[0044] Figure 1 A schematic plan view of a display panel provided in an embodiment of the present application, Figure 2 A method provided in the embodiment of the present application Figure 1 Schematic diagram of the cross section along the A-A' direction.

[0045] The present application embodiment provides a display panel AA, combined with Figure 1 , Figure 2As shown, the display panel AA includes an array substrate 100, and the array substrate 100 includes a substrate 10 and a first electrode 20 and a first touch electrode 301 located on one side of the substrate 10. The display panel AA also includes a light-emitting device 200, and the light-emitting device 200 includes a connecting electrode 40, and the connecting electrode 40 is electrically connected to the first electrode 20. The array substrate 100 can drive the light-emitting device 200 to emit light. When the connecting electrode 40 of the light-emitting device 200 is prepared on the array substrate 100, it is electrically connected to the first electrode 20 through the connecting electrode 40. Optionally, the display panel provided in the embodiment of the present application can be a Micro LED panel, and the light-emitting device 200 can be prepared on the array substrate 100 by transfer technology. The first touch electrode 301 can be used to process a touch signal. Optionally, the first touch electrode 301 can be used as a touch electrode in a self-capacitive touch unit or a mutual-capacitive processing unit.

[0046] In the embodiment of the present application, the first touch electrode 301 is prepared in the same layer as the first electrode 20, which is conducive to avoiding the situation where the first touch electrode 301 occupies a film layer alone, thereby helping to reduce the film thickness and the number of film layer structures of the display panel AA, and reducing the structural complexity of the display panel AA. In addition, it is also conducive to reducing the process of manufacturing the display panel AA and improving the manufacturing efficiency of the display panel AA.

[0047] Figure 3 A schematic plan view of another display panel provided in an embodiment of the present application is shown in FIG. Figure 4 A method provided in the embodiment of the present application Figure 3 Schematic diagram of the cross section along the BB' direction.

[0048] In one embodiment of the present application, Figure 3 , Figure 4 As shown, the display panel AA further includes a second touch electrode 302, and the second touch electrode 302 is further away from the substrate 10 than the surface of the light emitting device 200 away from the substrate 10. As can be seen from the above content, the first touch electrode 301 and the first electrode 20 are in the same layer, so the second touch electrode 302 is located on the side of the first touch electrode 301 away from the substrate 10. The second touch electrode 302 is also used to process touch signals, and the embodiment of the present application is described by taking the mutual capacitive touch unit formed between the first touch electrode 301 and the second touch electrode 302 as an example.

[0049] One of the first touch electrode 301 and the second touch electrode 302 can be used as a touch signal receiving electrode, and the other can be used as a touch signal transmitting electrode. At least one of the first touch electrode 301 and the second touch electrode 302 is located closer to the light emitting surface of the display panel AA, so as to more sensitively receive the user's touch action and make accurate judgments.

[0050] In the embodiment of the present application, the second touch electrode 302 is arranged on the surface of the light emitting device 300 away from the substrate 10, which is conducive to improving the position of the second touch electrode 302 in the display panel AA, so as to facilitate the second touch electrode 302 to receive the touch signal in time, for example, the second touch electrode 302 is closer to the finger of the user when touching the screen. In addition, the second touch electrode 302 is arranged farther away from the substrate 10 than the surface of the light emitting device 200 away from the substrate 10, which is conducive to reducing the influence of the electric field of the light emitting device 200 on the second touch electrode 302, reducing the interference of the electrode signal of the light emitting device 200 on the judgment of the second touch electrode 302, and improving the anti-interference ability of the second touch electrode 302, thereby improving the accuracy of the touch signal processing of the touch unit formed by the second touch electrode 302 and the first touch electrode 301.

[0051] In one embodiment of the present application, the first touch electrode 301 is a touch transmitting electrode, and the second touch electrode 302 is a touch receiving electrode. In the embodiment of the present application, the first touch electrode 301 is located on a side away from the light emitting surface of the display panel AA compared to the second touch electrode 302, and the second touch electrode 302 is set as a touch receiving electrode, which is conducive to more accurate and rapid capture of touch signals. The first touch electrode 301 is set as a touch transmitting electrode, and the first touch electrode 301 is located on one side of the array substrate 100, which is closer to the array substrate, which is conducive to the first touch electrode 301 relying on the wiring in the array substrate 100 to transmit a signal of a specific frequency, so that a changing electric field is established between the touch transmitting electrode and the touch receiving electrode, and then when the second touch electrode 302 senses the touch signal, it can determine the touch position by detecting the current change on the electrode, so as to make a touch response.

[0052] In one embodiment of the present application, continue to refer to Figure 3 , Figure 4As shown, the display panel AA also includes a dielectric layer 303, and the dielectric layer 303 is located between the first touch electrode 301 and the second touch electrode 302 in a direction perpendicular to the plane where the display panel AA is located. The dielectric layer 303 includes a dielectric material that can be used as a dielectric material between the first touch electrode 301 and the second touch electrode 302, which is conducive to forming a mutual capacitance between the first touch electrode 301 and the second touch electrode 302. Optionally, an insulating layer is included between the dielectric layer 303 and the first electrode 20, which is conducive to avoiding the first electrode 20 and the first touch electrode 302 from simultaneously serving as the plate of the dielectric layer 303. When a user approaches or contacts the touch display panel with a finger or other conductive object, additional capacitance is introduced at this position, thereby changing the local mutual capacitance value. The touch control module in the display panel AA calculates the capacitance value of each mutual capacitance point by measuring the current on the second touch electrode 302. The display panel AA touch control module determines which mutual capacitance points are affected by the touch by comparing the capacitance changes of all mutual capacitance points, and obtains the specific position of the touch, thereby making corresponding touch feedback according to the position information.

[0053] In one embodiment of the present application, continue to refer to Figure 3 , Figure 4 As shown, the dielectric layer 303 at least partially surrounds the light emitting device 200. The first touch electrode 301 and the first electrode 20 are arranged in the same layer in the embodiment of the present application, and the second touch electrode 302 is located on the surface of the light emitting device 200 away from the substrate 10. Then, at least part of the dielectric layer 303 located between the first touch electrode 301 and the second touch electrode 302 is adjacent to the light emitting device 200 in a direction parallel to the plane where the display panel AA is located. Since the second touch electrode 302 is located on the surface of the light emitting device 200 away from the substrate 10, in the direction where the dielectric layer 303 is adjacent to the light emitting device 200, it is conducive to providing conditions for the portion between two adjacent light emitting devices 200 to be completely shielded by the dielectric layer 303.

[0054] In an embodiment of the present application, the dielectric layer 303 is set as a shading layer. Optionally, the dielectric layer 303 includes a non-light-transmitting material, which is conducive to utilizing the dielectric layer 303 to multiplex as a shading structure for two adjacent light-emitting devices 200, thereby reducing the light crosstalk between adjacent light-emitting devices 200 to a certain extent and improving the display effect of the display panel AA.

[0055] Figure 5 A schematic plan view of another display panel provided in an embodiment of the present application is shown in FIG. Figure 6 A method provided in the embodiment of the present application Figure 5 Schematic diagram of the cross section along the C-C' direction.

[0056] In one embodiment of the present application, Figure 5 , Figure 6As shown, in a direction perpendicular to the plane where the display panel AA is located, at least a portion of the dielectric layer 303 covers the light emitting device 200 . Optionally, the dielectric layer 303 may entirely cover the array substrate 100 and the light emitting device 200 .

[0057] In the embodiment of the present application, the prepared dielectric layer 303 is provided to at least partially cover the light emitting device 200, which is conducive to ensuring that when preparing the second touch electrode 302, the second touch electrode 302 can be located at a position farther away from the substrate 10 than the surface of the light emitting device 200 away from the substrate 10. It is conducive to avoiding the situation that after the dielectric layer 303 is prepared, the dielectric layer 303 is slightly sunken compared to the film layer where the light emitting device 200 is located due to process reasons, thereby causing the position of the second touch electrode 302 prepared later to be in the same layer as the light emitting device 200 or to be almost aligned with the surface of the light emitting device 200 away from the substrate 10. In summary, the provision of at least partially covering the dielectric layer 303 is conducive to ensuring that the second touch electrode 302 is in a preset position, thereby ensuring the accuracy and sensitivity of the second touch electrode 302 sensing the touch signal.

[0058] In one embodiment of the present application, the dielectric layer 303 is a light-transmitting film layer. Optionally, the dielectric layer 303 includes a light-transmitting material. In the embodiment of the present application, the dielectric layer 303 is set as a light-transmitting film layer, which is conducive to reducing the influence of the dielectric layer 303 on the light emission of the light-emitting device 200 when covering the light-emitting device 200, ensuring the normal light emission of the light-emitting device 200, and avoiding the use of the dielectric layer 303 to reduce the light emission rate of the display panel AA.

[0059] Figure 7 Another embodiment provided in this application is Figure 5 Schematic diagram of the cross section along the C-C' direction, Figure 8 Another embodiment provided in this application is Figure 5 Schematic diagram of the cross section along the C-C' direction.

[0060] In one embodiment of the present application, Figure 5 , Figure 7 As shown, the dielectric layer 303 includes a first sub-dielectric layer 303A and a second sub-dielectric layer 303B. The second sub-dielectric layer 303B is located on the side of the first sub-dielectric layer 303A away from the substrate 10 , which is conducive to providing conditions for at least part of the second sub-dielectric layer 303B to cover the light-emitting device 200 .

[0061] In the embodiment of the present application, the first sub-dielectric layer 303A is set as a light shielding layer, and the first sub-dielectric layer 303A at least partially surrounds the light emitting device 200, which is conducive to reusing the first sub-dielectric layer 303A as a light shielding structure between adjacent light emitting devices 200, reducing the light crosstalk problem, thereby improving the display effect of the display panel AA. In addition, the second sub-dielectric layer 303B is set as a light-transmitting film layer, and at least part of the second sub-dielectric layer 303B covers the light emitting device 200 in a direction perpendicular to the plane of the display panel AA, which is conducive to using the second sub-dielectric layer 303B to ensure that the second touch electrode 302 can be prepared at a preset position. The dielectric layer 303 is arranged to include a first sub-dielectric layer 303A and a second sub-dielectric layer 303B, and is provided with different functions in addition to being a dielectric material, and a shielding structure and a covering structure are respectively provided. This helps to avoid the situation where the dielectric layer 303 is entirely made of shading material and covers the portion of the surface of the light-emitting device 200 away from the substrate, thereby affecting the light-emitting area of ​​the light-emitting device 200. It also helps to avoid the situation where the dielectric layer 303 between adjacent light-emitting devices 200 cannot prevent light crosstalk when the dielectric layer 303 is entirely made of transparent material. This helps to improve the availability of the dielectric layer 303 and improve the display effect and touch effect of the display panel AA.

[0062] Alternatively, if Figure 8 As shown, the height of the first sub-dielectric layer 303A is slightly lower than the plane where the light-emitting device 200 is located in the direction perpendicular to the plane where the display panel AA is located, which is beneficial to prevent the side of the light-emitting device 200 from being completely blocked by the non-light-transmitting material on the basis of using the first sub-dielectric layer 303A as a light-shielding structure, so that the light-emitting device 200 has a good light-emitting effect at a wide viewing angle. In addition, the first sub-dielectric layer 303A is slightly lower than the plane where the light-emitting device 200 is located during preparation, which is beneficial to avoid the situation where part of the material of the first sub-dielectric layer 303A is blocked on the surface of the light-emitting device 200 due to process preparation and other reasons, thereby ensuring that the light-emitting effect of the front of the light-emitting device 200 is good and the light-emitting area of ​​the light-emitting device 200 is ensured. At the same time, the second sub-dielectric layer 303B is set higher than the plane where the light-emitting device 200 is located, which is beneficial to ensure that the prepared second touch electrode 302 is higher than the plane where the light-emitting device 200 is located, thereby ensuring that the touch sensitivity of the display panel AA is good.

[0063] Fig. 9 A schematic plan view of another display panel provided in an embodiment of the present application is shown in FIG. Fig.10 A method provided in the embodiment of the present application Fig. 9 Schematic diagram of the cross section along the D-D' direction.

[0064] In one embodiment of the present application, Fig. 9 , Fig.10As shown, the first electrode 20 includes a first type of first electrode 20A and a second type of first electrode 20B, the connecting electrode 40 includes a first type of connecting electrode 40A and a second type of connecting electrode 40B, the first type of first electrode 20A is electrically connected to the first type of connecting electrode 40A, and the second type of first electrode 20B is electrically connected to the second type of connecting electrode 40B. The light emitting device 200 includes an anode and a cathode, and the array substrate 100 transmits an electrical signal from the first electrode 20 to the connecting electrode 40 of the light emitting device 200, thereby driving the light emitting device 200 to emit light. Optionally, the first type of connecting electrode 40A is the cathode of the light emitting device 200, and the second type of connecting electrode 40B is the anode of the light emitting device 200. This application takes the example that the array substrate 200 transmits different electrical signals to the second type of connecting electrode 40B of the light emitting device 200 through the second type of first electrode 20B, so that the light emitting device 200 can generate different light brightness, and the first type of first electrode 20A transmits a fixed electrical signal to the first type of connecting electrode 40A of the light emitting device 200.

[0065] In the embodiment of the present application, the first-type connecting electrodes 40A of at least two light-emitting devices 200 are electrically connected, which is beneficial for connecting the first-type first connecting electrodes 20A of multiple light-emitting devices 200 with a fixed electrical signal to the same signal terminal, and is beneficial for making the potentials of the first-type connecting electrodes 40A of the multiple light-emitting devices 200 at the same or similar level, reducing the potential difference of the first-type connecting electrodes 40A of the multiple light-emitting devices 200, and improving the accuracy of the light-emitting brightness of the multiple light-emitting devices 200.

[0066] The embodiment of the present application further arranges the first-type first electrode 20A between the first touch electrode 301 and the second-type connecting electrode 40B. In the direction in which the second-type first electrode 20B is adjacent to the first touch electrode 301, the first touch electrode 301 is also adjacent to the first-type first electrode 20A. It can be seen from the above content that the first-type first electrode 20A can transmit a fixed electrical signal. Then, the first touch electrode 301 is adjacent to the first-type first electrode 20A, which is beneficial to avoiding the risk of the first touch electrode 301 being subjected to relatively strong electromagnetic interference, thereby improving the accuracy of the signal transmitted by the first touch electrode 301, and further improving the accuracy of the mutual capacitance test between the first touch electrode 301 and the second touch electrode 302, thereby ensuring the stability of the touch function.

[0067] In one embodiment of the present application, continue to refer to Fig. 9 , Fig.10As described, the first type of first electrode 20A at least partially surrounds the first touch electrode 301. It can be seen from the above embodiment that the first touch electrode 301 is adjacent to the first type of first electrode 20A, which is conducive to improving the accuracy of the signal transmitted by the first touch electrode 301. The first type of first electrode 20A is set to at least partially surround the first touch electrode 301, so that the periphery of the first touch electrode 301 is equivalent to setting a layer of anti-interference barrier, further improving the reliability of the signal transmitted by the first touch electrode 301, thereby improving the stability of the touch function of the display panel AA. It should be noted that, optionally, the first touch electrode 301 is not connected to the first type of first electrode 20A, which is conducive to the first touch electrode 301 and the first type of first electrode 20A each transmitting the required electrical signal, avoiding signal crosstalk, and affecting the accuracy of the luminous brightness and the stability of the touch function.

[0069] In one embodiment of the present application, the array substrate 100 further includes a plurality of pixel circuits 50 and a plurality of cascaded shift register circuits 60. The shift register circuit 60 is electrically connected to the pixel circuit 50 via a selection signal line, and the output end of the shift register circuit 60 is electrically connected to the selection signal line, and the selection signal line provides a selection signal to the pixel circuit 50 for driving the pixel circuit 50 to work. Optionally, the selection signal includes a light-emitting drive signal and a scanning signal. Fig. 9 As shown, optionally, the shift register 60 is arranged in the display area, and in the cascade direction of multiple shift registers 60, a pixel circuit 50 is arranged between at least some adjacent shift register circuits 60, and a shift register circuit 60 is arranged between at least some adjacent pixel circuits 50, and the shift register 60 and the pixel circuit 50 can be arranged alternately.

[0070] The pixel circuit 50 can transmit the light-emitting driving current to the light-emitting device 200, and the pixel circuit 50 is electrically connected to the light-emitting device 200. Optionally, in a direction perpendicular to the plane where the display panel AA is located, at least part of the light-emitting device 200 overlaps with at least part of the pixel circuit 50. Since in the embodiment of the present application, the light-emitting device 200 and the first touch electrode 301 are arranged to be adjacent in a direction parallel to the plane where the display panel AA is located, there is a situation in which the first touch electrode 301 overlaps with at least part of the pixel circuit 50 and / or the first touch electrode 301 overlaps with at least part of the shift register circuit 60 in a direction perpendicular to the plane where the display panel AA is located.

[0071] Alternatively, if Fig.11 As shown, along a direction H perpendicular to the plane where the display panel AA is located, the first touch electrode 301 overlaps with at least a portion of the pixel circuit 50 .

[0072] Alternatively, if Fig.12 As shown, along a direction H perpendicular to the plane where the display panel AA is located, the first touch electrode 301 overlaps with at least a portion of the shift register circuit 60 .

[0073] Alternatively, if Fig.13 As shown, along a direction H perpendicular to the plane where the display panel AA is located, the first touch electrode 301 overlaps with at least a portion of the pixel circuit 50 and at least a portion of the shift register circuit 60 .

[0074] It should be noted that both the pixel circuit 50 and the shift register circuit 60 include a plurality of thin film transistors. Figure 10-12 The pixel circuit 50 including a thin film transistor and the shift register circuit 60 including a thin film transistor are only for illustration. Optionally, the pixel circuit 50 is electrically connected to the anode of the light emitting device 200 through a punch hole.

[0075] In one embodiment of the present application, continue to refer to Figure 11-13 As shown, the array substrate 100 also includes a shielding layer 70. Along a direction perpendicular to the plane where the display panel AA is located, the shielding layer 70 is located between the first touch electrode 301 and the pixel circuit 50, which is beneficial to isolating the electric field between the first touch electrode 301 and the pixel circuit 50 to a certain extent, reducing the signal crosstalk between the first touch electrode 301 and the pixel circuit 50, and improving the accuracy of signal transmission by the first touch electrode 301 and the accuracy of signal transmission by the pixel circuit 50.

[0076] Alternatively, setting the shielding layer 70 between the first touch electrode 301 and the shift register circuit 60 is beneficial to isolating the electric field between the first touch electrode 301 and the shift register circuit 60 to a certain extent, reducing the signal crosstalk between the first touch electrode 301 and the shift register circuit 60, and improving the accuracy of signal transmission by the first touch electrode 301 and the accuracy of signal transmission by the shift register circuit 60.

[0077] Optionally, refer to Fig.12 As shown, the shielding layer 70 can be laid as a whole layer to effectively shield the electric field between the array substrate 100 and the first touch electrodes 301 , thereby improving the working stability of the display panel AA.

Fig.15 A schematic plan view of another display panel provided in an embodiment of the present application is shown in FIG. Fig.16 A schematic plan view of another display panel provided in an embodiment of the present application.

[0079] In one embodiment of the present application, Fig.14 As shown, along the plane perpendicular to the display panel AA, the shielding layer 70 covers at least two pixel circuits 50 adjacent to each other along the first direction X1, and at least two pixel circuits 50 adjacent to each other along the second direction X2, so that the shielding layer 70 covers as many pixel circuits 50 as possible, increasing the coverage area of ​​the shielding layer 70, which is conducive to improving the ability and scope of the shielding layer 70 to prevent crosstalk between the first touch electrode 301 and the pixel circuit 50. The first direction X1 and the second direction X2 intersect and are parallel to the plane where the display panel AA is located.

[0080] Or, if Fig.15 As shown, along a plane perpendicular to the display panel AA, the shielding layer 70 covers at least two shift register circuits 60 adjacent to each other along the first direction X1, and at least two shift register circuits 60 adjacent to each other along the second direction X2, so that the shielding layer 70 covers as many shift register circuits 60 as possible, thereby increasing the coverage area of ​​the shielding layer 70, which is beneficial to improving the ability and range of action of the shielding layer 70 to prevent crosstalk between the first touch electrode 301 and the shift register circuit 60.

[0081] Alternatively, if Fig.16 As shown, the shielding layer 70 is laid out over the entire surface in a direction perpendicular to the plane of the display panel AA, covering multiple pixel circuits 50 and multiple shift register circuits 60, which is beneficial to further improve the ability and scope of the shielding layer 70 to prevent crosstalk between the first touch electrode 301 and the pixel circuit 50 and the shift register circuit 60.

[0082] In one embodiment of the present application, the shielding layer 70 is electrically connected to a fixed electrical signal, which helps to prevent the shielding layer 70 from generating a changing electric field, thereby helping to improve the reliability of the shielding layer 70 in preventing signal crosstalk.

[0083] Fig.17 Another embodiment provided in this application is Figure 1 Schematic diagram of the cross section along the A-A' direction.

[0084] In one embodiment of the present application, Figure 1 , Fig.17 As shown, the array substrate 100 further includes a transistor M1, which is located between the first electrode 20 and the substrate 10 in a direction perpendicular to the plane where the display panel AA is located. The transistor M1 can be used as a component of the pixel circuit 50 or the shift register 60. The array substrate 100 further includes a transmitting line 304, which is electrically connected to the first touch electrode 301. The transmitting line 304 is used to transmit a signal of a specific frequency, so that a changing electric field is established between the first touch electrode 301 and the second touch electrode 302.

[0085] The transmitting wire 304 is located between the first touch electrode 301 and the substrate 10, and the film layer where the transmitting wire 304 is located is the same as the film layer where the transistor M1 is located. Optionally, the film layer where the transistor M1 is located includes an active layer M11 and a gate layer G1. The gate layer G1 of the transistor M1 can be used to receive a control signal to drive the transistor M1 to work, and the material of the gate layer G1 can be a metal material. Fig.17 As shown, the emitter trace 304 and the gate layer G1 can be fabricated in the same film layer.

[0086] In the embodiment of the present application, the emission line 304 is arranged in the same layer as the part of the film layer where the transistor M1 is located. This is beneficial to avoid the risk of increasing the film layer structure of the display panel AA by opening a separate film layer when setting the emission line 304, and is also beneficial to reducing the process preparation flow and improving the preparation efficiency of the display panel AA with a touch function.

[0087] Fig.18 Another embodiment provided in this application is Figure 1 Schematic diagram of the cross section along the A-A' direction.

[0088] In one embodiment of the present application, Figure 1 , Fig.18As shown, the array substrate 100 further includes a transistor M1, which is located between the first electrode 20 and the substrate 10. The array substrate 100 further includes a shielding structure 80, which is located between the transistor M1 and the substrate 10, and in a direction perpendicular to the plane where the display panel AA is located, the shielding structure 80 at least overlaps with the channel of the transistor M1. Optionally, the shielding structure 80 can be used as a gate of the transistor M1, so that the transistor M1 is a dual-gate transistor. The shielding structure 80 can also be used to prevent light from the substrate 10 toward the transistor M1 from being incident on the transistor M1, thereby ensuring the working stability of the transistor M1.

[0089] In the embodiment of the present application, the film layer where the transmitting wiring 304 is located is arranged to be on the same layer as the film layer where the shielding structure 80 is located, which is beneficial to reducing the complexity of the film layer structure of the display panel AA and reducing the thickness of the panel; in addition, the wiring complexity of the film layer where the shielding structure 80 is located is relatively low, so the electrical signal of the film layer is less affected. The transmitting wiring 304 is arranged to be on the same layer as the shielding structure 80, which is beneficial to improving the accuracy of the signal transmitted by the transmitting wiring 304, thereby improving the accuracy and sensitivity of the touch function.

[0090] Fig.19 Another embodiment provided in this application is Figure 1 Schematic diagram of the cross section along the A-A' direction.

[0091] In one embodiment of the present application, Figure 1 , Fig.19 As shown, the array substrate 100 further includes a transistor M1, which includes an active layer M11. In a direction perpendicular to the plane where the display panel AA is located, the active layer M11 is located between the first electrode 20 and the substrate 10; the array substrate 100 further includes a first metal layer 90. In a direction perpendicular to the plane where the display panel AA is located, the first metal layer 90 is located between the first electrode 20 and the active layer M11. The first metal layer 90 can be used to prepare a signal trace in the pixel circuit 50 or the shift register circuit 60 in the array substrate 100. The array substrate 100 further includes an emission trace 304. The emission trace 304 is electrically connected to the first touch electrode 301. As can be seen from the above embodiment, the emission trace 304 is used to transmit an electrical signal to the first touch electrode 301, so that an electric field is formed between the first touch electrode 301 and the second touch electrode 302.

[0092] In the embodiment of the present application, the transmitting wiring 304 is arranged between the first touch electrode 301 and the substrate 10, and the film layer where the transmitting wiring 304 is located is in the same layer as the partial film layer where the first metal layer 90 is located, which is beneficial to reducing the film layer structure thickness of the display panel AA, reducing the manufacturing complexity of the display panel AA, and improving the manufacturing efficiency of the display panel AA.

[0094] In one embodiment of the present application, Fig. 20 As shown, the transmitting line 304 is electrically connected to the plurality of first touch electrodes 301, which is conducive to the transmitting line 304 transmitting signals to the plurality of first touch electrodes 301 at the same time, reducing the number of transmitting lines 304, and is conducive to simultaneously providing an electric field between the plurality of first touch electrodes 301 and the second touch electrodes 302. In some technical solutions, the transmitting line 304 is electrically connected to the plurality of first touch electrodes 301, which is also conducive to increasing the touch area of ​​the touch unit in the display panel AA. Although the plurality of first touch electrodes 301 are separated by the light-emitting device 200, the use of the transmitting line 304 is conducive to connecting the plurality of first touch electrodes 301, preparing for increasing the touch area, thereby improving the sensitivity of the touch function.

[0095] Fig.21 Another embodiment provided in this application is Figure 1 Schematic diagram of a part of the middle area E1.

[0096] In one embodiment of the present application, Fig.21 As shown, the second touch electrode 302 includes a plurality of first portions 302A extending along the first direction X1 and arranged along the second direction X2, and the second touch electrode 302 also includes a second portion 302B extending along the second direction X2, and the first portion 302A and the second portion 302B are in the same layer. The second portion 302B connects the plurality of first portions 302A arranged along the second direction X2, and the first direction X1 and the second direction X2 intersect and are both parallel to the plane where the display panel AA is located. Fig.21 As shown, optionally, the transmitting trace 304 extends along the first direction X1 and is electrically connected to the first touch electrode 301 adjacent to the second direction X2. The second portion 302B of the second touch electrode 302 extends along the second direction X2 and overlaps with the first touch electrode 301 through the first portion 302A to form a mutual capacitance point.

[0097] In the embodiment of the present application, the first part 302A of the second touch electrode 302 is provided to at least simultaneously cover two adjacent first touch electrodes 301 in the first direction X1. Optionally, the size of the light emitting device 200 in the display panel AA is small, and a plurality of first touch electrodes 301 adjacent to some of the light emitting devices 200 may be used together to form a touch area Q1. For example, Fig.21 As shown, the touch area Q1 includes two first touch electrodes 301 adjacent to each other along the first direction X1 , and also includes a first portion 302A overlapping the first touch electrodes 301 .

[0098] It should be noted that the electrical connection method of the touch electrodes provided in the embodiment of the present application and the overlapping portion between the first touch electrode 301 and the second touch electrode 302 are exemplary solutions, and are not the only preparation method.

[0099] Fig. 22 A schematic plan view of another display panel provided in an embodiment of the present application is shown in FIG. Fig.23 A method provided in the embodiment of the present application Fig. 22 Schematic diagram of the cross section along the E-E' direction, Fig.24 A schematic plan view of another display panel provided in an embodiment of the present application is shown in FIG. Fig.25 A schematic plan view of another display panel provided in an embodiment of the present application.

[0100] In one embodiment of the present application, Fig. 22 , Fig.23 As shown, the display panel AA includes a pixel circuit 50, and the first electrode 20 includes a first type of first electrode 20A and a second type of first electrode 20B, and the second type of first electrode 20B is electrically connected to the pixel circuit 50. The array substrate 100 includes a first electrode 20, and the first electrode 20 is electrically connected to the connection electrode 40 of the light-emitting device 200, and is used to transmit a light-emitting signal to the light-emitting device 200. The unit that generates the above-mentioned light-emitting signal can be a pixel circuit 50, and the pixel circuit 50 transmits the generated light-emitting signal to the light-emitting device 200 through the first electrode 20. Since the second type of first electrode 20B is electrically connected to the pixel circuit 50, the light-emitting signal is output by the second type of first electrode 20B, so when the light-emitting device 200 generates different light-emitting brightness, the signal transmitted by the second type of first electrode 20B will also change accordingly. At this time, the first type of first electrode 20A can transmit a fixed electrical signal. Optionally, the first type of first electrode 20A is electrically connected to the cathode of the light-emitting device 200, and the second type of first electrode 20B is electrically connected to the anode of the light-emitting device 200.

[0101] The first type of first electrode 20A is adjacent to and not electrically connected to the second type of first electrode 20B, and the first type of first electrode 20A at least partially surrounds the second type of first electrode 20B. The connecting electrode 40 of the light emitting device 200 includes a first type of connecting electrode 40A and a second type of connecting electrode 40B, the first type of connecting electrode 40A of the light emitting device 200 is electrically connected to the first type of first electrode 20A, and the second type of connecting electrode 40B is electrically connected to the second type of first electrode 20B.

[0102] like Fig. 22 , Fig.23As shown, the display panel AA includes a second type first electrode group Q20B, and the second type first electrode group Q20B includes at least two second type first electrodes 20B arranged along the second direction X2. Optionally, a plurality of second type first electrodes 20A in the second type first electrode group Q20B are electrically connected to a plurality of light emitting devices 200 belonging to the same pixel, and the second type first connection electrodes 40B of the plurality of light emitting devices 200 are respectively electrically connected to the corresponding pixel circuits 50 driving them to emit light. In the display panel AA, a gap is included between two adjacent pixels in the first direction X1, and a gap is also included between two adjacent pixels in the second direction X2. Then, a gap is included between two adjacent second type first electrode groups Q20B in the first direction X1, and a gap is also included between two adjacent second type first electrode groups Q20B in the second direction X2.

[0103] The first touch electrode 301 is arranged in the above gap to fully utilize the space of the display panel AA, improve the space utilization of the display panel AA, and reduce the complexity of the film structure of the display panel AA. The first direction X1 and the second direction X2 are both parallel to the plane where the display panel AA is located, and the first direction X1 and the second direction X2 intersect.

[0104] Alternatively, if Fig. 22 As shown, the first touch electrodes 301 are arranged alternately with the second type first electrode groups Q20B in the first direction X1, so that the first touch electrodes 301 are located between two adjacent second type first electrode groups Q20B in the first direction X1. Optionally, the first type first electrode 20A is included between the adjacent second type first electrodes 20A and the first touch electrodes 301 in the first direction X1, which is conducive to reducing the risk of the first touch electrodes 301 being subjected to signal crosstalk.

[0105] Alternatively, if Fig.24 As shown, the first touch electrodes 301 are arranged alternately with the second-type first electrode groups Q20B in the second direction X2, so that the first touch electrodes 301 are located between two adjacent second-type first electrode groups Q20B in the second direction X2, which is beneficial to fully utilize the space between adjacent second-type first electrode groups Q20B and improve the space utilization of the display panel AA.

[0106] Alternatively, if Fig.25As shown, the first touch electrodes 301 are arranged alternately with the second type first electrode groups Q20A in the first direction X1 and / or in the second direction X2, so that the first touch electrodes 301 are included between two adjacent second type first electrode groups Q20B in the first direction X1 and between two adjacent second type first electrode groups Q20B in the second direction X2, which is beneficial to further improve the space utilization of the display panel AA, and is also beneficial to increase the number of first touch electrodes 301 prepared in the display panel AA, thereby facilitating the increase of the number of touch sensing points in the display panel AA, and further improving the sensitivity and reliability of the touch function of the display panel AA.

[0107] In one embodiment of the present application, continue to refer to Fig. 22 As shown, the first touch electrodes 301 are arranged alternately with the second type first electrode group Q20B in the first direction X1. The width of the second type first electrode group Q20B in the second direction X2 is D1, the distance between two adjacent second type first electrode groups Q20B in the second direction X1 is D2, and the extension length of the first touch electrodes 301 in the second direction X2 is L1, and D1≤L1<D1+D2.

[0108] In the embodiment of the present application, setting L1≤D1+D2 is conducive to providing a parameter reference for the length that can be prepared for the first touch electrode 301 in the second direction X2, and is also conducive to avoiding the situation where the same first touch electrode 301 overlaps with multiple adjacent second-type first electrode groups Q20B in the first direction X1 at the same time, thereby avoiding multiple different second-type first electrodes Q20 respectively causing different electric field effects on different positions of the first touch electrode 301, thereby reducing the risk of poor potential uniformity at different positions on the same first touch electrode 301. Moreover, when the first touch electrode 301 is set to an arbitrary length, it may also cause different first touch electrodes 301 to be adjacent to the same second-type first electrode Q20B group, which will cause different second-type first electrodes 20B in the same second-type first electrode group Q20B to be affected by different degrees of electric fields, thereby causing the light-emitting device 200 to have different degrees of color shift effects.

[0109] Fig.26 A schematic plan view of another display panel provided in an embodiment of the present application.

[0110] In one embodiment of the present application, Fig.26As shown, in the first direction X1, the first touch electrodes 301 overlap with the second type of first electrodes 20B one by one. It can be seen that the first touch electrodes 301 have a small area and overlap with the second type of first electrodes 20B in the first direction X1, which is conducive to further improving the potential uniformity of each position of the first touch electrodes 301, avoiding the simultaneous influence of a large number of second type first electrodes 20B on the first touch electrodes 301; it is also conducive to reducing the risk of color deviation of the second type first electrodes 20B due to different degrees of electric fields. It can be imagined that this is also conducive to further increasing the number of first touch electrodes 301, so that the density of touch units in the display panel AA is higher, and the touch sensitivity can be further improved.

[0111] In one embodiment of the present application, continue to refer to Fig. 22 , Fig.25 , Fig.26 As shown, in the first direction X1, the width of the first type of first electrode 20A is W1, and the width of the second type of first electrode 20B is W2, W1≥0.25*W2, when preparing the light-emitting device 200, the first electrode 20 is electrically connected to the connecting electrode 40 accordingly, and the first type of first electrode 20A and the second type of first electrode 20B are adjacent to each other in the first direction X1. Accordingly, the extension direction of the light-emitting device 200 along the first direction X1 can be the arrangement direction of the first type of connecting electrode 40A and the second type of connecting electrode 40B.

[0112] It can be seen from the contents mentioned in the above embodiments that the embodiments of the present application are described by taking the first type of first electrode 20A corresponding to the cathode and the second type of first electrode 20B corresponding to the anode as an example. The width of the second type of first electrode 20B is set to W2, and W1≥0.25*W2. It can be seen that when preparing the first electrode 20, the extension length of the second type of first electrode 20B in the first direction X1 can be set appropriately larger than the first type of first electrode 20A, which is conducive to setting a redundant position on the array substrate 100 and preparing for the supplementary light-emitting device 200. In addition, the present application sets W1≥0.25*W2, which is also conducive to avoiding the risk of increasing the impedance of the first type of first electrode 20A due to the extension length of the first type of first electrode 20A along the first direction X1 being too small, and is also conducive to providing sufficient space for the preparation of the light-emitting device 200, ensuring effective bonding between the connecting electrode 40 of the light-emitting device 200 and the first electrode 20.

[0113] Fig. 27 A schematic plan view of another display panel provided in an embodiment of the present application is shown in FIG. Fig.28 A schematic plan view of another display panel provided in an embodiment of the present application.

[0114] When the light emitting device 200 is prepared on the array substrate 100, optionally, as Fig. 22 , Figure 24-26 As shown, the light emitting devices 200 can be prepared in a row along the first direction X1. Figure 27-Figure 28 As shown, the light emitting device 200 can be prepared in a staggered manner along the first direction X1. It should be noted that a gap is included between the light emitting device 200 and the first touch electrode 301 during preparation, so as to avoid short circuit between the first touch electrode 301 and the electrode of the light emitting device 200.

[0115] In one embodiment of the present application, continue to refer to Fig. 22 , Fig.25 , Fig.26 As shown, the distance between the first type of first electrode 20A and the second type of first electrode 20B adjacent to each other in the first direction X1 is D3, and the distance between the first type of first electrode 20A and the first touch electrode 301 adjacent to each other in the first direction X1 is D4; D3 ≥ 3 μm, D4 ≥ 3 μm, which is conducive to ensuring that the first type of first electrode 20A and the second type of first electrode 20B are not connected and the insulation is effective, and is conducive to ensuring that the first type of first electrode 20A and the first touch electrode 301 are not connected and the insulation is effective.

[0117] The present application embodiment provides a display device 1AA, such as Fig.29 As shown, the display device 300 includes the display panel AA provided in the above embodiment. The display device 300 can be a mobile phone, computer, watch, television, or other device that can be used for display and touch.

[0118] In the display device 1AA, the first touch electrode 301 is arranged in the same layer as the first electrode 20, which is conducive to avoiding the situation where the first touch electrode 301 occupies a film layer alone, thereby helping to reduce the film thickness and the number of film layer structures of the display panel AA, and reducing the structural complexity of the display panel AA. In addition, it is also conducive to reducing the process of manufacturing the display panel AA and improving the manufacturing efficiency of the display panel AA.
