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

[0108] The second area AA2 may be provided with a sensor, and the sensor may include at least one of an ambient light sensor, a camera, a fingerprint sensor, etc. The second area AA2 may have a display function, or may not have a display function, which is not specifically limited here.

[0109] The light-transmitting opening 300a located in the second area AA2 and opened in the isolation structure 300 can better allow 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 used for sensing light in the display device can be correspondingly arranged under the light-transmitting opening 300a, so that the photosensitive component can better sense light through the light-transmitting opening 300a.

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

[0111] Optionally, the light-transmitting opening 300a may be disposed only in the second area AA2, that is, the light-transmitting opening 300a may not be disposed in the first area AA1, so that the second area AA2 in the display panel 10 can have a good light transmittance, and the first area AA1 in the display panel 10 can have a relatively sufficient area to set the isolation opening 300b, so that the first area AA1 can have a larger number of isolation openings 300b, that is, the first area AA1 can have denser sub-pixels, which can better improve the pixel arrangement density (Pixels Per Inch, PPI) of the first area AA1, thereby better improving the display effect of the display panel 10. In addition, since the first area AA1 is not provided with the light-transmitting opening 300a, it is also difficult for the signal in the array substrate 100 to crosstalk with the touch signal in the first area AA1, thereby better improving the working reliability of the display panel 10.

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

[0113] Optionally, both the first area AA1 and the second area AA2 have a light-emitting unit 410 in the isolation opening 300b. For example, both the first area AA1 and the second area AA2 are provided with a first electrode 510, a light-emitting unit 410 and a second electrode 210, so that both the first area AA1 and the second area AA2 have sub-pixels capable of emitting light, thereby better improving the screen-to-body ratio of the display panel 10.

[0114] There are many ways to set the size and arrangement shape of each isolation opening 300b. Optionally, the size and arrangement shape of each isolation opening 300b can be set according to the light color of the light-emitting unit 410 in the isolation opening 300b. Optionally, the size and arrangement shape of each isolation opening 300b can also be set according to the pixel arrangement density requirement of the display panel 10.

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

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

[0117] By reasonably setting the arrangement positions of the light-transmitting openings 300 a , it is possible to prevent the light-transmitting openings 300 a not provided with related light-emitting devices from being arranged in a relatively concentrated manner, thereby improving the display uniformity of the display panel 10 .

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

[0119] Optionally, the touch area 600a can be set in the first area AA1, so that the display panel 10 in the first area AA1 can have a touch sensing function through the touch electrode 610 in the touch area 600a, and the touch electrode 610 in the touch area 600a is not easily interfered by the signal in the array substrate 100 leaked through the light-transmitting opening 300a in the second area AA2.

[0120] In some optional embodiments, the virtual electrodes 620 may not be connected to the touch signal lines, that is, the virtual electrodes 620 in the non-touch area 600 b do not participate in the touch sensing operation of the display panel 10 .

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

[0122] By setting the virtual electrode 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 a similar film thickness, so that the display panel 10 can have a better flatness, and it is not easy to have too large reflectivity or visual color deviation difference between the touch area 600a and the non-touch area 600b, so that the display panel 10 can have a better optical image quality and display uniformity. In addition, the virtual electrode 620 set in the non-touch area 600b can also play a certain shielding and shielding role on the crosstalk between the touch signal and the signal in the array substrate 100, which can improve the light emission stability and touch stability of the display panel 10.

[0123] Optionally, at least part of the non-touch area 600b may be disposed in the second area AA2. Optionally, the orthographic projection of the inner wall of the isolation structure 300 surrounding the light-transmitting opening 300a on the touch layer 600 is located in the non-touch area 600b.

[0124] In these optional embodiments, by reasonably setting the positional relationship between the second area AA2 and the non-touch area 600b, or by reasonably setting the positional relationship between the light-transmitting opening 300a and the non-touch area 600b, the non-touch area 600b can better cover the second area AA2 or the top of the light-transmitting opening 300a, so that the virtual electrode 620 can play a certain shielding and shielding role on the signal in the array substrate 100 that is easy to leak out through the light-transmitting opening 300a in the second area AA2, so that the signal in the array substrate 100 that leaks out through the light-transmitting opening 300a in the second area AA2 is not easy to 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 light to pass through better so that the light can be sensed by the photosensitive component. Optionally, the second area AA2 can be used to allow light to pass through better so as to facilitate the sensing of the sensor, for example, it can facilitate the infrared light emitting diode (IR-LED) on one side of the display panel 10 to approach the sensor.

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

[0127] For example, at least a portion of the second area AA2 may also be used to allow light to pass through better, so as to facilitate sensing by 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 touch area 600a to participate in 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 likely to block the isolation opening 300b and the light-transmitting opening 300a opened on the isolation structure 300 in the thickness direction X of the display panel 10, thereby making it difficult for the setting of the virtual electrode 620 to block the luminous display of the display panel 10, and also making it difficult for the virtual electrode 620 to affect the transmittance of the display panel 10 at the light-transmitting opening 300a.

[0130] In some optional embodiments, the orthographic projection of the touch electrode 610 on the array substrate 100 is located within the orthographic projection of the isolation structure 300 on the array substrate 100, so that the touch electrode 610 is not likely to block the isolation opening 300b opened on the isolation structure 300 in the thickness direction X of the display panel 10, thereby making it difficult for the setting of the touch electrode 610 to block the luminous display of the display panel 10.

[0131] In some optional embodiments, the orthographic projection of the virtual electrode 620 on the isolation structure 300 is arranged around at least a portion of the isolation opening 300b, and / or the orthographic projection of the virtual electrode 620 on the isolation structure 300 is arranged around at least a portion of the light-transmitting opening 300a, so that the virtual electrode 620 is not easy to block the luminous display of the display panel 10 and is not easy to affect the transmittance of the display panel 10 at the light-transmitting opening 300a, and the virtual electrode 620 can also have a better wiring area, thereby being able to enhance the shielding and shielding effect of the virtual electrode 620 on the crosstalk between the touch signal and the signal in the array substrate 100.

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

[0133] Optionally, the orthographic 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 is not easy to block the luminous display of the display panel 10, and the touch electrode 610 can also have a better wiring area, thereby improving the touch sensing capability of the display panel 10.

[0134] Optionally, the touch electrode 610 is in a grid shape, wherein the hollow areas in the grid-shaped touch electrode 610 may be arranged corresponding to the isolation opening 300b, that is, the hollow areas in the grid-shaped touch electrode 610 may be located on a side of the isolation opening 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 is arranged around at least a portion of the isolation opening 300b, and the orthographic projection of the touch electrode 610 on the isolation structure 300 is arranged around at least a portion of the isolation opening 300b, the extended shape of the touch electrode 610 may be similar to the extended shape of the virtual electrode 620. For example, the virtual electrode 620 and the touch electrode 610 may both be in a grid shape, thereby preventing excessive reflectivity or visual color deviation differences between the touch area 600a and the non-touch area 600b, and also allowing the display panel 10 to 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 side 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 side 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 side 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 side 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 side surfaces of the isolation structure 300 facing the light-transmitting opening 300a.

[0137] Optionally, the width of the touch electrode 610 may be equal to the maximum width of the isolation structure 300 , so that the touch electrode 610 can have a better width to transmit a touch signal, 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 distance 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. 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 the 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 the second spacing L2, and the first spacing L1 and the second spacing L2 can both be greater than or equal to 1.5μm. This can improve the problem that the light-transmitting opening 300a and / or the isolation opening 300b is easily blocked when the manufacturing process of the virtual electrode 620 fluctuates, which helps to ensure the product yield, thereby improving the display effect and light transmittance of the second area AA2.

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

[0140] In some optional embodiments, the touch layer 600 may include an insulating portion 630 disposed between the touch electrode 610 and the dummy electrode 620. Optionally, the material of the insulating portion 630 may 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 through the insulating portion 630, so that the touch signal in the touch electrode 610 is not easy to crosstalk with the signal in the array substrate 100 through the dummy electrode 620.

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

[0142] Optionally, the orthographic projection of the insulating portion 630 on the array substrate 100 may be located within the orthographic projection of the isolation structure 300 on the array substrate 100, so that the insulating portion 630 may be disconnected on the side of the isolation opening 300b facing away from the substrate, making it difficult for the insulating portion 630 to block the isolation opening 300b opened on the isolation structure 300 in the thickness direction X of the display panel 10, thereby making it difficult for the setting of the insulating portion 630 to block the luminous 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 may 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 may be equal to the size of the virtual electrode 620 in the thickness direction X of the display panel 10, so that the touch layer 600 can have a more uniform thickness and the display panel 10 can have better flatness.

[0144] Figure 4 It is a partially enlarged schematic diagram of a touch layer 600 and an isolation structure 300 provided in another embodiment of the present application.

[0145] like Figure 4 As shown, in some other optional embodiments, the touch layer 600 further includes a partition groove 640 disposed between the touch electrode 610 and the dummy electrode 620. Optionally, the partition groove 640 may be disposed through the touch layer 600.

[0146] By providing a partition groove 640 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 through the partition groove 640 , so that the touch signal in the touch electrode 610 is not likely to crosstalk with the signal in the array substrate 100 through the dummy electrode 620 .

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

[0148] Figure 5 It is a partial enlarged schematic diagram of a touch layer 600 and an isolation structure 300 provided in yet another embodiment of the present application.

[0149] like Figure 5 As shown, in some optional embodiments, the number of virtual electrodes 620 can also be at least two, and adjacent virtual electrodes 620 are arranged at intervals. By setting the number of virtual electrodes 620 to be multiple and arranging them at intervals, the arrangement of the virtual electrodes 620 can be better facilitated.

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

[0151] like Figure 6 and Figure 7 As shown, in some optional embodiments, a plurality of isolation openings 300b are spaced apart in the first preset direction J and the second preset direction K, a portion of the virtual electrodes 620 are located between adjacent isolation openings 300b in the first preset direction J, and another portion of the virtual electrodes 620 are located between adjacent isolation openings 300b in the second preset direction K, wherein 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 electrode 621 and a second type electrode 622 . The first type electrode 621 is located between adjacent isolation openings 300 b in the first preset direction J, and the second type electrode 622 is located between adjacent isolation openings 300 b in the second preset direction K.

[0153] In this 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 compactness of the arrangement of the isolation openings 300b and the light-emitting units 410 in the isolation openings 300b. At the same time, by arranging the dummy electrodes 620 along the arrangement direction of the isolation openings 300b and arranging them between adjacent isolation openings 300b, the size of the isolation structure 300 between adjacent isolation openings 300b in the first preset direction J and the second preset direction K can be better utilized to arrange the dummy electrodes 620, thereby improving the compactness of the arrangement of the isolation openings 300b and the dummy electrodes 620.

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

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

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

[0157] In these optional embodiments, by arranging 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 spacing space can be provided between the first type of electrodes 621 and the second type of electrodes 622 to facilitate the arrangement of the light-transmitting openings 300a. By arranging the light-transmitting openings 300a between two adjacent first type electrodes 621 in the second preset direction K and two adjacent second type electrodes 622 in the first preset direction J, the plurality of isolation openings 300b can be better surrounded by the peripheral side of the light-transmitting openings 300a, and the light-transmitting openings 300a can be arranged above the portion of the isolation structure 300 with a larger size between the plurality of isolation openings 300b, so as to facilitate the arrangement of the larger light-transmitting openings 300a, thereby better improving the arrangement compactness of the isolation openings 300b, the light-transmitting openings 300a and the virtual electrodes 620. Furthermore, the virtual electrode 620 and the light-transmitting opening 300a will not be simultaneously arranged on the portion of the isolation structure 300 between two adjacent isolation openings 300b, which can improve the problem of the virtual electrode 620 easily blocking the light-transmitting opening 300a and / or the isolation opening 300b when the preparation process of the virtual electrode 620 fluctuates, and also allow a smaller gap between two adjacent isolation openings 300b to facilitate the arrangement of larger or more isolation openings 300b, thereby improving the display effect of the display panel 10.

[0158] In some embodiments of the present application, the first direction Y and the second direction Z may be the main extension directions of the entire display panel 10 , and the user may mainly view the luminous display content of the display panel 10 in the first direction Y and the second direction Z.

[0159] Optionally, there are various relative position settings of 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, there are various ways to set the shape of the isolation opening 300b. For example, the shape of the orthographic projection of the inner wall of the isolation structure 300 enclosing the isolation opening 300b on the array substrate 100 may 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 may be parallel to the first direction X, and the second preset direction K may be parallel to the second direction Z, that is, the isolation openings 300b may be arranged to be spaced apart along the length direction and the width direction of the display panel.

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

[0163] like Figure 8 As shown, in other embodiments, the first preset direction J may intersect with the first direction X, and the second preset direction K may intersect with the second direction Z, so as to better arrange the isolation openings according to the specific shape of the isolation openings 300b.

[0164] Optionally, the angle range between the first preset direction J and the first direction X can be 30° to 60°, and the angle range between the second preset direction K and the second direction Z can also be 30° to 60°, so that the arrangement of the isolation opening 300b can also be relatively uniform in the first direction Y and the second direction Z, and is not easy to affect the color deviation of the display panel in the first direction Y and the second direction Z.

[0165] Optionally, the angle between the first preset direction J and the first direction X may be 45°, and the angle between the second preset direction K and the second direction Z may also be 45°. In addition, the angle between the first preset direction J and the first direction X may be 40° or 50°, and the angle between the second preset direction K and the second direction Z may also be 40° or 50°, which are not specifically limited herein.

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

[0167] like Figure 6 and Figure 7 As shown, optionally, when the first preset direction J is parallel to the first direction X and the second preset direction K is parallel to the second direction Z, at least two first-type electrodes 621 on at least part of the peripheral side of the isolation opening 300b may be symmetrically arranged about the second symmetry axis S2, and at least two second-type electrodes 622 on at least part of the peripheral side of the isolation opening 300b may be symmetrically arranged about the first symmetry axis S1.

[0168] Fig. 9 is a partially enlarged schematic diagram of an isolation structure 300 and a virtual electrode 620 provided in another embodiment of the present application. Fig.10 It is a partially enlarged schematic diagram of an isolation structure 300 and a virtual electrode 620 provided in yet another embodiment of the present application.

[0169] like Figures 8 to 10As shown, optionally, when the first preset direction J intersects with the first direction X and the second preset direction K intersects with the second direction Z, the first type of electrode 621 on at least part of the peripheral side of the isolation opening 300b may be symmetrically arranged with the second type of electrode 622 on the peripheral side of the isolation opening 300b about the first symmetry axis S1, and / or, the first type of electrode 621 on at least part of the peripheral side of the isolation opening 300b may be symmetrically arranged with the second type of electrode 622 on the peripheral side of the isolation opening 300b about the second symmetry axis S2.

[0170] By setting the virtual electrodes 620 symmetrically about the first symmetry axis S1 and the second symmetry axis S2, the virtual electrodes 620 on the periphery of the isolation opening 300b can be arranged more evenly, so that the symmetrical virtual electrodes 620 have similar effects on the color deviation of the light-emitting unit 410 in the isolation opening 300b, so as to better reduce the color deviation in the second area AA2, thereby better improving the display uniformity of the second area AA2.

[0171] like Fig. 9 and Fig.10 As shown, in some optional embodiments, the light emitting unit 410 may include a first light emitting unit, and the isolation opening 300b may include a first type of opening 300c accommodating the first light emitting unit, and the first type of opening 300c may 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 geometric center points of the plurality of light-transmitting openings 300a are connected to form a virtual polygon, and the first symmetry axis S1 and / or the second symmetry axis S2 are diagonals of the virtual polygon. Fig. 9 and Fig.10 In the illustrated embodiment, four light-transmitting openings 300a are arranged around the same first-type opening 300c. The geometric center points of the four light-transmitting openings 300a are connected to form a virtual quadrilateral. The first symmetry axis S1 and the second symmetry axis S2 are two diagonals of the virtual quadrilateral.

[0173] In the above embodiment, by reasonably arranging the positions of the first type of opening 300c and the virtual electrode 620, and making the virtual electrode 620 more evenly arranged around the first type of opening 300c, the virtual electrode 620 has a similar effect on the color deviation of the first light-emitting unit in the first type of opening 300c, thereby being able to better reduce the color deviation in the second area AA2.

[0174] Optionally, the light color of the first light emitting unit is red light or blue light. Fig. 9 As shown, part of the first type of openings 300c can be used to accommodate the first light-emitting unit that emits red light. Fig.10As shown, part of the first type openings 300c can be used to accommodate the first light emitting unit emitting blue light.

[0175] Fig.11 It is a partially enlarged schematic diagram of an isolation structure 300 and a virtual electrode 620 provided in another embodiment of the present application.

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

[0177] When the first preset direction J intersects with the first direction X and the second preset direction K intersects with the second direction Z, the second type of openings 300d are arranged symmetrically about the third symmetry axis S3 and / or the fourth symmetry axis S4, that is, the shape of the second type of openings 300d is reasonably set to facilitate the arrangement of the second type of openings 300d, so that the isolation structure 300 can be better arranged in the first preset direction J and the second preset direction K.

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

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

[0180] In these optional embodiments, by arranging at least two virtual electrodes 620 symmetrically about the third symmetry axis S3 and at least two virtual electrodes 620 symmetrically about the fourth symmetry axis S4, the virtual electrodes 620 can be arranged more evenly around the second type of opening 300d, so that the virtual electrodes 620 have a similar effect on the color deviation of the second light-emitting unit in the second type of opening 300d, thereby better reducing the color deviation in the second area AA2.

[0181] Optionally, the light emitting color of the second light emitting unit is green, and the second type of opening 300c can be used to accommodate the second light emitting unit emitting green light.

[0182] In some embodiments of the present application, the relative position relationship or relative area relationship between the touch area 600a and the non-touch area 600b can be adjusted to further reduce the crosstalk between the touch signal in the touch electrode 610 and the signal in the array substrate 100. 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 there is a relatively sufficient distance between the setting position of the touch electrode 610 and the light-transmitting opening 300a, so that the signal in the array substrate 100 is not easily affected by the light-transmitting opening 300a to the touch signal in the touch electrode 610 at a farther distance, thereby effectively reducing the crosstalk between the touch signal in the touch electrode 610 and the signal in the array substrate 100.

[0184] Optionally, the maximum spacing between the boundaries of the non-touch area 600b may be less than or equal to 3 mm. For example, the size of the non-touch area 600b in any direction perpendicular to the thickness direction X of the display panel 10 may be less than or equal to 3 mm, so that the virtual electrode 620 does not have an excessively large area and thus affects the overall touch sensing capability of the display panel 10. Although the virtual electrode 620 in the non-touch area 600b within this range cannot participate in the touch sensing work, the touch reporting point in the non-touch area 600b can be compensated by reasonably setting the algorithm of the touch control circuit in the display device, so that the display panel 10 can still have a good touch sensing capability.

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

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

[0187] Optionally, the pixel defining 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 defining portion 320, at least a portion of the second electrode 210 can be exposed from the pixel opening 320a, and at least a portion of the light-emitting unit 410 can be located in the pixel opening 320a, so that at least a portion of the second electrode 210 can 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 Fig.12 As shown, in some optional embodiments, the isolation structure 300 may include an isolation column 310, which has a first end 310a and a second end 310b relative to 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 column 310 on the array substrate 100 to be within the orthographic projection of the second end 310b of the isolation column 310 on the array substrate 100, when the light-emitting layer 400 of the display panel 10 is evaporated, the second end 310b can block at least a portion of the material used to prepare the light-emitting layer 400 to separate the light-emitting layer 400 between adjacent sub-pixels, and can facilitate the formation of a plurality of light-emitting units 410 arranged at intervals, so that when the light-emitting layer 400 of the display panel 10 is evaporated, there is no need to set a mask with high precision, for example, when the light-emitting layer 400 is evaporated, there is no need to set a high-precision metal mask (Fine Metal Mask, FMM), thereby reducing the production cost of the display panel 10.

[0190] In the embodiment of the present application, there are multiple ways to set the shape of the isolation column 310, that is, there are multiple ways to achieve that 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.

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

[0192] Fig.13 It is a partial cross-sectional view of a display panel 10 provided in yet another embodiment of the present application.

[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 disposed 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, when the light-emitting layer 400 of the display panel 10 is evaporated, the second isolation portion 312 can block at least a portion of the material used to prepare the light-emitting layer 400 to separate the light-emitting layer 400 between adjacent sub-pixels, and can facilitate the formation of a plurality of spaced light-emitting units 410, so that when the light-emitting layer 400 of the display panel 10 is evaporated, there is no need to set a mask plate with high precision, for example, when the light-emitting layer 400 is evaporated, there is no need to set a high-precision metal mask plate, thereby reducing the production 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 electrode 510 in the display panel 10.

[0197] In other embodiments, the material of the first isolation portion 311 may include insulating material, and the first electrodes 510 in adjacent isolation openings 300b may be insulated from each other 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 the present application, there are multiple ways to set the relative positions of the isolation column 310 and the pixel defining portion 320 .

[0200] Fig.14 It is a partial cross-sectional view of a display panel 10 provided in yet another embodiment of the present application.

[0201] like Fig.14 As shown, in other embodiments, the pixel defining portion 320 is provided with a receiving groove 321, and at least part of the isolation column 310 can be arranged in the receiving groove 321, so that the isolation structure 300 is less likely to have an excessively large height compared to the array substrate 100, thereby being able to better reduce the thickness of the display panel 10.

[0202] like Fig.14 As shown, optionally, the light-transmitting opening 300a may be arranged to penetrate the isolation column 310 to better reduce the shielding of light by the isolation column 310, so that the photosensitive component under the light-transmitting opening 300a can better sense light.

[0203] Fig.15 It is a partial cross-sectional view of a display panel 10 provided in another embodiment of the present application.

[0204] like Fig.15 As shown, optionally, the light-transmitting opening 300a may also be provided through the isolation column 310 and the pixel defining portion 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 the present application, there are many ways to set the shape of the inner wall surface of the light-transmitting opening 300a. Fig.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, so that when preparing the isolation structure 300, the isolation opening 300b can be prepared using the same preparation process as the light-transmitting opening 300a, and the isolation opening 300b can be prepared together with the light-transmitting opening 300a in the same preparation step, thereby better improving the preparation efficiency of the display panel 10.

[0206] like Fig.15 As shown, in 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 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 is convenient for the design of the transmittance of the display panel 10.
