[0103] In these alternative embodiments, the first electrode layer 500 and the second electrode layer 200 can serve as a pixel electrode layer of the display panel 10. One of the first electrodes 510 and the second electrodes 210 can serve as an anode, and the other can serve as a cathode to drive the light-emitting unit 410 to emit light. The embodiments of the present application take the first electrode 510 as the cathode of the display panel 10 and the second electrode 210 as the anode of the display panel 10 as an example.

[0104] In some embodiments of the present application, the touch electrode 610 can be provided in various forms, wherein the touch electrode 610 of the present application can be a mutual-capacitance-based touch electrode 610 or a self-capacitance-based touch electrode 610. Optionally, the touch electrode 610 and the dummy electrode 620 can comprise a multi-layer structure (not shown in the figure), wherein at least part of the touch electrode 610 can be provided in the same layer as at least part of the dummy electrode 620, so as to facilitate the preparation of the touch electrode 610 and the dummy electrode 620.

[0105] In some optional embodiments, the isolation structure 300 can be in a grid shape, and the hollowed-out areas in the grid-shaped isolation structure 300 can be the isolation openings 300b and the light-transmitting openings 300a.

[0106] As shown in Figures 1 to 3 In some optional embodiments, the light transmittance of the second area AA2 is greater than that of the first area AA1.

[0107] Optionally, the number of the light-transmitting openings 300a is one or more than two, and at least two light-transmitting openings 300a are provided at intervals.

[0108] The second area AA2 can correspond to a sensor, which can include at least one of an ambient light sensor, a camera, a fingerprint sensor, etc. The second area AA2 can have a display function or not have a display function, which is not specifically limited here.

[0109] The light-transmitting opening 300a provided in the isolation structure 300 in the second area AA2 can better allow the light to pass through, so as to improve the light transmittance of the display panel 10, so that when the display panel 10 is applied to a display device, the photosensitive component for sensing light in the display device can be correspondingly provided below the light-transmitting opening 300a, so that the photosensitive component can better sense light through the light-transmitting opening 300a.

[0110] Optionally, the light-transmitting opening 300a can not be provided with the first electrode 510, the light-emitting unit 410, and the second electrode 210, so that the display panel 10 can have better light transmittance at the light-transmitting opening 300a.

[0111] Optionally, the light-transmitting opening 300a can be provided only in the second region AA2, that is, the first region AA1 may not have a light-transmitting opening 300a. This allows the second region AA2 in the display panel 10 to have good light transmittance, and allows the first region AA1 in the display panel 10 to have sufficient area to provide isolation openings 300b. This results in a larger number of isolation openings 300b in the first region AA1, enabling the first region AA1 to have denser sub-pixels, which can effectively improve the pixel density (Pixels Per Inch, PPI) of the first region AA1, thereby improving the display effect of the display panel 10. Furthermore, since the first region AA1 does not have a light-transmitting opening 300a, the signals in the array substrate 100 are less likely to interfere with the touch signals in the first region AA1, thus improving the operational reliability of the display panel 10.

[0112] Optionally, the isolation opening 300b may also be located in the second region AA2, that is, the isolation opening 300b may be located in the first region AA1 and the second region AA2.

[0113] Optionally, each of the isolation openings 300b in the first region AA1 and the second region AA2 has a light-emitting unit 410. For example, each of the isolation openings 300b in the first region AA1 and the second region AA2 is provided with a first electrode 510, a light-emitting unit 410 and a second electrode 210, so that each of the first region AA1 and the second region AA2 has a sub-pixel that can emit light, thereby improving the screen ratio of the display panel 10.

[0114] The size and arrangement of each isolation opening 300b can be set in various ways. Optionally, the size and arrangement of each isolation opening 300b can be set according to the light emission color of the light-emitting unit 410 within the isolation opening 300b. Optionally, the size and arrangement of each isolation opening 300b can also be set according to the pixel density requirements of the display panel 10.

[0115] like Figure 2 and Figure 3 As shown, in some optional embodiments, within the second region AA2, the light-transmitting opening 300a may be located between two adjacent isolation openings 300b.

[0116] Optionally, at least two light-transmitting openings 300a are spaced apart in the first direction Y, and / or at least two light-transmitting openings 300a are spaced apart in the second direction Z.

[0117] By reasonably setting the arrangement of the light-transmitting openings 300a, the light-transmitting openings 300a without related light-emitting devices are not easily arranged in a concentrated manner, which can better improve the display uniformity of the display panel 10.

[0118] In some optional embodiments, the touch electrodes 610 can be connected with the touch signal lines of the display panel 10 to receive touch signals, so that the touch electrodes 610 in the touch area 600a can participate in the touch sensing work of the display panel 10.

[0119] Optionally, the touch area 600a can be arranged in the first area AA1, so that the display panel 10 in the first area AA1 can have the touch sensing function through the touch electrodes 610 in the touch area 600a, and the touch electrodes 610 in the touch area 600a are less likely to be interfered by the signals in the array substrate 100 leaking out through the light-transmitting opening 300a in the second area AA2.

[0120] In some optional embodiments, the dummy electrodes 620 can not be connected with the touch signal lines, i.e., the dummy electrodes 620 in the non-touch area 600b do not participate in the touch sensing work of the display panel 10.

[0121] Optionally, the size of the dummy electrodes 620 in the thickness direction X of the display panel 10 can be equal to the size of the touch electrodes 610 in the thickness direction X of the display panel 10.

[0122] By arranging the dummy electrodes 620 in the non-touch area 600b, the touch layer 600 in the touch area 600a and the touch layer 600 in the non-touch area 600b can have similar film thicknesses, so that the display panel 10 can have better flatness, and the touch area 600a and the non-touch area 600b are less likely to have large reflectivity or visual color difference, so that the display panel 10 can have better optical quality and display uniformity. In addition, the dummy electrodes 620 arranged in the non-touch area 600b can also shield and block the crosstalk between the touch signals and the signals in the array substrate 100, so as to improve the light-emitting stability and touch stability of the display panel 10.

[0123] Optionally, at least part of the non-touch area 600b can be arranged in the second area AA2. Optionally, the inner wall of the isolation structure 300 surrounding the light-transmitting opening 300a is orthogonally projected on the touch layer 600 in the non-touch area 600b.

[0124] In these optional embodiments, the position relationship between the second area AA2 and the non-touch area 600b can be reasonably set, or the position relationship between the light-transmitting opening 300a and the non-touch area 600b can be reasonably set, so that the non-touch area 600b can be better covered above the second area AA2 or the light-transmitting opening 300a, so that the virtual electrode 620 can shield and shield the signal in the array substrate 100 that is easily leaked through the light-transmitting opening 300a in the second area AA2, so that the signal in the array substrate 100 that is leaked through the light-transmitting opening 300a in the second area AA2 is not easy to cause crosstalk with the touch signal in the touch electrode 610 in the display area.

[0125] In some embodiments, the second area AA2 of the display panel 10 can be used to allow better light transmission so that the light can be sensed by the photosensitive component. Optionally, the second area AA2 can be used to allow better light transmission so that the sensor can be sensed, for example, the infrared light emitting diode (IR-LED) proximity sensor on one side of the display panel 10 can be facilitated.

[0126] Optionally, the number of the second areas AA2 in the display panel 10 can also be multiple, so that when the number of the photosensitive components in the display device is at least two, each photosensitive component can be arranged under a different second area AA2 or non-touch area 600b, so that the photosensitive components under different second areas AA2 can better sense the light through the light-transmitting opening 300a, and the signal in the array substrate 100 is not easy to cause crosstalk with the touch signal at the virtual electrode 620 in the non-touch area 600b.

[0127] For example, at least part of the second area AA2 can also be used to allow better light transmission so as to facilitate the sensing of the under-screen fingerprint recognition module on one side of the display panel 10.

[0128] Optionally, the touch area 600a is arranged around at least part of the non-touch area 600b, so that the touch area 600a and the non-touch area 600b have a better arrangement position relationship, so that the touch layer 600 of the display panel 10 can have a larger area of the touch area 600a to participate in the touch work.

[0129] In some optional embodiments, the orthographic projection of the virtual electrode 620 on the array substrate 100 is located within the orthographic projection of the isolation structure 300 on the array substrate 100, so that the virtual electrode 620 is not easy to block the isolation opening 300b and the light-transmitting opening 300a formed on the isolation structure 300 in the thickness direction X of the display panel 10, so that the setting of the virtual electrode 620 is not easy to block the light-emitting display of the display panel 10, and also makes the virtual electrode 620 not easy to affect the light transmittance of the display panel 10 at the light-transmitting opening 300a.

[0130] In some optional embodiments, the orthogonal projection of the touch electrode 610 on the array substrate 100 is located within the orthogonal projection of the isolation structure 300 on the array substrate 100, so that the touch electrode 610 is less likely to shield the isolation opening 300b formed in the isolation structure 300 in the thickness direction X of the display panel 10, thereby making the arrangement of the touch electrode 610 less likely to shield the light-emitting display of the display panel 10.

[0131] In some optional embodiments, the orthogonal projection of the dummy electrode 620 on the isolation structure 300 is arranged around at least part of the isolation opening 300b, and / or the orthogonal projection of the dummy electrode 620 on the isolation structure 300 is arranged around at least part of the light-transmitting opening 300a, so that the dummy electrode 620 can have a better wiring area while being less likely to shield the light-emitting display of the display panel 10 and less likely to affect the light transmittance of the display panel 10 at the light-transmitting opening 300a, thereby being able to improve the shielding and shielding effect of the dummy electrode 620 on the crosstalk between the touch signal and the signal in the array substrate 100.

[0132] Optionally, the dummy electrode 620 is in a grid shape, wherein the hollow regions in the grid-shaped dummy electrode 620 can be arranged corresponding to the light-transmitting openings 300a and the isolation openings 300b, i.e., the hollow regions in the grid-shaped dummy electrode 620 can be located on the side of the light-transmitting openings 300a and the isolation openings 300b away from the array substrate 100 in the thickness direction X of the display panel 10.

[0133] Optionally, the orthogonal projection of the touch electrode 610 on the isolation structure 300 is arranged around at least part of the isolation opening 300b, so that the touch electrode 610 can have a better wiring area while being less likely to shield the light-emitting display of the display panel 10, thereby being able to improve the touch sensing capability of the display panel 10.

[0134] Optionally, the touch electrode 610 is in a grid shape, wherein the hollow regions in the grid-shaped touch electrode 610 can be arranged corresponding to the isolation openings 300b, i.e., the hollow regions in the grid-shaped touch electrode 610 can be located on the side of the isolation openings 300b away from the array substrate 100 in the thickness direction X of the display panel 10.

[0135] Optionally, when the orthographic projection of the virtual electrode 620 on the isolation structure 300 surrounds at least part of the isolation opening 300b, and the orthographic projection of the touch electrode 610 on the isolation structure 300 surrounds at least part of the isolation opening 300b, the extension shape of the touch electrode 610 can be similar to the extension shape of the virtual electrode 620. For example, both the virtual electrode 620 and the touch electrode 610 can be in a grid shape, so that there is less likely to be excessive reflectivity or visual color shift difference between the touch area 600a and the non-touch area 600b, and the display panel 10 can have better optical image quality and display uniformity.

[0136] Optionally, the width of the virtual electrode 620 and / or the touch electrode 610 may be less than or equal to the width of the isolation structure 300. Optionally, the width of the virtual electrode 620 may refer to the distance between the two surfaces of the virtual electrode 620 facing the isolation opening 300b, or the width of the virtual electrode 620 may refer to the distance between the two surfaces of the virtual electrode 620 facing the light-transmitting opening 300a. Optionally, the width of the touch electrode 610 may refer to the distance between the two surfaces of the touch electrode 610 facing the isolation opening 300b. Optionally, the width of the isolation structure 300 may refer to the distance between the two surfaces of the isolation structure 300 facing the isolation opening 300b, or the width of the isolation structure 300 may refer to the distance between the two surfaces of the isolation structure 300 facing the light-transmitting opening 300a.

[0137] Optionally, the width of the touch electrode 610 can be equal to the maximum width of the isolation structure 300, so that the touch electrode 610 can have a better width to transmit touch signals, thereby increasing the touch sensing capability of the display panel 10.

[0138] Optionally, the distance between the orthographic projection of the virtual electrode 620 on the isolation structure 300 and the light-transmitting opening 300a is greater than or equal to 1.5 μm, and / or the minimum spacing between the orthographic projection of the virtual electrode 620 on the isolation structure 300 and the isolation opening 300b is greater than or equal to 1.5 μm, for example, as... Figure 3 As shown, the distance between the orthographic projection of the virtual electrode 620 on the isolation structure 300 and the light-transmitting opening 300a can be a first spacing L1, and the minimum spacing between the orthographic projection of the virtual electrode 620 on the isolation structure 300 and the isolation opening 300b can be a second spacing L2. Both the first spacing L1 and the second spacing L2 can be greater than or equal to 1.5μm. This can improve the problem of easily blocking the light-transmitting opening 300a and / or the isolation opening 300b when the virtual electrode 620 manufacturing process fluctuates, helping to ensure product yield and thus improving the display effect and light transmittance of the second region AA2.

[0139] like Figure 2 and Figure 3As shown, in some embodiments of the present application, there are multiple methods for insulating the touch electrode 610 from the dummy electrode 620.

[0140] In some alternative embodiments, the touch layer 600 can include an insulating portion 630 disposed between the touch electrode 610 and the dummy electrode 620. Optionally, the material of the insulating portion 630 can include an insulating material. By disposing the insulating portion 630 between the touch electrode 610 and the dummy electrode 620, the touch electrode 610 and the dummy electrode 620 can be insulated from each other by the insulating portion 630, so that the touch signal in the touch electrode 610 is less likely to interfere with the signal in the array substrate 100 through the dummy electrode 620.

[0141] Optionally, the insulating portion 630 can be disposed around at least part of the non-touch area 600b, for example, the insulating portion 630 can be disposed between the touch area 600a and the non-touch area 600b.

[0142] Optionally, the orthographic projection of the insulating portion 630 on the array substrate 100 can be located within the orthographic projection of the isolation structure 300 on the array substrate 100, so that the insulating portion 630 can be disconnected from the side of the isolation opening 300b away from the substrate, so that the insulating portion 630 is less likely to block the isolation opening 300b formed on the isolation structure 300 in the thickness direction X of the display panel 10, thereby making the insulating portion 630 less likely to block the light-emitting display of the display panel 10.

[0143] Optionally, the size of the insulating portion 630 in the thickness direction X of the display panel 10 can be equal to the size of the touch electrode 610 in the thickness direction X of the display panel 10, and / or the size of the insulating portion 630 in the thickness direction X of the display panel 10 can be equal to the size of the dummy electrode 620 in the thickness direction X of the display panel 10, so that the touch layer 600 can have a relatively uniform thickness, and so that the display panel 10 can have a better flatness.

[0144] Figure 4 is a partial enlarged schematic view of the touch layer 600 and the isolation structure 300 provided by another embodiment of the present application.

[0145] As shown, in some embodiments of the present application, there are multiple methods for insulating the touch electrode 610 from the dummy electrode 620. Figure 4 As shown, in some embodiments of the present application, there are multiple methods for insulating the touch electrode 610 from the dummy electrode 620.

[0146] By providing an isolation groove 640 between the touch electrode 610 and the virtual electrode 620, the touch electrode 610 and the virtual electrode 620 can be insulated from each other through the isolation groove 640, thereby making it less likely for the touch signal in the touch electrode 610 to crosstalk with the signal in the array substrate 100 through the virtual electrode 620.

[0147] Optionally, the partition groove 640 is provided around at least a portion of the non-touch area 600b, for example, the partition groove 640 may be provided between the touch area 600a and the non-touch area 600b.

[0148] Figure 5 This is a partially enlarged schematic diagram of a touch layer 600 and an isolation structure 300 provided in another embodiment of this application.

[0149] like Figure 5 As shown, in some optional embodiments, the number of virtual electrodes 620 may be at least two, with adjacent virtual electrodes 620 spaced apart. By setting the number of virtual electrodes 620 to multiple and arranging them spaced apart, the arrangement of the virtual electrodes 620 can be facilitated.

[0150] Figure 6 This is a partial schematic diagram of an isolation structure 300 and a virtual electrode 620 provided in an embodiment of this application. Figure 7 This is a partially enlarged schematic diagram of an isolation structure 300 and a virtual electrode 620 provided in an embodiment of this application.

[0151] like Figure 6 and Figure 7 As shown, in some optional embodiments, a plurality of isolation openings 300b are spaced apart along a first preset direction J and a second preset direction K. A portion of the virtual electrodes 620 are located between adjacent isolation openings 300b along the first preset direction J, and another portion of the virtual electrodes 620 are located between adjacent isolation openings 300b along the second preset direction K. The first preset direction J intersects with the second preset direction K. Optionally, the first preset direction J may be perpendicular to the second preset direction K.

[0152] For example, the virtual electrode 620 includes a first type of electrode 621 and a second type of electrode 622. The first type of electrode 621 is located between adjacent isolation openings 300b in the first preset direction J, and the second type of electrode 622 is located between adjacent isolation openings 300b in the second preset direction K.

[0153] In the optional embodiment, by reasonably setting the distribution of the isolation openings 300b, the size of the display panel 10 can be better utilized, so as to better improve the arrangement compactness of the isolation openings 300b and the light emitting units 410 in the isolation openings 300b. Meanwhile, by arranging the virtual electrodes 620 along the arrangement direction of the isolation openings 300b and setting the virtual electrodes 620 between the adjacent isolation openings 300b, the size of the isolation structure 300 between the adjacent isolation openings 300b in the first preset direction J and the second preset direction K can be better utilized to arrange the virtual electrodes 620, so as to improve the arrangement compactness of the isolation openings 300b and the virtual electrodes 620.

[0154] Optionally, the first-type electrodes 621 can be formed in extension along the second preset direction K, and / or the second-type electrodes 622 can be formed in extension along the first preset direction J. By reasonably setting the extension directions of the first-type electrodes 621 and the second-type electrodes 622, the size of the isolation structure 300 between the adjacent isolation openings 300b in the first preset direction J and the second preset direction K can be better utilized to arrange the virtual electrodes 620.

[0155] In some optional embodiments, the first-type electrodes 621 are distributed at intervals in the second preset direction K, and / or the second-type electrodes 622 are distributed at intervals in the first preset direction J.

[0156] Optionally, the light-transmitting openings 300a can be located between two first-type electrodes 621 adjacent in the second preset direction K and between two second-type electrodes 622 adjacent in the first preset direction J.

[0157] In these optional embodiments, by setting the first type of electrodes 621 to be spaced apart in the second preset direction K and the second type of electrodes 622 to be spaced apart in the first preset direction J, a certain gap space can be provided between the first type of electrodes 621 and between the second type of electrodes 622 to facilitate the arrangement of the light-transmitting opening 300a. By setting the light-transmitting opening 300a between two adjacent first type of electrodes 621 in the second preset direction K and two adjacent second type of electrodes 622 in the first preset direction J, multiple isolation openings 300b can better surround the periphery of the light-transmitting opening 300a, and the light-transmitting opening 300a can also be set above the larger-sized partial isolation structure 300 between the multiple isolation openings 300b, so as to arrange a larger-sized light-transmitting opening 300a, thereby improving the compactness of the arrangement of the isolation openings 300b, the light-transmitting opening 300a, and the virtual electrode 620. Furthermore, this design ensures that the virtual electrode 620 and the light-transmitting opening 300a are not simultaneously provided on the partial isolation structure 300 between two adjacent isolation openings 300b. This improves the problem that the light-transmitting opening 300a and / or isolation opening 300b are easily blocked when the virtual electrode 620 manufacturing process fluctuates. It also allows for a smaller gap between two adjacent isolation openings 300b to facilitate the setting of larger or more isolation openings 300b, thereby improving the display effect of the display panel 10.

[0158] In some embodiments of this application, the first direction Y and the second direction Z may be the main extension directions of the display panel 10 as a whole, and the user can mainly view the light-emitting display content of the display panel 10 in the first direction Y and the second direction Z.

[0159] Optionally, there are multiple relative positional relationships between the first direction Y, the second direction Z, the first preset direction J, and the second preset direction K. The specific relative positions of the first direction Y, the second direction Z, the first preset direction J, and the second preset direction K can be set according to the specific shape of the isolation opening 300b.

[0160] Optionally, the shape of the isolation opening 300b can be set in various ways. For example, the shape of the orthographic projection of the inner wall of the isolation structure 300 surrounding the isolation opening 300b onto the array substrate 100 can be a polygon, a circle, an ellipse, a combination of multiple shapes, or an irregular shape.

[0161] like Figure 6 and Figure 7 As shown, in some embodiments, the first preset direction J can be parallel to the first direction Y, and the second preset direction K can be parallel to the second direction Z, so that the isolation openings 300b can be distributed at intervals along the length and width directions of the display panel.

[0162] Figure 8is a partial schematic view of an isolation structure 300 and a virtual electrode 620 provided by an embodiment of the present application.

[0163] As shown in FIG. 1, in some embodiments, the first preset direction J can be parallel to the first direction Y, and the second preset direction K can be parallel to the second direction Z. Figure 8 As shown in FIG. 2, in some other embodiments, the first preset direction J can intersect the first direction Y, and the second preset direction K can intersect the second direction Z, so as to arrange the isolation openings 300b according to the shape of the isolation openings 300b.

[0164] Optionally, the included angle between the first preset direction J and the first direction Y can range from 30° to 60°, and the included angle between the second preset direction K and the second direction Z can also range from 30° to 60°, so that the arrangement of the isolation openings 300b can also be relatively uniform in the first direction Y and the second direction Z, and the color cast of the display panel in the first direction Y and the second direction Z can not be easily affected.

[0165] Optionally, the included angle between the first preset direction J and the first direction Y can be 45°, and the included angle between the second preset direction K and the second direction Z can also be 45°. In addition, the included angle between the first preset direction J and the first direction Y can be 40° or 50°, and the included angle between the second preset direction K and the second direction Z can also be 40° or 50°, which is not limited herein.

[0166] In some optional embodiments, the at least two virtual electrodes 620 are symmetrically arranged about a first symmetry axis S1, and / or the at least two virtual electrodes 620 are arranged about a second symmetry axis S2, wherein the first symmetry axis S1 extends along the first direction Y and passes through the geometric center of the isolation opening 300b, and the second symmetry axis S2 extends along the second direction Z and passes through the geometric center of the isolation opening 300b.

[0167] As shown in FIG. 3, in some embodiments, the first preset direction J can be parallel to the first direction Y, and the second preset direction K can be parallel to the second direction Z. Figure 6 and Figure 7 As shown in FIG. 4, in some other embodiments, the first preset direction J can intersect the first direction Y, and the second preset direction K can intersect the second direction Z, so as to arrange the isolation openings 300b according to the shape of the isolation openings 300b.

[0168] Figure 9 is a partial enlarged schematic view of an isolation structure 300 and a virtual electrode 620 provided by another embodiment of the present application. Figure 10 is a partial enlarged schematic view of an isolation structure 300 and a virtual electrode 620 provided by still another embodiment of the present application.

[0169] As shown in FIG. 5, in some embodiments, the first preset direction J can be parallel to the first direction Y, and the second preset direction K can be parallel to the second direction Z. Figures 8 to 10As shown, optionally, when the first preset direction J intersects with the first direction Y and the second preset direction K intersects with the second direction Z, the first type of electrodes 621 at least partially surrounding the isolation opening 300b can be symmetrically arranged with the second type of electrodes 622 at least partially surrounding the isolation opening 300b about the first symmetry axis S1, and / or the first type of electrodes 621 at least partially surrounding the isolation opening 300b can be symmetrically arranged with the second type of electrodes 622 at least partially surrounding the isolation opening 300b about the second symmetry axis S2.

[0170] By arranging the virtual electrodes 620 symmetrically about the first symmetry axis S1 and the second symmetry axis S2, the virtual electrodes 620 at least partially surrounding the isolation opening 300b can be arranged more uniformly, so that the symmetric virtual electrodes 620 have similar effects on the color deviation of the light emitting units 410 in the isolation opening 300b, thereby better reducing the color deviation in the second area AA2 and improving the display uniformity of the second area AA2.

[0171] As shown in FIGS. 1A and 1B, the display panel 100 can include a plurality of light emitting units 410, and the plurality of light emitting units 410 can be arranged in a plurality of areas AA1, AA2, and AA3. Figure 9 and Figure 10 As shown in some optional embodiments, the light emitting units 410 can include first light emitting units, and the isolation openings 300b can include first type openings 300c containing the first light emitting units, and the first type openings 300c can be symmetrically arranged about the first symmetry axis S1 and / or the second symmetry axis S2.

[0172] The plurality of light-transmitting openings 300a are arranged around the same first type opening 300c. For the plurality of light-transmitting openings 300a arranged around the same first type opening 300c, the connecting line of the geometric center points of the plurality of light-transmitting openings 300a forms a virtual polygon, and the first symmetry axis S1 and / or the second symmetry axis S2 is a diagonal line of the virtual polygon. In Figure 9 and Figure 10 In the embodiments shown in FIGS. 1A and 1B, there are four light-transmitting openings 300a around the same first type opening 300c, and the connecting line of the geometric center points of the four light-transmitting openings 300a forms a virtual quadrilateral, and the first symmetry axis S1 and the second symmetry axis S2 are two diagonal lines of the virtual quadrilateral.

[0173] In the above embodiments, by reasonably arranging the positions of the first type openings 300c and the virtual electrodes 620, the virtual electrodes 620 can be uniformly arranged around the first type openings 300c, so that the virtual electrodes 620 have similar effects on the color deviation of the first light emitting units in the first type openings 300c, thereby better reducing the color deviation in the second area AA2.

[0174] Optionally, the light emitting color of the first light emitting units is red or blue. For example, as shown in FIG. 1A, some of the first type openings 300c can be used to contain first light emitting units emitting red light. Figure 9 For example, as shown in FIG. 1A, some of the first type openings 300c can be used to contain first light emitting units emitting red light. Figure 10As shown, a portion of the first type of opening 300c can be used to accommodate a first light-emitting unit that emits blue light.

[0175] Figure 11 This is a partially enlarged schematic diagram of an isolation structure 300 and a virtual electrode 620 provided in another embodiment of this application.

[0176] like Figure 11 As shown, in some optional embodiments, the light-emitting unit 410 includes a second light-emitting unit, and the isolation opening 300b includes a second type opening 300d that accommodates the second light-emitting unit. The second type opening 300d is symmetrically arranged about a third axis of symmetry S3 and / or a fourth axis of symmetry S4, wherein the third axis of symmetry S3 extends along a first preset direction J and passes through the geometric center of the second type opening 300d, and the fourth axis of symmetry S4 extends along a second preset direction K and passes through the geometric center of the second type opening 300d.

[0177] When the first preset direction J intersects the first direction Y and the second preset direction K intersects the second direction Z, the second type of opening 300d is symmetrically set about the third axis of symmetry S3 and / or the fourth axis of symmetry S4. That is, by reasonably setting the shape of the second type of opening 300d, the arrangement of the second type of opening 300d is facilitated, so that the isolation structure 300 can be better arranged on the first preset direction J and the second preset direction K.

[0178] In some alternative embodiments, at least two virtual electrodes 620 are symmetrically arranged about a third axis of symmetry S3, and / or at least two virtual electrodes 620 are symmetrically arranged about a fourth axis of symmetry S4.

[0179] Optionally, at least two virtual electrodes 620 on the periphery of the second type opening 300d are symmetrically arranged about the third axis of symmetry S3, and / or at least two virtual electrodes 620 on the periphery of the second type opening 300d are symmetrically arranged about the fourth axis of symmetry S4.

[0180] In these optional embodiments, by setting at least two virtual electrodes 620 symmetrically arranged about the third axis of symmetry S3 and at least two virtual electrodes 620 symmetrically arranged about the fourth axis of symmetry S4, the virtual electrodes 620 can be arranged relatively evenly around the periphery of the second type of opening 300d, so that the virtual electrodes 620 have similar effects on the color shift of the second light-emitting unit within the second type of opening 300d, thereby effectively reducing the color shift at the second region AA2.

[0181] Optionally, the second light-emitting unit emits green light, and the second type of opening 300d can be used to accommodate the second light-emitting unit that emits green light.

[0182] In some embodiments of the present application, the crosstalk between the touch signal in the touch electrode 610 and the signal in the array substrate 100 can be further reduced by adjusting the relative position relationship or the relative area relationship between the touch region 600a and the non-touch region 600b. For example, the crosstalk between the touch signal in the touch electrode 610 and the signal in the array substrate 100 can be reduced by adjusting the distance between the touch electrode 610 and the light-transmitting opening 300a.

[0183] Optionally, the minimum distance between the orthographic projection of the inner wall of the isolation structure 300 enclosing the light-transmitting opening 300a on the array substrate 100 and the orthographic projection of the touch electrode 610 on the array substrate 100 is greater than or equal to 50 μm, so that the touch electrode 610 has a sufficient distance from the light-transmitting opening 300a, and the signal in the array substrate 100 is less likely to affect the touch signal in the touch electrode 610 at a far distance through the light-transmitting opening 300a, thereby better reducing the crosstalk between the touch signal in the touch electrode 610 and the signal in the array substrate 100.

[0184] Optionally, the maximum distance between the boundaries of the non-touch region 600b can be less than or equal to 3 mm, for example, the size of the non-touch region 600b in any direction perpendicular to the thickness direction X of the display panel 10 can be less than or equal to 3 mm, so that the virtual electrode 620 does not have an excessively large area to affect the overall touch sensing capability of the display panel 10. Although the virtual electrode 620 in the non-touch region 600b in this range cannot participate in the touch sensing work, the touch report points in the non-touch region 600b can be compensated by reasonably setting the algorithm of the touch control circuit in the display device, so that the display panel 10 still has good touch sensing capability.

[0185] Figure 12 is a partial cross-sectional view of a display panel 10 provided by another embodiment of the present application.

[0186] As shown in Figure 12 In some optional embodiments, the isolation structure 300 can include a pixel defining portion 320, which can be located between adjacent second electrodes 210, so that short-circuit connection between adjacent second electrodes 210 is less likely to occur, thereby improving the light-emitting display reliability of the display panel 10.

[0187] Optionally, the pixel limiting portion 320 can be used to divide the sub-pixels of the display panel 10. For example, the isolation opening 300b may include a pixel opening 320a opened in the pixel limiting portion 320, at least a portion of the second electrode 210 may be exposed from the pixel opening 320a, and at least a portion of the light-emitting unit 410 may be located in the pixel opening 320a, so that at least a portion of the second electrode 210 may be exposed from the pixel opening 320a to contact the light-emitting unit 410, thereby realizing the light-emitting display of the display panel 10.

[0188] like Figure 12 As shown, in some optional embodiments, the isolation structure 300 may include an isolation post 310, which has a first end 310a and a second end 310b opposite each other in the thickness direction X of the display panel 10. The second end 310b is located on the side of the first end 310a away from the array substrate 100, and the orthographic projection of the first end 310a on the array substrate 100 is located within the orthographic projection of the second end 310b on the array substrate 100.

[0189] By setting the orthographic projection of the first end 310a of the isolation pillar 310 on the array substrate 100 to be within the orthographic projection of the second end 310b of the isolation pillar 310 on the array substrate 100, the second end 310b can block at least part of the material used to prepare the light-emitting layer 400 when the light-emitting layer 400 of the display panel 10 is deposited, thereby isolating the light-emitting layer 400 between adjacent sub-pixels and facilitating the formation of multiple spaced light-emitting units 410. This eliminates the need to set a high-precision mask when depositing the light-emitting layer 400 of the display panel 10, for example, eliminating the need to set a high-precision metal mask (FMM) when depositing the light-emitting layer 400, thereby reducing the manufacturing cost of the display panel 10.

[0190] In the embodiments of this application, there are various ways to set the shape of the isolation column 310, that is, there are various ways to make the orthographic projection of the first end 310a on the array substrate 100 located within the orthographic projection of the second end 310b on the array substrate 100.

[0191] like Figure 12 As shown, in some embodiments, in the direction away from the array substrate 100, the spacing between the surfaces of the isolation pillar 310 on both sides of the isolation opening 300b gradually increases, so that the orthographic projection of the first end 310a of the isolation pillar 310 on the substrate can be located within the orthographic projection of the second end 310b of the isolation pillar 310 on the substrate.

[0192] Figure 13 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application.

[0193] likeFigure 13 As shown, in some other embodiments, the isolation pillar 310 includes a first isolation portion 311 and a second isolation portion 312 disposed on the side of the first isolation portion 311 away from the array substrate 100, wherein the orthographic projection of the first isolation portion 311 on the array substrate 100 is located within the orthographic projection of the second isolation portion 312 on the array substrate 100.

[0194] Optionally, the first end portion 310a may be located at the first isolation portion 311, and the second end portion 310b may be located at the second isolation portion 312. Optionally, the second isolation portion 312 is provided to protrude from the first isolation portion 311 toward the isolation opening 300b.

[0195] In this embodiment, by setting the orthographic projection of the first isolation portion 311 on the substrate to be within the orthographic projection of the second isolation portion 312 on the substrate, the second isolation portion 312 can block at least part of the material used to prepare the light-emitting layer 400 when the light-emitting layer 400 of the display panel 10 is deposited, thereby isolating the light-emitting layers 400 between adjacent sub-pixels and facilitating the formation of multiple spaced light-emitting units 410. This eliminates the need to set a high-precision mask when depositing the light-emitting layer 400 of the display panel 10, for example, eliminating the need to set a high-precision metal mask when depositing the light-emitting layer 400, thereby reducing the manufacturing cost of the display panel 10.

[0196] In some embodiments, the material of the first isolation portion 311 includes a conductive material, and two adjacent first electrodes 510 are connected through the first isolation portion 311. That is, the first electrodes 510 in adjacent isolation openings 300b can be interconnected through the first isolation portion 311 to form a surface electrode, so as to facilitate the control of the first electrodes 510 in the display panel 10.

[0197] In other embodiments, the material of the first isolation portion 311 may include an insulating material, and the first electrodes 510 in adjacent isolation openings 300b can be mutually insulated by the first isolation portion 311, so that the first electrodes 510 in each isolation opening 300b in the display panel 10 can be independently controlled.

[0198] In some embodiments of this application, there are various ways to set the relative positions between the isolation pillar 310 and the pixel limiting portion 320.

[0199] like Figure 13 As shown, in some embodiments, the isolation pillar 310 can be directly disposed on the pixel limiting portion 320, that is, the isolation pillar 310 can be disposed on the side of the pixel limiting portion 320 away from the array substrate 100.

[0200] Figure 14 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application.

[0201] like Figure 14 As shown, in some other embodiments, the pixel limiting portion 320 has a receiving groove 321, and at least a portion of the isolation pillars 310 can be disposed in the receiving groove 321, so that the isolation structure 300 is less likely to have an excessive height compared to the array substrate 100, thereby effectively reducing the thickness of the display panel 10.

[0202] like Figure 14 As shown, optionally, the light-transmitting opening 300a can be installed through the isolation column 310 to better reduce the light blockage by the isolation column 310, so that the photosensitive component under the light-transmitting opening 300a can better sense light.

[0203] Figure 15 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application.

[0204] like Figure 15 As shown, optionally, the light-transmitting opening 300a can also extend through the isolation pillar 310 and the pixel limiting part 320 to further reduce the light blocking by the isolation structure 300 and further improve the light sensing efficiency of the photosensitive component under the light-transmitting opening 300a.

[0205] In some embodiments of this application, the inner wall surface of the light-transmitting opening 300a can be shaped in various ways. For example... Figure 14 As shown, in some embodiments, the surface shape of the isolation structure 300 facing the light-transmitting opening 300a can be the same as the surface shape of the isolation structure 300 facing the isolation opening 300b. This allows the isolation opening 300b to be fabricated using the same fabrication process as the light-transmitting opening 300a when the isolation structure 300 is fabricated. It also allows the isolation opening 300b to be fabricated together with the light-transmitting opening 300a in the same fabrication step, thereby improving the fabrication efficiency of the display panel 10.

[0206] like Figure 15 As shown, in some other embodiments, the surface shape of the isolation structure 300 facing the light-transmitting opening 300a may be different from the surface shape of the isolation structure 300 facing the isolation opening 300b. The specific shape of the inner wall surface of the light-transmitting opening 300a may be set according to the specific requirements of the light transmittance at the light-transmitting opening 300a, so that light within a specific angle range can pass through the light-transmitting opening 300a better, which facilitates the design of the light transmittance of the display panel 10.

[0207] The display device provided by the second aspect of the present application comprises the display panel 10 of any of the above embodiments. Since the display device provided by the second aspect of the present application comprises the display panel 10 of any of the above embodiments of the first aspect, the display device provided by the second aspect of the present application has the beneficial effects of the display panel 10 of any of the above embodiments of the first aspect, which will not be described here.

[0208] The display device in the embodiments of the present application includes, but is not limited to, a mobile phone, a personal digital assistant (PDA), a tablet computer, an e-book, a television, an access control, a smart fixed telephone, a console, and the like.

[0209] Optionally, the display device can comprise a light-sensing component for sensing light. The light-sensing component can be arranged corresponding to the light-transmitting opening 300a. For example, at least part of the light-sensing component is within the inner wall of the isolation structure 300 surrounding the light-transmitting opening 300a on the substrate, so that the light can be better sensed by the light-sensing component through the light-transmitting opening 300a.

[0210] Optionally, the light-sensing component can be arranged in various ways. For example, the light-sensing component can comprise a distance sensor, a camera, an under-screen fingerprint recognition module, and the like.

[0211] The above is merely a specific implementation of the present application. Those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the above-described system, module, and unit can refer to the corresponding process in the foregoing method embodiments, which will not be described here. It should be understood that the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application.
