[0074] In a display panel 10 provided in an embodiment of the present application, the display panel 10 includes a substrate 100 , an isolation structure 300 , a light emitting device 400 and an auxiliary structure E. The isolation structure 300 is disposed on one side of the substrate 100 , and the isolation structure 300 is provided with an isolation opening 300 a , and the isolation structure 300 can be used to participate in dividing sub-pixels of the display panel 10 .

[0075] Related solutions of the isolation structure 300 (also called partition structure, etc.) are disclosed in patents (applications) CN118251982A, 202410864269.8, PCT / CN2024 / 098407, PCT / CN2024 / 102783, PCT / CN2024 / 098217, PCT / CN2024 / 099419, PCT / CN2024 / 099072, CN117979 755A, CN117998900A, CN117062489A, CN117580403A, CN116583155A, CN116669477A, ​​CN117396039A, CN116669480A, CN116600606A, CN117500332A, etc., the contents of which are incorporated into this application by reference for reference.

[0076] The light emitting device 400 is disposed on one side of the substrate 100 , and the light emitting device 400 can be used to participate in realizing the light emitting display function of the display panel 10 .

[0077] Optionally, there may be multiple light emitting devices 400 .

[0078] The light emitting device 400 includes a first electrode 410 at least partially located in the isolation opening 300 a . Optionally, the first electrode 410 can be used to transmit a negative power supply voltage signal.

[0079] The auxiliary structure E can be electrically connected to the first electrode 410 through the isolation structure 300. For example, the material of the isolation structure 300 may include a conductive material, the auxiliary structure E can be directly contacted and connected to the isolation structure 300, and the isolation structure 300 can be directly contacted and connected to the first electrode 410, so that the auxiliary structure E can be electrically connected to the first electrode 410 through the isolation structure 300.

[0080] Optionally, the first electrodes 410 of adjacent light-emitting devices 400 may also be electrically connected via the isolation structure 300 , so as to facilitate signal transmission to the first electrodes 410 .

[0081] By setting the material of the auxiliary structure E to include semiconductor material, since the semiconductor material may have a certain thermoelectric effect, the auxiliary structure E can use the heat generated when the display panel 10 is working to generate current, so that the auxiliary structure E can provide current to the first electrode 410, which can better reduce the power consumption of the display panel 10 and improve the working stability of the display panel 10.

[0082] Exemplarily, by setting the material of the auxiliary structure E to include a semiconductor material, the auxiliary structure E can generate current in accordance with the thermoelectric effect (e.g., the Seebeck effect), that is, the auxiliary structure E can generate current under the influence of the ambient temperature. Therefore, during the display operation of the display panel 10, the temperature of the display panel 10 is prone to rise, for example, the local temperature of the display panel 10 is prone to rise, so that the auxiliary structure E can generate current by using the temperature difference in the display panel 10. Therefore, the auxiliary structure E can use the heat to provide a certain current to the first electrode 410 during the operation of the display panel 10, which is conducive to increasing the voltage of the first electrode 410 and reducing the power consumption of the display panel 10.

[0083] In some embodiments of the present application, there are multiple ways to set the material of the auxiliary structure E. The material of the auxiliary structure E may include any thermoelectric material. For example, the auxiliary structure E may include semiconductor materials, electrical conductor thermoelectric materials, etc.

[0084] In some optional embodiments, the material of the auxiliary structure E may include semiconductor thermoelectric material, so that the auxiliary structure E can have a larger thermoelectric effect, so that the auxiliary structure E can generate current under the influence of temperature during the operation of the display panel 10, that is, the auxiliary structure E can have a greater ability to convert thermal energy into electrical energy.

[0085] Optionally, the material of the auxiliary structure E includes at least one of an N-type semiconductor material and a P-type semiconductor material.

[0086] For the convenience of description, the following embodiments are described by taking the case where the material of the auxiliary structure E includes an N-type semiconductor material as an example.

[0087] In some embodiments of the present application, the first electrode 410 can be used as a pixel electrode of the display panel 10 to participate in driving the light emitting device 400 in the display panel 10 to emit light. For example, the first electrode 410 can be used to transmit a negative power supply voltage signal (ELVSS signal) and as a cathode to participate in driving the light emitting device 400 in the display panel 10 to emit light.

[0088] Optionally, the display panel 10 provided in the embodiment of the present application may be an organic light emitting diode display panel 10 .

[0089] In some optional embodiments, the light emitting device 400 further includes a second electrode 430 disposed on a side of the first electrode 410 facing the substrate 100 and a light emitting unit 420 disposed between the first electrode 410 and the second electrode 430 .

[0090] Optionally, the light-emitting unit 420 may include a hole injection layer (HIL), a hole transport layer (HTL), a light-emitting structure, an electron injection layer (EIL) and an electron transport layer (ETL).

[0091] Optionally, the second electrode 430 may also be used as a pixel electrode of the display panel 10, one of the first electrode 410 and the second electrode 430 may be used as an anode, and the other may be used as a cathode to drive the light-emitting unit 420 to emit light. In the embodiment of the present application, the first electrode 410 is used as the cathode of the display panel 10, and the second electrode 430 is used as the anode of the display panel 10 for illustration.

[0092] In some optional embodiments, the display panel 10 may further include a pixel definition layer 200 disposed on a side of the second electrode 430 facing away from the substrate 100 . The pixel definition layer 200 may also be used to participate in dividing the sub-pixels of the display panel 10 .

[0093] The pixel definition layer 200 may include a pixel defining portion 210 . The pixel defining portion 210 is provided with a pixel opening 210 a . At least a portion of the surface of the second electrode 430 facing away from the substrate 100 may be exposed from the pixel opening 210 a .

[0094] Exemplarily, at least part of the structure of the light-emitting unit 420 is located in the pixel opening 210a, and at least part of the surface of the second electrode 430 facing away from the substrate 100 is exposed from the pixel opening 210a and connected to the light-emitting unit 420, so that the second electrode 430 drives the light-emitting unit 420 to emit light for display.

[0095] In some embodiments of the present application, there are many ways to set the substrate 100. For example, the substrate 100 may include a substrate 110 and a driving circuit 150 disposed on the side of the substrate 110 facing the light-emitting device 400. Exemplarily, the driving circuit 150 may include a transistor 151, a storage capacitor 152, and a driving signal line for connecting various devices. Among them, the transistor 151 may include a semiconductor, a gate 151a, and a source and drain 151b. The storage capacitor 152 may include a first plate 152a and a second plate 152b.

[0096] Optionally, the substrate 100 may further include a first insulating layer 120, a second insulating layer 130, and a third insulating layer 140 disposed on one side of the substrate 110 and sequentially stacked in a direction away from the substrate 110. As an example, the gate 151a and the first electrode 152a may be located on a side of the first insulating layer 120 facing the substrate 110, the second electrode 152b may be located between the first insulating layer 120 and the second insulating layer 130, and the source and drain 151b may be located between the second insulating layer 130 and the third insulating layer 140.

[0097] In some embodiments of the present application, there are multiple ways to position the auxiliary structure E. For example, since the light-emitting device 400 for light-emitting display is prone to generate a large amount of heat during the operation of the display panel 10, the auxiliary structure E can be arranged as close to the light-emitting device 400 as possible, so that the auxiliary structure E uses the heat generated by the light-emitting device 400 to provide current to the first electrode 410.

[0098] In some optional embodiments, the auxiliary structure E may be disposed in the substrate 100 , so that the arrangement of the auxiliary structure E is not likely to affect the arrangement of the light-emitting device 400 .

[0099] Exemplarily, the auxiliary structure E may be disposed on the side of the third insulating layer 140 facing the substrate 110. For example, the auxiliary structure E may be disposed between the third insulating layer 140 and the second insulating layer 130, so that the auxiliary structure E may be closer to the light-emitting device 400, so that the auxiliary structure E uses the heat generated by the light-emitting device 400 to provide current to the first electrode 410.

[0100] In some other optional embodiments, such as Figure 1 As shown, the auxiliary structure E can be disposed on the same side of the substrate 100 as the light emitting device 400 , so that the auxiliary structure E can be well close to the light emitting device 400 , so that the auxiliary structure E can use the heat generated by the light emitting device 400 to provide current to the first electrode 410 .

[0101] Exemplarily, the light emitting device 400 and the auxiliary structure E may both be disposed on a side of the third insulating layer 140 facing away from the substrate 110 .

[0102] For the convenience of description, the following embodiments are described by taking the auxiliary structure E and the light-emitting device 400 being disposed on the same side of the substrate 100 as an example.

[0103] In some optional embodiments, the auxiliary structure E may be spaced apart from the second electrode 430 and both are disposed on the side of the pixel definition layer 200 facing the substrate 100 . Further, the auxiliary structure E and the second electrode 430 are both disposed between the pixel definition layer 200 and the third insulating layer 140 .

[0104] In this optional embodiment, the auxiliary structure E is disposed between the pixel definition layer 200 and the third insulating layer 140, so that the auxiliary structure E can be relatively close to the light-emitting device 400, so that the auxiliary structure E can use the heat generated by the light-emitting device 400 to provide current to the first electrode 410, and it is also convenient for the auxiliary structure E to be electrically connected to the first electrode 410. In addition, it is also possible to reduce the thickness of the display panel 10 and improve the compactness of the structure of the display panel 10 without adding a new film structure to the display panel 10 to prevent the light-emitting device 400. By setting the auxiliary structure E and the second electrode 430 at a distance, it is not easy to short-circuit between the auxiliary structure E and the second electrode 430, and the influence of the current generated in the auxiliary structure E on the current in the first electrode 410 can be reduced.

[0105] In some optional embodiments, a first gap J1 is provided between the light emitting units 420 of adjacent light emitting devices 400 , and the isolation structure 300 may be electrically connected to the auxiliary structure E through the first gap J1 .

[0106] Optionally, the isolation structure 300 is electrically connected to the auxiliary structure E through the first gap J1, which may mean that the conductive material used to achieve the electrical connection between the isolation structure 300 and the auxiliary structure E may extend through the first gap J1. Figure 1 As shown, when the isolation structure 300 is directly connected to the auxiliary structure E to achieve electrical connection between the isolation structure 300 and the auxiliary structure E, a portion of the isolation structure 300 may be connected to the auxiliary structure E via the first electrode 410 .

[0107] Optionally, there is a first gap J1 between the light emitting units 420 of adjacent light emitting devices 400 , which may mean that the light emitting units 420 of adjacent light emitting devices 400 may be spaced apart from each other.

[0108] In these optional embodiments, by providing a first gap J1 between the light-emitting units 420 of adjacent light-emitting devices 400, light crosstalk is less likely to occur between the light-emitting units 420 of adjacent light-emitting devices 400, and the connection between the isolation structure 300 and the auxiliary structure E thereunder can also be facilitated.

[0109] In some optional embodiments, a second gap J2 is provided between the second electrodes 430 of adjacent light-emitting devices 400 , and at least a portion of the auxiliary structure E is located within the second gap J2 .

[0110] Optionally, a second gap J2 is provided between the second electrodes 430 of adjacent light emitting devices 400 , which may mean that the second electrodes 430 of adjacent light emitting devices 400 may be spaced apart from each other.

[0111] In these optional embodiments, by providing a second gap J2 between the second electrodes 430 of adjacent light-emitting devices 400 , signal entanglement is unlikely to occur between the second electrodes 430 of adjacent light-emitting devices 400 , and arrangement of the auxiliary structure E can also be facilitated.

[0112] In some optional embodiments, the first electrodes 410 of adjacent light-emitting devices 400 may be electrically connected to each other to facilitate control of the first electrodes 410 .

[0113] In some optional embodiments, the pixel defining portion 210 is further provided with a communication opening 210 b , and the auxiliary structure E may be electrically connected to the isolation structure 300 through the communication opening 210 b .

[0114] Optionally, the auxiliary structure E is electrically connected to the isolation structure 300 through the communication opening 210b, which may mean that the conductive material used to achieve the electrical connection between the isolation structure 300 and the auxiliary structure E may extend through the communication opening 210b. Figure 1 As shown, when the isolation structure 300 is directly connected to the auxiliary structure E to realize the electrical connection between the first electrode 410 and the auxiliary structure E, part of the isolation structure 300 may be located in the communication opening 210 b and connected to the auxiliary structure E.

[0115] Optionally, the communication opening 210b is located on the side of the first gap J1 away from the substrate 100, so that the conductive material used to electrically connect the isolation structure 300 and the auxiliary structure E can extend through the communication opening 210b to connect with the auxiliary structure E in the first gap J1.

[0116] In some optional embodiments, the pixel opening 210 a may be in communication with the isolation opening 300 a .

[0117] Optionally, a portion of the structure of the light emitting device 400 may be located in the pixel opening 210a, and another portion of the structure of the light emitting device 400 may extend from the pixel opening 210a to the isolation opening 300a. For example, a portion of the first electrode 410 may be located in the pixel opening 210a, and another portion of the first electrode 410 may extend from the pixel opening 210a to the isolation opening 300a.

[0118] Optionally, there are many ways to set the relative position between the pixel defining portion 210 and the isolation structure 300, for example, Figure 2As shown, the isolation structure 300 can be disposed on the side of the pixel defining portion 210 away from the substrate 100, that is, the isolation structure 300 can be directly disposed on the pixel defining portion 210. Or, for example, the pixel defining portion 210 can be provided with a receiving groove (not shown in the figure), and at least part of the isolation structure 300 can be located in the receiving groove, so that the isolation structure 300 is not likely to have an excessive height compared to the substrate 100, thereby being able to better reduce the thickness of the display panel 10. For ease of description, the following embodiments are described by taking the isolation structure 300 disposed on the side of the pixel defining portion 210 away from the substrate 100 as an example.

[0119] In some optional embodiments, the isolation structure 300 includes a first isolation portion 310 and a second isolation portion 320 located on a side of the first isolation portion 310 away from the substrate 100 , and the second isolation portion 320 is disposed protruding from the first isolation portion 310 toward the isolation opening 300 a .

[0120] By arranging the second isolation portion 320 to protrude from the first isolation portion 310 toward the isolation opening 300a, when the light-emitting unit 420 and the first electrode 410 of the display panel 10 are evaporated, the second isolation portion 320 can block at least a portion of the material used to prepare the light-emitting unit 420 and the first electrode 410, so as to separate the light-emitting unit 420 and the first electrode 410 between adjacent sub-pixels, and can facilitate the formation of a plurality of spaced light-emitting units 420 and the first electrode 410, so that when the light-emitting unit 420 and the first electrode 410 of the display panel 10 are evaporated, there is no need to set a mask with high precision, for example, when the light-emitting unit 420 and the first electrode 410 are evaporated, there is no need to set a high-precision metal mask (Fine Metal Mask, FMM), thereby effectively reducing the production cost of the display panel 10.

[0121] Optionally, the material of the first isolation portion 310 may include a conductive material. Optionally, the first electrode 410 is connected to the first isolation portion 310, so that the first electrode 410 can be electrically connected to the auxiliary structure E through the first isolation portion 310, and the first electrodes 410 of adjacent light-emitting devices 400 can be electrically connected through the first isolation portion 310.

[0122] Optionally, the isolation structure 300 further includes a conductive portion 330 located on the side of the first isolation portion 310 facing the substrate 100 . The conductive portion 330 is disposed protruding from the first isolation portion 310 toward the isolation opening 300 a . The first electrode 410 may be connected to the conductive portion 330 .

[0123] By arranging the conductive portion 330 to protrude from the first isolation portion 310 toward the isolation opening 300 a , the overlap between the first electrode 410 and the conductive portion 330 can be facilitated and the overlap area between the first electrode 410 and the conductive portion 330 can be improved to reduce the resistance of the display panel 10 .

[0124] Exemplarily, a portion of the conductive portion 330 is located in the communication opening 210 b and connected to the auxiliary structure E, so that the first electrode 410 can be electrically connected to the auxiliary structure E through the isolation structure 300 .

[0125] Figure 2 It is a structural schematic diagram of an isolation structure 300, a light-emitting device 400 and an auxiliary structure E according to an embodiment of the present application.

[0127] Optionally, at least two light emitting devices 400 are disposed in each display area AA, and the first electrodes 410 of the light emitting devices 400 in the same display area AA may be electrically connected to each other. Figure 2 As shown, the first electrodes 410 of the light-emitting devices 400 located in the same display area AA may be electrically connected via the isolation structure 300 .

[0128] Optionally, the first electrodes 410 of the light emitting devices 400 located in different display areas AA may be electrically connected to each other. Figure 2 As shown, the first electrodes 410 of the light emitting devices 400 located in different display areas AA may be electrically connected via the isolation structure 300 .

[0129] Optionally, when the display panel 10 includes a pixel definition layer 200, a portion of the connecting openings 210b arranged on the side of the auxiliary structure E away from the substrate 100 may be located in the display area AA where a portion of the light-emitting devices 400 connected to the auxiliary structure E are located, and another portion of the connecting openings 210b arranged on the side of the auxiliary structure E away from the substrate 100 may be located in the display area AA where another portion of the light-emitting devices 400 connected to the auxiliary structure E are located, so as to facilitate the electrical connection of the auxiliary structure E with the first electrode 410 in at least two display areas AA.

[0130] In these optional embodiments, by dividing the display panel 10 into a plurality of display areas AA that can perform light-emitting display, and providing an auxiliary structure E electrically connected to the first electrode 410 in at least two display areas AA, during the operation of the display panel 10, when the light-emitting devices 400 in a portion of the display area AA connected to the auxiliary structure E perform light-emitting display and have a higher temperature, while the light-emitting devices 400 in another portion of the display area AA connected to the auxiliary structure E do not perform light-emitting display and have a lower temperature, the auxiliary structure E can be affected by the temperature difference to better generate current, so that the auxiliary structure E can provide a certain current to the first electrode 410 to reduce the power consumption of the display panel 10.

[0131] Exemplarily, when the light-emitting device 400 in the display area AA connected to one end of the auxiliary structure E performs light-emitting display and has a higher temperature, and the light-emitting device 400 in the display area AA connected to the other end of the auxiliary structure E does not perform light-emitting display and has a lower temperature, there is a temperature difference between the two ends of the auxiliary structure E, so that current can be generated in the auxiliary structure E, thereby enabling the auxiliary structure E to provide current to the first electrode 410, thereby reducing the power consumption of the display panel 10.

[0132] Optionally, at least two display areas AA are adjacent in the first direction X, and at least part of the auxiliary structure E extends along the first direction X and is electrically connected to the first electrode 410 in the display areas AA adjacent in the first direction X. The auxiliary structure E extending along the first direction X can better utilize the temperature difference between the display areas AA adjacent in the first direction X in the display panel 10 to generate current, thereby better reducing the power consumption of the display panel 10.

[0133] Optionally, at least two display areas AA are adjacent in the second direction Y, and at least part of the auxiliary structure E extends along the second direction Y and is electrically connected to the first electrode 410 of the display areas AA adjacent in the second direction Y. The auxiliary structure E extending along the second direction Y can better utilize the temperature difference between the display areas AA adjacent in the second direction Y in the display panel 10 to generate current, thereby better reducing the power consumption of the display panel 10.

[0134] Optionally, the display areas AA may be arranged in an array in the first direction X and the second direction Y, so as to arrange more auxiliary structures E to better utilize the temperature difference in the display panel 10 to generate current. For example, there may be multiple rows of display areas AA arranged at intervals in the second direction Y, and the display areas AA in the same row may be arranged at intervals in the first direction X. There may be multiple columns of display areas AA arranged at intervals in the first direction X, and the display areas AA in the same column may be arranged at intervals in the second direction Y.

[0135] like Figure 2As shown, in some optional embodiments, the isolation structure 300 may include an isolation block 301 arranged corresponding to each display area AA, the isolation block 301 has at least two isolation openings 300a, at least part of the structure of the light-emitting device 400 is located in the isolation opening 300a, and the auxiliary structure E is connected to at least two isolation blocks 301.

[0136] Optionally, the isolation block 301 set corresponding to each display area AA may mean that the display area AA and the isolation block 301 may be set in a one-to-one correspondence. For example, only a single isolation block 301 may be set in a single display area AA, and a single isolation block 301 may only be located in a single display area AA.

[0137] Optionally, the light-emitting device 400 and the isolation opening 300a may be arranged in a one-to-one correspondence. For example, the structure of a single light-emitting device 400 only extends into a single isolation opening 300a, that is, the structure of a single light-emitting device 400 will not extend into two or more isolation openings 300a, and only a partial structure of a single light-emitting device 400 may be arranged in a single isolation opening 300a.

[0138] Optionally, the isolation structure 300 further includes a connection segment 302 connected between at least two adjacent isolation blocks 301 , and the adjacent isolation blocks 301 can be electrically connected via the connection segment 302 , so as to facilitate the control of the first electrode 410 in each display area AA.

[0139] Optionally, the orthographic projection of the auxiliary structure E on the substrate 100 at least partially overlaps with the orthographic projection of the connecting segment 302 on the substrate 100 , so that the auxiliary structure E is connected to the isolation blocks 301 on both sides of the connecting segment 302 .

[0140] In these optional embodiments, the first electrodes 410 of the light emitting devices 400 located in the same display area AA can be electrically connected through the isolation block 301, and the first electrodes 410 of the light emitting devices 400 located in different display areas AA can be electrically connected to the connection segment 302 through the isolation block 301. Since the light emitting devices 400 located in the same display area AA tend to have similar temperatures during the operation of the display panel 10, by providing isolation blocks 301 corresponding to each display area AA and providing the auxiliary structure E connected to at least two isolation blocks 301, during the operation of the display panel 10, the auxiliary structure E can better utilize the temperature difference between each display area AA to provide current to the electrode block 411 through the isolation block 301, thereby reducing the power consumption of the display panel 10.

[0141] Optionally, at least two isolation blocks 301 are adjacent in the first direction X, and at least part of the connecting segment 302 extends along the first direction X and is connected to the isolation blocks 301 adjacent in the first direction X. The auxiliary structure E extending along the first direction X can better utilize the temperature difference between the display areas AA adjacent in the first direction X in the display panel 10 to provide current to the first electrode 410 through the isolation block 301, thereby better reducing the power consumption of the display panel 10.

[0142] Optionally, at least two isolation blocks 301 are adjacent in the second direction Y, and at least part of the connecting segment 302 extends along the second direction Y and is connected to the isolation blocks 301 adjacent in the second direction Y. The auxiliary structure E extending along the second direction Y can better utilize the temperature difference between the display areas AA adjacent in the second direction Y in the display panel 10 to provide current to the first electrode 410 through the isolation block 301, thereby better reducing the power consumption of the display panel 10.

[0143] Optionally, when the display areas AA are arranged in an array in the first direction X and the second direction Y, the isolation blocks 301 may also be arranged in an array in the first direction X and the second direction Y, so as to arrange more auxiliary structures E to better utilize the temperature difference in the display panel 10 to generate current. For example, there may be multiple rows of isolation blocks 301 spaced apart in the second direction Y, and the isolation blocks 301 in the same row may be spaced apart in the first direction X. There may be multiple columns of isolation blocks 301 spaced apart in the first direction X, and the isolation blocks 301 in the same column may be spaced apart in the second direction Y.

[0144] In some optional embodiments, the connecting segment 302 and the isolation block 301 together enclose a first opening 300 b .

[0145] For example, Figure 2 As shown, the first opening 300 b may be surrounded by four isolation blocks 301 and connection segments 302 connected to the four electrode blocks 411 .

[0146] In this optional embodiment, the first opening 300 b formed by the connecting segment 302 and the isolation block 301 can facilitate light transmission of the display panel 10 , can effectively reduce light shielding by the isolation structure 300 , and improve the light transmission performance of the display panel 10 .

[0147] Optionally, the first opening 300b may also contain the material of the first electrode 410, that is, when the isolation structure 300 is used to prepare each light-emitting device 400 of the display panel 10, the material of the first electrode 410 located in the first opening 300b may not need to be removed. Alternatively, optionally, the material of the first electrode 410 may not exist in the first opening 300b, that is, when the isolation structure 300 is used to prepare each light-emitting device 400 of the display panel 10, the material of the first electrode 410 located in the first opening 300b may be removed, so as to better improve the light transmission performance of the display panel 10.

[0148] like Figure 2 As shown, in some optional embodiments, the light-emitting device 400 includes multiple pixel groups 401, and the pixel group 401 includes a first type of device 401a, a second type of device 401b and a third type of device 401c with different luminous colors, and at least one pixel group 401 is arranged in a single display area AA.

[0149] In this optional embodiment, during the operation of the display panel 10, the same pixel group 401 tends to have similar temperatures during the light-emitting period, so the display area AA can be divided into units of at least one pixel group 401, so that the auxiliary structure E can better utilize the temperature difference between each display area AA to provide current to the electrode block 411, thereby reducing the power consumption of the display panel 10. In addition, it is also made less likely that the light-emitting devices 400 in a single pixel group 401 have a large spacing due to the arrangement of the auxiliary structure E, thereby being able to better improve the display effect of the display panel 10.

The auxiliary structure E is electrically connected to the first electrode 410. By setting the material of the auxiliary structure E to include a thermoelectric material, the auxiliary structure E can generate current by using the heat generated when the display panel 10 is working, so that the auxiliary structure E can provide current to the first electrode 410, which can better reduce the power consumption of the display panel 10 and improve the working stability of the display panel 10.

[0178] Optionally, at least two electrode blocks 411 are adjacent in the second direction Y, and at least part of the conductive connection structure 412 extends along the second direction Y and is connected to the electrode blocks 411 adjacent in the second direction Y. The auxiliary structure E extending along the second direction Y can better utilize the temperature difference between the display areas AA adjacent in the second direction Y in the display panel 10 to provide current to the electrode blocks 411, thereby better reducing the power consumption of the display panel 10.

[0179] Optionally, when the display areas AA are arranged in an array in the first direction X and the second direction Y, the electrode blocks 411 may also be arranged in an array in the first direction X and the second direction Y, so as to arrange more auxiliary structures E to better utilize the temperature difference in the display panel 10 to generate current. For example, there may be multiple rows of electrode blocks 411 arranged at intervals in the second direction Y, and the electrode blocks 411 in the same row may be arranged at intervals in the first direction X. There may be multiple columns of electrode blocks 411 arranged at intervals in the first direction X, and the electrode blocks 411 in the same column may be arranged at intervals in the second direction Y.

[0180] Optionally, the conductive connection structure 412 and the electrode block 411 may be enclosed together to form the second opening 410 a .

[0181] For example, Figure 3 As shown, the second opening 410 a may be surrounded by four electrode blocks 411 and a conductive connection structure 412 connected between the four electrode blocks 411 .

[0182] In this optional embodiment, the second opening 410 a formed by the conductive connection structure 412 and the electrode block 411 can facilitate light transmission of the display panel 10 , and can effectively reduce light shielding by the first electrode 410 , thereby improving the light transmission performance of the display panel 10 .

[0183] The embodiment of the second aspect of the present application provides a display device, and the display device includes the display panel 10 of any of the above-mentioned embodiments. Since the display device provided by the embodiment of the second aspect of the present application includes the display panel 10 of any of the above-mentioned first aspects, the display device provided by the embodiment of the second aspect of the present application has the beneficial effects of the display panel 10 of any of the above-mentioned first aspects, which will not be repeated here.

[0184] The display device in the embodiments of the present application includes but is not limited to mobile phones, personal digital assistants (PDAs), tablet computers, e-books, televisions, access control systems, smart landline phones, consoles, and other devices with display functions.

[0185] Figure 5 1 is a schematic structural diagram of an isolation structure 300, a light emitting device 400, an auxiliary structure E and a storage circuit C according to an embodiment of the present application. Figure 6 It is a structural schematic diagram of a first electrode 410, a light-emitting device 400, an auxiliary structure E and a storage circuit C according to an embodiment of the present application.

[0186] like Figure 5 and Figure 6As shown, in some optional embodiments, the display device further includes a storage circuit C electrically connected to the auxiliary structure E, and the storage circuit C is used to store at least part of the current generated by the auxiliary structure E.

[0187] Optional, such as Figure 5 As shown, when the display panel 10 includes the isolation structure 300 , the storage circuit C may be connected to the isolation structure 300 to achieve electrical connection between the storage circuit C and the auxiliary structure E.

[0188] Optional, such as Figure 6 As shown, the storage circuit C may be connected to the first electrode 410 to achieve electrical connection between the storage circuit C and the auxiliary structure E.

[0189] In these optional embodiments, the storage circuit C electrically connected to the auxiliary structure E can be used to store at least part of the current generated in the auxiliary structure E, and the current stored in the storage circuit C can be released when needed to further reduce the power consumption of the display panel 10.

[0190] Exemplarily, the current stored in the storage circuit C may be redundant. For example, when the voltage of the first electrode 410 meets the use requirement and the auxiliary structure E still generates a current, part of the redundant current generated by the auxiliary structure E may be transferred to the storage circuit C for storage, so as to be released when needed, thereby effectively reducing the power consumption of the display panel 10.
