[0015] 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 disposed on the substrate 100 and surrounds it to form a plurality of isolation openings 240, which are used to block the light-emitting layer 400 to form the light-emitting units 410 separated from each other, thereby reducing the crosstalk of carriers in the light-emitting layer 400, improving the display effect of the display panel 10, and eliminating the need to use precision masks to manufacture the light-emitting units 410, reducing the development and use of precision masks, and reducing manufacturing costs. The isolation structure 200 has a light-transmitting opening 250, 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 dummy electrode 312 that are spaced apart and insulated from each other, the touch electrode 311 is used to realize the touch function of the display panel 10, and the dummy electrode 312 and the touch electrode 311 are spaced apart and insulated from each other, that is, signals between the dummy electrode 312 and the touch electrode 311 are independent from each other. The dummy electrode 312 includes a first dummy electrode 313 at least a part of which is located in the light-transmitting area AA2, and a signal from the substrate 100 interferes with the first dummy electrode 313 through the light-transmitting opening 250, but the touch electrode 311 and the dummy electrode 312 are insulated from each other, so that the interference experienced by the touch electrode 311 is small, and the touch performance of the touch electrode 311 is improved.The dummy electrode 312 and the touch electrode 311 are located on the first conductive layer 310, the second conductive layer 320 includes a first connection portion 321, the first dummy electrode 313 is connected to the first connection portion 321 by a via, and a shield signal is connected through the first connection portion 321, so that the first dummy electrode 313 has a fixed shield signal, and when the first dummy electrode 313 is interfered with by a signal from the light-transmitting opening 250, the potential of the first dummy electrode 313 is stable and difficult to change, and the touch signal with the touch electrode 311 is coupled to each other due to the potential change after the first dummy electrode 313 is interfered with, thereby improving the problem of affecting the stability of the signal of the touch electrode 311, that is, the mutual interference between the data signal of the substrate 100 and the touch signal of the touch electrode 311 caused by the light-transmitting opening 250 is reduced, and the usage performance of the OLED display product is improved.

[0016] Optionally, some of the isolated openings 240 are located in the light-transmitting area AA2, and the isolated openings 240 in the light-transmitting area AA2 are also used to install the light-emitting units 410, so that the light-transmitting area AA2 has a display function and realizes the full-surface display of the display panel 10.

[0018] Optionally, the substrate 100 includes data signal lines, which are used to provide data signals to the devices of the display panel 10 .

[0019] Referring to FIG. 4, FIG. 4 is a schematic plan view of a display panel according to another embodiment.

[0020] As shown in FIG. 4, in some optional embodiments, the display panel 10 has a non-display area NA surrounding at least a portion of the display area AA1, and the display panel 10 further includes a shield signal wiring 316, at least a portion of the shield signal wiring 316 is located in the non-display area NA, and the shield signal wiring 316 has one end connected to the first connection portion 321 and the other end used for connecting a shield signal.

[0021] In these optional embodiments, at least a part of the shield signal wiring 316 is located in the non-display area NA, thereby reducing the luminous influence of the shield signal wiring 316 on the display area AA1 and ensuring the luminous effect of the display area AA1. The shield signal wiring 316 has one end connected to the first connection portion 321 and the other end connected to the shield signal, and the first dummy electrode 313 is connected to the shield signal via the first connection portion 321 to ensure a stable fixed potential of the first dummy electrode 313.

[0022] Optionally, at least one first dummy electrode 313 is provided adjacent to the non-display area NA, and one end of the shield signal wiring 316 is electrically connected to the first dummy electrode 313 and the other end is used to connect the shield signal. The first dummy electrode 313 arranged adjacent to the non-display area NA can be directly electrically connected to the shield signal wiring 316 to provide the shield signal to the first dummy electrode 313.

[0023] In some alternative embodiments, the shield signal wiring 316 includes a first wiring located on the first conductive layer 310, and at least one first dummy electrode 313 is provided adjacent to the non-display area NA, and the first wiring has one end connected to the first dummy electrode 313 and the other end used to connect the shield signal.

[0024] In these optional embodiments, the first dummy electrode 313 located adjacent to the non-display area NA can be directly electrically connected to the first wiring, thereby providing a shielding signal to the first dummy electrode 313, and the first dummy electrode 313 and the first wiring can both be located on the first conductive layer 310 and directly connected to each other, thereby simplifying the manufacturing process.

[0025] In some alternative embodiments, the shielding signal wiring 316 includes a second wiring located on the second conductive layer 320, the second wiring having one end connected to the first connection portion 321 and the other end used to connect the shielding signal.

[0026] In these optional embodiments, after the first dummy electrode 313 and the first connection portion 321 are connected by a via, the first connection portion 321 can be directly electrically connected to the second wiring, thereby providing a shielding signal to the first dummy electrode 313, and the first connection portion 321 and the second wiring are both located on the second conductive layer 320 and can be directly overlapped and connected to simplify the manufacturing process.

[0027] In some alternative embodiments, the shield signal trace 316 connects the shield signal of the integrated circuit.

[0028] In these optional embodiments, the integrated circuit provides a shield signal to the first dummy electrode 313, so that the first dummy electrode 313 has a fixed shield signal. When the first dummy electrode 313 is interfered with by a signal from the light-transmitting opening 250, the potential of the first dummy electrode 313 is stable and not easily changed, which improves the problem that after the first dummy electrode 313 is interfered with, the potential change occurs and the touch signal with the touch electrode 311 is coupled to each other, affecting the stability of the signal of the touch electrode 311.

[0029] Optionally, the shield signal includes a fixed voltage signal, so that the first dummy electrode 313 has a fixed potential and is relatively stable, and is less likely to undergo potential changes after being subjected to interference.

[0030] Optionally, the fixed voltage signal is a ground voltage signal. The integrated circuit provides a ground signal to the first dummy electrode 313 to realize grounding of the first dummy electrode 313, and after the touch signal or the data signal disturbs the charge in the first dummy electrode 313, the coupling electrons generated by the first dummy electrode 313 are discharged to the ground, so that the potential can be kept fixed and uninterfered. Therefore, the touch signal and the data signal are unlikely to affect each other through the first dummy electrode 313, and thus the mutual interference between the touch signal and the data signal due to the light transmitting opening 250 is further reduced.

[0031] In some optional embodiments, the first conductive layer 310 further includes a touch wiring 315, at least a portion of the touch wiring 315 is located in the non-display area NA, and one end of the touch wiring 315 is connected to the touch electrode 311 and the other end is connected to the integrated circuit.

[0032] In these optional embodiments, at least a part of the touch wiring 315 is located in the non-display area NA, thereby reducing the luminous influence of the touch wiring 315 on the display area AA1 and ensuring the luminous effect of the display area AA1. One end of the touch wiring 315 is connected to the integrated circuit and the other end is connected to the touch electrode 311, and the integrated circuit provides a touch signal to the touch electrode 311 to realize the touch function of the touch electrode 311.

[0033] In some alternative embodiments, the shield signal wiring 316 and the touch wiring 315 are distributed on both sides of the display area AA1.

[0034] In these alternative embodiments, the shield signal wiring 316 and the touch wiring 315 are separately arranged in the non-display areas NA on both sides of the display area AA1, and both the shield signal wiring 316 and the touch wiring 315 have a large wiring space, which makes it easy to wire the shield signal wiring 316 and the touch wiring 315, and both the shield signal wiring 316 and the touch wiring 315 are located in the non-display area NA on one side of the display area AA1, which solves the problem of the shield signal wiring 316 and the touch wiring 315 colliding with each other and short-circuiting. In addition, the signals of the shield signal wiring 316 and the touch wiring 315 are less likely to affect each other, and the stability of the signals of the shield signal wiring 316 and the touch wiring 315 is ensured.

[0036] In some optional embodiments, as shown in FIG. 4, the first connection portion 321 connects multiple first dummy electrodes 313 in the same light-transmitting area AA2, and / or as shown in FIG. 5, the first connection portion 321 connects first dummy electrodes 313 located in multiple different light-transmitting areas AA2.

[0037] In these optional embodiments, each first dummy electrode 313 is electrically connected to form a whole, and after multiple first dummy electrodes 313 are connected to each other, the entire first dummy electrodes 313 can be grounded with only a single wiring, reducing the number of wirings and simplifying the manufacturing process.

[0038] In some alternative embodiments, one or more first dummy electrodes 313 are located in the same light-transmitting area AA2.

[0039] In these alternative embodiments, the electrode located in the light-transmitting region AA2 in the touch layer 300 is the first dummy electrode 313. The light-transmitting region AA2 may be larger than the first dummy electrode 313, i.e., the first dummy electrode 313 may be located completely within the light-transmitting region AA2. The light-transmitting region AA2 may be smaller than the first dummy electrode 313, i.e., the first dummy electrode 313 may be located partially within the light-transmitting region AA2.

[0043] Optionally, the multiple first dummy electrodes 313 distributed along the first direction X are located in the same column and connect the first dummy electrodes 313 in the same column in the first direction X, that is, the first connection portion 321 extends in the first direction X to reduce collision with other wirings of the second conductive layer 320 extending in the first direction X.

[0044] Optionally, at least one second dummy electrode 314 is located in the same column as the first dummy electrode 313 in the first direction X, and when the first dummy electrode 313 is electrically connected to a shield signal via the second dummy electrode 314, the first dummy electrode 313 and the second dummy electrode 314 are located in the same column, and a first connection portion 321 connecting the first dummy electrode 313 and the second dummy electrode 314 extends in the first direction X to reduce collision with other wirings of the second conductive layer 320 extending in the first direction X.

[0046] As shown in FIGS. 8 and 9 , 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 portion 322 extending along a first direction X, the multiple touch sensing electrodes 319 distributed along the first direction X are bridge-connected by the second connection portion 322, and the multiple touch driving electrodes 318 distributed along the second direction Y are electrically connected to each other in the first conductive layer 310, and the first direction X and the second direction Y cross each other.

[0047] In these optional embodiments, the touch driving electrodes 318 and the touch sensing electrodes 319 are distributed along a first direction X and a second direction Y to form a mutual capacitance touch display panel 10.

[0048] In some optional embodiments, the first conductive layer 310 includes a third connection portion extending along the second direction Y, and the multiple touch drive electrodes 318 distributed along the second direction Y are electrically connected to each other by the third connection portion, and a positive projection of the first connection portion 321 on the substrate 100 overlaps with a positive projection of the third connection portion on the substrate 100.

[0049] In these optional embodiments, the first connection portion 321 has one end connected to the first dummy electrode 313 and is connected to the first dummy electrode 313 located on the other side of the touch drive electrode 318 across the touch drive electrode 318.

[0050] Optionally, the touch electrode 311 is arranged to surround the dummy electrode 312, and the touch electrode 311 is installed between adjacent dummy electrodes 312, and the dummy electrodes 312 are bridge-connected by first connection parts 321 of different layers to realize that the first connection parts 321 and the touch electrode 311 do not collide with each other.

[0051] Alternatively, the first dummy electrode 313 is located within the touch sensing electrode 319, i.e., the touch sensing electrode 319 is arranged to surround the first dummy electrode 313, the first dummy electrode 313 and the touch sensing electrode 319 have the same distribution direction, and the first connection portion 321 and the second connection portion 322 have the same extension direction, so that the first connection portion 321 and the second connection portion 322 do not collide with each other, and the reliability of the first connection portion 321 and the second connection portion 322 is improved.

[0052] In some alternative embodiments, the orthogonal projections of the touch electrodes 311 and the dummy electrodes 312 on the substrate 100 are located outside the orthogonal projections of the light-transmitting aperture 250 on the substrate 100 .

[0053] In these optional embodiments, the touch electrode 311 and the dummy electrode 312 are both positioned out of alignment with the light-transmitting opening 250 to prevent the touch electrode 311 and the dummy electrode 312 from blocking the light-transmitting opening 250, and ensure the transmittance of the light-transmitting opening 250.

[0054] Optionally, at least a portion of the touch electrodes 311 and the dummy electrodes 312 are positioned within the orthogonal projection of the isolation structure 200 on the substrate 100, thereby reducing the shielding of the touch electrodes 311 and the dummy electrodes 312 to the light-transmitting opening 250 and other light-transmitting portions (e.g., the pixel limiting portion 610) and improving the overall transmittance of the display panel 10.

[0055] In some alternative embodiments, the dummy electrodes 312 include third dummy electrodes 317 located in the display area AA1, and each of the third dummy electrodes 317 is arranged in a floating manner.

[0056] The third dummy electrode 317 being arranged to be raised means that the third dummy electrode 317 is not connected to any of the other dummy electrodes 312, the touch electrode 311, and the wiring, and has a structure in which it does not conduct electricity independently.

[0057] In these alternative embodiments, when the third dummy electrode 317 is provided, a dummy electrode 312 is provided at each position of the display panel 10 to improve the touch and display uniformity.

[0058] Please refer to FIG. 10, which is a partial cross-sectional view of a display panel according to still another embodiment.

[0059] As shown in FIG. 10 , in some optional embodiments, the display panel 10 further includes an emitting layer 400 and a first electrode layer 500, where the emitting layer 400 is located on one side of the substrate 100, the emitting layer 400 includes a emitting unit 410 located in the isolation opening 240, and the first electrode layer 500 is located on the side of the emitting layer 400 away from the substrate 100.

[0060] Optionally, the first electrode layer 500 includes a first electrode 510 located in the isolation opening 240 , where the first electrode 510 is electrically connected to the isolation structure 200 .

[0061] In these optional embodiments, the isolation structure 200 interrupts the first electrode layer 500 to form the first electrodes 510 spaced apart from each other, and the first electrodes 510 spaced apart from each other are electrically connected via the isolation structure 200 to form a full-surface electrode, thereby ensuring normal emission of the light-emitting unit 410.

[0062] In some alternative embodiments, the orthogonal projection of each light-emitting unit 410 on the substrate 100 is located within the orthogonal projection of each first electrode 510 on the substrate 100 .

[0063] In these optional embodiments, the orthogonal projection of the light-emitting unit 410 on the substrate 100 is located within the orthogonal projection of the first electrode 510 on the substrate 100, i.e., the first electrode 510 is installed covering the light-emitting unit 410 as an electrode of the light-emitting unit 410, so as to ensure normal emission of the light-emitting unit 410 and improve the display effect of the display panel 10.

[0064] Optionally, the light-emitting units 410 and the isolation structure 200 are spaced apart, i.e., the light-emitting units 410 are spaced apart from each other to reduce carrier crosstalk between the light-emitting units 410 and improve the crosstalk problem of the light-emitting units 410.

[0065] In some optional embodiments, the isolation structure 200 includes a first layer 210 and a second layer 220 located on a side of the first layer 210 away from the substrate 100, and an orthogonal projection of the first layer 210 on the substrate 100 is located within an orthogonal projection of the second layer 220 on the substrate 100.

[0066] In these alternative embodiments, the first layer 210 and the second layer 220 are provided to form the isolation structure 200, and the orthogonal projection of the first layer 210 disposed adjacent to the substrate 100 is located within the orthogonal 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, and at this time, the first layer 210 is recessed relative to the second layer 220 in a direction away from the isolation opening 240. When the light-emitting layer 400 is manufactured, the light-emitting layer 400 generates a relatively large step at the edge of the isolation structure 200, and the first layer 210 is recessed relative to the second layer 220, so that the light-emitting layer 400 is difficult to connect at the edge of the isolation structure 200, and thus a break occurs, and the light-emitting layer 400 is broken to form the light-emitting units 410 that are disconnected from each other.

[0067] In some alternative embodiments, the second layer 220 comprises a conductive material or an insulating material.

[0068] 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. If the second layer 220 is a non-metallic conductive material or an insulating material, the second layer 220 is less likely to be etched during the process of wet etching the first layer 210 using an etching solution, and the first layer 210 is more likely to be recessed relative to the second layer 220.

[0069] 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.

[0070] In these alternative embodiments, when the first layer 210 and the second layer 220 are both made of metal materials, the first layer 210 can be wet-etched using an etching solution, and the etching rate of the second layer 220 can be made smaller than the etching rate of the first layer 210 by exposure to the etching solution. When the etching rate of the first layer 210 is large and wet etching is performed using an etching solution, even if the second layer 220 is subjected to a certain amount of etching, the first layer 210 is etched faster than the first layer 210, so that the first layer 210 is recessed relative to the second layer 220.

[0071] In some optional embodiments, the isolation structure 200 further includes a third layer 230 located on the side of the first layer 210 facing the substrate 100, and an orthogonal projection of the first layer 210 on the substrate 100 is located within an orthogonal projection of the third layer 230 on the substrate 100.

[0072] In these alternative embodiments, in the process of etching to obtain the recessed first layer 210, the first layer 210 has a faster etching rate than the second layer 220 and the third layer 230, thereby forming the recessed first layer 210. Because the etching rate of the first layer 210 is fast, waste generated by etching is likely to enter other positions of the display panel 10, which may cause adverse effects. When the third layer 230 is provided, the first layer 210 can adhere well on the third layer 230, and the generated etching waste falls onto the third layer 230, making it easy to clean.

[0073] In some optional embodiments, the display panel 10 further includes a pixel definition layer 600, which is located on the substrate 100, and which includes a pixel limiting portion 610 and a pixel opening 620 surrounded by the pixel limiting portion 610, and the light-emitting unit 410 is located in the pixel opening 620, and the pixel opening 620 is in communication with the isolation opening 240.

[0074] In these optional embodiments, the pixel opening 620 surrounded by the pixel limiting portion 610 is used to install the light emitting unit 410 to realize the light emitting display of the display panel 10. The pixel opening 620 is installed in communication with the isolation opening 240, which reduces the shielding of the isolation structure 200 against the pixel opening 620 and ensures the light emitting effect of the light emitting unit 410.

[0075] Optionally, the display panel 10 further includes a pixel electrode 640 exposed from the pixel opening 620, where one of the pixel electrode 640 and the first electrode 510 functions as an anode of the light-emitting unit 410, and the other functions as a cathode of the light-emitting unit 410. In the embodiment of the present application, the pixel electrode 640 is exemplified as the anode of the light-emitting unit 410, and the first electrode 510 is exemplified as the cathode of the light-emitting unit 410.

[0076] In some alternative embodiments, the isolation structure 200 is located on the side of the pixel limiting portion 610 away from the substrate 100 .

[0077] In these alternative embodiments, the isolation structure 200 is disposed in the pixel limiting portion 610, and the isolation structure 200 corresponds to the pixel opening 620 and has a large step. Due to the large step, when manufacturing the light emitting layer 400, the light emitting layer 400 is more likely to be divided at the position of the isolation structure 200, and the manufacturing difficulty of the light emitting layer 400 is reduced.

[0078] In some alternative embodiments, the pixel limiting portion 610 has a receiving opening 630 , and the isolation structure 200 is located in the receiving opening 630 .

[0079] In these optional embodiments, the isolation structure 200 is disposed in the receiving opening 630 in the pixel limiting portion 610, and during the manufacturing process, the manufacturing step of the isolation structure 200 is performed prior to the manufacturing of the pixel electrode 640, i.e., after manufacturing the isolation structure 200 on the substrate 100, the pixel electrode 640 is manufactured on the substrate 100, so as to reduce the impact of the manufacturing of the isolation structure 200 on the pixel electrode 640 and ensure that the pixel electrode 640 is not damaged.

[0080] Optionally, the orthogonal projection of the touch electrode 311 and the dummy electrode 312 on the substrate 100 is located outside the orthogonal projection of the pixel opening 620 on the substrate 100, and the touch electrode 311 and the dummy electrode 312 are both misaligned with the pixel opening 620 to avoid the touch electrode 311 and the dummy electrode 312 blocking the pixel opening 620 and ensure the normal emission of the light-emitting unit 410.

[0081] In some optional embodiments, the display panel 10 further includes an encapsulation layer 700 located between the first electrode layer 500 and the touch layer 300 .

[0082] In these optional embodiments, the sealing layer 700 is provided on the side of the first electrode layer 500 away from the substrate 100, thereby sealing the first electrode 510 and the light-emitting layer 400 to reduce the ingress of water and oxygen and extend the service life of the display panel 10.

[0083] Optionally, the light-emitting layer 400 includes an electron injection layer (EIL), an electron transport layer (ETL), a layer of light-emitting material, a hole injection layer (HIL), and a hole transport layer (HTL).

[0084] An embodiment of the second aspect of the present application provides a display panel 10, which has a display area AA1 and a light-transmitting area AA2, and further includes a substrate 100, an isolation structure 200, and a touch layer 300, in which the isolation structure 200 is located on one side of the substrate 100, and the isolation structure 200 is surrounded to form 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 arrange the light-emitting unit 410, the light-transmitting opening 250 is located in the light-transmitting area AA2, and the touch layer 300 is an isolation structure. Located on the side of the structure 200 away from the substrate 100, the touch layer 300 includes a first conductive layer 310 and a second conductive layer 320 arranged in a stacked manner, the first conductive layer 310 includes a touch electrode 311 and a dummy electrode 312 arranged so as to be spaced apart and insulated from each other, the number of dummy electrodes 312 is multiple, at least one dummy electrode 312 of the multiple dummy electrodes 312 overlaps the light-transmitting region AA2, the second conductive layer 320 includes a first connection portion 321, and the multiple dummy electrodes 312 are bridge-connected via the first connection portion 321.

[0085] 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 disposed on the substrate 100 and surrounds it to form a plurality of isolation openings 240, which are used to block the light-emitting layer 400 to form the light-emitting units 410 separated from each other, thereby reducing the crosstalk of carriers in the light-emitting layer 400, improving the display effect of the display panel 10, and eliminating the need to use precision masks to manufacture the light-emitting units 410, reducing the development and use of precision masks, and reducing manufacturing costs. The isolation structure 200 has a light-transmitting opening 250, 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 dummy electrode 312 that are spaced apart and insulated from each other, the touch electrode 311 is used to realize the touch function of the display panel 10, and the dummy electrode 312 and the touch electrode 311 are spaced apart and insulated from each other, that is, signals between the dummy electrode 312 and the touch electrode 311 are independent from each other. At least a part of the dummy electrode 312 is located in the light-transmitting region AA2, and signals of the substrate 100 interfere with the dummy electrode 312 through the light-transmitting opening 250, but the touch electrode 311 and the dummy electrode 312 are insulated from each other, so that the interference of the touch electrode 311 is small, and the touch performance of the touch electrode 311 is improved. Each dummy electrode 312 is electrically connected to form a whole by a first connection portion 321, and after multiple first dummy electrodes 313 are connected to each other, all of the first dummy electrodes 313 can be grounded with only one wiring, reducing the number of wirings and simplifying the manufacturing process.
