[0110] In the related art, in order to improve the preparation accuracy of the light-emitting unit of the display panel, an isolation structure is usually used as an auxiliary structure in the preparation process of the light-emitting unit, and the isolation structure will affect the light-emitting range of the light-emitting unit. Especially in the touch display panel, under the joint influence of the isolation structure and the touch layer, the light-emitting range of the light-emitting unit in different directions will be differentiated, which will cause color deviation in the display screen.

Therefore, in order to solve the above problems, in the first aspect, an embodiment of the present invention proposes a display panel and a display device.

[0112] Figure 1 It is a schematic diagram of a top view structure of a display panel provided in an embodiment of the present application. Figure 2 yes Figure 1 Schematic diagram of an amplified structure of Q. Figure 3 It is a schematic diagram of the cross-sectional structure of a display panel provided in an embodiment of the present application.

[0113] like Figures 1 to 3 As shown, an embodiment of the present application 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 the light-emitting layer includes a plurality of light-emitting units 30, and the plurality of light-emitting units 30 include 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 arranged along a first direction X. The isolation structure 20 is located on one side of the array substrate 10, and the isolation structure 20 includes an isolation opening 21, and the light-emitting unit 30 is arranged in the isolation opening 21. The touch layer 40 includes a touch trace 41, and the touch trace 41 is arranged on the side of the isolation structure 20 that is not facing the array substrate 10, and at least part of the orthographic projection of the touch trace 41 in the thickness direction Z of the display panel is arranged around at least one light-emitting structure, and is symmetrically arranged relative to a first symmetry axis N1 passing through the centroid of at least one light-emitting structure, and the first symmetry axis N1 is parallel to the first direction X, and the first direction X and the thickness direction Z are arranged to intersect.

[0114] The array substrate 10 can play a supporting role, and other film layers are stacked on the array substrate 10 in sequence. The stacking arrangement mentioned here means that the other film layers are sequentially arranged along the thickness direction Z of the array substrate 10. Among them, the array substrate 10 may include multiple film layer structures, and the specific film layer structure composition of the array substrate 10 is not limited in the embodiment of the present application. And the thickness direction Z of other film layers located on one side of the array substrate 10 is usually consistent with the thickness direction Z of the array substrate 10 itself. Therefore, for the convenience of expression, the thickness direction Z of the array substrate 10 or the thickness direction Z of other film layers mentioned later in the embodiment of the present application are all illustrated 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 a plurality of light-emitting units 30, which are the main devices for realizing light-emitting display. Among them, 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 (HOL), 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 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 may be different.

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

[0118] Adjacent light emitting unit groups E0 may emit light of the same color, or of course, may also emit light of different colors.

[0119] In some examples, the light emitting structures in the plurality of light emitting unit groups E0 may be alternately arranged along the first direction X. For example, the plurality of light emitting structures in the light emitting unit group E0 emitting red light and the plurality of 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 plurality of light emitting unit groups E0 are sequentially arranged 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 is at least partially overlapped with the orthographic projection of the isolation opening 21 on the array substrate 10, 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. Further, during the preparation of the light-emitting unit 30, due to the existence of the isolation structure 20, the light-emitting material can be separated into mutually independent light-emitting units 30 by the isolation structure 20, and the precision metal mask evaporation process can be omitted.

[0121] For example, taking the preparation of the red light-emitting unit 30 before the preparation of the green light-emitting unit 30 as an example, since the precision metal mask is eliminated, the red light-emitting material corresponding to the red light-emitting unit 30 will first fall into each isolation opening 21, and then the red light-emitting material in a part of the isolation opening 21 will be selectively etched away, and the red light-emitting material in a part of the isolation opening 21 will be retained to form the red light-emitting unit 30. After that, the green light-emitting material corresponding to the green light-emitting unit 30 will fall into each isolation opening 21, and then the green light-emitting material in a part of the isolation opening 21 will be selectively etched away, and the green light-emitting material in a part of the isolation opening 21 will be retained to form the green light-emitting unit 30.

[0122] In the embodiment of the present application, the material of the isolation structure 20 includes a conductive material such as a metal or an alloy, and the through hole 22 is arranged between two adjacent isolation structures 20. The through hole 22 can improve the light transmittance of the display panel to meet the use requirements of devices that require photosensitivity.

[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 arranged on the side of the light emitting layer away from the array substrate 10, and the touch layer 40 can be used to realize the touch function. The touch wiring 41 is arranged in the display panel, and the touch wiring 41 is used to form a touch capacitor. After being electrically connected to the driving chip, the touch wiring 41 and the driving chip exchange functional signals through the touch capacitor to realize the touch function.

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

[0126] Exemplarily, when the orthographic projection of the touch line 41 along the thickness direction Z is arranged around a light-emitting structure, the orthographic projection of the touch line 41 along the thickness direction Z is distributed around a light-emitting structure, and the touch line 41 can be a continuous closed shape or a discontinuous shape. Exemplarily, the orthographic projection figure of the touch line 41 along the thickness direction Z includes a circular ring or a semicircular ring.

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

[0128] The touch trace 41 is symmetrically arranged with respect to a first symmetry axis N1 passing through the centroid of at least one light-emitting structure. In other words, the touch trace 41 is arranged on both sides of the first symmetry axis N1, and because the first symmetry axis N1 passes through the light-emitting structure, the touch trace 41 is arranged on both sides of the light-emitting structure symmetrically with respect to the first symmetry axis N1. Optionally, the centroid includes a geometric center. Optionally, the first symmetry axis N1 may pass through the geometric center of the light-emitting structure. Optionally, the first symmetry axis N1 may pass through one light-emitting structure, and of course, may also pass through multiple light-emitting structures. The touch trace 41 forms a grid-shaped touch pattern, the touch pattern includes multiple grids, one grid corresponds to at least one light-emitting structure, and the portion of the touch pattern surrounding at least one light-emitting structure is symmetrically arranged at least with respect to the first symmetry axis N1. The "symmetry" mentioned above and in the following text 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 and the orthographic projection of the isolation structure 20 are overlapped.

[0130] In the display panel provided in the present application, the touch wiring 41 is arranged around the isolation opening 21 and symmetrically arranged relative to the symmetry axis, so that the touch wiring 41 is arranged on both sides of the light-emitting structure relative to the symmetry axis, so that the range of light emitted from the opposite sides of the light-emitting structure remains the same, thereby reducing the difference in the range of light emitted in different directions by the light-emitting unit 30 in the isolation opening 21, and further reducing the difference in the light-emitting brightness at different positions of the light-emitting unit 30 under a wide viewing angle, thereby reducing the possibility of color cast in the display screen.

[0131] In some embodiments, see Figures 1 to 3 , at least one light emitting structure includes a plurality of light emitting structures, and within the light emitting unit group E0, the plurality of light emitting structures are sequentially arranged along the first direction X.

[0132] Exemplarily, one light emitting unit group E0 includes a plurality of light emitting structures, and the plurality of light emitting structures are sequentially arranged along the first direction X.

[0133] In some embodiments, see Figures 1 to 3 At least part of the orthographic projection of the touch wiring 41 in the thickness direction Z is arranged around the multiple light-emitting structures, and is symmetrically arranged relative to the first symmetry axis N1, and the first symmetry axis N1 passes through the multiple light-emitting structures.

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

[0135] Further, the touch lines 41 are symmetrically arranged with respect to the first symmetry axis N1, so that the touch lines 41 are arranged on opposite sides of the light emitting structure along the second direction Y. Optionally, the second direction Y and the first direction X intersect or are arranged perpendicularly.

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

[0137] In these optional embodiments, the above configuration is helpful to simplify the layout of the touch wiring 41, reduce the color deviation difference of the viewing angle of the display panel in the second direction Y, and improve the display performance of the display panel.

[0138] In some embodiments, the touch traces 41 form a grid-like touch pattern, the touch pattern includes a plurality of grids, one grid corresponds to at least one light-emitting structure, and a portion of the touch pattern surrounding the at least one light-emitting structure is symmetrically arranged at least relative to the first symmetry axis.

[0139] In some examples, the arrangement of the plurality of grids is the same as the arrangement of the plurality of isolation openings. In other examples, a grid is arranged around a plurality of isolation openings, and a light emitting structure may be arranged in each isolation opening.

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

Optionally, in the light-emitting unit group E0, each light-emitting structure is provided with a touch wiring 41 on both sides of the light-emitting structure that are opposite to each other along the first direction; or, in the light-emitting unit group E0, a touch wiring 41 is arranged on the side of the i-th light-emitting structure facing away from the j-th light-emitting structure, and a touch wiring 41 is arranged on the side of the j-th light-emitting structure facing away from the i-th light-emitting structure; or, in the light-emitting unit group E0, a touch wiring 41 is arranged on the side of the first light-emitting structure facing away from the 2N+1-th light-emitting structure, and a touch wiring 41 is arranged on the side of the 2N+1-th light-emitting structure facing away from the first light-emitting structure. 1≤i<j≤2N+1.

On this basis, touch lines 41 are provided on both sides of the light-emitting structure along the second direction Y, so that the orthographic projection of the touch lines 41 in the thickness direction Z surrounds the circumference of the light-emitting structure, thereby reducing the difference in viewing angle angular deviation of the display panel in the first direction X and the second direction Y.

[0148] Optionally, the touch lines 41 disposed on both sides of the light emitting structure along the first direction X and the touch lines 41 disposed on both sides of the light emitting structure along the second direction Y may be connected to each other, or may be disconnected.

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

[0155] In the embodiment of the present application, through the above configuration, touch lines 41 are provided on both opposite sides of the light emitting structure along the first direction X, thereby reducing the color cast difference of the display panel in the first direction X and improving the display performance of the display panel.

[0159] In some optional embodiments, see Figure 7 At least part of the orthographic projection of the touch wiring 41 in the thickness direction Z is arranged around the multiple light-emitting structures, and is symmetrically arranged relative to a first symmetry axis N1 parallel to the first direction X, the first symmetry axis N1 passes through the centroids of the multiple light-emitting structures, and the light-emitting structure located at one end of the light-emitting unit group E0 along the first direction X in the light-emitting unit group E0 is not provided with a touch wiring 41 on a side away from the light-emitting structure at the other end of the light-emitting unit group E0 along the first direction X, and the light-emitting structure located at the other end of the light-emitting unit group E0 along the first direction X in the light-emitting unit group E0 is not provided with a touch wiring 41 on a side away from the light-emitting structure at one end of the light-emitting unit group E0 along the first direction X.

[0160] Exemplarily, the light-emitting unit group E0 includes a plurality of light-emitting structures, each light-emitting structure is provided with touch wiring 41 on both sides along the second direction Y, and in the light-emitting unit group E0, the side of the first light-emitting structure facing away from the last light-emitting structure and the side of the last light-emitting structure facing away from the first light-emitting structure are not provided with touch wiring 41. The light-emitting structure in the light-emitting unit group E0 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 in the light-emitting unit group E0 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 arranged perpendicularly.

[0162] In the embodiment of the present application, the above configuration is helpful to reduce the space occupied by the touch wiring 41 in the touch layer 40, thereby reducing the shielding of light by the touch wiring 41 and improving the display brightness of the display panel.

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

[0171] In the embodiment of the present application, the light transmittance of the display panel is improved by setting a through hole 22, and the touch line 41 is completely surrounded by the through hole 22, which is beneficial to reduce the possibility of the touch line 41 blocking the through hole 22 from the front, and reduce the difference in light intensity received by the photosensitive device through the through hole 22 at different viewing angles.

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 to 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 to each other in the second direction Y. The "relative arrangement" here can be 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 correspondingly located between the adjacent first light emitting structure 31 and the second light emitting structure 32 in the first light emitting column.

By arranging 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, thereby reducing the influence of the parasitic capacitance on the touch function. In addition, setting the virtual conductive portion 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 deviation in the display screen.

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

[0233] In the thickness direction Z, the orthographic projection of the first sub-portion 421 is located on at least one side of the orthographic projection of the isolation opening 21.

[0237] Optionally, the orthographic projection shape of the second sub-portion 422 may be, but is not limited to, a ring shape, a semi-ring shape, or a strip shape.

[0238] In some embodiments, see Fig.14 and Fig.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 , and the third sub-portion 431 is connected to the fourth sub-portion 432 and extends away from the interior of the fourth sub-portion.

[0239] In the embodiment of the present application, the third sub-portion 431 is arranged along the inner part away from the fourth sub-portion 432. In other words, taking the orthographic projection shape of the fourth sub-portion 432 along the thickness direction Z as a rectangle as an example, the third sub-portion 431 can be arranged along the side edge of the rectangle and extend away from the inner part of the fourth sub-portion 432, and the third sub-portion 431 can be arranged along the corner of the rectangle and extend away from the inner part of the fourth sub-portion 432.

[0240] Optionally, the fourth sub-portions 432 of two adjacent through holes 22 may be connected via the third sub-portion 431 .

[0241] In the thickness direction Z, the orthographic projection of the third sub-portion 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-portion 431 can be located on one side of the isolation opening 21 along the first direction X, or the third sub-portion 431 can be located on one side of the isolation opening 21 along the second direction Y, or the third sub-portion 431 can be arranged around the isolation opening 21.

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

For example, the longitudinal section of the isolation structure 20 can be larger at the top and smaller at the bottom. This design helps in the preparation process of the light-emitting unit 30 and the first electrode 60, making it difficult for the light-emitting material and the electrode material to extend along the side wall of the first isolation portion 23 to the side wall of the second isolation portion 24, thereby realizing the preparation and mutual separation of the light-emitting unit 30 and the first electrode 60 in different isolation openings 21 without the need for a fine metal mask.

[0259] In some embodiments, see Fig.16 and Fig.17 The isolation structure 20 is disposed on a side of the pixel defining portion 71 away from the array substrate 10 , or a receiving groove 711 is disposed on the pixel defining portion 71 , and the isolation structure 20 is disposed in the receiving groove.

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

[0261] The pixel defining portion 71 is provided with a receiving groove 711, which can be formed by a depression on the side of the pixel defining portion 71 facing away from the array substrate 10.

This design helps in the preparation process of the light-emitting unit 30 and the first electrode 60, making it difficult for the light-emitting material and the electrode material to fall into the through hole 22 and connect together, thereby reducing the possibility of the light-emitting material being lit in the through hole 22 and causing abnormal display effects.

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

[0281] like Figures 1 to 4 As shown, an embodiment of the present application 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 the light-emitting layer includes a plurality of light-emitting units 30. The isolation structure 20 is located on one side of the array substrate 10, and the isolation structure includes an isolation opening 21, and the light-emitting unit 30 is arranged in the isolation opening.

[0282] Optionally, as described above, when the display panel includes an isolation opening, the orthographic projection shape of the touch trace 41 along the thickness direction Z includes, but is not limited to, a continuous closed shape and a discontinuous shape. Exemplarily, the orthographic projection shape of the touch trace 41 along the thickness direction Z includes a circular ring or a semicircular 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 arrangement of the array substrate 10 , the light emitting layer, the isolation structure 20 , and the touch layer 40 is as described in the above display panel embodiment, and will not be repeated here.

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

[0285] In some embodiments, see Figure 14 to Figure 15 The isolation structure 20 further includes a through hole 22 , which is disposed between two adjacent isolation openings 21 , and an orthographic projection of the touch trace 41 in the thickness direction Z surrounds at least a portion of an orthographic projection of the through hole 22 in the thickness direction.

[0286] Optionally, the orthographic projection figure of the through hole along the thickness direction Z can be similar to the orthographic projection figure of the isolation opening 21 along the thickness direction Z. Of course, they can also be different figures. The following example is taken as an example in which the orthographic projection figure of the through hole 22 along the thickness direction Z is a rectangle or a square, and the orthographic projection figure of the isolation opening 21 along the thickness direction Z is a circle.

[0287] In the embodiment of the present application, the light transmittance of the display panel is improved by providing the through hole 22 , and the touch wiring 41 is provided around at least a portion of the through hole 22 to reduce the influence of the touch wiring on the light transmittance.

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

[0289] Exemplarily, two through holes 22 are respectively arranged on both sides of the isolation opening 21 along the first direction X, and two through holes are respectively arranged on both sides of the isolation opening along the second direction Y.

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

[0291] Exemplarily, two isolation openings 21 are respectively arranged on both sides of the through hole 22 along the first direction X, and two isolation openings are respectively arranged on both sides of the through hole along the second direction Y.

[0292] In some embodiments, see Fig.15 The display panel also 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. 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 orthographic projection of the touch conductive portion 42 is arranged around the orthographic projection of the first through hole 221, and the orthographic projection of the virtual conductive portion 43 is arranged around the orthographic projection of the second through hole 222.

[0293] Optionally, the arrangement of the light-emitting units 30 in the display panel can be arranged in the form of pixel groups. Exemplarily, a pixel group includes a plurality of light-emitting units 30 of different colors, and the display panel is arranged in a matrix with the pixel group as a basic unit. A plurality of through holes 22 can be provided in each pixel group, and each through hole is 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 the first through holes 221 and the number of the second through holes 222 may be the same, or may be different.

[0296] In the embodiment of the present application, a virtual conductive portion 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 emitting range of the light emitting unit 30 at different viewing angles.

[0297] In some embodiments, see 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 is provided with first light-emitting structures 31 and second light-emitting structures 32 alternately distributed 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 colors of the first light emitting structure 31 , the second light emitting structure 32 and the third light emitting structure 33 are different.

[0299] Optionally, the pixel group may include two third light emitting structures 33 , one first light emitting structure 31 and one 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, the first light emitting structures 31 and the second light emitting structures 32 are alternately distributed on the first side, and the first light emitting structures 31 and the second light emitting structures 32 are alternately distributed on the second side.

[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 projections of multiple pixel groups along the thickness direction Z. The second through hole 222 is set at the center of the pixel group, which can reduce the interference of the virtual conductive part 43 on the touch capacitance formed between the two touch electrodes 44.

[0302] In some embodiments, see Fig.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 which are stacked. The first encapsulation layer includes a plurality of first encapsulation parts 511 respectively arranged in the isolation opening 21, the second encapsulation layer 52 includes a plurality of second encapsulation parts 521 respectively arranged 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, that is, located on the light-emitting surface side of the light-emitting unit 30. The first encapsulation layer 51 can play a role in encapsulating and protecting the light-emitting unit. Due to the existence of the isolation structure 20, the prepared first encapsulation layer 51 can have multiple first encapsulation parts 511 corresponding to the light-emitting unit 30 and located in the isolation opening 21, and each first encapsulation part can play a role in independently encapsulating each light-emitting unit 30, thereby improving the encapsulation and protection effect of the light-emitting unit.

[0304] The present embodiment does not limit the material composition of the first encapsulation layer 51. Exemplarily, the first encapsulation layer 51 includes an inorganic material.

[0305] Each second packaging portion 521 may be located in the through hole 22 and may play a filling and leveling 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 facing away from the first encapsulation layer 51. The first encapsulation layer, the second encapsulation layer 52, and the third encapsulation layer can form a thin film encapsulation structure together, thereby further reducing the risk of water and oxygen 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 the embodiment of the present application. Optionally, 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 limit the second encapsulation layer 50 to a certain extent, thereby improving the structural reliability.

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