[0076] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present application and are not configured to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

[0077] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0078] It should be understood that when describing the structure of a component, when a layer or a region is referred to as being "on" or "over" another layer or region, it may mean that it is directly on the other layer or region, or that other layers or regions are included between it and the other layer or region. Furthermore, if the component is turned over, the layer or region will be "below" or "beneath" the other layer or region.

[0079] In the related art, a light sensor is provided on one side of a display panel to receive light passing through the display panel. However, the light transmittance of the display panel is poor, which affects the recognition accuracy of the light sensor.

[0080] To solve the above problems, embodiments of the present application provide a display panel and a display device. Various embodiments of the display panel and the display device will be described below with reference to the accompanying drawings.

[0081] In a first aspect, the present application provides a display panel, as shown in Figures 1 and 2, a display panel includes an array substrate 1, an isolation structure 2, a light-emitting functional layer and a touch layer 4, the isolation structure 2 is arranged on one side of the array substrate 1, and a plurality of isolation openings 23 and a plurality of first openings 24 are provided on the isolation structure 2; the light-emitting functional layer includes a plurality of light-emitting units 31, and at least part of the light-emitting units 31 is arranged in the isolation opening 23; the touch layer 4 is arranged on the side of the isolation structure 2 away from the array substrate 1, the touch layer 4 includes a touch trace 41, the orthographic projection of the touch trace 41 on the array substrate 1 is located within the orthographic projection of the isolation structure 2 on the array substrate 1, the orthographic projection of the touch trace 41 on the isolation structure 2 is a first projection, and the first projection surrounds a portion of the boundary of at least one first opening 24.

[0082] The display panel provided in the embodiments of the present application may be a display panel based on organic light emitting diode (OLED) technology. The isolation structure 2 is described in patents PCT / CN2023 / 134518, 202310759370.2, 202310740412.8, 202310707209.0, 202311346196.5, and 202310909421.5 for reference.

[0083] In the display panel provided in the embodiment of the present application, the array substrate 1 can not only provide support for the isolation structure 2, but also provide electrical signals for the light-emitting functional layer and the touch layer 4. There are many ways to set up the array substrate 1. In some embodiments, the array substrate 1 may include a substrate 11 and a driving circuit layer 12 arranged on the substrate 11. The substrate 11 may be a silicon substrate, or a flexible substrate 11 such as polyimide. The driving circuit layer 12 may include a pixel driving circuit, a plurality of conductive connection structures arranged in a stacked manner, a plurality of driving units, and the like. Exemplarily, the pixel driving circuit arranged in the driving circuit layer 12 includes a transistor and a storage capacitor. Exemplarily, each driving unit may include one or more semiconductor switching devices. The semiconductor switching device may be formed by the cooperation of multiple film layers in the array substrate 1. For example, the semiconductor switching device may be a thin film transistor formed by the cooperation of multiple film layers.

[0084] The isolation structure 2 is surrounded by a plurality of isolation openings 23, and a plurality of first openings 24 are provided on the isolation structure 2. The isolation openings 23 are used to limit the light-emitting units 31, and at least part of the light-emitting units 31 are located within the isolation openings 23, that is, the orthographic projections of at least part of the light-emitting units 31 on the array substrate 1 are located within the orthographic projections of the isolation openings 23 on the array substrate 1. The number of isolation openings 23 may correspond one-to-one to the number of light-emitting units 31, or a plurality of light-emitting units 31 may be provided in one isolation opening 23. Light entering the display panel from one side of the display panel may pass through the first openings 24 and be emitted from the other side of the display panel, and a light sensor located on one side of the display panel may receive the light and realize photoelectric conversion. The light sensor may specifically be an infrared sensor, a camera, etc.

[0085] The multiple light-emitting units 31 can each emit light of different colors. For example, they can be red light-emitting units 31 that can emit red light, green light-emitting units 31 that can emit green light, and blue light-emitting units 31 that can emit blue light. The number of isolation openings 23 and first openings 24 can be determined as needed. For example, one red light-emitting unit 31, two green light-emitting units 31, and one blue light-emitting unit 31 can be positioned within four isolation openings 23 to form a pixel light-emitting group 32. The pixel light-emitting groups 32 are arranged in an array along the first direction X and the second direction Y.

[0086] The orthographic projection of the first opening 24 on the array substrate 1 does not overlap with the orthographic projection of the light emitting unit 31 on the array substrate 1. The first opening 24 may be a light-transmitting opening.

[0087] The orthographic projection of the first opening 24 on the array substrate 1 is set to not overlap with the orthographic projection of the light emitting unit 31 on the array substrate 1 , so that external light is not blocked by the light emitting unit 31 , thereby allowing external light to pass through the first opening 24 smoothly.

[0088] The touch layer 4 enables the display device to perform touch operation. The touch layer 4 can be arranged on the light-emitting side of the light-emitting functional layer. In order to avoid the touch layer 4 affecting the display of the light-emitting functional layer, the touch layer 4 can be prepared using a light-transmitting material. The touch layer 4 can be a mesh electrode film based on metal mesh capacitive touch technology (Metal Mesh). The touch layer 4 can include touch lines 41, which are patterned grid lines. The touch lines 41 can include one or more conductive grid lines, and the touch lines 41 can be prepared by exposure etching technology. Multiple touch lines 41 can be connected, and a break that disconnects the grid lines is provided in the touch lines 41. The grid lines on both sides of the break can be used as mutually capacitive drive electrodes and sensing electrodes to collect touch signals. Adjacent touch lines 41 can also be disconnected by the break, so that adjacent touch lines 41 can be used as mutually capacitive drive electrodes and sensing electrodes to collect touch signals. Multiple touch lines 41 are arranged in the display panel so that the display panel can have a touch function.

[0089] The "orthographic projection" described in this application may be a projection along a third direction Z, which may be the thickness direction of the display panel or the direction from the array substrate 1 to the light-emitting functional layer. Alternatively, referring again to Figures 1 and 2 , the orthographic projection of the touch trace 41 on the array substrate 1 does not overlap with the orthographic projection of the isolation opening 23 or the first opening 24 on the array substrate 1.

[0090] If the orthographic projection of the touch trace 41 on the array substrate 1 overlaps with the orthographic projection of the isolation opening 23 on the array substrate 1 , the overlapping portion of the touch trace 41 will block the light emitted by the light emitting unit 31 , thereby affecting the transmittance of the light emitted by the light emitting unit 31 .

[0091] If the orthographic projection of the touch trace 41 on the array substrate 1 overlaps with the orthographic projection of the first opening 24 on the array substrate 1, the overlapping portion of the touch trace 41 will block external light from reaching the components in the first display area AA1, thereby affecting the precision of the components. In addition, there is no isolation structure 2 or the second electrode 35 of the light-emitting unit 3 between the touch trace 41 and the signal trace 121 of the array substrate 1 to shield them. Therefore, the touch trace 41 and the signal trace 121 of the array substrate 1 will interfere with each other, thereby reducing the display quality and touch precision of the display panel.

[0092] In this embodiment, the orthographic projection of the touch trace 41 on the array substrate 1 is set to not overlap with the orthographic projection of the isolation opening 23 and / or the first opening 24 on the array substrate 1, which not only improves the transmittance of the light emitted by the light-emitting unit 31, but also improves the transmittance of the first display area AA1.

[0093] The first projection surrounds a portion of the boundary of at least one first opening 24, so that the first projection is along the first opening 24 and does not surround another portion of the boundary of the first opening 24, thereby increasing the size of the first opening 24 and improving the light transmittance of the display panel. For example, in the embodiment shown in Figure 5, the touch trace 41 does not surround the left boundary of the first opening 24. The first projection of the touch trace 41 surrounds the top, bottom, and right boundaries of the first opening 24, so that the left boundary of the first opening 24 can be shifted to the left or expanded, thereby increasing the size of the first opening 24.

[0094] The display panel provided in the present application may further include a cover plate covering the side of the touch layer 4 facing away from the array substrate 1 , an optical adhesive layer located between the cover plate and the touch layer 4 , an encapsulation layer encapsulating the light-emitting unit 31 , and the like.

[0095] In the embodiment provided in the present application, by setting the first opening 24, the light transmittance of the display panel can be improved; by positioning the orthographic projection of the touch line 41 on the array substrate 1 within the orthographic projection of the isolation structure 2 on the array substrate 1, the touch layer 4 is prevented from or reduced from blocking the light entering the first opening 24 or blocking the light exiting the isolation opening 23, thereby improving the light transmittance of the display panel; by setting the first projection of the touch line 41 to surround a portion of the boundary of at least one first opening 24, it is beneficial to increase the size of the first opening 24 and improve the light transmittance.

[0096] In some embodiments, the first projection of the touch trace 41 does not surround another portion of the boundary of at least one first opening 24 . The first opening 24 is located between adjacent isolation openings 23 , and no first projection is distributed between a portion of the boundary of the first opening 24 and the isolation opening 23 .

[0097] The first opening 24 is located between adjacent isolation openings 23, and the adjacent isolation openings 23 and the first opening 24 are separated by an isolation structure 2. The first opening 24 is provided between adjacent isolation openings 23 so that the partial area can emit light through the light-emitting unit 31 in the isolation opening 23, and can also transmit light from one side of the display panel through the first opening 24. The first projection is not distributed between part of the boundary of the first opening 24 and the isolation opening 23, so that the space reserved for the touch line 41 can be omitted between the first opening 24 and the isolation opening 23, so that there is a smaller distance between the first opening 24 and the isolation opening 23, thereby increasing the size of the first opening 24 and the isolation opening 23, thereby improving the transmittance of the display panel.

[0098] In some embodiments, referring again to Figures 1 and 2 , the orthographic projection of the touch trace 41 on the array substrate 1 is located between the orthographic projections of adjacent light-emitting units 31 on the array substrate 1. Placing the touch trace 41 between adjacent light-emitting units 31 allows the light-emitting units 31 to have a larger viewing angle. Therefore, the touch trace 41 has a relatively small impact on the overall light transmittance and color shift of the display panel.

[0099] In some embodiments, referring to Figures 3 and 4, the orthographic projection shape of the first opening 24 on the array substrate 1 includes a square or a circle. For example, the orthographic projection shape of the first opening 24 on the array substrate 1 as shown in Figure 1 includes a square. The orthographic projection shape of the first opening 24 on the array substrate 1 can also be set to other shapes according to actual conditions, and is not limited to the square or circle proposed in this embodiment.

[0100] Alternatively, referring again to FIG. 3 , the orthographic projection of the first opening 24 on the array substrate 1 is a rectangle. When the orthographic projection of the first opening 24 on the array substrate 1 is a rectangle, the touch trace 41 extends along the long side of the first opening 24. By arranging the touch trace 41 to extend along the long side of the first opening 24 as much as possible, the distance between the touch trace 41 and the first opening 24 can be increased, thereby further reducing the degree of mutual influence between the touch trace 41 and the signal trace 121 in the array substrate 1.

[0101] Referring to FIG. 1 to FIG. 6 , in some embodiments, the orthographic projection of the first opening 24 on the array substrate 1 is a polygon, and the first opening 24 includes a plurality of boundary lines. The first opening 24 and the touch trace 41 satisfy at least one of the following conditions:

[0102] (1) There is no first projection between a boundary line of the first opening 24 and the isolation opening 23;

[0103] (2) No first projection is distributed between the two opposite boundary lines of the first opening 24 and the adjacent isolation openings 23;

[0104] (3) No first projection is distributed between the multiple continuously connected boundary lines of the first opening 24 and the isolation opening 23;

[0105] (4) At least one first opening 24 is symmetrical with respect to the first symmetry axis, and at least one first opening 24 has a boundary not surrounded by the first projection that is symmetrical with respect to the first symmetry axis.

[0106] The orthographic projection of the first opening 24 on the array substrate 1 is a polygon, so that the first opening 24 has multiple boundary lines connected end to end. The following example illustrates the orthographic projection of the first opening 24 on the array substrate 1 as a quadrilateral.

[0107] For example, as shown in FIG5 , no first projection is distributed between a boundary line L1 of the first opening 24 and the isolation opening 23, and the first projection is arranged around the boundary lines of the first opening 24 other than the boundary line L1. When the first opening 24 is provided, by not distributing the first projection between a boundary line of the first opening 24 and the isolation opening 23, the isolation opening 23 and the first opening 24 have more space for distribution in the area between the boundary line L1 and the isolation opening 23, which helps to increase the density and size of the isolation openings 23 and the first opening 24.

[0108] For example, as shown in FIG6 , no first projection is distributed between the two opposing boundary lines of the first opening 24 and the adjacent isolation openings 23, and the first projection is arranged around the boundary lines of the first opening 24 other than the boundary lines L1 and L2. When the first opening 24 is opened, by setting the touch traces 41 not distributed between the two opposing boundary lines (L1 and L2) of the first opening 24 and the adjacent isolation openings 23, one isolation opening 23 and the first opening 24 have a larger distribution space in the area between the boundary line L1 and the isolation opening 23, and the other isolation opening 23 and the first opening 24 have a larger distribution space in the area between the boundary line L2 and the isolation opening 23, which is beneficial to improving the density and size of the isolation openings 23 and the first opening 24.

[0109] Exemplarily, as shown in Figure 7, no touch lines 41 are distributed between the multiple continuously connected boundary lines of the first opening 24 and the isolation opening 23, and the first projection is set around the other boundary lines of the first opening 24 except the boundary lines L1 and L3. When the first opening 24 is opened, by setting the multiple continuously connected boundary lines (L1 and L3) of the first opening 24 and the isolation opening 23 without distributing the touch lines 41, one isolation opening 23 and the first opening 24 both have a larger distributable space in the area between the boundary line L1 and the isolation opening 23, and the other isolation opening 23 and the first opening 24 both have a larger distributable space in the area between the boundary line L3 and the isolation opening 23, which is beneficial to improving the density and size of the isolation opening 23 and the first opening 24.

[0110] For example, as shown in FIG6 , the first opening 24 is symmetrical relative to the first axis of symmetry S1, and the boundary lines L1 and L2 of the first opening 24 not surrounded by the first projection are symmetrical relative to the first axis of symmetry S1. When the first opening 24 is formed, by setting the boundary lines L1 and L2 of the first opening 24 symmetrical relative to the first axis of symmetry S1 so that no touch traces 41 are distributed between adjacent isolation openings 23, one isolation opening 23 and the first opening 24 have a larger distribution space in the area between the boundary line L1 and the isolation opening 23, and the other isolation opening 23 and the first opening 24 have a larger distribution space in the area between the boundary line L2 and the isolation opening 23, which is beneficial for increasing the density and size of the isolation openings 23 and the first opening 24.

[0111] Those skilled in the art will appreciate that the shape of the orthographic projection of the first opening 24 on the array substrate 1 may also be a pentagon, a hexagon, a heptagon, and so on. For the same first opening 24, a touch trace 41 may not be distributed between one boundary line of the first opening 24, two opposing boundary lines, and multiple continuously connected boundary lines and the isolation opening 23. For example, as shown in FIG8 , the orthographic projection of the first opening 24 on the array substrate 1 is a hexagon. Among the boundary lines L1 to L6, the first projection of the touch trace 41 is not distributed between the boundary line L2 and the adjacent isolation opening 23; the first projection of the touch trace 41 is not distributed between the oppositely arranged boundary lines L2 and L5 and the adjacent isolation opening 23; and the first projection of the touch trace 41 is not distributed between the connected boundary lines L4, L5, and L6 and the adjacent isolation opening 23.

[0112] Referring to FIG. 1 and FIG. 5 , in some embodiments, the plurality of light-emitting units 31 include a first light-emitting unit 31 a for emitting a first color light and a second light-emitting unit 31 b for emitting a second color light. The plurality of isolation openings 23 include a first isolation opening 23 a and a second isolation opening 23 b. At least a portion of the first light-emitting unit 31 a is located within the first isolation opening 23 a, and at least a portion of the second light-emitting unit 31 b is located within the second isolation opening 23 b.

[0113] The plurality of first openings 24 include a plurality of first sub-openings 24 a . The first sub-openings 24 a are disposed between the first isolation openings 23 a and the second isolation openings 23 b adjacent to each other in the first direction X.

[0114] The first color light may be blue light, and the second color light may be red light. The first light-emitting unit 31a is configured to emit blue light, and the second light-emitting unit 31b is configured to emit red light. The plurality of first light-emitting units 31a and the plurality of second light-emitting units 31b may be alternately arranged along the first direction X. The plurality of first sub-openings 24a may be sequentially spaced apart along the first direction X and disposed between adjacent first light-emitting units 31a and second light-emitting units 31b, such that external light can enter from one side of the display panel through the first sub-openings 24a between the first light-emitting units 31a and the second light-emitting units 31b.

[0115] In some embodiments, the first projection portion is distributed along a plurality of continuously connected boundary lines of the first sub-opening 24 a , thereby increasing the distribution density of the touch traces 41 in the area where the first sub-opening 24 a is located and improving touch sensitivity.

[0116] Optionally, a first projection is distributed between the first sub-opening 24a and the first light-emitting unit 31a, and no first projection is distributed between the first sub-opening 24a and the second light-emitting unit 31b, and the projection area of ​​the first isolation opening 23a on the array substrate 1 is larger than the projection area of ​​the second isolation opening 23b on the array substrate 1.

[0117] Since the projection area of ​​the first isolation opening 23a on the array substrate 1 is larger than the projection area of ​​the second isolation opening 23b on the array substrate 1, the projection area of ​​the first light-emitting unit 31a located in the first isolation opening 23a on the array substrate 1 can be larger than the projection area of ​​the second light-emitting unit 31b located in the second isolation opening 23b on the array substrate 1. The first projection is distributed between the first sub-opening 24a and the first light-emitting unit 31a, and the first projection is not distributed between the first sub-opening 24a and the second light-emitting unit 31b. Therefore, compared with the first light-emitting unit 31a, the second light-emitting unit 31b has a larger light output angle, which is beneficial to improving the light output rate of the second light-emitting unit 31b.

[0118] Please refer to Figure 5. In some embodiments, the multiple light-emitting units 31 also include a third light-emitting unit 31c for emitting a third color light, the multiple isolation openings 23 also include a third isolation opening 23c, and at least a portion of the third light-emitting unit 31c is located within the third isolation opening 23c; the multiple first openings 24 also include a multiple second sub-openings 24b, and the second sub-openings 24b are arranged between adjacent third isolation openings 23c.

[0119] The third color light can be green, and the third light-emitting unit 31c is configured to emit green light. The third isolation openings 23c can be spaced apart along the second direction Y, and the second sub-openings 24b can be disposed between adjacent third isolation openings 23c along the first direction X. Providing the second sub-openings 24b between the third isolation openings 23c improves light transmittance between the third light-emitting units 31c.

[0120] In some embodiments, a plurality of first sub-openings 24 a are arranged in rows along the first direction X to form a plurality of rows of first sub-openings 24 a ; a plurality of second sub-openings 24 b are arranged in rows along the first direction X to form a plurality of rows of second sub-openings 24 b , and the second sub-openings 24 b and the first sub-openings 24 a are located in different rows.

[0121] Multiple rows of first sub-openings 24a can be arranged at intervals along the second direction Y. Multiple rows of second sub-openings 24b can be arranged at intervals along the second direction Y. The first sub-openings 24a and the second sub-openings 24b are located in different rows. For example, blue light emitting units 31a and red light emitting units 31b are alternately arranged to form a first pixel row, and multiple green light emitting units 31c are arranged to form a second pixel row. The first pixel row and the second pixel row are alternately arranged along the second direction Y. The first sub-opening 24a is disposed between the blue light emitting units 31a and the red light emitting units 31b that are spaced apart along the first direction X, and the second sub-opening 24b is disposed between the green light emitting units 31c that are spaced apart along the first direction X.

[0122] The second sub-openings 24b and the first sub-openings 24a are located in different rows, thereby simplifying the layout design of the first openings 24 and simplifying the layout design of the touch traces 41 corresponding to the first openings 24. Optionally, the second sub-openings 24b arranged in a row and the first sub-openings 24a arranged in a row are arranged in a second direction Y at intervals.

[0123] In some embodiments, portions of the first projection are distributed along two opposite boundary lines of the second sub-opening 24 b.

[0124] The first isolation opening 23a and the second isolation opening 23b are arranged along the second direction Y, and the second sub-opening 24b is located between the first isolation opening 23a and the second isolation opening 23b arranged along the second direction Y. The first projection is distributed between the second sub-opening 24b and the first isolation opening 23a and between the second sub-opening 24b and the second isolation opening 23b. The first projection is not distributed between the second sub-opening 24b and the adjacent third light-emitting unit 31c, which is beneficial to increasing the size of the second sub-opening 24b, thereby improving the transmittance.

[0125] Optionally, the projection area of ​​the third isolation opening 23c on the array substrate 1 is smaller than the projection area of ​​the first isolation opening 23a on the array substrate 1 and smaller than the projection area of ​​the second isolation opening 23b on the array substrate 1, so that the projection area of ​​the third light-emitting unit 31c located in the third isolation opening 23c on the array substrate 1 is smaller than the projection area of ​​the first light-emitting unit 31a in the first isolation opening 23a on the array substrate 1 and smaller than the projection area of ​​the second light-emitting unit 31b located in the second isolation opening 23b on the array substrate 1, the first projection is distributed between the second sub-opening 24b and the first isolation opening 23a, and between the second sub-opening 24b and the second isolation opening 23b, and the first projection is not distributed between the second sub-opening 24b and the adjacent third light-emitting unit 31c, so that compared with the first light-emitting unit 31a and the second light-emitting unit 31b, the third light-emitting unit 31c has a larger light output angle, which is beneficial to improving the light output rate of the third light-emitting unit 31c.

[0126] In some embodiments, the first projection surrounds the entire boundary of the first isolation opening 23a, at least a portion of the first projection surrounds a portion of the boundary of the second isolation opening 23b, and two opposite boundary lines of the second isolation opening 23b are not surrounded by the first projection.

[0127] The second isolation opening 23b is not surrounded by the first projection of the touch trace 41 along the first direction X toward the boundary line of the first isolation opening 23a, which helps to increase the length of the first opening 24 between the second isolation opening 23b and the first isolation opening 23a along the first direction X, thereby increasing the size of the first opening 24 and improving the transmittance.

[0128] Referring to FIG. 9 and FIG. 10 , in some embodiments, the touch traces 41 are enclosed into a plurality of grids 42 , and the plurality of grids 42 correspond one-to-one to a plurality of grid areas. At least one grid area 42 is provided with an isolation opening 23 and a first opening 24 adjacent to the isolation opening 23 .

[0129] The orthographic projection of the grid 42 on the array substrate 1 can completely overlap the grid area. A pixel light-emitting group 32 can be located within each grid area 42. For example, one first light-emitting unit 31a, one second light-emitting unit 31b, and two third light-emitting units 31c form a pixel light-emitting group 32, and the grid enclosed by the touch traces 41 corresponds to the pixel light-emitting group 32. The grid 42 can be laid repeatedly, simplifying the design of the touch traces 41.

[0130] In some embodiments, the touch lines 41 enclosing two adjacent grids 42 share a common touch line 41 .

[0131] For example, for a touch line 41 shared between two adjacent grids A and B, the touch line 41 is enclosed with other touch lines 41 to form grid A on one hand, and is enclosed with other touch lines 41 to form grid B on the other hand.

[0132] The touch lines 41 enclosing two adjacent grids 42 share a common touch line 41 , thereby increasing the proportion of touch lines 41 distributed between adjacent isolation openings 23 and reducing the space occupied by the touch lines 41 between adjacent isolation openings 23 , which is beneficial to increasing the size or distribution density of the isolation openings 23 .

[0133] In some embodiments, at least one grid 42 has symmetry.

[0134] The grid area 42 is set to be symmetrical to improve the uniformity of the distribution of the touch lines 41 .

[0135] In some embodiments, the plurality of isolation openings 23 include a first isolation opening 23a, the plurality of light-emitting units 31 include a first light-emitting unit 31a for emitting a first color light, and at least a portion of the first light-emitting unit 31a is located within the first isolation opening 23a; the orthographic projection of the touch trace 41 enclosing at least one grid 42 on the isolation structure 2 surrounds the entire boundary of the first isolation opening 23a.

[0136] The orthographic projection of the touch trace 41 on the isolation structure 2 surrounds the entire boundary of the first isolation opening 23a, thereby improving the touch sensitivity of the area where the first light-emitting units 31a are distributed. Optionally, among the light-emitting units 31 for emitting light of different colors, the first light-emitting units 31a have the largest projected area on the array substrate 1, thereby reducing the maximum spacing between adjacent touch traces 41 and increasing the distribution density of the touch traces 41.

[0137] In some embodiments, the plurality of isolation openings 23 include a second isolation opening 23b, the plurality of light-emitting units 31 include a second light-emitting unit 31b for emitting a second color of light, and at least a portion of the second light-emitting unit 31b is located within the second isolation opening 23b; at least one grid area 42 is provided with a second isolation opening 23b and first openings 24 located on opposite sides of the second isolation opening 23b;

[0138] There is no first projection distributed between the second isolation opening 23 b and the first opening 24 adjacent to the second isolation opening 23 b in the same grid area 42 .

[0139] Within the same grid area 42, a second isolation opening 23b is adjacent to at least one first opening 24, and no first projection is distributed between the second isolation opening 23b and the first opening 24 adjacent to the second isolation opening 23b, thereby increasing the length of the second isolation opening 23b along the direction where the touch traces 41 are not distributed. Alternatively, the first openings 24 may be located on opposite sides of the second isolation opening 23b along the first direction X, with no touch traces 41 distributed between the second isolation opening 23b and the first opening 24, thereby increasing the length of the second isolation opening 23b along the first direction X.

[0140] In some embodiments, the second isolation opening 23 b is symmetrical with respect to the second symmetry axis S2 , and a boundary of the second isolation opening 23 b not surrounded by the first projection is symmetrical with respect to the second symmetry axis S2 .

[0141] The boundary of the second isolation opening 23 b not surrounded by the first projection is symmetrical with respect to the second symmetry axis S2 , thereby increasing the length of the second isolation opening 23 b in a direction perpendicular to the second symmetry axis S2 .

[0142] In some embodiments, the plurality of isolation openings 23 include a third isolation opening 23c, the plurality of light-emitting units 31 include a third light-emitting unit 31c for emitting a third color light, and at least a portion of the third light-emitting unit 31c is located within the third isolation opening 23c; at least one grid area 42 is provided with a first opening 24 and third isolation openings 23c located on opposite sides of the first opening 24.

[0143] Third isolation openings 23 c are disposed on opposite sides of the first opening 24 to increase light transmittance within the grid region 42 and improve uniform light transmission within the grid region.

[0144] In some embodiments, no first projection is distributed between the third isolation opening 23 c and the first opening 24 adjacent to the third isolation opening 23 c in the same grid area 42 .

[0145] The third isolation opening 23 c and the first opening 24 adjacent to the third isolation opening 23 c in the same grid area 42 can be spaced apart along the first direction X. No first projection is distributed between the third isolation opening 23 c and the first opening 24 to increase the length of the first opening 24 along the first direction X.

[0146] A first light-emitting unit 31a, a second light-emitting unit 31b, and two third light-emitting units 31c are provided within the same grid area 42. Lines connecting the center points of the first light-emitting unit 31a, the second light-emitting unit 31b, and the third light-emitting unit 31c within the same grid area 42 form a virtual quadrilateral. For example, the virtual quadrilateral is shown by the dotted line in FIG10 .

[0147] The first and second light-emitting units 31a, 31b within the same grid area 42 can be arranged along the second direction Y, and the two third light-emitting units 31c can be arranged along the first direction X, with the first direction X intersecting the second direction Y. First sub-openings 24a are provided on either side of the second light-emitting unit 31b along the first direction X, and a second sub-opening 24b is provided between the two third light-emitting units 31c. This arrangement not only helps ensure good light transmittance in the area provided with the first openings 24, but also allows for a more compact arrangement of the light-emitting units 31, thereby improving the pixel density and display quality of the display panel.

[0148] In some embodiments, multiple grid areas 42 are arranged in rows along the first direction X and in columns along a second direction Y intersecting the first direction X. Within the same grid area 42, the first light-emitting units 31a and the second light-emitting units 31b are arranged at intervals along the second direction Y, and the two third light-emitting units 31c are arranged at intervals along the first direction X. Within the same grid area 42, two first openings 24 are provided on opposite sides of the first light-emitting unit 31a along the first direction X, and / or two first openings 24 are provided on opposite sides of the second light-emitting unit 31b along the first direction X, and / or at least one first opening 24 is provided between the two third light-emitting units 31c.

[0149] Those skilled in the art may arrange and combine the first openings 24 and the light-emitting units 31 according to the positional relationship within the aforementioned grid area 42 to obtain different arrangement schemes within the aforementioned grid area 42 .

[0150] Illustratively, within the same grid area 42 , two first openings 24 are provided on opposite sides of the first light emitting unit 31 a along the first direction X, and at least one first opening 24 is provided between two third light emitting units 31 c.

[0151] Multiple light-emitting units 31 form pixel light-emitting groups 32, which are arranged in an array. Each pixel light-emitting group 32 includes a red light-emitting unit 31b for emitting red light, two green light-emitting units 31c for emitting green light, and a blue light-emitting unit 31a for emitting blue light. First sub-openings 24a are provided on either side of the red light-emitting unit 31b. The green light-emitting unit 31c is arranged along the second direction Y between the first sub-opening 24a in the same grid area 42 and the first sub-opening 24a in another grid area 42. The red light-emitting unit 31b and the blue light-emitting unit 31a are spaced apart along the second direction Y, and the second sub-opening 24b can be provided between the red light-emitting unit 31b and the blue light-emitting unit 31a along the second direction Y. The two green light-emitting units 31c are spaced apart along the first direction X, and the second sub-opening 24b can be provided between the two green light-emitting units 31c along the first direction X.

[0152] Illustratively, within the same grid area 42 , two first openings 24 are provided on opposite sides of the second light emitting unit 31 b along the first direction X, and at least one first opening 24 is provided between two third light emitting units 31 c.

[0153] Multiple light-emitting units 31 form pixel light-emitting groups 32, which are arranged in an array. Each pixel light-emitting group 32 includes a red light-emitting unit 31b for emitting red light, two green light-emitting units 31c for emitting green light, and a blue light-emitting unit 31a for emitting blue light. First sub-openings 24a are provided on both sides of the blue light-emitting unit 31a. The green light-emitting unit 31c is arranged along the second direction Y between the first sub-opening 24a in the same grid area 42 and the first sub-opening 24a in another grid area 42. The red light-emitting unit 31b and the blue light-emitting unit 31a are spaced apart along the second direction Y, and the second sub-opening 24b can be provided between the red light-emitting unit 31b and the blue light-emitting unit 31a along the second direction Y. Two green light-emitting units 31c are spaced apart along the first direction X, and the second sub-opening 24b can be provided between the two green light-emitting units 31c along the first direction X.

[0154] Please refer to Figure 11. In some embodiments, the multiple first openings 24 include a third sub-opening 24c and a fourth sub-opening 24d. The first projection surrounds a portion of the boundary of the third sub-opening 24c, the portion of the first projection does not surround another portion of the boundary of the third sub-opening 24c, the portion of the first projection surrounds the entire boundary of the fourth sub-opening 24d, and the projection area of ​​the third sub-opening 24c on the array substrate 1 is larger than the projection area of ​​the fourth sub-opening 24d on the array substrate 1.

[0155] When designing the first opening 24, a certain amount of space must be reserved so that if the prepared touch trace 41 deviates, the touch trace 41 will not block the isolation opening 23 or the first opening 24. A portion of the touch trace 41 surrounds the entire boundary of the fourth sub-opening 24d, so that space must be reserved along the entire boundary of the fourth sub-opening 24d for the touch trace 41. The touch trace 41 does not surround a portion of the boundary of the third sub-opening 24c, so that space does not need to be reserved for the touch trace 41 in this portion of the boundary. This allows the design and preparation of a projected area of ​​the third sub-opening 24c on the array substrate 1 that is larger than the projected area of ​​the fourth sub-opening 24d on the array substrate 1. The larger third sub-opening 24c improves the light transmittance of the display panel.

[0156] In some embodiments, the third sub-opening 24c and the fourth sub-opening 24d each include a boundary line extending along the first direction X and a boundary line extending along the second direction Y, the first projection does not surround the boundary line of the third sub-opening 24c extending along the second direction Y, and the length of the third sub-opening 24c along the first direction X is greater than the length of the fourth sub-opening 24d along the first direction X.

[0157] Since the touch trace 41 does not surround the boundary line of the third sub-opening 24c extending along the second direction Y, the third sub-opening 24c extends along the first direction X to obtain a larger size, so that the length of the third sub-opening 24c along the first direction X is greater than the length of the fourth sub-opening 24d along the first direction X.

[0158] Referring to Figures 11 and 13, in some embodiments, the first opening 24 includes a first boundary line 2411 and a second boundary line 2412, at least a portion of the touch trace 41 is located between the first boundary line 2411 and the isolation opening 23, and the touch trace 41 is not located between the second boundary line 2412 and the isolation opening 23; the minimum distance H1 from the first boundary line 2411 to the boundary of the adjacent isolation opening 23 is greater than the minimum distance H2 from the second boundary line 2412 to the boundary of the adjacent isolation opening 23.

[0159] Since space needs to be reserved between the first boundary line 2411 and the isolation opening 23 for setting the touch trace 41, the minimum distance H1 from the first boundary line 2411 to the boundary of the adjacent isolation opening 23 is greater than the minimum distance H2 from the second boundary line 2412 to the boundary of the adjacent isolation opening 23, thereby increasing the minimum distance between the isolation opening 23 and the first opening 24.

[0160] In some embodiments, the minimum distance H1 from the first boundary line 2411 to the boundary of the adjacent isolation opening 23 is greater than or equal to 11 μm, and the minimum distance H2 from the second boundary line 2412 to the boundary of the adjacent isolation opening 23 is greater than or equal to 5.5 μm. This reduces or prevents the touch trace 41 from blocking the isolation opening 23 or the first opening 24 due to manufacturing errors.

[0161] For example, the minimum distance H1 between the first boundary line 2411 and the boundary of the adjacent isolation opening 23 is 11 μm, and the minimum distance H2 between the second boundary line 2412 and the boundary of the adjacent isolation opening 23 is 5.5 μm. For another example, the minimum distance H1 between the first boundary line 2411 and the boundary of the adjacent isolation opening 23 is 15 μm, and the minimum distance H2 between the second boundary line 2412 and the boundary of the adjacent isolation opening 23 is 7 μm.

[0162] In some embodiments, the minimum distance from the boundary of the isolation opening 23 to the first projection is greater than or equal to 5 μm to prevent manufacturing errors from causing the touch trace 41 to block light from the light-emitting unit 31 in the isolation opening 23. Optionally, the minimum distance from the boundary of the isolation opening 23 to the first projection is 5 μm, 6 μm, 10 μm, 15 μm, etc.

[0163] Referring to FIG. 13 , in some embodiments, the isolation opening 23 includes a fourth isolation opening 23d and a fifth isolation opening 23e. The light-emitting units within the fourth isolation opening 23d and the light-emitting units within the fifth isolation opening 23e may emit the same or different colors. The minimum distance H3 from the boundary of the fourth isolation opening 23d to the touch trace 41 is the same as the minimum distance H4 from the boundary of the fifth isolation opening 23e to the touch trace 41. The minimum distance H4 from the fourth isolation opening 23d to an adjacent touch trace 41 is the same as the minimum distance H4 from the fourth isolation opening 23d to another adjacent touch trace 41.

[0164] The light-emitting unit placed in the fourth isolation opening 23d can be configured to emit any of red, blue, and green light. The light-emitting unit placed in the fifth isolation opening 23e can be configured to emit any of red, blue, and green light. The fourth isolation opening 23d and the fifth isolation opening 23e can have the same or different sizes and shapes. For example, the fourth isolation opening 23d and the fifth isolation opening 23e can be isolation openings among the first isolation opening 23a, the second isolation opening 23b, and the third isolation opening 23c for accommodating light-emitting units of the same color. The fourth isolation opening 23d and the fifth isolation opening 23e can be any two of the first isolation opening 23a, the second isolation opening 23b, and the third isolation opening 23c. By setting the minimum distance H3 from the boundary of the fourth isolation opening 23d to the touch trace equal to the minimum distance H4 from the boundary of the fifth isolation opening 23e to the touch trace, this prevents or reduces the possibility of the touch trace blocking the light-emitting units in the fourth isolation opening 23d and the fifth isolation opening 23e due to manufacturing errors. For example, a red light-emitting unit 31 for emitting red light, a green light-emitting unit 31 for emitting green light, and a blue light-emitting unit 31 for emitting blue light are arranged in rows at intervals along the first direction X, and the light-emitting units arranged in rows are arranged at intervals along the second direction Y. The first opening 24 is provided on one side of the light-emitting unit 31 along the second direction Y. A first projection is provided on one side of the first opening 24 along the second direction Y, and no first projection is provided on the other side of the first opening 24 along the second direction Y.

[0165] 12 , in some embodiments, at least a portion of the first projection surrounds the third boundary line 2413 and the fourth boundary line 2414 of the first opening 24 , and the minimum distance from the first projection to the third boundary line 2413 is different from the minimum distance from the touch trace 41 to the fourth boundary line 2414 .

[0166] The third boundary line 2413 and the fourth boundary line 2414 extend in different directions. Because the distances between adjacent first openings 24 and isolation openings 23 are different, the minimum distance from the first projection to the third boundary line 2413 and the minimum distance from the first projection to the fourth boundary line 2414 are different. This ensures that the minimum distance from the first projection to the isolation opening 23 is greater than a preset threshold, preventing the touch trace 41 from affecting the light emission of the light-emitting unit 31 in the isolation opening 23.

[0167] Referring to Figures 14 and 15 , in some embodiments, the display panel includes a first display area AA1 and a second display area AA2, and the plurality of first openings 24 are distributed in the first display area AA1. For example, the plurality of first openings 24 are distributed only in the first display area AA1. For another example, the plurality of first openings 24 are distributed not only in the first display area AA1 but also in the second display area AA2, and the arrangement of the plurality of first openings 24 in the first display area AA1 is the same as the arrangement of the plurality of first openings 24 in the second display area AA2.

[0168] The display area AA is used for displaying images and includes a first display area AA1 and a second display area AA2. Compared to the second display area AA2, the first display area AA1 can also be used to transmit light to a light sensor. The first display area AA1 can be a display area with a light sensor positioned underneath. The light sensor can be a camera or an infrared sensor. The first display area AA1 is the aperture area of ​​the display panel. Related components, such as an optical sensor, can be positioned beneath the screen of the first display area AA1. The optical sensor receives light transmitted through the first display area AA1 to perform a camera function.

[0169] At least part of the first opening 24 is located in the first display area AA1. The first opening 24 is arranged in the first display area AA1 to improve the light transmittance of the first display area AA1. The light-emitting units 31 are distributed in the display area so that the entire display area can display light. The first opening 24 is mainly arranged in the first display area AA1, and external light can pass through the first opening 24 to illuminate the optical sensor. The touch wiring 41 can be distributed in the display area so that the entire display area can achieve touch. Optionally, the light transmittance of the display panel in the first display area AA1 is greater than or equal to 0.5%, so that the light sensor arranged on one side of the first display area AA1 can receive a sufficient amount of light.

[0170] In some embodiments, the touch traces 41 in the second display area AA2 have the same pattern as the touch traces 41 in the first display area AA1 ; the pixel arrangement in the second display area AA2 is the same as the pixel arrangement in the first display area AA1 .

[0171] The pattern of the touch traces 41 can be identical, meaning that the orthographic projections of the touch traces 41 enclosing the grid 42 on the array substrate 1 are identical, i.e., the orthographic projection of the grid 42 of the first display area AA1 on the array substrate 1 is identical to the orthographic projection of the grid 42 of the second display area AA2 on the array substrate 1. The pixel arrangement of the second display area AA2 is identical to that of the first display area AA1, i.e., the composition and arrangement of the luminous pixel groups 32 are identical. By arranging the touch traces 41 in the second display area AA2 to have the same pattern as the touch traces 41 in the first display area AA1, and by arranging the pixel arrangement of the second display area AA2 to be identical to that of the first display area AA1, the first display area AA1 and the second display area AA2 achieve the same display effect in both the display and non-display states, thereby avoiding or reducing uneven brightness of the display panel.

[0172] In some embodiments, the distribution density of the touch lines 41 in the first display area AA1 is smaller than the distribution density of the touch lines 41 in the second display area AA2, that is, per unit area, the orthographic projection area of ​​the touch lines 41 in the first display area AA1 on the array substrate 1 is smaller than the orthographic projection area of ​​the touch lines 41 in the second display area AA2 on the array substrate 1.

[0173] The arrangement of the touch traces 41 in the second display area AA2 is shown in FIG16 , and the arrangement of the touch traces 41 in the first display area AA1 is shown in FIG3 . The touch traces 41 may include touch receiving traces and touch transmitting traces, which work together to implement the touch function of the display panel. In this embodiment, the distribution density of the touch traces 41 in the first display area AA1 is less than the distribution density of the touch traces 41 in the second display area AA2. For example, the distribution density of the touch traces 41 in the second display area AA2 is substantially the same as the distribution density of the touch traces 41 in the display function area in the related art. Therefore, the distribution density of the touch traces 41 in the first display area AA1 is less than the distribution density of the touch traces 41 in the hole area in the related art. Therefore, this embodiment reduces the number of touch lines 41 distributed on the first display area AA1, and differentiates the distribution density of the touch lines 41 in the first display area AA1 and the second display area AA2, which can greatly reduce the touch lines 41 blocking the light reaching the components in the first display area AA1, improve the transmittance of the first display area AA1, and thus improve the reliability of the components set in the first display area AA1.

[0174] Based on the above design, this embodiment improves the transmittance of the first display area AA1 and reduces the mutual interference between the touch lines 41 and the signal lines in the array substrate 1 by setting the distribution density of the touch lines 41 in the first display area AA1 to be smaller than the distribution density of the touch lines 41 in the second display area AA2, thereby improving the reliability of the display panel.

[0175] Referring to FIG. 15 , in some embodiments, the touch trace 41 includes multiple straight segments, and the distances between the orthographic projections of at least two straight segments on the array substrate 1 and the orthographic projections of the isolation opening 23 on the array substrate 1 are the same.

[0176] The straight line segment can extend along the boundary between the first opening 24 and the isolation opening 23. Optionally, the straight line segment extends between the red light emitting unit 31b and the green light emitting unit 31c, and the straight line segment extends between the blue light emitting unit 31a and the green light emitting unit 31c. Setting the straight line segments at the same distance from the isolation opening 23 can avoid or reduce color shift and improve display quality.

[0177] In some embodiments, the minimum distance between the orthographic projection of the first opening 24 on the array substrate 1 and the orthographic projection of the touch trace 41 on the array substrate 1 is greater than or equal to 50 μm to prevent the offset touch trace 41 from blocking the first opening 24 .

[0178] In some embodiments, the first opening 24 is located between adjacent isolation openings 23 . Optionally, the isolation structure 2 is in a grid shape, the isolation openings 23 are arranged in an array, and the first opening 24 is disposed between adjacent isolation openings 23 .

[0179] 17 and 18 , it should be noted that the isolation structure 2 refers to an undercut structure that is “large at the top and small at the bottom” and can isolate the light-emitting materials of adjacent light-emitting units. The isolation structure 2 can be a structure formed by a single film layer, or a structure formed by stacking multiple film layers. Exemplarily, when the isolation structure 2 is a single-layer structure, the cross-sectional shape of the isolation structure 2 can be an inverted trapezoid that is “large at the top and small at the bottom”. In some embodiments, the isolation structure 2 includes a first portion 21 and a second portion 22 that are stacked, and the first portion 21 is arranged on a side of the second portion 22 close to the array substrate 1, and the orthographic projection of the first portion 21 on the array substrate 1 is located within the orthographic projection of the second portion 22 on the array substrate 1.

[0180] The isolation structure 2 encloses an isolation opening 23 to define the area within which the light-emitting functional layer is disposed. The isolation structure 2 comprises a first portion 21 and a second portion 22, which are stacked. The orthographic projection of the first portion 21 on the array substrate 1 lies within the orthographic projection of the second portion 22 on the array substrate 1. This results in a larger cross-sectional area at the end of the isolation structure 2 facing away from the array substrate 1, while a smaller cross-sectional area at the end of the isolation structure 2 closer to the array substrate 1. Along the direction from the isolation structure 2 to the array substrate 1, the second portion 22 completely obscures the first portion 21.

[0181] When fabricating the light-emitting unit 31, the luminescent material A used to fabricate the light-emitting unit 31 can be deposited onto the isolation structure 2 using an evaporation technique. Because the second portion 22 obscures the first portion 21, the luminescent material A used to fabricate the light-emitting unit 31 creates a significant drop at the boundary of the second portion 22. This makes it difficult for the luminescent material A within the isolation opening 23 to connect with the luminescent material A on the second portion 22, resulting in a break, leaving the luminescent material A spaced apart between adjacent isolation openings 23. The luminescent material A on the second portion 22 can be removed as needed. Compared to the related art method of fabricating the light-emitting functional layer through evaporation using a mask, the present application utilizes the first portion 21 and the second portion 22, allowing the light-emitting unit 31 within the isolation opening 23 to be fabricated without a metal mask, thus eliminating the cost of preparing a metal mask. Directly fabricating the high-precision isolation structure 2 is easier than fabricating the light-emitting functional layer through evaporation using a high-precision metal mask. This reduces the manufacturing process requirements for the display panel structure provided by the present application, resulting in a highly consistent display panel. The luminescent material can be an indium-containing complex.

[0182] In some embodiments, the orthographic projection area of ​​the surface of the second portion 22 facing away from the array substrate 1 on the array substrate 1 is smaller than the orthographic projection area of ​​the surface of the second portion 22 close to the array substrate 1 on the array substrate 1 .

[0183] The second portion 22 extends outward a predetermined distance relative to the first portion 21, that is, the orthographic projection area of ​​the surface of the second portion 22 facing away from the array substrate 1 on the array substrate 1 is smaller than the orthographic projection area of ​​the surface of the second portion 22 close to the array substrate 1 on the array substrate 1, so that the second portion 22 has an inclined slope structure, so that the pattern of the light-emitting functional layer is defined by the second portion 22.

[0184] In some embodiments, the cross-sectional area of ​​the second portion 22 gradually decreases in a direction away from the array substrate 1 .

[0185] The cross section of the second portion 22 can be a trapezoid with the bottom edge facing the array substrate 1, so that the second portion 22 has a sloped surface, which is conducive to the preparation material being disconnected at the partition boundary line, forming a state in which part of the preparation material is located on the second portion 22 and part of the preparation material is located in the isolation opening 23.

[0186] In some embodiments, the orthographic projection area of ​​the surface of the first portion 21 facing away from the array substrate 1 on the array substrate 1 is smaller than the orthographic projection area of ​​the surface of the second portion 22 close to the array substrate 1 on the array substrate 1 .

[0187] That is, the second portion 22 extends outward relative to the first portion 21, so that the pattern of the light-emitting functional layer is limited by the second portion 22. The orthographic projection of the first portion 21 on the array substrate 1 is located within the orthographic projection of the second portion 22 on the array substrate 1. At this time, the first portion 21 is recessed relative to the second portion 22 in a direction away from the isolation opening 23. When preparing the light-emitting functional layer, a large drop in height is generated at the edge of the isolation structure 2, and the first portion 21 is recessed. This makes it difficult for the light-emitting functional layer to connect outside the isolation structure 2, resulting in a break, forming mutually isolated light-emitting functional layers.

[0188] In some embodiments, the light emitting unit 31 includes a first electrode 33 and a light emitting layer 34 . The first electrode 33 is connected to the light emitting layer 34 on a side close to the array substrate 1 , and an edge of the first electrode 33 overlaps the isolation structure 2 .

[0189] The first electrode 33 can be a cathode or an anode and is connected to the light-emitting layer 34 to drive the light-emitting layer 34 to emit light. If the first electrode 33 is a cathode, the isolation structure 2 transmits a VSS signal. If the first electrode 33 is an anode, the isolation structure 2 transmits a VDD signal.

[0190] The light-emitting layer 34 includes at least a light-emitting layer (EML). In addition, it may also include one or more of a hole injection layer (HIL), a hole transport layer (HTL), an electron injection layer (EIL), an electron transport layer (ETL), a hole block layer (HBL), and an electron block layer (EBL). Alternatively, the light-emitting functional portion may also be a stacked light-emitting structure, that is, including at least two light-emitting layers and a charge generation layer (CGL) located between each adjacent light-emitting layer.

[0191] In one embodiment, the first portion 21 includes at least one metal layer. In one example, the material of the first portion 21 includes at least one of a metal and a metal oxide. For example, the metal may be silver, copper, titanium, aluminum, or the like. The metal oxide may be tin oxide, zinc oxide, cadmium oxide, indium oxide, indium tin oxide, zinc indium oxide, zinc gallium oxide, zinc aluminum oxide, titanium tantalum oxide, or the like.

[0192] In one embodiment, the isolation structure 2 further includes a supporting portion, which is disposed between the array substrate 1 and the first portion 21 .

[0193] In one example, the supporting portion includes a conductive material, which is beneficial for further reducing the resistance of the isolation structure 2 and thus reducing the power consumption of the display panel 100 .

[0194] In some embodiments, an edge of the first electrode 33 overlaps the isolation structure 2 .

[0195] The edge of the first electrode 33 overlaps with the isolation structure 2 . The isolation structure 2 can supply power to the first electrode 33 and also enable the adjacent first electrodes 33 to be conductive, thereby forming a surface electrode with a conductive surface.

[0196] When the first electrode 33 and the isolation structure 2 overlap to form a surface electrode, the touch layer 4 and the driving circuit layer 12 can be shielded by the surface electrode.

[0197] In some embodiments, the light-emitting unit 31 includes multiple second electrodes 35, which are located on the side of the light-emitting layer 34 that is closest to the array substrate 1. The light-emitting unit 31 includes the second electrode 35, the light-emitting layer 34, and the first electrode 33, which are at least partially located within the isolation opening 23 and are stacked in a direction away from the array substrate 1. One of the first electrode 33 and the second electrode 35 can serve as an anode electrode, and the other can serve as a cathode electrode. The first electrode 33, the light-emitting layer 34, and the second electrode 35 can be stacked and contacted in a third direction Z to achieve electrical continuity among the first electrode 33, the light-emitting layer 34, and the second electrode 35. Optionally, the first electrode 33 serves as a cathode electrode, and the second electrode 35 serves as an anode electrode.

[0198] 19 and 20 , the orthographic projection of the isolation structure 2 on the array substrate 1 is a mesh structure. In this way, the isolation structure 2 can better separate the second electrode layer to form a plurality of first electrodes 33 spaced apart and respectively located in the isolation openings 23 .

[0199] In some possible implementations, please refer to Figure 18 again, the first electrode 33 of the light-emitting unit 31 is electrically connected to the first part 21; please refer to Figure 20, and / or the isolation structure 2 also includes a third part 25 located on the side of the first part 21 facing the array substrate 1, and the first electrode 33 of the light-emitting unit 31 is electrically connected to the third part 25; the material of the third part 25 includes molybdenum metal; and / or the material of the first part 21 includes aluminum metal; and / or the material of the second part 22 includes titanium metal.

[0200] In some embodiments, the display panel also includes a pixel definition layer 8 arranged between the array substrate 1 and the isolation structure 2, the pixel definition layer 8 includes a pixel opening 81, the pixel opening 81 is connected to the isolation opening 23, and the orthographic projection of the pixel opening 81 on the array substrate 1 is located within the orthographic projection range of the isolation opening 23 on the array substrate 1.

[0201] The pixel definition layer 8 is located on one side of the array substrate 1 and encloses a pixel opening 81. The light emitting unit 31 can be at least partially disposed within the pixel opening 81 to achieve light emitting display of the display panel. The pixel opening can be disposed corresponding to the isolation opening 23.

[0202] In some embodiments, the isolation structure 2 is disposed on a side of the pixel definition layer 8 facing away from the array substrate 1 , and the light-emitting functional layer is at least partially disposed within the pixel opening 81 .

[0203] The isolation structure 2 is disposed on the side of the pixel definition layer 8 facing away from the array substrate 1, and the orthographic projection of the pixel opening 81 on the array substrate 1 is located within the orthographic projection of the isolation opening 23 on the array substrate 1. The isolation structure 2 can be directly disposed on the side of the pixel definition layer 8 facing away from the array substrate 1, with the pixel definition layer 8 supporting the isolation structure 2. The orthographic projection of the pixel opening 81 on the array substrate 1 can be located within the orthographic projection of the isolation opening 23 on the array substrate 1. The area of ​​the isolation opening 23 is larger than that of the pixel opening 81, which can reduce the impact of the isolation structure 2 on the light output viewing angle of the light-emitting functional layer.

[0204] Optionally, there are multiple pixel openings 81, which are spaced apart, and the isolation structure 2 can be disposed on the pixel definition layer 8 between at least a portion of two adjacent pixel openings 81. Optionally, the isolation structure 2 can be disposed around at least a portion of the pixel openings 81.

[0205] At least part of the first electrode 33 extends from the pixel opening 81 to the side of the pixel definition layer 8 away from the array substrate 1 and is electrically contacted with the third part 25 or the first part 21 in the isolation structure 2. The third part 25 or the first part 21 of the isolation structure 2 can connect adjacent first electrodes 33, or connect the first electrode 33 to other circuits, thereby making it easier for the isolation structure 2 to separate the second electrode layer to form the first electrode 33 and electrically connect the first electrodes 33.

[0206] In some possible implementations, referring to FIG. 21 , the array substrate 1 includes a substrate 11 and a signal trace 121 located on one side of the substrate 11 , and the orthographic projection of the touch trace 41 on the substrate 11 does not overlap with the orthographic projection of the signal trace 121 on the substrate 11 .

[0207] The array substrate 1 includes data lines and / or scan lines, and voltage jumps in these signal lines 121 can affect the touch accuracy of the touch lines 41. Therefore, the orthographic projection of the touch lines 41 on the substrate 11 is set to not overlap with the orthographic projection of the signal lines 121 on the substrate 11, thereby reducing the impact of the signal lines 121 on the touch lines 41.

[0208] In some possible implementations, please refer to Figure 2, the display panel also includes a first encapsulation layer 71 located on the side of the first electrode 33 away from the array substrate 1, the first encapsulation layer 71 includes a plurality of encapsulation units 711, and the orthographic projection of the encapsulation unit 711 on the array substrate 1 covers the orthographic projection of the light-emitting unit on the array substrate 1.

[0209] The first encapsulation layer 71 is an inorganic encapsulation layer. The isolation structure 2 includes a first side close to the array substrate 1, a side away from the array substrate 1, and side surfaces. Each independent encapsulation unit 711 extends from the sidewall of the isolation structure 2 to the side of the isolation structure 2 away from the array substrate 1. The encapsulation units 711 are in contact with both the sidewall of the isolation structure 2 and the surface of the isolation structure 2 away from the array substrate 1. Each encapsulation unit 711 is spaced apart on the side of the isolation structure 2 away from the array substrate 1. This greatly improves the independent encapsulation effect of the pixels, thereby further optimizing the optical performance of the display panel.

[0210] Optionally, referring to FIG. 20 , the display panel further includes a second encapsulation layer 72 located on a side of the first encapsulation layer 71 away from the array substrate 1 ; the side of the second encapsulation layer 72 away from the array substrate 1 has a flat surface.

[0211] The second encapsulation layer 72 is an organic encapsulation layer, which can be formed by inkjet printing. The second encapsulation layer 72 can fill the side of the isolation structure 2 away from the array substrate 1, the isolation opening 23 and the first opening 24, etc., and can better protect the light-emitting unit 31, etc.

[0212] Optionally, referring to FIG. 18 , the display panel further includes a third encapsulation layer 73 located on a side of the second encapsulation layer 72 away from the array substrate 1, and the touch layer 4 is located on a side of the third encapsulation layer 73 away from the array substrate 1. The third encapsulation layer 73 is an inorganic encapsulation layer that can further enhance the encapsulation effect of the light-emitting unit 31 and the like.

[0213] In some possible implementations, please refer to Figure 1 again, in the touch layer 4, adjacent touch lines 41 are connected to form a grid 42, and the orthographic projection of the isolation opening 23 and / or the first opening 24 on the array substrate 1 at least partially overlaps with the orthographic projection of the mesh of the grid 42 on the array substrate 1.

[0214] The touch lines 41 are interconnected to form a grid 42, which includes multiple mesh holes. The orthographic projections of the mesh holes on the array substrate 1 are set to at least partially overlap with the orthographic projections of the isolation opening 23 and / or the first opening 24 on the array substrate 1, which can increase the transmittance of the isolation opening 23 and / or the first opening 24.

[0215] In some possible implementations, referring again to FIG. 1 , the orthographic projection of at least one isolation opening 23 and / or at least one first opening 24 on the array substrate 1 is located within the orthographic projection of a mesh of the grid 42 on the array substrate 1. The orthographic projection area of ​​the mesh on the array substrate 1 is larger than the orthographic projection area of ​​the isolation opening 23 and / or the first opening 24 on the array substrate 1. Therefore, the orthographic projection of one mesh on the array substrate 1 can cover the orthographic projection of at least one isolation opening 23 and / or at least one first opening 24 on the array substrate 1. In this way, the density of the meshes of the grid 42 of the touch trace 41 can be appropriately set based on the isolation openings 23 and / or the first openings 24.

[0216] Alternatively, referring again to FIG. 1 , the orthographic projection area of ​​the meshes of the grid 42 of the second display area AA2 on the array substrate 1 is smaller than the orthographic projection area of ​​the meshes of the grid 42 of the first display area AA1 on the array substrate 1. Thus, while the touch traces 41 are arranged substantially identically in the first display area AA1 and the second display area AA2, the light transmittance of the first display area AA1 can be improved by setting the mesh density of the grid 42 of the second display area AA2 to be smaller than that of the grid 42 of the first display area AA1.

[0217] Optionally, the ratio of the area of ​​the orthographic projection of the mesh holes of the grid 42 of the second display area AA2 on the array substrate 1 to the area of ​​the orthographic projection of the mesh holes of the grid 42 of the first display area AA1 on the array substrate 1 is 1 / 2-1 / 16, for example, 1 / 2, 1 / 4, 1 / 8, or 1 / 16. Reasonable setting of the ratio of the mesh density of the grid 42 of the second display area AA2 to the first display area AA1 not only increases the light transmittance of the first display area AA1, but also minimizes the difference in the density of the touch traces 41 between the first display area AA1 and the second display area AA2, thereby improving the display uniformity of the display panel.

[0218] For example, in some embodiments, referring to FIG. 3 again, the ratio of the orthographic projection area of ​​the mesh holes of the grid 42 of the second display area AA2 on the array substrate 1 to the orthographic projection area of ​​the mesh holes of the grid 42 of the first display area AA1 on the array substrate 1 is 1 / 2.

[0219] In other embodiments, referring to Figures 22 and 23 , the ratio of the orthographic projection area of ​​the mesh holes of the grid 42 of the second display area AA2 on the array substrate 1 to the orthographic projection area of ​​the mesh holes of the grid 42 of the first display area AA1 on the array substrate 1 is 1 / 4. As shown in Figure 22 , the grid 42 is provided with a plurality of isolation openings 23 and a plurality of first openings 24.

[0220] In summary, the present application can improve the transmittance of the first display area AA1 and reduce the mutual interference between the touch lines 41 and the signal lines in the array substrate 1 by setting the distribution density of the touch lines 41 in the first display area AA1 to be smaller than the distribution density of the touch lines 41 in the second display area AA2, thereby improving the reliability of the display panel.

[0221] An embodiment of the second aspect of the present application also provides a display panel. Please refer to Figures 1 to 23 again. The display panel includes an array substrate 1, an isolation structure 2, a light-emitting functional layer and a touch layer 4. The isolation structure 2 is arranged on one side of the array substrate 1, and a plurality of isolation openings 23 and a plurality of first openings 24 are provided on the isolation structure 2; the light-emitting functional layer includes a plurality of light-emitting units 31, and at least part of the light-emitting units 31 is arranged in the isolation opening 23; the touch layer 4 is arranged on the side of the isolation structure 2 away from the array substrate 1, and the touch layer 4 includes a plurality of touch traces 41, and the orthographic projection of the touch trace 41 on the array substrate 1 is located in the orthographic projection of the isolation structure 2 on the array substrate 1, and the orthographic projection of the touch trace 41 on the isolation structure 2 is a first projection, and the first projection is not distributed between at least some adjacent isolation openings 23 and first openings 24.

[0222] The array substrate 1, isolation structure 2, light-emitting functional layer and touch layer 4 provided in the second aspect can refer to the arrangement of the array substrate 1, isolation structure 2, light-emitting functional layer and touch layer 4 provided in the first aspect, and will not be repeated here.

[0223] In the embodiment provided in the present application, by setting the first opening 24, the light transmittance of the display panel can be improved; by positioning the orthographic projection of the touch line 41 on the array substrate 1 within the orthographic projection of the isolation structure 2 on the array substrate 1, the touch layer 4 is prevented from or reduced from blocking the light entering the first opening 24 or blocking the light exiting the isolation opening 23, thereby improving the light transmittance of the display panel; by setting the first projection not to be distributed between at least some adjacent isolation openings 23 and the first opening 24, it is beneficial to increase the size of the first opening 24 and improve the light transmittance.

[0224] In some embodiments, the plurality of light-emitting units 31 include a first light-emitting unit 31a for emitting a first color light and a second light-emitting unit 31b for emitting a second color light, the plurality of isolation openings 23 include a first isolation opening 23a and a second isolation opening 23b, at least a portion of the first light-emitting unit 31a is located within the first isolation opening 23a, and at least a portion of the second light-emitting unit 31b is located within the second isolation opening 23b;

[0225] The plurality of first openings 24 include a plurality of first sub-openings 24 a . The first sub-openings 24 a are disposed between the first isolation openings 23 a and the second isolation openings 23 b adjacent to each other in the first direction X.

[0226] The first color light may be blue light, and the second color light may be red light. The first light-emitting unit 31a is configured to emit blue light, and the second light-emitting unit 31b is configured to emit red light. The plurality of first light-emitting units 31a and the plurality of second light-emitting units 31b may be alternately arranged along the first direction X. The plurality of first sub-openings 24a may be sequentially spaced apart along the first direction X and disposed between adjacent first light-emitting units 31a and second light-emitting units 31b, such that external light can enter from one side of the display panel through the first sub-openings 24a between the first light-emitting units 31a and the second light-emitting units 31b.

[0227] Optionally, a touch line 41 is distributed between the first sub-opening 24a and the first light-emitting unit 31a, and no touch line 41 is distributed between the first sub-opening 24a and the second light-emitting unit 31b, and the projected area of ​​the first isolation opening 23a on the array substrate 1 is larger than the projected area of ​​the second isolation opening 23b on the array substrate 1.

[0228] Since the projected area of ​​the first isolation opening 23a on the array substrate 1 is larger than the projected area of ​​the second isolation opening 23b on the array substrate 1, the projected area of ​​the first light-emitting unit 31a located in the first isolation opening 23a on the array substrate 1 can be larger than the projected area of ​​the second light-emitting unit 31b located in the second isolation opening 23b on the array substrate 1. The touch line 41 is distributed between the first sub-opening 24a and the first light-emitting unit 31a, and the touch line 41 is not distributed between the first sub-opening 24a and the second light-emitting unit 31b. Therefore, compared with the first light-emitting unit 31a, the second light-emitting unit 31b has a larger light output angle, which is beneficial to improving the light output rate of the second light-emitting unit 31b.

[0229] In some embodiments, the multiple light-emitting units 31 also include a third light-emitting unit 31c for emitting a third color light, the multiple isolation openings 23 also include a third isolation opening 23c, and at least a portion of the third light-emitting unit 31c is located within the third isolation opening 23c; the multiple first openings 24 also include a plurality of second sub-openings 24b, and the second sub-openings 24b are arranged between adjacent third isolation openings 23c.

[0230] The third color light can be green, and the third light-emitting unit 31c is configured to emit green light. The third isolation openings 23c can be spaced apart along the second direction Y, and the second sub-openings 24b can be disposed between adjacent third isolation openings 23c along the first direction X. Providing the second sub-openings 24b between the third isolation openings 23c improves light transmittance between the third light-emitting units 31c.

[0231] The first isolation opening 23a and the second isolation opening 23b are arranged along the second direction Y. The second sub-opening 24b is located between the first isolation opening 23a and the second isolation opening 23b arranged along the second direction Y. Touch lines 41 are distributed between the second sub-opening 24b and the first isolation opening 23a and between the second sub-opening 24b and the second isolation opening 23b. No touch lines 41 are distributed between the second sub-opening 24b and the adjacent third light-emitting unit 31c. This helps to increase the length of the third isolation opening 23c along the first direction X and increase the size or distribution density of the third light-emitting unit 31c.

[0232] Optionally, the projection area of ​​the third isolation opening 23c on the array substrate 1 is smaller than the projection area of ​​the first isolation opening 23a on the array substrate 1 and smaller than the projection area of ​​the second isolation opening 23b on the array substrate 1, so that the projection area of ​​the third light-emitting unit 31c located in the third isolation opening 23c on the array substrate 1 is smaller than the projection area of ​​the first light-emitting unit 31a in the first isolation opening 23a on the array substrate 1 and smaller than the projection area of ​​the second light-emitting unit 31b located in the second isolation opening 23b on the array substrate 1, and the touch wiring 41 is distributed between the second sub-opening 24b and the first isolation opening 23a, and between the second sub-opening 24b and the second isolation opening 23b, and no touch wiring 41 is distributed between the second sub-opening 24b and the adjacent third light-emitting unit 31c, so that compared with the first light-emitting unit 31a and the second light-emitting unit 31b, the third light-emitting unit 31c has a larger light output angle, which is beneficial to improving the light output rate of the third light-emitting unit 31c.

[0233] In some embodiments, the touch traces 41 are enclosed into a plurality of grids 42 , and the plurality of grids 42 correspond to a plurality of grid areas one by one. At least one grid area is provided with an isolation opening 23 and a first opening 24 adjacent to the isolation opening 23 .

[0234] The touch lines 41 enclosing two adjacent grids 42 share a common touch line 41 .

[0235] A pixel light-emitting group 32 can be set within a grid area 42. For example, one first light-emitting unit 31a, one second light-emitting unit 31b, and two third light-emitting units 31c form a pixel light-emitting group 32, and the pixel light-emitting group 32 is set within the grid area 42 enclosed by the touch traces 41. The grid area 42 can be laid repeatedly, thereby simplifying the design of the touch traces 41. The touch traces 41 enclosing two adjacent grid areas 42 have a shared touch trace 41, thereby increasing the proportion of touch traces 41 distributed between adjacent isolation openings 23, reducing the space occupied by the touch traces 41 between adjacent isolation openings 23, and facilitating an increase in the size or distribution density of the isolation openings 23.

[0236] In some embodiments, the plurality of isolation openings 23 include a first isolation opening 23a, the plurality of light-emitting units 31 include a first light-emitting unit 31a for emitting a first color light, and at least a portion of the first light-emitting unit 31a is located within the first isolation opening 23a; a first projection of the touch trace 41 enclosing at least one grid area 42 surrounds the entire boundary of the first isolation opening 23a;

[0237] The plurality of isolation openings 23 include a second isolation opening 23b. The plurality of light-emitting units 31 include a second light-emitting unit 31b for emitting a second color of light. At least a portion of the second light-emitting unit 31b is located within the second isolation opening 23b. At least one grid region 42 is provided with a second isolation opening 23b and first openings 24 located on opposite sides of the second isolation opening 23b.

[0238] Multiple isolation openings 23 include a third isolation opening 23c, multiple light-emitting units 31 include a third light-emitting unit 31c for emitting a third color light, and at least a portion of the third light-emitting unit 31c is located within the third isolation opening 23c; at least one grid area 42 is provided with a first opening 24 and third isolation openings 23c located on opposite sides of the first opening 24.

[0239] The second isolation opening 23b is not surrounded by the first projection of the touch trace 41 along the first direction X toward the boundary of the first isolation opening 23a, which helps to increase the length of the second isolation opening 23b along the first direction X and improve the size or distribution density of the second light-emitting units 31b. The third isolation openings 23c are provided on opposite sides of the first opening 24 to increase the light transmittance within the grid area 42 and improve the uniformity of light transmission within the grid area.

[0240] An embodiment of the third aspect of the present application also provides a display panel. Please refer to Figures 1 to 23 again. The display panel includes an array substrate 1, an isolation structure 2, a light-emitting functional layer and a touch layer 4. The isolation structure 2 is arranged on one side of the array substrate 1, and multiple isolation openings 23 and multiple first openings 24 are provided on the isolation structure 2; the light-emitting functional layer includes multiple light-emitting units 31, and at least part of the light-emitting units 31 is arranged in the isolation opening 23; the touch layer 4 is arranged on the side of the isolation structure 2 away from the array substrate 1, and the touch layer 4 includes multiple touch traces 41, and the touch traces 41 are enclosed into multiple grids 42, and an isolation opening 23 and a first opening 24 are provided in the grid area corresponding to at least one grid 42.

[0241] The array substrate 1, isolation structure 2, light-emitting functional layer and touch layer 4 provided in the third aspect can refer to the array substrate 1, isolation structure 2, light-emitting functional layer and touch layer 4 provided in the first aspect, and will not be repeated here.

[0242] Multiple grids 42 can correspond one-to-one to multiple grid areas. A pixel light-emitting group 32 can be set in a grid area 42. For example: one first light-emitting unit 31a, one second light-emitting unit 31b and two third light-emitting units 31c constitute a pixel light-emitting group 32, and the pixel light-emitting group 32 is set in the grid area 42 enclosed by the touch wiring 41. The grid area 42 can be laid repeatedly, thereby simplifying the design of the touch wiring 41. There is a common touch wiring 41 between the touch wirings 41 enclosing two adjacent grid areas 42, thereby increasing the proportion of touch wirings 41 distributed between adjacent isolation openings 23, reducing the space occupied by the touch wiring 41 between adjacent isolation openings 23, and helping to increase the size or distribution density of the isolation openings 23.

[0243] In the embodiment provided in the present application, by setting the first opening 24, the light transmittance of the display panel can be improved; by positioning the orthographic projection of the touch line 41 on the array substrate 1 within the orthographic projection of the isolation structure 2 on the array substrate 1, the touch layer 4 is prevented from or reduced from blocking the light entering the first opening 24 or blocking the light exiting the isolation opening 23, thereby improving the light transmittance of the display panel; by providing the isolation opening 23 and the first opening 24 in the grid area corresponding to the grid 42, the light transmittance of the area corresponding to the grid 42 is improved.

[0244] In some implementations, the plurality of light-emitting units 31 include a second light-emitting unit 31 b for emitting light of a second color, the plurality of isolation openings 23 include a second isolation opening 23 b, and at least a portion of the second light-emitting unit 31 b is located within the second isolation opening 23 b; at least one grid area 42 includes the second isolation opening 23 b and the first openings 24 located on opposite sides of the second isolation opening 23 b;

[0245] The orthographic projection of the touch trace 41 on the isolation structure 2 is a first projection. In the grid area corresponding to the same grid 42 , no first projection is distributed between the second isolation opening 41 b and the first opening 24 adjacent to the second isolation opening 23 b .

[0246] The second isolation opening 23b is not surrounded by the first projection of the touch trace 41 along the first direction X toward the boundary of the first isolation opening 23a, which helps to increase the length of the second isolation opening 23b along the first direction X and improve the size or distribution density of the second light-emitting units 31b. The third isolation openings 23c are provided on opposite sides of the first opening 24 to increase the light transmittance within the grid area 42 and improve the uniformity of light transmission within the grid area.

[0247] In some embodiments, the plurality of isolation openings 23 include a third isolation opening 23c, the plurality of light-emitting units 31 include a third light-emitting unit 31c for emitting a third color light, and at least a portion of the third light-emitting unit 31c is located within the third isolation opening 23c; at least one grid area 42 is provided with a first opening 24 and third isolation openings 23c located on opposite sides of the first opening 24.

[0248] The orthographic projection of the touch trace 41 on the isolation structure 2 is a first projection. In the grid area corresponding to the same grid 42 , no first projection is distributed between the third isolation opening 23 c and the first opening 24 adjacent to the third isolation opening 23 c.

[0249] The first color light may be blue light, and the second color light may be red light. The first light-emitting unit 31a is configured to emit blue light, and the second light-emitting unit 31b is configured to emit red light. The plurality of first light-emitting units 31a and the plurality of second light-emitting units 31b may be alternately arranged along the first direction X. The plurality of first sub-openings 24a may be sequentially spaced apart along the first direction X and disposed between adjacent first light-emitting units 31a and second light-emitting units 31b, such that external light can enter from one side of the display panel through the first sub-openings 24a between the first light-emitting units 31a and the second light-emitting units 31b.

[0250] Optionally, a touch line 41 is distributed between the first sub-opening 24a and the first light-emitting unit 31a, and no touch line 41 is distributed between the first sub-opening 24a and the second light-emitting unit 31b, and the projected area of ​​the first isolation opening 23a on the array substrate 1 is larger than the projected area of ​​the second isolation opening 23b on the array substrate 1.

[0251] Since the projected area of ​​the first isolation opening 23a on the array substrate 1 is larger than the projected area of ​​the second isolation opening 23b on the array substrate 1, the projected area of ​​the first light-emitting unit 31a located in the first isolation opening 23a on the array substrate 1 can be larger than the projected area of ​​the second light-emitting unit 31b located in the second isolation opening 23b on the array substrate 1. The touch line 41 is distributed between the first sub-opening 24a and the first light-emitting unit 31a, and the touch line 41 is not distributed between the first sub-opening 24a and the second light-emitting unit 31b. Therefore, compared with the first light-emitting unit 31a, the second light-emitting unit 31b has a larger light output angle, which is beneficial to improving the light output rate of the second light-emitting unit 31b.

[0252] In some embodiments, the multiple light-emitting units 31 also include a third light-emitting unit 31c for emitting a third color light, the multiple isolation openings 23 also include a third isolation opening 23c, and at least a portion of the third light-emitting unit 31c is located within the third isolation opening 23c; the multiple first openings 24 also include a plurality of second sub-openings 24b, and the second sub-openings 24b are arranged between adjacent third isolation openings 23c.

[0253] The third color light can be green, and the third light-emitting unit 31c is configured to emit green light. The third isolation openings 23c can be spaced apart along the second direction Y, and the second sub-openings 24b can be disposed between adjacent third isolation openings 23c along the first direction X. Providing the second sub-openings 24b between the third isolation openings 23c improves light transmittance between the third light-emitting units 31c.

[0254] The first isolation opening 23a and the second isolation opening 23b are arranged along the second direction Y. The second sub-opening 24b is located between the first isolation opening 23a and the second isolation opening 23b arranged along the second direction Y. Touch lines 41 are distributed between the second sub-opening 24b and the first isolation opening 23a and between the second sub-opening 24b and the second isolation opening 23b. No touch lines 41 are distributed between the second sub-opening 24b and the adjacent third light-emitting unit 31c. This helps to increase the length of the third isolation opening 23c along the first direction X and increase the size or distribution density of the third light-emitting unit 31c.

[0255] Optionally, the projection area of ​​the third isolation opening 23c on the array substrate 1 is smaller than the projection area of ​​the first isolation opening 23a on the array substrate 1 and smaller than the projection area of ​​the second isolation opening 23b on the array substrate 1, so that the projection area of ​​the third light-emitting unit 31c located in the third isolation opening 23c on the array substrate 1 is smaller than the projection area of ​​the first light-emitting unit 31a in the first isolation opening 23a on the array substrate 1 and smaller than the projection area of ​​the second light-emitting unit 31b located in the second isolation opening 23b on the array substrate 1, and the touch wiring 41 is distributed between the second sub-opening 24b and the first isolation opening 23a, and between the second sub-opening 24b and the second isolation opening 23b, and no touch wiring 41 is distributed between the second sub-opening 24b and the adjacent third light-emitting unit 31c, so that compared with the first light-emitting unit 31a and the second light-emitting unit 31b, the third light-emitting unit 31c has a larger light output angle, which is beneficial to improving the light output rate of the third light-emitting unit 31c.

[0256] An embodiment of the fourth aspect of the present application also provides a display panel. Please refer to Figures 1 to 23 again. The display panel includes an array substrate 1, a light-emitting functional layer and a touch layer 4; the light-emitting functional layer includes a plurality of light-emitting units 31, and at least part of the light-emitting unit 31 is arranged in the isolation opening 23; the touch layer 4 is arranged on the side of the isolation structure 2 away from the array substrate 1, and the touch layer 4 includes a plurality of touch traces 41. The orthographic projection of the touch traces 41 on the array substrate 1 is located within the orthographic projection of the isolation structure 2 on the array substrate 1. The touch traces 41 are enclosed into a plurality of grids 42. The grid area corresponding to at least one grid 42 is provided with a light-emitting area A1 and a light-transmitting area A2, and the light-emitting area A1 is provided with a light-emitting unit 31.

[0257] The array substrate 1 , the light-emitting functional layer and the touch layer 4 provided in the fourth aspect can refer to the arrangement of the array substrate 1 , the light-emitting functional layer and the touch layer 4 provided in the first aspect, and will not be repeated here.

[0258] The light-emitting area A1 can be realized by providing the aforementioned isolation opening 23 to emit light, and the light-transmitting area A2 can be realized by providing the aforementioned first opening 24 to transmit light. Alternatively, this can be achieved by increasing the light transmittance of the materials used to prepare the various film layers in the light-transmitting area A2.

[0259] In the embodiment provided in the present application, the light transmittance of the display panel can be improved by setting a light-transmitting area A2; by setting a grid area corresponding to at least one grid 42 to set a luminous A1 and a light-transmitting area A2, the light transmittance of the area corresponding to the grid 42 can be improved.

[0260] In some embodiments, the display panel includes an isolation structure 2, which is arranged on one side of the array substrate 1. A plurality of isolation openings 23 and a plurality of first openings 24 are provided on the isolation structure 2. At least a portion of the light-emitting unit 31 is located within the isolation opening 23. The first opening 24 is located in the light-transmitting area A2.

[0261] The isolation structure 2 provided in the fourth aspect can refer to the setting of the isolation structure 2 provided in the first aspect, and will not be repeated here.

[0262] The first opening 24 is provided in the light-transmitting area A2 to improve the light transmittance of the light-transmitting area A2.

[0263] Optionally, the orthographic projection of the touch line 41 on the array substrate 1 is located within the orthographic projection of the isolation structure 2 on the array substrate 1 to avoid or reduce the touch layer 4 blocking the light entering the first opening 24 or blocking the light emitted from the light-emitting unit 31, thereby improving the light transmittance of the display panel.

[0264] An embodiment of the fifth aspect of the present application also provides a display panel. Please refer to Figures 1 to 23 again. The display panel includes an array substrate 1, an isolation structure 2, a light-emitting functional layer and a touch layer 4. The isolation structure 2 is arranged on one side of the array substrate 1. A plurality of isolation openings 23 and a plurality of first openings 24 are provided on the isolation structure 2; the light-emitting functional layer includes a plurality of light-emitting units 31, and at least part of the light-emitting units 31 is arranged in the isolation opening 23; the touch layer 4 is arranged on the side of the isolation structure 2 away from the array substrate 1, and the touch layer 4 includes a plurality of touch traces 41. The orthographic projection of the touch traces 41 on the array substrate 1 is located within the orthographic projection of the isolation structure 2 on the array substrate 1. The light transmittance of the display panel is greater than or equal to 0.5%.

[0265] The array substrate 1, isolation structure 2, light-emitting functional layer and touch layer 4 provided in the fifth aspect can refer to the array substrate 1, isolation structure 2, light-emitting functional layer and touch layer 4 provided in the first aspect, and will not be repeated here.

[0266] In the embodiment provided in the present application, by setting a first opening 24, the light transmittance of the display panel can be improved; by positioning the orthographic projection of the touch line 41 on the array substrate 1 within the orthographic projection of the isolation structure 2 on the array substrate 1, the touch layer 4 is prevented from or reduced from blocking the light entering the first opening 24 or blocking the light exiting the isolation opening 23, thereby improving the light transmittance of the display panel; by adjusting the position of the touch line 41, the light transmittance of the display panel is set to be greater than or equal to 0.5%, which is conducive to setting a light sensing element on one side of the display panel.

[0267] The display panel includes a first display area and a second display area, a plurality of light emitting units are located in the first display area and the second display area, a plurality of first openings are located in the first display area, and a light transmittance of the display panel in the first display area is greater than or equal to 0.5%.

[0268] The embodiment of the sixth aspect of the present application further provides a display device, comprising a display panel according to any one of the embodiments of the first, second, third, fourth, and fifth aspects. Since the display device provided by the embodiment of the sixth aspect of the present application comprises the display panel according to any one of the embodiments of the first, second, third, fourth, and fifth aspects, the display device provided by the embodiment of the sixth aspect of the present application has the beneficial effects of the display panel according to any one of the embodiments of the first, second, third, fourth, and fifth aspects, which will not be further elaborated here.

[0269] The display device in the embodiments of the present application includes but is not limited to mobile phones, personal digital assistants (PDAs), tablet computers, e-books, televisions, access control systems, smart landline phones, consoles, and other devices with display functions.

[0270] Referring to Figures 24, 25 and 26, an embodiment of the present application provides a display module 10, which includes a display panel 100, a plurality of first openings 24 and a plurality of touch electrode portions 123. The display panel 100 has a display area AA, and a first display area AA1 is provided in the display area AA. The plurality of first openings 24 are provided on the display panel 100 at intervals from each other and are located in the first display area AA1. The plurality of touch electrode portions 123 are provided on the light-emitting side of the display panel 100 and are located in the first display area AA1; the orthographic projection of the touch electrode portion 123 on the display panel 100 is staggered with the first opening 24, that is, the orthographic projection of the touch electrode portion 123 on the display panel 100 does not overlap with the first opening 24.

[0271] The touch electrode portions 123 are arranged at intervals along the first direction X. Each touch electrode portion 123 includes a plurality of touch sub-patterns 1231 arranged at intervals along the first direction X. Each touch sub-pattern 1231 extends along the second direction Y. The first direction X intersects the second direction Y. At least a portion of the first opening 24 is located between two adjacent touch sub-patterns 1231.

[0272] It is understood that the display panel 100 may include an array substrate 1, a light-emitting unit, and an encapsulation layer (not shown) that are stacked. The first display area AA1 is equivalent to a light-transmitting area, and the number of first display areas AA1 may be one or more; at the same time, a second display area AA2 is also provided in the display area AA, and the second display area AA2 is equivalent to an opaque display area. The multiple touch electrode portions 123 may include multiple first touch electrode portions and multiple second touch electrode portions, wherein the first touch electrode portions may be RX electrodes and the second touch electrode portions may be TX electrodes. Furthermore, the second display area AA2 is provided with multiple first touch electrodes serving as RX electrodes and multiple second touch electrodes serving as TX electrodes, the first touch electrode portions being electrically connected to the corresponding first touch electrodes, and the second touch electrode portions being electrically connected to the corresponding second touch electrodes. Exemplarily, the display module 10 includes a touch layer 4, and the touch layer 4 includes a touch electrode portion 123, a first touch electrode, and a second touch electrode. The touch electrode portion 123 may also be the touch trace 41 , and the touch sub-pattern 1231 may be formed by enclosing a portion of the touch trace 41 .

[0273] In the embodiment of the present application, the touch sub-patterns 1231 extend along the second direction Y, which is equivalent to making the touch sub-patterns 1231 strip-shaped. By having each touch electrode portion 123 include multiple touch sub-patterns 1231 spaced apart along the first direction X, an area without touch patterns is formed between two adjacent touch sub-patterns 1231. Compared to the conventional arrangement of densely spaced touch patterns, the embodiment of the present application helps reduce the pattern density of the touch electrode portion 123. Furthermore, since at least part of the first opening 24 is located between two adjacent touch sub-patterns 1231, part of the periphery of the first opening 24 will inevitably not surround the touch sub-pattern 1231. Compared with the traditional technology in which the touch pattern is arranged around the entire periphery of the first opening 24, the pattern density of the touch electrode outside the first opening 24 is reduced, thereby reducing the possibility of radio frequency interference or signal crosstalk between the touch electrode portion 123 in the first display area AA1 and the signal line 121 in the display panel 100 through the first opening 24, thereby improving the performance of the display module 10.

[0274] It should be noted that, in the embodiments provided in the present application, FIG. 26 to FIG. 30 and FIG. 17 are all partial schematic diagrams of a touch electrode portion 123 .

[0275] In one embodiment, as shown in Figures 26 and 27, the display panel 100 includes a plurality of pixel rows 113a, which are arranged in a first display area AA1 at intervals along a first direction X. Each pixel row 113a includes a plurality of light-emitting units arranged in a second direction Y. At least one pixel row 113a is provided between two adjacent touch sub-patterns 1231, wherein a first opening 24 is provided between at least some of the adjacent two light-emitting units in the same pixel row 113a located between the two touch sub-patterns 1231. It will be understood that the pixel rows 113a can be pixel rows or pixel columns. This facilitates the arrangement of the first openings 24 and the touch sub-patterns 1231, thereby reducing the possibility of radio frequency interference or signal crosstalk between the touch electrode portion 123 in the first display area AA1 and the signal traces 121 in the display panel 100 through the first openings 24.

[0276] It should be noted that when multiple pixel rows 113a are provided between two touch sub-patterns 1231, only one of the multiple pixel rows 113a may have a first opening 24. In this pixel row 113a, the first opening 24 may be provided between two partially adjacent light-emitting units 31, or between any two adjacent light-emitting units 31. Furthermore, in the multiple pixel rows 113a, each pixel row 113a may have a first opening 24. In each pixel row 113a, the first opening 24 may be provided between two partially adjacent light-emitting units 31, or between any two adjacent light-emitting units.

[0277] In one embodiment, each touch sub-pattern 1231 is disposed around at least one pixel row 113a. This not only helps to fully utilize the layout space on the display panel 100, but also reduces the impact of the touch sub-pattern 1231 on light emission of the display panel 100.

[0278] In one embodiment, as shown in Figures 26 and 27 , the touch sub-pattern 1231 includes two first routing portions 12311 spaced apart along a first direction X, each extending along a second direction Y. Here, the first routing portions 12311 are equivalent to strip-shaped routing. This simplifies the pattern structure of the touch sub-pattern 1231, facilitating layout and reducing the pattern density of the touch electrode portion 123.

[0279] In one embodiment, a pixel row 113a is provided between two first trace portions 12311 in the same touch sub-pattern 1231. This allows a touch sub-pattern 1231 to occupy a smaller space, making it easier to arrange more touch sub-patterns 1231 within a limited area. This increases the capacitance of the touch electrode portion 123, reduces the impedance of the touch electrode portion 123, and thus improves touch performance.

[0280] In one embodiment, within a touch sub-pattern 1231, the pixel row 113a between two first trace portions 12311 has a first centerline (not shown) parallel to the second direction Y. The touch sub-pattern 1231 is symmetrically arranged about the first centerline. This helps maintain symmetry between the touch sub-pattern 1231 and the light-emitting units 31 in the pixel row 113a, thereby alleviating the visual color shift problem caused by the asymmetric structure of the touch sub-pattern 1231.

[0281] In one embodiment, the touch sub-patterns 1231 in the same touch electrode portion 123 are evenly arranged, which is beneficial for improving touch performance and display effects.

[0282] In one embodiment, as shown in FIG. 26 , all first openings 24 are located between two adjacent touch sub-patterns 1231. That is, no first openings 24 are provided between two first trace portions 12311 of the same touch sub-pattern 1231. This minimizes the possibility of radio frequency interference or signal crosstalk between the touch electrode portion 123 and the signal traces 121 in the display panel 100 through the first openings 24.

[0283] In one embodiment, as shown in Figures 27 and 28, the first opening 24 includes a first opening and a second first opening. The first opening is provided between two adjacent touch sub-patterns 1231, and the second first opening is provided between two first trace portions 12311 of the same touch sub-pattern 1231. This is equivalent to providing the first opening 24 not only between adjacent touch sub-patterns 1231 but also between two first trace portions 12311 of the same touch sub-pattern 1231, which helps improve the light transmittance of the light-transmitting area, thereby enhancing the performance of the under-screen device.

[0284] In one embodiment, as shown in FIG28 , the touch sub-pattern 1231 further includes a first compensation portion 12312, which is disposed between and electrically connects the two first trace portions 12311. The provision of the first compensation portion 12312 can compensate for the decrease in touch capacitance caused by the reduced pattern density of the touch electrode portion 123, thereby improving touch performance.

[0285] In one embodiment, as shown in Figures 26 to 29 , the plurality of pixel rows 113a include a plurality of first pixel rows 113a1 and a plurality of second pixel rows 113a2, which are alternately arranged along a first direction X. The first pixel rows 113a1 include a plurality of first light-emitting units 31a and a plurality of second light-emitting units 31b alternately arranged along a second direction Y. The second pixel rows 113a2 include a plurality of third light-emitting units 31c alternately arranged along the second direction Y. Touch sub-patterns 1231 are disposed around the peripheries of some of the first pixel rows 113a1, i.e., among all the first pixel rows 113a1, a portion of the first pixel rows 113a1 have touch sub-patterns 1231 disposed around the peripheries. This helps reduce the pattern density of the touch electrode portion 123.

[0286] It is understood that in the drawings shown in Figures 26 to 28, the pixel rows 113a are pixel columns. In the drawing shown in Figure 10, the pixel rows 113a are pixel rows.

[0287] In one embodiment, a first pixel row 113 a 1 and two second pixel rows 113 a 2 are provided between two adjacent touch sub-patterns 1231 .

[0288] Furthermore, as shown in FIG26 , a first opening 24 is provided between at least some of the adjacent third light-emitting units 31c in the same second pixel row 113a2. Thus, the touch sub-pattern 1231 is provided on only one side of the periphery of the first opening 24 in the second pixel row 113a2. This helps reduce the pattern density of the touch electrodes around the first opening 24, thereby reducing the possibility of radio frequency interference or signal crosstalk.

[0289] In one embodiment, a first opening 24 is provided between adjacent first light emitting units 31a and second light emitting units 31b in the first pixel row 113a1 between two adjacent touch sub-patterns 1231. This helps to further improve the light transmission performance of the light-transmitting area.

[0290] In one embodiment, as shown in FIG27 , a first opening 24 is provided between adjacent first light-emitting units 31a and second light-emitting units 31b in the same first pixel row 113a1. That is, a first opening 24 is provided in each first pixel row 113a1. Furthermore, a first opening 24 is provided between adjacent first light-emitting units 31a and second light-emitting units 31b in the same first pixel row 113a1. This further improves the light transmission performance of the light-transmitting area.

[0291] In one embodiment, as shown in FIG30 , the touch sub-pattern 1231 further includes a second compensation portion 12313. The second compensation portion 12313 is provided on at least one first routing portion 12311, and the second compensation portion 12313 is provided on a side of the first routing portion 12311 away from another first routing portion 12311. The provision of the second compensation portion 12313 can compensate for the decrease in touch capacitance caused by the reduced pattern density of the touch electrode portion 123, thereby improving touch performance.

[0292] In one embodiment, a second compensation portion 12313 is provided on each side of the two first wiring portions 12311 facing away from each other. Specifically, as shown in FIG30 , in the first pixel row 113a1, a first opening 24 is provided between adjacent first and second light-emitting units 31a, 31b. In the second pixel row 113a2, a first opening 24 is provided between a portion of adjacent third light-emitting units 31c, while a first opening 24 is not provided between another portion of adjacent third light-emitting units 31c. The second compensation portion 12313 is provided between the other portion of adjacent third light-emitting units 31c.

[0293] This is beneficial for further improving the touch performance on the one hand, and on the other hand, since the second compensation portion 12313 is farther away from the first opening 24 , the pattern density is increased without increasing radio frequency interference.

[0294] In one embodiment, the display module 10 further includes a bridging layer 13 . The bridging layer 13 is disposed on a side of the touch layer 4 away from the array substrate 1 . The bridging layer 13 is used to electrically connect two adjacent first touch electrodes (or second touch electrodes).

[0295] 24 to 31 , an embodiment of the present application provides a display module 10, which includes a display panel 100, a plurality of first openings 24, and a plurality of touch electrode portions 123. The display panel 100 has a display area AA, in which a first display area AA1 is provided. The plurality of first openings 24 are arranged in the first display area AA1 of the display panel 100 at intervals. The plurality of touch electrode portions 123 are arranged on the light-emitting side of the display panel 100 and are located in the first display area AA1. Each touch electrode portion 123 includes at least one touch sub-pattern 1231. The orthographic projection of the touch sub-pattern 1231 on the display panel 100 is staggered with respect to the first opening 24, and the orthographic projection surrounds at least a portion of the outer periphery of the first opening 24.

[0296] It is understood that the display panel 100 may include a stacked array substrate 1, a light-emitting unit, and an encapsulation layer. The first display area AA1 corresponds to a light-transmitting area, and the number of first display areas AA1 may be one or more. Furthermore, a second display area AA2 is provided within the display area AA, and the second display area AA2 corresponds to a non-light-transmitting display area. The multiple touch electrode sections 123 may include multiple first touch electrode sections and multiple second touch electrode sections, wherein the first touch electrode sections may be RX electrodes and the second touch electrode sections may be TX electrodes. Furthermore, the second display area AA2 includes multiple first touch electrodes serving as RX electrodes and multiple second touch electrodes serving as TX electrodes. The first touch electrode sections are electrically connected to corresponding first touch electrodes, and the second touch electrode sections are electrically connected to corresponding second touch electrodes. Furthermore, the display module 10 includes a touch layer 4, which includes the touch electrode section 123, the first touch electrodes, and the second touch electrodes.

[0297] The display module 10 provided in the embodiment of the present application comprises at least one touch sub-pattern 1231 in the touch electrode portion 123. The orthographic projection of the touch sub-pattern 1231 on the display panel 100 is offset from the first opening 24 and surrounds at least a portion of the outer periphery of the first opening 24. Thus, compared to conventional arrangements in which the touch pattern surrounds the entire periphery of the first opening 24, in the embodiment of the present application, at least a portion of the outer periphery of the first opening 24 does not necessarily surround the touch sub-pattern 1231. This reduces the pattern density of the touch electrodes outside the first opening 24, thereby reducing the possibility of radio frequency interference or signal crosstalk between the touch electrode portion 123 in the first display area AA1 and the signal traces 121 in the display panel 100 through the first opening 24, thereby improving the performance of the display module 10.

[0298] In one embodiment, as shown in FIG. 26 , each touch electrode portion 123 includes a plurality of touch sub-patterns 1231 spaced apart along a first direction X, each touch sub-pattern 1231 extending along a second direction Y. The first direction X intersects the second direction Y. At least a portion of the first opening 24 is located between two adjacent touch sub-patterns 1231 .

[0299] In the embodiment of the present application, the touch sub-patterns 1231 extend along the second direction Y, which is equivalent to making the touch sub-patterns 1231 strip-shaped. By having each touch electrode portion 123 include multiple touch sub-patterns 1231 spaced apart along the first direction X, an area without touch patterns is formed between two adjacent touch sub-patterns 1231. Compared to the conventional arrangement of densely spaced touch patterns, the embodiment of the present application helps reduce the pattern density of the touch electrode portion 123.

[0300] In one embodiment, as shown in Figures 26 and 27, the display panel 100 includes a plurality of pixel rows 113a, which are arranged in a first display area AA1 at intervals along a first direction X. Each pixel row 113a includes a plurality of light-emitting units arranged in a second direction Y. At least one pixel row 113a is provided between two adjacent touch sub-patterns 1231, wherein a first opening 24 is provided between at least some of the adjacent two light-emitting units in the same pixel row 113a located between the two touch sub-patterns 1231. It will be understood that the pixel rows 113a can be pixel rows or pixel columns. This facilitates the arrangement of the first openings 24 and the touch sub-patterns 1231, thereby reducing the possibility of radio frequency interference or signal crosstalk between the touch electrode portion 123 in the first display area AA1 and the signal traces 121 in the display panel 100 through the first openings 24.

[0301] It should be noted that when multiple pixel rows 113a are provided between two touch sub-patterns 1231, only one of the multiple pixel rows 113a may have a first opening 24. In this pixel row 113a, the first opening 24 may be provided between two partially adjacent light-emitting units, or between any two adjacent light-emitting units. Furthermore, in the multiple pixel rows 113a, each pixel row 113a may have a first opening 24. In each pixel row 113a, the first opening 24 may be provided between two partially adjacent light-emitting units, or between any two adjacent light-emitting units.

[0302] In one embodiment, each touch sub-pattern 1231 is disposed around at least one pixel row 113a. This not only helps to fully utilize the layout space on the display panel 100, but also reduces the impact of the touch sub-pattern 1231 on light emission of the display panel 100.

[0303] In one embodiment, the touch sub-pattern 1231 includes two first trace portions 12311 spaced apart along the first direction X, each extending along the second direction Y. Here, the first trace portions 12311 are equivalent to strip traces. This simplifies the pattern structure of the touch sub-pattern 1231, facilitating layout and reducing the pattern density of the touch electrode portion 123.

[0304] In one embodiment, a pixel row 113a is provided between two first trace portions 12311 in the same touch sub-pattern 1231. This allows a touch sub-pattern 1231 to occupy a smaller space, making it easier to arrange more touch sub-patterns 1231 within a limited area. This increases the capacitance of the touch electrode portion 123, reduces the impedance of the touch electrode portion 123, and thus improves touch performance.

[0305] In one embodiment, within a touch sub-pattern 1231, the pixel row 113a between two first trace portions 12311 has a first centerline (not shown) parallel to the second direction Y. The touch sub-pattern 1231 is symmetrically arranged about the first centerline. This helps maintain symmetry between the touch sub-pattern 1231 and the light-emitting units in the pixel row 113a, thereby alleviating the visual color shift problem caused by the asymmetric structure of the touch sub-pattern 1231.

[0306] In one embodiment, as shown in FIG. 26 , all first openings 24 are located between two adjacent touch sub-patterns 1231. That is, no first openings 24 are provided between two first trace portions 12311 of the same touch sub-pattern 1231. This minimizes the possibility of radio frequency interference or signal crosstalk between the touch electrode portion 123 and the signal traces 121 in the display panel 100 through the first openings 24.

[0307] In one embodiment, the first opening 24 includes a first opening and a second first opening. The first opening is provided between two adjacent touch sub-patterns 1231, and the second first opening is provided between two first trace portions 12311 of the same touch sub-pattern 1231. This is equivalent to providing the first opening 24 not only between adjacent touch sub-patterns 1231 but also between two first trace portions 12311 of the same touch sub-pattern 1231, which helps improve the light transmittance of the light-transmitting area and thus enhances the performance of the under-screen device.

[0308] In one embodiment, as shown in FIG28 , the touch sub-pattern 1231 further includes a first compensation portion 12312, which is disposed between and electrically connects the two first trace portions 12311. The provision of the first compensation portion 12312 can compensate for the decrease in touch capacitance caused by the reduced pattern density of the touch electrode portion 123, thereby improving touch performance.

[0309] In one embodiment, as shown in FIG30 , the touch sub-pattern 1231 further includes a second compensation portion 12313. The second compensation portion 12313 is provided on at least one first routing portion 12311, and the second compensation portion 12313 is provided on a side of the first routing portion 12311 away from another first routing portion 12311. The provision of the second compensation portion 12313 can compensate for the decrease in touch capacitance caused by the reduced pattern density of the touch electrode portion 123, thereby improving touch performance.

[0310] In one embodiment, a second compensation portion 12313 is provided on each side of the two first wiring portions 12311 that are opposite to each other.

[0311] Specifically, as shown in FIG30 , in the first pixel row 113a1, a first opening 24 is provided between adjacent first and second light-emitting units 31a and 31b. In the second pixel row 113a2, a first opening 24 is provided between a portion of adjacent third light-emitting units 31c, while a first opening 24 is not provided between another portion of adjacent third light-emitting units 31c. The second compensation portion 12313 is provided between the other portion of adjacent third light-emitting units 31c.

[0312] This is beneficial for further improving the touch performance on the one hand, and on the other hand, since the second compensation portion 12313 is farther away from the first opening 24 , the pattern density is increased without increasing radio frequency interference.

[0313] In one embodiment, as shown in Figures 31 and 32 , the display panel 100 includes a plurality of pixel light-emitting groups 32, each of which has at least one first opening 24 defined therein. The orthographic projection of the touch sub-pattern 1231 on the display panel 100 surrounds the pixel light-emitting groups 32. This arrangement effectively surrounds the pixel light-emitting groups 32, thereby reducing the pattern density of the touch pattern portion.

[0314] In one embodiment, the pixel light-emitting group 32 includes a first light-emitting unit 31a, a second light-emitting unit 31b and two third light-emitting units 31c; in the same pixel light-emitting group 32, the center lines connecting the first light-emitting unit 31a, the second light-emitting unit 31b and the third light-emitting unit 31c form a virtual quadrilateral.

[0315] In one embodiment, multiple pixel light-emitting groups 32 are arranged in rows along a first direction X and in columns along a second direction Y intersecting the first direction X. Within the same pixel light-emitting group 32, the first light-emitting unit 31a and the second light-emitting unit 31b are arranged at intervals along the second direction Y, and the two third light-emitting units 31c are arranged at intervals along the first direction X. Two first openings 24a are defined within the pixel light-emitting group 32, located on opposite sides of the first light-emitting unit 31a along the first direction X. This arrangement helps ensure good light transmittance in the light-transmitting area while also reducing the possibility of radio frequency interference and signal crosstalk.

[0316] In one embodiment, a second first opening 24b is further provided in the pixel light emitting group 32, and the second first opening 24b is provided between the two third light emitting units 31c. In this way, the light transmission performance of the light transmission area can be further improved.

[0317] In one embodiment, two adjacent touch sub-patterns 1231 share adjacent edges, which is beneficial for reducing the pattern density of the touch pattern portion.

[0318] In the case of using “including,” “having,” and “comprising” described herein, another component may be added unless a clear limiting term such as “only,” “consisting of,” etc. is used.
