[0073] Embodiments of the present application provide a display panel, a display device, and a method for manufacturing a display panel. Embodiments of the display panel, the display device, and the method for manufacturing a display panel will be described below in conjunction with the accompanying drawings.

[0074] An embodiment of the present application provides a display panel, which may be an organic light emitting diode (OLED) display panel.

[0075] See also Figures 1 to 3 , Figure 1 is a cross-sectional schematic diagram of a display panel provided in an embodiment of the present application; Figure 2 is a partial cross-sectional view of a display panel provided in an embodiment of the present application; Figure 3 is a partial cross-sectional view of a display panel in another embodiment.

[0076] like Figures 1 to 3 As shown, the first aspect of the present application provides a display panel 10, the display panel 10 has a display area AA1 and a light-transmitting area AA2, the display panel 10 includes a substrate 100, an isolation structure 200 and a touch layer 300; the isolation structure 200 is located on one side of the substrate 100, the isolation structure 200 encloses an isolation opening 240 and a light-transmitting opening 250, the isolation opening 240 is located in the display area AA1, the isolation opening 240 is used to set the light-emitting unit 410, and the light-transmitting opening 250 is located in the light-transmitting area AA2; the touch layer 300 is located on the side of the isolation structure 200 away from the substrate 100, the touch layer 300 includes a first conductive layer 310 and a second conductive layer 320 stacked, the first conductive layer 310 includes touch electrodes 311 and virtual electrodes 312 spaced and insulated from each other, the virtual electrodes 312 include a first virtual electrode 313 at least partially located in the light-transmitting area AA2, the second conductive layer 320 includes a first connecting segment 321, and the first virtual electrode 313 is connected to a shielding signal through the first connecting segment 321.

[0077] According to the display panel 10 of an embodiment of the present application, the display panel 10 includes a substrate 100, an isolation structure 200, and a touch layer 300. The isolation structure 200 is disposed on the substrate 100 and encloses a plurality of isolation openings 240 for partitioning the light-emitting layer 400 to form mutually disconnected light-emitting units 410, thereby reducing the crosstalk of carriers in the light-emitting layer 400 and improving the display effect of the display panel 10. Moreover, when preparing the light-emitting units 410, a precision mask plate is not required, which can reduce the development and use of the precision mask plate and lower the manufacturing cost. A light-transmitting opening 250 is formed in the isolation structure 200, which can improve the transmittance of the display panel 10 in the light-transmitting region AA2. The touch layer 300 is located on a side of the isolation structure 200 away from the substrate 100 and includes touch electrodes 311 and virtual electrodes 312 that are insulated from each other at intervals. The touch electrodes 311 are used to implement the touch function of the display panel 10. The virtual electrodes 312 are insulated from the touch electrodes 311 at intervals, that is, the signals between the virtual electrodes 312 and the touch electrodes 311 are independent of each other. The virtual electrodes 312 include first virtual electrodes 313 at least partially located in the light-transmitting region AA2. The signal of the substrate 100 will interfere with the first virtual electrodes 313 through the light-transmitting opening 250. However, since the touch electrodes 311 and the virtual electrodes 312 are insulated from each other, the interference received by the touch electrodes 311 is small, improving the touch performance of the touch electrodes 311. The virtual electrodes 312 and the touch electrodes 311 are located in a first conductive layer 310. The second conductive layer 320 includes a first connection segment 321. The first virtual electrodes 313 are connected to the first connection segment 321 through vias and are connected to a shielding signal through the first connection segment 321, so that the first virtual electrodes 313 have a fixed shielding signal. When the first virtual electrodes 313 are interfered by signals from the light-transmitting opening 250, the potential of the first virtual electrodes 313 is stable and difficult to change, so as to improve the problem that the potential change of the first virtual electrodes 313 after being interfered causes the touch signals of the touch electrodes 311 to be coupled with each other, affecting the signal stability of the touch electrodes 311, that is, reducing the mutual interference between the data signal of the substrate 100 and the touch signal of the touch electrodes 311 through the light-transmitting opening 250, thereby improving the service performance of the OLED display product.

[0078] Optionally, some of the isolation openings 240 are located in the light-transmitting region AA2. The light-emitting units 410 are also arranged in the isolation openings 240 in the light-transmitting region AA2, so that the light-transmitting region AA2 has a display function, realizing the full display of the display panel 10.

[0079] There are also various ways to set the substrate 100. For example, the substrate 100 may include a substrate and an array substrate disposed on the substrate. Or the substrate 100 is the substrate itself. Or the substrate 100 includes a buffer layer and a support plate on a side away from the substrate, etc.

[0080] Optionally, the substrate 100 includes data signal lines for providing data signals to the devices of the display panel 10.

[0081] Please refer to Figure 4 , Figure 4 which is a top view schematic diagram of the display panel in another embodiment.

[0082] As Figure 4 shown, in some alternative embodiments, the display panel 10 has a non-display area NA disposed around at least a portion of the display area AA1. The display panel 10 further includes shield signal traces 316, at least a portion of the shield signal traces 316 being located in the non-display area NA. One end of the shield signal traces 316 is connected to the first connection segment 321, and the other end is for connecting to a shield signal.

[0083] In these alternative embodiments, at least a portion of the shield signal traces 316 is located in the non-display area NA to reduce the influence of the shield signal traces 316 on the light emission of the display area AA1 and ensure the light emission effect of the display area AA1. One end of the shield signal traces 316 is connected to the first connection segment 321, and the other end is for connecting to a shield signal, such that the first virtual electrode 313 can be connected to the shield signal through the first connection segment 321, ensuring that the first virtual electrode 313 has a stable fixed potential.

[0084] Optionally, at least one first virtual electrode 313 is disposed adjacent to the non-display area NA. One end of the shield signal traces 316 is electrically connected to the first virtual electrode 313, and the other end is for connecting to a shield signal. The first virtual electrode 313 disposed adjacent to the non-display area NA can be directly electrically connected to the shield signal traces 316, thereby providing a shield signal for the first virtual electrode 313.

[0085] In some alternative embodiments, the shield signal traces 316 include a first trace located in the first conductive layer 310. At least one first virtual electrode 313 is disposed adjacent to the non-display area NA. One end of the first trace is connected to the first virtual electrode 313, and the other end is for connecting to a shield signal.

[0086] In these alternative embodiments, the first virtual electrode 313 disposed adjacent to the non-display area NA can be directly electrically connected to the first trace, thereby providing a shield signal for the first virtual electrode 313. The first virtual electrode 313 and the first trace are both located in the first conductive layer 310 and can be directly overlapped, simplifying the manufacturing process.

[0087] In some alternative embodiments, the shield signal traces 316 include a second trace located in the second conductive layer 320. One end of the second trace is connected to the first connection segment 321, and the other end is for connecting to a shield signal.

[0088] In these alternative embodiments, after the first virtual electrode 313 is connected to the first connection segment 321 through a via, the first connection segment 321 can be directly electrically connected to the second trace, thereby providing a shielding signal for the first virtual electrode 313. Both the first connection segment 321 and the second trace are located in the second conductive layer 320 and can be directly overlapped, simplifying the manufacturing process.

[0089] In some alternative embodiments, the shielding signal trace 316 is connected to the shielding signal of the integrated circuit.

[0090] In these alternative embodiments, the integrated circuit provides a shielding signal for the first virtual electrode 313, so that the first virtual electrode 313 has a fixed shielding signal. When the first virtual electrode 313 is interfered by the signal from the light-transmitting opening 250, the potential of the first virtual electrode 313 is stable and difficult to change, so as to improve the problem that the potential change of the first virtual electrode 313 after being interfered causes the mutual coupling of the touch signals with the touch electrode 311, affecting the signal stability of the touch electrode 311.

[0091] Optionally, the shielding signal includes a fixed voltage signal, so that the first virtual electrode 313 has a fixed potential, is relatively stable, and is difficult to change its potential after being interfered.

[0092] Optionally, the fixed voltage signal is a ground voltage signal. The integrated circuit provides a ground signal for the first virtual electrode 313, so that the first virtual electrode 313 is grounded. After the touch signal or data signal causes a charge perturbation to the first virtual electrode 313, the coupled electrons generated by the first virtual electrode 313 can be released to the ground, maintaining a state of constant potential without being interfered. Therefore, it is difficult for the touch signal and the data signal to affect each other through the first virtual electrode 313, thereby further reducing the mutual interference of the touch signal and the data signal through the light-transmitting opening 250.

[0093] In some alternative embodiments, the first conductive layer 310 further includes a touch trace 315. At least part of the touch trace 315 is located in the non-display area NA. One end of the touch trace 315 is connected to the touch electrode 311, and the other end is used to connect to the integrated circuit.

[0094] In these alternative embodiments, at least part of the touch trace 315 is located in the non-display area NA to reduce the light-emitting influence of the touch trace 315 on the display area AA1 and ensure the light-emitting effect of the display area AA1. One end of the touch trace 315 is used to connect to the integrated circuit, and the other end is connected to the touch electrode 311. The integrated circuit provides a touch signal for the touch electrode 311 to realize the touch function of the touch electrode 311.

[0095] In some alternative embodiments, the shielding signal trace 316 and the touch trace 315 are separately disposed on both sides of the display area AA1.

[0096] In these alternative embodiments, the shielding signal trace 316 and the touch trace 315 are disposed in the non-display area NA on both sides of the display area AA1. Both the shielding signal trace 316 and the touch trace 315 have a relatively large routing space, facilitating the routing of the shielding signal trace 316 and the touch trace 315, and improving the problem that when both the shielding signal trace 316 and the touch trace 315 are located in the non-display area NA on one side of the display area AA1, the shielding signal trace 316 and the touch trace 315 conflict with each other and are short-circuited. Moreover, the signals of the shielding signal trace 316 and the touch trace 315 are difficult to affect each other, ensuring the stability of the signals of the shielding signal trace 316 and the touch trace 315.

[0097] Please refer to Figure 4 and Figure 5 , Figure 5 which is a top view schematic diagram of the display panel in another embodiment. Figure 5 For the sake of clearly showing some structures, structures such as the touch electrode 311 are omitted and not shown in the figure.

[0098] In some alternative embodiments, as Figure 4 shown, the first connection segment 321 connects multiple first virtual electrodes 313 in the same light-transmitting area AA2, and / or, as Figure 5 shown, the first connection segment 321 connects the first virtual electrodes 313 located in multiple different light-transmitting areas AA2.

[0099] In these alternative embodiments, the first virtual electrodes 313 are electrically connected to form a whole. After the multiple first virtual electrodes 313 are connected to each other, only a single trace is required to ground the first virtual electrodes 313 as a whole, reducing the number of traces and simplifying the manufacturing process.

[0100] In some alternative embodiments, one or more first virtual electrodes 313 are located in the same light-transmitting area AA2.

[0101] In these alternative embodiments, the electrodes in the touch layer 300 located in the light-transmitting area AA2 are the first virtual electrodes 313. The light-transmitting area AA2 can be larger than the first virtual electrode 313, that is, the first virtual electrode 313 is completely located within the light-transmitting area AA2. The light-transmitting area AA2 can be smaller than the first virtual electrode 313, that is, only a part of the first virtual electrode 313 is located within the light-transmitting area AA2.

Figure 6To clearly illustrate some structures, structures such as the touch electrode 311 are omitted and not shown in the figure.

[0103] In some alternative embodiments, as Figure 4 shown, a plurality of first virtual electrodes 313 distributed along the first direction X are bridged and connected through a first connection segment 321; and / or, as Figure 6 and Figure 7 shown, the virtual electrode 312 further includes a second virtual electrode 314 located in the display area AA1, the first virtual electrode 313 is bridged and connected to the second virtual electrode 314 through the first connection segment 321, and the second virtual electrode 314 is electrically connected to a shielding signal.

[0104] In these alternative embodiments, a plurality of first virtual electrodes 313 are bridged and connected through the first connection segment 321 to form an integral body, or the first virtual electrode 313 is connected to the second virtual electrode 314 in the display area AA1 through the first connection segment 321, and then electrically connected to the shielding signal through the second virtual electrode 314. Since the second virtual electrodes 314 are distributed throughout the display area AA1, at least some of the connections between the second virtual electrodes 314 and the shielding signal are easier than the connections between the first virtual electrodes 313 and the shielding signal, so as to reduce the manufacturing difficulty and simplify the manufacturing process.

[0105] Optionally, a plurality of first virtual electrodes 313 distributed along the first direction X are located in the same row, so that the first virtual electrodes 313 in the same row are connected in the first direction X, that is, the first connection segment 321 extends in the first direction X, so as to reduce conflicts with other traces extending in the first direction X located in the second conductive layer 320.

[0106] Optionally, at least one second virtual electrode 314 is in the same row as the first virtual electrode 313 in the first direction X. When the first virtual electrode 313 is electrically connected to the shielding signal through the second virtual electrode 314, the first virtual electrode 313 and the second virtual electrode 314 are in the same row, so that the first connection segment 321 connecting the first virtual electrode 313 and the second virtual electrode 314 extends in the first direction X, so as to reduce conflicts with other traces extending in the first direction X located in the second conductive layer 320.

[0107] Please refer to Figure 8 and Figure 9 , Figure 8 which is a partial cross-sectional view of a display panel in yet another embodiment; Figure 9 which is a top view schematic diagram of a display panel in still another embodiment.

[0108] As Figure 8 and Figure 9As shown, in some alternative embodiments, the touch electrode 311 includes a touch driving electrode 318 and a touch sensing electrode 319. The second conductive layer 320 includes a second connection segment 322 extending along the first direction X. A plurality of touch sensing electrodes 319 distributed along the first direction X are cross-bridged through the second connection segment 322. A plurality of touch driving electrodes 318 distributed along the second direction Y are electrically connected to each other within the first conductive layer 310. The first direction X and the second direction Y intersect.

[0109] In these alternative embodiments, the touch driving electrode 318 and the touch sensing electrode 319 are distributed along the first direction X and the second direction Y to form a mutual capacitance type touch display panel 10.

[0110] In some alternative embodiments, the first conductive layer 310 includes a third connection segment extending along the second direction Y. A plurality of touch driving electrodes 318 distributed along the second direction Y are electrically connected to each other through the third connection segment. The orthographic projection of the first connection segment 321 on the substrate 100 overlaps with the orthographic projection of the third connection segment on the substrate 100.

[0111] In these alternative embodiments, one end of the first connection segment 321 is connected to a first virtual electrode 313 and simultaneously spans across the touch driving electrode 318 to be connected to the first virtual electrode 313 on the other side of the touch driving electrode 318.

[0112] Optionally, the touch electrode 311 is disposed around the virtual electrode 312. A touch electrode 311 is disposed between adjacent virtual electrodes 312. The virtual electrodes 312 are cross-bridged through the first connection segment 321 of different layers to prevent the first trace segment 321 from conflicting with the touch electrode 311.

[0113] Optionally, the first virtual electrode 313 is located within the touch sensing electrode 319, that is, the touch sensing electrode 319 is disposed around the first virtual electrode 313, such that the first virtual electrode 313 and the touch sensing electrode 319 have the same distribution direction, and the first connection segment 321 and the second connection segment 322 have the same extending direction, so that the first connection segment 321 and the second connection segment 322 do not conflict, improving the reliability of the first connection segment 321 and the second connection segment 322.

[0114] In some alternative embodiments, the orthographic projections of the touch electrode 311 and the virtual electrode 312 on the substrate 100 are located outside the orthographic projection of the light-transmitting opening 250 on the substrate 100.

[0115] In these alternative embodiments, both the touch electrode 311 and the virtual electrode 312 are disposed in a dislocation manner with respect to the light-transmitting opening 250 to prevent the touch electrode 311 and the virtual electrode 312 from blocking the light-transmitting opening 250 and ensure the transmittance of the light-transmitting opening 250.

[0116] Optionally, at least a part of the touch electrodes 311 and the virtual electrodes 312 are located within the orthographic projection of the isolation structure 200 on the substrate 100, reducing the occlusion of the touch electrodes 311 and the virtual electrodes 312 on the light-transmitting openings 250 and other light-transmitting parts, such as the pixel defining part 610, and improving the overall transmittance of the display panel 10.

[0117] In some alternative embodiments, the virtual electrode 312 includes a third virtual electrode 317 located in the display area AA1, and each third virtual electrode 317 is suspended.

[0118] The third virtual electrode 317 being suspended means that the third virtual electrode 317 is not connected to other virtual electrodes 312, touch electrodes 311, and traces, and is an independent and non-powered structure.

[0119] In these alternative embodiments, the setting of the third virtual electrode 317 enables virtual electrodes 312 to be provided at all positions of the display panel 10, improving the uniformity of touch and display.

[0120] Please refer to Figure 10 , Figure 10 which is a partial cross-sectional view of the display panel in yet another embodiment.

[0121] As Figure 10 shown, in some alternative embodiments, the display panel 10 further includes a light-emitting layer 400 and a first electrode layer 500. The light-emitting layer 400 is located on one side of the substrate 100, and the light-emitting layer 400 includes light-emitting units 410 located in the isolation openings 240; the first electrode layer 500 is located on the side of the light-emitting layer 400 away from the substrate 100.

[0122] Optionally, the first electrode layer 500 includes a first electrode 510 located in the isolation opening 240, and the first electrode 510 is electrically connected to the isolation structure 200.

[0123] In these alternative embodiments, the isolation structure 200 partitions the first electrode layer 500 to form spaced-apart first electrodes 510, and the spaced-apart first electrodes 510 are electrically connected through the isolation structure 200 to form a whole-surface electrode, ensuring the normal light emission of the light-emitting units 410.

[0124] In some alternative embodiments, the orthographic projection of each light-emitting unit 410 on the substrate 100 is located within the orthographic projection of each first electrode 510 on the substrate 100.

[0125] In these alternative embodiments, the orthographic projection of the light-emitting unit 410 on the substrate 100 is located within the orthographic projection of the first electrode 510 on the substrate 100, that is, the first electrode 510 covers the light-emitting unit 410 to serve as the electrode of the light-emitting unit 410, ensuring the normal light emission of the light-emitting unit 410 and improving the display effect of the display panel 10.

[0126] Optionally, the light-emitting units 410 are spaced apart from the isolation structure 200, and the light-emitting units 410 and the isolation structure 200 are spaced apart, that is, the light-emitting units 410 are spaced apart from each other, reducing the crosstalk of carriers between the light-emitting units 410 and improving the color bleeding problem of the light-emitting units 410.

[0127] In some alternative embodiments, the isolation structure 200 includes a first layer 210 and a second layer 220 located on the side of the first layer 210 away from the substrate 100, and the orthographic projection of the first layer 210 on the substrate 100 is located within the orthographic projection of the second layer 220 on the substrate 100.

[0128] In these alternative embodiments, the first layer 210 and the second layer 220 are arranged to form the isolation structure 200. The orthographic projection of the first layer 210 close to the substrate 100 on the substrate 100 is located within the orthographic projection of the second layer 220 on the substrate 100. The area of the second layer 220 is larger than that of the first layer 210, and the second layer 220 covers the surface of the first layer 210 close to the second layer 220. At this time, the first layer 210 is recessed relative to the second layer 220 in the direction away from the isolation opening 240. When preparing the light-emitting layer 400, a large drop occurs at the edge of the isolation structure 200, and the first layer 210 is concave relative to the second layer 220, making it difficult for the light-emitting layer 400 to connect at the edge of the isolation structure 200, resulting in breakage. The light-emitting layer 400 breaks to form mutually disconnected light-emitting units 410.

[0129] In some alternative embodiments, the second layer 220 includes a conductive material or an insulating material.

[0130] In these alternative embodiments, the second layer 220 includes a conductive material. For example, the second layer 220 includes a non-metallic conductive material or a metallic conductive material. When the second layer 220 is a non-metallic conductive material or an insulating material, it is difficult to etch the second layer 220 during the wet etching of the first layer 210 with an etching solution, making it easier for the first layer 210 to be recessed relative to the second layer 220.

[0131] In some alternative embodiments, the second layer 220 includes a metallic material, and the materials of the first layer 210 and the second layer 220 are different.

[0132] In these alternative embodiments, when both the first layer 210 and the second layer 220 are made of metal materials, a wet etching process can be used to etch the first layer 210 with an etching solution. By setting the etching solution, the etching rate of the second layer 220 can be made less than that of the first layer 210. Since the etching rate of the first layer 210 is relatively high, when wet etching is performed with the etching solution, even though the second layer 220 will be etched to some extent, the first layer 210 is etched faster, resulting in the first layer 210 being recessed relative to the second layer 220.

[0133] In some alternative embodiments, the isolation structure 200 further includes a third layer 230 on the side of the first layer 210 facing the substrate 100. The orthographic projection of the first layer 210 on the substrate 100 is within the orthographic projection of the third layer 230 on the substrate 100.

[0134] In these alternative embodiments, in order to obtain the recessed first layer 210, during the etching process, the first layer 210 has a relatively high etching rate relative to the second layer 220 and the third layer 230, thereby forming the recessed first layer 210. Since the etching rate of the first layer 210 is relatively high, more etching waste is generated and is likely to enter other positions of the display panel 10, thereby causing adverse effects. After the third layer 230 is provided, the first layer 210 can be better attached to the third layer 230, and the generated etching waste falls on the third layer 230, facilitating cleaning.

[0135] In some alternative embodiments, the display panel 10 further includes a pixel definition layer 600 located on the substrate 100. The pixel definition layer 600 includes pixel defining portions 610 and pixel openings 620 formed by enclosing the pixel defining portions 610. The light emitting units 410 are located in the pixel openings 620, and the pixel openings 620 communicate with the isolation openings 240.

[0136] In these alternative embodiments, the pixel openings 620 formed by enclosing the pixel defining portions 610 are used to set the light emitting units 410 to achieve the light emitting display of the display panel 10. The pixel openings 620 and the isolation openings 240 are communicatively arranged to reduce the occlusion of the isolation structure 200 on the pixel openings 620 and ensure the light emitting effect of the light emitting units 410.

[0137] Optionally, the display panel 10 further includes a pixel electrode 640 exposed by the pixel openings 620. One of the pixel electrode 640 and the first electrode 510 serves as the anode of the light emitting unit 410, and the other serves as the cathode of the light emitting unit 410. In the embodiments of the present application, an example is given where the pixel electrode 640 serves as the anode of the light emitting unit 410 and the first electrode 510 serves as the cathode of the light emitting unit 410.

[0138] In some alternative embodiments, the isolation structure 200 is located on a side of the pixel defining portion 610 away from the substrate 100.

[0139] In these alternative embodiments, the isolation structure 200 is disposed on the pixel defining portion 610. The isolation structure 200 has a relatively large height difference with respect to the pixel opening 620. When preparing the light emitting layer 400, due to the large height difference, the light emitting layer 400 is more likely to break at the position of the isolation structure 200, reducing the difficulty of preparing the light emitting layer 400.

[0140] In some alternative embodiments, a receiving opening 630 is formed in the pixel defining portion 610, and the isolation structure 200 is located in the receiving opening 630.

[0141] In these alternative embodiments, the isolation structure 200 is disposed in the receiving opening 630 formed on the pixel defining portion 610. During the preparation process, the preparation step of the isolation structure 200 is before the preparation of the pixel electrode 640. That is, after the isolation structure 200 is prepared on the substrate 100, the pixel electrode 640 is then prepared on the substrate 100 to reduce the influence of the preparation of the isolation structure 200 on the pixel electrode 640 and ensure that the pixel electrode 640 is not damaged.

[0142] Optionally, the orthographic projections of the touch electrode 311 and the virtual electrode 312 on the substrate 100 are located outside the orthographic projection of the pixel opening 620 on the substrate 100. The touch electrode 311 and the virtual electrode 312 are both arranged in a misaligned manner with respect to the pixel opening 620 to prevent the touch electrode 311 and the virtual electrode 312 from blocking the pixel opening 620, so as to ensure the normal light emission of the light emitting unit 410.

[0143] In some alternative embodiments, the display panel 10 further includes a packaging layer 700, and the packaging layer 700 is located between the first electrode layer 500 and the touch layer 300.

[0144] In these alternative embodiments, the packaging layer 700 is disposed on a side of the first electrode layer 500 away from the substrate 100 to package the first electrode 510 and the light emitting layer 400, reducing the possibility of water and oxygen intrusion and improving the service life of the display panel 10.

[0145] Optionally, the light emitting layer 400 includes an electron injection layer (EIL), an electron transport layer (ETL), a light emitting material layer, a hole injection layer (HIL), and a hole transport layer (HTL).

[0146] According to a second aspect of the present application, a display panel 10 is provided. The display panel 10 has a display area AA1 and a light-transmitting area AA2. The display panel 10 further includes a substrate 100, an isolation structure 200, and a touch layer 300. The isolation structure 200 is located on one side of the substrate 100. The isolation structure 200 encloses an isolation opening 240 and a light-transmitting opening 250. The isolation opening 240 is located in the display area AA1. The isolation opening 240 is used to set a light-emitting unit 410. The light-transmitting opening 250 is located in the light-transmitting area AA2. The touch layer 300 Located on the side of the isolation structure 200 facing away from the substrate 100, the touch layer 300 includes a first conductive layer 310 and a second conductive layer 320 which are stacked, the first conductive layer 310 includes touch electrodes 311 and virtual electrodes 312 which are spaced and insulated from each other, there are multiple virtual electrodes 312, at least one of the multiple virtual electrodes 312 overlaps with the light-transmitting area AA2, the second conductive layer 320 includes a first connecting segment 321, and the multiple virtual electrodes 312 are bridged by the first connecting segment 321.

[0147] According to the display panel 10 of the embodiment of the present application, the display panel 10 includes a substrate 100, an isolation structure 200 and a touch layer 300. The isolation structure 200 is arranged on the substrate 100 and encloses a plurality of isolation openings 240, which are used to separate the light-emitting layer 400 to form mutually disconnected light-emitting units 410, thereby reducing the crosstalk of carriers in the light-emitting layer 400, improving the display effect of the display panel 10, and the preparation of the light-emitting unit 410 does not require the use of a precision mask plate, which can reduce the development and use of precision masks and reduce the preparation cost. A light-transmitting opening 250 is provided on the isolation structure 200, which can improve the transmittance of the display panel 10 in the light-transmitting area AA2. The touch layer 300 is located on the side of the isolation structure 200 away from the substrate 100 and includes a touch electrode 311 and a virtual electrode 312 that are spaced and insulated from each other. The touch electrode 311 is used to realize the touch function of the display panel 10. The virtual electrode 312 and the touch electrode 311 are spaced and insulated from each other, that is, the signals between the virtual electrode 312 and the touch electrode 311 are independent of each other. At least part of the virtual electrode 312 is located in the light-transmitting area AA2. The signal of the substrate 100 will interfere with the virtual electrode 312 through the light-transmitting opening 250, but the touch electrode 311 and the virtual electrode 312 are insulated from each other, so that the touch electrode 311 is less interfered, thereby improving the touch performance of the touch electrode 311. Each virtual electrode 312 is electrically connected to form a whole through the first connecting section 321. When multiple first virtual electrodes 313 are connected to each other, only a single wiring is required to ground the first virtual electrode 313 as a whole, thereby reducing the number of wirings and simplifying the preparation process.

[0148] The structural design in this embodiment can be applied to other display panels 10 , and the specific selection can be made according to actual conditions, and this application does not impose any specific restrictions on it.

[0149] Please refer to Figure 11 , Figure 11 which is a top view schematic diagram of a display device provided by an embodiment of the present application.

[0150] As Figure 11 shown, an embodiment of the third aspect of the present application further provides a display device, including the display panel 10 and the integrated circuit 800 (Integrated Circuit, IC) of any one of the above-mentioned first and second aspect embodiments. The integrated circuit 800 is electrically connected to both the virtual electrode 312 and the touch electrode 311, and provides a low signal for the virtual electrode 312 and a touch signal for the touch electrode 311. Since the display device provided by the embodiment of the third aspect of the present application includes the display panel 10 of any one of the above-mentioned first and second aspect embodiments, the display device provided by the embodiment of the third aspect of the present application has the beneficial effects of the display panel 10 of any one of the above-mentioned first and second aspect embodiments, which will not be elaborated herein.

[0151] The display device in the embodiment of the present application includes, but is not limited to, devices with a display function such as mobile phones, personal digital assistants (Personal Digital Assistant, abbreviated as: PDA), tablet computers, e-books, televisions, access control systems, smart landline phones, consoles, etc.

[0152] An embodiment of the fourth aspect of the present application further provides a method for manufacturing a display panel 10. The display panel 10 may be the display panel 10 provided by any one of the above-mentioned first aspect embodiments. Please refer to Figures 1 to 11 together. The display panel 10 has a display area AA1 and a light-transmitting area AA2. The manufacturing method includes:

[0153] Preparing an isolation structure 200 on a substrate 100. The isolation structure 200 encloses an isolation opening 240 and a light-transmitting opening 250. The isolation opening 240 is located in the display area AA1 and is used to set the light-emitting unit 410. The light-transmitting opening 250 is located in the light-transmitting area AA2.

[0154] Preparing a touch layer on a side of the isolation structure 200 away from the substrate 100. The touch layer 300 includes a first conductive layer 310 and a second conductive layer 320 stacked. The first conductive layer 310 includes a touch electrode 311 and a virtual electrode 312 that are spaced apart and insulated from each other. The virtual electrode 312 includes a first virtual electrode 313 that is at least partially located in the light-transmitting area AA2. The second conductive layer 320 includes a first connection segment 321. The first virtual electrode 313 is connected to a shielding signal through the first connection segment 321.

[0155] According to the preparation method of the third aspect embodiment of the present application, an isolation structure 200 is prepared on a substrate 100. The isolation structure 200 is disposed on the substrate 100 and encloses a plurality of isolation openings 240, which are used to partition the light-emitting layer 400 to form mutually disconnected light-emitting units 410, thereby reducing the crosstalk of carriers in the light-emitting layer 400 and improving the display effect of the display panel 10. Moreover, when preparing the light-emitting units 410, there is no need to use a precision mask plate, which can reduce the development and use of the precision mask plate and lower the preparation cost. A light-transmitting opening 250 is formed in the isolation structure 200, which can improve the transmittance of the display panel 10. A touch control layer is prepared. The touch control layer 300 is located on the side of the isolation structure 200 away from the substrate 100 and includes mutually insulated touch control electrodes 311 and virtual electrodes 312 spaced apart from each other. The touch control electrodes 311 are used to implement the touch control function of the display panel 10. The virtual electrodes 312 are insulated from the touch control electrodes 311, that is, the signals between the virtual electrodes 312 and the touch control electrodes 311 are independent of each other. The virtual electrodes 312 include first virtual electrodes 313 at least partially located in the light-transmitting region AA2. The data signal of the substrate 100 will interfere with the first virtual electrodes 313 through the light-transmitting opening 250. However, since the touch control electrodes 311 and the virtual electrodes 312 are insulated from each other, the interference received by the touch control electrodes 311 is small, improving the touch control performance of the touch control electrodes 311. The virtual electrodes 312 and the touch control electrodes 311 are located in a first conductive layer 310. The second conductive layer 320 includes a first connection segment 321. The first virtual electrodes 313 are connected to the first connection segment 321 through vias and are connected to a shielding signal through the first connection segment 321, so that the first virtual electrodes 313 have a fixed shielding signal. When the first virtual electrodes 313 are interfered by the signal from the light-transmitting opening 250, the potential of the first virtual electrodes 313 is stable and difficult to change, so as to improve the problem that the potential change of the first virtual electrodes 313 after being interfered causes the touch control signals of the touch control electrodes 311 to be coupled with each other, affecting the signal stability of the touch control electrodes 311, that is, reducing the mutual interference between the data signal of the substrate 100 and the touch control signal of the touch control electrodes 311 through the light-transmitting opening 250, thereby improving the service performance of the OLED display product.
