portion 25, and the embodiment of the present application does not limit the dimensions and shapes of the first isolation portion 23, the second isolation portion 24, and the third isolation portion 25. Exemplarily, the orthogonal projection of the first isolation portion 23 on the array substrate 10 is located within the orthogonal projection of the third isolation portion 25 on the array substrate, that is, the vertical cross-sectional shapes of the first isolation portion 23, the second isolation portion 24, and the third isolation portion 25 are U-shaped.

[0144] The third isolation portion 25 also includes a conductive material, similar to the first isolation portion 23, and the first electrode 60 can be in direct contact with the third isolation portion 25 to realize an electrical connection with the first isolation portion 23 through the third isolation portion. Optionally, the first electrode 60 is provided in an overlapping connection with the third isolation portion 25. In addition, the first electrode 60 may be partially located on the side of the third isolation portion 25 away from the array substrate 10, and the provision 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 an aluminum material, the second isolation portion 24 is a titanium material, and the third isolation portion 25 is a molybdenum material.

[0145] In some embodiments, referring to FIG. 16 , the display panel further includes a pixel definition layer 70, which is provided on the array substrate 10, and which includes a pixel limiting portion 71 and a pixel opening 72 defined by the pixel limiting portion, which penetrates the isolation opening 21 to accommodate the light-emitting unit 30, and the orthogonal projection of the inner wall of each pixel opening 72 on the substrate is located within the orthogonal projection of the inner wall of each isolation opening 21 on the array substrate 10.

[0146] The pixel definition layer 70 includes a pixel limiting portion 71 and a pixel opening 72, and the pixel opening is arranged corresponding to the isolation opening 21. For example, the orthogonal projection of the pixel opening 72 on the array substrate 10 may be located within the orthogonal projection of the isolation opening 21 on the array substrate 10, and partial structures in the light-emitting unit 30 and the first electrode 60 may be located within the pixel opening 72.

[0147] In some embodiments, referring to Figures 16 and 17, the isolation structure 20 is provided 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 containment tank 711 and the isolation structure 20 is provided in the containment tank.

[0148] The isolation structure is provided on the side of the pixel limiting portion 71 away from the array substrate 10, i.e., the orthogonal projection of the isolation structure 20 on the array substrate is within the orthogonal projection of the pixel limiting portion 71 on the array substrate 10, thereby improving the blocking effect of the isolation opening 21 formed by being surrounded by the isolation structure 20.

[0149] The pixel limiting portion 71 is provided with an accommodating tank 711, and the accommodating tank may be formed to be recessed by the pixel limiting portion 71 on the side facing away from the array substrate 10. Alternatively, the recess depth of the accommodating tank 711 and the recess depth of the pixel opening 72 may be the same or different. Alternatively, the accommodating tank 711 may be provided penetrating the pixel limiting portion 71.

[0150] Optionally, the through hole 22 and the receiving tank 711 are provided so as to penetrate through the container.

[0151] Optionally, one or more containing grooves 711 may be provided between two adjacent pixel openings 72. The isolation structure 20 is disposed in the containing groove, and the isolation structure occupies a space in the thickness direction Z of the display panel, thereby reducing the overall thickness of the display panel.

[0152] 18 , in some embodiments, the through hole 22 is provided through the first isolation portion 23 and the second isolation portion 24, and divides both the first isolation portion and the second isolation portion into two parts, and the length of the second isolation portion 24 in each part in a direction toward the isolation opening 21 is greater than the length of the first isolation portion 23 in a direction toward the isolation opening 21. Optionally, the side of the second isolation portion 24 and the first isolation portion 23 in each part facing the through hole 22 may be flush, that is, the inner wall surrounding and forming the through hole 22 is a flat surface, thereby reducing the possibility that the through hole is blocked by the isolation structure 20.

[0153] In some embodiments, referring to FIG. 19, a first isolation portion 23 and a second isolation portion 24 arranged in a stack of two or more are provided between adjacent isolation openings 21, and a through hole 22 is provided between the first isolation portion 23 and the second isolation portion 24 arranged in a stack of two or more.

[0154] In the embodiment of the present application, both sides of the through hole may be a first isolation portion 23 and a second isolation portion 24, both of which have a longitudinal section that is larger at the top and smaller at the bottom. Such a design makes it difficult for the luminescent material and electrode material to be connected in the through hole 22 during the manufacturing process of the light emitting unit 30 and the first electrode 60, thereby contributing to reducing the possibility that the luminescent material will be lit up in the through hole 22, causing abnormalities in the display effect.

[0155] In some alternative embodiments, the isolation structure 20 is an insulating structure, i.e., the isolation structure 20 may be the pixel defining layer 70, or the isolation structure may be part of the pixel defining layer.

Optionally, the first display area is a photosensitive area A1, and the second display area is a non-photosensitive area A2.

[0157] Optionally, the second display area may be provided to surround at least a portion of the first display area.

[0158] Optionally, a photosensitive element may be provided in the first display area, and for example, an imaging element, a fingerprint identification device or other photosensitive element may be provided in the first display area. External light can be projected onto the photosensitive element through the through hole 22, and the photosensitive element can operate according to the acquired light beam.

[0159] Alternatively, the through-hole 22 may be provided in the first display area, and of course, the through-hole may be provided in the second display area.

[0160] Alternatively, the light emitting unit group E0 may be disposed in the first display area, and of course, the light emitting unit group E0 may be disposed in the second display area.

The touch layer 40 includes a touch wiring 41, the touch wiring is disposed on a side of the isolation structure 20 facing away from the array substrate 10, and in the first display region, the orthogonal projection of the touch wiring 41 in the thickness direction Z of the display panel is disposed around at least the through hole 22. In the second display region, the orthogonal projection of the touch wiring 41 in the thickness direction Z is disposed around the isolation opening 21.

[0162] Alternatively, as described above, when the display panel includes a first display area and a second display area, the orthogonal projection in the thickness direction Z of the touch wiring 41 in the first display area is provided to surround some or all of the through holes 22. The orthogonal projection in the thickness direction Z of the touch wiring 41 in the second display area is provided to surround the periphery of the isolation opening 21.

[0163] The arrangement of the array substrate 10, the light emitting layer, the isolation structure 20 and the touch layer 40 is the same as that described in the above embodiment of the display panel, and thus the description is omitted here.

[0164] In some optional embodiments, referring to FIG. 2 , the multiple light-emitting units 30 include multiple light-emitting unit groups E0, each light-emitting unit group E0 emitting a single color light, the light-emitting unit group includes at least one light-emitting structure arranged along a first direction X, at least a part of the orthogonal projection of the touch wiring 41 in the thickness direction Z of the display panel is provided by the at least one light-emitting structure and is symmetrical with respect to a first axis of symmetry N1 passing through the at least one light-emitting structure, the first axis of symmetry is parallel to the first direction X and intersects with the first direction and the thickness direction Z.

[0165] The manner in which the light emitting unit group E0 and the touch layer 40 are arranged is the same as that described in the above embodiment of the display panel, and therefore the description thereof is omitted here.

[0166] As shown in FIGS. 1-4 , an embodiment of the present application provides a display panel including an array substrate 10, a light-emitting layer, an isolation structure 20 and a touch layer 40.

The isolation structure 20 is located on one side of the array substrate 10, and the isolation structure includes isolation openings 21, and the light-emitting units 30 are disposed in the isolation openings. The touch layer 40 includes a touch wiring 41, and the touch wiring is disposed on a side of the isolation structure 20 facing away from the array substrate 10. The orthogonal projection of the touch wiring 41 in the thickness direction Z of the display panel is set by the orthogonal projection of at least one isolation opening 21 in the thickness direction Z.

[0167] Optionally, as described above, when the display panel includes an isolation opening, the shape of the orthogonal projection of the touch line 41 in the thickness direction Z includes, but is not limited to, a continuous closed shape and a discontinuous shape. Exemplarily, the shape of the orthogonal projection of the touch line 41 in the thickness direction Z includes a circular ring or a semicircular ring. Optionally, the orthogonal projection of the touch line 41 is arranged to overlap with the orthogonal projection of the isolation structure 20 in the thickness direction Z.

[0168] The arrangement of the array substrate 10, the light emitting layer, the isolation structure 20 and the touch layer 40 is the same as that described in the above embodiment of the display panel, and thus the description is omitted here.

[0169] In the display panel and display device of the present application, the touch wiring 41 is arranged to surround the isolation opening 21, thereby reducing the difference in the range of light emitted in different directions by the light-emitting units 30 in the isolation opening, and further reducing the difference in light emission brightness at different positions of the light-emitting units 30 at a large viewing angle, thereby reducing the possibility of color shift phenomenon occurring on the display screen.

[0170] In some embodiments, referring to Figures 14 to 15, the isolation structure 20 further includes a through hole 22 arranged between two adjacent isolation openings 21, and the orthogonal projection in the thickness direction Z of the touch wiring 41 is arranged to surround the orthogonal projection in the thickness direction of at least a portion of the through hole 22.

[0171] Alternatively, the orthogonal projection of the through hole in the thickness direction Z may be similar to the orthogonal projection of the isolation opening 21 in the thickness direction Z, or may of course be a different shape. Below, an example will be given in which the orthogonal projection of the through hole 22 in the thickness direction Z is a rectangle or square, and the orthogonal projection of the isolation opening 21 in the thickness direction Z is a circle.

[0172] In the embodiment of the present application, the through holes 22 are provided to improve the light transmittance of the display panel, and the touch wiring 41 is arranged to surround at least a portion of the through holes 22, thereby reducing the effect of the touch wiring on the light transmittance.

[0173] In some alternative embodiments, four adjacent through holes 22 are provided surrounding one isolation opening 21 .

[0174] Exemplarily, the isolation opening 21 has two through holes 22 along each of both sides in the first direction X, and the isolation opening has two through holes 22 along each of both sides in the second direction Y.

[0175] In some optional embodiments, four adjacent isolation openings 21 are provided surrounding one through hole 22 .

[0176] Exemplarily, the through hole 22 has two isolating openings 21 along each side in the first direction X, and the through hole has two isolating openings 21 along each side in the second direction Y.

[0177] In some embodiments, referring to FIG. 15 , the display panel further includes a pixel group, which includes a plurality of light-emitting units 30 of different colors and a plurality of through holes 22 distributed around the light-emitting units, and in the pixel group, the plurality of through holes 22 include a first through hole 221 and a second through hole 222, and along the thickness direction Z, the orthogonal projection of the touch conductive portion 42 is arranged to surround the peripheral side of the orthogonal projection of the first through hole 221, and the orthogonal projection of the virtual conductive portion 43 is arranged to surround the peripheral side of the orthogonal projection of the second through hole 222.

[0178] Alternatively, the light emitting units 30 in the display panel may be arranged as pixel groups. Exemplarily, the pixel groups include a plurality of light emitting units 30 of different colors, and the display panel is arranged in a matrix with the pixel groups as basic units. Each pixel group may be provided with a plurality of through holes 22 located between two adjacent light emitting units 30.

[0179] Optionally, a pixel group may include one or more pixel units.

[0180] Alternatively, the number of the first through holes 221 and the number of the second through holes 222 may be the same, or of course, may be different.

[0181] In the embodiment of the present application, by providing a virtual conductive portion 43 in each pixel group, 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 at different viewing angles are balanced.

[0182] In some embodiments, referring to FIG. 15 , the plurality of 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 the first light emitting structures 31 and the second light emitting structures 32 arranged alternately on opposite sides in a first direction X, the second through holes 222 are located between two adjacent third light emitting structures 33, and the first direction X is arranged to intersect with the thickness direction Z.

[0186] The second through hole 222 may be located between two adjacent light emitting units 30, that is, the second through hole 222 may be located at the center of the pixel group. In some examples, the orthogonal projection of one touch electrode 44 in the thickness direction Z covers the orthogonal projection of multiple pixel groups in the thickness direction Z, and by placing the second through hole 222 at the center of the pixel group, the interference of the virtual conductive portion 43 with the touch capacitance formed between the two touch electrodes 44 can be reduced.

[0187] In some embodiments, referring to FIG. 19 , the display panel further includes a sealing layer 50 located between the light-emitting layer and the touch layer 40, and the sealing layer 50 includes a first sealing layer 51 and a second sealing layer 52 arranged in a stacked manner, the first sealing layer includes a plurality of first sealing portions 511 distributed within the isolation opening 21, and the second sealing layer 52 includes a plurality of second sealing portions 521 provided in the through hole 22 and a second sealing body 522 located between the first sealing layer 51 and the touch layer 40.

The first encapsulation layer 51 may serve to encapsulate and protect the light-emitting unit. Due to the presence of the isolation structure 20, the manufactured first encapsulation layer 51 may have a plurality of first encapsulation parts 511 corresponding to the light-emitting units 30 and located in the isolation openings 21, and each first encapsulation part functions as an independent encapsulation for each light-emitting unit 30, thereby improving the encapsulation and protection effect for the light-emitting unit.

[0190] Each second sealing portion 521 may be located within the through-hole 22, which can fulfill a filling function and subsequently improve the flatness of the display panel.

[0191] In some examples, the encapsulation layer 50 further includes a third encapsulation layer 53 located on the side of the second encapsulation layer 52 facing the first encapsulation layer 51, and the first encapsulation layer, the second encapsulation layer 52, and the third encapsulation layer can jointly form a thin film encapsulation structure, which further reduces the risk of water, oxygen, etc. penetrating into the light emitting unit 30, and improves the reliability of the display panel. The material components of the second encapsulation layer 52 and the third encapsulation layer 53 are not limited in the embodiments of the present application. Alternatively, the first encapsulation layer 51 and the third encapsulation layer 53 both include inorganic materials, and the second encapsulation layer 52 includes organic materials, so that the first encapsulation layer 51 and the second encapsulation layer 52 can play a positional limiting role on the second encapsulation layer 50 to a certain extent, and can improve the reliability of the structure.

[0192] Unlike the first sealing layer 51, the second sealing body 522 and the third sealing layer 53 may be a full-surface structure, that is, the orthogonal projection of the second sealing body 522 and the third sealing layer on the array substrate 10 can simultaneously cover the orthogonal projection of multiple light-emitting units 30 on the array substrate 10.
