[0116] There is an increasing demand for adding a touch panel to an OLED display device to send information to the OLED display device by touching a portion of the panel with a hand or a separate input member. However, current touch display panels have a problem of poor touch performance.

[0117] Based on the above technical problems, the present application provides a display panel and a display device to improve the touch performance of the display panel. The composition, preparation and other contents of the isolation structure mentioned below are further described in patents CN118251982A, 202410864269.8, PCT / CN2024 / 098407, PCT / CN2024 / 102783, PCT / CN2024 / 098217, PCT / CN2024 / 100935, PCT / CN2024 / 102785, PCT / CN2024 / 099419, PCT / CN2024 / 099072, and CN116685174A for reference.

[0118] First, see Figure 1 An embodiment of the present application provides a display panel 10, including a substrate 11, a touch electrode 15 and an auxiliary electrode 14; the touch electrode 15 is located on one side of the substrate 11; the auxiliary electrode 14 is located between the substrate 11 and the touch electrode 15, and the auxiliary electrode 14 and the touch electrode 15 are electrically connected in parallel.

[0119] Specifically, the display panel 10 may be an organic light emitting diode display panel (Organic Light Emitting Diode, referred to as OLED), a quantum dot electroluminescent display panel (Quantum Dot Light Emitting Diodes, referred to as QLED), or the like.

[0120] The substrate 11 may be a rigid substrate or a flexible substrate. When the substrate 11 is a rigid substrate, the material of the substrate 11 may be glass or silicon wafer, etc. When the substrate 11 is a flexible substrate, the material of the substrate 11 may be polyimide. A driving circuit layer may be provided on one side of the substrate 11 close to the touch electrode. The driving circuit layer includes a pixel driving circuit, and the pixel driving circuit includes a thin film transistor.

[0121] See also Figure 1The auxiliary electrode 14 is located between the substrate 11 and the touch electrode 15 . The auxiliary electrode 14 is electrically connected to the touch electrode 15 in parallel, which is equivalent to connecting two capacitors in parallel. This can increase the touch capacitance, thereby reducing the difficulty of touch driving and improving the touch performance of the display panel 10 .

[0122] In summary, the display panel 10 provided in the embodiment of the present application has the auxiliary electrode 14 located between the substrate 11 and the touch electrode 15, and the auxiliary electrode 14 is electrically connected to the touch electrode 15 in parallel, which can increase the touch capacitance, thereby reducing the difficulty of touch driving and improving the touch performance of the display panel 10.

[0123] See also Figures 1 to 7 In some embodiments, the display panel 10 further includes an isolation structure layer and a light-emitting functional portion 13, the isolation structure layer is disposed on one side of the substrate 11, the isolation structure layer is provided with an isolation structure 12, an isolation gap 12b and a plurality of first openings 12a1 formed by the isolation structure 12; the plurality of light-emitting functional portions 13 are correspondingly disposed in the plurality of first openings 12a1; the orthographic projection of the auxiliary electrode 14 on the substrate 11 is located within the orthographic projection of the isolation gap 12b on the substrate 11.

[0124] Therefore, the space occupied by the auxiliary electrodes 14 and the touch electrodes 15 in the thickness direction of the display panel 10 can be reduced, thereby facilitating the reduction of the thickness of the display panel 10 and making the display panel 10 thinner and lighter.

[0125] See also Figure 1 It should be noted that the isolation structure 12 refers to a structure that can separate adjacent light-emitting functional parts 13. Multiple light-emitting functional parts 13 are correspondingly arranged at multiple first openings 12a1. Adjacent light-emitting functional parts 13 can be separated by the isolation structure 12, thereby avoiding crosstalk between adjacent light-emitting functional parts 13 and improving the display effect of the display panel 10. In addition, by providing an isolation structure layer, the isolation structure layer is provided with an isolation structure 12 and multiple first openings 12a1, and the light-emitting functional part 13 can be manufactured by a patterned photolithography process, thereby eliminating FMM, which is beneficial to improving PPI. In addition, since the light-emitting functional part 13 is manufactured by a patterned photolithography process, compared with the display panel 10 that uses FMM to evaporate the light-emitting functional part 13, the shape of the light-emitting functional part 13 can be made richer and the arrangement method can be more optimized, thereby improving the display effect.

[0126] It is understood that the light-emitting functional part 13 includes at least a light-emitting layer (Emission layer, EML), and 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 blocking layer (HBL) and an electron blocking layer (EBL). Alternatively, the light-emitting functional part 13 may also be a laminated light-emitting layer, that is, including at least two light-emitting layers and a charge generation layer (CGL) located between each adjacent light-emitting layer.

[0127] See also Figures 1 to 4 , Figures 6 to 9 In some embodiments, the display panel 10 further includes a first electrode 201 . The first electrode 201 is located on a side of the light emitting functional portion 13 close to the substrate 11 . The first electrode 201 is electrically insulated from the isolation structure 12 .

[0128] See also Figures 1 to 4 , Figures 6 to 9 In some embodiments, the display panel 10 further includes a second electrode 202 . The second electrode 202 is located on a side of the light emitting functional portion 13 facing away from the substrate 11 . The second electrode 202 is electrically connected to the isolation structure 12 .

[0129] Thus, the second electrodes 202 can be electrically connected through the isolation structure 12, thereby reducing the voltage drop between the plurality of second electrodes 202, thereby improving the uniformity of the brightness of the display screen of the display panel 10 and improving the display quality of the display panel 10. In addition, the isolation structure 12 can have the function of transmitting power signals, thereby reducing the wiring of the display area of ​​the display panel 10.

[0130] It should be noted that the first electrode 201, the light-emitting functional part 13 and the second electrode 202 together constitute a sub-pixel. The first electrode 201 may be an anode, and the second electrode 202 may be a cathode. The first electrode 201 and the second electrode 202 are both electrically connected to the pixel driving circuit, so that the light-emitting functional part 13 can emit light normally, ensuring that the display panel 10 displays normally.

[0131] See also Figures 1 to 4 , Figures 6 to 9In some embodiments, the display panel 10 further includes a second insulating layer 205, which is disposed between the isolation structure 12 and the first electrode 201, and the second insulating layer 205 is provided with a second opening 205a, which is disposed corresponding to the first opening 12a1; at least a portion of the light-emitting functional portion 13 is disposed in the second opening 205a; and the second opening 205a exposes the first electrode 201.

[0132] Therefore, by setting the second insulating layer 205, the first electrode 201 and the sub-isolation structure 12a and the adjacent first electrodes 201 can be insulated from each other, and a second opening 205a corresponding to the first opening 12a1 is opened on the second insulating layer 205, and the second opening 205a exposes the first electrode 201. At least a part of the light-emitting functional part 13 is arranged in the second opening 205a, so as to ensure that the light-emitting functional part 13 is in contact with the first electrode 201, thereby ensuring the normal light emission of the light-emitting functional part 13 and ensuring the normal display of the display panel 10.

[0133] See also Figures 1 to 4 , Figures 6 to 9 In some embodiments, the orthographic projection of the isolation structure 12 on the substrate 11 is located at the periphery of the orthographic projection of the second opening 205 a on the substrate 11 .

[0134] Thus, it is possible to avoid the isolation structure 12 limiting the light emission angle of the light emitting functional part 13 .

[0135] See also Figure 1 , Fig.13 and Fig.14 , Fig.18 and Fig.19 In some embodiments, the isolation structure 12 includes a plurality of sub-isolation structures 12a arranged at intervals, each sub-isolation structure 12a defines at least one first opening 12a1; an isolation gap 12b is provided between adjacent sub-isolation structures 12a; that is, the gap between adjacent sub-isolation structures 12a is the isolation gap 12b.

[0136] See also Figures 1 to 4 , Figures 6 to 9 In some embodiments, the sub-isolation structure 12a includes an isolation body 121 and a blocking portion 122, wherein the blocking portion 122 is located on a side of the isolation body 121 facing away from the substrate 11, and the orthographic projection of the isolation body 121 on the substrate 11 is located within the orthographic projection of the blocking portion 122 on the substrate 11.

[0137] In this way, the sub-isolation structure 12a can form an undercut structure with a "large top and small bottom", and the sub-isolation structure 12a corresponding to the first opening 12a1 can have a "roof", so that the adjacent light-emitting functional parts 13 can be separated during the evaporation process, thereby avoiding crosstalk between light-emitting functional parts 13 of different colors, thereby improving the display effect of the display panel 10.

[0138] See also Figures 1 to 4 , Figures 6 to 9 In some embodiments, there is a distance between the light emitting functional portion 13 and the isolating body 121 .

[0139] In this way, it can be ensured that the film layers of the light-emitting functional parts 13 of different colors are insulated from each other, thereby avoiding the problem of current crosstalk between adjacent light-emitting functional parts 13, and ensuring that when the light-emitting functional parts 13 of the corresponding colors are lit, the current will not be transmitted laterally to the adjacent light-emitting functional parts 13, thereby preventing the display panel 10 from having color crosstalk and improving the display effect.

[0140] See also Fig.13 and Fig.14 , Fig.18 and Fig.19 In some embodiments, the orthographic projection of the sub-isolation structure 12a on the substrate 11 is in a grid shape, and each mesh of the grid structure forms a corresponding isolation opening, namely, the first opening 12a1.

[0141] Thus, the uniformity of the orthographic projection area of ​​the sub-isolation structure 12 a on the substrate 11 can be improved, thereby reducing the difficulty of manufacturing the isolation structure 12 .

[0142] In some embodiments, the orthographic projection of the sub-isolation structure 12a on the substrate 11 is a closed ring. In other words, the sub-isolation structure 12a is a ring structure. Exemplarily, the sub-isolation structure 12a can be a rectangular ring, a circular ring, a triangular ring, etc.

[0143] Thus, the isolation effect of the sub-isolation structure 12 a on the evaporated material can be ensured, and the connection of the evaporated materials of adjacent light-emitting functional parts 13 can be avoided, thereby avoiding crosstalk between adjacent light-emitting functional parts 13 , thereby improving the display effect of the display panel 10 .

[0144] In some embodiments, the material of the isolator 121 includes a conductive material.

[0145] In a specific example, the separator 121 includes at least one metal layer.

[0146] In one example, the material of the metal layer includes at least one of a metal and a metal oxide. For example, the metal may be silver, copper, titanium, aluminum, etc. 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, etc.

[0147] In another example, the insulator 121 may include a first metal layer (not shown) and a second metal layer (not shown) stacked in a direction away from the substrate 11, and the orthographic projection outer contour of the first metal layer on the substrate 11 is located outside the orthographic projection outer contour of the second metal layer on the substrate 11. Here, the first metal layer and the second metal layer are stacked in sequence in a direction away from the substrate 11. In one example, the material of the first metal layer may be Mo, and the material of the second metal layer may be Al.

[0148] In some embodiments, the material of the barrier 122 includes a conductive material. In one example, the barrier 122 may be a metal structure, that is, the material of the barrier 122 is metal, for example, the barrier 122 may be a conductive metal material such as silver, copper, titanium, aluminum, etc.

[0149] Thus, on the one hand, the strength and hardness of the barrier 122 can be improved, so that the barrier 122 is not easy to collapse during the partition structure molding process, and the projection relationship between the barrier 122 and the isolator 121 on the substrate 11 is ensured, which is conducive to obtaining a partition structure of a desired shape. On the other hand, the barrier 122 and the isolator 121 can form a three-layer metal layer stacked, which can reduce the resistance of the isolation structure 12, thereby reducing the power consumption of the display panel 10.

[0150] In some embodiments, the material of the blocking portion 122 includes an insulating material. For example, the material of the blocking portion 122 may be an inorganic material, such as silicon nitride, silicon oxide, and the like.

[0151] Therefore, when a conductive film layer is provided on the side of the isolation structure 12 facing away from the substrate 11, the isolation structure 12 can utilize its own blocking portion 122 to be electrically insulated from the conductive film layer without the need to separately provide an insulating film layer to achieve electrical insulation, thereby facilitating a reduction in the thickness of the display panel 10.

[0152] See also Figures 1 to 4 In some embodiments, the auxiliary electrode 14 is located in the isolation gap 12 b ; the auxiliary electrode 14 is disposed in the same layer as the isolation structure 12 and is electrically insulated.

[0153] Thus, the auxiliary electrode 14 can be manufactured simultaneously when the isolation structure 12 is manufactured, thereby reducing the use of masks and reducing the manufacturing cost of the display panel 10. In addition, the auxiliary electrode 14 and the isolation structure 12 are arranged in the same layer, which is conducive to reducing the thickness of the display panel 10 and making the display panel 10 thinner and lighter.

[0154] See also Figures 1 to 4 In some embodiments, the auxiliary electrode 14 is spaced apart from the isolation structure 12 .

[0155] Thus, the electrical insulation between the auxiliary electrode 14 and the isolation structure 12 can be ensured, thereby ensuring the normal use of the touch function and the display function of the display panel 10.

[0156] See also Figures 1 to 5 In some embodiments, the first insulating layer 17 is further included. The first insulating layer 17 is located on the side of the auxiliary electrode 14 facing away from the substrate 11, and the touch electrode 15 is located on the side of the first insulating layer 17 facing away from the substrate 11; the touch electrode 15 is electrically connected to the auxiliary electrode 14 through the second via 204, and the second via 204 passes through the first insulating layer 17.

[0157] Therefore, by making the first insulating layer 17 located on the side of the auxiliary electrode 14 away from the substrate 11, the touch electrode 15 is located on the side of the first insulating layer 17 away from the substrate 11; the touch electrode 15 is electrically connected to the auxiliary electrode 14 through the second via 204, and the second via 204 passes through the first insulating layer 17, so that the touch electrode 15 and the auxiliary electrode 14 can be connected in parallel.

[0158] See also Figures 1 to 4 , Figures 6 to 9 In some embodiments, it further includes a first encapsulation layer 181, which is located on the side of the light-emitting functional portion 13 away from the substrate 11; the first encapsulation layer 181 is at least partially located in the first opening 12a1 and extends to the side of the isolation structure 12 away from the substrate 11.

[0159] Thus, the first encapsulation layer 181 can encapsulate the light emitting functional part 13 , thereby reducing the probability of water and oxygen corrosion of the light emitting functional part 13 , thereby improving the display effect of the display panel 10 and facilitating extending the service life of the display panel 10 .

[0160] See also Figures 1 to 4 In some embodiments, the first insulating layer 17 and the first packaging layer 181 are disposed on the same layer and are made of the same material.

[0161] Therefore, the first insulating layer 17 can be manufactured simultaneously when the first encapsulation layer 181 is manufactured, thereby reducing the use of masks, reducing the manufacturing process, reducing the manufacturing cost of the display panel 10, and improving the manufacturing efficiency of the display panel 10.

[0162] See also Figure 2 , Figure 4 , Figure 7In some embodiments, the second encapsulation layer 182 and the third encapsulation layer 183 are further included, wherein the second encapsulation layer 182 covers the first encapsulation layer 181 and the touch electrodes 15 ; and the third encapsulation layer 183 covers the second encapsulation layer 182 .

[0163] Thus, multi-layer encapsulation can be achieved through the first encapsulation layer 181 , the second encapsulation layer 182 and the third encapsulation layer 183 , thereby improving the encapsulation reliability, thereby improving the reliability of the display panel 10 , improving the display effect of the display panel 10 , and extending the service life of the display panel 10 .

[0164] In one example, the material of the first encapsulation layer 181 includes an inorganic material; the material of the second encapsulation layer 182 includes an organic material; and the material of the third encapsulation layer 183 includes an inorganic material.

[0165] Thus, the display panel 10 can be protected by stacking the inorganic layer and the organic layer. Inorganic materials generally have good compactness and can isolate water vapor and oxygen. Organic materials have flexible characteristics. Using organic materials as a layer of the second encapsulation layer 182 can buffer stress from the outside, prevent the display panel 10 from being affected by external stress and affect the display effect. At the same time, it can reduce the risk of encapsulation failure caused by inorganic layer breakage.

[0166] See also Figure 6 to Figure 7 In some embodiments, the auxiliary electrode 14 is disposed in the same layer as the first electrode 201 and is electrically insulated.

[0167] Thus, the auxiliary electrode 14 can be manufactured simultaneously with the first electrode, thereby reducing the use of masks and reducing the manufacturing cost of the display panel 10. In addition, the auxiliary electrode 14 and the first electrode 201 are arranged in the same layer, which is conducive to reducing the thickness of the display panel 10 and making the display panel 10 thinner and lighter.

[0168] See also Figure 6 to Figure 7 In some embodiments, the auxiliary electrode 14 is spaced apart from the first electrode 201 .

[0169] Thus, the electrical insulation between the auxiliary electrode 14 and the first electrode 201 can be ensured, thereby ensuring the normal use of the touch function and the display function of the display panel 10.

[0170] See also Figure 6 to Figure 7 In some embodiments, the touch electrode 15 is located in the isolation gap 12 b.

[0171] Therefore, the space occupied by the touch electrode 15 in the thickness direction of the display panel 10 can be reduced, which is beneficial to reducing the thickness of the display panel 10 and making the display panel 10 thinner and lighter.

[0172] See also Figure 6 to Figure 7 In some embodiments, the touch electrode 15 is located on the side of the second insulating layer 205 away from the substrate 11. In a specific example, the touch electrode 15 is located on the surface of the second insulating layer 205 away from the substrate 11; the touch electrode 15 and the auxiliary electrode 14 are connected through the third via 206, and the third via 206 passes through the second insulating layer 205.

[0173] This can help reduce the thickness of the display panel 10 and make the display panel 10 lighter and thinner.

[0174] See also Fig.10 , Fig.12 , Fig.17 In some embodiments, the touch electrode 15 includes a first touch electrode 151 and a second touch electrode 152 that are spaced apart, one of the first touch electrode 151 and the second touch electrode 152 is a transmitting electrode, and the other is a receiving electrode; the auxiliary electrode 14 includes a first auxiliary electrode portion 141, and the first auxiliary electrode portion 141 is electrically connected to the first touch electrode 151 in parallel; the first auxiliary electrode portion 141 is electrically insulated from the second touch electrode 152.

[0175] Thus, by making the touch electrode 15 include the first touch electrode 151 and the second touch electrode 152 arranged at intervals, one of the first touch electrode 151 and the second touch electrode 152 is a transmitting electrode and the other is a receiving electrode, that is, the first touch electrode 151 and the second touch electrode 152 are arranged in the same layer, and the mutual capacitance between the first touch electrode 151 and the second touch electrode 152 realizes the touch function, so that the thickness of the display panel 10 can be reduced while the touch precision and accuracy of the display panel 10 can be improved. In addition, by making the auxiliary electrode 14 include the first auxiliary electrode part 141, the first auxiliary electrode part 141 is electrically connected to the first touch electrode 151 in parallel; the first auxiliary electrode part 141 is electrically insulated from the second touch electrode 152, thereby, the touch capacitance can be increased, thereby reducing the difficulty of touch driving and improving the touch performance of the display panel 10.

[0176] See also Figures 11 to 13 , Figures 17 to 19 In some embodiments, the auxiliary electrode 14 further includes a second auxiliary electrode portion 142 , and the second auxiliary electrode portion 142 is spaced apart from the first auxiliary electrode portion 141 ; the second auxiliary electrode portion 142 is electrically connected in parallel to the second touch electrode 152 .

[0177] Therefore, not only the first touch electrode 151 and the second touch electrode 152 are mutually capacitive and generate a first coupling capacitor, but also the first auxiliary electrode portion 141 and the second auxiliary electrode portion 142 are mutually capacitive and generate a second coupling capacitor. The superposition of the first coupling capacitor and the second coupling capacitor can effectively increase the touch capacitance, thereby reducing the difficulty of touch driving, and further improving the touch performance of the display panel 10.

[0178] See also Fig.10 In some embodiments, the plurality of first touch electrodes 151 extend along the first direction X and are spaced apart along the second direction Y; the plurality of second touch electrodes 152 extend along the second direction Y and are spaced apart along the first direction X; the first direction X and the second direction Y intersect.

[0179] Thus, the coupling area between the first touch electrode 151 and the second touch electrode 152 can be increased, and the change amount of the capacitance signal when a finger touches can be effectively increased, thereby effectively improving the touch sensitivity.

[0180] See also Figures 10 to 12 , Figure 16 to Figure 17 In some embodiments, the first touch electrode 151 includes a plurality of first sub-electrodes 1511 spaced apart along the first direction X, and the plurality of first sub-electrodes 1511 are electrically connected to each other; the first auxiliary electrode portion 141 includes a plurality of first sub-portions 1411 spaced apart, and the plurality of first sub-electrodes 1511 are electrically connected to the plurality of first sub-portions 1411 in parallel.

[0181] In this way, the coupling area between the first touch electrode 151 and the second touch electrode 152 can be increased, and the touch capacitance can be improved, so that the change amount of the capacitance signal when a finger touches can be effectively increased, thereby effectively improving the touch sensitivity.

[0182] See also Figures 10 to 14 , Figures 17 to 19 In some embodiments, the second touch electrode 152 includes a plurality of second sub-electrodes 1521 connected in sequence along the second direction Y; the second auxiliary electrode portion 142 includes a plurality of second sub-portions 1421 arranged at intervals, and the plurality of second sub-portions 1421 are electrically connected in parallel with the plurality of second sub-electrodes 1521 respectively.

[0183] In this way, the coupling area between the first touch electrode 151 and the second touch electrode 152 and the coupling area between the first auxiliary electrode portion 141 and the second auxiliary electrode portion 142 can be increased, thereby further improving the touch capacitance and the change in the capacitance signal when a finger touches, thereby effectively improving the touch sensitivity.

[0184] See also Figure 8 , Fig. 9 , Fig.12In some embodiments, a bridge portion 16 is further included; the first sub-electrodes 1511 of the same first touch electrode 151 are electrically connected via the bridge portion 16 .

[0185] Therefore, by providing the bridge portion 16 , the electrical connection between the first sub-electrodes 1511 of the same first touch electrode 151 can be facilitated, thereby ensuring the normal use of the touch function.

[0186] See also Figure 12 to Figure 14 , Figures 17 to 19 In some embodiments, the orthographic projection of the second sub-electrode 1521 on the substrate 11 overlaps with the orthographic projection of the second sub-portion 1421 on the substrate 11.

[0187] Therefore, the manufacturing of the second sub-electrode 1521 can be facilitated.

[0188] See also Figures 8 to 9 , Fig.12 , Fig.13 , Fig.15 In some embodiments, the bridge portion 16 and the auxiliary electrode 14 are distributed in the same layer and are spaced apart, and the bridge portion 16 is connected to the first sub-electrode 1511 through the first via hole 203 .

[0189] Therefore, the bridge portion 16 can be manufactured simultaneously when the auxiliary electrode 14 is manufactured, thereby reducing the use of masks and lowering the manufacturing cost of the display panel 10 .

[0190] See also Fig.12 , Fig.14 In some of the embodiments, the orthographic projection of the first sub-portion 1411 on the substrate 11 is located within the orthographic projection of the first sub-electrode 1511 on the substrate 11 .

[0191] Therefore, the first sub-electrode 1511 can be conveniently connected to the bridge portion 16 through the first via hole 203 , so that the first sub-electrodes 1511 in the first touch electrode 151 can be conveniently electrically connected to ensure the normal use of the touch function.

[0192] See also Figures 16 to 19 In some embodiments, the bridging portion 16 is connected to the first sub-portion 1411; the bridging portion 16 is electrically insulated from the second sub-portion 1421; the bridging portion 16 is electrically connected to the first sub-electrode 1511 through the first sub-portion 1411, or the first sub-portion 1411 is electrically connected to the first sub-electrode 1511 through the bridging portion 16.

[0193] Thus, by connecting the bridge portion 16 to the first sub-portion 1411, the bridge portion 16 is electrically connected to the first sub-electrode 1511 through the first sub-portion 1411, so that the electrical connection between the first sub-electrodes 1511 in the first touch electrode 151 can be conveniently realized, and there is no need to provide the first via hole 203, so that the manufacturing cost of the display panel 10 can be reduced and the manufacturing efficiency of the display panel 10 can be improved. In addition, by connecting the bridge portion 16 to the first sub-portion 1411, the first sub-portion 1411 is electrically connected to the first sub-electrode 1511 through the bridge portion 16, so that not only the electrical connection between the first sub-electrodes 1511 in the first touch electrode 151 is convenient; but also the parallel connection between the first sub-portion 1411 and the first sub-electrode 1511 can be conveniently realized.

[0194] See also Figures 17 to 19 In some embodiments, the orthographic projection of the first sub-portion 1411 on the substrate 11 overlaps with the orthographic projection of the first sub-electrode 1511 on the substrate 11.

[0195] Therefore, the manufacturing of the first sub-electrode 1511 can be facilitated.

[0196] See also Fig.11 , Fig.13 , Fig.16 , Fig.18 In some embodiments, the bridge portion 16 is located between adjacent second sub-portions 1421 .

[0197] Thus, the bridge portion 16 and the second sub-portion 1421 can be electrically insulated. In addition, the first sub-electrodes 1511 in the first touch electrode 151 can be conveniently electrically connected through the bridge portion 16 to ensure normal use of the touch function.

[0198] See also Figures 1 to 4 In some embodiments, a first conductive portion 19 is further included; the first conductive portion 19 is disposed on a side of the substrate 11 close to the isolation structure 12 ; and adjacent sub-isolation structures 12 a are electrically connected via the first conductive portion 19 .

[0199] Thus, a plurality of sub-isolation structures 12 a arranged at intervals can be connected into one piece, thereby reducing resistance, which is beneficial to reducing power consumption of the display panel 10 .

[0200] See also Figure 1 to Figure 2 In some embodiments, the first electrode 201 and the first conductive portion 19 are disposed in the same layer and are electrically insulated.

[0201] Therefore, the first conductive portion 19 can be manufactured simultaneously when the first electrode 201 is manufactured, thereby reducing the use of masks, reducing the manufacturing process, improving the manufacturing efficiency of the display panel 10, and reducing the manufacturing cost of the display panel 10.

[0202] See also Figure 3 to Figure 4 In some embodiments, the first conductive portion 19 is located on a side of the first electrode 201 close to the substrate 11 ; and the first conductive portion 19 and the first electrode 201 are electrically insulated.

[0203] Thus, the first conductive portion 19 can be manufactured synchronously with the conductive film layer located on the side of the first electrode 201 close to the substrate 11 , thereby reducing the use of masks, reducing the manufacturing process, improving the manufacturing efficiency of the display panel 10 , and reducing the manufacturing cost of the display panel 10 .

[0204] Second, see Figure 1 , Figures 10 to 12 The embodiment of the present application provides a display panel 10, including a substrate 11, an auxiliary electrode 14 and a touch electrode 15; the auxiliary electrode 14 is arranged on one side of the substrate 11, and the auxiliary electrode 14 includes a first auxiliary electrode portion 141 and a second auxiliary electrode portion 142 arranged at intervals; the touch electrode 15 is arranged on the side of the auxiliary electrode 14 away from the substrate 11, and the touch electrode 15 includes a first touch electrode 151 and a second touch electrode 152; one of the first touch electrode 151 and the second touch electrode 152 is a transmitting electrode, and the other is a receiving electrode; the first touch electrode 151 is electrically connected to the first auxiliary electrode portion 141 in parallel; the second touch electrode 152 is electrically connected to the second auxiliary electrode portion 142 in parallel.

[0205] The display panel 10 provided in the embodiment of the present application is configured such that the auxiliary electrode 14 includes a first auxiliary electrode portion 141 and a second auxiliary electrode portion 142 which are arranged at intervals; the touch electrode 15 is arranged on a side of the auxiliary electrode 14 away from the substrate 11, and the first touch electrode 151 of the touch electrode 15 is electrically connected to the first auxiliary electrode portion 141 in parallel; the second touch electrode 152 of the touch electrode 15 is electrically connected to the second auxiliary electrode portion 142 in parallel, so that not only coupling occurs between the first touch electrode 151 and the second touch electrode 152 to generate a first coupling capacitor, but also coupling occurs between the first auxiliary electrode portion 141 and the second auxiliary electrode portion 142 to generate a second coupling capacitor. The superposition of the first coupling capacitor and the second coupling capacitor can effectively increase the touch capacitance, thereby reducing the difficulty of touch driving, and further improving the touch performance of the display panel 10.

[0206] See also Figures 1 to 7 In some embodiments, the display panel further includes an isolation structure layer, which is disposed on one side of the substrate 11, and the isolation structure layer is provided with an isolation structure 12, an isolation gap 12b and a plurality of first openings 12a1 formed by the isolation structure 12; the orthographic projection of the auxiliary electrode 14 on the substrate 11 is located within the orthographic projection of the isolation gap 12b on the substrate 11; the display panel 10 further includes a plurality of light-emitting functional portions 13, and the plurality of light-emitting functional portions 13 are correspondingly disposed in the plurality of first openings 12a1.

[0207] Thus, by providing the isolation structure layer on one side of the substrate 11, the isolation structure layer is provided with the isolation structure 12, the isolation gap 12b and the plurality of first openings 12a1, the orthographic projection of the auxiliary electrode 14 on the substrate 11 is located within the orthographic projection of the isolation gap 12b on the substrate 11, and the light-emitting functional part 13 is correspondingly provided in the first opening 12a1, so that, on the one hand, the occupation of the space in the thickness direction of the display panel 10 by the auxiliary electrode 14 and the touch electrode 15 can be reduced, which is conducive to the thinning of the thickness of the display panel 10 and the thinning of the display panel 10. On the other hand, the isolation structure 12 refers to a structure that can separate adjacent light-emitting functional parts 13, and the plurality of light-emitting functional parts 13 are correspondingly provided in the plurality of first openings 12a1, and the adjacent light-emitting functional parts 13 can be separated by the isolation structure 12, so that the crosstalk between the adjacent light-emitting functional parts 13 can be avoided, and the display effect of the display panel 10 is improved.

[0208] See also Figures 1 to 4 , Figures 6 to 9 In some embodiments, the display panel 10 further includes a first electrode 201 . The first electrode 201 is located on a side of the light emitting functional portion 13 close to the substrate 11 . The first electrode 201 is electrically insulated from the isolation structure 12 .

[0209] See also Figures 1 to 4 , Figures 6 to 9 In some embodiments, the display panel 10 further includes a second electrode 202 . The second electrode 202 is located on a side of the light emitting functional portion 13 facing away from the substrate 11 . The second electrode 202 is electrically connected to the isolation structure 12 .

[0210] Thus, the second electrodes 202 can be electrically connected through the isolation structure 12, thereby reducing the voltage drop between the plurality of second electrodes 202, thereby improving the uniformity of the brightness of the display screen of the display panel 10 and improving the display quality of the display panel 10. In addition, the isolation structure 12 can have the function of transmitting power signals, thereby reducing the wiring of the display area of ​​the display panel 10.

[0211] It should be noted that the first electrode 201, the light-emitting functional part 13 and the second electrode 202 together constitute a sub-pixel. The first electrode 201 may be an anode, and the second electrode 202 may be a cathode. The first electrode 201 and the second electrode 202 are both electrically connected to the pixel driving circuit, so that the light-emitting functional part 13 can emit light normally, ensuring that the display panel 10 displays normally.

[0212] See also Figures 1 to 4 , Figures 6 to 9In some embodiments, the display panel 10 further includes a second insulating layer 205, which is disposed between the isolation structure 12 and the first electrode 201, and the second insulating layer 205 is provided with a second opening 205a, which is disposed corresponding to the first opening 12a1; at least a portion of the light-emitting functional portion 13 is disposed in the second opening 205a; and the second opening 205a exposes the first electrode 201.

[0213] Therefore, by setting the second insulating layer 205, the first electrode 201 and the sub-isolation structure 12a and the adjacent first electrodes 201 can be insulated from each other, and a second opening 205a corresponding to the first opening 12a1 is opened on the second insulating layer 205, and the second opening 205a exposes the first electrode 201. At least a part of the light-emitting functional part 13 is arranged in the second opening 205a, so as to ensure that the light-emitting functional part 13 is in contact with the first electrode 201, thereby ensuring the normal light emission of the light-emitting functional part 13 and ensuring the normal display of the display panel 10.

[0214] See also Figures 1 to 4 , Figures 6 to 9 In some embodiments, the orthographic projection of the isolation structure 12 on the substrate 11 is located at the periphery of the orthographic projection of the second opening 205 a on the substrate 11 .

[0215] Thus, it is possible to avoid the isolation structure 12 limiting the light emission angle of the light emitting functional part 13 .

[0216] See also Figure 1 , Fig.13 and Fig.14 , Fig.18 and Fig.19 In some embodiments, the isolation structure 12 includes a plurality of sub-isolation structures 12a arranged at intervals, each sub-isolation structure 12a defines at least one first opening 12a1; and an isolation gap 12b is provided between adjacent sub-isolation structures 12a. In other words, the gap between adjacent sub-isolation structures 12a is the isolation gap 12b.

[0217] See also Figures 1 to 4 , Figures 6 to 9 In some embodiments, the sub-isolation structure 12a includes an isolation body 121 and a blocking portion 122, wherein the blocking portion 122 is located on a side of the isolation body 121 facing away from the substrate 11, and the orthographic projection of the isolation body 121 on the substrate 11 is located within the orthographic projection of the blocking portion 122 on the substrate 11.

[0218] In this way, the sub-isolation structure 12a can form an undercut structure with a "large top and small bottom", and the sub-isolation structure 12a corresponding to the first opening 12a1 can have a "roof", so that the adjacent light-emitting functional parts 13 can be separated during the evaporation process, thereby avoiding crosstalk between light-emitting functional parts 13 of different colors, thereby improving the display effect of the display panel 10.

[0219] See also Figures 1 to 4 , Figures 6 to 9 In some embodiments, there is a distance between the light emitting functional portion 13 and the isolating body 121 .

[0220] In this way, it can be ensured that the film layers of the light-emitting functional parts 13 of different colors are insulated from each other, thereby avoiding the problem of current crosstalk between adjacent light-emitting functional parts 13, and ensuring that when the light-emitting functional parts 13 of the corresponding colors are lit, the current will not be transmitted laterally to the adjacent light-emitting functional parts 13, thereby preventing the display panel 10 from having color crosstalk and improving the display effect.

[0221] See also Fig.13 and Fig.14 , Fig.18 and Fig.19 In some embodiments, the orthographic projection of the sub-isolation structure 12a on the substrate 11 is in a grid shape; each mesh of the grid structure forms a corresponding isolation opening, namely, the first opening 12a1.

[0222] Thus, the uniformity of the orthographic projection area of ​​the sub-isolation structure 12 a on the substrate 11 can be improved, thereby reducing the difficulty of manufacturing the isolation structure 12 .

[0223] In some embodiments, the orthographic projection of the sub-isolation structure 12 a on the substrate 11 is a closed ring.

[0224] That is to say, the sub-isolation structure 12a is a ring structure. Exemplarily, the sub-isolation structure 12a can be in the shape of a rectangular ring, a circular ring, a triangular ring, etc.

[0225] Thus, the isolation effect of the sub-isolation structure 12 a on the evaporated material can be ensured, and the connection of the evaporated materials of adjacent light-emitting functional parts 13 can be avoided, thereby avoiding crosstalk between adjacent light-emitting functional parts 13 , thereby improving the display effect of the display panel 10 .

[0226] In some embodiments, the material of the isolator 121 includes a conductive material.

[0227] In some embodiments, the material of the blocking portion 122 includes a conductive material.

[0228] In some embodiments, the material of the blocking portion 122 includes insulating material.

[0229] See also Figures 1 to 4 In some embodiments, the auxiliary electrode 14 is located in the isolation gap 12 , and the auxiliary electrode 14 and the isolation structure 12 are disposed in the same layer and are electrically insulated.

[0230] Therefore, the auxiliary electrode 14 can be manufactured simultaneously when the isolation structure 12 is manufactured, thereby reducing the use of masks and lowering the manufacturing cost of the display panel 10 .

[0231] See also Figures 1 to 4 In some embodiments, the auxiliary electrode 14 is spaced apart from the isolation structure 12 .

[0232] Thus, the electrical insulation between the auxiliary electrode 14 and the isolation structure 12 can be ensured, thereby ensuring the normal use of the touch function and the display function of the display panel 10.

[0233] See also Figure 6 to Figure 7 In some embodiments, the auxiliary electrode 14 is disposed in the same layer as the first electrode 201 and is electrically insulated.

[0234] Thus, the auxiliary electrode 14 can be manufactured simultaneously with the first electrode, thereby reducing the use of masks and reducing the manufacturing cost of the display panel 10. In addition, the auxiliary electrode 14 and the first electrode 201 are arranged in the same layer, which is conducive to reducing the thickness of the display panel 10 and making the display panel 10 thinner and lighter.

[0235] See also Figure 6 to Figure 7 In some embodiments, the auxiliary electrode 14 is spaced apart from the first electrode 201 .

[0236] Thus, the electrical insulation between the auxiliary electrode 14 and the first electrode 201 can be ensured, thereby ensuring the normal use of the touch function and the display function of the display panel 10.

[0237] See also Figure 6 to Figure 7 In some embodiments, the touch electrode 15 is located in the isolation gap 12 b.

[0238] Therefore, the space occupied by the touch electrodes 15 in the thickness direction of the display panel 10 can be reduced, which is beneficial to reducing the thickness of the display panel 10 and making the display panel 10 thinner and lighter.

[0239] See also Figure 6 to Figure 7 In some embodiments, the touch electrode 15 is located on the side of the second insulating layer 205 away from the substrate 11. In a specific example, the touch electrode 15 is located on the surface of the second insulating layer 205 away from the substrate 11; the touch electrode 15 and the auxiliary electrode 14 are connected through the third via 206, and the third via 206 passes through the second insulating layer 205.

[0240] This can help reduce the thickness of the display panel 10 and make the display panel 10 lighter and thinner.

[0241] See also Fig.10 In some embodiments, the plurality of first touch electrodes 151 extend along the first direction X and are spaced apart along the second direction Y; the plurality of second touch electrodes 152 extend along the second direction Y and are spaced apart along the first direction X; the first direction X and the second direction Y intersect.

[0242] Thus, the coupling area between the first touch electrode 151 and the second touch electrode 152 can be increased, and the change amount of the capacitance signal when a finger touches can be effectively increased, thereby effectively improving the touch sensitivity.

[0243] See also Figures 10 to 12 , Figure 16 to Figure 17 In some embodiments, the first touch electrode 151 includes a plurality of first sub-electrodes 1511 spaced apart along the first direction X, and the plurality of first sub-electrodes 1511 are electrically connected to each other; the first auxiliary electrode portion 141 includes a plurality of first sub-portions 1411 spaced apart, and the plurality of first sub-electrodes 1511 are electrically connected to the plurality of first sub-portions 1411 in parallel.

[0244] In this way, the coupling area between the first touch electrode 151 and the second touch electrode 152 can be increased, and the touch capacitance can be improved, so that the change amount of the capacitance signal when a finger touches can be effectively increased, thereby effectively improving the touch sensitivity.

[0245] See also Figures 10 to 14 , Figures 17 to 19 In some embodiments, the second touch electrode 152 includes a plurality of second sub-electrodes 1521 connected in sequence along the second direction Y; the second auxiliary electrode portion 142 includes a plurality of second sub-portions 1421 arranged at intervals, and the plurality of second sub-portions 1421 are electrically connected in parallel with the plurality of second sub-electrodes 1521 respectively.

[0246] In this way, the coupling area between the first touch electrode 151 and the second touch electrode 152 and the coupling area between the first auxiliary electrode portion 141 and the second auxiliary electrode portion 142 can be increased, thereby further improving the touch capacitance and the change in the capacitance signal when a finger touches, thereby effectively improving the touch sensitivity.

[0247] See also Figure 8 , Fig. 9 , Fig.12 In some embodiments, a bridge portion 16 is further included; the first sub-electrodes 1511 of the same first touch electrode 151 are electrically connected via the bridge portion 16 .

[0248] Therefore, by providing the bridge portion 16 , the electrical connection between the first sub-electrodes 1511 of the same first touch electrode 151 can be facilitated, thereby ensuring the normal use of the touch function.

[0249] See also Figure 12 to Figure 14 , Figures 17 to 19 In some embodiments, the orthographic projection of the second sub-electrode 1521 on the substrate 11 overlaps with the orthographic projection of the second sub-portion 1421 on the substrate 11.

[0250] Therefore, the manufacturing of the second sub-electrode 1521 can be facilitated.

[0251] See also Figures 8 to 9 , Fig.12 , Fig.13 , Fig.15 In some embodiments, the bridge portion 16 and the auxiliary electrode 14 are distributed in the same layer and are spaced apart, and the bridge portion 16 is connected to the first sub-electrode 1511 through the first via hole 203 .

[0252] Therefore, the bridge portion 16 can be manufactured simultaneously when the auxiliary electrode 14 is manufactured, thereby reducing the use of masks and lowering the manufacturing cost of the display panel 10 .

[0253] See also Fig.12 , Fig.14 In some of the embodiments, the orthographic projection of the first sub-portion 1411 on the substrate 11 is located within the orthographic projection of the first sub-electrode 1511 on the substrate 11 .

[0254] Therefore, the first sub-electrode 1511 can be conveniently connected to the bridge portion 16 through the first via hole 203 , so that the first sub-electrodes 1511 in the first touch electrode 151 can be conveniently electrically connected to ensure the normal use of the touch function.

[0255] See also Figures 16 to 19 In some embodiments, the bridging portion 16 is connected to the first sub-portion 1411; the bridging portion 16 is electrically insulated from the second sub-portion 1421; the bridging portion 16 is electrically connected to the first sub-electrode 1511 through the first sub-portion 1411, or the first sub-portion 1411 is electrically connected to the first sub-electrode 1511 through the bridging portion 16.

[0256] Thus, by connecting the bridge portion 16 to the first sub-portion 1411, the bridge portion 16 is electrically connected to the first sub-electrode 1511 through the first sub-portion 1411, so that the electrical connection between the first sub-electrodes 1511 in the first touch electrode 151 can be conveniently realized, and there is no need to provide the first via hole 203, so that the manufacturing cost of the display panel 10 can be reduced and the manufacturing efficiency of the display panel 10 can be improved. In addition, by connecting the bridge portion 16 to the first sub-portion 1411, the first sub-portion 1411 is electrically connected to the first sub-electrode 1511 through the bridge portion 16, so that not only the electrical connection between the first sub-electrodes 1511 in the first touch electrode 151 is convenient; but also the parallel connection between the first sub-portion 1411 and the first sub-electrode 1511 can be conveniently realized.

[0257] See also Figures 17 to 19 In some embodiments, the orthographic projection of the first sub-portion 1411 on the substrate 11 overlaps with the orthographic projection of the first sub-electrode 1511 on the substrate 11.

[0258] Therefore, the manufacturing of the first sub-electrode 1511 can be facilitated.

[0259] See also Fig.11 , Fig.13 , Fig.16 , Fig.18 In some embodiments, the bridge portion 16 is located between adjacent second sub-portions 1421 .

[0260] Thus, the bridge portion 16 and the second sub-portion 1421 can be electrically insulated. In addition, the first sub-electrodes 1511 in the first touch electrode 151 can be conveniently electrically connected through the bridge portion 16 to ensure normal use of the touch function.
