[0017] 1 to 3, an embodiment of the present application provides a display panel including an array substrate 100, an isolation structure 200, and a light-emitting unit 400. The array substrate 100 includes a substrate 120 and a metal structure 110 disposed on the substrate 120. The isolation structure 200 is disposed on one side of the array substrate 100 and surrounds and closes the substrate 120 to form a plurality of isolation openings 210 and light-transmitting holes 220. The orthogonal projections of the light-transmitting holes 220 on the substrate 120 and the orthogonal projections of the metal structure 110 on the substrate 120 are at least partially misaligned. The light-emitting units 400 are disposed corresponding to the isolation openings 210, and the orthogonal projections of the light-transmitting holes 220 on the substrate 120 have recesses 220d.

[0018] Preferably, the light emitting unit 400 includes a first electrode 410, a light emitting functional layer 420, and a second electrode 430, which are stacked in a direction away from the substrate 120. The light emitting unit 400 being disposed in correspondence with the isolation opening 210 means that at least a portion of the light emitting unit 400 is located within the isolation opening 210, for example, the light emitting functional layer 420 and at least a portion of the second electrode 430 of the light emitting unit 400 are located within the isolation opening 210.

[0019] In the present embodiment, the display panel includes an array substrate 100 and an isolation structure 200. The isolation structure 200 encloses and defines an isolation opening 210 and a light-transmitting hole 220. The isolation opening 210 is used to accommodate at least some of the light-emitting units 400, thereby reducing crosstalk between adjacent light-emitting units 400 and realizing light-emitting display of the display panel. The array substrate 100 includes a substrate 120 and a metal structure 110 disposed on the substrate 120. The metal structure 110 can be used to drive the light-emitting units 400. The light-transmitting hole 220 is used to improve the light transmittance of the display panel and facilitate under-display integration of a light-sensing module. The orthogonal projection of the light-transmitting hole 220 on the substrate 120 and the orthogonal projection of the metal structure 110 on the substrate 120 are at least partially offset, thereby improving the influence of the metal structure 110 on the light-transmitting hole 220. At least one light-transmitting hole 220 has a recess 220d, and the distance between the orthogonal projection of the recess 220d on the substrate 120 and the orthogonal projection of the isolation opening 210 on the substrate 120 is reduced, thereby increasing the distribution area of ​​the light-transmitting holes 220 as much as possible and alleviating the signal interference problem caused by exposure of many metal structures 110 through the light-transmitting holes 220, thereby improving the usability of the display panel.

[0020] Preferably, at least one group of adjacent light-transmitting holes 220 and isolating openings 210 has a preset direction from the center of one to the center of the other, for example, the preset direction is the X direction in Fig. 2, and the minimum spacing distance between the edge of the recess 220d and the edge of the isolating opening 210 in the preset direction is greater than or equal to the preset distance h. This reduces the distance between the recess 220d and the isolating opening 210, thereby increasing the distribution area of ​​the light-transmitting holes 220 as much as possible.

[0021] Preferably, in at least one group of adjacent light-transmitting holes 220 and isolating openings 210 along the preset direction, among the orthogonal projections on the substrate 120, the orthogonal projections of the isolated openings 210 on the substrate 120 have protrusions 210a corresponding to the recesses 220d, so that the adjacent isolated openings 210 can better match the shapes of the light-transmitting holes 220 and maximize the distribution area of ​​the light-transmitting holes 220.

[0022] Preferably, the shapes of at least a part of the region of the protrusion 210a and at least a part of the region of the recess 220d are matched, thereby increasing the distribution area of ​​the light-transmitting holes 220 as much as possible.

[0023] Preferably, the light-transmitting hole 220 comprises a first light-transmitting hole 221 and a second light-transmitting hole 222, the first light-transmitting hole 221 and the second light-transmitting hole 222 being located on the circumferential side of the same isolation opening 210, and the orthographic projection area of ​​the first light-transmitting hole 221 on the substrate 120 is larger than the orthographic projection area of ​​the second light-transmitting hole 222 on the substrate 120.

[0024] In these preferred embodiments, the distribution areas of the metal structures 110 corresponding to the periphery of the same isolating opening 210 on the array substrate 11 are generally different, and the orthographic projection areas of the first light-transmitting hole 221 and the second light-transmitting hole 222 of the light-transmitting hole 220 on the substrate are different, so that the user can reasonably set the dimensions of the first light-transmitting hole 221 and the second light-transmitting hole 222 based on the distribution of the metal structures 110 on the substrate to better match the distribution pattern of the metal structures 110 on the substrate, thereby maximizing the distribution area of ​​the light-transmitting holes 220.

[0025] Preferably, a driving circuit is provided in the array substrate 100, and at least a part of the metal structure 110 is used to form the driving circuit. Preferably, the orthogonal projection of at least a part of the light-transmitting holes 220 on the array substrate 100 is located outside the orthogonal projection of the driving circuit T on the array substrate 100.

[0026] The orthogonal projection of the light-transmitting hole 220 on the substrate 120 and the orthogonal projection of the metal structure 110 on the substrate 120 being at least partially misaligned means that the orthogonal projection of the same light-transmitting hole 220 on the substrate 120 and the orthogonal projection of the metal structure 110 on the substrate 120 are at least partially misaligned, and the metal structure 110 is not provided in at least a part of the same light-transmitting hole 220. Preferably, the orthogonal projection of the light-transmitting hole 220 on the substrate 120 is located outside the orthogonal projection of the metal structure 110 on the substrate 120, or the orthogonal projection of part of the light-transmitting hole 220 on the substrate 120 may overlap with the orthogonal projection of the metal structure 110 on the substrate 120, and the orthogonal projection of another part of the light-transmitting hole 220 on the substrate 120 may be located outside the orthogonal projection of the metal structure 110 on the substrate 120.

[0027] Preferably, the display panel further includes a pixel defining layer 300, which is disposed on the array substrate 100 and includes a pixel defining portion 310 and a pixel opening 320 formed in the pixel defining portion 310, the pixel opening 320 communicating with the isolation opening 210, the light emitting unit 400 disposed corresponding to the pixel opening, and some of the structures located within the pixel opening 320. The isolation structure 200 may be disposed on a side of the pixel defining portion 310 that is away from the array substrate 100, or the pixel defining portion 310 may have a position retraction opening, and the isolation structure 200 may be located within the position retraction opening and directly connected to the array substrate 100. Preferably, the material of the pixel defining layer 300 may be an inorganic material, which can appropriately reduce the thickness of the pixel defining layer 300 and the overall thickness of the display panel 10.

[0028] Preferably, the distance between at least a part of the edge of the light-transmitting hole 220 in the orthogonal projection on the array substrate 100 and at least a part of the edge of the isolation opening 210 in the orthogonal projection on the array substrate 100 is greater than or equal to the preset distance h, which can improve the interaction between the isolation opening 210 and the light-transmitting hole 220.

[0029] The preset distance h of the light transmitting hole 220 can have a range of values, and the preset distance h can be 3 μm to 4 μm, for example, 3 μm, 3.2 μm, 3.5 μm, 3.8 μm, 4 μm, etc., which prevents the preset distance h from being too large and affecting the opening area of ​​the light transmitting hole 220, or the preset distance h from being too small and affecting the positional stability of the light transmitting hole 220 and the isolating opening 210. The preset distance h is not fixed due to actual process variations, and even if an upper or lower error occurs, it is within the protection range.

[0030] There are several ways to install the isolation structure 200. As shown in FIG. 3, the isolation structure 200 may include a first sub-layer 201 and a second sub-layer 202 stacked in a direction away from the array substrate 100. The orthogonal projection of the first sub-layer 201 on the array substrate 100 is located within the orthogonal projection of the second sub-layer 202 on the array substrate 100. That is, the second sub-layer 202 protrudes from the side of the first sub-layer 201, and the dimensions of the first sub-layer 201 are smaller than those of the second sub-layer 202. This allows a recessed structure to be formed on the side of the second sub-layer 202 facing the substrate 120. When the light-emitting units 400 are subsequently manufactured, the light-emitting material is blocked by the isolation structure 200, and the light-emitting units 400 corresponding to the isolation openings 210 can be formed independently of each other.

[0031] 4, the isolation structure 200 may further include a third sub-layer 203 located on the side of the first sub-layer 201 facing the array substrate 100, where the orthogonal projection of the first sub-layer 201 on the array substrate 100 is located within the orthogonal projection of the third sub-layer 203 on the array substrate 100, i.e., the dimensions of the first sub-layer 201 are smaller than the dimensions of the third sub-layer 203. During the manufacturing process of the first sub-layer 201, the third sub-layer 203 can provide protection for the film layer located on the side of the isolation structure 200 facing the array substrate 100.

[0032] Preferably, the light-emitting unit 400 includes a first electrode 410, a light-emitting functional layer 420, and a second electrode 430, which are stacked in a direction away from the array substrate 100. The first electrode 410 may be located on the array substrate 100, or may be located within the pixel opening 320, or may have an edge surrounded by the pixel limiting portion 310 and exposed from the pixel opening 320. The light-emitting functional layer 420 is located within the pixel opening 320. Preferably, the material of the isolation structure 200 may include a conductive material, and the second electrode 430 and the isolation structure 200 are overlapping and connected to each other, so that the second electrodes 430 can be connected to each other by the isolation structure 200 to form planar electrodes.

[0033] In some preferred embodiments, in adjacent light-transmitting holes 220 and isolation openings 210, as shown in Figures 2 and 7, the orthogonal projection of recess 220d on substrate 120 has a first side edge 230 facing the orthogonal projection of isolation opening 210 on substrate 120, and the orthogonal projection of protrusion 210a on substrate 120 has a second side edge 240 facing the first side edge 230, and the distance between first side edge 230 and second side edge 240 is a preset distance h.

[0034] In these preferred embodiments, the recessed portion 220d is recessed to form the first side edge 230, and the protruding portion 210a is protruded to form the second side edge 240, and the minimum distance between the first side edge 230 and the second side edge 240 along the preset direction is greater than or equal to the preset distance h, so that the distance between the first side edge 230 and the second side edge 240 is small, thereby making it possible to maximize the opening size of the light-transmitting hole 220.

[0035] 7, the shapes of the first side 230 and the second side 240 are matched to each other, thereby increasing the distribution area of ​​the light-transmitting holes 220 as much as possible and improving the interaction between the light-transmitting holes 220 and the isolation openings 210.

[0036] Preferably, the first side edge 230 and the second side edge 240 are equally spaced apart. The first side edge 230 and the second side edge 240 are equally spaced apart within a process tolerance range. For example, the second side edge 240 is an arc-shaped edge that protrudes along a direction away from the center of the isolation opening 210, and the first side edge 230 is an arc-shaped edge that is recessed along a direction away from the center of the isolation opening 210 and toward the inside of the first light transmitting hole 221. Thus, the first side edge 230 and the second side edge 240 can be equally spaced apart.

[0037] In these preferred embodiments, the first side edge 230 and the second side edge 240 are equally spaced apart to ensure that the light-transmitting holes 220 have a sufficiently large distribution area, and to improve the influence of the light-transmitting holes 220 on the isolation opening 210.

[0038] Preferably, the first side edge 230 and the second side edge 240 have an arc shape. Preferably, in order to improve the diffraction phenomenon between the light emitting units 400 of different colors, the shape of the isolated openings 210 when orthogonally projected on the array substrate 100 is a circle, an ellipse, etc. The embodiments of the present application will be described taking the shape of the isolated openings 210 when orthogonally projected on the array substrate 100 as an ellipse, and in this case, the second side edge 240 is a part of the ellipse. The first side edge 230 may also be a part of an ellipse, so that the first side edge 230 and the second side edge 240 both have an arc shape and may be equally spaced apart.

[0039] Preferably, the first side edge 230 may be provided at the first light transmitting hole 221 and / or the second light transmitting hole 222 .

[0040] Preferably, the first side edge 230 has a first sub-edge 231 provided in the first light-transmitting hole 221 and facing the isolation opening 210, and a second sub-edge 232 provided in the second light-transmitting hole 222 and facing the isolation opening 210, and the length of the first sub-edge 231 in the second direction Y is smaller than the length of the second sub-edge 232 in the second direction Y.

[0041] In these preferred embodiments, the first light-transmitting hole 221 has a first sub-edge 231, and the second light-transmitting hole 222 has a second sub-edge 232, and the length of the first sub-edge 231 is smaller than the length of the second sub-edge 232, so that the distribution area of ​​the first light-transmitting hole 221 is larger than the distribution area of ​​the second light-transmitting hole 222.

[0042] Preferably, the second side 240 has a third sub-edge 241 facing the first sub-edge 231 and a fourth sub-edge 242 facing the second sub-edge 232, and the spacing between the first sub-edge 231 and the third sub-edge 241 may be equal to the spacing between the second sub-edge 232 and the fourth sub-edge 242. Alternatively, the spacing between the first sub-edge 231 and the third sub-edge 241 may be smaller than the spacing between the second sub-edge 232 and the fourth sub-edge 242, so that the first light-transmitting holes 221 and the second light-transmitting holes 222 can better fit the distribution pattern of the metal structures 110 in the array substrate 100.

[0043] The light-transmitting hole 220 may have an overall shape of an inwardly concave polygon, one of whose sides is the first side 230 .

[0044] Preferably, the inner wall of the light-transmitting hole 220 has a recess 220d recessed along a direction away from the isolation opening 210, and the first side edge 230 is located in the recess 220d. In these preferred embodiments, in order to fit the circular or elliptical isolation opening 210, the light-transmitting hole 220 has the recess 220d and the first side edge 230 is located in the recess 220d, thereby achieving the objective of the first side edge 230 and the second side edge 240 being equally spaced apart.

[0045] In some embodiments, the light-transmitting hole 220 is located on one side of the isolation opening 210 in the first direction X, and has a first straight edge 220a that is offset from the first side edge 230 along the first direction X, and the first straight edge 220a extends linearly along the second direction Y. By providing the light-transmitting hole 220 with one straight edge and one side edge, the shape of the light-transmitting hole 220 can be adapted to the shape of the isolation opening 210, and the size of the light-transmitting hole 220 can be made as large as possible to increase the light transmittance.

[0046] Preferably, to further simplify the distribution pattern of the light transmitting holes 220, the first straight side 220a is connected to the second straight side 220b at both ends in the second direction Y, and the second straight side 220b extends linearly along the first direction X. The second straight side 220b may be provided on at least one of the first light transmitting holes 221 and the second light transmitting holes 222.

[0047] Preferably, when the first side edge 230 is provided in the first light transmitting hole 221 and the first light transmitting hole 221 has a first sub-edge 231, the first sub-edge 231 and the first straight side 220a are spaced apart from each other in the first direction X. When the first side edge 230 is provided in the second light transmitting hole 222 and the second light transmitting hole 222 has a second sub-edge 232, the second sub-edge 232 and the first straight side 220a are spaced apart from each other in the first direction X.

[0048] Preferably, to further simplify the distribution pattern of the light transmitting holes 220, the first straight side 220a is connected to the second straight side 220b at both ends in the second direction Y, and the second straight side 220b extends linearly along the first direction X. The second straight side 220b may be provided on at least one of the first light transmitting holes 221 and the second light transmitting holes 222.

[0049] Preferably, the first side 230 has a third straight side 220c on at least one side in the second direction Y, the third straight side 220c extending linearly along the second direction Y, and the first side 230 is connected to the second straight side 220b via the third straight side 220c. If the first side 230 has a first sub-edge 231, the first sub-edge 231 can be connected to the second straight side 220b via the third straight side 220c, and if the first side 230 has a second sub-edge 232, the second sub-edge 232 can be connected to the second straight side 220b via the third straight side 220c, thereby further increasing the distribution area of ​​the light-transmitting holes 220 and further simplifying the shape of the light-transmitting holes 220.

[0050] Preferably, each light-transmitting hole 220 may have two third straight edges 220c, i.e., the first side edge 230 has a third straight edge 220c on both sides in the second direction Y, and both ends of the first side edge 230 are connected to the second straight edge 220b via the third straight edges 220c, thereby further increasing the distribution area of ​​the light-transmitting holes 220. Preferably, both ends of the first sub-edge 231 may be connected to the second straight edge 220b via the third straight edges 220c. Preferably, both ends of the second sub-edge 232 may be connected to the second straight edge 220b via the third straight edges 220c.

[0051] Preferably, the first straight edge 220a has a first midpoint P1 extending along the first direction X, and the first side edge 230 is arranged symmetrically about the first midpoint P1, thereby further simplifying the shape of the light-transmitting hole 220. The first midpoint P1 passes through the midpoint of the first straight edge 220a in the second direction Y and extends along the first direction X. Preferably, when the first straight edge 220a is arranged in the first light-transmitting hole 221, the first sub-edge 231 is arranged symmetrically about the first midpoint P1, or when the first straight edge 220a is arranged in the second light-transmitting hole 222, the second sub-edge 232 is arranged symmetrically about the first midpoint P1.

[0052] Preferably, when the light-transmitting hole 220 has a first side edge 230, the first side edge 230 is located on a side of the light-transmitting hole 220 facing the first isolation opening 211. The distribution area of ​​the first isolation opening 211 is usually large, and by locating the first side edge 230 on a side of the light-transmitting hole 220 facing the first isolation opening 211, the positional interference between the light-transmitting hole 220 and the first isolation opening 211 can be improved.

[0054] The phrase "at least one light-transmitting hole 220 has at least two recesses 220d facing at least two isolation openings 210 located around it" means that at least one light-transmitting hole 220 has at least two recesses 220d, and at least two isolation openings 210 are provided around the light-transmitting hole 220, and the recesses 220d are provided corresponding to the isolation openings 210.

[0058] Preferably, the first side 230 has at least one of a straight line segment and a curved line segment, which allows the shape of the light-transmitting hole 220 to better match the shape of the plurality of isolation openings 210 located around it, and further increases the distribution area of ​​the light-transmitting holes 220, thereby improving light transmittance.

[0061] There are several ways to install the light emitting unit 400. Preferably, the light emitting unit 400 includes a first light emitting unit 401, a second light emitting unit 402, and a third light emitting unit 403, which are different in color.

The isolating opening 210 may further include a third isolating opening 213, and the third light emitting unit 403 may be disposed corresponding to the third isolating opening 213.

[0062] In some preferred embodiments, as shown in FIG. 2, the orthogonal projection of the metal structure 110 on the substrate 120 is located outside the orthogonal projection of the first light-transmitting hole 221 and the second light-transmitting hole 222 on the substrate 120 .

[0063] In these preferred embodiments, the installation position of the metal structure 110 is completely misaligned with the first light-transmitting hole 221 and the second light-transmitting hole 222, which ensures the light transmittance of the areas where the first light-transmitting hole 221 and the second light-transmitting hole 222 are located and can improve the light transmittance of the display panel.

[0064] The metal structure 110 may comprise a conductive structure on the array substrate 100, for example, the metal structure 110 comprises at least one of a gate electrode G, a signal line, and a capacitor plate C. In this way, the installation position of at least one of the gate electrode G, the signal line, and the capacitor plate C is completely misaligned with the first light-transmitting hole 221 and the second light-transmitting hole 222, thereby ensuring the light transmittance of the area where the first light-transmitting hole 221 and the second light-transmitting hole 222 are located and improving the light transmittance of the display panel. The signal line may be at least one of a scanning signal line and a power signal line.

[0065] Preferably, as stated above, the display panel further comprises a driving circuit T comprising a metal oxide transistor and a low-temperature polysilicon transistor, the gate electrode G comprises a first gate electrode provided on the metal oxide transistor and a second gate electrode provided on the low-temperature polysilicon transistor, and the metal structure 110 comprises at least one of the first gate electrode and the second gate electrode.

[0066] In these preferred embodiments, the driving circuit T comprises different types of metal oxide transistors and low-temperature polysilicon transistors, the gate electrode G comprises first and second gate electrodes located in the different types of transistors, and the metal structure 110 comprises at least one of the first and second gate electrodes, so that the installation position of at least one of the first and second gate electrodes is completely misaligned with the first light-transmitting hole 221 and the second light-transmitting hole 222, thereby ensuring the light transmittance of the areas where the first light-transmitting hole 221 and the second light-transmitting hole 222 are located and improving the light transmittance of the display panel.

[0067] The metal oxide transistor may be an indium gallium zinc oxide transistor.

Preferably, the driving circuit T may further include a threshold compensation transistor, a reset transistor, a light-emitting control transistor, etc., so that the orthogonal projections of the gate electrodes of these different types of transistors on the substrate 120 are completely outside the orthogonal projections of the first light-transmitting hole 221 and the second light-transmitting hole 222 on the substrate 120, thereby further improving the light transmittance of the display panel.

[0068] Referring to the preceding sentence, the isolated openings 210 may further include third isolated openings 213, and the plurality of third isolated openings 213 are arranged at intervals along the first direction X to form a second opening group H2. As shown in Fig. 6, the light-transmitting holes 220 further include third light-transmitting holes 223 located between at least two adjacent third isolated openings 213. By providing the additional third light-transmitting holes 223 located between two adjacent third isolated openings 213 in the second opening group H2, the total distribution area of ​​the light-transmitting holes 220 can be further increased, and the light transmittance of the display panel can be improved.

[0069] Preferably, the orthogonal projection area of ​​the first isolated opening 211 on the array substrate 100 is larger than the orthogonal projection area of ​​the second isolated opening 212 on the array substrate 100, and the orthogonal projection area of ​​the second isolated opening 212 on the array substrate 100 is larger than the orthogonal projection area of ​​the third isolated opening 213 on the array substrate 100. That is, the distribution area of ​​the third isolated opening 213 for accommodating the blue light emitting units 400 is maximized, which increases the distribution area of ​​the blue light emitting units 400 and improves the service life of the blue light emitting units 400.

[0070] Preferably, two second isolated openings 212 and two first isolated openings 211 are provided around the periphery of the third isolated opening 213, and the two first isolated openings 211 and the two second isolated openings 212 are alternately arranged around the periphery of the third isolated opening 213. Thus, two second light-emitting units 400 and two first light-emitting units 400 are provided around the periphery of the third light-emitting unit 400, and the two first light-emitting units 400 and the two second light-emitting units 400 are alternately arranged around the periphery of the third light-emitting unit 400, thereby reducing the spacing between the third light-emitting unit 400 and the first light-emitting unit 400 and the second light-emitting unit 400, and improving the display effect of the display panel.

[0071] Preferably, the orthogonal projection area of ​​the third light-transmitting hole 223 on the array substrate 100 is smaller than the orthogonal projection area of ​​the first light-transmitting hole 221 or the second light-transmitting hole 222 on the array substrate 100, so that the shape and dimensions of the third light-transmitting hole 223 are more compatible with the third isolation opening 213.

[0072] In some preferred embodiments, the first opening group H1 and the second opening group H2 are alternately arranged and offset in the second direction Y, so that the first isolated opening 211 is located between two adjacent third isolated openings 213 in the first direction X, and at least one third light-transmitting hole 223 is located on one side of the first isolated opening 211 or the second isolated opening 212 in the second direction Y.

[0073] In these preferred embodiments, the first aperture group H1 and the second aperture group H2 are alternately arranged along the second direction Y, so that the first isolated aperture 211 can be positioned correspondingly between two adjacent third isolated apertures 213, and the third light-transmitting aperture 223 positioned between two adjacent third isolated apertures 213 can be positioned on one side of the first isolated aperture 211 or the second isolated aperture 212 in the second direction Y, making the distribution of the isolated apertures 210 and the light-transmitting apertures 220 more scientific and reasonable, and the distribution of the multiple light-transmitting apertures 220 more uniform.

[0074] Preferably, at least one second isolation opening 212 is located corresponding to a position between two adjacent third isolation openings 213 along the first direction X, and at least one third light-transmitting hole 223 is located on one side of the second isolation opening 212 in the second direction Y.

[0075] In these preferred embodiments, the first light-transmitting hole 221, the second light-transmitting hole 222 and the third light-transmitting hole 223 are also provided around the second isolation opening 212, which can further increase the distribution area of ​​the light-transmitting holes 220 and make the distribution of the light-transmitting holes 220 more uniform.

[0076] Preferably, each third isolated opening 213 has a third light transmitting hole 223 on one side in the second direction Y, so as to further increase the distribution area of ​​the light transmitting holes 220. For example, one of the third isolated openings 213 has a third light transmitting hole 223 on one side in the second direction Y and no third light transmitting hole 223 on the other side in the third direction. In this way, of two adjacent third isolated openings 213 in two groups, a third light transmitting hole 223 is provided between the adjacent third isolated openings 213 in one group, and no third light transmitting hole 223 is provided between the adjacent third isolated openings 213 in the other group.

[0077] Preferably, of the two adjacent first and second isolation openings 211 and 212, the first isolation opening 211 has a third light-transmitting hole 223 on one side in the second direction Y, and the second isolation opening 212 has a third light-transmitting hole 223 on the other side in the second direction Y, so that the distribution of the third light-transmitting holes 223 is more even.

[0078] In some preferred embodiments, the second opening group H2 further includes a first gap Q and a second gap Q2 located between two adjacent third isolation openings 213, the first gap Q and the second gap Q2 being alternately arranged along the first direction X, and the third light-transmitting hole 223 being located in the first gap Q.

[0079] In these preferred embodiments, a third light-transmitting hole 223 is provided in the first gap Q, and no third light-transmitting hole 223 is provided in the second gap Q2, which can retract the position of the metal structure 110 and reduce the influence of ambient light on the metal structure 110 located corresponding to the second gap Q2.

[0080] Preferably, conductive wires are further provided on the substrate 120, and the wiring density of the conductive wires at the position where the first gap Q is located is lower than the wiring density of the conductive wires in the region where the second gap Q2 is located. By providing the third light transmitting hole 223 in the first gap Q, where the wiring density is relatively low, the influence of ambient light on the conductive wires can be reduced while increasing light transmittance.

[0081] 6, the orthogonal projection of at least one conductive wire on the substrate 120 and the orthogonal projection of the third light-transmitting hole 223 on the substrate 120 at least partially overlap each other. That is, the third light-transmitting hole 223 may be provided with a corresponding conductive wire, for example, the conductive wire passes through the third light-transmitting hole 223, thereby improving the light transmittance and simplifying the installation method of the third light-transmitting hole 223.

[0082] Preferably, the conductive wire comprises a power signal line, and the orthogonal projection of the power signal line on the substrate 120 at least partially overlaps with the orthogonal projection of the third light-transmitting hole 223 on the substrate 120. Preferably, the power signal line includes at least one of a driving power supply voltage signal line VDD and a voltage reference signal line.

[0083] The orthogonal projection of the third light transmitting hole 223 on the array substrate 100 may be formed in a variety of shapes, for example, a polygonal, circular, elliptical, etc.

[0084] Preferably, the shape of the third light-transmitting hole 223 and the shapes of the third isolation openings 213 located on both sides thereof are matched to each other, as shown in Figures 6 to 8. For example, in some preferred embodiments, the third light-transmitting hole 223 has a third side edge 250 facing the third isolation opening 213, and the third isolation opening 213 has a fourth side edge 260 facing the third side edge 250, and the third side edge 250 and the fourth side edge 260 are equally spaced apart.

[0085] The fact that the third side edge 250 and the fourth side edge 260 are equally spaced does not mean that they are strictly equal in the mathematical geometric sense, but rather that the third side edge 250 and the fourth side edge 260 are equally spaced within the range of process manufacturing error.

[0086] In these preferred embodiments, the third side edge 250 and the fourth side edge 260 are equally spaced apart, which allows the shape of the third light-transmitting holes 223 to be more compatible with the shape of the third isolating openings 213, maximizes the distribution area of ​​the third light-transmitting holes 223, and improves the light transmittance of the display panel. Furthermore, the third side edge 250 and the fourth side edge 260 are equally spaced apart, which ensures that the third light-transmitting holes 223 have a sufficiently large distribution area, and can reduce the mutual interference and influence between the third light-transmitting holes 223 and the third isolating openings 213.

[0087] Preferably, the third side edge 250 and the fourth side edge 260 may have an arc shape.

[0088] Preferably, the third side edge 250 includes a fifth sub-edge 251 and a sixth sub-edge 252 located on both sides of the third light-transmitting hole 223 in the first direction X, the fourth side edge 260 includes a seventh sub-edge 261 facing the fifth sub-edge 251 and an eighth sub-edge 262 facing the sixth sub-edge 252, the seventh sub-edge 261 and the eighth sub-edge 262 being located at two adjacent third isolation openings 213, the fifth sub-edge 251 and the seventh sub-edge 261 being arranged at equal intervals, and the sixth sub-edge 252 and the eighth sub-edge 262 being arranged at equal intervals, Preferably, the third light transmitting hole 223 has a second median line P2 extending along the second direction Y, and the fifth sub-edge 251 and the sixth sub-edge 252 are arranged symmetrically with respect to the second median line P2.

[0089] In these preferred embodiments, the third light-transmitting hole 223 is more adapted to the shape of the third isolation openings 213 located on either side thereof because the distances of the edges of the third isolation openings 213 located on either side thereof to the edges of the third isolation openings 213 are all equal.

[0090] Preferably, the third light transmitting hole 223 has a second midpoint line P2 extending along the second direction Y, and the fifth sub-edge 251 and the sixth sub-edge 252 are arranged symmetrically about the second midpoint line P2. Preferably, the second midpoint line P2 passes through the center of the third light transmitting hole 223 in the first direction X and extends along the second direction Y. Because the fifth sub-edge 251 and the sixth sub-edge 252 are symmetrical about the second midpoint line P2, the shape of the third light transmitting hole 223 can be simplified, and the third light transmitting hole 223 can be easily manufactured and molded.

[0091] In some preferred embodiments, the third light-transmitting hole 223 includes a first segment 223a and a second segment 223b having a third side edge 250, which are sequentially distributed along the second direction Y, and the width of the first segment 223a in the first direction X is greater than or equal to the width of the second segment 223b in the first direction X.

[0092] In these preferred embodiments, the third light-transmitting hole 223 is set into first segments 223a and second segments 223b of different widths so that the shape of the third light-transmitting hole 223 is more compatible with the shape of the gap between two adjacent third isolation openings 213, thereby making it possible to appropriately increase the distribution area of ​​the third light-transmitting hole 223.

[0093] For example, the two third isolation openings 213 located on both sides of the third light transmitting hole 223 in the first direction X have an elliptical shape, and are inclined toward each other in the direction from the first segment 223a to the second segment 223b, so that the gap width at the position where the first segment 223a is located is larger than the gap width at the position where the second segment 223b is located, and therefore, by setting the width of the first segment 223a to be relatively large, the distribution area of ​​the third light transmitting holes 223 can be appropriately increased and mutual influence between the third light transmitting holes 223 and the third isolation openings 213 is unlikely to occur. For example, when the third isolation opening 213 is in an elliptical shape and the two third isolation openings 213 are inclined toward each other, it can be understood that the lines on which the major axes of the two third isolation openings 213 are located intersect.

[0094] Preferably, the first segment 223a is rectangular and has an equal width in the second direction Y, thereby simplifying the shape of the first segment 223a, simplifying the shape of the third light-transmitting hole 223, and facilitating the manufacturing and molding of the third light-transmitting hole 223.

[0095] It is preferable that the width of the second segment 223b in the first direction X gradually decreases along the direction away from the first segment 223a, so that the shape of the second segment 223b can better fit the shape of the gap where it is located.

[0096] Preferably, in order to simplify the shape of the second segment 223b, simplify the shape of the third light-transmitting hole 223, and facilitate the manufacturing and molding of the third light-transmitting hole 223, the second segment 223b has a fourth straight edge 223b1, which is connected between the fifth sub-edge 251 and the sixth sub-edge 252, the second midpoint P2 passes through the midpoint of the fourth straight edge 223b1 in the first direction X, and the fourth straight edge 223b1 extends linearly along the first direction X.

[0097] In some preferred embodiments, the distance from the first isolation opening 211 to the first light-transmitting hole 221 and the first and second isolation openings 211 and 212 located on either side of the first isolation opening 221 is not equal to the distance from the second isolation opening 212 to the first light-transmitting hole 221. That is, the first isolation opening 211 and the second isolation opening 212 are not arranged symmetrically with respect to the first light-transmitting hole 221. Therefore, the first light-transmitting hole 221 can be arranged in an area where the density of the metal structure 110 is relatively low, thereby ensuring light transmittance.

[0098] In some preferred embodiments, the distance from the first isolation opening 211 to the second light-transmitting hole 222 and the first and second isolation openings 211 and 212 located on either side of the second light-transmitting hole 222 is not equal to the distance from the second isolation opening 212 to the second light-transmitting hole 222. That is, the first isolation opening 211 and the second isolation opening 212 are not arranged symmetrically with respect to the second light-transmitting hole 222, so that the second light-transmitting hole 222 can be arranged in an area where the density of the metal structure 110 is relatively low, thereby ensuring light transmittance.

[0099] In some preferred embodiments, in the first isolation opening 211 and the first and second light transmitting holes 221 and 222 located on either side thereof, the distance from the first light transmitting hole 221 to the first isolation opening 211 and the distance from the second light transmitting hole 222 to the first isolation opening 211 are not equal. That is, the first and second light transmitting holes 221 and 222 are not arranged symmetrically with respect to the first isolation opening 211. Therefore, the first and second light transmitting holes 221 and 222 are arranged in areas where the density of the metal structure 110 is relatively low, thereby ensuring light transmittance.

[0100] In some preferred embodiments, in the second isolation opening 212 and the first and second light transmitting holes 221 and 222 located on either side thereof, the distance from the first light transmitting hole 221 to the second isolation opening 212 and the distance from the second light transmitting hole 222 to the second isolation opening 212 are not equal. That is, the first and second light transmitting holes 221 and 222 are not arranged symmetrically with respect to the second isolation opening 212. Therefore, the first and second light transmitting holes 221 and 222 are arranged in areas where the density of the metal structure 110 is relatively low, thereby ensuring light transmittance.

[0101] In some preferred embodiments, the orthogonal projection area of ​​the first light transmitting hole 220 on the substrate 120 is larger than the orthogonal projection area of ​​the second light transmitting hole 220 on the substrate 120. Providing the first light transmitting hole 221 and the second light transmitting hole 222 with different areas allows each light transmitting hole 220 to better fit gaps of different sizes, and further increases the overall distribution area of ​​the light transmitting holes 220.

[0102] In some other preferred embodiments, the first light-transmitting hole 221 and the second light-transmitting hole 222 are located on both sides of the same isolation opening 210 in the first direction X, so that the first light-transmitting hole 221 and the second light-transmitting hole 222 are spaced apart along the first direction X, which can simplify the arrangement structure of the light-transmitting holes 220.

[0103] 2 and 7, the first light transmitting hole 221 and the second light transmitting hole 222 preferably have the same length in the second direction Y. This simplifies the shapes of the first light transmitting hole 221 and the second light transmitting hole 222 and facilitates manufacturing and molding of the first light transmitting hole 221 and the second light transmitting hole 222. For example, the length of the first light transmitting hole 221 in the second direction Y is b1, and the length of the second light transmitting hole 222 in the second direction Y is b2, where b1 and b2 are equal.

[0104] Preferably, the width of at least some of the first light transmitting holes 221 in the first direction X is larger than the width of the second light transmitting holes 222 in the first direction X. This allows the distribution areas of the first light transmitting holes 221 and the second light transmitting holes 222 to be different, and the shapes of the first light transmitting holes 221 and the second light transmitting holes 222 to be more compatible with the distribution pattern of the metal structures 110 in the array substrate 100. For example, the minimum width of the first light transmitting holes 221 in the first direction X is W1, and the minimum width of the second light transmitting holes 222 in the first direction X is W2, where W1 is larger than W2.

[0105] There are various ways to set the shapes of the first light transmitting hole 221 and the second light transmitting hole 222. For example, the shapes of the first light transmitting hole 221 and the second light transmitting hole 222 may be polygonal, circular, elliptical, etc., and the first light transmitting hole 221 and the second light transmitting hole 222 may also be irregular.

[0106] As mentioned above, as shown in FIG. 3, the display panel further includes a first sealing layer 500, which includes sealing portions 510 spaced apart from each other and sealing each isolation opening 210, and a positional retraction gap is formed between adjacent sealing portions 510, and the orthogonal projection of the positional retraction gap on the substrate 120 and the orthogonal projection of the light-transmitting hole 220 on the substrate 120 at least partially overlap.

[0107] The sealing portion 510 is used to seal the isolation opening 210, i.e., to seal at least a portion of the light emitting units 400 located in the isolation opening 210. The sealing portion 510 may extend from the isolation opening 210 to a side of the isolation structure 200 that is away from the substrate.

[0108] In these preferred embodiments, the orthogonal projection of the positional retraction gap on the substrate 120 and the orthogonal projection of the light-transmitting hole 220 on the substrate 120 at least partially overlap, i.e., the light-transmitting hole 220 and the sealing portion 510 are at least partially misaligned, thereby increasing the light transmittance of the area where the light-transmitting hole 220 is located.

[0109] Preferably, the orthogonal projection of the light-transmitting hole 220 on the substrate 120 is located within the orthogonal projection of the position retraction gap on the substrate 120, i.e., the light-transmitting hole 220 and the sealing portion 510 are completely misaligned, thereby further increasing the light transmittance of the area where the light-transmitting hole 220 is located.

[0110] Preferably, the material of the first sealing layer 500 can protect the inorganic material, so that the first sealing layer 500 has good density.

[0111] Preferably, as shown in FIG. 4, the sealing layer further includes a second sealing layer 600 located on the side of the first sealing layer 500 that is farther away from the array substrate 100, and the material of the second sealing layer 600 may include an organic material.

[0112] Preferably, the sealing layer further includes a third sealing layer 700 located on the side of the second sealing layer 600 that is away from the array substrate 100, and the material of the third sealing layer 700 may be the same as the material of the first sealing layer 500, for example, the material of the third sealing layer 700 is an inorganic material.

[0113] Preferably, when the pixel defining layer 300 includes a pixel defining portion 310 and a pixel opening 320 communicating with the isolation opening 210, the orthogonal projection of the light-transmitting hole 220 on the substrate 120 is located within the orthogonal projection of the pixel defining portion 310 on the substrate 120. That is, no through-hole is provided in the pixel defining portion 310 corresponding to the light-transmitting hole 220, which simplifies the installation method of the pixel defining portion 310.

[0114] Preferably, the pixel limiting portion 310 and the second sealing layer 600 are in contact with each other and connected within the light transmitting hole 220. This solves the problem that the sealing layer is easily peeled off.

[0115] Preferably, the display panel further includes a planarizing layer and a buffer layer sequentially disposed on the side of the defining layer facing the substrate 120, and the orthogonal projection of the light-transmitting hole 220 on the substrate 120 is located within the orthogonal projection of at least one of the buffer layer and the planarizing layer on the substrate 120. No holes are formed in the buffer layer and the planarizing layer in the area where the light-transmitting hole 220 is located, so that the buffer layer and the planarizing layer can provide better support for film layers such as the isolation structure 200.

[0116] There are various arrangement methods for the light emitting units 400, for example, the light emitting units 400 are arranged in an array along the first direction X and the second direction Y within the display area of ​​the display panel. The isolation openings 210 are distributed in an array along the first direction X and the second direction Y. The first light transmitting holes 221 and the second light transmitting holes 222 may be located around the isolation openings 210, for example, the first light transmitting holes 221 are located on one side of the isolation structure 200 in the first direction X, and the second light transmitting holes 222 are located on one side of the isolation openings 210 in the second direction Y.

[0117] In some preferred embodiments, the minimum spacing between the light-transmitting holes 220 and the isolating openings 210 is 3 μm to 4 μm, i.e., the minimum spacing between the orthogonally projected edges of the light-transmitting holes 220 on the array substrate 100 and the orthogonally projected edges of the isolated openings 210 on the array substrate 100 is 3 μm to 4 μm, thereby improving the problem of a too large spacing between the light-transmitting holes 220 and the isolated openings 210 affecting the distribution area of ​​the light-transmitting holes 220 and the light transmittance of the display panel, and also improving the problem of a too small spacing between the light-transmitting holes 220 and the isolated openings 210 increasing process difficulty and causing mutual influence between the light-transmitting holes 220 and the isolated openings 210.

[0118] Preferably, the minimum gap between the first light transmitting hole 221 and any one of the first isolated opening 211, the second isolated opening 212, and the third isolated opening 213 is 3 μm to 4 μm. The minimum gap between the second light transmitting hole 222 and any one of the first isolated opening 211, the second isolated opening 212, and the third isolated opening 213 is 3 μm to 4 μm. The minimum gap between the third light transmitting hole 223 and any one of the first isolated opening 211, the second isolated opening 212, and the third isolated opening 213 is 3 μm to 4 μm.

[0119] In any one of the above embodiments, the display panel comprises a display area, the display area comprising a main display area AA2 and a light-transmitting display area AA1, and the light-transmitting hole 220 is located in the light-transmitting display area AA1, thereby increasing the light transmittance of the light-transmitting display area AA1 and facilitating under-display integration of the light-sensing module in the light-transmitting display area AA1.

[0120] As shown in FIGS. 1 to 9 , a first aspect of the present application further provides a display panel including an array substrate 11 and an isolation structure 200, wherein the array substrate 11 includes a substrate 120 and a metal structure 110 disposed on the substrate 120, and the isolation structure 200 is disposed on one side of the array substrate 11, surrounding and closing the isolation opening 210 and the light-transmitting hole 220, and the orthogonal projection of the light-transmitting hole 220 on the substrate 120 and the orthogonal projection of the metal structure 110 on the substrate 120 are different from each other. , are at least partially offset from each other, and the isolation opening 210 is used to accommodate at least some of the light-emitting units 400, of which the light-transmitting holes 220 include a first light-transmitting hole 221 and a second light-transmitting hole 222, and the first light-transmitting hole 221 and the second light-transmitting hole 222 are located on the circumferential side of the same isolation opening 210, and the shape of the first light-transmitting hole 221 when orthogonally projected onto the substrate 120 is different from the shape of the second light-transmitting hole 222 when orthogonally projected onto the substrate 120.

[0121] In the embodiment of the present application, by providing the first light-transmitting holes 221 and the second light-transmitting holes 222 with different shapes, it is possible to make the different light-transmitting holes 220 adapt to the area in which they are located, and to make the overall distribution area of ​​the light-transmitting holes 220 as large as possible, thereby increasing the light transmittance.

[0122] The display panel of the present embodiment and the display panel of any one of the above embodiments can be referred to each other, and the same structures between the display panel of the present embodiment and the display panel of any one of the above embodiments will not be described again here. For example, the display panel of the present embodiment may have structures such as the recessed portion 220d and the protruding portion 210a.

[0123] 1 to 9 , a first aspect of the present application further provides a display panel including an array substrate 11, an isolation structure 200, and a light-emitting unit 400. The array substrate 11 includes a substrate 120 and a first active layer 130 disposed on the substrate 120. The isolation structure 200 is disposed on one side of the array substrate 11 and surrounds and closes the array substrate 11 to form a plurality of isolated openings 210 and a plurality of light-transmitting holes 220. The orthogonal projection of the light-transmitting holes 220 on the substrate 120 is at least partially offset from the orthogonal projection of the first active layer 130 on the substrate 120. The light-emitting unit 400 is disposed corresponding to the isolated openings 210. The display panel 1 according to the present application includes the array substrate 11, the light-emitting unit 400, and the isolation structure 200. The light-emitting unit 400 is used to emit light to realize the display function of the display panel 1. The isolation structure 200 surrounds and closes the isolated openings 210 and the light-transmitting holes 220. The isolating openings 210 are used to expose the light emitting units 400 to realize light emission. The light-transmitting holes 220 are used to realize light transmission through the display panel 1 and increase the light transmittance of the display panel 1. The orthogonal projection of the light-transmitting holes 220 on the substrate 120 and the orthogonal projection of the first active layer 130 on the substrate 120 are at least partially offset from each other, thereby reducing the impact of natural light within the light-transmitting holes 220 on the first active layer 130 and improving the performance of the first active layer 130, thereby improving the usability of the display panel.

[0124] 3 and 8, the first active layer 130 preferably includes a first channel area 131, and the orthogonal projection of the light-transmitting hole 220 on the substrate 120 is offset from the orthogonal projection of the first channel area 131 on the substrate 120. That is, the first channel area 131 and the light-transmitting hole 220 are offset from each other, thereby reducing or even eliminating the amount of light entering the first channel area 131 from the light-transmitting hole 220, improving the influence of photocarriers on the first channel area 131, and enhancing the performance of the first channel area 131, thereby improving the usability of the display panel.

[0125] There are various ways to form the material of the first active layer 130. Preferably, the material of the first active layer 130 comprises a metal oxide semiconductor material, such as an indium gallium zinc oxide semiconductor material. Preferably, as mentioned above, when the driving circuit T comprises a metal oxide transistor and a low-temperature polysilicon transistor, at least a portion of the first active layer 130 may be the semiconductor part of the metal oxide transistor.

[0126] 3 and 8, in some preferred embodiments, the display panel further includes a second active layer 140, and the orthogonal projection of the second active layer 140 on the substrate 120 is at least partially offset from the orthogonal projection of the light-transmitting holes 220 on the substrate 120. This can improve the influence of natural light in the light-transmitting holes 220 on the second active layer 140, enhance the performance of the second active layer 140, and improve the usability of the display panel.

[0127] 3, the second active layer 140 preferably includes a second channel area 141, and the orthogonal projection of the second channel area 141 on the substrate 120 is at least partially offset from the orthogonal projection of the light-transmitting hole 220 on the substrate 120. That is, the second channel area 141 and the light-transmitting hole 220 are offset from each other, thereby reducing or even eliminating the amount of light entering the second channel area 141 from the light-transmitting hole 220, improving the influence of photocarriers on the second channel area 141, and enhancing the performance of the second channel area 141, thereby improving the usability of the display panel.

[0128] 8, a light-shielding layer 150 is provided between the second channel area 141 and the isolation structure 200, and the orthogonal projection of the second channel area 141 on the substrate is located within the orthogonal projection of the light-shielding layer 150 on the substrate. The presence of the light-shielding layer 150 reduces or even eliminates the amount of light entering the second channel area 141 through the light-transmitting holes 220, thereby improving the influence of photocarriers on the second channel area 141 and enhancing the performance of the second channel area 141, thereby improving the usability of the display panel.

[0129] The light-shielding layer 150 may be disposed in a variety of positions, and may be disposed in the same layer as the capacitor plates, gate electrodes, signal lines, etc. Preferably, the material of the light-shielding layer 150 may include a metal light-shielding material, so that the light-shielding layer 150 has good light-shielding performance.

[0130] Preferably, the material of the second active layer 140 includes a low-temperature polysilicon semiconductor material. When the driving circuit T includes a metal oxide transistor and a low-temperature polysilicon transistor, at least a part of the second active layer 140 may be a semiconductor part of the low-temperature polysilicon transistor.

[0131] Preferably, the first active layer 130 and the second active layer 140 are provided on different layers and can be fabricated using different materials.

[0132] Preferably, the first active layer 130 is located on the side of the second active layer 140 that is farther from the substrate 120. This allows the second active layer 140 to be manufactured before the first active layer 130, thereby reducing the influence of the second active layer 140 on the first active layer 130 during its manufacture.

[0133] Preferably, the display panel of the embodiment of the present application and the display panel of any one of the above embodiments can be referenced to each other, and the same structural features in the display panel of the embodiment of the present application and the display panel of any one of the above embodiments will not be described repeatedly here.

[0134] As shown in FIGS. 10 to 16, the first aspect of the present application further provides a display panel including an array substrate 11, a light-emitting layer 40, and an isolation structure 200. The light-emitting layer 40 is located on one side of the array substrate 11 and comprises a plurality of light-emitting units 400, at least some of the isolation structures 200 surrounding and enclosing them to form isolation openings 210 and light-transmitting holes 220, the isolation openings 210 are used to expose the light-emitting units 400, and the light-transmitting holes 220 are formed between at least some adjacent isolation openings 210, wherein the isolation structures 200 comprise first equal-width segments 153 surrounding the light-transmitting holes 220, and the orthogonal projection of at least the first equal-width segments 153 on the array substrate 11 is located between the orthogonal projection of the light-transmitting holes 220 on the array substrate 11 and the orthogonal projection of the isolated openings 210 on the array substrate 11, and the first equal-width segments 153 have an equal width and a width direction extending from one to the other of the orthogonal projection of the light-transmitting holes 220 on the array substrate 11 and the orthogonal projection of the isolated openings 210 on the array substrate 11.

[0135] Preferably, the array substrate 11 and the substrate in the priority application having application number 202410382548.0 may have the same structure as the display panel, and the isolating opening 210 and the opening in the priority application having application number 202410382548.0 may have the same structure as the display panel.

[0136] The display panel 1 according to the present application includes an array substrate 11, a light-emitting layer 40, and an isolation structure 200. The light-emitting layer 40 includes a plurality of light-emitting units 400 that emit light to realize the display function of the display panel 1. The isolation structure 200 is enclosed to form isolated openings 210 and light-transmitting holes 220. The isolated openings 210 are used to expose the light-emitting units 400 for light emission. The light-transmitting holes 220 are located between at least some of the adjacent isolated openings 210, i.e., the orthogonal projections on the array substrate 11 are located between the orthogonal projections of at least some of the light-emitting units 400 on the array substrate 11, thereby realizing light transmission in the regions between the adjacent light-emitting units 400 and improving the light transmittance of the display panel 1. The isolation structure 200 has a first equal-width segment 153 surrounding the light-transmitting hole 220. The first equal-width segment 153 is located between the light-transmitting hole 220 and the isolation opening 210 and has an equal width. That is, the part of the isolation structure 200 between the light-transmitting hole 220 and the isolation opening 210 has an equal width. This ensures that the area of ​​the isolation opening 210 is constant, and on the premise of ensuring manufacturing yield, maximizes the area of ​​the light-transmitting hole 220, increases the distribution area of ​​the light-transmitting hole 220, and improves the light transmittance of the display panel 1.

[0137] Preferably, the opening shape of the light-transmitting hole 220 is reasonably set, for example, so that the shape of the light-transmitting hole 220 matches the shape of the isolation opening 210, and so that the light-transmitting hole 220 has an irregular shape, which allows the first equal-width segment 153 to be set with an equal width, and thereby maximizes the area of ​​the light-transmitting hole 220.

[0138] Furthermore, by providing the first equal-width segments 153 with equal widths so that the amount of reflection of light at different positions on the first equal-width segments 153 is approximately the same, the display effect of the display panel 1 can be improved. The width direction of the first equal-width segments 153 is the direction from one of the orthogonal projections of the light-transmitting holes 220 on the array substrate 11 and the orthogonal projections of the isolated openings 210 on the array substrate 11 located on both sides of the first equal-width segments 153 to the other. For example, the width direction of the first equal-width segments 153 may be the direction from the geometric center of the orthogonal projection on one array substrate 11 to the geometric center of the orthogonal projection on the array substrate 11 of the light-transmitting holes 220 on the array substrate 11 and the isolated openings 210 on the array substrate 11 located on both sides of the first equal-width segments 153.

[0139] In the above embodiment, as shown in FIG. 10 , the display panel 1 may be a transparent display panel, or may include a first display area AA1 and a second display area AA2. The light-transmitting holes 220 are provided in the first display area AA1, so that the light transmittance of the first display area AA1 is greater than that of the second display area AA2. Preferably, the first equal-width segments 153 are provided in the first display area AA1 to increase the distribution area of ​​the light-transmitting holes 220. A light-sensing module, such as a camera module or a fingerprint recognition module, may be provided below the first display area AA1. The light transmittance of the first display area AA1 is relatively high, which can improve the performance of the light-sensing module and thereby the performance of the display panel 1.

[0140] In some preferred embodiments, as shown in Figures 10 to 14, the isolation structure 200 comprises a first sublayer 201 and a second sublayer 202, the first sublayer 201 being located on the side of the second sublayer 202 facing the array substrate 11, and the orthogonal projection on the array substrate 11 being located within the orthogonal projection of the second sublayer 202 on the array substrate 11.

[0141] In these preferred embodiments, the isolation structure 200 includes a first sub-layer 201 and a second sub-layer 202, the second sub-layer 202 being located on the side of the first sub-layer 201 that faces away from the array substrate 11, and the orthogonal projection of the first sub-layer 201 on the array substrate 11 being located within the orthogonal projection of the second sub-layer 202 on the array substrate 11, i.e., the orthogonal projection area of ​​the first sub-layer 201 is smaller than the orthogonal projection area of ​​the second sub-layer 202, thereby forming a recess under the second sub-layer 202. During subsequent manufacturing of the light-emitting units 400, the light-emitting material can be separated at the edge of the second sub-layer 202 to form independent light-emitting units 400, which eliminates the need for precision mask manufacturing processes and simplifies the manufacturing process of the display panel 1.

[0142] When the isolation structure 200 includes a first sublayer 201 and a second sublayer 202, the first equal-width segment 153 may be provided in the first sublayer 201 or the second sublayer 202. Preferably, the first equal-width segment 153 may be provided in the second sublayer 202, for example, the first equal-width segment 153 includes a second subsegment 202a provided in the second sublayer 202.

[0143] In these preferred embodiments, the dimensions of the second sublayer 202 are relatively large, and the shape and dimensions of the light-transmitting holes 220 are determined by the shape and dimensions of the second sublayer 202. Therefore, by providing the second subsegments in the second sublayer 202, it is possible to ensure that the dimensions of the light-transmitting holes 220 are set sufficiently large, and the distribution area of ​​the light-transmitting holes 220 can be increased.

[0144] Preferably, the first equal-width segment 153 further includes a first sub-segment 201a provided in the first sub-layer 201. That is, equal-width segments are also provided in the first sub-layer 201, so that the shape of the first sub-layer 201 and the shape of the second sub-layer 202 are more compatible with each other, and the performance of the isolation structure 200 is ensured.

[0145] In one possible embodiment, the width D of the first equal-width segments 153 is 1 μm to 4 μm along a direction parallel to the plane of the array substrate 11. For example, the width D of the first equal-width segments 153 may be 1 μm, 1.1 μm, 1.5 μm, 1.8 μm, 2 μm, 2.3 μm, 2.7 μm, 2.9 μm, 3 μm, 3.2 μm, 4 μm, etc., i.e., the width D of the first equal-width segments 153 when orthogonally projected on the array substrate 11 is 1 μm to 4 μm. This can be improved by avoiding a situation where the width of the first equal-width segments 153 is too small, which increases the manufacturing process difficulty and affects the manufacturing of the display panel 1. It can also be improved by avoiding a situation where the width of the first equal-width segments 153 is too large, which affects the distribution area of ​​the light-transmitting holes 220 and therefore the light transmittance of the display panel 1.

[0146] Preferably, when the isolation structure 200 includes the first sub-layer 201 and the second sub-layer 202, the width of the first sub-segment 201a along the direction parallel to the plane of the array substrate 11 is a first preset dimension D1, which is 1 μm to 3 μm, for example, 1 μm, 1.1 μm, 1.5 μm, 1.8 μm, 2 μm, 2.3 μm, 2.7 μm, 2.9 μm, 3 μm, etc.

[0147] Preferably, the width of the second sub-segment 202a along the direction parallel to the plane of the array substrate 11 is a second preset dimension D2, which is 2 μm to 4 μm, for example, 2 μm, 2.3 μm, 2.7 μm, 2.9 μm, 3 μm, 3.2 μm, 4 μm, etc.

[0148] In these preferred embodiments, the width dimension of the first subsegment 201a is relatively small and the width dimension of the second subsegment 202a is relatively large, ensuring that the orthogonal projection of the first sublayer 201 on the array substrate 11 is located within the orthogonal projection of the second sublayer 202 on the array substrate 11, while allowing the width of the second subsegment 202a to be as small as possible to ensure the distribution area of ​​the light-transmitting holes 220.

[0149] There are various ways to install the light emitting units 400. For example, the light emitting units 400 include a first electrode 410, a light emitting functional layer 420, and second electrodes 430 and 430, which are stacked in a direction away from the array substrate 11. The material of the isolation structure 200 may include a conductive material, so that the second electrode 430 can be electrically connected to the isolation structure 200, and the isolation structure 200 can realize the arrangement of the second electrodes 430 of the multiple light emitting units 400 over the entire surface.

[0150] For example, preferably, the material of the first sub-layer 201 includes a conductive material, and the first sub-layer 201 is electrically connected to the second electrode 430, so that the second electrodes 430 of the multiple light-emitting units 400 can be connected to each other by the first sub-layer 201 to form a plane electrode.

[0151] Preferably, the material of the second sub-layer 202 includes a conductive material, and the second sub-layer 202 is electrically connected to the second electrode 430, thereby increasing the distribution area of ​​the conductive material and reducing the voltage drop of the second electrode 430 at different positions in the display area AA.

[0152] In one possible embodiment, as shown in Figures 11 to 4, the isolation structure 200 further includes a second equal-width segment 154, which is located between adjacent isolation openings 210, has an equal width, and its width direction is from one to the other of the orthogonal projections of the two adjacent isolation openings 210 on the array substrate 11.

[0153] In these preferred embodiments, the isolation structure 200 further includes a second equal-width segment 154 located between two adjacent isolation openings 210, and the second equal-width segment 154 is provided with an equal width, so that the light reflection ability at different positions in the second equal-width segment 154 is approximately consistent, thereby improving the display effect of the display panel 1.

[0154] The width direction of the second equal-width segment 154 is the direction from one to the other of the orthogonal projections of the two isolated openings 210 located on both sides of the second equal-width segment 154 onto the array substrate 11. For example, the width direction of the second equal-width segment 154 is the direction from the geometric center of the orthogonal projection on one array substrate 11 to the geometric center of the orthogonal projection on the other array substrate 11 of the two isolated openings 210 located on both sides of the second equal-width segment 154.

[0155] There are several ways to set the widths of the first equal width segments 153 and the second equal width segments 154. For example, the minimum width d1 of the first equal width segments 153 and the minimum width d2 of the second equal width segments 154 may be equal, or d2≦2d1.

[0156] In these preferred embodiments, the width of the first equal-width segment 153 is smaller than or equal to the width of the second equal-width segment 154, ensuring that the light-transmitting hole 220 has a sufficient opening area and ensuring the light transmittance of the display panel 1.

[0157] Furthermore, to ensure that the light-transmitting hole 220 has a sufficiently large opening area, the width of the first equal-width segment 153 is typically set to the minimum width within the process tolerance. If the minimum width d1 of the first equal-width segment 153 and the minimum width d2 of the second equal-width segment 154 satisfy d2≦2d1, the second equal-width segment 154 is not suitable for forming the light-transmitting hole 220 due to limitations in the manufacturing process, so as to avoid adversely affecting the function of the isolation structure 200.

[0158] In one possible embodiment, the second equal width segment 154 comprises a first sub-area and a second sub-area spaced apart in a direction aligned along the width of the second equal width segment 154 .

[0159] There are several ways to install the relative positional relationship between the first sub-area and the second sub-area. For example, the first sub-area and the second sub-area are spaced apart and connected to each other by a connecting portion 1310, thereby further reducing the distribution area of ​​the isolation structure 200 and increasing the distribution area of ​​the light-transmitting holes 220.

[0160] Alternatively, the first sub-area and the second sub-area are formed integrally, and the sum of the minimum width of the orthogonal projection of the first sub-area on the array substrate 11 and the minimum width of the orthogonal projection of the second sub-area on the array substrate 11 is smaller than or equal to twice the minimum width d1 of the orthogonal projection of the first equal-width segment 153 on the array substrate 11, thereby ensuring that the first sub-area and the second sub-area formed integrally have a sufficiently small width, thereby reducing the impact on the light transmittance of the display panel 1.

[0161] In one possible embodiment, the minimum width of the connecting portion 1310 when orthogonally projected on the array substrate 11 is a third preset dimension D3, and the third preset dimension D3 and the minimum width d1 of the first equal-width segment 153 when orthogonally projected on the array substrate 11 satisfy D3=d1, so that the connecting portion 1310 has a sufficiently small width, which further reduces the distribution area of ​​the isolation structures 200 and increases the distribution area of ​​the light-transmitting holes 220, thereby improving the light transmittance of the display panel 1.

[0162] In one possible embodiment, the light emitting unit 400 comprises a first light emitting unit 401, a second light emitting unit 402, and a third light emitting unit 403 that are different in color.

[0163] Specifically, the first light-emitting unit 401 may be a blue light-emitting unit 400 , the second light-emitting unit 402 may be a red light-emitting unit 400 , and the third light-emitting unit 403 may be a green light-emitting unit 400 .

[0164] 13 and 14 , the isolated openings 210 include a first isolated opening 211 used to expose the first light-emitting unit 401, a second isolated opening 212 used to expose the second light-emitting unit 402, and a third isolated opening 213 used to expose the third light-emitting unit 403. The first isolated openings 211 and the second isolated openings 212 are alternately arranged along a second direction Y intersecting the first direction X to form a first opening row A1, and the third isolated openings 213 are arranged along the second direction Y to form a second opening row A2, and the first opening row A1 and the second opening row A2 are alternately arranged along the first direction X.

[0165] In the above embodiment, the third light-emitting unit 403 is arranged to surround the first light-emitting unit 401, the third light-emitting unit 403 is arranged to surround the second light-emitting unit 402, and the first light-emitting unit 401 and the second light-emitting unit 402 are arranged to surround the third light-emitting unit 403 alternately, thereby achieving a good light mixing effect and improving the light output quality of the display panel 1.

[0166] Preferably, a second equal width segment 154 is provided between the first isolation opening 211 and the third isolation opening 213, and / or a second equal width segment 154 is provided between the adjacent second isolation opening 212 and the adjacent third isolation opening 213.

[0167] In the above embodiment, the spacing between the first and third isolating openings 211 and 213 is too small to accommodate the light-transmitting holes 220, so the second equal-width segment 154 may be provided between the first and third isolating openings 211 and 213. Similarly, the spacing between the second and third isolating openings 212 and 213 is too small to accommodate the light-transmitting holes 220, so the second equal-width segment 154 may be provided between the second and third isolating openings 212 and 213.

[0168] For example, if the first light-emitting unit 401 is a blue light-emitting unit 400 and the second light-emitting unit 402 is a red light-emitting unit 400, the opening dimension of the second isolated opening 212 is smaller than the opening dimension of the first isolated opening 211, so the spacing distance between the first isolated opening 211 and the third isolated opening 213 is relatively small, and the spacing distance between the second isolated opening 212 and the third isolated opening 213 is relatively large, so the second equal-width segments 154 between the first isolated opening 211, the second isolated opening 212 and the third isolated opening 213 can be set using different installation methods.

[0169] For example, the second equal-width segment 154 includes a first sub-area and a second sub-area located between the adjacent first isolation opening 211 and third isolation opening 213, and the first sub-area and the second sub-area are spaced apart and connected by a connecting portion 1310. Since the first sub-area and the second sub-area are spaced apart, the distribution area of ​​the isolation structures 200 can be further reduced and the distribution area of ​​the light-transmitting holes 220 can be increased, thereby improving the light transmittance.

[0170] and / or the second equal-width segment 154 comprises a first sub-area and a second sub-area located between adjacent second isolation openings 212 and third isolation openings 213, the first sub-area and the second sub-area being integrally formed, and the sum of their minimum widths being less than or equal to 2d1, thereby ensuring that the integrally formed first sub-area and second sub-area have a sufficiently small width and reducing the impact thereof on the light transmittance of the display panel 1.

[0171] In the above embodiment, the third isolation opening 213 includes a first sub-opening 1324 and a second sub-opening 1325, the first sub-openings 1324 and the second sub-openings 1325 being alternately arranged along the first direction X, and the adjacent first sub-openings 1324 and the adjacent second sub-openings 1325 being symmetrically arranged along an axis of symmetry parallel to the second direction Y.

[0172] The above-described arrangement of the third isolating openings 213 can make the distribution of the third isolating openings 213 along the circumferential direction of the first isolating openings 211 more uniform, thereby improving the uniformity of the display panel 1.

[0173] At the same time, the above-mentioned installation method of the third isolation openings 213 can make the distribution uniformity of the third isolation openings 213 along the circumferential direction of the second isolation openings 212 relatively stronger, thereby further improving the uniformity of the display panel 1.

[0174] In one possible embodiment, as shown in FIG. 13, the first isolated opening 211 is located at two opposite vertices of the imaginary rectangle M1, and the second isolated opening 212 is located at the other two opposite vertices of the imaginary rectangle M1, and the orthogonal projection of the shortest side of the imaginary rectangle M1 on the array substrate 11 and the orthogonal projection of the light-transmitting hole 220 on the array substrate 11 do not overlap.

[0175] In the above embodiment, the distance between the adjacent first isolation opening 211 and second isolation opening 212 on the shortest side of the virtual rectangle M1 is small, which is not suitable for installing the light-transmitting hole 220 in order to ensure the yield of the isolation structure 200.

[0176] The first isolated openings 211 and the second isolated openings 212 are alternately arranged along the first direction X to form a first aperture row L1. In one possible embodiment, as shown in Figures 10 to 13, the light-transmitting holes 220 include first light-transmitting holes 221 located between the first isolated openings 211 and the second isolated openings 212 in the first aperture row L1, and second light-transmitting holes 222 located between at least some of the first isolated openings 211 and the second isolated openings 212 in the first aperture column A1. By providing the light-transmitting holes 220 in both the first aperture row L1 and the first aperture column A1, the distribution area of ​​the light-transmitting holes 220 can be increased, and the light transmittance of the display panel 1 can be further improved.

[0177] 15 and 16, the isolation structure 200 may be an auxiliary cathode. For example, the second electrode 430 is a plane electrode, the isolation structure 200 is located on the side of the second electrode 430 that is farther from the array substrate 11, an insulating layer 16 may be further provided between the isolation structure 200 and the second electrode 430, and the isolation structure 200 and the second electrode 430 are connected by a via.

[0178] The present application further provides another display panel 1, as shown in Figures 10 to 14, comprising an array substrate 11, an emissive layer 40 located on one side of the array substrate 11 and having a plurality of emissive units 400, and an isolation structure 200 that surrounds and closes at least a portion of the isolated openings 210 to expose the emissive units 400, and forms light-transmitting holes 220 between at least some of adjacent isolated openings 210, wherein the isolation structure 200 has second equal-width segments 154 surrounding the isolated openings 210, and the orthogonal projections of at least the second equal-width segments 154 on the array substrate 11 are located between the orthogonal projections of the adjacent isolated openings 210 on the array substrate 11, and the second equal-width segments 154 have an equal width and a width direction that faces from one to the other of the orthogonal projections of the two adjacent isolated openings 210 on the array substrate 11.

[0179] The display panel 1 according to the present application includes an array substrate 11, a light-emitting layer 40, and an isolation structure 20015. The light-emitting layer 40 includes a plurality of light-emitting units 400 that emit light to realize the display function of the display panel 1. The isolation structure 200 further includes second equal-width segments 154 located between two adjacent isolation openings 210, and the second equal-width segments 154 have equal widths, so that the light reflecting abilities of different positions on the second equal-width segments 154 are approximately consistent, thereby improving the display effect of the display panel 1.

[0180] In some preferred embodiments, the isolation structure 200 further includes a first equal-width segment 153 located between adjacent light-transmitting holes 220 and isolation openings 210, wherein the minimum width of the first equal-width segment 153 when orthogonally projected on the array substrate 11 is d1, and the minimum width of the second equal-width segment 154 when orthogonally projected on the array substrate 11 is d2, where d2≦2d1.

[0181] In these preferred embodiments, the width of the first equal-width segment 153 is smaller than or equal to the width of the second equal-width segment 154, thereby ensuring that the light-transmitting hole 220 has a sufficient opening area and ensuring the light transmittance of the display panel 1.

[0182] In addition, to ensure that the light-transmitting hole 220 has a sufficiently large opening area, the width of the first equal-width segment 153 is usually set to the minimum width within the process tolerance range, and if the minimum width d1 of the first equal-width segment 153 and the minimum width d2 of the second equal-width segment 154 satisfy d2≦2d1, the second equal-width segment 154 is not suitable for forming the light-transmitting hole 220, so as to avoid adversely affecting the function of the isolation structure 200 due to manufacturing process limitations.

[0183] In some preferred embodiments, the second equal-width segment 154 includes a first sub-area and a second sub-area spaced apart along a direction from one of two adjacent isolation openings 210 to the other, and the first sub-area and the second sub-area are spaced apart and connected to each other by a connecting portion 1310, thereby further reducing the distribution area of ​​the isolation structure 200 and increasing the distribution area of ​​the light-transmitting holes 220.

[0184] Alternatively, the first sub-area and the second sub-area are integrally formed, and the sum of the minimum widths of the first sub-area and the second sub-area when orthogonally projected onto the array substrate 11 is smaller than or equal to 2d1, thereby ensuring that the first sub-area and the second sub-area formed integrally have a sufficiently small width, thereby reducing the impact on the light transmittance of the display panel 1.

[0185] In some preferred embodiments, the second equal-width segment 154 includes a first sub-area and a second sub-area that are spaced apart, and the first sub-area and the second sub-area are spaced apart and connected by a connecting portion 1310, such that the minimum width d3 of the connecting portion 1310 when orthogonally projected onto the array substrate 11 and the minimum width d1 of the first equal-width segment 153 when orthogonally projected onto the array substrate 11 satisfy d3=d1. This allows the connecting portion 1310 to have a sufficiently small width, which further reduces the distribution area of ​​the isolation structures 200 and increases the distribution area of ​​the light-transmitting holes 220, thereby improving the light transmittance of the display panel 1.

[0186] In this embodiment, the installation manner of the light emitting unit 400 and the isolation structure 200 is as described above, and will not be described again here. The display panel 1 in this embodiment and the display panel 1 in any one of the above embodiments can be used as references for each other.

[0187] The present application further provides another display panel 1, as shown in FIGS. 10 to 14, having a first display area and a second display area surrounding at least a part of the first display area, the display panel 1 including an array substrate 11, a light-emitting layer 40 located on one side of the array substrate 11 and including a plurality of light-emitting units 400, and an isolation layer 210 at least partially surrounding and closing the first display area, the isolation layer 210 being used to expose the light-emitting units 400, and the light-transmitting holes 220 formed between at least a part of adjacent isolation openings 210. The isolation structure 200 comprises a first equal-width segment 153 surrounding a light-transmitting hole 220, and the orthogonal projection of at least the first equal-width segment 153 on the array substrate 11 is located between the orthogonal projection of an adjacent isolation opening 210 on the array substrate 11 and the orthogonal projection of the light-transmitting hole 220 on the array substrate 11, and the first equal-width segment 153 has an equal width, and its width direction is from one of the orthogonal projection of the light-transmitting hole 220 on the array substrate 11 to the other of the orthogonal projection of the isolation opening 210 on the array substrate 11.

[0188] In the embodiment of the present application, the light-transmitting holes 220 are provided in the first display area to increase the light transmittance of the first display area and realize under-display integration of the light-sensing module in the first display area. The first equal-width segments 153 are provided in the first display area, and the first equal-width segments 153 have equal widths, i.e., some of the isolation structures 200 between the light-transmitting holes 220 and the isolation openings 210 have equal widths. This ensures that the area of ​​the isolation openings 210 is constant, and on the premise of ensuring the manufacturing yield, the area of ​​the light-transmitting holes 220 can be maximized, the distribution area of ​​the light-transmitting holes 220 can be increased, and the light transmittance of the display panel 1 can be improved.

[0189] In this embodiment, the installation manner of the light emitting unit 400 and the isolation structure 200 is as described above, and will not be described again here. The display panel 1 in this embodiment and the display panel 1 in any one of the above embodiments can be used as references for each other.

[0190] The present application further provides a display device 2, as shown in FIG. 17, including the display panel 1 according to any one of the above embodiments of the present application.

[0191] The display device 2 of the present application further includes a light-sensing module, which is integrated within the display panel 1 or located on the side of the array substrate 11 away from the light-emitting layer 40, thereby increasing the light transmittance of the display panel 1 and enabling the light-sensing module to better receive light rays, thereby improving the production yield of the light-sensing module.

[0192] In the present embodiment, the display panel includes an array substrate 100 and an isolation structure 200 that encloses the isolation openings 210 and forms light-transmitting holes 220. The light-emitting units 400 are disposed within the isolation openings 210, thereby reducing crosstalk between adjacent light-emitting units 400 and realizing light-emitting display of the display panel. The array substrate 100 includes a substrate 120 and a metal structure 110 disposed on the substrate 120. The metal structure 110 can be used to drive the light-emitting units 400 to emit light. The light-transmitting holes 220 are used to improve the light transmittance of the display panel and facilitate under-display integration of a light-sensing module. The orthogonal projection of the light-transmitting holes 220 on the substrate 120 and the orthogonal projection of the metal structure 110 on the substrate 120 are at least partially misaligned, thereby improving the influence of the metal structure 110 on the light-transmitting holes 220. Generally, the distribution shapes of the metal structures 110 corresponding to the periphery of the same isolating opening 210 on the substrate are different, and the orthogonal projection shapes of the first light-transmitting holes 221 and the second light-transmitting holes 222 on the substrate are different, so that users can reasonably set the shapes of the first light-transmitting holes 221 and the second light-transmitting holes 222 based on the distribution of the metal structures 110 on the substrate so that their dimensions are more suitable for the distribution shapes of the metal structures 110 on the substrate, thereby increasing the distribution area of ​​the light-transmitting holes 220 as much as possible and alleviating the problem of signal interference caused by the metal structures 110 being exposed through the light-transmitting holes 220, thereby improving the performance of the display panel.

[0193] The display panel of the present embodiment and any one of the above embodiments can be referenced to each other. For example, the width of at least some of the first light transmitting holes 221 in the first direction X is larger than the width of the second light transmitting holes 222 in the first direction X, so that the dimensions of the first light transmitting holes 221 and the second light transmitting holes 222 are more compatible with the distribution shape of the metal structures 110 in the substrate.

[0194] Preferably, the extension lengths of the first light transmitting holes 221 and the second light transmitting holes 222 in the second direction Y are the same so as to simplify the distribution shape of the light transmitting holes 220 and facilitate the manufacturing and molding of the light transmitting holes 220.

[0195] Preferably, the light-transmitting hole 220 has the first side edge 230, and the isolation opening 210 has the second side edge 240. The manner of installing the first side edge 230 and the second side edge 240 is as described above, and will not be described again here. The light-transmitting hole 220 may further have the first straight edge 220a. As shown in FIGS. 1 to 17, an embodiment of a second aspect of the present application further provides a display device including the display panel 10 of any one of the embodiments of the first aspect. Since the display device according to the embodiment of the second aspect of the present application includes the display panel 10 of any one of the embodiments of the first aspect, it has the beneficial effects of the display panel 10 of any one of the embodiments of the first aspect, and will not be described again here.

[0196] The display device in the embodiments of the present application includes, but is not limited to, devices with display functions such as mobile phones, personal digital assistants (abbreviated as PDA), tablets, e-books, televisions, access control, smart landlines, and consoles.

[0197] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and equivalents may be substituted for the components therein without departing from the scope of the present application. In particular, unless there is a conflict of structure, any of the technical features of each paragraph mentioned in each embodiment may be combined in any manner.
