Preferably, two first directions Y, two second directions Z, and two thickness directions X may be perpendicular to each other.

[0017] As shown in FIGS. 1 to 3 , an embodiment of a first aspect of the present application provides a display panel 10. The display panel 10 according to the embodiment of the first aspect of the present application includes a substrate 100, an isolation structure 300, and a light-emitting functional layer 40. The isolation structure 300 is provided on one side of the substrate 100 and includes the isolation structure 300 and a first limiting opening 310 formed by the isolation structure 300 surrounding and closing the first limiting opening 310. The isolation structure 300 includes an isolation portion 300a located between two adjacent limiting openings, and the isolation portion 300a includes a light-shielding portion 300b. The light-emitting functional layer 40 includes a first electrode 410, a light-emitting unit 420 and a light-emitting layer 420, at least a portion of which is located within the first limiting opening 310 and which are sequentially stacked in a direction away from the substrate 100. and a second electrode 430, and at least a portion of each of the first electrode 410, the light-emitting unit 420 and the second electrode 430 is used to form a sub-pixel 400, of which at least one first limiting aperture 310 has a first aperture region 311 and a second aperture region 312, the orthogonal projection of the first electrode 410 on the substrate 100 coincides with the orthogonal projection of the first aperture region 311 on the substrate 100, a light-transmitting gap TG is formed between the orthogonal projection of the first electrode 410 on the substrate 100 and the orthogonal projection of the edge of the light-shielding portion 300b of the corresponding isolation portion 300a on the substrate 100, and the orthogonal projection of the second region on the substrate 100 is located within the orthogonal projection of the light-transmitting gap TG on the substrate 100.

[0018] The display panel 10 according to the embodiment of the present application includes a substrate 100, an isolation structure 300, and a light-emitting functional layer 40. The isolation structure 300 is disposed on one side of the substrate 100 and includes an isolation structure 300, which surrounds and closes the isolation structure 300 to form a first limiting opening 310. The first limiting opening 310 is used to accommodate the sub-pixels 400 and to alleviate the problem of mutual interference of light emitted from different sub-pixels 400. The light-emitting functional layer 40 includes a first electrode 410, a light-emitting unit 420, and a second electrode 430, and the first electrode 410 and the second electrode 430 are used to drive the light-emitting unit 420 to emit light and realize light emission from the sub-pixels 400. At least one first limiting aperture 310 includes a first aperture region 311 and a second aperture region 312 that are connected to each other. The orthogonal projection of the first electrode 410 on the substrate 100 coincides with the orthogonal projection of the first aperture region 311 on the substrate 100, and the first aperture region 311 is used to realize light emission of the display panel 10. A light-transmitting gap TG located within the first limiting aperture 310 is formed between the orthogonal projection of the first electrode 410 on the substrate 100 and the orthogonal projection of the edge of the light-shielding portion 300b of the corresponding isolation portion 300a on the substrate 100. The orthogonal projection of the second aperture region 312 on the substrate 100 coincides with the orthogonal projection of the light-transmitting gap TG on the substrate 100, that is, the second aperture region 312 is used to realize light transmission of the display panel 10.

[0019] In the practice of the present application, the first opening region 311 for realizing light emission and the second opening region 312 for realizing light transmission are connected to each other, so that light can be effectively transmitted through the display panel 10 in the thickness direction X of the display panel 10 through the second opening region 312, thereby effectively improving the light transmittance of the display panel 10. The communication between the second opening region 312 and the first opening region 311 can reduce the proportion of the distribution area of ​​the light-shielding portion 300b between adjacent sub-pixels 400 to about half compared to an embodiment in which the light-transmitting opening and the isolating opening are provided at an interval, thereby effectively increasing the distribution area of ​​the light-transmitting region and improving the light transmittance and aperture ratio of the display panel.

[0020] The first opening area 311 in the present application may be an isolation opening in a preferred embodiment, and the second opening area 312 in the present application is a light-transmitting groove in a preferred embodiment.

[0021] The sub-pixel 400 in this application refers to an area capable of emitting light in the light-emitting functional layer 40. For example, the display panel 10 further includes a pixel defining layer, which includes a pixel limiting portion 200 and a pixel opening 210 formed by the pixel limiting portion 200 surrounding the pixel opening 210, the first electrode 410 being exposed from the pixel opening 210, at least a portion of the light-emitting unit 420 being located within the pixel opening 210, and the second electrode 430 being located on the side of the light-emitting unit 420 facing away from the substrate 100, and the first electrode 410, the light-emitting unit 420, and the second electrode 430 corresponding to the area where the pixel opening 210 is located constitute a sub-pixel 400.

[0022] Preferably, the first limiting aperture 310 may be provided corresponding to one or more pixel apertures 210, for example, the orthogonal projection of one pixel aperture 210 on the substrate 100 is located within the orthogonal projection of one first limiting aperture 310 on the substrate 100, or the orthogonal projection of two or more pixel apertures 210 on the substrate 100 is located within the orthogonal projection of the same first limiting aperture 310 on the substrate 100.

[0023] The isolation structure 300 layer includes isolation structures 300 and first limiting apertures 310. Preferably, the isolation structures 300 have a lattice shape, and the isolation portions 300a are portions of the isolation structures 300 located between two adjacent first limiting apertures 310. The light-shielding portions 300b are sublayers within the isolation portions 300a that do not transmit light. A light-transmitting gap TG is located between the edge of the first electrode 410 as orthogonally projected on the substrate 100 and the edge of the isolation portions 300a facing the first limiting apertures 310 for accommodating the first electrode 410 as orthogonally projected on the substrate 100. That is, the distribution area of ​​the first limiting apertures 310 is larger than the distribution area of ​​the corresponding first electrodes 410 located therein. As a result, a light-transmitting gap TG is formed between the first electrode 410 and the edge of the isolation portions 300a facing the first limiting apertures 310. The second aperture regions 312 are located within the light-transmitting gap TG.

[0024] In still other preferred embodiments, the orthogonal projection of the pixel opening 210 on the substrate 100 is located within the orthogonal projection of the first limiting opening 310 on the substrate 100.

[0025] In some embodiments of the present application, the first opening region 311 and the second opening region 312 are connected, and the second opening region 312 may be recessed on the surface of the isolation structure 300 facing the first opening region 311, i.e., recessed relative to the wall surface of the isolation structure 300 that surrounds and defines the first opening region 311. Preferably, the recessed shape of the second opening region 312 may be formed in a variety of ways. For example, the orthographic shape of the second opening region 312 on the substrate 100 may be polygonal, or may be an arc shape such as a semicircle or semiellipse, and the present application is not specifically limited thereto. Among these, the orthogonal projection of the second opening region 312 on the substrate 100 may mean the projection region formed by the orthogonal projection of the surface of the inner wall of the second opening region 312 on the substrate 100, or, as described above, may mean the region where the orthogonal projection of the cutout portion on the substrate 100 is located, or may mean the region within the limited opening that is misaligned with the orthogonal projection of the pixel opening 210 on the substrate 100.

[0026] Preferably, the number of first limiting apertures 310 and sub-pixels 400 may be plural, and each first limiting aperture 310 may correspond to one sub-pixel 400. The isolation structure 300 may have a mesh-like shape, and the hollowed-out areas of the mesh-like isolation structure 300 may form the first limiting apertures 310.

By providing the second through-hole 421 in the light-emitting unit 420 and arranging the second through-hole 421 corresponding to the light-transmitting gap TG, the light transmittance of the light-transmitting gap TG can be further enhanced, thereby enhancing the light transmittance of the display panel 10.

[0031] Preferably, the orthogonal projection of the second lightening opening 421 on the substrate 100 at least partially overlaps with the orthogonal projection of the second opening region 312 on the substrate 100, thereby further increasing the light transmittance of the second opening region 312.

[0032] 4 and 5, the second electrode 430 includes a light-transmitting material layer to enhance the light transmittance of the display panel 10. Alternatively, as shown in FIGS. 4, 6, and 7, the second electrode 430 has a third lightening opening 431 formed therethrough, and the orthogonal projection of the third lightening opening 431 on the substrate 100 at least partially overlaps with the orthogonal projection of the light-transmitting gap TG on the substrate 100. By forming the third lightening opening 431 in the second electrode 430 and arranging the third lightening opening 431 corresponding to the light-transmitting gap TG, the light transmittance of the light-transmitting gap TG can be further enhanced, thereby enhancing the light transmittance of the display panel 10.

[0041] Preferably, the first sealing portion 511 extends from the first limiting opening 310 to a side of the isolation structure 300 that is away from the substrate 100, thereby increasing the distribution area of ​​the first sealing portion 511 and improving the sealing effect of the first sealing portion 511.

[0049] In some preferred embodiments, as shown in FIG. 10, the display panel 10 has a first display area AA1 and a second display area AA2, the light transmittance of the first display area AA1 is greater than that of the second display area AA2, the driving circuit 150 is located in the second display area AA2, the first electrode 410 connected to the connection portion 411 is located in the first display area AA1, the material of the connection portion 411 includes a light-transmitting material, and the connection portion 411 extends from the first display area AA1 to the second display area AA2.

[0050] In these preferred embodiments, the light transmittance of the first display area AA1 is greater than that of the second display area AA2, and the first display area AA1 can be used to realize under-display integration of a light-sensing module. The connection portion 411 extends from the first display area AA1 to the second display area AA2, so that the driving circuit 150 for driving the components in the first display area AA1 is provided in the second display area AA2, thereby further increasing the light transmittance of the display panel 10.

[0051] Preferably, the isolation structure 300 encloses and forms a third limiting aperture 340 located in the second display area AA2, and the third limiting aperture 340 may not include the second opening area 312.

[0052] As described above, the display panel 10 further includes a pixel defining layer, which further includes a pixel defining portion 200 and a pixel opening 210 surrounded and closed by the pixel defining portion 200. The isolation structure 300 is disposed on the side of the pixel defining portion 200 facing away from the substrate 100. The pixel opening 210 communicates with the first limiting opening 310. At least some of the light-emitting units 420 are located in the pixel opening 210. As shown in FIGS. 1 to 9 , the pixel defining portion 200 may be made of a light-transmitting material. Alternatively, as shown in FIG. 11 , the pixel defining portion 200 may have a limiting layer opening 230 formed therein. The orthogonal projection of the limiting layer opening 230 on the substrate 100 at least partially overlaps with the orthogonal projection of the second opening region 312 on the substrate 100. That is, the pixel defining portion 200 may have a limiting layer opening 230 corresponding to the second opening region 312, thereby further enhancing the light transmittance at the location of the second opening region 312. 11, the limiting layer opening 230 and the pixel opening 210 are in communication with each other. In other embodiments, the limiting layer opening 230 and the pixel opening 210 may be spaced apart from each other, i.e., a portion of the pixel limiting portion 200 exists between the limiting layer opening 230 and the pixel opening 210.

[0053] In these preferred embodiments, the pixel opening 210 and the first limiting opening 310 are connected to each other, so that light emitted from the light-emitting unit 420 in the pixel opening 210 can be emitted through the first limiting opening 310. The material of the pixel limiting portion 200 may include a light-transmitting material to improve the light transmittance of the display panel 10. If the material of the pixel defining layer is not a light-transmitting material, the pixel limiting portion 200 may have a limiting layer opening 230 corresponding to the second opening region 312 to further improve the light transmittance at the location of the second opening region 312.

[0054] 12 , the display panel 10 may further include a filter layer 700, which is located on the side of the light-emitting functional layer 40 that is farther from the substrate 100. If the display panel 10 includes the encapsulation layer 500, the filter layer 700 may be located on the side of the encapsulation layer 500 that is farther from the substrate 100, so as to improve the influence on the light-emitting functional layer 40 and enhance the encapsulation effect of the encapsulation layer 500.

[0055] Preferably, the filter layer 700 comprises a light-shielding limiting portion 710, a second limiting opening 720 formed by the light-shielding limiting portion 710 surrounding and closing it, and a filter unit 730 at least a portion of which is located in the second limiting opening 720, wherein the second limiting opening 720 comprises a third opening region 721 and a fourth opening region 722, the orthogonal projection of the fourth opening region 722 on the substrate 100 at least partially overlaps with the orthogonal projection of the second opening region 312 on the substrate 100, and the filter unit 730 is located in the third opening region 721.

[0056] In these preferred embodiments, the light-shielding limiting portion 710 surrounds and closes the second limiting opening 720, and the second limiting opening 720 is provided with two areas, a third opening area 721 and a fourth opening area 722. The third opening area 721 is provided corresponding to the first opening area 311 and is used to accommodate the filter unit 730 and filter the light emitted from the light-emitting unit. The fourth opening area 722 is provided corresponding to at least a portion of the second opening area 312, i.e., the light-shielding limiting portion 710 is not provided on at least a portion of the second opening area 312, which can further improve the light transmittance of the second opening area 312.

[0057] Preferably, the orthogonal projection of at least a portion of the filter units 730 on the substrate 100 is located outside the orthogonal projection of the fourth opening region 722 on the substrate 100. This improves the effect of the filter units 730 on the light transmittance at the location of the fourth opening region 722.

[0058] Preferably, the filter unit 730 covers at least a portion of the light-shielding limiting portion 710. By covering the surface of the light-shielding limiting portion 710 that faces away from the substrate 100, the filter unit 730 can reduce the reflectance of the surface of the light-shielding limiting portion 710 that faces away from the substrate 100, thereby improving the display effect of the display panel 10.

[0059] In some preferred embodiments, as shown in Figures 2 and 3, the substrate 100 is provided with a driving circuit layer, which has a light-transmitting structure, and the orthogonal projection of the light-transmitting structure on the substrate 100 at least partially overlaps with the orthogonal projection of the second opening area 312 on the substrate 100.

[0060] In these preferred embodiments, a light-transmitting structure is provided in the driving circuit layer, and the light-transmitting structure is provided corresponding to the second opening region 312, so that the light transmittance of the second opening region 312 can be improved.

[0061] Preferably, the driving circuit layer includes a conductive function section, and the orthogonal projection of the conductive function section on the substrate 100 is located outside the orthogonal projection of the second opening region 312 on the substrate 100. The material of the conductive function section usually includes a light-shielding metal material. By locating the orthogonal projection of the conductive function section on the substrate 100 outside the orthogonal projection of the second opening region 312 on the substrate 100, the influence of the conductive function section on the light transmittance of the second opening region 312 can be improved. Preferably, gaps are formed between the multiple conductive function sections, and the gaps form a light-transmitting structure. The conductive function section includes signal lines such as data signal lines, scanning signal lines, power signal lines, and light-emitting control signal lines. The conductive function section may further include elements such as semiconductor sections, first capacitor plates, and second capacitor plates. A gap is formed between the signal lines, between the signal lines and elements, or between the elements to form a light-transmitting structure and enhance the light transmittance of the display panel.

[0062] There are several ways to install the light-shielding portion 300b in the isolation portion 300a. For example, as shown in Figures 2 and 3, the isolation structure 300 includes a first isolation portion 301 and a second isolation portion 302 that are stacked in a direction away from the substrate 100, and the second isolation portion 302 protrudes from the first isolation portion 301 toward the first limiting opening 310. That is, the orthogonal projection of the first isolation portion 301 on the substrate 100 is located within the orthogonal projection of the second isolation portion 302 on the substrate 100.

[0063] In these preferred embodiments, the second isolation portions 302 protrude from the first isolation portions 301 toward the first limiting openings 310. This allows the second isolation portions 302 located on the periphery of the first limiting openings 310 to shield at least a portion of the material used to form the light-emitting units 420 and the second electrodes 430 of the display panel 10 during deposition of the light-emitting units 420 and the second electrodes 430, thereby effectively isolating the light-emitting units 420 and the second electrodes 430 between adjacent sub-pixels 400 and facilitating the formation of multiple spaced-apart sub-pixels 400. This eliminates the need for high-precision masks during deposition of the light-emitting units 420 and the second electrodes 430 of the display panel 10. For example, a fine metal mask (FMM) is not required during deposition of the light-emitting units 420 and the second electrodes 430, thereby significantly reducing the production costs of the display panel 10.

[0064] Preferably, the second isolation portions 302 on the peripheral side of the first limiting opening 310 may all be arranged to protrude from the first isolation portion 301, so that when the light-emitting unit 420 and the second electrode 430 of the display panel 10 are deposited, the materials of the light-emitting unit 420 and the second electrode 430 can be well blocked by the isolation structure 300 on the peripheral side of the first limiting opening 310.

[0065] Preferably, the light-shielding portion 300b includes a first isolation portion 301 and / or a second isolation portion 302. That is, the light-transmitting gap TG may be located between the orthogonal projection of the edge of the first isolation portion 301 and / or the second isolation portion 302 on the substrate 100 and the orthogonal projection of the first electrode 410 on the substrate 100.

[0066] Preferably, when the material of the second isolation portion 302 includes a light-transmitting material, the light-shielding portion 300b includes the first isolation portion 301, i.e., the light-transmitting gap TG is between the orthogonal projection of the edge of the first isolation portion 301 on the substrate 100 and the orthogonal projection of the first electrode 410 on the substrate 100.

[0067] In still other preferred embodiments, the isolation structure 300 may further include a third isolation portion 303, which protrudes from the first isolation portion 301 toward the first limiting opening 310, i.e., the orthogonal projection of the first isolation portion 301 on the substrate 100 is located within the orthogonal projection of the third isolation portion 303 on the substrate 100. In other words, the dimensions of the second isolation portion 302 and the third isolation portion 303 are both larger than the dimension of the first isolation portion 301.

[0068] The third isolation portion 303 protrudes from the first isolation portion 301 toward the first limiting opening 310, which allows the third isolation portion 303 to have a large extension dimension and a large area for connecting to the second electrode 430, thereby improving the reliability of the connection between the isolation structure 300 and the second electrode 430. The material of the third isolation portion 303 may include a conductive material.

[0069] Preferably, the light blocking portion 300b may include a second isolation portion 302 and / or a third isolation portion 303.

[0070] Preferably, when the material of the second isolation portion 302 is a light-transmitting material, the light-shielding portion 300b includes the third isolation portion 303, that is, the light-transmitting gap TG is between the orthogonal projection of the edge of the third isolation portion 303 on the substrate 100 and the orthogonal projection of the first electrode 410 on the substrate 100.

[0071] 13 to 16, the first limiting aperture 310 includes a first type limiting aperture 310a, a second type limiting aperture 310b, and a third type limiting aperture 310c, and the sub-pixels 400 include a first type sub-pixel 400a corresponding to the first type limiting aperture 310a, a second type sub-pixel 400b corresponding to the second type limiting aperture 310b, and a third type sub-pixel 400c corresponding to the third type limiting aperture 310c. The first type sub-pixels 400a, the second type sub-pixels 400b, and the third type sub-pixels 400c can be used to emit light of different colors, for example, the first type sub-pixels 400a are red sub-pixels, the second type sub-pixels 400b are green sub-pixels, and the third type sub-pixels 400c are blue sub-pixels. For example, the first type sub-pixel 400a is used to emit red light, the second type sub-pixel 400b is used to emit green light, and the third type sub-pixel 400c is used to emit blue light, wherein the materials of the light-emitting units 420 of the first type sub-pixel 400a, the second type sub-pixel 400b, and the third type sub-pixel 400c may be at least partially different so that the light-emitting colors of the first type sub-pixel 400a, the second type sub-pixel 400b, and the third type sub-pixel 400c are corresponding.

[0072] When the first limiting opening 310 includes the above-described first type limiting opening 310a, second type limiting opening 310b, and third type limiting opening 310c, at least one of the first type limiting opening 310a, second type limiting opening 310b, and third type limiting opening 310c has a first opening region 311 and a second opening region 312, and one or more second opening regions 312 are provided at intervals around the periphery of at least one first opening region 311. In other words, by enlarging at least one of the first type limiting opening 310a, second type limiting opening 310b, and third type limiting opening 310c, the second opening region 312 is formed, thereby making it possible to increase the light transmittance of the display panel 10.

[0073] There are several arrangements of the first type sub-pixels 400a, the second type sub-pixels 400b, and the third type sub-pixels 400c. For example, the first type sub-pixels 400a and the third type sub-pixels 400c are alternately arranged along the first direction Y to form a first pixel row R1, a plurality of second type sub-pixels 400b are sequentially arranged along the first direction Y to form a second pixel row R2, the first pixel row R1 and the second pixel row R2 are alternately arranged along the second direction Z, the first type sub-pixels 400a and the third type sub-pixels 400c are alternately arranged along the second direction Z to form a first pixel column C1, and a plurality of second type sub-pixels 400b are sequentially arranged along the second direction Z to form a second pixel column C2.

[0074] Preferably, the first pixel columns C1 and the second pixel columns C2 are also alternately arranged along the first direction Y, which makes the distribution of the sub-pixels 400 of different colors more uniform and improves the light output efficiency of the display panel 10.

[0075] Preferably, the second opening region 312 may be located between the first type sub-pixel 400a and the third type sub-pixel 400c that are adjacent to each other along the first direction Y and / or the second direction Z, respectively.

[0076] In these preferred embodiments, when a plurality of sub-pixels 400 are arranged to form a first pixel row R1, a second pixel row R2, a first pixel column C1, and a second pixel column C2, the corresponding plurality of first limiting apertures 310 are also arranged in the above manner. In the above arrangement, the spacing between adjacent first-type sub-pixels 400a and third-type sub-pixels 400c is usually large, and second aperture regions 312 are correspondingly provided between adjacent first-type sub-pixels 400a and third-type sub-pixels 400c along the first direction Y and / or the second direction Z, thereby appropriately increasing the distribution area of ​​the second aperture regions 312 and facilitating the improvement of the light transmittance of the display panel 10.

[0077] Preferably, the orthogonal projection area of ​​the second type sub-pixel 400b on the substrate 100 is smaller than the orthogonal projection area of ​​the first type sub-pixel 400a on the substrate 100. Preferably, the orthogonal projection area of ​​the second type sub-pixel 400b on the substrate 100 is smaller than the orthogonal projection area of ​​the third type sub-pixel 400c on the substrate 100.

[0078] In these preferred embodiments, the area of ​​the second type sub-pixels 400b is relatively small, i.e., the distribution area of ​​the green sub-pixels 400 is relatively small, and the distribution areas of the blue sub-pixels 400 and the red sub-pixels 400 are relatively large, which can improve the light output efficiency.

[0079] Furthermore, when the area of ​​the second-type sub-pixel 400b is relatively small, the distance between the second-type sub-pixel 400b and the first-type sub-pixel 400a and between the second-type sub-pixel 400b and the third-type sub-pixel 400c is relatively small, and the distance between the first-type sub-pixel 400a and the third-type sub-pixel 400c is relatively large, which makes it easy to provide the second opening region 312 between the first-type sub-pixel 400a and the third-type sub-pixel 400c.

[0080] In some preferred embodiments, as shown in Figures 13 and 14, the first type limiting opening 310a and the third type limiting opening 310c each have a first opening region 311 and a second opening region 312, and some of the second opening regions 312 are provided in the first type limiting opening 310a, and other parts of the second opening regions 312 are provided in the third type limiting opening 310c.

[0081] In these preferred embodiments, the first opening region 311 and the second opening region 312 are provided in the first type limiting opening 310a and the third type limiting opening 310c. The second opening region 312 is located between the first type limiting opening 310a and the third type limiting opening 310c. By providing some of the second opening regions 312 in the first type limiting opening 310a and other parts of the second opening regions 312 in the third type limiting opening 310c, the light transmittance of the display panel 10 can be increased and the configuration of the isolation structure 300 can be simplified.

[0082] Preferably, the multiple second opening regions 312 are provided at intervals around the periphery of the first opening region 311 of the first-type limiting opening 310a. For example, two second opening regions 312 are provided on both sides of the first-type limiting opening 310a, or four second opening regions 312 are provided on both sides of the first-type limiting opening 310a in the first direction Y and the second direction Z. That is, two second opening regions 312 are located on both sides of the first opening region 311 of the first-type limiting opening 310a in the first direction Y, and / or two second opening regions 312 are located on both sides of the first opening region 311 of the first-type limiting opening 310a in the second direction Z. By providing multiple second opening regions 312 within the same first-type limiting opening 310a, it is possible to further increase the light transmittance.

[0083] Preferably, a second opening area 312 is provided on both one side in the first direction Y and one side in the second direction Z of the first type limiting opening 310a of the first opening area 311, thereby further increasing the distribution area of ​​the second opening area 312.

[0084] Preferably, the multiple second opening regions 312 are provided at intervals around the periphery of the first opening region 311 of the third type limiting opening 310c. For example, two second opening regions 312 are provided on both sides of the third type limiting opening 310c, or four second opening regions 312 are provided on both sides of the third type limiting opening 310c in the first direction Y and the second direction Z. That is, two second opening regions 312 are located on both sides of the first opening region 311 of the third type limiting opening 310c in the first direction Y, and / or two second opening regions 312 are located on both sides of the first opening region 311 of the third type limiting opening 310c in the second direction Z. By providing multiple second opening regions 312 within the same third type limiting opening 310c, it is possible to further increase the light transmittance.

[0085] Preferably, a second opening area 312 is provided on both one side in the first direction Y and one side in the second direction Z of the first opening area 311 of the third type limiting opening 310c, thereby further increasing the distribution area of ​​the second opening area 312.

[0086] As shown in FIG. 15, in some other preferred embodiments, the second type limiting opening 310b has a first opening region 311 and a second opening region 312, and at least one second opening region 312 is provided in the second type limiting opening 310b and is located on at least one side of the first opening region 311 of the second type limiting opening 310b in the first direction Y and / or the second direction Z.

[0087] In these preferred embodiments, a second aperture region 312 may be provided within the second type limiting aperture 310b.

[0088] Preferably, the first pixel row R1 and the second pixel row R2 are arranged to be offset from each other, and the first pixel column C1 and the second pixel column C2 are arranged to be offset from each other, so that the second type sub-pixel 400b can be located between the corresponding first type sub-pixel 400a and the corresponding third type sub-pixel 400c adjacent to each other along the first direction Y and / or the second direction Z. That is, the second type limiting opening 310b is located between the corresponding first type limiting opening 310a and the corresponding third type limiting opening 310c adjacent to each other along the first direction Y and / or the second direction Z.

[0089] When the second opening region 312 is located between the first type limiting opening 310a and the third type limiting opening 310c adjacent to each other in the first direction Y and / or the second direction Z, the second opening region 312 is located on one side of the second type limiting opening 310b in the first direction Y and / or the second direction Z. In the embodiment of the present application, the second opening region 312 is provided within the second type limiting opening 310b, which can also simplify the distribution of the isolation structures 300.

[0090] Preferably, when the second type limiting opening 310b has the second opening region 312, the first type limiting opening 310a or the third type limiting opening 310c may also have the second opening region 312.

[0091] For example, the first type limiting opening 310a and the second type limiting opening 310b have a first opening region 311 and a second opening region 312, and at least one second opening region 312 is provided in the second type limiting opening 310b and is located on at least one side in the second direction Z of the first opening region 311 of the second type limiting opening 310b, and at least one second opening region 312 is provided in the first type limiting opening 310a and is located on at least one side in the second direction Z of the first opening region 311 of the first type limiting opening 310a.

[0092] In these preferred embodiments, the first type limiting aperture 310a and the second type limiting aperture 310b each have a second aperture region 312, which further increases the distribution area of ​​the second aperture region 312 and improves the light transmittance of the display panel 10.

[0093] Preferably, the third type limiting opening 310c has a first opening region 311 and a second opening region 312, and at least one second opening region 312 is provided in the third type limiting opening 310c and is located on at least one side of the first opening region 311 of the third type limiting opening 310c in the second direction Z.

[0094] In these preferred embodiments, the first type limiting aperture 310a, the second type limiting aperture 310b, and the third type limiting aperture 310c all have second aperture regions 312, which further increases the distribution area of ​​the second aperture regions 312 and improves the light transmittance of the display panel 10.

[0095] Preferably, the two second opening regions 312 are located on both sides of the first opening region 311 of the first type limiting opening 310a in the second direction Z. The first type limiting opening 310a has two second opening regions 312, which are symmetrically distributed with respect to the first opening region 311 of the first type limiting opening 310a, thereby simplifying the distribution shape of the isolation structure 300.

[0096] Preferably, the second opening region 312 includes a first-type light-transmitting region 312a located between the first-type sub-pixel 400a and the third-type sub-pixel 400c adjacent to each other in the first direction Y, and the first-type light-transmitting region 312a is provided in the third-type limiting opening 310c. The second opening region 312 between the first-type sub-pixel 400a and the third-type sub-pixel 400c adjacent to each other in the first direction Y is provided on one side of the third-type sub-pixel 400c in the second direction Z. By providing the first-type light-transmitting region 312a in the second-type limiting opening 310b, the distribution shape of the isolation structure 300 can be simplified.

[0097] Preferably, the second opening region 312 includes a second-type light-transmitting region 312b located between the first-type sub-pixel 400a and the second-type sub-pixel 400b adjacent to each other along the second direction Z, and the second-type light-transmitting region 312b is located in the first-type limiting opening 310a and / or the third-type limiting opening 310c. The second-type light-transmitting region 312b is located on one side of the first-type limiting opening 310a and / or the second-type limiting opening 310b in the first direction Y. By providing the second-type light-transmitting region 312b in the first-type limiting opening 310a and / or the second-type limiting opening 310b, the distribution shape of the isolation structure 300 can be simplified.

[0098] In some other preferred embodiments, as shown in FIG. 16, second opening areas 312 are provided on both sides of the first opening area 311 of the second type limiting opening 310b in the first direction Y and the second direction Z.

[0099] In these preferred embodiments, the plurality of second opening regions 312 are all provided in the second type limiting opening 310b, and the first type limiting opening 310a and the third type limiting opening 310c do not need to have second opening regions 312, which allows the shapes of the first type limiting opening 310a and the third type limiting opening 310c to be simplified.

[0100] 17 , the display panel 10 may further include a touch electrode 600, which may be provided on a side of the encapsulation layer 500 that is away from the substrate 100. The orthogonal projection of the touch electrode 600 on the substrate 100 is located within the orthogonal projection of the isolation structure 300 on the substrate 100.

[0101] In this preferred embodiment, the touch electrode 600 can be connected to a touch signal line of the display panel 10 to receive a touch signal, and can thereby be used to realize a touch-sensing operation of the display panel 10. By ensuring that the orthogonal projection of the touch electrode 600 on the substrate 100 is within the orthogonal projection of the isolation structure 300 on the substrate 100, the touch electrode 600 is less likely to block the first opening region 311 and the second opening region 312 in the thickness direction X of the display panel 10. As a result, light passing through the first opening region 311 and the second opening region 312 of the display panel 10 is less likely to be blocked by the touch electrode 600, and the light transmittance of the display panel 10 can be improved.

[0102] Preferably, the minimum spacing between the touch electrode 600 and the first opening area 311 on one side thereof may be equal to the minimum spacing between the touch electrode 600 and the first opening area 311 on the other side thereof, and / or the minimum spacing between the touch electrode 600 and the second opening area 312 on one side thereof may be equal to the minimum spacing between the touch electrode 600 and the second opening area 312 on the other side thereof, so that the touch electrode 600 can be positioned closer to the center above the isolation structure 300, and its shading influence on the light emitted by the sub-pixels 400 in the pixel openings 210 on both sides thereof can be closer, thereby effectively improving the color shift difference of the display panel 10.

[0103] Preferably, the material of the isolation structure 300 includes a conductive material, and at least a portion of the second electrodes 430 can be located within the first limiting opening 310 and connected to the isolation structure 300, so that the second electrodes 430 between adjacent subpixels 400 can be electrically connected by the isolation structure 300, i.e., the second electrodes 430 within adjacent first limiting openings 310 can be electrically connected to each other by the isolation structure 300 to form a plane electrode, thereby making it easier to control the second electrodes 430 in the display panel 10.

[0104] In some embodiments of the present application, the second opening region 312 may be a light-transmitting opening formed by recessing a surface facing one side of the first opening region 311 of the isolation structure 300, thereby allowing the light-transmitting structure for transmitting light in the embodiments of the present application (i.e., the second opening region 312) to be moved to the periphery of the first opening region 311. Compared to the related art in which a light-transmitting structure (e.g., a light-transmitting opening) that is not connected to the first opening region 311 is provided in the isolation structure 300, the isolation structure 300 of the display panel 10 in the embodiments of the present application is less likely to be blocked by multiple spaced apart portions due to the light-transmitting structure for transmitting light, thereby improving the convenience of the arrangement of the isolation structure 300 and making it easier for the second electrodes 430 of adjacent sub-pixels 400 to achieve electrical connection through the isolation structure 300.

[0105] 1 to 13, in some preferred embodiments, the isolation structure 300 includes a first isolation segment 320 and a second isolation segment 330 connected to each other, the width of the first isolation segment 320 is smaller than the width of the second isolation segment 330, and the first isolation segment 320 is located on one side of the second opening region 312. The relatively small width of the first isolation segment 320 can increase the distribution area of ​​the second opening region 312.

[0106] Preferably, the first isolation segment 320 and a portion of the second isolation segment 330 are enclosed to form the second open area 312 .

[0107] Preferably, the second electrode 430 can be overlap-connected to the first isolation segment 320 and some of the second isolation segments 330 simultaneously, thereby increasing the overlap connection area between the second electrode 430 and the isolation structure 300 and reducing the contact resistance between the second electrode 430 and the isolation structure 300.

[0108] Alternatively, as described above, the second electrode 430 is provided with a third lightening opening 431, and the second electrode 430 and the first isolation segment 320 are spaced apart at the location of the third lightening opening 431, and the second electrode 430 and the second isolation segment 330 are overlapping and connected to each other, thereby further improving the light transmittance of the display panel.

[0109] Preferably, the width of the first isolated segment 320 may refer to the spacing distance between the surfaces of the first isolated segment 320 facing the first opening region 311 on both sides thereof, for example, the width of the first isolated segment 320 may refer to the maximum spacing distance between the surfaces of the first isolated segment 320 facing the first opening region 311 on both sides thereof. Preferably, the width of the second isolated segment 330 may refer to the spacing distance between the surfaces of the second isolated segment 330 facing the first opening region 311 on both sides thereof, for example, the width of the second isolated segment 330 may refer to the maximum spacing distance between the surfaces of the second isolated segment 330 facing the first opening region 311 on both sides thereof.

[0110] Preferably, the width of the first isolation portion 301 of the first isolation segment 320 may be smaller than the width of the first isolation portion 301 of the second isolation segment 330. Preferably, the width of the second isolation portion 302 of the first isolation segment 320 may be smaller than the width of the second isolation portion 302 of the second isolation segment 330. Preferably, the width of the third isolation portion 303 of the first isolation segment 320 may be smaller than the width of the third isolation portion 303 of the second isolation segment 330.

[0111] The width of the first isolation portion 301 may refer to the distance between the surfaces of the first isolation portion 301 facing the first opening region 311 on both sides thereof, for example, the maximum distance between the surfaces of the first isolation portion 301 facing the first limiting opening 310 on both sides thereof. The width of the second isolation portion 302 may refer to the distance between the surfaces of the second isolation portion 302 facing the first opening region 311 on both sides thereof, for example, the maximum distance between the surfaces of the second isolation portion 302 facing the first opening region 311 on both sides thereof. The width of the third isolation portion 303 may refer to the distance between the surfaces of the third isolation portion 303 facing the first opening region 311 on both sides thereof, for example, the maximum distance between the surfaces of the third isolation portion 303 facing the first opening region 311 on both sides thereof.

[0112] Preferably, the first isolation segment 320 is connected between two adjacent second isolation segments 330 , and the second open area 312 is formed between the adjacent second isolation segments 330 .

[0113] In these preferred embodiments, by making the width of the first isolation segment 320 smaller than the width of the second isolation segment 330, the isolation structure 300 can be recessed at the first isolation segment 320 with a relatively narrow width between two adjacent second isolation segments 330 to form a second opening area 312, so that light can effectively pass through the second opening area 312 and transmit through the display panel 10, thereby effectively improving the light transmittance of the display panel 10.

[0114] 13 , in some preferred embodiments, there is a first spacing distance G1 between at least two adjacent pixel openings 210, and there is a second spacing distance G2 between at least two adjacent pixel openings 210, where the first spacing distance G1 is greater than the second spacing distance G2. That is, there is a first spacing distance G1 and a second spacing distance G2 between two different adjacent pixel openings 210, where the first spacing distance G1 is greater than the second spacing distance G2. In this document, the first spacing distance G1 is the first spacing in the priority document, and the second spacing distance G2 is the second spacing in the priority document.

[0115] Preferably, the first spacing distance G1 being greater than the second spacing distance G2 may mean that the minimum spacing distance between two adjacent pixel openings 210 corresponding to the first spacing distance G1 is greater than the minimum spacing distance between two adjacent pixel openings 210 corresponding to the second spacing distance G2.

[0116] Preferably, the second opening area 312 may be located at the first gap distance G1.

[0117] Preferably, the first isolation segment 320 may be located at a first spacing distance G1.

[0118] In these preferred embodiments, the second opening region 312 and the first isolation segment 320 are disposed at a first spacing G1 having a relatively large dimension, i.e., by disposing the second opening region 312 and the first isolation segment 320 between adjacent pixel openings 210 having a relatively large spacing, a second opening region 312 having a relatively large dimension can be disposed between adjacent pixel openings 210 having a relatively large spacing, thereby favorably improving the light transmittance of the display panel 10. Furthermore, this also makes it difficult for the location of the second opening region 312 to affect the dimension of the spacing structure between pixel openings 210 having a relatively small spacing. For example, by disposing the second isolation segment 330 at a second spacing G2, a relatively wide isolation structure 300 can be disposed between pixel openings 210 having a relatively small spacing, thereby reducing resistance.

[0119] In some preferred embodiments, there is a third spacing distance G3 between at least two adjacent pixel openings 210, where the first spacing distance G1 is greater than the third spacing distance G3 and the third spacing distance G3 is not equal to the second spacing distance G2. Wherein, the first spacing distance G1 being greater than the third spacing distance G3 and the third spacing distance G3 not equal to the second spacing distance G2 may mean that the minimum spacing distance between two adjacent pixel openings 210 corresponding to the first spacing distance G1 is greater than the minimum spacing distance between two adjacent pixel openings 210 corresponding to the third spacing distance G3 and the minimum spacing distance between two adjacent pixel openings 210 corresponding to the third spacing distance G3 is not equal to the minimum spacing distance between two adjacent pixel openings 210 corresponding to the second spacing distance G2.

[0120] Preferably, the second isolation segments 330 are provided at a third spacing distance G3, which allows for a relatively wide isolation structure 300 between pixel openings 210 with a relatively small spacing distance, thereby reducing resistance.

[0121] Preferably, the pixel opening 210 includes a first opening 211, a second opening 212, and a third opening 213, among which, for example, the first type sub-pixel 400a may be at least partially located in the first opening 211, the second type sub-pixel 400b may be at least partially located in the second opening 212, and the third type sub-pixel 400c may be at least partially located in the third opening 213.

[0122] Preferably, there is a first spacing distance G1 between adjacent first openings 211 and third openings 213, a second spacing distance G2 between adjacent first openings 211 and second openings 212, and a third spacing distance G3 between adjacent second openings 212 and third openings 213; that is, the spacing distance between adjacent first openings 211 and third openings 213 may be greater than the spacing distance between adjacent first openings 211 and second openings 212, and may also be greater than the spacing distance between adjacent second openings 212 and third openings 213.

[0123] Preferably, the second opening region 312 may be located between the first opening 211 and the third opening 213 .

[0124] Preferably, the first isolation segment 320 may be located between the first opening 211 and the third opening 213 .

[0125] In these preferred embodiments, by providing the second opening region 312 and the first isolation segment 320 between the first opening 211 and the third opening 213 having a relatively large spacing distance, the second opening region 312 having a relatively large dimension can be arranged between adjacent pixel openings 210 having a relatively large spacing distance, thereby effectively improving the light transmittance of the display panel 10.

[0126] In some embodiments of the present application, there are multiple arrangements between the pixel apertures 210.

[0127] In some preferred embodiments, the first openings 211 and the third openings 213 may be alternately arranged along the first direction Y to form a first pixel column C1, and the plurality of second openings 212 may be arranged at intervals along the first direction Y to form a second pixel column C2.

[0128] Preferably, the first pixel columns C1 and the second pixel columns C2 are arranged alternately in the second direction Z.

[0129] Preferably, the second opening region 312 may be located in the first pixel column C1.

[0130] Preferably, the first isolated segment 320 may be located in the first pixel column C1.

[0131] In these preferred embodiments, by providing the second opening region 312 and the first isolation segment 320 in the first pixel column C1, the second opening region 312 having a relatively large dimension can be arranged in the first pixel column C1 having a relatively large spacing distance between adjacent pixel openings 210, which can effectively improve the light transmittance of the display panel 10.

[0132] In some preferred embodiments, the first openings 211 and the third openings 213 are alternately arranged along the second direction Z to form a first pixel row R1, and the plurality of second openings 212 are arranged at intervals along the second direction Z to form a second pixel row R2.

[0133] Preferably, the first pixel rows R1 and the second pixel rows R2 are arranged alternately in the first direction Y.

[0134] Preferably, the second opening region 312 is located in the first pixel row R1.

[0135] Preferably, the first isolated segment 320 is located in the first pixel row R1.

[0136] In these preferred embodiments, by providing the second opening region 312 and the first isolation segment 320 in the first pixel row R1, the second opening region 312 having a relatively large dimension can be arranged in the first pixel row R1 having a relatively large spacing distance between adjacent pixel openings 210, which can effectively improve the light transmittance of the display panel 10.

[0137] Preferably, as discussed above, the isolation structure 300 comprises a first isolation segment 320 and a second isolation segment 330 .

[0138] Preferably, as described above, communication holes 161 are opened in the planarization layer 160, and at least some of the communication holes 161 may be spaced apart along a straight line in the arrangement direction of the subpixels 400. For example, the communication holes 161 may be spaced apart along a straight line in the first direction Y and / or the second direction Z. As a result, since the communication holes 161 are arranged below the isolation structure 300, the edge portion of the isolation structure 300 facing the first limiting opening 310 is less likely to be recessed downward due to the arrangement of the communication holes 161.

[0139] As shown in FIG. 18, preferably, a receiving groove 220 is formed in the pixel limiting portion 200, and at least a portion of the isolation structure 300 may be located within the receiving groove 220. This prevents the isolation structure 300 from having an excessively large height relative to the substrate 100, and effectively reduces the thickness of the display panel 10.

[0140] As shown in FIGS. 1 to 18 , an embodiment of a first aspect of the present application provides a display panel 10 including a substrate 100, an isolation structure 300 provided on one side of the substrate 100 and enclosing it to form a first opening region 311, and sub-pixels 400, at least a portion of which is located within the first opening region 311, wherein at least a portion of the isolation structure 300 is provided on a side facing the first opening region 311 with a second opening region 312 communicating with the first opening region 311, and the second opening region 312 is provided through the isolation structure 300 in the thickness direction X of the display panel 10.

[0141] The display panel 10 according to the embodiment of the present application includes a substrate 100, an isolation structure 300, and sub-pixels 400. The isolation structure 300 is disposed on one side of the substrate 100 and encloses a first opening region 311, at least a portion of the sub-pixels 400 being located within the first opening region 311, and the isolation structure 300 can be used to partition the sub-pixels 400 of the display panel 10. At least a portion of the isolation structure 300 has a second opening region 312 communicating with the first opening region 311 on the side facing the first opening region 311, the second opening region 312 penetrating the isolation structure 300 in the thickness direction X of the display panel 10, thereby allowing light to efficiently transmit through the display panel 10 through the second opening region 312 in the thickness direction X of the display panel 10 and improving the light transmittance of the display panel 10.

[0142] Preferably, the second opening area 312 is located on both sides of the first isolation segment 320 toward the first opening area 311, which can effectively increase the arrangement density of the second opening area 312 and further improve the light transmission performance of the display panel 10.

[0143] As shown in FIGS. 2 and 3, in some preferred embodiments, the display panel 10 further includes a pixel limiting portion 200 that encloses and defines a pixel aperture 210, and the sub-pixel 400 may be partially located within the pixel aperture 210.

[0144] Preferably, the bonding surface between the first electrode 410 and the light-emitting unit 420 of the sub-pixel 400 may be located within the pixel opening 210, so that the light-emitting unit 420 within the pixel opening 210 can emit light and display well.

[0145] Preferably, the pixel opening 210 can communicate with the first opening region 311. For example, the orthogonal projection of the pixel opening 210 on the substrate 100 is located within the orthogonal projection of the first opening region 311 on the substrate 100, so that the materials of the light-emitting unit 420 and the second electrode 430 can easily pass through the first opening region 311 and enter the pixel opening 210, thereby effectively increasing the amount of the materials of the light-emitting unit 420 and the second electrode 430 that enter the pixel opening 210. The orthogonal projection of the first opening region 311 on the substrate 100 may also refer to the projection area formed by orthogonally projecting the inner wall of the first opening region 311 on the substrate 100. The orthogonal projection of the pixel opening 210 on the substrate 100 may also refer to the projection area formed by orthogonally projecting the inner wall of the pixel opening 210 on the substrate 100.

[0146] Preferably, the second opening region 312 is located on the side of the pixel limiting portion 200 that is away from the substrate 100. Preferably, the orthogonal projection of the pixel opening 210 on the substrate 100 does not overlap with the orthogonal projection of the second opening region 312 on the substrate 100, so that the second isolation segment 330 that encloses and forms the second opening region 312 is unlikely to block the emission of the sub-pixels 400 within the pixel opening 210.

[0147] Preferably, the material of the pixel limiting portion 200 may include an insulating material.

[0148] In these preferred embodiments, the pixel limiting portion 200 can also be used to define the sub-pixels 400 of the display panel 10. The pixel limiting portion 200 may be located between the first electrodes 410 of adjacent sub-pixels 400, thereby providing insulation between the first electrodes 410 of adjacent sub-pixels 400 through the pixel limiting portion 200. The pixel limiting portion 200 may also be located between the isolation structure 300 and the first electrode 410, thereby providing insulation between the isolation structure 300 and the first electrode 410 through the pixel limiting portion 200, and preventing short-circuiting between the second electrode 430 and the first electrode 410 due to the isolation structure 300.

[0149] Preferably, the minimum spacing distance between the orthogonal projection of the first isolation segment 320 on the substrate 100 and the orthogonal projection of the pixel opening 210 on the substrate 100 is greater than the minimum spacing distance between the orthogonal projection of the second isolation segment 330 on the substrate 100 and the orthogonal projection of the pixel opening 210 on the substrate 100, so that the first isolation segment 320 can be recessed relative to the second isolation segment 330 in a direction away from the pixel opening 210 to effectively form a large-sized second opening area 312, thereby further improving the light transmittance of the display panel 10.

[0150] In some embodiments of the present application, there are several ways to set the relative positions between the isolation structure 300 and the pixel limiting portion 200 .

[0151] In some preferred embodiments, as shown in FIGS. 2 and 3 , the isolation structure 300 is provided on the side of the pixel limiting portion 200 that is away from the substrate 100, i.e., the isolation structure 300 may be provided directly on the pixel limiting portion 200.

[0152] As shown in Figures 1 to 5, in some preferred embodiments, the orthogonal projection of the first electrode 410 on the substrate 100 may at least partially overlap with the orthogonal projection of the isolation structure 300 on the substrate 100, so that the first electrode 410 can be partially positioned below the isolation structure 300 and can effectively extend below the isolation structure 300 via the edge portion of the isolation structure 300 facing the first limiting opening 310, and the film layer structure below the edge portion of the isolation structure 300 facing the first limiting opening 310 can be flat. When the isolation structure 300 is fabricated by etching, abnormal etching of the edge portion of the isolation structure 300 by the etching material is unlikely to occur, which can effectively improve the fabrication yield of the isolation structure 300. Furthermore, this also makes the second electrode 430 above the first electrode 410 less affected by the positioning of the first electrode 410, and the second electrode 430 can be gently connected to the edge portion of the isolation structure 300 toward the first limiting opening 310, thereby significantly improving the reliability of the connection between the second electrode 430 and the isolation structure 300.

[0153] In some embodiments of the present application, the substrate 100 may be provided in a variety of ways. For example, the substrate 100 may include a substrate 110 and a driving circuit 150 provided on the substrate 110. For example, the driving circuit 150 may include a transistor 151, a storage capacitor 152, and driving signal lines for connecting each element. The transistor 151 includes a semiconductor, a gate electrode 151a, and a source / drain electrode 151b. The storage capacitor 152 includes a first electrode plate 152a and a second electrode plate 152b.

[0154] Preferably, the substrate 100 includes a first insulating layer 120, a second insulating layer 130, and a third insulating layer 140, which are stacked one on the other. As an example, the gate electrode 151a and the first electrode plate 152a may be located on the side of the first insulating layer 120 facing the substrate 110, the second electrode plate 152b may be located between the first insulating layer 120 and the second insulating layer 130, and the source / drain electrode 151b may be located between the second insulating layer 130 and the third insulating layer 140.

[0155] Preferably, the substrate 100 further comprises a planarization layer 160 provided on the side of the transistor 151 facing the subpixel 400, for example, the planarization layer 160 may be provided on the side of the third insulating layer 140 facing away from the substrate 100.

[0156] Preferably, a through hole 161 may be opened in the planarization layer 160, and the first electrode 410 can be connected to the transistor 151 through the through hole 161, for example, the first electrode 410 can be connected to the source-drain electrode 151b of the transistor 151 through the through hole 161.

[0157] Preferably, the orthogonal projection of the through hole 161 on the substrate 100 may be located within the orthogonal projection of the isolation structure 300 on the substrate 100. That is, the through hole 161 may be located below the isolation structure 300, rather than on the side facing the first limiting opening 310 of the isolation structure 300. This makes it less likely that the edge portions of the isolation structure 300 facing the first opening region 311 and the second opening region 312 will be recessed downward due to the arrangement of the through hole 161. When the isolation structure 300 is fabricated by etching, the etching material is less likely to cause abnormal etching of the edge portions of the isolation structure 300, which can improve the fabrication yield of the isolation structure 300. Furthermore, this also makes the second electrode 430 above the first electrode 410 less affected by the arrangement of the communication holes 161, and the second electrode 430 can be gently connected to the edge portion of the isolation structure 300 toward the first limiting opening 310, thereby effectively improving the reliability of the connection between the second electrode 430 and the isolation structure 300.

[0158] The orthogonal projection of the communication hole 161 onto the substrate 100 may refer to a projection area formed by orthogonal projection of the inner wall of the communication hole 161 onto the substrate 100, which is enclosed and closed.

[0159] As shown in FIG. 5, in some preferred embodiments, a second conductive layer 412 is provided on the side of the first electrode 410 facing away from the substrate 100 .

[0160] Preferably, the orthogonal projection of the first electrode 410 on the substrate 100 is located within the orthogonal projection of the second conductive layer 412 on the substrate 100 .

[0161] Preferably, the orthogonal projection of the first electrode 410 on the substrate 100 may be located within the orthogonal projection of the pixel aperture 210 on the substrate 100 .

[0162] In these preferred embodiments, the first electrode 410 can be used mainly as the anode of the display panel 10, and the second conductive layer 412 located above the first electrode 410 can be used to protect the first electrode 410 from being destroyed when other film layers are patterned in the process steps of fabricating the display panel 10. For example, when other film layers are etched, the second conductive layer can be used to prevent the first electrode 410 from being etched by the etching material, thereby allowing the first electrode 410 to have good structural stability.

[0163] In some preferred embodiments, the optical transmittance of the second conductive layer 412 is greater than the optical transmittance of the first electrode 410 .

[0164] Preferably, the material of the second conductive layer 412 includes at least one of indium tin oxide, indium zinc oxide, or zinc oxide.

[0165] Preferably, the material of the first electrode 410 may include a metal material, for example, the material of the first electrode 410 may include silver, so that the first electrode 410 can have a certain reflective ability to reflect the light emitted by the light-emitting unit 420 above the first electrode 410, and can well improve the display brightness of the display panel 10.

[0166] In these preferred embodiments, by making the light transmittance of the second conductive layer 412 greater than that of the first electrode 410, the second conductive layer 412 is less likely to have an excessive effect on the propagation of light rays, and light rays can be effectively transmitted through the second conductive layer 412, thereby effectively improving the light transmission performance of the display panel 10.

[0167] Preferably, the substrate 100 includes the transistor 151, and the connection portion 411 and the second conductive layer 412 are provided in the same layer and can be connected to the transistor 151, so that the first electrode 410 can be electrically connected to the transistor 151 on the substrate 100 via the second conductive layer 412 and the connection portion 411. The small size of the first electrode 410 reduces the shading effect of the first electrode 410 on light rays and effectively improves the light transmission performance of the display panel 10. Furthermore, the light transmittance of the second conductive layer 412 is greater than that of the first electrode 410, i.e., the second conductive layer 412 is also unlikely to have an excessive shading effect on the propagation of light rays. Therefore, the second conductive layer 412 can be set to a large size so as to be connected to the transistor 151 via the connection portion 411.

[0168] In some embodiments of the present application, there are several ways to arrange the second opening region 312 and the first isolated segment 320. Among them, the arrangement of the second opening region 312 and the first isolated segment 320 can be set based on the spacing distance between each adjacent pixel opening 210.

[0169] 13 , the first opening region 311 preferably includes a first-type first opening region 311 and a second-type first opening region 311, wherein at least a portion of the first-type sub-pixel 400a may be located within the first-type first opening region 311, and at least a portion of the second-type sub-pixel 400b may be located within the second-type first opening region 311. That is, the first limiting opening 310 includes a first-type limiting opening 310a and a second-type limiting opening 310b, wherein at least a portion of the first-type sub-pixel 400a may be located within the first-type limiting opening 310a, and at least a portion of the second-type sub-pixel 400b may be located within the second-type limiting opening 310b.

[0170] Preferably, the first opening region 311 may further include a third type first opening region 311, and at least a portion of the third type sub-pixel 400c may be located within the third type first opening region 311. That is, the first limiting opening 310 may further include a third type limiting opening 310c, and at least a portion of the third type sub-pixel 400c may be located within the third type limiting opening 310c.

[0171] In some embodiments of the present application, the second opening regions 312 may be provided on the circumferential side of some specific first opening regions 311. Preferably, there may be a plurality of second opening regions 312, and the plurality of second opening regions 312 may be provided at intervals on the circumferential side of at least some of the first opening regions 311, thereby uniformly improving the light transmittance on the circumferential side of the first opening regions 311.

[0172] In some preferred embodiments, at least a portion of the second aperture region 312 may be located in the first-type limiting aperture 310a, and the first-type limiting aperture 310a having the second aperture region 312 forms the first light-transmitting region 30a of the isolation structure 300, so that the display panel 10 in the first light-transmitting region 30a can have good light transmittance.
