[0131] Organic Light Emitting Diode (OLED) display technology is considered the most promising next-generation flat panel display technology. Compared with liquid crystal display technology, OLED display technology has advantages such as low energy consumption, low cost, self-emissiveness, wide viewing angle, and fast response speed.

[0132] In the process of developing this application, the inventors discovered the following problems in the related technology: The display panel may include a substrate and a cathode layer disposed on the substrate, a plurality of touch electrodes and a plurality of touch leads, the touch electrodes and touch leads are disposed in a one-to-one correspondence, each touch electrode includes a plurality of touch electrode portions, the plurality of touch electrode portions are spaced apart along the column direction, there is a gap between two adjacent touch electrode portions, in the corresponding touch electrode and touch lead, the touch lead includes a contact portion that contacts the touch electrode portion, the contact portion extends along the column direction, the middle part of the plurality of touch electrode portions of the touch electrode along the row direction is connected to the contact portion, and the touch lead divides the same gap into a first gap and a second gap. The cathode layer includes multiple cathode portions, which are correspondingly disposed with multiple touch electrodes. Each cathode portion includes a first connecting portion, a second connecting portion, multiple first sub-electrode portions, and multiple second sub-electrode portions. The first sub-electrode portions and second sub-electrode portions are respectively located on both sides of the contact portion. The first sub-electrode portions are correspondingly disposed with a first gap. The orthographic projection of the first sub-electrode portion on the substrate overlaps with the orthographic projection of the first gap on the substrate. The first sub-electrode portion is correspondingly disposed with a second gap. The orthographic projection of the second sub-electrode portion on the substrate overlaps with the orthographic projection of the second gap on the substrate. The first connecting portion is connected to the end of each first sub-electrode portion away from the contact portion to provide a cathode potential to each first sub-electrode portion through the first connecting portion. The second connecting portion is connected to the end of each second sub-electrode portion away from the contact portion to provide a cathode potential to each second sub-electrode portion through the second connecting portion. The orthographic projections of the first connecting portion and the second connecting portion on the substrate are located on both sides of the orthographic projection of the touch electrode on the substrate along the row direction, such that the orthographic projections of the first connecting portion and the second connecting portion on the substrate are disposed between the orthographic projections of two adjacent touch electrodes along the row direction.

[0133] However, the first connecting part provides a cathode potential to each corresponding first sub-electrode part, and the second connecting part provides a cathode potential to each corresponding second sub-electrode part. The number of first and second sub-electrode parts is relatively large, resulting in a large total current on the first and second connecting parts. In order to reduce the voltage drop on the first and second connecting parts, the dimensions of the first and second connecting parts along the row direction need to be set to be large, which leads to a large distance between two adjacent touch electrode parts along the row direction, resulting in a large touch blind area, which reduces the touch accuracy of the display panel and affects the touch performance of the display panel.

[0134] In view of at least one of the above problems, embodiments of this application provide a display panel and a display device that can improve the touch accuracy and touch performance of the display panel.

[0135] The following will combine Figures 1-17 The display device provided in the embodiments of this application will be described.

[0136] This application provides a display device, which may include a display panel 100. The display device may be an electronic paper device, mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, smart bracelet, smartwatch, supercomputer, navigator, wireless device, personal digital assistant (PDA), handheld or portable computer, GPS receiver / navigator, camera, MP4 video player, camcorder, game console, clock, calculator, television monitor, computer monitor, automotive display (e.g., odometer display), cockpit controller and / or display, camera view display (e.g., display of a rearview camera in a vehicle), electronic billboard or sign, projector, and other mobile or fixed terminals.

[0137] For example, the display panel 100 can be an organic light-emitting diode (OLED) display panel, a micro organic light-emitting diode (Micro OLED) display panel, a light-emitting diode (LED) display panel, a quantum dot light-emitting diode (QLED) display panel, a mini light-emitting diode (MiniLED) display panel, a micro light-emitting diode (Micro LED) display panel, or a liquid crystal display (LCD) display panel, etc. This application uses an OLED display panel as an example for illustration.

[0138] See Figure 1 and Figure 2The display panel 100 may have a first direction A, a second direction B, and a third direction C, all of which are different. The first direction A and the second direction B can be any two different directions parallel to the display panel 100, and the third direction C can be any direction intersecting a plane parallel to the display panel 100. For example, the first direction A, the second direction B, and the third direction C can be mutually perpendicular. Exemplarily, the first direction A can be the length direction of the display panel 100, the second direction B can be the width direction of the display panel 100, and the third direction C can be the thickness direction of the display panel 100. The length, width, and thickness in the embodiments of this application are merely for descriptive convenience and do not imply any limitation on the dimensions. For example, the width can be greater than, equal to, or less than the length. The orientation of the display panel 100 can be consistent with the orientation of the film layers such as the substrate 104.

[0139] The display panel 100 provided in the embodiments of this application will be described below.

[0140] See Figure 1 This application provides a display panel 100, which may include a substrate 104. The substrate 104 may provide support for other film layers subsequently applied.

[0141] See Figure 1 The display panel 100 may include a light-emitting functional layer 130, which is disposed on one side of the substrate 104. The light-emitting functional layer 130 includes a second electrode layer 132, a light-emitting layer 133 and a first electrode layer 131 disposed sequentially along the direction away from the substrate 104.

[0142] For example, the light-emitting layer 133 includes a plurality of light-emitting units 1331. The plurality of light-emitting units 1331 may be arranged in an array or spaced apart.

[0143] For example, the second electrode layer 132 may include a plurality of second electrodes, which may be arranged at intervals.

[0144] For example, one of the first electrode layer 131 and the second electrode layer 132 can be an anode, and the other of the first electrode layer 131 and the second electrode layer 132 can be a cathode. This application embodiment uses the second electrode layer 132 as the anode and the first electrode layer 131 as the cathode as an example for illustration.

[0145] For example, the first electrode layer 131 can be electrically connected to a first power line, which provides a first potential. The second electrode layer 132 can be electrically connected to a pixel driving circuit, which can be electrically connected to a second power line, which provides a second potential. One of the first and second power lines is used to transmit a high voltage, and the other is used to transmit a low voltage. For example, the first power line is used to transmit a low voltage (i.e., the first potential), and the second power line is used to transmit a high voltage (i.e., the second potential).

[0146] For example, the light-emitting functional layer 130 may also include one or more of the following: 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).

[0147] For example, the plurality of light-emitting units 1331 includes, but is not limited to, red light-emitting units, green light-emitting units, and blue light-emitting units. In other examples, the plurality of light-emitting units 1331 may also include white light-emitting units.

[0148] See Figure 1 and Figure 2 The display panel 100 may include a plurality of touch electrodes 140 and a plurality of touch leads 150. The plurality of touch electrodes 140 are spaced apart on one side of the substrate 104, and the touch electrodes 140 can realize the touch function of the display panel 100. The plurality of touch leads 150 are correspondingly arranged with the plurality of touch electrodes 140, and the touch leads 150 are used to connect the corresponding touch electrodes 140 to the touch chip 105.

[0149] See Figure 3In the same touch electrode 140, the touch electrode 140 includes a plurality of touch electrode portions 141, which are arranged at intervals along a second direction B, with a second interval 162 between adjacent touch electrode portions 141. Two touch electrodes 140 arranged adjacently along a first direction A have a first interval 161 between them. At least a portion of the touch leads 150 extend along the second direction B, and at least a portion of the touch leads 150 may be located within the first interval 161. The touch leads 150 are connected to corresponding ends of the plurality of touch electrode portions 141 of the corresponding touch electrode 140, which means that the touch leads 150 are all connected to the same end of the plurality of touch electrode portions 141 of the corresponding touch electrode 140 along the first direction A. Thus, by arranging multiple touch electrode portions 141 of the same touch electrode 140 at intervals along the second direction B, and connecting the touch lead 150 to the corresponding ends of the multiple touch electrode portions 141 of the corresponding touch electrode 140, the situation of reduced touch accuracy caused by arranging multiple touch electrode portions 141 of the same touch electrode 140 at intervals along the first direction A and connecting the touch lead 150 to the middle of the multiple touch electrode portions 141 of the corresponding touch electrode 140 along the second direction B can be avoided. This improves the touch accuracy and touch performance of the display panel 100. In addition, it also helps to alleviate the phenomenon of uneven display of the display panel 100.

[0150] In this embodiment, the correspondence between A and B can refer to one A corresponding to at least one B, or one B corresponding to at least one A. This embodiment primarily uses the example of one A corresponding to one B for illustration. For instance, the correspondence between touch lead 150 and touch electrode 140 can refer to one touch lead 150 and at least one touch electrode 140 corresponding, or one touch electrode 140 and at least one touch lead 150 corresponding.

[0151] For example, at least a portion of the touch lead 150 and the touch electrode 140 are disposed in the same layer, which facilitates the simultaneous fabrication of the at least a portion of the touch lead 150 and the touch electrode 140, and helps to simplify the fabrication process of the at least a portion of the touch lead 150 and the touch electrode 140, thereby reducing the fabrication cost.

[0152] In some embodiments, the orthographic projection of the touch electrode 140 on the substrate 104 corresponds to the interval between the orthographic projections of adjacent light-emitting units 1331 on the substrate 104. This is equivalent to the orthographic projection of the touch electrode 140 on the substrate 104 overlapping with the interval between the orthographic projections of two adjacent light-emitting units 1331 on the substrate 104, which helps to reduce the occlusion of the light-emitting unit 1331 by the touch electrode 140 and improve the light emission rate of the display panel 100.

[0153] It should be noted that the "overlapping" of the orthographic projection of the touch electrode 140 on the substrate 104 with the orthographic projection of the two adjacent light-emitting units 1331 on the substrate 104 can mean that the orthographic projection of the touch electrode 140 on the substrate 104 with the orthographic projection of the two adjacent light-emitting units 1331 on the substrate 104 "partially overlaps or completely overlaps".

[0154] In some embodiments, see Figure 3The first electrode layer 131 includes a plurality of first electrode portions 1311, which are correspondingly disposed with the touch electrodes 140. Each first electrode portion 1311 includes a first sub-electrode portion 1311a and a plurality of second sub-electrode portions 1311b. The first sub-electrode portion 1311a extends along a second direction B, and the plurality of second sub-electrode portions 1311b are spaced apart along the second direction B. In the corresponding first electrode portion 1311 and touch electrode 140, the second sub-electrode portions 1311b are correspondingly disposed with a second interval 162 of the touch electrode 140, and the orthographic projection of the second sub-electrode portion 1311b on the substrate 104 overlaps with the orthographic projection of the corresponding second interval 162 on the substrate 104. Both the first electrode portion 1311 and the touch electrode 140 can be formed of conductive material layers. During the fabrication of the first electrode portion 1311 and the touch electrode 140, a conductive material layer is formed on the side of the light-emitting layer 133 and the first isolation structure 191 away from the substrate 104. Since the first isolation structure 191 has an undercut structure, the conductive material layer on the side of the first isolation structure 191 away from the substrate 104 is separated from the conductive material layer in other areas, so that the conductive material layer on the first isolation structure 191 forms the touch electrode 140, and at least a portion of the conductive material layer in other areas forms the first electrode portion 1311. Therefore, the orthographic projection shape of the first electrode portion 1311 on the substrate 104 and the orthographic projection shape of the touch electrode 140 on the substrate 104 are approximately complementary. Along the first direction A, the first sub-electrode portion 1311a is located at the end of the corresponding touch electrode 140 opposite to the corresponding touch lead 150. The first sub-electrode portion 1311a is connected to the ends of multiple second sub-electrodes 1311b opposite to the corresponding touch leads 150, so as to provide a first potential to the multiple second sub-electrodes 1311b through the first sub-electrode portion 1311a. Correspondingly, the orthographic projection of the first sub-electrode portion 1311a on the substrate 104 is a third orthographic projection, the orthographic projection of the second sub-electrode portion 1311b on the substrate 104 is a fourth orthographic projection, and the orthographic projection of the touch lead 150 on the substrate 104 is a fifth orthographic projection. The third orthographic projection and the ends of the multiple fourth orthographic projections opposite to the corresponding fifth orthographic projections are all connected. Thus, by connecting the multiple touch electrode portions 141 of the corresponding touch electrode 140 to the same end along the first direction A via the touch lead 150, the first sub-electrode portion 1311a can be provided only at the end of the touch electrode 140 away from the corresponding touch lead 150 along the first direction A. It is not necessary to provide a structure to supply the first potential to multiple second sub-electrode portions 1311b on both sides of the touch electrode 140 along the second direction B. This makes the distance between two adjacent touch electrodes 140 along the second direction B smaller, which can reduce the touch blind zone and improve the touch accuracy of the display panel 100.

[0155] In some embodiments, at least partially adjacent first electrode portions 1311a along the second direction B are connected to each other, thereby connecting the two adjacent first electrode portions 1311 along the second direction B so as to simultaneously provide a first potential to all the second sub-electrode portions 1311b of the two adjacent first electrode portions 1311 along the second direction B.

[0156] In some embodiments, among the plurality of touch electrodes 140 arranged along the second direction B, at least partially adjacent two touch electrodes 140 are separated by a minimum distance L1 along the second direction B. Figure 4 ), equal to the minimum distance L2 between two adjacent touch electrode portions 141 in the same touch electrode 140 along the second direction B. Figure 4 In this case, it is not necessary to set virtual electrodes between at least two adjacent touch electrodes 140. The display of the area between at least two adjacent touch electrodes 140 and the area where at least two adjacent touch electrodes 140 are located is more consistent. This helps to reduce the setting of virtual electrodes, makes the distance between at least two adjacent touch electrodes 140 smaller, reduces touch blind spots, and helps to improve the touch accuracy of the display panel 100.

[0157] In some embodiments, see Figure 2 The display panel 100 may include a display area 100a and a non-display area 100b. The display area 100a can be used to display an image, and the non-display area 100b can be arranged adjacent to the display area 100a. The non-display area 100b can be located on at least one side of the display area 100a. For example, the non-display area 100b can surround the outer perimeter of the display area 100a, and the non-display area 100b can form a "black border" around the outer perimeter of the display area 100a.

[0158] For example, multiple touch electrodes 140 and multiple touch leads 150 can all be located in the display area 100a, and the touch leads 150 can also extend into the non-display area 100b. The display panel 100 includes multiple conductive lines 107, which are correspondingly arranged with the multiple touch leads 150, and the touch leads 150 are connected to the touch chip 105 through the corresponding conductive lines 107.

[0159] In some embodiments, the display panel 100 includes a touch chip 105 and a flexible circuit board 106. The touch chip 105 is located in the non-display area 100b of the display panel 100, and the flexible circuit board 106 is located on the side of the touch chip 105 opposite to the touch electrode 140.

[0160] In some embodiments, see Figure 3The display panel 100 includes a plurality of touch electrode rows 140a, each touch electrode row 140a including a plurality of touch electrodes 140 arranged along a second direction B, and the plurality of touch electrode rows 140a arranged along a first direction A. The touch electrode rows 140a are the plurality of touch electrodes 140 arranged in a row along the second direction B.

[0161] In some embodiments, see Figure 3 The display panel 100 includes a plurality of touch electrode columns 140b, each touch electrode column 140b including a plurality of touch electrodes 140 arranged along a first direction A, and the plurality of touch electrode columns 140b arranged along a second direction B. The touch electrode column 140b is a plurality of touch electrodes 140 arranged in a row along the first direction A.

[0162] In some embodiments, see Figure 3 In the touch electrode row 140a and the corresponding touch lead 150, the touch lead 150 is located on one side of the touch electrode row 140a along the first direction A. The first sub-electrode portions 1311a of the plurality of first electrode portions 1311 corresponding to the touch electrode row 140a are all located on the side of the touch electrode row 140a away from the touch lead 150. The first sub-electrode portions 1311a of the plurality of first electrode portions 1311 can be connected to each other, so that the plurality of first electrode portions 1311 are connected to provide a first potential to all the second sub-electrode portions 1311b of the plurality of first electrode portions 1311 at the same time. Therefore, it is not necessary to set a structure to provide a first potential to the plurality of second sub-electrode portions 1311b on both sides of the touch electrode 140 of the touch electrode row 140a along the second direction B. This makes the distance between two adjacent touch electrodes 140 of the touch electrode row 140a along the second direction B smaller, which can reduce the touch blind zone and improve the touch accuracy of the display panel 100.

[0163] In some embodiments, see Figure 6 In the two adjacent touch electrodes 140 along the second direction B, the two touch electrodes 140 are arranged opposite each other along the second direction B, so that the arrangement of the two adjacent touch electrodes 140 is more regular, which helps to reduce the difficulty of setting up the two adjacent touch electrodes 140.

[0164] In other embodiments, see Figure 7 In the two adjacent touch electrodes 140 along the second direction B, the two touch electrodes 140 are partially opposite to each other along the second direction B, and partially misaligned.

[0165] The touch electrode assembly 140c provided in the embodiments of this application will be described below.

[0166] In some embodiments, see Figure 3The display panel 100 includes multiple touch electrode groups 140c, each touch electrode group 140c including two touch electrodes 140 arranged along a first direction A, and the touch leads 150 corresponding to the two touch electrodes 140c are electrically connected. In other words, in the touch electrode group 140c and the corresponding two touch leads 150, the two touch leads 150 are connected to the same conductive line 107 and connected to the touch chip 105 through the same conductive line 107, thereby helping to reduce the load on a single touch electrode 140.

[0167] For example, in the touch electrode group 140c and the corresponding touch lead 150, the touch lead 150 is located between the two touch electrodes 140 of the touch electrode group 140c, so that the distance between the two touch leads 150 corresponding to the touch electrode group 140c is relatively close, which helps to reduce the difficulty of connecting the two touch leads 150 corresponding to the touch electrode group 140c to the same conductive line 107. In addition, in the touch electrode group 140c and the corresponding two first electrode portions 1311, the first sub-electrode portions 1311a of the two first electrode portions 1311 are respectively located on both sides of the touch electrode group 140c along the first direction A, so that there is no need to set the first sub-electrode portion 1311a for providing the first potential between the two touch electrodes 140 of the touch electrode group 140c, so that the distance between the two touch electrode portions 141 of the touch electrode group 140c is relatively close, which can reduce the touch blind zone and improve the touch accuracy.

[0168] For example, multiple touch electrode groups 140c arranged along the second direction B form a touch electrode group row 140d, and there are multiple touch electrode group rows 140d, which are arranged at intervals along the first direction A.

[0169] The touch lead 150 provided in the embodiments of this application will be described below.

[0170] In some embodiments, the orthographic projections of the plurality of touch leads 150 on the substrate 104 do not overlap, thereby avoiding contact between two adjacent touch leads 150.

[0171] In some embodiments, see Figure 6 The touch lead 150 includes a first sub-touch lead 151, which is in contact with the corresponding touch electrode 140. The first sub-touch lead 151 can connect the same end of multiple touch electrode portions 141 of the corresponding touch electrode 140.

[0172] For example, the first sub-touch lead 151 can extend along the second direction B, thereby making the shape of the first sub-touch lead 151 relatively simple, which helps to reduce the difficulty of fabricating the first sub-touch lead 151.

[0173] In some embodiments, see Figure 6 The touch lead 150 includes a second sub-touch lead 152, which extends along the second direction B in a direction away from the corresponding touch electrode 140, and is connected to the corresponding conductive line 107.

[0174] In some embodiments, see Figure 6 The touch lead 150 includes a third sub-touch lead 153, which is located between the first sub-touch lead 151 and the third sub-touch lead 153. At least part of the third sub-touch lead 153 extends in a different direction than the first sub-touch lead 151 and the second sub-touch lead 152. The first sub-touch lead 151 and the second sub-touch lead 152 are connected by the third sub-touch lead 153, which helps the touch lead 150 to avoid adjacent touch electrodes 140 or other touch leads 150.

[0175] For example, see Figure 6 The third sub-touch lead 153 extends along the first direction A, thereby making the shape of the third sub-touch lead 153 relatively simple, which helps to reduce the difficulty of manufacturing the third sub-touch lead 153.

[0176] For example, see Figure 7 The third sub-touch lead 153 includes alternating first sub-lines 1531 and second sub-lines 1532 connected end-to-end. The first sub-line 1531 extends along a first direction A, and the second sub-line 1532 extends along a second direction B. By setting the first sub-lines 1531 and second sub-lines 1532, the third sub-touch lead 153 can be bent more flexibly, allowing the touch lead 150 to be adapted to various arrangements of the touch electrodes 140. While avoiding adjacent touch electrodes 140 and other touch leads 150, the third sub-touch lead 153 is placed close to adjacent touch electrodes 140 and other touch leads 150, which helps to increase the density of touch electrodes 140 and touch leads 150, reduces touch blind spots, and improves touch accuracy. For example, see Figure 7 The number of first sub-lines 1531 can be two, and the number of second sub-lines 1532 can be one.

[0177] In some embodiments, in the same row of touch electrodes 140a, the number of touch electrodes 140 is odd, and the plurality of touch electrodes 140 includes a middle touch electrode located in the middle. The non-display area 100b includes a first non-display area and a second non-display area located on both sides of the second direction B. The touch leads 150 corresponding to the plurality of touch electrodes 140 located between the middle touch electrode and the first non-display area can all extend to the first non-display area. The touch leads 150 corresponding to the plurality of touch electrodes 140 located between the middle touch electrode and the second non-display area can all extend to the second non-display area. The touch lead 150 corresponding to the middle touch electrode can extend to either the first non-display area or the second non-display area.

[0178] In other embodiments, in the same row of touch electrodes 140a, the number of touch electrodes 140 is even, the display panel 100 has a center line extending along a first direction A, and the touch leads 150 corresponding to the plurality of touch electrodes 140 located between the center line and the first non-display area can all extend to the first non-display area, and the touch leads 150 corresponding to the plurality of touch electrodes 140 located between the center line and the second non-display area can all extend to the second non-display area.

[0179] In other embodiments, in the same row of touch electrodes 140a, the touch leads 150 corresponding to multiple touch electrodes 140 can all extend to the first non-display area or the second non-display area.

[0180] The second interval 162 provided in the embodiments of this application will be described below.

[0181] In some embodiments, see Figure 3 and, Figure 8a , Figure 8b The second interval 162 includes a plurality of first openings 171 and a first gap 181. The plurality of first openings 171 are arranged at intervals along a first direction A, and adjacent first openings 171 are connected by the first gap 181. The first openings 171 are correspondingly disposed with the light-emitting unit 1331. The orthographic projection of the light-emitting unit 1331 on the substrate 104 overlaps with the orthographic projection of the corresponding first opening 171 on the substrate 104, so that the light from the light-emitting unit 1331 can be emitted through the first opening 171, which helps to reduce the influence of the touch electrode 140 on the light emission of the light-emitting unit 1331.

[0182] For example, the number of light-emitting units 1331 corresponding to any one first opening 171 can be at least one. For instance, the number of light-emitting units 1331 corresponding to any one first opening 171 can be 1, 2, 3, 4, or any number greater than or equal to 5. The number of light-emitting units 1331 corresponding to any two first openings 171 can be the same or different.

[0183] For example, at least a portion of the first opening 171 is configured to correspond to at least two light-emitting units 1331 arranged along the second direction B. See, for example, [link to relevant documentation]. Figure 8b At least a portion of the first opening 171 is correspondingly disposed to two light-emitting units 1331 arranged along the second direction B. See also... Figure 11 At least part of the first opening 171 is configured to correspond to the three light-emitting units 1331 arranged along the second direction B.

[0184] In some embodiments, see Figure 8b , Figure 10 and Figure 11 In two adjacent first openings 171 arranged along the first direction A, the number of light-emitting units 1331 corresponding to each first opening 171 is the same. Alternatively, see... Figure 12 In the two first openings 171 arranged adjacent to each other along the first direction A, the number of light-emitting units 1331 corresponding to each first opening 171 is different.

[0185] For example, see Figure 12 In the two first openings 171 arranged adjacent to each other along the first direction A, the number of light-emitting units 1331 corresponding to one first opening 171 is 1, and the number of light-emitting units 1331 corresponding to the other first opening 171 is 2.

[0186] In some embodiments, see Figure 8b and Figure 11 In the plurality of first gaps 181 between two adjacent touch electrode portions 141, the two adjacent first gaps 181 are staggered along the first direction A, thereby reducing the regularity of the distribution of the plurality of first gaps 181 in the same second interval 162, which helps to reduce the visibility of the first gaps 181, thereby reducing the visibility of the touch electrode 140 pattern, alleviating the bright and dark stripe phenomenon of the display panel 100, and improving the display effect of the display panel 100.

[0187] In some embodiments, see Figure 10 and Figure 12 In the plurality of first gaps 181 between two adjacent touch electrode portions 141, two adjacent first gaps 181 are arranged opposite each other along the first direction A, thereby reducing the difficulty of setting the first gaps 181. In addition, the shape of the orthographic projection of the second gap 162 on the substrate 104 is adapted to the shape of the orthographic projection of the corresponding second sub-electrode portion 1311b on the substrate 104. When two adjacent first gaps 181 are arranged opposite each other along the first direction A, it is beneficial to shorten the current transmission path of the second sub-electrode portion 1311b in the first direction A, which is beneficial to reduce the resistance of the second sub-electrode portion 1311b and reduce the voltage drop on the second sub-electrode portion 1311b.

[0188] For example, see Figure 10 and Figure 12 In the plurality of first gaps 181 between two adjacent touch electrode portions 141, each first gap 181 is arranged in a straight line. The shape of the orthographic projection of the second gap 162 on the substrate 104 is adapted to the shape of the orthographic projection of the corresponding second sub-electrode portion 1311b on the substrate 104. In this way, the current transmission path of the second sub-electrode portion 1311b in the first direction A can be shortened better, so as to better reduce the resistance of the second sub-electrode portion 1311b and better reduce the voltage drop on the second sub-electrode portion 1311b.

[0189] In some embodiments, the orthographic projection of any light-emitting unit 1331 on the substrate 104 can be opposite to the orthographic projection of the first gap 181 on the substrate 104 along the first direction A, or the orthographic projection of any light-emitting unit 1331 on the substrate 104 can be offset from the orthographic projection of the first gap 181 on the substrate 104 along the first direction A. For example, the orthographic projection of the first gap 181 on the substrate 104 is a first orthographic projection, and the orthographic projection of the light-emitting unit 1331 on the substrate 104 is a second orthographic projection. At least a portion of the second orthographic projections are correspondingly arranged with the first orthographic projections, and the second orthographic projections and their corresponding first orthographic projections are opposite to each other along the first direction A. The light emission effect of the light-emitting unit 1331 corresponding to the first gap 181 is different from the light emission effect of the light-emitting unit 1331 not corresponding to the first gap 181.

[0190] See Figure 8b The dashed box indicates the area where the pixel opening 211 corresponding to the light-emitting unit 1331 is located. R represents the red light-emitting unit, G represents the green light-emitting unit, and B represents the blue light-emitting unit.

[0191] In some embodiments, see Figure 11 In this configuration, all light-emitting units 1331 corresponding to the second orthogonal projection, which is positioned opposite to the first orthogonal projection, emit the same color. This means that all first gaps 181 are corresponding to multiple light-emitting units 1331 of the same color. This ensures that all first gaps 181 affect the light emission of light-emitting units 1331 of the same color, while having no effect on the light emission of light-emitting units 1331 of other colors. This results in a more consistent light emission effect of the first gaps 181 across different areas, thereby improving the display uniformity of the display panel 100. For example, all light-emitting units 1331 corresponding to the second orthogonal projection, which is positioned opposite to the first orthogonal projection, emit red, green, or blue light.

[0192] In other embodiments, see Figure 8b and Figure 10Among all the light-emitting units 1331 corresponding to the second orthogonal projection that is set opposite to the first orthogonal projection, at least a portion of the light-emitting units 1331 emit different colors, thereby avoiding the display panel 100 from having color shift due to all the first gaps 181 affecting the light emission of the light-emitting units 1331 of the same color.

[0193] In some embodiments, see Figure 8b The second orthographic projection, which is positioned opposite to the first orthographic projection, includes a first light-emitting unit, a second light-emitting unit, and a third light-emitting unit. The first light-emitting unit, the second light-emitting unit, and the third light-emitting unit emit different colors. This results in some first gaps 181 being positioned in relation to the first light-emitting unit, some first gaps 181 being positioned in relation to the second light-emitting unit, and some first gaps 181 being positioned in relation to the third light-emitting unit. The light emitted by the first light-emitting unit, the second light-emitting unit, and the third light-emitting unit is affected by the first gaps 181, thereby further mitigating the color shift of the display panel 100 caused by the first gaps 181.

[0194] In some embodiments, see Figure 8b In the same touch electrode section 141, the touch electrode section 141 includes a plurality of first extension sections 1411 and a plurality of first connecting sections 1421. The plurality of first extension sections 1411 are arranged at intervals along a first direction A. Adjacent first extension sections 1411 are connected by first connecting sections 1421. The extension directions of adjacent first extension sections 1411 and first connecting sections 1421 are different.

[0195] For example, the orthographic projection of the first extension 1411 on the substrate 104 is at least partially located between the orthographic projections of two adjacent light-emitting units 1331 disposed along the first direction A on the substrate 104, thereby reducing the light emission effect of the first extension 1411 on the light-emitting unit 1331 and improving the light emission rate of the display panel 100.

[0196] For example, the orthographic projection of the first connecting segment 1421 on the substrate 104 is at least partially located between the orthographic projections of two adjacent light-emitting units 1331 disposed along the second direction B on the substrate 104, thereby reducing the light emission effect of the first connecting segment 1421 on the light-emitting unit 1331 and improving the light emission rate of the display panel 100.

[0197] In some embodiments, see Figure 8bTwo adjacent touch electrode portions 141 are defined as a first touch electrode portion 141a and a second touch electrode portion 141b, respectively. The first extension segment 1411 of the first touch electrode portion 141a and the first extension segment 1411 of the second touch electrode portion 141b are correspondingly arranged. A first gap 181 exists between the first extension segment 1411 of the first touch electrode portion 141a and the corresponding first extension segment 1411 of the second touch electrode portion 141b. The first extension segment 1411 is disposed opposite to each other along the second direction B. The first connecting segment 1421 of the first touch electrode portion 141a and the first connecting segment 1421 of the second touch electrode portion 141b are disposed correspondingly. A first opening 171 is provided between the first connecting segment 1421 of the first touch electrode portion 141a and the first connecting segment 1421 of the corresponding second touch electrode portion 141b. The first connecting segment 1421 of the first touch electrode portion 141a and the first connecting segment 1421 of the corresponding second touch electrode portion 141b are disposed opposite to each other along the second direction B.

[0198] For example, the first extension segment 1411 extends along the second direction B.

[0199] For example, the first connecting segment 1421 extends along the first direction A.

[0200] In some embodiments, see Figure 12 In the same touch electrode portion 141, in at least two adjacent first extension segments 1411, the same end of each first extension segment 1411 along the second direction B is connected to the first connecting segment 1421.

[0201] In some embodiments, see Figure 11 The first extension segment 1411 includes a first sub-extension segment 1411a, a second sub-extension segment 1411b, and a third sub-extension segment 1411c arranged sequentially along the second direction B. In the same touch electrode portion 141, the second sub-extension segments 1411b of two adjacent first extension segments 1411 are connected to the first connecting segment 1421.

[0202] For example, the extension length of the first sub-extension segment 1411a along the second direction B and the extension length of the third sub-extension segment 1411c along the second direction B may be different or the same, and the embodiments of this application do not limit this.

[0203] The virtual electrodes provided in the embodiments of this application will be described below.

[0204] In some embodiments, see Figure 4The display panel 100 includes multiple virtual electrodes (multiple first virtual electrodes 110 and / or multiple second virtual electrodes 120 and / or multiple third virtual electrodes 230). The virtual electrodes are insulated from the touch electrodes 140 and the first electrode layer 131. By setting virtual electrodes, the display of the display panel 100 in the area where the touch electrodes 140 are set and the area where the virtual electrodes are set can be made more consistent, thereby improving the display uniformity of the display panel 100.

[0205] In some embodiments, see Figure 4 The multiple virtual electrodes may include multiple first virtual electrodes 110. The first virtual electrodes 110 are disposed on one side of the substrate 104, and at least a portion of two adjacent touch electrode rows 140a are provided with first virtual electrodes 110.

[0206] For example, in the touch electrode row 140a and the corresponding touch lead 150, the touch lead 150 is located on one side of the touch electrode row 140a along the first direction A, the first virtual electrode 110 is correspondingly disposed with the touch electrode row 140a, and the first virtual electrode 110 is located on the other side of the corresponding touch electrode row 140a along the first direction A.

[0207] See Figure 3 In the embodiment with touch electrode group 140c, the first virtual electrode 110 is located on both sides of the touch electrode group 140c along the first direction A. Thus, the first virtual electrode 110 is not placed between the two touch electrodes 140 of the touch electrode group 140c, reducing the number of first virtual electrodes 110 and improving touch accuracy. In the embodiment with touch electrode group row 140d, the first virtual electrode 110 is disposed on both sides of the touch electrode group row 140d along the first direction A.

[0208] In some embodiments, the first virtual electrode 110 and the touch electrode 140 are disposed in the same layer and made of the same material, which can simplify the manufacturing process of the first virtual electrode 110 and the touch electrode 140 and reduce the manufacturing cost of the display panel 100.

[0209] It should be noted that "same layer, same material" in the embodiments of this application refers to forming a base film layer from the same material, and then, after patterning and / or other processing of the base film layer, forming various structural film layers from different parts of the base film layer. The processing processes for the different structural film layers can be the same or different, and the different structural film layers can have the same or different thicknesses, and can also be on the same horizontal plane or different horizontal planes.

[0210] In some embodiments, see Figure 3In the same first virtual electrode 110, the first virtual electrode 110 includes a plurality of first virtual electrode portions 110a, which are arranged at intervals along a first direction A, and a third interval 163 is provided between two adjacent first virtual electrode portions 110a. The first electrode layer 131 includes a plurality of second electrode portions 1312, which are correspondingly disposed with the first virtual electrode 110. The second electrode portions 1312 are connected to a first potential, and the second electrode portions 1312 are connected to the first sub-electrode portions 1311a of the adjacent first electrode portions 1311, thereby providing the first potential to the first sub-electrode portions 1311a and the second sub-electrode portions 1311b of the first electrode portions 1311 in sequence through the second electrode portions 1312.

[0211] For example, see Figure 3 In the correspondingly configured second electrode portion 1312 and first virtual electrode 110, the second electrode portion 1312 includes a plurality of third sub-electrode portions 1312c. The third sub-electrode portions 1312c are correspondingly configured with the third interval 163. The orthographic projection of the third sub-electrode portion 1312c on the substrate 104 overlaps with the orthographic projection of the third interval 163 on the substrate 104. The plurality of third sub-electrode portions 1312c are connected, thereby connecting the second electrode portion 1312 into a whole, which is beneficial to reduce the resistance on the second electrode portion 1312 and reduce the voltage drop on the second electrode portion 1312.

[0212] For example, the shape of the orthographic projection of the third sub-electrode portion 1312c on the substrate 104 is adapted to the shape of the orthographic projection of the third interval 163 on the substrate 104.

[0213] For example, the orthographic projection of the first virtual electrode 110 on the substrate 104 and the orthographic projection of the light-emitting unit 1331 on the substrate 104 are spaced apart, which helps to reduce the occlusion of the light-emitting unit 1331 by the first virtual electrode 110 and improves the light emission rate of the display panel 100.

[0214] In some embodiments, see Figure 3In the same first virtual electrode section 110a, the first virtual electrode section 110a includes a plurality of first sub-sections 111 arranged at intervals along the second direction B, and a first auxiliary gap 1871 is provided between two adjacent first sub-sections 111. In the correspondingly provided second electrode section 1312 and first virtual electrode 110, the second electrode section 1312 includes a fourth sub-electrode section 1312d, the fourth sub-electrode section 1312d is correspondingly provided with the first auxiliary gap 1871, the orthographic projection of the fourth sub-electrode section 1312d on the substrate 104 overlaps with the orthographic projection of the first auxiliary gap 1871 on the substrate 104, and two adjacent third sub-electrode sections 1312c are connected by the fourth sub-electrode section 1312d located between the two adjacent third sub-electrode sections 1312c, thereby connecting the second electrode section 1312 into a whole.

[0215] For example, the shape of the orthographic projection of the fourth sub-electrode portion 1312d on the substrate 104 is adapted to the shape of the orthographic projection of the first auxiliary gap 1871 on the substrate 104.

[0216] In some embodiments, see Figure 3 In two adjacent first virtual electrode sections 110a, the first auxiliary gap 1871 of one first virtual electrode section 110a and the first auxiliary gap 1871 of the other first virtual electrode section 110a are arranged opposite to each other along the first direction A, so that the arrangement of the first auxiliary gap 1871 is more regular, which helps to reduce the difficulty of setting the first auxiliary gap 1871.

[0217] In some embodiments, see Figure 3 , Figure 13 and Figure 1 5. Within the same first sub-part 111, the first sub-part 111 includes a second extension segment 1112. The second extension segment 1112 extends along the second direction B. The shape of the second extension segment 1112 is relatively simple, which helps to reduce the difficulty of setting the second extension segment 1112. For example, see... Figure 15 The first sub-section 111 is entirely formed by the second extension 1112. Alternatively, see [link to other documentation]. Figure 13 The first sub-part 111 is formed by the second extension 1112.

[0218] See Figure 15In the embodiment where the first sub-part 111 is entirely formed by the second extension 1112, the dimension of the third interval 163 along the first direction A is the same everywhere along the second direction B, thereby reducing the manufacturing difficulty and cost of the third interval 163. In addition, the shape of the orthographic projection of the third sub-electrode 1312c on the substrate 104 is adapted to the shape of the orthographic projection of the third interval 163 on the substrate 104. Thus, the shape of the third sub-electrode 1312c is simpler, and the width (i.e., the dimension along the first direction A) of the third sub-electrode 1312c is larger at all points, which is beneficial to reduce the resistance and voltage drop of the third sub-electrode 1312c.

[0219] In some embodiments, see Figure 13 Within the same first sub-section 111, the first sub-section 111 includes a plurality of second connecting segments 1122 connected to the second extension 1112. On the same side of the second extension 1112 along the first direction A, the plurality of second connecting segments 1122 are arranged at intervals along the second direction B. By setting the second connecting segments 1122, the morphology of the first virtual electrode 110 and the touch electrode 140 are made more similar, which can further improve the display uniformity of the display panel 100 in the area where the first virtual electrode 110 is located and the area where the touch electrode 140 is located.

[0220] For example, the orthographic projection of the second extension 1112 on the substrate 104 is at least partially located between the orthographic projections of two adjacent light-emitting units 1331 along the first direction A on the substrate 104, thereby reducing the light emission effect of the second extension 1112 on the light-emitting unit 1331 and improving the light emission rate of the display panel 100.

[0221] For example, the orthographic projection of the second connecting segment 1122 on the substrate 104 is at least partially located between the orthographic projections of two adjacent light-emitting units 1331 along the second direction B on the substrate 104, thereby reducing the light emission effect of the second connecting segment 1122 on the light-emitting unit 1331 and improving the light emission rate of the display panel 100.

[0222] In some embodiments, see Figure 13 The third interval 163 includes a plurality of second openings 172 and a second gap 182. The plurality of second openings 172 are arranged at intervals along the second direction B, and adjacent two second openings 172 are connected by the second gap 182. The second openings 172 are correspondingly disposed with the light-emitting unit 1331. The orthographic projection of the light-emitting unit 1331 on the substrate 104 overlaps with the orthographic projection of the corresponding second opening 172 on the substrate 104, and the light from the light-emitting unit 1331 can be emitted through the second openings 172.

[0223] In some embodiments, see Figure 13In two adjacent first sub-parts 111 along the first direction A, the second connecting segment 1122 of one first sub-part 111 is correspondingly provided with the second connecting segment 1122 of the other first sub-part 111. There is a second gap 182 between the second connecting segment 1122 of one first sub-part 111 and the corresponding second connecting segment 1122 of the other first sub-part 111. The second connecting segment 1122 of one first sub-part 111 and the corresponding second connecting segment 1122 of the other first sub-part 111 are arranged opposite to each other along the first direction A. There are multiple second openings 172 between the second extension segment 1112 of one first sub-part 111 and the second extension segment 1112 of the other first sub-part 111. The second extension segment 1112 of one first sub-part 111 and the second extension segment 1112 of the other first sub-part 111 are arranged opposite to each other along the first direction A.

[0224] In some embodiments, see Figure 5 The display panel 100 includes a second virtual electrode 120 disposed on one side of the substrate 104. There are multiple second virtual electrodes 120, with one second virtual electrode 120 disposed between two adjacent first virtual electrode portions 110a, thus reducing the number of second virtual electrodes 120 between adjacent first virtual electrode portions 110a. The multiple second virtual electrodes 120 are arranged along a first direction A to form a second virtual electrode column. There can be only one second virtual electrode column; thus, the number of second virtual electrode columns is reduced, which can decrease touch blind spots and reduce the impact of the second virtual electrode column on touch accuracy.

[0225] In some other embodiments, the display panel 100 may not have the second virtual electrode 120, which can further reduce the touch blind zone and further reduce the impact of the second virtual electrode 120 on touch accuracy.

[0226] In some embodiments, the number of touch electrode columns 140b is odd, and the multiple touch electrode columns 140b include adjacent first touch electrode columns and second touch electrode columns. The first touch electrode column is located in the middle of all touch electrode columns, and the second virtual electrode 120 is located between the first touch electrode column and the second touch electrode column. In this way, layout interference between the second virtual electrode 120 and the touch lead 150 can be avoided.

[0227] In other embodiments, the number of touch electrode columns 140b is even, and the multiple touch electrode columns 140b include adjacent third touch electrode columns and fourth touch electrode columns. The third touch electrode columns and fourth touch electrode columns are both located at the very center of all touch electrode columns 140b. The second virtual electrode 120 is located between the third touch electrode columns and the fourth touch electrode columns. In this way, layout interference between the second virtual electrode 120 and the touch lead 150 can be avoided.

[0228] In some embodiments, see Figure 5 The second virtual electrode 120 includes a plurality of second virtual electrode portions 120a, which are arranged at intervals along a second direction B. A fourth interval 164 exists between adjacent second virtual electrode portions 120a. The first electrode layer 131 includes a plurality of third electrode portions 1313, which are correspondingly disposed with respect to the second virtual electrode 120. In the correspondingly disposed third electrode portions 1313 and second virtual electrode 120, the third electrode portion 1313 includes a plurality of fifth sub-electrode portions 1313e, which are correspondingly disposed with respect to the fourth interval 164. The orthographic projection of the fifth sub-electrode portion 1313e on the substrate 104 overlaps with the orthographic projection of the fourth interval 164 on the substrate 104. The plurality of fifth sub-electrode portions 1313e are connected, thereby connecting the third electrode portion 1313 into a whole, which helps to reduce the resistance of the third electrode portion 1313 and reduce the voltage drop on the third electrode portion 1313.

[0229] For example, the shape of the orthographic projection of the fifth sub-electrode portion 1313e on the substrate 104 is adapted to the shape of the orthographic projection of the fourth interval 164 on the substrate 104.

[0230] In some embodiments, within the same second virtual electrode portion 120a, the second virtual electrode portion 120a includes a plurality of second sub-parts 122 spaced apart along a first direction A, with a second auxiliary gap 1872 between adjacent second sub-parts 122. The third electrode portion 1313 includes a sixth sub-electrode portion 1313f, which is correspondingly disposed with the second auxiliary gap 1872. The orthographic projection of the sixth sub-electrode portion 1313f on the substrate 104 overlaps with the orthographic projection of the second auxiliary gap 1872 on the substrate 104. Two adjacent fifth sub-electrode portions 1313e are connected by the sixth sub-electrode portion 1313f located between the two adjacent fifth sub-electrode portions 1313e, thereby connecting the third electrode portion 1313 into a whole.

[0231] For example, the shape of the orthographic projection of the sixth sub-electrode portion 1313f onto the substrate 104 is adapted to the shape of the orthographic projection of the second auxiliary gap 1872 onto the substrate 104.

[0232] In some embodiments, in two adjacent second virtual electrode portions 120a, the second auxiliary gap 1872 of one second virtual electrode portion 120a and the second auxiliary gap 1872 of the other second virtual electrode portion 120a are arranged opposite to each other along the second direction B, so that the arrangement of the second auxiliary gaps 1872 is more regular, which helps to reduce the difficulty of setting the second auxiliary gaps 1872.

[0233] In some embodiments, referring to the figures, adjacent second electrode portions 1312 and third electrode portions 1313 located between the two adjacent second electrode portions 1312 are connected. This allows all second electrode portions 1312 to be connected into a single unit via multiple third electrode portions 1313, which helps reduce the resistance of the second electrode portions 1312 and thus reduce the voltage drop of the second electrode portions 1312. Furthermore, since the second electrode portions 1312 are connected to an adjacent row of first electrode portions 1311, the first electrode portions 1311, second electrode portions 1312, and third electrode portions 1313 are connected into a single unit, which facilitates the connection of the first electrode layer 131 into a full-surface electrode.

[0234] It should be noted that when the second virtual electrode 120 is not provided, a third electrode portion 1313 can also be provided. A third electrode portion 1313 can be provided between adjacent second electrode portions 1312, and the adjacent second electrode portions 1312 and the third electrode portion 1313 located between the two adjacent second electrode portions 1312 are connected. In this case, the shape of the third electrode portion 1313 can be set to be simpler, and the size of the third electrode portion 1313 along the second direction B can be set to be smaller, which is beneficial to improving touch accuracy.

[0235] In some embodiments, see Figure 16 The fourth interval 164 includes a plurality of third openings 173 and a third gap 183. The plurality of third openings 173 are arranged at intervals along the first direction A, and adjacent third openings 173 are connected by a third gap 183. The third openings 173 are correspondingly disposed with the light-emitting unit 1331. The orthographic projection of the light-emitting unit 1331 on the substrate 104 overlaps with the orthographic projection of the corresponding third opening 173 on the substrate 104, and the light from the light-emitting unit 1331 can be emitted through the third opening 173.

[0236] In some embodiments, the orthographic projection of the second virtual electrode 120 on the substrate 104 and the orthographic projection of the light-emitting unit 1331 on the substrate 104 are spaced apart, thereby reducing the occlusion of the light-emitting unit 1331 by the second virtual electrode 120 and improving the light emission rate of the display panel 100.

[0237] In some embodiments, the second virtual electrode 120 and the touch electrode 140 are disposed in the same layer and made of the same material, which can simplify the manufacturing process of the second virtual electrode 120 and the touch electrode 140 and reduce the manufacturing cost of the display panel 100.

[0238] In some embodiments, see Figure 16In the same second sub-part 122, the second sub-part 122 includes a plurality of third extension segments 1223 and third connecting segments 1233. The plurality of third extension segments 1223 are arranged at intervals along a first direction A, and adjacent third extension segments 1223 are connected by third connecting segments 1233. The extension directions of adjacent third extension segments 1223 and third connecting segments 1233 are different.

[0239] For example, the third extension segment 1223 extends along the second direction B.

[0240] For example, the third connecting segment 1233 extends along the first direction A.

[0241] In some embodiments, the orthographic projection of the third extension 1223 on the substrate 104 is at least partially located between the orthographic projections of two adjacent light-emitting units 1331 along the first direction A on the substrate 104, thereby reducing the light emission effect of the third extension 1223 on the light-emitting unit 1331 and improving the light emission rate of the display panel 100.

[0242] In some embodiments, the orthographic projection of the third connecting segment 1233 on the substrate 104 is at least partially located between the orthographic projections of two adjacent light-emitting units 1331 along the second direction B on the substrate 104, thereby reducing the light emission effect of the third connecting segment 1233 on the light-emitting unit 1331 and improving the light emission rate of the display panel 100.

[0243] In some embodiments, in two adjacent second sub-parts 122 along the second direction B, the third connecting segment 1233 of one second sub-part 122 is correspondingly disposed with the third connecting segment 1233 of the other second sub-part 122, and a third opening 173 is provided between the third connecting segment 1233 of one second sub-part 122 and the corresponding third connecting segment 1233 of the other second sub-part 122, and the third connecting segment 1233 of one second sub-part 122 and the corresponding third connecting segment 1233 of the other second sub-part 122 are respectively disposed. 233 are arranged opposite each other along the second direction B, and the third extension segment 1223 of one second sub-part 122 is correspondingly arranged with the third extension segment 1223 of the other second sub-part 122. There is a third gap 183 between the third extension segment 1223 of one second sub-part 122 and the corresponding third extension segment 1223 of the other second sub-part 122. The third extension segment 1223 of one second sub-part 122 and the corresponding third extension segment 1223 of the other second sub-part 122 are arranged opposite each other along the second direction B.

[0244] See Figure 8aThe multiple virtual electrodes may include multiple third virtual electrodes 230. The third virtual electrodes 230 may be located on at least one side of the touch lead 150. For example, the third virtual electrode 230 may be located between two adjacent touch leads 150, thereby making the display of the display panel in the area between two adjacent touch leads 150 and the area where the touch electrode 140 is located more consistent, and improving the display uniformity of the display panel.

[0245] The isolation structure provided in the embodiments of this application will be described below.

[0246] In some embodiments, see Figure 1 and Figure 9 The display panel 100 includes at least one isolation structure (i.e., at least one of a first isolation structure 191, a second isolation structure 192, and a third isolation structure 193). The at least one isolation structure includes a first isolation structure 191. The touch electrode 140 is located on the side of the first isolation structure 191 away from the substrate 104. The first isolation structure 191 encloses and forms a plurality of fourth openings 174 and fourth gaps 184. Two adjacent fourth openings 174 along the first direction A are connected through the fourth gaps 184. The second sub-electrode portions 1311b of the first electrode portion 1311 are located in the fourth openings 174 and the fourth gaps 184. The second sub-electrode portions 1311b located in two adjacent fourth openings 174 along the first direction A are connected through the second sub-electrode portions 1311b located in the fourth gaps 184.

[0247] In some embodiments, the first electrode layer 131 and the touch electrode 140 are disposed on the same layer and made of the same material, thereby simplifying the fabrication process of the first electrode layer 131 and the touch electrode 140 and reducing the manufacturing cost of the display panel 100. In related technologies, when the touch adopts an on-cell structure, multiple layers need to be fabricated on the encapsulation layer to form the touch electrode. In the embodiments of this application, by disposing the touch electrode 140 and the first electrode layer 131 on the same layer and made of the same material, it is beneficial to reduce the number of film layers in the display panel 100, simplify the manufacturing process of the display panel 100, and reduce the thickness and cost of the display panel 100.

[0248] In some embodiments, the first isolation structure 191 may refer to an undercut structure that is larger at the top and smaller at the bottom, capable of separating the touch electrode 140 and the first electrode layer 131. The isolation structure may be a structure formed by a single film layer or a structure formed by stacking multiple film layers.

[0249] For example, the cross-sectional shape of the isolation structure can be an inverted trapezoid with a larger top and a smaller bottom, a "T" shape, or an "I" shape, etc.

[0250] In some embodiments, the touch electrode 140 and the first electrode layer 131 are separated by the first isolation structure 191. This allows the shape of the orthographic projection of the first isolation structure 191 onto the substrate 104 to be adapted to (e.g., identical to) the shape of the orthographic projection of the touch electrode 140 onto the substrate 104, so that the shape of the formed touch electrode 140 can be controlled by controlling the shape of the first isolation structure 191. Furthermore, since the second sub-electrode portion 1311b is located within the fourth opening 174 and the fourth gap 184, the shape of the fourth opening 174 and the fourth gap 184 can be controlled by controlling the shape of the first isolation structure 191, thereby controlling the shape of the second sub-electrode portion 1311b.

[0251] For example, see Figure 8b and Figure 9 The fourth opening 174 is provided corresponding to the first opening 171. The orthographic projection of the fourth opening 174 on the substrate 104 overlaps with the orthographic projection of the corresponding first opening 171 on the substrate 104 (e.g., completely coincides). The fourth gap 184 is provided corresponding to the first gap 181. The orthographic projection of the fourth gap 184 on the substrate 104 overlaps with the orthographic projection of the corresponding first gap 181 on the substrate 104 (e.g., completely coincides).

[0252] For example, see Figure 1 The first isolation structure 191 includes a first isolation portion 1911 and a second isolation portion 1912. The second isolation portion 1912 is disposed on the side of the first isolation portion 1911 facing the substrate 104. The orthographic projection of the second isolation portion 1912 on the substrate 104 is disposed within the orthographic projection of the first isolation portion 1911 on the substrate 104, thereby making the first isolation structure 191 form an undercut structure that is "larger at the top and smaller at the bottom", that is, the isolation structure has an "eaves". In this way, during the formation of the touch electrode 140 and the first electrode layer 131, the first isolation structure 191 can isolate the touch electrode 140 and the first electrode layer 131.

[0253] In some embodiments, at least one of the first isolation portion 1911 and the second isolation portion 1912 is made of an insulating material, thereby helping to prevent short circuit between the touch electrode 140 and the first electrode layer 131.

[0254] In some embodiments, see Figure 14 At least one isolation structure may include a second isolation structure 192, which is located between the substrate 104 and the first virtual electrode 110. By providing the second isolation structure 192, the first virtual electrode 110 and the first electrode layer 131 can be isolated.

[0255] For example, see Figure 14The second isolation structure 192 encloses and forms a connected fifth interval 165 and a third auxiliary gap 1873. The third sub-electrode 1312c of the second electrode portion 1312 is located in the fifth interval 165, and the fourth sub-electrode 1312d of the second electrode portion 1312 is located in the third auxiliary gap 1873. When there are multiple fifth intervals 165, the third sub-electrode 1312c in two adjacent fifth intervals 165 are connected through the fourth sub-electrode 1312d located in the third auxiliary gap 1873.

[0256] For example, see Figure 13 and Figure 14 The third interval 163 and the fifth interval 165 are correspondingly arranged, and the orthographic projection of the third interval 163 on the substrate 104 overlaps with the orthographic projection of the corresponding fifth interval 165 on the substrate 104. The first auxiliary gap 1871 and the third auxiliary gap 1873 are correspondingly arranged, and the orthographic projection of the first auxiliary gap 1871 on the substrate 104 overlaps with the orthographic projection of the corresponding third auxiliary gap 1873 on the substrate 104. For example, the orthographic projection of the third interval 163 on the substrate 104 completely coincides with the orthographic projection of the corresponding fifth interval 165 on the substrate 104, and the orthographic projection of the first auxiliary gap 1871 on the substrate 104 completely coincides with the orthographic projection of the corresponding third auxiliary gap 1873 on the substrate 104. By controlling the shape of the second isolation structure 192, the shapes of the fifth interval 165 and the third auxiliary gap 1873 are controlled, thereby controlling the shapes of the third interval 163 and the first auxiliary gap 1871, and controlling the shape of the second electrode portion 1312.

[0257] For example, see Figure 14 The fifth interval 165 includes a plurality of fifth openings 175 and a fifth gap 185. The plurality of fifth openings 175 are arranged at intervals along the second direction B. Two adjacent fifth openings 175 along the second direction B are connected through the fifth gap 185. The third sub-electrode portion 1312c of the second electrode portion 1312 is located in the fifth openings 175 and the fifth gap 185.

[0258] For example, by isolating the first virtual electrode 110 and the first electrode layer 131 by the second isolation structure 192, it is easy to make the shape of the orthographic projection of the second isolation structure 192 on the substrate 104 match (e.g., the same) the shape of the orthographic projection of the first virtual electrode 110 on the substrate 104, so that the shape of the first virtual electrode 110 can be controlled by controlling the shape of the second isolation structure 192.

[0259] For example, see Figure 13 and Figure 14The fifth opening 175 is provided corresponding to the second opening 172. The orthographic projection of the fifth opening 175 on the substrate 104 overlaps with the orthographic projection of the corresponding second opening 172 on the substrate 104 (e.g., completely coincides). The fifth gap 185 is provided corresponding to the second gap 182. The orthographic projection of the fifth gap 185 on the substrate 104 overlaps with the orthographic projection of the corresponding second gap 182 on the substrate 104 (e.g., completely coincides).

[0260] In some embodiments, the first isolation structure 191 and the second isolation structure 192 are disposed in the same layer and made of the same material, thereby simplifying the manufacturing process of the first isolation structure 191 and the second isolation structure 192 and reducing the manufacturing cost of the display panel 100.

[0261] In some embodiments, see Figure 17 At least one isolation structure includes a third isolation structure 193, which is located between the substrate 104 and the second virtual electrode 120. The third isolation structure 193 can isolate the second virtual electrode 120 from the first electrode layer 131.

[0262] For example, see Figure 17 The third isolation structure 193 encloses and forms a connected sixth interval 166 and a fourth auxiliary gap 1874. The fifth sub-electrode 1313e of the third electrode portion 1313 is located in the sixth interval 166, and the sixth sub-electrode 1313f of the third electrode portion 1313 is located in the fourth auxiliary gap 1874. When there are multiple sixth intervals 166, the fifth sub-electrode 1313e in two adjacent sixth intervals 166 are connected through the sixth sub-electrode 1313f located in the fourth auxiliary gap 1874.

[0263] For example, see Figure 16 and Figure 17 The fourth interval 164 and the sixth interval 166 are correspondingly arranged, and the orthographic projection of the fourth interval 164 on the substrate 104 overlaps with the orthographic projection of the corresponding sixth interval 166 on the substrate 104. The second auxiliary gap 1872 and the fourth auxiliary gap 1874 are correspondingly arranged, and the orthographic projection of the second auxiliary gap 1872 on the substrate 104 overlaps with the orthographic projection of the corresponding fourth auxiliary gap 1874 on the substrate 104. For example, the orthographic projection of the fourth interval 164 on the substrate 104 completely coincides with the orthographic projection of the corresponding sixth interval 166 on the substrate 104, and the orthographic projection of the second auxiliary gap 1872 on the substrate 104 completely coincides with the orthographic projection of the corresponding fourth auxiliary gap 1874 on the substrate 104. By controlling the shape of the third isolation structure 193, the shapes of the sixth interval 166 and the fourth auxiliary gap 1874 are controlled, thereby controlling the shapes of the fourth interval 164 and the second auxiliary gap 1872, and controlling the shape of the third electrode portion 1313.

[0264] For example, see Figure 17 The sixth interval 166 includes a plurality of sixth openings 176 and a sixth gap 186. The plurality of sixth openings 176 are arranged at intervals along the first direction A. Two adjacent sixth openings 176 along the first direction A are connected through the sixth gap 186. The fifth sub-electrode 1313e of the third electrode part 1313 is located in the sixth openings 176 and the sixth gap 186.

[0265] For example, by isolating the second virtual electrode 120 and the first electrode layer 131 by the third isolation structure 193, it is easy to make the shape of the orthographic projection of the third isolation structure 193 on the substrate 104 match (e.g., the same) the shape of the orthographic projection of the second virtual electrode 120 on the substrate 104, so that the shape of the second virtual electrode 120 can be controlled by controlling the shape of the third isolation structure 193.

[0266] For example, see Figure 16 and Figure 17 The sixth opening 176 is provided corresponding to the third opening 173. The orthographic projection of the sixth opening 176 on the substrate 104 overlaps with the orthographic projection of the corresponding third opening 173 on the substrate 104 (e.g., completely coincides). The sixth gap 186 is provided corresponding to the third gap 183. The orthographic projection of the sixth gap 186 on the substrate 104 overlaps with the orthographic projection of the corresponding third gap 183 on the substrate 104 (e.g., completely coincides).

[0267] In some embodiments, the first isolation structure 191 and the third isolation structure 193 are disposed in the same layer and made of the same material, which can simplify the manufacturing process of the first isolation structure 191 and the third isolation structure 193 and reduce the manufacturing cost of the display panel 100.

[0268] In some embodiments, see Figure 1 The display panel 100 may further include a pixel defining layer 210, which may be disposed between the isolation structure (taking the first isolation structure 191 as an example) and the substrate 104. The pixel defining layer 210 defines a plurality of pixel openings 211, and the light-emitting unit 1331 is disposed corresponding to the pixel opening 211. At least part of the light-emitting unit 1331 may be located within the corresponding pixel opening 211.

[0269] In some embodiments, see Figure 1 The display panel 100 includes a first encapsulation layer 101, which is located on the side of the touch electrode 140 and the light-emitting unit 1331 away from the substrate 104.

[0270] In some embodiments, see Figure 1The display panel 100 may include a second encapsulation layer 102, which is located on the side of the first encapsulation layer 101 that is away from the substrate 104.

[0271] In some embodiments, the display panel 100 may include a third encapsulation layer 103 located on the side of the second encapsulation layer 102 away from the substrate 104.

[0272] For example, at least one of the first encapsulation layer 101 and the third encapsulation layer 103 may be made of inorganic materials. Inorganic materials have a better barrier effect against water vapor and oxygen, thus achieving a better encapsulation effect.

[0273] For example, the material of the second encapsulation layer 102 may include organic materials, which can help alleviate stress in the film layer.
