[0043] Figure 1 is a structural diagram of a display panel provided in an embodiment of the present application; Figure 2 See Figure 1 Schematic diagram of the local enlarged structure, Figure 3 In one example Figure 2 Cross-sectional view at AA in the middle.

[0044] like Figures 1 to 3 As shown, an embodiment of the present application provides a display panel, which includes 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. The isolation structure 200 encloses a plurality of isolation openings 210 and light-transmitting holes 220. The orthographic projection of the light-transmitting holes 220 on the substrate 120 and the orthographic projection of the metal structure 110 on the substrate 120 are at least partially offset. The light-emitting unit 400 is disposed corresponding to the isolation openings 210. The orthographic projection of the light-transmitting holes 220 on the substrate 120 includes a recessed portion 220d.

[0045] Optionally, the light-emitting unit 400 includes a first electrode 410, a light-emitting functional layer 420, and a second electrode 430 stacked in a direction away from the substrate 120. The light-emitting unit 400 and the isolation opening 210 are disposed correspondingly, which 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.

[0046] In an embodiment of the present application, the display panel includes an array substrate 100 and an isolation structure 200, and the isolation structure 200 encloses an isolation opening 210 and a light-transmitting hole 220. At least part of the light-emitting units 400 are arranged in the isolation opening 210 to improve the mutual crosstalk between adjacent light-emitting units 400 and realize the luminous display of the display panel. The array substrate 100 includes a substrate 120 and a metal structure 110 arranged on the substrate 120, and the metal structure 110 can be used to drive the light-emitting units 400 to emit light. The light-transmitting hole 220 is used to improve the transmittance of the display panel and facilitate the under-screen integration of the photosensitive module. The orthographic projection of the light-transmitting hole 220 on the substrate 120 and the orthographic projection of the metal structure 110 on the substrate 120 are at least partially staggered, which can improve the influence of the metal structure 110 on the transmittance of the light-transmitting hole 220. At least one light-transmitting hole 220 includes a recessed portion 220d, and the distance between the orthographic projection of the recessed portion 220d on the substrate 120 and the orthographic projection of the isolation opening 210 on the substrate 120 can be set to be relatively small, so as to maximize the distribution area of ​​the light-transmitting hole 220 and improve the signal interference problem caused by the exposure of more metal structures 110 through the light-transmitting hole 220, thereby improving the performance of the display panel.

[0047] Optionally, in at least one group of adjacent light-transmitting holes 220 and isolation openings 210, the center of one of them points to the center of the other as a preset direction, for example, the preset direction is Figure 2 In the X direction, the minimum distance between the edge of the recessed portion 220d and the edge of the isolation opening 210 in the preset direction is greater than or equal to the preset distance h. This allows the distance between the recessed portion 220d and the isolation opening 210 to be set to be smaller, thereby maximizing the distribution area of ​​the light-transmitting holes 220.

[0048] Optionally, along a predetermined direction, in at least one group of adjacent light-transmitting holes 220 and isolation openings 210, in an orthographic projection on the substrate 120, the isolation opening 210 includes a protrusion 210a corresponding to the recess 220d. This allows the shapes of the adjacent isolation openings 210 and light-transmitting holes 220 to be more closely matched, thereby maximizing the distribution area of ​​the light-transmitting holes 220.

[0049] Optionally, at least a portion of the protrusion 210a matches the shape of at least a portion of the recess 220d, so as to increase the distribution area of ​​the light-transmitting holes 220 as much as possible.

[0050] Optionally, the light-transmitting hole 220 includes 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 are located on the peripheral 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.

[0051] In these optional embodiments, the distribution areas of the metal structures 110 corresponding to the same isolation opening 210 in 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. This facilitates the user to reasonably set the sizes of the first light-transmitting hole 221 and the second light-transmitting hole 222 according to the distribution of the metal structures 110 in the substrate, so that the sizes of the first light-transmitting hole 221 and the second light-transmitting hole 222 are more adapted to the distribution pattern of the metal structures 110 in the substrate, thereby maximizing the distribution area of ​​the light-transmitting hole 220.

[0052] Optionally, a driving circuit is provided in the array substrate 100 and at least part of the metal structure 110 is used to form the driving circuit. Optionally, at least part of the light-transmitting holes 220 are projected outside the orthographic projection of the driving circuit T on the array substrate 100.

[0053] The orthographic projection of the light-transmitting hole 220 on the substrate 120 and the orthographic projection of the metal structure 110 on the substrate 120 are at least partially offset, which means that the orthographic projection of the same light-transmitting hole 220 on the substrate and the orthographic projection of the metal structure 110 on the substrate 120 are at least partially offset, and the metal structure 110 is not disposed in a corresponding area of ​​at least a portion of the same light-transmitting hole 220. Alternatively, the orthographic projection of the light-transmitting hole 220 on the substrate 120 may be located outside the orthographic projection of the metal structure 110 on the substrate 120, or the orthographic projection of a portion of the light-transmitting hole 220 on the substrate 120 and the orthographic projection of the metal structure 110 on the substrate 120 overlap, and the orthographic projection of another portion of the light-transmitting hole 220 on the substrate 120 is located outside the orthographic projection of the metal structure 110 on the substrate 120.

[0054] Optionally, the display panel further includes a pixel definition layer 300, which is disposed on the array substrate 100. The pixel definition layer 300 includes a pixel defining portion 310 and a pixel opening 320 provided in the pixel defining portion 310. The pixel opening 320 is connected to the isolation opening 210. The light-emitting unit 400 is disposed corresponding to the pixel opening, and a portion of the structure is located within the pixel opening 320. The isolation structure 200 can be disposed on the side of the pixel defining portion 310 facing away from the array substrate 100, or a clearance opening can be provided on the pixel defining portion 310, and the isolation structure 200 can be located within the clearance opening and directly contact and connect with the array substrate 100. Optionally, the material of the pixel definition layer 300 can be an inorganic material, so that the thickness of the pixel definition layer 300 can be appropriately reduced, thereby reducing the overall thickness of the display panel 10.

[0055] Optionally, the distance between at least a portion of the edge of the orthographic projection of the light-transmitting hole 220 on the array substrate 100 and at least a portion of the edge of the orthographic projection of the isolation opening 210 on the array substrate 100 is greater than or equal to a preset distance h. This can reduce the interaction between the isolation opening 210 and the light-transmitting hole 220.

[0056] There are various value ranges for the preset distance h of the light-transmitting hole 220. The preset distance h can be 3μm to 4μm. For example, the preset distance h is 3μm, 3.2μm, 3.5μm, 3.8μm, 4μm, etc., to improve the situation where the preset distance h is too large and affects the opening area of ​​the light-transmitting hole 220, or the preset distance h is too small and the light-transmitting hole 220 affects the position stability of the isolation opening 210. The preset distance h is not fixed in the actual process fluctuations, and the upper and lower errors are all within the protection range.

[0057] There are many ways to set up the isolation structure 200, such as Figure 3 As shown, the isolation structure 200 may include a first sublayer 201 and a second sublayer 202 stacked in a direction away from the array substrate 100, the orthographic projection of the first sublayer 201 on the array substrate 100 is located within the orthographic projection of the second sublayer 202 on the array substrate 100, that is, the second sublayer 202 is arranged to protrude from the side of the first sublayer 201, and the size of the first sublayer 201 is smaller than the size of the second sublayer 202, so that the side of the second sublayer 202 facing the substrate 120 can form an inward concave structure. When the light-emitting unit 400 is prepared later, the light-emitting material can be separated by the isolation structure 200 to form independent light-emitting units 400 corresponding to the isolation opening 210.

[0058] Optional, such as Figure 4As shown, the isolation structure 200 may further include a third sublayer 203. The third sublayer 203 is located on the side of the first sublayer 201 facing the array substrate 100. The orthographic projection of the first sublayer 201 on the array substrate 100 is located within the orthographic projection of the third sublayer 203 on the array substrate 100. That is, the size of the first sublayer 201 is smaller than that of the third sublayer 203. During the preparation process of the first sublayer 201, the third sublayer 203 can provide protection for the film layer located on the side of the isolation structure 200 facing the array substrate 100.

[0059] Optionally, the light-emitting unit 400 includes a first electrode 410, a light-emitting functional layer 420, and a second electrode 430 stacked in a direction away from the array substrate 100. The first electrode 410 may be located on the array substrate 100 and within the pixel opening 320, or the pixel defining portion 310 may surround the first electrode 410 so that the first electrode 410 is exposed from the pixel opening 320. The light-emitting functional layer 420 is located within the pixel opening 320. Optionally, the material of the isolation structure 200 may include a conductive material, and the second electrode 430 and the isolation structure 200 may overlap each other, so that the second electrodes 430 can be interconnected through the isolation structure 200 to form a surface electrode.

[0060] In some optional embodiments, adjacent light-transmitting holes 220 and isolation openings 210, such as Figure 2 and Figure 7 As shown, the orthographic projection of the recessed portion 220d on the substrate 120 has a first side 230 facing the orthographic projection of the isolation opening 210 on the substrate 120, and the orthographic projection of the protruding portion 210a on the substrate 120 has a second side 240 facing the first side 230, and the distance between the first side 230 and the second side 240 is a preset distance h.

[0061] In these optional embodiments, the recessed portion 220d is recessed to form the first side 230, and the protruding portion 210a is protruding to form the second side 240. The minimum distance between the first side 230 and the second side 240 along the preset direction is greater than or equal to the preset distance h, so that the distance between the first side 230 and the second side 240 is small, and the opening size of the light-transmitting hole 220 can be increased as much as possible.

[0062] Optional, such as Figure 7 As shown, the shapes of the first side 230 and the second side 240 are adapted to each other, so as to increase the distribution area of ​​the light-transmitting holes 220 as much as possible and improve the mutual influence between the light-transmitting holes 220 and the isolation opening 210 .

[0063] Optionally, the first side 230 and the second side 240 are arranged at equal intervals. The first side 230 and the second side 240 are arranged at equal intervals within a process tolerance range. For example, the second side 240 is an arcuate edge that is convex away from the center of the isolation opening 210, and the first side 230 is an arcuate edge that is concave away from the center of the isolation opening 210 and concave toward the interior of the first light-transmitting hole 221, so that the first side 230 and the second side 240 can be arranged at equal intervals.

[0064] In these optional embodiments, the first side edges 230 and the second side edges 240 are arranged at equal intervals, which can improve the influence of the light-transmitting holes 220 on the isolation opening 210 while ensuring that the light-transmitting holes 220 have a sufficiently large distribution area.

[0065] Optionally, the first side 230 and the second side 240 are curved. Optionally, to improve diffraction between light-emitting units 400 of different colors, the orthographic projection of the isolation opening 210 on the array substrate 100 is circular, elliptical, or the like. In this embodiment of the present application, the orthographic projection of the isolation opening 210 on the array substrate 100 is elliptical, and the second side 240 is a portion of the ellipse. The first side 230 can be a portion of the ellipse, such that both the first side 230 and the second side 240 are curved, and the first side 230 and the second side 240 can be equidistant from each other.

[0066] Optionally, the first side edge 230 may be provided at the first light-transmitting hole 221 and / or the second light-transmitting hole 222 .

[0067] Optionally, the first side 230 includes a first sub-edge 231 arranged at the first light-transmitting hole 221 toward the isolation opening 210 and a second sub-edge 232 arranged at the second light-transmitting hole 222 toward the isolation opening 210, and the length of the first sub-edge 231 in the second direction Y is less than the length of the second sub-edge 232 in the second direction Y.

[0068] In these optional embodiments, a first sub-edge 231 is provided on the first light-transmitting hole 221, a second sub-edge 232 is provided on the second light-transmitting hole 222, 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.

[0069] Optionally, the second side edge 240 includes a third sub-edge 241 facing the first sub-edge 231 and a fourth sub-edge 242 facing the second sub-edge 232. The spacing between the first sub-edge 231 and the third sub-edge 241 can 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 can be smaller than the spacing between the second sub-edge 232 and the fourth sub-edge 242, so that the first light-transmitting hole 221 and the second light-transmitting hole 222 can be more compatible with the distribution pattern of the metal structure 110 in the array substrate 100.

[0070] The light-transmitting hole 220 may be in the shape of an inwardly concave polygon, one side of which is a first side 230 .

[0071] Optionally, the inner wall of the light-transmitting hole 220 has a recessed portion 220d that is recessed away from the isolation opening 210, and the first side 230 is disposed in the recessed portion 220d. In these optional embodiments, in order to adapt to the circular or elliptical isolation opening 210, the recessed portion 220d can be provided on the light-transmitting hole 220, and the first side 230 can be disposed in the recessed portion 220d, so as to ensure that the first side 230 and the second side 240 are equally spaced.

[0072] In some embodiments, the light-transmitting hole 220 is located on one side of the isolation opening 210 in the first direction X. The light-transmitting hole 220 has a first straight side 220a disposed opposite the first side 230 along the first direction X. The first straight side 220a extends linearly along the second direction Y. By providing the light-transmitting hole 220 with a straight side and a side, the shape of the light-transmitting hole 220 is adapted to the shape of the isolation opening 210 while also maximizing the size of the light-transmitting hole 220 to increase light transmittance.

[0073] Optionally, the first straight edge 220a is connected to a second straight edge 220b at both ends in the second direction Y.

When the first side edge 230 is provided at the second light-transmitting hole 222 and the second light-transmitting hole 222 includes a second sub-edge 232, the second sub-edge 232 and the first straight edge 220a are disposed opposite to each other along the first direction X.

[0075] Optionally, the first straight edge 220a is connected to a second straight edge 220b at both ends in the second direction Y.

When the first side 230 includes a first sub-edge 231, the first sub-edge 231 can be connected to the second straight edge 220b via the third straight edge 220c. When the first side 230 includes a second sub-edge 232, the second sub-edge 232 can be connected to the second straight edge 220b via the third straight edge 220c. This further expands the distribution area of ​​the light-transmitting hole 220 and simplifies the shape of the light-transmitting hole 220.

[0077] Optionally, the same light-transmitting hole 220 may include two third straight edges 220c, i.e., a third straight edge 220c is provided on both sides of the first side edge 230 in the second direction Y, and the two ends of the first side edge 230 are connected to the second straight edge 220b via the third straight edges 220c, thereby further expanding the distribution area of ​​the light-transmitting hole 220. Optionally, the two ends of the first sub-edge 231 may be connected to the second straight edge 220b via the third straight edges 220c. Optionally, the two ends of the second sub-edge 232 may be connected to the second straight edge 220b via the third straight edges 220c.

[0079] Optionally, when the light-transmitting hole 220 includes a first side edge 230, the first side edge 230 is located on the side of the light-transmitting hole 220 facing the first isolation opening 211. The first isolation opening 211 generally has a larger distribution area, and the first side edge 230 being located on the side of the light-transmitting hole 220 facing the first isolation opening 211 can reduce the mutual interference between the positions of the light-transmitting hole 220 and the first isolation opening 211.

[0080] Optional, such as Figure 8As shown, at least one light-transmitting hole 220 has at least two recessed portions 220d facing at least two isolation openings 210 located on its peripheral side, and each recessed portion 220d includes a first side 230; a plurality of isolation openings 210 are arranged around the peripheral side of the at least one light-transmitting hole 220, and at least two isolation openings 210 among the plurality of isolation openings 210 have a protruding portion 210a facing the same light-transmitting hole 220, and each protruding portion 210a includes a second side 240; the shapes of the first side 230 and the corresponding second side 240 are adapted to each other.

[0081] At least one light-transmitting hole 220 has at least two recessed portions 220d facing at least two isolation openings 210 located on its peripheral side, which means that at least one light-transmitting hole 220 has at least two recessed portions 220d, and at least two isolation openings 210 are arranged on the peripheral side of the light-transmitting hole 220, and the recessed portions 220d and the isolation openings 210 are arranged correspondingly.

[0082] In these optional embodiments, multiple isolation openings 210 may be provided on the surrounding side of the same light-transmitting hole 220. By providing multiple recessed portions 220d on the same light-transmitting hole 220 to match the protruding portions 210a on at least two of the multiple isolation openings 210 on the surrounding side of the same light-transmitting hole 220, the shape of the light-transmitting hole 220 can be more adapted to the shapes of the multiple isolation openings 210 on the surrounding side, and the distribution area of ​​the light-transmitting hole 220 can be further increased, thereby improving the transmittance.

[0083] Optional, such as Figure 8 As shown, the light-transmitting hole 220 has two first side edges 230, and two isolation openings 210 are arranged around the same light-transmitting hole 220 and each has a second side edge 240.

Both isolation openings 210 are provided with a protruding portion 210a and a second side edge 240, which can further increase the distribution area of ​​the light-transmitting holes 220 and improve light transmittance.

The four isolation openings 210 are each provided with a protruding portion 210a and a second side 240, which can further increase the distribution area of ​​the light-transmitting holes 220 and improve light transmittance.

[0085] Optionally, the first side 230 includes at least one of a straight line segment and a curved line segment, so that the shape of the light-transmitting hole 220 can be more compatible with the shapes of the plurality of isolation openings 210 located around it, thereby further increasing the distribution area of ​​the light-transmitting hole 220 and improving the light transmittance.

[0086] In some optional embodiments, such as Figure 2 and Figure 5 As shown, the isolation opening 210 includes a first isolation opening 211 and a second isolation opening 212, and the first isolation opening 211 and the second isolation opening 212 are alternately arranged along the first direction X to form a first opening group H1; the first light-transmitting holes 221 and the second light-transmitting holes 222 are alternately arranged along the first direction X, so that a first light-transmitting hole 221 or a second light-transmitting hole 222 is provided between each adjacent first isolation opening 211 and the second isolation opening 212, and the recessed portion 220d is provided in at least one of the first light-transmitting hole 220 and the second light-transmitting hole 220.

[0088] There are various ways to arrange the light-emitting unit 400. Optionally, the light-emitting unit 400 may include a first light-emitting unit 401, a second light-emitting unit 402, and a third light-emitting unit 403 of different colors. The first light-emitting unit 400 may be arranged corresponding to the first isolation opening 211, and the second light-emitting unit 400 may be arranged corresponding to the second isolation opening 212. The isolation opening 210 may further include a third isolation opening 213, and the third light-emitting unit 403 may be arranged corresponding to the third isolation opening 213.

[0089] In some optional embodiments, such as Figure 2 As shown, the orthographic projection of the metal structure 110 on the substrate 120 is located outside the orthographic projections of the first light-transmitting hole 221 and the second light-transmitting hole 222 on the substrate 120 .

[0090] In these optional embodiments, the setting position of the metal structure 110 and the first light-transmitting hole 221 and the second light-transmitting hole 222 are completely misaligned, which can ensure the transmittance of the area where the first light-transmitting hole 221 and the second light-transmitting hole 222 are located, thereby improving the transmittance of the display panel.

[0091] The metal structure 110 may include a conductive structure in the array substrate 100. For example, the metal structure 110 includes at least one of a gate G, a signal line, and a capacitor plate C. The placement of at least one of the gate G, the signal line, and the capacitor plate C is completely offset from the first light-transmitting hole 221 and the second light-transmitting hole 222, thereby ensuring light transmittance in the region where the first light-transmitting hole 221 and the second light-transmitting hole 222 are located, thereby improving the light transmittance of the display panel. The signal line may be at least one of a scan signal line and a power signal line.

[0092] Optionally, as described above, the display panel also includes a driving circuit T, the driving circuit T includes a metal oxide transistor and a low-temperature polysilicon transistor, the gate G includes a first gate arranged in the metal oxide transistor and a second gate arranged in the low-temperature polysilicon transistor, and the metal structure 110 includes at least one of the first gate and the second gate.

[0093] In these optional embodiments, the driving circuit T includes metal oxide transistors and low-temperature polysilicon transistors of different types, the gate G includes a first gate and a second gate located in different types of transistors, and the metal structure 110 includes at least one of the first gate and the second gate, so that the setting position of at least one of the first gate and the second gate is completely misaligned with the first light-transmitting hole 221 and the second light-transmitting hole 222, which can ensure the transmittance of the area where the first light-transmitting hole 221 and the second light-transmitting hole 222 are located, thereby improving the transmittance of the display panel.

[0094] The metal oxide transistor may be an indium gallium zinc oxide transistor. Optionally, the driving circuit T may include a driving transistor and a switching transistor, with one of the metal oxide transistor and the low-temperature polysilicon transistor being the driving transistor and the other being the switching transistor, such that the gates of the driving transistor and / or the switching transistor are completely misaligned with the first light-transmitting hole 221 and the second light-transmitting hole 222. Optionally, the driving circuit may further include a threshold compensation transistor, a reset transistor, a light-emitting control transistor, etc., and the orthographic projections of the gates of these different types of transistors on the substrate 120 may all be completely outside the orthographic projections of the first light-transmitting hole 221 and the second light-transmitting hole 222 on the substrate 120, thereby further improving the transmittance of the display panel.

[0095] Please refer to the above description, the isolation opening 210 may further include a third isolation opening 213, and a plurality of third isolation openings 213 are arranged at intervals along the first direction X to form a second opening group H2. Figure 6 As shown, the light-transmitting holes 220 further include third light-transmitting holes 223, which are located between at least two adjacent third isolation openings 213. By adding third light-transmitting holes 223 located between two adjacent third isolation openings 213 in the second opening group H2, the total distribution area of ​​the light-transmitting holes 220 can be further increased, thereby improving the light transmittance of the display panel.

[0096] Optionally, the orthographic projection area of ​​the first isolation opening 211 on the array substrate 100 is larger than the orthographic projection area of ​​the second isolation opening 212 on the array substrate 100, and the orthographic projection area of ​​the second isolation opening 212 on the array substrate 100 is larger than the orthographic projection area of ​​the third isolation opening 213 on the array substrate 100. That is, the distribution area of ​​the third isolation opening 213 for accommodating the blue light-emitting unit 400 is the largest, which can increase the distribution area of ​​the blue light-emitting unit 400 and improve the service life of the blue light-emitting unit 400.

[0097] Optionally, two second isolation openings 212 and two first isolation openings 211 are provided on the peripheral side of the third isolation opening 213, and the two first isolation openings 211 and the two second isolation openings 212 are alternately arranged on the peripheral side of the third isolation opening 213, so that two second light-emitting units 400 and two first light-emitting units 400 are provided on the peripheral side 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 on the peripheral side of the third light-emitting unit 400, which can reduce the distance between the third light-emitting unit 400 and the first light-emitting unit 400 and the second light-emitting unit 400, thereby improving the display effect of the display panel.

[0098] Optionally, the orthographic projection area of ​​the third light transmission hole 223 on the array substrate 100 is smaller than the orthographic projection area of ​​the first light transmission hole 221 or the second light transmission hole 222 on the array substrate 100 , so that the shape and size of the third light transmission hole 223 are more compatible with the third isolation opening 213 .

[0099] In some optional embodiments, the first opening group H1 and the second opening group H2 are alternately arranged along the second direction Y, and the first opening group H1 and the second opening group H2 are staggered so that the first isolation opening 211 is correspondingly located 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 first isolation opening 211 or the second isolation opening 212 in the second direction Y.

[0100] In these optional embodiments, the first opening group H1 and the second opening group H2 are alternately arranged along the second direction Y, so that the first isolation opening 211 can be correspondingly located between two adjacent third isolation openings 213, and the third light-transmitting hole 223 located between two adjacent third isolation openings 213 can be located on one side of the first isolation opening 211 or the second isolation opening 212 in the second direction Y, so that the distribution of the isolation openings 210 and the light-transmitting holes 220 is more scientific and reasonable, and the distribution of multiple light-transmitting holes 220 is more uniform.

[0101] Optionally, at least one second isolation opening 212 is located 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.

[0102] In these optional 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.

[0103] Optionally, each third isolation opening 213 is provided with a third light-transmitting hole 223 on one side in the second direction Y, which can further increase the distribution area of ​​the light-transmitting holes 220. For example, one of the third isolation openings 213 is provided with a third light-transmitting hole 223 on one side in the second direction Y, while no third light-transmitting hole 223 is provided on the other side in the third direction. Thus, among two adjacent groups of third isolation openings 213, one group of adjacent third isolation openings 213 has a third light-transmitting hole 223 provided between them, while the other group of adjacent third isolation openings 213 has no third light-transmitting hole 223 provided between them.

[0104] Optionally, in two adjacent first isolation openings 211 and second isolation openings 212, the first isolation opening 211 is provided with a third light-transmitting hole 223 on one side of the second direction Y, and the second isolation opening 212 is provided with a third light-transmitting hole 223 on the other side of the second direction Y, so that the distribution of the third light-transmitting holes 223 is more uniform.

[0105] In some optional embodiments, the second opening group H2 further includes a first gap Q1 and a second gap Q2 located between two adjacent third isolation openings 213 . The first gap Q1 and the second gap Q2 are alternately arranged along the first direction X, and the third light-transmitting hole 223 is located in the first gap Q1 .

[0106] In these optional embodiments, a third light-transmitting hole 223 is provided in the first gap Q1 , but not in the second gap Q2 , so as to make room for the metal structure 110 and reduce the impact of ambient light on the metal structure 110 located in the second gap Q2 .

[0107] Optionally, conductive traces are further provided on the substrate 120. The wiring density of the conductive traces at the location of the first gap Q1 is less than the wiring density of the conductive traces at the location of the second gap Q2. By providing the third light-transmitting hole 223 in the first gap Q1, where the wiring density is less, the influence of ambient light on the conductive traces can be reduced while improving the transmittance.

[0108] Optional, such as Figure 6As shown, the orthographic projection of at least one conductive trace on the substrate 120 and the orthographic projection of the third light-transmitting hole 223 on the substrate 120 at least partially overlap. That is, the third light-transmitting hole 223 can be provided with a corresponding conductive trace, for example, the conductive trace passes through the middle of the third light-transmitting hole 223, which can improve the transmittance while simplifying the arrangement of the third light-transmitting hole 223.

[0109] Optionally, the conductive trace includes a power signal line, and the orthographic projection of the power signal line on the substrate 120 at least partially overlaps the orthographic projection of the third light-transmitting hole 223 on the substrate 120. Optionally, the power signal line includes at least one of a driving power voltage signal line VDD and a voltage reference signal line.

[0110] There are many ways to set the orthographic projection shape of the third light transmission hole 223 on the array substrate 100. For example, the orthographic projection of the third light transmission hole 223 on the array substrate 100 is polygonal, circular, elliptical, etc.

[0111] Alternatively, as Figures 6 to 8 As shown, the shape of the third light-transmitting hole 223 matches the shape of the third isolation openings 213 located on both sides thereof. For example, in some optional embodiments, the third light-transmitting hole 223 includes a third side 250 facing the third isolation opening 213, and the third isolation opening 213 has a fourth side 260 facing the third side 250, and the third side 250 and the fourth side 260 are arranged at equal distances.

[0112] The equal distance between the third side 250 and the fourth side 260 does not mean that they are strictly equal in a mathematical and geometric sense, but refers to that the equal distance between the third side 250 and the fourth side 260 is within a process manufacturing error range.

[0113] In these optional embodiments, the third side 250 and the fourth side 260 are equally spaced, allowing the shape of the third light-transmitting holes 223 to better match the shape of the third isolation opening 213, thereby maximizing the distribution area of ​​the third light-transmitting holes 223 and improving the light transmittance of the display panel. Furthermore, the equal spacing between the third side 250 and the fourth side 260 ensures that the third light-transmitting holes 223 have a sufficiently large distribution area, thereby reducing the mutual interference and influence between the third light-transmitting holes 223 and the third isolation opening 213.

[0114] Optionally, the third side 250 and the fourth side 260 may be arc-shaped.

[0115] Optionally, the third side 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 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 on two adjacent third isolation openings 213, the fifth sub-edge 251 and the seventh sub-edge 261 being equidistant, and the sixth sub-edge 252 and the eighth sub-edge 262 being equidistant.

[0116] Optionally, the third light-transmitting hole 223 has a second center line P2 extending along the second direction Y, and the fifth sub-edge 251 and the sixth sub-edge 252 are symmetrically arranged about the second center line P2.

[0117] In these optional embodiments, the distances from the edges of the third light-transmitting hole 223 to the edges of the third isolation openings 213 on both sides thereof are equal, so that the shapes of the third light-transmitting hole 223 and the third isolation openings 213 on both sides thereof are more adapted.

[0118] Optionally, the third light-transmitting hole 223 has a second midline P2 extending along the second direction Y, and the fifth sub-edge 251 and the sixth sub-edge 252 are symmetrically arranged about the second midline P2. Optionally, the second midline P2 passes through the center of the third light-transmitting hole 223 in the first direction X, and the second midline P2 extends along the second direction Y. The symmetry of the fifth sub-edge 251 and the sixth sub-edge 252 about the second midline P2 can simplify the shape of the third light-transmitting hole 223 and facilitate its preparation and molding.

[0119] In some optional embodiments, the third light-transmitting hole 223 includes a first segment 223a and a second segment 223b distributed in sequence along the second direction Y, the third side 250 is set on the second segment 223b, 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.

[0120] In these optional embodiments, the third light-transmitting hole 223 is set to a first segment 223a and a second segment 223b with different widths, so that the shape of the third light-transmitting hole 223 is more adapted to the shape of the gap between two adjacent third isolation openings 213, and the distribution area of ​​the third light-transmitting hole 223 can be appropriately expanded.

[0121] For example, the two third isolation openings 213 located on either side of the third light-transmitting hole 223 in the first direction X are elliptical in shape, and in the direction from the first segment 223a to the second segment 223b, the two third isolation openings 213 are arranged in an inclined direction approaching each other. This results in the gap width at the location of the first segment 223a being larger than the gap width at the location of the second segment 223b. Therefore, setting the width of the first segment 223a larger can appropriately increase the distribution area of ​​the third light-transmitting hole 223 and reduce the possibility of mutual interference between the third light-transmitting hole 223 and the third isolation openings 213. For example, if the third isolation opening 213 is elliptical in shape and the two third isolation openings 213 are arranged in an inclined direction approaching each other, it can be understood that the lines along which the major axes of the two third isolation openings 213 intersect.

[0122] Optionally, the first segment 223a is rectangular and has the same width in the second direction Y, which can simplify the shape of the first segment 223a and the shape of the third light transmission hole 223 and facilitate the preparation and molding of the third light transmission hole 223.

[0123] Preferably, the width of the second segment 223b in the first direction X gradually decreases in a direction away from the first segment 223a, so that the shape of the second segment 223b is more adapted to the shape of the gap at its location.

[0124] Optionally, the second segment 223b has a fourth straight edge 223b1, the fourth straight edge 223b1 is connected between the fifth sub-edge 251 and the sixth sub-edge 252, the second median line P2 passes through the midpoint of the fourth straight edge 223b1 in the first direction X, and the fourth straight edge 223b1 extends in a straight line along the first direction X to simplify the shape of the second segment 223b, simplify the shape of the third light-transmitting hole 223, and facilitate the preparation and molding of the third light-transmitting hole 223.

[0125] In some optional embodiments, in the first light-transmitting hole 221 and the first isolation openings 211 and second isolation openings 212 located on either side thereof, the distance from the first isolation opening 211 to the first light-transmitting hole 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 openings 211 and the second isolation openings 212 are not symmetrically arranged about the first light-transmitting hole 221, so that the first light-transmitting hole 221 can be arranged in an area with a lower density of the metal structure 110 to ensure light transmittance.

[0126] In some optional embodiments, the distance between the second light-transmitting hole 222 and the first isolation opening 211 and the second isolation opening 212 located on either side thereof is not equal to the distance between the first isolation opening 211 and the second light-transmitting hole 222. That is, the first isolation opening 211 and the second isolation opening 212 are not symmetrically arranged about the second light-transmitting hole 222, so that the second light-transmitting hole 222 can be arranged in an area with a lower density of the metal structure 110 to ensure light transmittance.

[0127] In some optional embodiments, in the first isolation opening 211 and the first light-transmitting holes 221 and the second light-transmitting holes 222 located on both sides thereof, the distance from the first light-transmitting hole 221 to the first isolation opening 211 is not equal to the distance from the second light-transmitting hole 222 to the first isolation opening 211. That is, the first light-transmitting holes 221 and the second light-transmitting holes 222 are not symmetrically arranged about the first isolation opening 211, so that the first light-transmitting holes 221 and the second light-transmitting holes 222 can be arranged in an area with a lower density of the metal structure 110 to ensure light transmittance.

[0128] In some optional embodiments, in the second isolation opening 212 and the first light-transmitting holes 221 and the second light-transmitting holes 222 located on both sides thereof, the distance from the first light-transmitting hole 221 to the second isolation opening 212 is not equal to the distance from the second light-transmitting hole 222 to the second isolation opening 212. That is, the first light-transmitting holes 221 and the second light-transmitting holes 222 are not symmetrically arranged about the second isolation opening 212, so that the first light-transmitting holes 221 and the second light-transmitting holes 222 can be arranged in an area with a lower density of the metal structure 110 to ensure light transmittance.

[0129] In some optional embodiments, the orthographic projection area of ​​the first light-transmitting hole 220 on the substrate 120 is larger than the orthographic projection area of ​​the second light-transmitting hole 220 on the substrate 120. By providing the first light-transmitting holes 221 and the second light-transmitting holes 222 of different areas, each light-transmitting hole 220 can be better adapted to gaps of different sizes, thereby further increasing the overall distribution area of ​​the light-transmitting holes 220.

[0130] In other optional 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 hole 220.

[0131] Optional, please also see Figure 2 and Figure 7The first light-transmitting hole 221 and the second light-transmitting hole 222 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 the preparation 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, and b1 and b2 are equal.

[0132] Optionally, the width of at least some of the first light-transmitting holes 221 in the first direction X is greater than the width of the second light-transmitting holes 222 in the first direction X. This allows the first light-transmitting holes 221 and the second light-transmitting holes 222 to have different distribution areas, and facilitates the shapes of the first light-transmitting holes 221 and the second light-transmitting holes 222 to adapt to the distribution pattern of the metal structure 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 greater than W2.

[0133] There are many ways to set the shapes of the first light transmission hole 221 and the second light transmission hole 222. For example, the shapes of the first light transmission hole 221 and the second light transmission hole 222 can be polygonal, circular, elliptical, etc. The first light transmission hole 221 and the second light transmission hole 222 can also be irregularly shaped.

[0134] As above, Figure 3 As shown, the display panel further includes a first encapsulation layer 500, which includes encapsulation portions 510 spaced apart from each other to encapsulate each isolation opening 210, and a clearance gap is formed between adjacent encapsulation portions 510, wherein the clearance gap at the orthographic projection on the substrate 120 at least partially overlaps with the orthographic projection of the light-transmitting hole 220 at the substrate 120.

[0135] The encapsulation portion 510 is used to encapsulate the isolation opening 210, that is, the encapsulation portion 510 is used to encapsulate the light-emitting unit 400 at least partially located in the isolation opening 210. The encapsulation portion 510 may extend from the isolation opening 210 to a side of the isolation structure 200 facing away from the substrate.

[0136] In these optional embodiments, the orthographic projection of the clearance on the substrate 120 at least partially overlaps with the orthographic projection of the light-transmitting hole 220 on the substrate 120, that is, the light-transmitting hole 220 and the packaging portion 510 are at least partially misaligned, which can improve the transmittance of the area where the light-transmitting hole 220 is located.

[0137] The orthographic projection of the light-transmitting hole 220 on the substrate 120 is located within the clearance gap, that is, the light-transmitting hole 220 and the packaging portion 510 are completely misaligned, so as to further improve the light transmittance of the area where the light-transmitting hole 220 is located.

[0138] Optionally, the material of the first encapsulation layer 500 can protect the inorganic material, so that the first encapsulation layer 500 has good compactness.

[0139] Optional, such as Figure 4 As shown, the encapsulation layer further includes a second encapsulation layer 600 located on a side of the first encapsulation layer 500 away from the array substrate 100 . The material of the second encapsulation layer 600 may include an organic material.

[0140] Optionally, the encapsulation layer further includes a third encapsulation layer 700 located on the side of the second encapsulation layer 600 away from the array substrate 100 . The material of the third encapsulation layer 700 may be the same as that of the first encapsulation layer 500 , for example, the material of the third encapsulation layer 700 is an inorganic material.

[0141] Optionally, when the pixel definition layer 300 includes a pixel defining portion 310 and a pixel opening 320, and the pixel opening 320 is connected to the isolation opening 210, the orthographic projection of the light-transmitting hole 220 on the substrate 120 is located within the orthographic projection of the pixel defining portion 310 on the substrate 120. In other words, no through hole is provided on the pixel defining portion 310 corresponding to the light-transmitting hole 220, which can simplify the arrangement of the pixel defining portion 310.

[0142] Optionally, the pixel defining portion 310 and the second encapsulation layer 600 are in contact with each other in the light-transmitting hole 220, thereby improving the problem of easy peeling of the encapsulation layer.

[0143] Optionally, the display panel further includes a planarization layer and a buffer layer sequentially disposed on the side of the definition layer facing the substrate 120, and the orthographic projection of the light-transmitting hole 220 on the substrate 120 is located within the orthographic projection of at least one of the buffer layer and the planarization layer on the substrate 120. The buffer layer and the planarization layer are not perforated in the region where the light-transmitting hole 220 is located, so that the buffer layer and the planarization layer can provide better support for film layers such as the isolation structure 200.

[0144] There are various arrangements of the light-emitting units 400. For example, multiple light-emitting units 400 may be arranged in an array within the display area of ​​the display panel along the first direction X and the second direction Y. Multiple isolation openings 210 may be 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 hole 221 may be located on one side of the isolation structure 200 in the first direction X, and the second light-transmitting hole 222 may be located on one side of the isolation opening 210 in the second direction Y.

[0145] In some optional embodiments, the minimum spacing between the light-transmitting hole 220 and the isolation opening 210 is 3 μm to 4 μm. That is, the minimum spacing between the orthographic projection edge of the light-transmitting hole 220 on the array substrate 100 and the orthographic projection edge of the isolation opening 210 on the array substrate 100 is 3 μm to 4 μm. This can improve the problem of excessive spacing between the light-transmitting hole 220 and the isolation opening 210, which affects the distribution area of ​​the light-transmitting hole 220 and the transmittance of the display panel; it can also improve the problem of excessive spacing between the light-transmitting hole 220 and the isolation opening 210, which increases the process difficulty and causes the light-transmitting hole 220 and the isolation opening 210 to affect each other.

[0146] Optionally, the minimum spacing between the first light-transmitting hole 221 and any one of the first isolation opening 211, the second isolation opening 212, and the third isolation opening 213 is 3 μm to 4 μm. The minimum spacing between the second light-transmitting hole 222 and any one of the first isolation opening 211, the second isolation opening 212, and the third isolation opening 213 is 3 μm to 4 μm. The minimum spacing between the third light-transmitting hole 223 and any one of the first isolation opening 211, the second isolation opening 212, and the third isolation opening 213 is 3 μm to 4 μm.

[0147] In any of the above embodiments, the display panel includes a display area, the display area includes a main display area AA2 and a translucent display area AA1, and the light-transmitting hole 220 is located in the translucent display area AA1 to improve the transmittance of the translucent display area AA1 and facilitate the integration of the photosensitive module under the screen of the translucent display area AA1.

[0148] like Figures 1 to 9 As shown, the first aspect of the present application also provides a display panel, which includes: an array substrate 11, the array substrate 11 includes a substrate 120 and a metal structure 110 arranged on the substrate 120; an isolation structure 200, which is arranged on one side of the array substrate 11, and the isolation structure 200 encloses an isolation opening 210 and a light-transmitting hole 220, and the orthographic projection of the light-transmitting hole 220 on the substrate 120 and the orthographic projection of the metal structure 110 on the substrate 120 are at least partially staggered, and the isolation opening 210 is used to accommodate at least part of the light-emitting unit 400; wherein, the light-transmitting hole 220 includes 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 peripheral side of the same isolation opening 210, and the orthographic projection shape of the first light-transmitting hole 221 on the substrate 120 is different from the orthographic projection shape of the second light-transmitting hole 222 on the substrate 120.

[0149] In the embodiment of the present application, by providing first light-transmitting holes 221 and second light-transmitting holes 222 of different shapes, different light-transmitting holes 220 can be adapted to the areas in which they are located, and the overall distribution area of ​​the light-transmitting holes 220 can be expanded as much as possible, thereby improving the transmittance.

[0150] The display panel of the present embodiment and the display panel of any of the above embodiments may be cross-referenced with each other, and the same structures in the display panel of the present embodiment and the display panel of any of the above embodiments are not repeated here. For example, the display panel of the present embodiment may include the above-mentioned recessed portion 220d, protruding portion 210a, and other structures.

[0151] like Figures 1 to 9 As shown, the first aspect of the present application further provides a display panel, comprising: an array substrate 11, the array substrate 11 comprising a substrate 120 and a first active layer 130 disposed on the substrate 120; an isolation structure 200 disposed on one side of the array substrate 11, the isolation structure 200 enclosing a plurality of isolation openings 210 and a plurality of light-transmitting holes 220, wherein the orthographic projection of the light-transmitting holes 220 on the substrate 120 and the orthographic projection of the first active layer 130 on the substrate 120 are at least partially staggered; and a light-emitting unit 400 disposed corresponding to the isolation opening 210. The above-mentioned display panel 1 provided in the present application comprises an array substrate 11, a light-emitting unit 400, and an 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 encloses the isolation opening 210 and the light-transmitting hole 220. The isolation opening 210 is used to expose the light-emitting unit 400 to realize light emission. The light-transmitting holes 220 are used to transmit light through the display panel 1, thereby improving the light transmittance of the display panel 1. The orthographic projection of the light-transmitting hole 220 on the substrate 120 and the orthographic projection of the first active layer 130 on the substrate 120 are at least partially staggered. This can reduce the impact of natural light within the light-transmitting hole 220 on the first active layer 130, improve the performance of the first active layer 130, and thus improve the performance of the display panel.

[0152] Optional, such as Figure 3 and Figure 8 As shown, the first active layer 130 includes a first channel region 131, and the orthographic projection of the light-transmitting hole 220 on the substrate 120 and the orthographic projection of the first channel region 131 on the substrate 120 are staggered. That is, the staggered arrangement of the first channel region 131 and the light-transmitting hole 220 can reduce or even eliminate the amount of light incident on the first channel region 131 through the light-transmitting hole 220, thereby reducing the impact of photogenerated carriers on the first channel region 131, improving the performance of the first channel region 131, and thereby enhancing the performance of the display panel.

[0153] The material of the first active layer 130 can be configured in various ways. Optionally, the material of the first active layer 130 includes a metal oxide semiconductor material, such as an indium gallium zinc oxide semiconductor material. Alternatively, as mentioned above, when the driving circuit T includes a metal oxide transistor and a low-temperature polysilicon transistor, at least a portion of the first active layer 130 can serve as the semiconductor portion of the metal oxide transistor.

[0154] In some optional embodiments, such as Figure 3 and Figure 8 As shown, the display panel further includes a second active layer 140. The orthographic projection of the second active layer 140 on the substrate 120 and the orthographic projection of the light-transmitting hole 220 on the substrate 120 are at least partially staggered. This can reduce the impact of natural light within the light-transmitting hole 220 on the second active layer 140, improve the performance of the second active layer 140, and thus enhance the performance of the display panel.

[0155] Optional, such as Figure 3 As shown, the second active layer 140 includes a second channel region 141. The orthographic projection of the second channel region 141 on the substrate 120 and the orthographic projection of the light-transmitting hole 220 on the substrate 120 are at least partially staggered. That is, the staggered arrangement of the second channel region 141 and the light-transmitting hole 220 can reduce or even eliminate the amount of light incident on the second channel region 141 through the light-transmitting hole 220, reduce the impact of photogenerated carriers on the second channel region 141, improve the performance of the second channel region 141, and thus enhance the performance of the display panel.

[0156] Or, as Figure 8 As shown, a light shielding layer 150 is disposed between the second channel region 141 and the isolation structure 200. The orthographic projection of the second channel region 141 on the substrate is located within the orthographic projection of the light shielding layer 150 on the substrate. The presence of the light shielding layer 150 can reduce or even eliminate the amount of light incident on the second channel region 141 through the light-transmitting hole 220, thereby reducing the impact of photogenerated carriers on the second channel region 141, improving the performance of the second channel region 141, and thereby enhancing the performance of the display panel.

[0157] The light shielding layer 150 can be disposed in various locations. The light shielding layer 150 can be disposed on the same layer as the capacitor plate, gate, signal line, etc. Optionally, the light shielding layer 150 can be made of a metal light shielding material, so that the light shielding layer 150 has good light shielding performance.

[0158] Optionally, the second active layer 140 is made of 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 portion of the second active layer 140 may serve as a semiconductor portion of the low-temperature polysilicon transistor.

[0159] Optionally, the first active layer 130 and the second active layer 140 are provided in different layers, and the first active layer 130 and the second active layer 140 may be made of different materials.

[0160] Optionally, the first active layer 130 is located on the side of the second active layer 140 facing away from the substrate 120. This facilitates the preparation of the second active layer 140 before the first active layer 130, and can reduce the impact of the preparation of the second active layer 140 on the first active layer 130.

[0161] Optionally, the display panel of the embodiment of the present application and the display panel of any of the above embodiments may be cross-referenced to each other, and the same structural features in the embodiment of the present application and the display panel of any of the above embodiments will not be repeated here.

[0162] like Figures 10 to 16 As shown, the first aspect of the present application further provides a display panel, comprising: 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 includes a plurality of light-emitting units 400. At least a portion of the isolation structure 200 encloses an isolation opening 210 and a light-transmitting hole 220. The isolation opening 210 is used to expose the light-emitting unit 400, and the light-transmitting hole 220 is formed between at least a portion of adjacent isolation openings 210. The isolation structure 200 includes a first equal-width segment 153 enclosing the light-transmitting hole 220. At least the orthographic projection of the first equal-width segment 153 on the array substrate 11 is located between the orthographic projection of the light-transmitting hole 220 on the array substrate 11 and the orthographic projection of the isolation opening 210 on the array substrate 11. The first equal-width segment 153 is arranged to have a uniform width, and the width direction of the first equal-width segment 153 is the direction in which the orthographic projection of the light-transmitting hole 220 on the array substrate 11 and the orthographic projection of the isolation opening 210 on the array substrate 11 point to the other.

[0163] Optionally, the array substrate 11 and the substrate in the priority case with application number 202410382548.0 may have the same structure as the display panel. The isolation opening 210 and the opening portion in the priority case with application number 202410382548.0 may have the same structure.

[0164] The above-mentioned display panel 1 provided in 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, and the light-emitting units 400 are used to emit light to realize the display function of the display panel 1. The isolation structure 200 encloses an isolation opening 210 and a light-transmitting hole 220. The isolation opening 210 is used to expose the light-emitting unit 400 to realize light emission. The light-transmitting hole 220 is located between at least part of the adjacent isolation openings 210, that is, the orthographic projection of the light-transmitting hole 220 on the array substrate 11 is located between the orthographic projections of at least part of the light-emitting units 400 on the array substrate 11, thereby realizing light transmission in the area between adjacent light-emitting units 400, so as to improve the light transmittance of the display panel 1. The isolation structure 200 includes a first equal-width segment 153 enclosing the light-transmitting hole 220. The first equal-width segment 153 is located between the light-transmitting hole 220 and the isolation opening 210. The first equal-width segment 153 is set to have equal width, that is, the portion of the isolation structure 200 between the light-transmitting hole 220 and the isolation opening 210 is set to have equal width. On the premise of ensuring that the area of ​​the isolation opening 210 is constant and the manufacturing yield is guaranteed, the area of ​​the light-transmitting hole 220 is maximized, thereby increasing the distribution area of ​​the light-transmitting hole 220 and improving the transmittance of the display panel 1.

[0165] Optionally, the opening shape of the light-transmitting hole 220 can be reasonably set, for example, the shape of the light-transmitting hole 220 can be adapted to the shape of the isolation opening 210, so that the light-transmitting hole 220 is irregularly shaped, so that the first equal-width segments 153 can be set to equal width, thereby maximizing the area of ​​the light-transmitting hole 220.

[0166] Furthermore, by configuring the first equal-width segments 153 to have equal widths, the amount of light reflected by different positions of the first equal-width segments 153 tends to be consistent, thereby improving the display quality of the display panel 1. The width direction of the first equal-width segments 153 is the direction in which the orthographic projections of the light-transmitting holes 220 and the orthographic projections of the isolation openings 210 on the array substrate 11 on either side of the first equal-width segment 153 point toward the other. For example, the width direction of the first equal-width segments 153 can be the direction in which the orthographic projections of the light-transmitting holes 220 and the orthographic projections of the isolation openings 210 on the array substrate 11 on either side of the first equal-width segment 153 point toward the geometric center of the orthographic projections of the light-transmitting holes 220 and the orthographic projections of the isolation openings 210 on the array substrate 11 on either side of the first equal-width segment 153 point toward the geometric center of the orthographic projections of the light-transmitting holes 220 and the orthographic projections of the isolation openings 210 on the array substrate 11 on either side of the first equal-width segment 153.

[0167] In the above embodiment, if Figure 10As shown, the display panel 1 can be a transparent display panel, or the display panel 1 includes a first display area AA1 and a second display area AA2. The first display area AA1 is provided with the aforementioned light-transmitting holes 220, so that the transmittance of the first display area AA1 is greater than the transmittance of the second display area AA2. Optionally, the first display area AA1 is provided with the aforementioned first equal-width segments 153 to increase the distribution area of ​​the light-transmitting holes 220. A photosensitive module, such as a camera module or a fingerprint recognition module, can be provided below the first display area AA1. The higher transmittance of the first display area AA1 can improve the performance of the photosensitive module, thereby improving the performance of the display panel 1.

[0168] In some optional embodiments, such as Figures 10 to 14 As shown, the isolation structure 200 includes a first sublayer 201 and a second sublayer 202. The first sublayer 201 is located on the side of the second sublayer 202 facing the array substrate 11, and the orthographic projection of the first sublayer 201 on the array substrate 11 is located within the orthographic projection of the second sublayer 202 on the array substrate 11.

[0169] In these optional embodiments, the isolation structure 200 includes a first sublayer 201 and a second sublayer 202. The second sublayer 202 is located on the side of the first sublayer 201 facing away from the array substrate 11, and the orthographic projection of the first sublayer 201 on the array substrate 11 is located within the orthographic projection of the second sublayer 202 on the array substrate 11. That is, the orthographic projection area of ​​the first sublayer 201 is smaller than the orthographic projection area of ​​the second sublayer 202, and a concave portion can be formed under the second sublayer 202. When subsequently preparing the light-emitting units 400, the light-emitting material can be disconnected at the edge of the second sublayer 202 to form independent light-emitting units 400. This can omit the preparation process of a precision mask and simplify the preparation process of the display panel 1.

[0170] When the isolation structure 200 includes a first sublayer 201 and a second sublayer 202, the first equal-width segment 153 can be disposed in the first sublayer 201 or the second sublayer 202. Alternatively, the first equal-width segment 153 can be disposed in the second sublayer 202, for example, the first equal-width segment 153 includes a second subsegment 202a disposed in the second sublayer 202.

[0171] In these optional embodiments, since the size of the second sub-layer 202 is larger, the shape and size of the second sub-layer 202 determine the shape and size of the light-transmitting hole 220. Therefore, setting the second sub-segment in the second sub-layer 202 can ensure that the size of the light-transmitting hole 220 can be opened large enough, and the distribution area of ​​the light-transmitting hole 220 can be increased.

[0172] Optionally, 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 shapes of the first sub-layer 201 and the second sub-layer 202 are more compatible, thereby ensuring the performance of the isolation structure 200.

[0173] In one feasible embodiment, the width D of the first equal-width segments 153 along a direction parallel to the plane of the array substrate 11 is 1 μm to 4 μm. For example, the width D of the first equal-width segments 153 is 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., that is, the width D of the orthographic projection of the first equal-width segments 153 on the array substrate 11 is 1 μm to 4 μm. This can improve the manufacturing process difficulty caused by the first equal-width segments 153 being too small, thereby affecting the manufacturing of the display panel 1. It can also improve the distribution area of ​​the light-transmitting holes 220 and the light transmittance of the display panel 1 caused by the first equal-width segments 153 being too large.

[0174] Optionally, when the isolation structure 200 includes the first sublayer 201 and the second sublayer 202, the width of the first subsegment 201a along a direction parallel to the plane of the array substrate 11 is a first predetermined dimension D1, and the first predetermined dimension D1 is 1 μm-3 μm. For example, the first predetermined dimension D1 is 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.

[0175] Optionally, the width of the second sub-segment 202a in a direction parallel to the plane of the array substrate 11 is a second preset size D2, and the second preset size D2 is 2 μm-4 μm. For example, the second preset size D2 is 2 μm, 2.3 μm, 2.7 μm, 2.9 μm, 3 μm, 3.2 μm, 4 μm, etc.

[0176] In these optional embodiments, the width of the first sub-segment 201a is smaller, while the width of the second sub-segment 202a is larger. On the basis of ensuring that the orthographic projection of the first sub-layer 201 on the array substrate 11 is within the orthographic projection of the second sub-layer 202 on the array substrate 11, the width of the second sub-segment 202a can be as small as possible to ensure the distribution area of ​​the light-transmitting holes 220.

[0177] There are various ways to arrange the light-emitting unit 400. For example, the light-emitting unit 400 includes a first electrode 410, a light-emitting functional layer 420, and a second electrode 430-430 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. The isolation structure 200 is used to achieve the full-surface arrangement of the second electrodes 430 of multiple light-emitting units 400.

[0178] For example, optionally, the material of the first sublayer 201 includes a conductive material, and the first sublayer 201 is electrically connected to the second electrode 430 , so that the second electrodes 430 of the plurality of light-emitting units 400 can be interconnected through the first sublayer 201 to form a surface electrode.

[0179] Optionally, the material of the second sublayer 202 includes a conductive material, and the second sublayer 202 is electrically connected to the second electrode 430 , so as to increase the distribution area of ​​the conductive material and reduce the voltage drop of the second electrode 430 at different positions in the display area AA.

[0180] In one possible implementation, Figures 11 to 4 As shown, the isolation structure 200 also includes a second equal-width segment 154, which is located between adjacent isolation openings 210. The second equal-width segment 154 is set to have equal width, and the width direction of the second equal-width segment 154 is the direction in which one of the two adjacent isolation openings 210 points to the other in the orthographic projection of the array substrate 11.

[0181] In these optional embodiments, the isolation structure 200 also includes a second equal-width segment 154 located between two adjacent isolation openings 210. The second equal-width segment 154 is set to have equal width, so that the light reflection ability at different positions on the second equal-width segment 154 tends to be consistent, which can improve the display effect of the display panel 1.

[0182] The width direction of the second equal-width segment 154 is the direction in which one of the two isolation openings 210 located on its two sides points toward the other in the orthographic projections on the array substrate 11. For example, the width direction of the second equal-width segment 154 is the direction in which the geometric center of the orthographic projection of one of the two isolation openings 210 located on its two sides points toward the geometric center of the orthographic projection of the other on the array substrate 11.

[0183] There are many ways to set the widths of the first equal-width segment 153 and the second equal-width segment 154 . For example, the minimum width d1 of the first equal-width segment 153 and the minimum width d2 of the second equal-width segment 154 may be equal, or d2≤2d1.

[0184] In these optional embodiments, the width of the first equal-width segment 153 is less than or equal to the width of the second equal-width segment 154 , which can ensure that the light-transmitting hole 220 has a sufficient opening area and the light transmittance of the display panel 1 is guaranteed.

[0185] Furthermore, to ensure that light-transmitting hole 220 has a sufficiently large opening area, the width of first equal-width segment 153 is typically set to the minimum width within the process-permitted range. When the minimum width d1 of first equal-width segment 153 and the minimum width d2 of second equal-width segment 154 satisfy d2 ≤ 2d1, due to manufacturing process limitations, light-transmitting hole 220 is not suitable for formation in second equal-width segment 154 to avoid adversely affecting the functionality of isolation structure 200.

[0186] In a feasible embodiment, the second equal-width segment 154 includes a first sub-region and a second sub-region spaced apart and arranged side by side along its own width direction.

[0187] There are many ways to set the relative position relationship between the first sub-region and the second sub-region. For example, the first sub-region and the second sub-region are separated and connected to each other through the connecting portion 1310 to further reduce the distribution area of ​​the isolation structure 200 and increase the distribution area of ​​the light-transmitting hole 220.

[0188] Alternatively, the first sub-area and the second sub-area are arranged integrally, and the sum of the minimum widths of the orthographic projection of the first sub-area on the array substrate 11 and the orthographic projection of the second sub-area on the array substrate 11 is less than or equal to twice the minimum width d1 of the orthographic projection of the first equal-width segment 153 on the array substrate 11, so as to ensure that the first sub-area and the second sub-area arranged integrally have a sufficiently small width to reduce their influence on the transmittance of the display panel 1.

[0189] In one feasible embodiment, the minimum width of the orthographic projection of the connecting portion 1310 on the array substrate 11 is a third predetermined dimension D3. The third predetermined dimension D3 and the minimum width d1 of the orthographic projection of the first equal-width segment 153 on the array substrate 11 satisfy the following equation: D3 = d1. This ensures that the connecting portion 1310 has a sufficiently small width to further reduce the distribution area of ​​the isolation structure 200, increase the distribution area of ​​the light-transmitting holes 220, and improve the light transmittance of the display panel 1.

[0190] In a feasible implementation, 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 , and the first light emitting unit 401 , the second light emitting unit 402 , and the third light emitting unit 403 have different colors.

[0191] 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 .

[0192] In one possible implementation, Figure 13 and Figure 14 As shown, the isolation openings 210 include a first isolation opening 211, a second isolation opening 212, and a third isolation opening 213. The first isolation opening 211 is used to expose the first light-emitting unit 401, the second isolation opening 212 is used to expose the second light-emitting unit 402, and the third isolation opening 213 is used to expose the third light-emitting unit 403. The first isolation openings 211 and the second isolation openings 212 are alternately arranged along the second direction y to form a first opening column A1. The first direction x intersects the second direction y. The plurality of third isolation openings 213 are arranged along the second direction y to form a second opening column A2. The first opening column A1 and the second opening column A2 are alternately arranged along the first direction x.

[0193] In the above embodiment, the third light-emitting unit 403 is arranged around the first light-emitting unit 401, and the third light-emitting unit 403 is arranged around the second light-emitting unit 402. The first light-emitting unit 401 and the second light-emitting unit 402 are alternately arranged around the third light-emitting unit 403, thereby achieving a good light mixing effect and improving the light output quality of the display panel 1.

[0194] Optionally, 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 third isolation opening 213 .

[0195] In the above embodiment, the distance between the first isolation opening 211 and the third isolation opening 213 is small, making it unsuitable to provide a light-transmitting hole 220. Therefore, a second equal-width segment 154 can be provided between the first isolation opening 211 and the third isolation opening 213. Similarly, the distance between the second isolation opening 212 and the third isolation opening 213 is small, making it unsuitable to provide a light-transmitting hole 220. Therefore, a second equal-width segment 154 can be provided between the second isolation opening 212 and the third isolation opening 213.

[0196] For example, when 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 size of the second isolation opening 212 is smaller than the opening size of the first isolation opening 211. Therefore, the distance between the first isolation opening 211 and the third isolation opening 213 is smaller, and the distance between the second isolation opening 212 and the third isolation opening 213 is larger. Therefore, different settings can be used to set the second equal-width segments 154 between the first isolation opening 211, the second isolation opening 212, and the third isolation opening 213.

[0197] For example, the second equal-width segment 154 includes a first sub-region and a second sub-region located between the adjacent first isolation opening 211 and the third isolation opening 213. The first sub-region and the second sub-region are spaced apart and connected by the connecting portion 1310. The spacing between the first sub-region and the second sub-region can further reduce the distribution area of ​​the isolation structure 200, increase the distribution area of ​​the light-transmitting holes 220, and thereby improve the light transmittance.

[0198] And / or, the second equal-width segment 154 includes a first sub-region and a second sub-region located between the adjacent second isolation opening 212 and the third isolation opening 213, the first sub-region and the second sub-region are integrally arranged, and the sum of the minimum widths of the first sub-region and the second sub-region is less than or equal to 2d1, so as to ensure that the integrally arranged first sub-region and the second sub-region have a sufficiently small width to reduce their impact on the transmittance of the display panel 1.

[0199] In the above embodiment, the third isolation opening 213 includes a first sub-opening 1324 and a second sub-opening 1325 . The first sub-opening 1324 and the second sub-opening 1325 are alternately arranged along the first direction x, and adjacent first sub-openings 1324 and second sub-openings 1325 are symmetrically arranged along a symmetry axis parallel to the second direction y.

[0200] The above arrangement of the third isolation openings 213 can make the third isolation openings 213 more uniformly distributed along the circumference of the first isolation opening 211 , thereby improving the uniformity of the display panel 1 .

[0201] At the same time, the above-mentioned arrangement of the third isolation openings 213 can make the third isolation openings 213 more uniformly distributed along the circumference of the second isolation openings 212 , thereby further improving the uniformity of the display panel 1 .

[0202] In one possible implementation, Figure 13 As shown, the first isolation opening 211 is located at two opposite vertices of the virtual quadrilateral M1, and the second isolation opening 212 is located at the other two opposite vertices of the virtual quadrilateral M1. The orthographic projection of the shortest side of the virtual quadrilateral M1 on the array substrate 11 does not overlap with the orthographic projection of the light-transmitting hole 220 on the array substrate 11.

[0203] In the above embodiment, the distance between the adjacent first isolation openings 211 and the second isolation openings 212 on the shortest side of the virtual quadrilateral M1 is relatively small. Therefore, it is not appropriate to provide the light-transmitting hole 220 in order to ensure the yield of the isolation structure 200 .

[0204] The first isolation openings 211 and the second isolation openings 212 are alternately arranged along the first direction x to form a first opening row L1. In a feasible embodiment, as shown in FIG. Figures 10 to 13As shown, the light-transmitting holes 220 include a first light-transmitting hole 221 and a second light-transmitting hole 222. The first light-transmitting hole 221 is located between the first isolation opening 211 and the second isolation opening 212 in the first opening row L1, and the second light-transmitting hole 222 is located between at least a portion of the first isolation opening 211 and the second isolation opening 212 in the first opening column A1. By providing the light-transmitting holes 220 in both the first opening row L1 and the first opening column A1, the distribution area of ​​the light-transmitting holes 220 can be increased, further improving the light transmittance of the display panel 1.

[0205] In other embodiments, Figure 15 and Figure 16 As shown, the isolation structure 200 can also serve as an auxiliary cathode. For example, the second electrode 430 is a surface electrode, and the isolation structure 200 is located on the side of the second electrode 430 facing away from the array substrate 11. An insulating layer 16 can also be provided between the isolation structure 200 and the second electrode 430, and the isolation structure 200 and the second electrode 430 are connected via holes.

[0206] This application also provides another display panel 1, such as Figures 10 to 14 As shown, an array substrate 11; a light-emitting layer 40, located on one side of the array substrate 11, the light-emitting layer 40 includes a plurality of light-emitting units 400; an isolation structure 200, at least a portion of the isolation structure 200 encloses an isolation opening 210 and a light-transmitting hole 220, the isolation opening 210 is used to expose the light-emitting unit 400, and the light-transmitting hole 220 is formed between at least a portion of adjacent isolation openings 210; wherein, the isolation structure 200 includes a second equal-width segment 154 enclosing the isolation opening 210, at least the orthographic projection of the second equal-width segment 154 on the array substrate 11 is located between the orthographic projections of adjacent isolation openings 210 on the array substrate 11, the second equal-width segments 154 are set to have equal widths, and the width direction of the second equal-width segment 154 is the direction in which one of the two adjacent isolation openings 210 in the orthographic projections on the array substrate 11 points to the other.

[0207] The display panel 1 provided herein 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, which are configured to emit light to achieve the display function of the display panel 1. The isolation structure 200 also includes a second equal-width segment 154 located between two adjacent isolation openings 210. The second equal-width segments 154 are configured with equal widths, so that the light reflectivity at different locations on the second equal-width segments 154 is consistent, thereby improving the display effect of the display panel 1.

[0208] In some optional embodiments, the isolation structure 200 further includes a first equal-width segment 153, which is located between the adjacent light-transmitting holes 220 and the isolation opening 210. The minimum width of the orthographic projection of the first equal-width segment 153 on the array substrate 11 is d1, and the minimum width of the orthographic projection of the second equal-width segment 154 on the array substrate 11 is d2, where d2≤2d1.

[0209] In these optional embodiments, the width of the first equal-width segment 153 is less than or equal to the width of the second equal-width segment 154 , which can ensure that the light-transmitting hole 220 has a sufficient opening area and the light transmittance of the display panel 1 is guaranteed.

[0210] In addition, in order 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 allowable range. When 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, due to the limitations of the preparation process, it is not suitable to form a light-transmitting hole 220 on the second equal-width segment 154 to avoid adverse effects on the function of the isolation structure 200.

[0211] In some optional embodiments, the second equal-width segment 154 includes a first sub-region and a second sub-region spaced apart along a direction pointing from one of the two adjacent isolation openings 210 to the other. The first sub-region and the second sub-region are spaced apart and connected to each other through a connecting portion 1310 to further reduce the distribution area of ​​the isolation structure 200 and increase the distribution area of ​​the light-transmitting hole 220.

[0212] Alternatively, the first sub-region and the second sub-region are integrally provided, and the sum of the minimum widths of the orthographic projection of the first sub-region on the array substrate 11 and the orthographic projection of the second sub-region on the array substrate 11 is less than or equal to 2d1. This ensures that the integrally provided first sub-region and the second sub-region have sufficiently small widths, thereby reducing their impact on the transmittance of the display panel 1.

[0213] In some optional embodiments, the second equal-width segment 154 includes a first sub-region and a second sub-region spaced apart from each other and connected by a connecting portion 1310. The minimum width d3 of the orthographic projection of the connecting portion 1310 on the array substrate 11 and the minimum width d1 of the orthographic projection of the first equal-width segment 153 on the array substrate 11 satisfy the following: d3 = d1. The connecting portion 1310 has a sufficiently small width to further reduce the distribution area of ​​the isolation structure 200, increase the distribution area of ​​the light-transmitting holes 220, and improve the light transmittance of the display panel 1.

[0214] In this embodiment, the configuration of the light emitting unit 400 and the isolation structure 200 is as described above and will not be repeated here. The display panel 1 of this embodiment and the display panel 1 in any of the above embodiments can be cross-referenced to each other.

[0215] This application also provides another display panel 1, such as Figures 10 to 14 As shown, the display panel 1 has a first display area and a second display area disposed around at least a portion of the first display area. The display panel 1 includes: an array substrate 11; a light-emitting layer 40 located on one side of the array substrate 11, the light-emitting layer 40 including a plurality of light-emitting units 400; an isolation structure 200, at least a portion of which encloses an isolation opening 210 and a light-transmitting hole 220 located in the first display area. The isolation opening 210 is used to expose the light-emitting units 400, and the light-transmitting hole 220 is formed between at least a portion of adjacent isolation openings 210. In which, the isolation structure 200 includes a first equal-width segment 153 enclosing the light-transmitting hole 220, and at least the orthographic projection of the first equal-width segment 153 on the array substrate 11 is located between the orthographic projection of the adjacent isolation opening 210 on the array substrate 11 and the orthographic projection of the light-transmitting hole 220 on the array substrate 11. The first equal-width segments 153 are set to have equal widths, and the width direction of the first equal-width segments 153 is the direction in which one of the orthographic projections of the light-transmitting hole 220 on the array substrate 11 and the orthographic projection of the isolation opening 210 on the array substrate 11 points to the other.

[0216] In the embodiment of the present application, light-transmitting holes 220 are disposed in the first display area, thereby improving the light transmittance of the first display area and enabling under-screen integration of the photosensitive module in the first display area. By disposing first equal-width segments 153 within the first display area, and by setting the first equal-width segments 153 to have equal widths, i.e., by setting the isolation structure 200 between the light-transmitting holes 220 and the isolation opening 210 to have equal widths, the area of ​​the light-transmitting holes 220 is maximized, while maintaining a constant area for the isolation opening 210 and ensuring a manufacturing yield, thereby increasing the distribution area of ​​the light-transmitting holes 220 and improving the light transmittance of the display panel 1.

[0217] In this embodiment, the configuration of the light emitting unit 400 and the isolation structure 200 is as described above and will not be repeated here. The display panel 1 of this embodiment and the display panel 1 in any of the above embodiments can be cross-referenced to each other.

[0218] The present application also provides a display device 2, such as Figure 17 As shown, it includes any one of the display panels 1 provided in the above embodiments of the present application.

[0219] The display device 2 provided in the present application also includes a photosensitive module, which is integrated into the display panel 1 or located on the side of the array substrate 11 away from the light-emitting layer 40. The transmittance of the display panel 1 is improved, so that the photosensitive film group can better receive light, thereby improving the working yield of the photosensitive film group.

[0220] In an embodiment of the present application, the display panel includes an array substrate 100 and an isolation structure 200, and the isolation structure 200 encloses an isolation opening 210 and a light-transmitting hole 220. The isolation opening 210 is used to set a light-emitting unit 400 to improve the mutual crosstalk between adjacent light-emitting units 400 and realize the light-emitting display of the display panel. The array substrate 100 includes a substrate 120 and a metal structure 110 arranged on the substrate 120, and the metal structure 110 can be used to drive the light-emitting unit 400 to emit light. The light-transmitting hole 220 is used to improve the transmittance of the display panel and facilitate the under-screen integration of the photosensitive module. The orthographic projection of the light-transmitting hole 220 on the substrate 120 and the orthographic projection of the metal structure 110 on the substrate 120 are at least partially staggered, which can improve the influence of the metal structure 110 on the transmittance of the light-transmitting hole 220. Typically, the distribution shapes of the metal structures 110 corresponding to the same isolation opening 210 in the substrate are different, and the orthographic projection shapes 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. This facilitates the user to reasonably set the shapes of the first light-transmitting hole 221 and the second light-transmitting hole 222 according to the distribution of the metal structures 110 in the substrate, so that the sizes of the first light-transmitting hole 221 and the second light-transmitting hole 222 are more suitable for the distribution shape of the metal structures 110 in the substrate. This maximizes the distribution area of ​​the light-transmitting holes 220 and improves the signal interference problem caused by the metal structure 110 being exposed through the light-transmitting hole 220, thereby improving the performance of the display panel.

[0221] The display panel of the present embodiment and any of the above embodiments may be cross-referenced. For example, the width of at least some of the first light-transmitting holes 221 in the first direction X is greater than the width of the second light-transmitting holes 222 in the first direction X, so that the sizes of the first light-transmitting holes 221 and the second light-transmitting holes 222 are more adapted to the distribution shape of the metal structure 110 in the substrate.

[0222] Optionally, the first light-transmitting holes 221 and the second light-transmitting holes 222 have the same extension length in the second direction Y, so as to simplify the distribution shape of the light-transmitting holes 220 and facilitate the preparation and molding of the light-transmitting holes 220 .

[0223] Optionally, the light-transmitting hole 220 has the above-mentioned first side 230, and the isolation opening 210 has the above-mentioned second side 240. The configuration of the first side 230 and the second side 240 is as described above and will not be repeated here. The light-transmitting hole 220 may also include the above-mentioned first straight edge 220a. Figures 1 to 17As shown, an embodiment of the second aspect of the present application further provides a display device, comprising the display panel 10 of any of the above-mentioned embodiments of the first aspect. Since the display device provided by the embodiment of the second aspect of the present application comprises the display panel 10 of any of the above-mentioned embodiments of the first aspect, the display device provided by the embodiment of the second aspect of the present application has the beneficial effects of the display panel 10 of any of the above-mentioned embodiments of the first aspect, which will not be repeated here.

[0224] The display device in the embodiments of the present application includes but is not limited to mobile phones, personal digital assistants (PDAs), tablet computers, e-books, televisions, access control systems, smart landline phones, consoles, and other devices with display functions.

[0225] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and components may be substituted with equivalents without departing from the scope of the present application. In particular, the various technical features described in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
