[0014] To better understand the present application, the display panel and display device in the embodiments of the present application will be described in detail below in connection with FIGS. 1 to 17.

[0015] The related technical solutions of Patent CN118251982A, 202410864269.8, PCT / CN2024 / 098407, PCT / CN2024 / 102783, PCT / CN2024 / 098217, PCT / CN2024 / 100935, PCT / CN2024 / 102785, PCT / CN2024 / 099419, PCT / CN2024 / 099072, CN116685174A are for reference.

[0016] FIG. 1 is a structural schematic diagram of a display panel according to an embodiment of the present application, FIG. 2 is an enlarged structural schematic diagram of a part of FIG. 1, and FIG. 3 is a cross-sectional view of the A-A position in FIG. 2 according to an example.

[0017] As shown in FIGS. 1 to 3, the embodiment of the present application provides a display panel including an array substrate 100, an isolation structure 200, and a light-emitting unit 400. The array substrate 100 includes a substrate 120 and a metal structure 110 provided on the substrate 120. The isolation structure 200 is provided on one side of the array substrate 100, enclosing and closing to form a plurality of isolation openings 210 and light-transmitting holes 220. 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 provided with at least partial misalignment. The light-emitting unit 400 is provided corresponding to the isolation opening 210. Among them, the orthographic projection of the light-transmitting hole 220 on the substrate 120 includes a recess 220d.

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

[0019] In embodiments of the present invention, the display panel comprises an array substrate 100 and an isolation structure 200, the isolation structure 200 enclosing and closing to form an isolation opening 210 and a light-transmitting hole 220. The isolation opening 210 is used to house at least some light-emitting units 400, thereby improving mutual crosstalk between adjacent light-emitting units 400 and enabling the display panel to emit light. The array substrate 100 comprises a substrate 120 and a metal structure 110 provided on the substrate 120, the metal structure 110 being usable to drive the light emission of the light-emitting units 400. The light-transmitting hole 220 is used to increase the light transmittance of the display panel and facilitate under-display integration of a light-sensing 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 offset, thereby improving the influence of the metal structure 110 on the light transmittance of the light-transmitting hole 220. At least one light-transmitting hole 220 is provided with a recessed portion 220d, and by reducing the distance between the orthographic projection of the recessed portion 220d on the substrate 120 and the orthographic projection of the isolation aperture 210 on the substrate 120, the distribution area of ​​the light-transmitting holes 220 can be increased as much as possible, and the signal interference problem caused by exposure of many metal structures 110 from the light-transmitting holes 220 can be improved, thereby improving the usability of the display panel.

[0020] Preferably, of at least one group of adjacent light-transmitting holes 220 and isolation openings 210, the one oriented from the center of one to the center of the other is the preset direction, for example, the preset direction is the X direction in Figure 2, and the minimum distance between the edge of the recess 220d and the edge of the isolation opening 210 in the preset direction is greater than or equal to the preset distance h. This makes it possible to maximize the distribution area of ​​the light-transmitting holes 220 by reducing the distance between the recess 220d and the isolation opening 210.

[0021] Preferably, along the preset direction, in at least one group of adjacent light-transmitting holes 220 and isolation openings 210, the orthographic projection of the isolation opening 210 on the substrate 120 includes a projection 210a provided corresponding to the recess 220d. The adjacent isolation openings 210 are adapted to the shape of the light-transmitting holes 220 to maximize the distribution area of ​​the light-transmitting holes 220.

[0022] Preferably, the shapes of at least a portion of the protruding portion 210a and at least a portion of the recessed portion 220d are conformed. This maximizes the distribution area of ​​the light-transmitting holes 220.

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

[0024] In these preferred embodiments, the distribution area of ​​the metal structure 110 corresponding to the periphery of the same isolation opening 210 in the array substrate 11 is typically different, and the orthographic areas of the first light-transmitting hole 221 and the second light-transmitting hole 222 in the substrate are different. Based on the distribution of the metal structure 110 in the substrate, the user can reasonably set the dimensions of the first light-transmitting hole 221 and the second light-transmitting hole 222 to better match the distribution figure of the metal structure 110 in the substrate. This maximizes the distribution area of ​​the light-transmitting holes 220.

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

[0026] The statement that 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 provided with at least a partial misalignment means that the orthographic projection of the same light-transmitting holes 220 on the substrate and the orthographic projection of the metal structure 110 on the substrate 120 are provided with at least a partial misalignment, and that the metal structure 110 does not correspond to at least a portion of the same light-transmitting holes 220. Preferably, the orthographic projection of the light-transmitting holes 220 on the substrate 120 is 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 holes 220 on the substrate 120 may overlap with the orthographic projection of the metal structure 110 on the substrate 120, while the orthographic projection of another portion of the light-transmitting holes 220 on the substrate 120 is located outside the orthographic projection of the metal structure 110 on the substrate 120.

[0027] Preferably, the display panel further comprises a pixel definition layer 300, which is provided on the array substrate 100 and includes a pixel limiting portion 310 and a pixel aperture 320 opened in the pixel limiting portion 310, the pixel aperture 320 communicating with an isolation aperture 210, and the light-emitting unit 400 is provided corresponding to the pixel aperture, with a part of its structure located within the pixel aperture 320. The isolation structure 200 may be provided on the side of the pixel limiting portion 310 that is separated from the array substrate 100, or the pixel limiting portion 310 may be provided with a retractable aperture, and the isolation structure 200 may be located within the retractable aperture and directly contact and connect to the array substrate 100. Preferably, the material of the pixel definition layer 300 may be an inorganic material, which allows for an appropriate reduction in the thickness of the pixel definition layer 300 and an overall reduction in the thickness of the display panel 10.

[0028] Preferably, the distance between at least a portion of the orthographic edges of the light-transmitting holes 220 on the array substrate 100 and at least a portion of the orthographic edges of the isolation apertures 210 on the array substrate 100 is greater than or equal to the preset distance h. This can improve the mutual influence between the isolation apertures 210 and the light-transmitting holes 220.

[0029] There are several ranges for the preset distance h of the light transmission hole 220. The preset distance h may be 3 μm to 4 μm, for example, 3 μm, 3.2 μm, 3.5 μm, 3.8 μm, 4 μm, etc. This improves the situation where the preset distance h is too large and affects the aperture area of ​​the light transmission hole 220, or where the preset distance h is too small and affects the positional stability of the light transmission hole 220 of the isolation aperture 210. The preset distance h is not fixed in the actual process fluctuations, and even if vertical errors occur, they remain within the protected range.

[0030] There are several installation methods for the isolation structure 200. As shown in Figure 3, the isolation structure 200 may include a first sublayer 201 and a second sublayer 202 that are stacked in a direction away from the array substrate 100. The orthographic projection of the first sublayer 201 on the array substrate 100 lies within the orthographic projection of the second sublayer 202 on the array substrate 100. That is, the second sublayer 202 is provided protruding from the side of the first sublayer 201. The dimensions of the first sublayer 201 are smaller than the dimensions of the second sublayer 202. This allows for the formation of an inward recess structure on the side of the second sublayer 202 facing the substrate 120. When the light-emitting unit 400 is subsequently manufactured, the light-emitting material is blocked by the isolation structure 200, allowing the light-emitting units 400 corresponding to the isolation openings 210 to be formed independently of each other.

[0031] Preferably, as shown in Figure 4, the isolation structure 200 may further include a third sublayer 203 located on the side of the first sublayer 201 facing the array substrate 100, such that the orthographic projection of the first sublayer 201 on the array substrate 100 lies within the orthographic projection of the third sublayer 203 on the array substrate 100, i.e., the dimensions of the first sublayer 201 are smaller than the dimensions of the third sublayer 203. During the manufacturing process of the first sublayer 201, the third sublayer 203 can provide protection to the film layer located on the side of the isolation structure 200 facing the array substrate 100.

[0032] Preferably, the light-emitting unit 400 comprises a first electrode 410, a light-emitting functional layer 420, and a second electrode 430, which are stacked in a direction away from the array substrate 100. The first electrode 410 may be located on the array substrate 100, or it may be located within the pixel aperture 320, or its edge may be enclosed by the pixel limiting portion 310 and exposed from the pixel aperture 320. The light-emitting functional layer 420 is located within the pixel aperture 320. Preferably, the material of the isolation structure 200 may include a conductive material, and the second electrode 430 and the isolation structure 200 are superimposed and connected to each other, so that each second electrode 430 can be connected to each other by the isolation structure 200 to become a surface electrode.

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

[0034] In these preferred 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. Since 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, the distance between the first side 230 and the second side 240 is small, thereby maximizing the opening size of the light-transmitting hole 220.

[0035] Preferably, as shown in Figure 7, the shapes of the first side 230 and the second side 240 are compatible with each other. This maximizes the distribution area of ​​the light-transmitting holes 220 and improves the interaction between the light-transmitting holes 220 and the isolation opening 210.

[0036] Preferably, the first side 230 and the second side 240 are provided at equal intervals. The first side 230 and the second side 240 are provided at equal intervals within the process tolerance range. For example, the second side 240 is an arc-shaped side that protrudes in the direction away from the center of the isolation opening 210, and the first side 230 is an arc-shaped side that is recessed in the direction away from the center of the isolation opening 210 and recessed toward the interior of the first light-transmitting hole 221, thereby providing equal intervals between the first side 230 and the second side 240.

[0037] In these preferred embodiments, the first side 230 and the second side 240 are provided at equal intervals, ensuring that the light-transmitting holes 220 have a sufficiently large distribution area, and improving the influence of the light-transmitting holes 220 on the isolation opening 210.

[0038] Preferably, the first side 230 and the second side 240 are arc-shaped. Preferably, in order to improve the diffraction phenomenon between light-emitting units 400 of different colors, the orthographic projection figure of the isolation aperture 210 on the array substrate 100 is circular, elliptical, etc., and the embodiment of the present application will be described using the example that the orthographic projection shape of the isolation aperture 210 on the array substrate 100 is elliptical, in which case the second side 240 is part of the ellipse. The first side 230 may also be part of the ellipse, thereby both the first side 230 and the second side 240 are arc-shaped, and the distance between the first side 230 and the second side 240 may be equal.

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

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

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

[0042] Preferably, the second side 240 includes a third sub-edge 241 toward the first sub-edge 231 and a fourth sub-edge 242 toward the second sub-edge 232, and the distance between the first sub-edge 231 and the third sub-edge 241 may be equal to the distance between the second sub-edge 232 and the fourth sub-edge 242. Alternatively, the distance between the first sub-edge 231 and the third sub-edge 241 may be smaller than the distance between the second sub-edge 232 and the fourth sub-edge 242, thereby allowing the first light-transmitting holes 221 and the second light-transmitting holes 222 to better match the distribution pattern of the metal structure 110 within the array substrate 100.

[0043] The shape of the light-transmitting hole 220 may be an inwardly concave polygon overall, with one of its sides being the first side 230.

[0044] Preferably, the inner wall of the light-transmitting hole 220 has a recessed portion 220d that is recessed in a direction away from the isolation opening 210, and the first side 230 is provided in the recessed portion 220d. In these preferred embodiments, the objective of having the first side 230 and the second side 240 at equal intervals is satisfied by providing the recessed portion 220d in the light-transmitting hole 220 and providing the first side 230 in the recessed portion 220d in order to accommodate a circular or elliptical isolation opening 210.

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

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

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

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

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

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

[0051] Preferably, the first right edge 220a has a first midpoint line P1 extending along a first direction X, and the first side edge 230 is provided symmetrically with respect to the first midpoint line P1, thereby further simplifying the shape of the light-transmitting hole 220. The first midpoint line P1 is formed by passing through the midpoint of the first right edge 220a in a second direction Y and extending along the first direction X. Preferably, when the first right edge 220a is provided in the first light-transmitting hole 221, the first sub-edge 231 is provided symmetrically with respect to the first midpoint line P1, or when the first right edge 220a is provided in the second light-transmitting hole 222, the second sub-edge 232 is provided symmetrically with respect to the first midpoint line P1.

The distribution area of ​​the first isolation opening 211 is usually large, and by positioning the first side 230 on the side of the light-transmitting hole 220 facing the first isolation opening 211, the mutual interference of positions between the light-transmitting hole 220 and the first isolation opening 211 can be improved.

[0053] Preferably, as shown in Figure 8, at least one light-transmitting hole 220 has at least two recesses 220d that face at least two isolation openings 210 located on its periphery, each recess 220d having a first side 230, and a plurality of isolation openings 210 are arranged around the periphery of at least one light-transmitting hole 220, and at least two of the plurality of isolation openings 210 have projections 210a that face the same light-transmitting hole 220, each projection 210a having a second side 240, and the shapes of the first side 230 and the corresponding second side 240 are compatible with each other.

[0054] Having at least one light-transmitting hole 220 having at least two recesses 220d that extend toward at least two isolation openings 210 located on its periphery means that at least one light-transmitting hole 220 has at least two recesses 220d, and at least two isolation openings 210 are provided on the periphery of the light-transmitting hole 220, and the recesses 220d are provided corresponding to the isolation openings 210.

[0055] In these preferred embodiments, multiple isolation openings 210 may be provided on the periphery of the same light-transmitting hole 220, and by providing multiple recesses 220d in the same light-transmitting hole 220 to match the protrusions 210a of at least two of the multiple isolation openings 210 located on the periphery of the same light-transmitting hole 220, the shape of the light-transmitting hole 220 can be made to better match the shape of the multiple isolation openings 210 on the periphery, thereby further increasing the distribution area of ​​the light-transmitting hole 220 and increasing the light transmittance.

[0056] Preferably, as shown in Figure 8, the light-transmitting hole 220 has two first sides 230, and the two isolation openings 210 are provided around the same light-transmitting hole 220 and each has a second side 240.

[0057] Preferably, when the shape of the isolation opening 210 is elliptical as shown in Figure 2, the light-transmitting hole 220 may have four first sides 230, and the four isolation openings 210 are arranged around the same light-transmitting hole 220 and each has a second side 240. That is, one light-transmitting hole 220 may have four recesses 220d, each recess 220d having a first side 230 and facing the four isolation openings 210, and each of the four isolation openings 210 is provided with a protrusion 210a and a second side 240, further increasing the distribution area of ​​the light-transmitting hole 220 and increasing the light transmittance.

[0058] Preferably, the first side 230 includes at least one of a straight line segment and a curved line segment. This allows the shape of the light-transmitting hole 220 to better match the shape of the multiple isolation openings 210 located on its periphery, further increasing the distribution area of ​​the light-transmitting hole 220 and improving the light transmittance.

[0059] In some preferred embodiments, as shown in Figures 2 and 5, the isolation opening 210 comprises a first isolation opening 211 and a second isolation opening 212, the first isolation opening 211 and the second isolation opening 212 being alternately arranged along a first direction X to form a first opening group H1, and the first light-transmitting holes 221 and the second light-transmitting holes 222 being alternately arranged along the first direction X, so that each adjacent first isolation opening 211 and second isolation opening 212 is provided with either a first light-transmitting hole 221 or a second light-transmitting hole 222, and a recessed portion 220d is provided in at least one of the first light-transmitting holes 220 and the second light-transmitting holes 220.

[0060] In these preferred embodiments, the first isolation opening 211 and the second isolation opening 212 are arranged alternately along the first direction X, and the first light-transmitting holes 221 and the second light-transmitting holes 222 are arranged alternately along the first direction X, so that the first light-transmitting holes 221 and the second light-transmitting holes 222 are provided on both sides of either one of the first isolation openings 211 or the second isolation opening 212, thereby increasing the distribution area of ​​the light-transmitting holes 220 and improving the light transmittance of the display panel.

[0061] There are several ways to install the light-emitting unit 400. Preferably, 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, each with a different color. The first light-emitting unit 400 may be provided corresponding to the first isolation opening 211, and the second light-emitting unit 400 may be provided 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 provided corresponding to the third isolation opening 213.

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

[0063] In these preferred embodiments, the installation position of the metal structure 110 is perfectly offset from the first light-transmitting holes 221 and the second light-transmitting holes 222, ensuring the light transmittance in the areas where the first light-transmitting holes 221 and the second light-transmitting holes 222 are located, thereby increasing the light transmittance of the display panel.

[0064] 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 electrode G, a signal line, and a capacitor plate C. This ensures that the installation position of at least one of the gate electrode G, the signal line, and the capacitor plate C is perfectly offset from the first light-transmitting hole 221 and the second light-transmitting hole 222, guaranteeing the light transmittance in the area where the first light-transmitting hole 221 and the second light-transmitting hole 222 are located, thereby increasing the light transmittance of the display panel. The signal line may be at least one of a scanning signal line and a power signal line.

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

[0066] In these preferred embodiments, the drive circuit T comprises metal oxide transistors and low-temperature polysilicon transistors of different types, the gate electrode G comprises a first gate electrode and a second gate electrode located on different types of transistors, and the metal structure 110 comprises at least one of the first gate electrode and the second gate electrode, thereby ensuring that the installation position of at least one of the first gate electrode and the second gate electrode is perfectly offset from the first light-transmitting hole 221 and the second light-transmitting hole 222, thereby ensuring the light transmittance of the region where the first light-transmitting hole 221 and the second light-transmitting hole 222 are located, and increasing the light transmittance of the display panel.

[0067] The metal oxide transistor may also be an indium gallium zinc oxide transistor. Preferably, the drive circuit T may include a drive transistor which is either a metal oxide transistor or a low-temperature polysilicon transistor, and a switching transistor which is the other of the metal oxide transistor or low-temperature polysilicon transistor, so that the gate electrodes of the drive transistor and / or switching transistor are completely offset from the first light-transmitting hole 221 and the second light-transmitting hole 222. Preferably, the drive circuit may further include a threshold compensation transistor, a reset transistor, a light emission control transistor, etc., and the orthographic projections of the gate electrodes of these different types of transistors on the substrate 120 may all be located 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 increasing the light transmittance of the display panel.

[0068] Referring to the Preamble, the isolation opening 210 may further comprise a third isolation opening 213, and a plurality of third isolation openings 213 are spaced apart along a first direction X to form a second aperture group H2, and as shown in Figure 6, the light transmission hole 220 further comprises a third light transmission hole 223 located between at least two adjacent third isolation openings 213. By providing the additional third light transmission hole 223 located between two adjacent third isolation openings 213 in the second aperture group H2, the total distribution area of ​​the light transmission hole 220 can be further increased, thereby increasing the light transmittance of the display panel.

[0069] Preferably, the orthographic area of ​​the first isolation opening 211 on the array substrate 100 is larger than the orthographic area of ​​the second isolation opening 212 on the array substrate 100, and the orthographic area of ​​the second isolation opening 212 on the array substrate 100 is larger than the orthographic area of ​​the third isolation opening 213 on the array substrate 100. That is, the distribution area of ​​the third isolation opening 213 for housing the blue light-emitting unit 400 is maximized, increasing the distribution area of ​​the blue light-emitting unit 400 and extending the service life of the blue light-emitting unit 400.

[0070] Preferably, two second isolation openings 212 and two first isolation openings 211 are provided on the periphery of the third isolation opening 213, and the two first isolation openings 211 and the two second isolation openings 212 are arranged alternately on the periphery of the third isolation opening 213. As a result, two second light-emitting units 400 and two first light-emitting units 400 are provided on the periphery of the third light-emitting unit 400, and the two first light-emitting units 400 and the two second light-emitting units 400 are arranged alternately on the periphery of the third light-emitting unit 400. This reduces the distance between the third light-emitting unit 400 and the first and second light-emitting units 400, thereby enhancing the display effect of the display panel.

[0071] Preferably, the orthographic area of ​​the third light-transmitting hole 223 on the array substrate 100 is smaller than the orthographic area of ​​the first light-transmitting hole 221 or the second light-transmitting hole 222 on the array substrate 100, thereby allowing the shape and dimensions of the third light-transmitting hole 223 to be better suited to the third isolation opening 213.

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

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

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

[0075] In these preferred embodiments, the first light-transmitting holes 221, the second light-transmitting holes 222, and the third light-transmitting holes 223 are also provided on the periphery of the second isolation opening 212, further increasing the distribution area of ​​the light-transmitting holes 220 and making the distribution of the light-transmitting holes 220 more uniform.

[0076] Preferably, 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, and not on the other side in the third direction. In this way, of two adjacent third isolation openings 213 in two groups, a third light-transmitting hole 223 is provided between adjacent third isolation openings 213 in one group, while a third light-transmitting hole 223 is not provided between adjacent third isolation openings 213 in the other group.

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

[0078] In some preferred embodiments, the second aperture group H2 further comprises a first gap Q and a second gap Q2 located between two adjacent third isolation apertures 213, wherein the first gap Q and the second gap Q2 are arranged alternately along a first direction X, and the third light-transmitting hole 223 is located in the first gap Q.

[0079] In these preferred embodiments, the third light-transmitting hole 223 is provided in the first gap Q, but not in the second gap Q2, allowing it to be retracted for the metal structure 110, thereby reducing the influence of ambient light on the metal structure 110 located in the second gap Q2.

[0080] Preferably, conductive wires are further provided in the substrate 120, and the wiring density of conductive wires at the location of the first gap Q is smaller than the wiring density of conductive wires in the region where the second gap Q2 is located. By providing a third light-transmitting hole 223 in the first gap Q where the wiring density is relatively small, the influence of ambient light on the conductive wires can also be improved, provided that the light transmittance is increased.

[0081] Preferably, as shown in Figure 6, the orthographic projection of at least one conductive wire on the substrate 120 and the orthographic projection of the third light-transmitting hole 223 on the substrate 120 overlap at least partially. That is, a conductive wire may be provided in the third light-transmitting hole 223, for example, by passing the conductive wire through the third light-transmitting hole 223, thereby increasing the light transmittance and simplifying the installation method of the third light-transmitting hole 223.

[0082] Preferably, the conductive wire includes a power signal line, and the orthographic projection of the power signal line on the substrate 120 and the orthographic projection of the third light transmission hole 223 on the substrate 120 overlap at least partially. Preferably, the power signal line includes at least one of a drive power supply voltage signal line VDD and a voltage reference signal line.

[0083] There are several ways to set the orthographic projection shape of the third light-transmitting hole 223 on the array substrate 100. For example, the orthographic projection of the third light-transmitting hole 223 on the array substrate 100 can be formed as a polygon, circle, ellipse, or the like.

[0084] Preferably, as shown in Figures 6 to 8, the shape of the third light-transmitting hole 223 and the shapes of the third isolation openings 213 located on either side thereof are compatible with each other. For example, in some preferred embodiments, the third light-transmitting hole 223 has 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, with equal spacing between the third side 250 and the fourth side 260.

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

[0086] In these preferred embodiments, the third side 250 and the fourth side 260 are equally spaced, which allows the shape of the third light-transmitting hole 223 to better match the shape of the third isolation aperture 213, maximizing the distribution area of ​​the third light-transmitting hole 223 and increasing 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 hole 223 has a sufficiently large distribution area, thereby improving mutual interference and influence between the third light-transmitting hole 223 and the third isolation aperture 213.

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

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

[0089] In these preferred embodiments, the third light-transmitting hole 223 is more conforming to the shape of the third isolation openings 213 located on either side of it, since the distance from the edges of the third isolation openings 213 located on either side of it to the edges of the third isolation openings 213 is equal in all cases.

[0090] Preferably, the third light-transmitting hole 223 has a second median line P2 extending along the second direction Y, and the fifth sub-edge 251 and the sixth sub-edge 252 are provided symmetrically with respect to the second median line P2. Preferably, the second median line P2 passes through the center of the third light-transmitting hole 223 in the first direction X and is formed by extending along the second direction Y. Since the fifth sub-edge 251 and the sixth sub-edge 252 are symmetrical with respect to the second median line P2, the shape of the third light-transmitting hole 223 can be simplified and the manufacturing and molding of the third light-transmitting hole 223 can be facilitated.

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

[0092] In these preferred embodiments, the distribution area of ​​the third light-transmitting holes 223 can be appropriately increased by setting the third light-transmitting holes 223 to first segments 223a and second segments 223b with different widths, so that the shape of the third light-transmitting holes 223 is better matched to the shape of the gap between the two adjacent third isolation openings 213.

[0093] 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 are inclined along the direction in which the two third isolation openings 213 move closer to each other in the direction from the first segment 223a to the second segment 223b. As a result, the gap width at the location of the first segment 223a is larger than the gap width at the location of the second segment 223b. Therefore, by setting the width of the first segment 223a to be relatively large, the distribution area of ​​the third light-transmitting hole 223 can be appropriately increased, and mutual influence between the third light-transmitting hole 223 and the third isolation openings 213 is less likely to occur. For example, the fact that the third isolation openings 213 are elliptical and the two third isolation openings 213 are inclined along the direction in which they move closer to each other can be understood as the straight lines on which the major axes of the two third isolation openings 213 are located intersect.

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

[0095] Preferably, the width of the second segment 223b in the first direction X gradually decreases along the direction away from the first segment 223a. This allows the shape of the second segment 223b to better conform to the gap shape at its location.

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

[0097] In some preferred embodiments, in the first light-transmitting hole 221 and the first and second isolation openings 211 and 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 opening 211 and the second isolation opening 212 are not provided symmetrically with respect to the first light-transmitting hole 221, and therefore, by providing the first light-transmitting hole 221 in a region of the metal structure 110 with relatively low density, light transmittance can be guaranteed.

[0098] In some preferred embodiments, the distance from the first isolation opening 211 to the second light-transmitting hole 222 and the distance from the second isolation opening 212 to the second light-transmitting hole 222 are not equal. That is, the first isolation opening 211 and the second isolation opening 212 are not provided symmetrically with respect to the second light-transmitting hole 222, and therefore, by providing the second light-transmitting hole 222 in a region of the metal structure 110 where the density is relatively low, light transmittance can be guaranteed.

[0099] In some preferred embodiments, the distance from the first light-transmitting hole 221 to the first light-transmitting hole 221 to the first light-transmitting hole 222 to the first light-transmitting hole 211 is not equal to the distance from the second light-transmitting hole 222 to the first light-transmitting hole 211. That is, the first light-transmitting hole 221 and the second light-transmitting hole 222 are not provided symmetrically with respect to the first light-transmitting hole 211. Therefore, by providing the first light-transmitting hole 221 and the second light-transmitting hole 222 in a region of the metal structure 110 where the density is relatively low, light transmittance can be guaranteed.

[0100] In some preferred embodiments, the distance from the first light-transmitting hole 221 to the second light-transmitting hole 222 to the second light-transmitting hole 222 is not equal to the distance from the second light-transmitting hole 222 to the second light-transmitting hole 212, with respect to the second isolation opening 212 and the first light-transmitting holes 221 and the second light-transmitting hole 222 located on either side thereof. That is, the first light-transmitting hole 221 and the second light-transmitting hole 222 are not provided symmetrically with respect to the second isolation opening 212, and therefore, by providing the first light-transmitting hole 221 and the second light-transmitting hole 222 in a region of the metal structure 110 where the density is relatively low, light transmittance can be guaranteed.

[0101] In some preferred embodiments, the orthographic area of ​​the first light-transmitting hole 220 on the substrate 120 is larger than the orthographic 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 with different areas, each light-transmitting hole 220 can be better fitted to gaps of different dimensions, and the overall distribution area of ​​the light-transmitting holes 220 can be further increased.

[0102] In some other preferred embodiments, the first light-transmitting holes 221 and the second light-transmitting holes 222 are located on opposite sides of the same isolation opening 210 in a first direction X, thereby spacing the first light-transmitting holes 221 and the second light-transmitting holes 222 along the first direction X, which simplifies the arrangement structure of the light-transmitting holes 220.

[0103] Preferably, referring together to Figures 2 and 7, the lengths of the first light-transmitting hole 221 and the second light-transmitting hole 222 in the second direction Y are the same. This simplifies the shapes of the first light-transmitting hole 221 and the second light-transmitting hole 222 and facilitates the manufacturing and molding of the first light-transmitting hole 221 and the second light-transmitting hole 222. For example, the length of the first light-transmitting hole 221 in the second direction Y is b1, and the length of the second light-transmitting hole 222 in the second direction Y is b2, and b1 and b2 are equal.

[0104] Preferably, the width of at least some of the first light-transmitting holes 221 in the first direction X is greater than the width of the second light-transmitting holes 222 in the first direction X. This results in different distribution areas for the first light-transmitting holes 221 and the second light-transmitting holes 222, and the shapes of the first light-transmitting holes 221 and the second light-transmitting holes 222 are more likely to conform to the distribution pattern of the metal structure 110 within 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, with W1 being greater than W2.

[0105] There are several ways in which the shapes of the first light-transmitting holes 221 and the second light-transmitting holes 222 can be installed. For example, the shapes of the first light-transmitting holes 221 and the second light-transmitting holes 222 may be polygonal, circular, elliptical, etc., and the first light-transmitting holes 221 and the second light-transmitting holes 222 may have irregular shapes.

[0106] As described in the preamble, as shown in Figure 3, the display panel further comprises a first sealing layer 500, the first sealing layer 500 comprising sealing portions 510 that seal each isolation opening 210 at intervals from each other, a positional retraction gap is formed between adjacent sealing portions 510, and the orthographic projection of the positional retraction gap on the substrate 120 and the orthographic projection of the light transmission holes 220 on the substrate 120 overlap at least partially.

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

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

[0109] Preferably, the orthographic projection of the light-transmitting hole 220 on the substrate 120 lies within the orthographic projection of the positional retraction gap on the substrate 120, that is, the light-transmitting hole 220 and the sealing portion 510 are completely misaligned, thereby further increasing the light transmittance in the region where the light-transmitting hole 220 is located.

[0110] Preferably, the material of the first sealing layer 500 can protect the inorganic material. As a result, the first sealing layer 500 has good density.

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

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

[0113] Preferably, when the pixel definition layer 300 comprises a pixel limiting portion 310 and a pixel aperture 320 communicating with the isolation aperture 210, the orthographic projection of the light transmission hole 220 on the substrate 120 lies within the orthographic projection of the pixel limiting portion 310 on the substrate 120. That is, no through-holes are provided in the pixel limiting portion 310 corresponding to the light transmission hole 220, and the installation method of the pixel limiting portion 310 can be simplified.

[0114] Preferably, the pixel limiting portion 310 and the second sealing layer 600 are connected by contact within the light transmission hole 220. This improves the problem of the sealing layer being easily peeled off.

[0115] Preferably, the display panel further comprises a planarizing layer and a buffer layer sequentially provided on the side facing the substrate 120 of the defining layer, wherein the orthographic projection of the light-transmitting pore 220 on the substrate 120 lies within the orthographic projection of at least one of the buffer layer and the planarizing layer on the substrate 120. No holes are made in the buffer layer and planarizing layer in the region where the light-transmitting pore 220 is located, thereby allowing the buffer layer and planarizing layer to provide better support to the film layer, such as the isolation structure 200.

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

[0117] In some preferred embodiments, the minimum distance between the light-transmitting holes 220 and the isolation apertures 210 is 3 μm to 4 μm. That is, the minimum distance between the orthographic edge of the light-transmitting holes 220 on the array substrate 100 and the orthographic edge of the isolation apertures 210 on the array substrate 100 is 3 μm to 4 μm. This improves the situation where the distance between the light-transmitting holes 220 and the isolation apertures 210 is too large, affecting the distribution area of ​​the light-transmitting holes 220 and thus affecting the light transmittance of the display panel. It also improves the situation where the distance between the light-transmitting holes 220 and the isolation apertures 210 is too small, increasing process difficulty and causing mutual influence between the light-transmitting holes 220 and the isolation apertures 210.

[0118] Preferably, the minimum distance 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 distance 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 distance 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.

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

[0120] As shown in Figures 1 to 9, the first aspect of the present invention further provides a display panel comprising an array substrate 11 and an isolation structure 200, wherein the array substrate 11 comprises a substrate 120 and a metal structure 110 provided on the substrate 120, and the isolation structure 200 is provided on one side of the array substrate 11 and encloses and closes to form an isolation opening 210 and a light transmission hole 220, and the orthographic projection of the light transmission hole 220 on the substrate 120 and the orthographic projection of the metal structure 110 on the substrate 120 are The isolation opening 210 is provided with at least a partial offset, and is used to accommodate at least some of the light-emitting units 400, of which the light-transmitting holes 220 comprises a first light-transmitting hole 221 and a second light-transmitting hole 222, the first light-transmitting hole 221 and the second light-transmitting hole 222 are located on the circumferential side of the same isolation opening 210, and the orthographic shape of the first light-transmitting hole 221 on the substrate 120 is different from the orthographic shape of the second light-transmitting hole 222 on the substrate 120.

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

[0122] The display panel of the embodiment of this application and the display panel of any one of the embodiments described above are mutually referential, and the same structure in the display panel of the embodiment of this application and the display panel of any one of the embodiments described above will not be described repeatedly here. For example, the display panel of the embodiment of this application may have structures such as the recessed portion 220d and the protruding portion 210a described above.

[0123] As shown in Figures 1 to 9, the first aspect of the present invention further provides a display panel comprising an array substrate 11, an isolation structure 200, and a light-emitting unit 400. The array substrate 11 comprises a substrate 120 and a first active layer 130 provided on the substrate 120. The isolation structure 200 is provided on one side of the array substrate 11 and encloses and closes to form a plurality of isolation openings 210 and a plurality of light-transmitting holes 220. 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 offset. The light-emitting unit 400 is provided corresponding to the isolation openings 210. The display panel 1 according to the present invention 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 and realize the display function of the display panel 1. The isolation structure 200 encloses and closes to form isolation openings 210 and light-transmitting holes 220. The isolation aperture 210 is used to expose the light-emitting unit 400 and enable light emission. The light-transmitting holes 220 are used to enable light transmission of the display panel 1 and increase the light transmittance of the display panel 1. 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 offset at least partially, thereby improving the influence of natural light rays in the light-transmitting holes 220 on the first active layer 130, enhancing the performance of the first active layer 130, and improving the usability of the display panel.

[0124] Preferably, as shown in Figures 3 and 8, the first active layer 130 includes a first channel area 131, and the orthographic projection of the light-transmitting holes 220 on the substrate 120 and the orthographic projection of the first channel area 131 on the substrate 120 are offset. That is, the first channel area 131 and the light-transmitting holes 220 are offset from each other, thereby reducing, and eventually eliminating, the amount of light incident from the light-transmitting holes 220 to the first channel area 131, improving the influence of light carriers on the first channel area 131, enhancing the performance of the first channel area 131, and improving the usability of the display panel.

[0125] There are several ways of setting the material of the first active layer 130, preferably the material of the first active layer 130 includes a metal oxide semiconductor material, for example, an indium gallium zinc oxide semiconductor material. Preferably, referring to the preceding paragraph, when the drive circuit T comprises a metal oxide transistor and a low-temperature polysilicon transistor, at least a part of the first active layer 130 may be the semiconductor portion of the metal oxide transistor.

[0126] In some preferred embodiments, as shown in Figures 3 and 8, the display panel further comprises a second active layer 140, wherein the orthographic projection of the second active layer 140 on the substrate 120 is at least partially offset from the orthographic projection of the light-transmitting holes 220 on the substrate 120. This improves the influence of natural light rays in the light-transmitting holes 220 on the second active layer 140, enhances the performance of the second active layer 140, and improves the usability of the display panel.

[0127] Preferably, as shown in Figure 3, the second active layer 140 includes a second channel area 141, and the orthographic projection of the second channel area 141 on the substrate 120 and the orthographic projection of the light transmission holes 220 on the substrate 120 are offset at least partially. That is, the second channel area 141 and the light transmission holes 220 are offset from each other, thereby reducing, and eventually eliminating, the amount of light incident from the light transmission holes 220 into the second channel area 141, improving the influence of light carriers on the second channel area 141, enhancing the performance of the second channel area 141, and improving the usability of the display panel.

[0128] Alternatively, as shown in Figure 8, a light-shielding layer 150 is provided between the second channel area 141 and the isolation structure 200, and the orthographic projection of the second channel area 141 on the substrate lies within the orthographic projection of the light-shielding layer 150 on the substrate. The presence of the light-shielding layer 150 reduces, and eventually eliminates, the amount of light incident on the second channel area 141 from the light-transmitting holes 220, improving the influence of light carriers on the second channel area 141, enhancing the performance of the second channel area 141, and improving the usability of the display panel.

[0129] There are several possible installation positions for the light-shielding layer 150, and the light-shielding layer 150 may be provided in the same layer as the capacitor plates, gate electrodes, signal lines, etc. Preferably, the material of the light-shielding layer 150 may include a metallic light-shielding material, thereby providing the light-shielding layer 150 with good light-shielding performance.

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

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

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

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

[0134] As shown in Figures 10 to 16, the first aspect of the present invention 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 comprises a plurality of light-emitting units 400, with at least some isolation structures 200 surrounding and closing to form isolation openings 210 and light-transmitting holes 220, the isolation openings 210 being used to expose the light-emitting units 400, and the light-transmitting holes 220 being formed between at least some adjacent isolation openings 210, the isolation structures 200 comprising first equal-width segments 153 surrounding the light-transmitting holes 220, the orthogonal projection of at least the first equal-width segments 153 on the array substrate 11 being located between the orthogonal projection of the light-transmitting holes 220 on the array substrate 11 and the orthogonal projection of the isolation openings 210 on the array substrate 11, the first equal-width segments 153 being provided with equal widths and having a width direction from one of the orthogonal projections of the light-transmitting holes 220 on the array substrate 11 to the other.

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

[0136] The display panel 1 according to the present invention comprises an array substrate 11, a light-emitting layer 40, and an isolation structure 200. The light-emitting layer 40 comprises a plurality of light-emitting units 400 used to emit light and realize the display function of the display panel 1. The isolation structure 200 encloses and closes to form isolation openings 210 and light-transmitting holes 220. The isolation openings 210 are used to expose the light-emitting units 400 and enable light emission. The light-transmitting holes 220 are located between at least some adjacent isolation openings 210, that is, the orthographic projections on the array substrate 11 are located between the orthographic projections of at least some of the light-emitting units 400 on the array substrate 11, thereby enabling light transmission in the region between adjacent light-emitting units 400 and increasing the light transmittance of the display panel 1. The isolation structure 200 comprises a first equal-width segment 153 surrounding the light-transmitting hole 220. The first equal-width segment 153 is located between the light-transmitting hole 220 and the isolation opening 210 and is provided at equal widths. That is, a portion of the isolation structure 200 between the light-transmitting hole 220 and the isolation opening 210 is provided at equal widths, ensuring that the area of ​​the isolation opening 210 is constant. On the premise of ensuring manufacturing yield, the area of ​​the light-transmitting hole 220 can be maximized, increasing the distribution area of ​​the light-transmitting hole 220 and increasing the light transmittance of the display panel 1.

[0137] Preferably, the opening shape of the light-transmitting hole 220 is rationally set, for example, so that the shape of the light-transmitting hole 220 matches the shape of the isolation opening 210, and the light-transmitting hole 220 has an irregular shape, thereby enabling the first equal-width segments 153 to be provided at equal widths, and maximizing the area of ​​the light-transmitting hole 220 can be achieved.

[0138] Furthermore, the display effect of the display panel 1 can be enhanced by providing the first equal-width segments 153 with equal widths such that the amount of reflection at different positions of the first equal-width segments 153 for light rays is approximately the same. The width direction of the first equal-width segment 153 is the direction from one of the orthographic projections of the light-transmitting holes 220 and the isolation apertures 210 on the array substrate 11 located on both sides of it to the other. For example, the width direction of the first equal-width segment 153 may be the direction from the geometric center of the orthographic projection on one array substrate 11 to the geometric center of the orthographic projection on the other array substrate 11, among the orthographic projections of the light-transmitting holes 220 and the isolation apertures 210 on the array substrate 11 located on both sides of it.

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

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

[0141] In these preferred embodiments, the isolation structure 200 comprises a first sublayer 201 and a second sublayer 202, wherein the second sublayer 202 is located on the side of the first sublayer 201 away from the array substrate 11, and the orthographic projection of the first sublayer 201 on the array substrate 11 lies within the orthographic projection of the second sublayer 202 on the array substrate 11, i.e., the orthographic area of ​​the first sublayer 201 is smaller than the orthographic area of ​​the second sublayer 202, thereby allowing an indentation to be formed beneath the second sublayer 202. When subsequently manufacturing the light-emitting unit 400, the light-emitting material can be divided at the edge of the second sublayer 202 to form independent light-emitting units 400, thereby eliminating the manufacturing process of the precision mask and simplifying the manufacturing process of the display panel 1.

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

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

[0144] Preferably, the first equal-width segment 153 further comprises a first sub-segment 201a provided in the first sub-layer 201. That is, an equal-width segment is also provided within the first sub-layer 201, thereby ensuring a better match between the shape of the first sub-layer 201 and the shape of the second sub-layer 202, and guaranteeing the performance of the isolation structure 200.

[0145] In one viable embodiment, the width D of the first equal-width segment 153 is 1 μm to 4 μm along a direction parallel to the plane on which the array substrate 11 is located. For example, the width D of the first equal-width segment 153 may be 1 μm, 1.1 μm, 1.5 μm, 1.8 μm, 2 μm, 2.3 μm, 2.7 μm, 2.9 μm, 3 μm, 3.2 μm, 4 μm, etc., i.e., the orthographic width D of the first equal-width segment 153 on the array substrate 11 is 1 μm to 4 μm. This can improve the situation where the width of the first equal-width segment 153 is too small, making process manufacturing too difficult and affecting the manufacturing of the display panel 1, and it can also improve the situation where the width of the first equal-width segment 153 is too large, affecting the distribution area of ​​the light-transmitting holes 220 and affecting the light transmittance of the display panel 1.

[0146] Preferably, when the isolation structure 200 comprises a first sublayer 201 and a second sublayer 202, the width of the first subsegment 201a along the direction parallel to the plane on which the array substrate 11 is located is a first preset dimension D1, and the first preset dimension D1 is 1 μm to 3 μm. For example, the first preset dimension D1 may be 1 μm, 1.1 μm, 1.5 μm, 1.8 μm, 2 μm, 2.3 μm, 2.7 μm, 2.9 μm, 3 μm, etc.

[0147] Preferably, the width of the second subsegment 202a along the direction parallel to the plane on which the array substrate 11 is located is a second preset dimension D2, and the second preset dimension D2 is 2 μm to 4 μm. For example, the second preset dimension D2 may be 2 μm, 2.3 μm, 2.7 μm, 2.9 μm, 3 μm, 3.2 μm, 4 μm, etc.

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

[0149] There are several installation methods for the light-emitting unit 400. For example, the light-emitting unit 400 comprises a first electrode 410, a light-emitting functional layer 420, and a second electrode 430, which are stacked along a direction away from the array substrate 11. The material of the isolation structure 200 may include a conductive material, thereby enabling the second electrode 430 to be electrically connected to the isolation structure 200, and the isolation structure 200 enables the arrangement of the second electrodes 430 of multiple light-emitting units 400 across their entire surfaces.

[0150] For example, preferably, 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 multiple light-emitting units 400 can be connected to each other by the first sublayer 201 to form a surface electrode.

[0151] Preferably, the material of the second sublayer 202 includes a conductive material, and the second sublayer 202 is electrically connected to the second electrode 430. This increases the distribution area of ​​the conductive material and reduces the voltage drop of the second electrode 430 at different locations within the display area AA.

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

[0153] In these preferred embodiments, the isolation structure 200 further comprises a second equiwidth segment 154 located between two adjacent isolation openings 210, the second equiwidth segment 154 being of equal width, thereby substantially matching the light ray reflectivity at different positions in the second equiwidth segment 154 and improving the display effect of the display panel 1.

[0154] The width direction of the second equal-width segment 154 is the direction from one of the orthographic projections of the two isolated apertures 210 located on either side of the array substrate 11 to the other. For example, the width direction of the second equal-width segment 154 is the direction from the geometric center of the orthographic projection on one array substrate 11 to the geometric center of the orthographic projection on the other array substrate 11 of the two isolated apertures 210 located on either side of the array substrate 11.

[0155] There are several 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.

[0156] In these preferred 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, ensuring that the light-transmitting holes 220 have a sufficient opening area and thus guaranteeing the light transmittance of the display panel 1.

[0157] Furthermore, in order to ensure that the light-transmitting holes 220 have a sufficiently large opening area, the width of the first equal-width segment 153 is usually set to the minimum width within the process's tolerance range. If the minimum width d1 of the first equal-width segment 153 and the minimum width d2 of the second equal-width segment 154 satisfy d2 ≤ 2d1, the second equal-width segment 154 is not suitable for forming the light-transmitting holes 220 in order to avoid adverse effects on the function of the isolation structure 200 due to limitations in the manufacturing process.

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

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

[0160] Alternatively, the first sub-area and the second sub-area are provided integrally, and the sum of the minimum widths of the orthographic projection of the first sub-area on the array substrate 11 and the minimum width of 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. This ensures that the integrally provided first sub-area and second sub-area have a sufficiently small width, thereby reducing the influence of this on the light transmittance of the display panel 1.

[0161] In one viable embodiment, the minimum orthographic width of the connection portion 1310 on the array substrate 11 is the third preset dimension D3, and the third preset dimension D3 and the minimum orthographic width d1 of the first equal-width segment 153 on the array substrate 11 satisfy D3 = d1. As a result, the connection portion 1310 has a sufficiently small width, the distribution area of ​​the isolation structure 200 is further reduced, the distribution area of ​​the light transmission holes 220 is increased, and the light transmittance of the display panel 1 is increased.

[0162] In one viable embodiment, the light-emitting unit 400 comprises a first light-emitting unit 401, a second light-emitting unit 402, and a third light-emitting unit 403, each having a different color.

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

[0164] In one viable embodiment, as shown in Figures 13 and 14, the isolation opening 210 comprises a first isolation opening 211 used to expose a first light-emitting unit 401, a second isolation opening 212 used to expose a second light-emitting unit 402, and a third isolation opening 213 used to expose a third light-emitting unit 403. The first isolation opening 211 and the second isolation opening 212 are arranged alternately along a second direction Y intersecting a first direction X to form a first opening row A1, and the plurality of third isolation openings 213 are arranged along the second direction Y to form a second opening row A2, and the first opening row A1 and the second opening row A2 are arranged alternately along the first direction X.

[0165] In the above embodiment, the third light-emitting unit 403 is provided surrounding the first light-emitting unit 401, the third light-emitting unit 403 is provided surrounding the second light-emitting unit 402, and the first light-emitting unit 401 and the second light-emitting unit 402 are provided alternately surrounding the third light-emitting unit 403. This makes it possible to achieve a good light mixing effect and improve the light output quality of the display panel 1.

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

[0167] In the above embodiment, the distance between the first isolation opening 211 and the third isolation opening 213 is small and unsuitable for installing the light-transmitting hole 220; therefore, a second equal-width segment 154 may 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 and unsuitable for installing the light-transmitting hole 220; therefore, a second equal-width segment 154 may be provided between the second isolation opening 212 and the third isolation opening 213.

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

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

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

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

[0172] The above installation method for the third isolation opening 213 makes it possible to achieve relatively strong uniformity in the distribution of the third isolation opening 213 along the circumferential direction of the first isolation opening 211, thereby improving the uniformity of the display panel 1.

[0173] At the same time, the above installation method for the third isolation opening 213 makes it possible to relatively improve the uniformity of the distribution of the third isolation opening 213 along the circumferential direction of the second isolation opening 212, thereby further improving the uniformity of the display panel 1.

[0174] In one viable embodiment, as shown in Figure 13, the first isolation opening 211 is located at two opposing vertices of the virtual quadrilateral M1, the second isolation opening 212 is located at the other two opposing vertices of the virtual quadrilateral M1, and 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 holes 220 on the array substrate 11.

[0175] In the above embodiment, the distance between adjacent first isolation openings 211 and second isolation openings 212 on the shortest side of the virtual quadrilateral M1 is small, making it unsuitable for installing light-transmitting holes 220 in order to ensure the yield of the isolation structure 200.

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

[0177] In other embodiments, as shown in Figures 15 and 16, the isolation structure 200 may be an auxiliary cathode. For example, the second electrode 430 is a surface electrode, the isolation structure 200 is located on the side of the second electrode 430 away from the array substrate 11, and an insulating layer 16 may be provided between the isolation structure 200 and the second electrode 430, and the isolation structure 200 and the second electrode 430 are via-connected.

[0178] The present invention further provides another display panel 1, as shown in Figures 10 to 14, comprising an array substrate 11, a light-emitting layer 40 located on one side of the array substrate 11 and comprising a plurality of light-emitting units 400, and an isolation structure 200 that at least partially encloses and closes isolation openings 210 for exposing the light-emitting units 400, and at least some of the isolation structure 200 that forms light-transmitting holes 220 formed between adjacent isolation openings 210, wherein the isolation structure 200 comprises a second equal-width segment 154 surrounding the isolation openings 210, the orthographic projection of at least 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 segment 154 is provided with equal width, and its width direction is from one of the orthographic projections of two adjacent isolation openings 210 on the array substrate 11 to the other.

[0179] The display panel 1 according to the present invention comprises an array substrate 11, a light-emitting layer 40, and an isolation structure 20015. The light-emitting layer 40 comprises a plurality of light-emitting units 400 used to emit light and realize the display function of the display panel 1. The isolation structure 200 further comprises a second equal-width segment 154 located between two adjacent isolation openings 210, and the second equal-width segment 154 is provided with equal widths, thereby making the light ray reflection capability at different positions in the second equal-width segment 154 substantially the same, and improving the display effect of the display panel 1.

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

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

[0182] Furthermore, in order to ensure that the light-transmitting holes 220 have a sufficiently large opening area, the width of the first equal-width segment 153 is usually set to the minimum width within the process's tolerance range. If the minimum width d1 of the first equal-width segment 153 and the minimum width d2 of the second equal-width segment 154 satisfy d2 ≤ 2d1, the second equal-width segment 154 is not suitable for forming the light-transmitting holes 220 in order to avoid adverse effects on the function of the isolation structure 200 due to limitations in the manufacturing process.

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

[0184] Alternatively, the first sub-area and the second sub-area are provided integrally, and the sum of the minimum widths of the orthographic projection of the first sub-area on the array substrate 11 and the minimum width of the orthographic projection of the second sub-area on the array substrate 11 is less than or equal to 2d1. This ensures that the first sub-area and the second sub-area, which are provided integrally, have a sufficiently small width, thereby reducing their influence on the light transmittance of the display panel 1.

[0185] In some preferred embodiments, the second equal-width segment 154 comprises a first sub-area and a second sub-area spaced apart, the first sub-area and the second sub-area spaced apart and connected by a connecting portion 1310, such that the minimum orthographic width d3 of the connecting portion 1310 on the array substrate 11 and the minimum orthographic width d1 of the first equal-width segment 153 on the array substrate 11 satisfy d3=d1. As a result, the connecting portion 1310 has a sufficiently small width, further reducing the distribution area of ​​the isolation structure 200, increasing the distribution area of ​​the light-transmitting holes 220, and increasing the light transmittance of the display panel 1.

[0186] In this embodiment, the installation method of the light-emitting unit 400 and the isolation structure 200 is as described above and will not be explained again here. The display panel 1 of this embodiment and the display panel 1 of any one of the above embodiments are mutually referential.

[0187] The present invention further provides another display panel 1 having a first display area and a second display area provided around at least a portion of the first display area, as shown in Figures 10 to 14, wherein the display panel 1 comprises an array substrate 11, a light-emitting layer 40 located on one side of the array substrate 11 and comprising a plurality of light-emitting units 400, and isolation openings 210 that at least a portion enclose and are located in the first display area and used to expose the light-emitting units 400, and isolation openings that form light-transmitting holes 220 formed between at least a portion of adjacent isolation openings 210. The structure 200 comprises, of which the isolation structure 200 includes a first equal-width segment 153 surrounding the light-transmitting hole 220, wherein the orthographic projection of at least the first equal-width segment 153 on the array substrate 11 is located between the orthographic projection of adjacent isolation apertures 210 on the array substrate 11 and the orthographic projection of the light-transmitting hole 220 on the array substrate 11, and the first equal-width segment 153 is provided with equal width, and its width direction is from one of the orthographic projections of the light-transmitting hole 220 on the array substrate 11 to the other.

[0188] In the embodiment of the present invention, by providing the light-transmitting holes 220 in the first display area, the light transmittance of the first display area can be increased, enabling under-display integration of the light detection module in the first display area. A first equal-width segment 153 is provided within the first display area, and the first equal-width segment 153 is provided with equal widths, that is, a portion of the isolation structure 200 between the light-transmitting holes 220 and the isolation opening 210 is provided with equal widths, thereby ensuring that the area of ​​the isolation opening 210 is constant and, on the premise of ensuring manufacturing yield, the area of ​​the light-transmitting holes 220 can be maximized to increase the distribution area of ​​the light-transmitting holes 220 and increase the light transmittance of the display panel 1.

[0189] In this embodiment, the installation method of the light-emitting unit 400 and the isolation structure 200 is as described above and will not be explained again here. The display panel 1 of this embodiment and the display panel 1 of any one of the above embodiments are mutually referential.

[0190] The present invention further provides a display device 2 comprising one of the display panels 1 according to the above embodiment of the present invention, as shown in Figure 17.

[0191] The display device 2 according to the present invention is further equipped with a light detection module, which is integrated within the display panel 1 or located on the side away from the light-emitting layer 40 of the array substrate 11, thereby increasing the light transmittance of the display panel 1, enabling the light detection module to receive light rays more effectively, and improving the yield of the light detection module's work.

[0192] In embodiments of the present invention, the display panel comprises an array substrate 100 and an isolation structure 200 that encloses and closes to form isolation openings 210 and light-transmitting holes 220. The isolation openings 210 are used to house light-emitting units 400, thereby improving mutual crosstalk between adjacent light-emitting units 400 and enabling light-emitting display of the display panel. The array substrate 100 comprises a substrate 120 and a metal structure 110 provided on the substrate 120, the metal structure 110 being usable to drive the light emission of the light-emitting units 400. The light-transmitting holes 220 are used to increase the light transmittance of the display panel and facilitate under-display integration of light-sensing modules. 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 provided at least partially offset, thereby improving the influence of the metal structure 110 on the light transmittance of the light-transmitting holes 220. Typically, the distribution shape of the metal structure 110 corresponding to the periphery of the same isolation aperture 210 on the substrate differs, and the orthographic projection shapes of the first light-transmitting hole 221 and the second light-transmitting hole 222 on the substrate differ. This makes it easier for the user to rationally set the shapes of the first light-transmitting hole 221 and the second light-transmitting hole 222 based on the distribution of the metal structure 110 within the substrate so that their dimensions better match the distribution shape of the metal structure 110 within the substrate. This maximizes the distribution area of ​​the light-transmitting holes 220, improves signal interference problems caused by exposure of the metal structure 110 from the light-transmitting holes 220, and enhances the usability of the display panel.

[0193] The display panel of the embodiment of the present application and the display panel of any one of the above embodiments are mutually referable. 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 dimensions of the first light-transmitting holes 221 and the second light-transmitting holes 222 are better suited to the distribution shape of the metal structure 110 in the substrate.

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

[0195] Preferably, the light-transmitting hole 220 has the first side 230 described above, and the isolation opening 210 has the second side 240 described above. The installation method of the first side 230 and the second side 240 is as described in the preceding paragraph and will not be repeated here. The light-transmitting hole 220 may further include the first right side 220a described above. As shown in Figures 1 to 17, the second side embodiment of the present application further provides a display device comprising the display panel 10 of any one of the first side embodiment described above. Since the display device according to the second side embodiment of the present application comprises the display panel 10 of any one of the first side embodiment described above, it has the beneficial effects of the display panel 10 of any one of the first side embodiment described above and will not be repeated here.

[0196] The display devices in the embodiments of this application include, but are not limited to, devices having display functions such as mobile phones, personal digital assistants (PDAs), tablets, e-readers, televisions, access control systems, smart landline phones, and consoles.

[0197] While the present application has been described with reference to preferred embodiments, various improvements can be made thereto without departing from the scope of the application, and some of its components can be replaced with equivalents. In particular, the technical features of each section mentioned in each embodiment can be combined in any way, provided that no structural conflicts exist.
