DETAILED DESCRIPTION

[0061] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the present application. However, it will be apparent to those skilled in the art that the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating the examples of the present application.

[0062] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0063] After research, the inventors found that the reason why there is a signal crosstalk problem between the signal lines arranged along the thickness direction of the display panel in the display panel is that: in order to ensure the transmittance of the display panel, the opaque film layer in the display panel is designed with openings to improve the transmittance of the display panel. Due to the presence of the openings, the film layer loses its shielding effect at the opening position, and the signal lines located on the upper and lower sides of the opening are prone to crosstalk at the opening, thereby affecting the performance of the display panel. Based on the research on the above problems, the inventors provide a display panel and a display device to improve the signal crosstalk problem in the display panel and improve the performance of the display panel. Patent PCT / CN2023 / 134518, Patent 202310759370.2, Patent 202310740412.8, Patent 202310707209.0 and Patent 202311346196.5 record the relevant technical solutions of the isolation structure, and their contents are incorporated into this application by reference for reference and will not be repeated in this embodiment.

[0064] In order to better understand this application, Figures 1 to 12 The display panel and the display device according to the embodiments of the present application are described in detail.

[0065] See also Figures 1 to 5The embodiment of the present application provides a display panel 1, comprising a substrate 11, a light-emitting layer 12, an isolation structure layer 13, and a touch layer 14. The light-emitting layer 12 is formed on one side of the substrate 11 and comprises a plurality of light-emitting units 120. The isolation structure layer 13 is formed on the side of the light-emitting layer 12 facing away from the substrate 11 and comprises an isolation structure 131, an opening 132, and a light-transmitting hole 133. The opening 132 and the light-transmitting hole 133 are enclosed by the isolation structure 131. The opening 132 is used to expose the light-emitting unit 120. The light-transmitting hole 133 is formed between at least part of adjacent openings 132. The orthographic projection of the portion of the isolation structure 131 enclosing the light-transmitting hole 133 on the substrate 11 comprises a first portion 1333 and a second portion 1334. The touch layer 14 comprises a touch sublayer 140. The orthographic projection of the touch sublayer 140 on the substrate 11 is located within the first portion 1333, and the orthographic projection of the touch sublayer 140 on the substrate 11 does not overlap with the second portion 1334.

[0066] The display panel 1 provided in the present application includes a substrate 11, a light-emitting layer 12, an isolation structure layer 13 and a touch layer 14. The light-emitting layer 12 includes a plurality of light-emitting units 120, and the light-emitting units 120 are used to emit light to realize the display function of the display panel 1. The isolation structure layer 13 is formed on the side of the light-emitting layer 12 away from the substrate 11. The isolation structure layer 13 includes an isolation structure 131, an opening 132 and a light-transmitting hole 133. The isolation structure 131 is an opaque area or an area with poor transparency. The isolation structure 131 encloses the opening 132 and the light-transmitting hole 133. The opening 132 is used to expose the light-emitting unit 120 to achieve light emission. The light-transmitting hole 133 is located between at least part of adjacent openings 132, that is, the orthographic projection of the light-transmitting hole 133 on the substrate 11 is located between the orthographic projections of at least part of the light-emitting units 120 on the substrate 11, thereby achieving light transmission in the area between adjacent light-emitting units 120 to improve the light transmittance of the display panel 1. The touch layer 14 is formed on the side of the isolation structure layer 13 away from the substrate 11. The touch layer 14 includes a touch sublayer 140. The signal in the touch sublayer 140 and the signal of the signal line in the substrate 11 are easily crosstalked through the light-transmitting hole 133. In the display panel 1 provided in the present application, the orthographic projection of the part of the isolation structure 131 that encloses the light-transmitting hole 133 on the substrate 11 includes a first part 1333 and a second part 1334. The orthographic projection of the touch sublayer 140 on the substrate 11 is located in the first part 1333, and the touch sublayer 140 is located on the substrate 11. The orthographic projection on substrate 11 does not overlap with the second portion 1334, that is, the touch sublayer 140 is arranged along the circumference of the light-transmitting hole 133 and surrounds a portion of the circumference of the light-transmitting hole 133, and a portion of the circumference of the light-transmitting hole 133 is not surrounded by the touch sublayer 140. This reduces the probability of crosstalk between the signal line in the touch sublayer 140 and the signal in substrate 11 below the hole area. In addition, the orthographic projection of the portion surrounding the light-transmitting hole 133 on substrate 11 is located within the orthographic projection of the first portion 1333 on substrate 11, and can be shielded by the first portion 1333. As a result, the crosstalk problem in the display panel 1 provided by the present application is improved, and the performance of the display panel 1 is enhanced. In the above embodiment, the orthographic projection of the touch sublayer 140 on the substrate 11 does not overlap with the orthographic projection of the light-transmitting hole 133 on the substrate 11, and the orthographic projection of the touch sublayer 140 on the substrate 11 does not overlap with the orthographic projection of the opening 132 on the substrate 11, thereby improving the mutual crosstalk between the signals in the touch sublayer 140 and the signals in the substrate 11.

[0067] In the above embodiment, if Figure 4As shown, the display panel 1 can be a transparent display panel 1. Alternatively, the display panel 1 includes a first display area AA1 and a second display area AA2. The first display area AA1 is provided with the aforementioned light-transmitting apertures 133, so that the light transmittance of the first display area AA1 is greater than that of the second display area AA2. A photosensitive module, such as a camera module or a fingerprint recognition module, can be disposed below the first display area AA1. The higher light transmittance of the first display area AA1 can improve the performance of the photosensitive module, thereby improving the performance of the display panel 1.

[0068] In one possible implementation, Figure 5 As shown, the width of the first portion 1333 is greater than the width of the second portion 1334 .

[0069] In the above embodiment, the width of the first portion 1333 is greater than the width of the second portion 1334. The larger width of the first portion 1333 facilitates better shielding of the touch sublayer 140 located on the side of the first portion 1333 facing away from the substrate 11. Since the touch sublayer 140 is not located on the side of the second portion 1334 facing away from the substrate 11, the width of the second portion 1334 can be smaller to increase the area of ​​the light-transmitting hole 133 and thus improve light transmittance.

[0070] In one possible implementation, Figure 3 As shown, the orthographic projection of the isolation structure 131 on the substrate 11 includes a first projection area 1311 and a second projection area 1312, the orthographic projection of the touch sublayer 140 on the substrate 11 is located in the first projection area 1311, and the orthographic projection of the touch sublayer 140 on the substrate 11 does not overlap with the second projection area 1312, and the width of the first projection area 1311 is greater than the width of the second projection area 1312.

[0071] In the above embodiment, the first projection area 1311 includes the portion of the isolation structure 131 enclosing the opening 132 in the orthographic projection onto the substrate 11, as well as the first portion 1333. The second projection area 1312 includes another portion of the isolation structure enclosing the opening 132 in the orthographic projection onto the substrate 11, as well as the second portion 1334. The first projection area 1311 can be used to shield the touch sublayer 140. Therefore, the width of the first projection area 1311 is relatively large, which can improve the shielding effect on the touch sublayer 140. The width of the second projection area 1312 is relatively small, which can increase the area of ​​the opening 132 and the light-transmitting hole 133, thereby increasing the aperture ratio, thereby improving the display effect, and increasing the light transmittance.

[0072] Specifically, the width of the first projection area 1311 and the second projection area 1312 refers to the distance between adjacent openings 132 , adjacent light-transmitting holes 133 , or adjacent openings 132 and light-transmitting holes 133 in the orthographic projection of the isolation structure 131 on the substrate 11 .

[0073] In the above embodiment, the distance between the edge of the orthographic projection of the touch sub-layer 140 on the substrate 11 and the edge of the first projection area 1311 is the first preset distance, and the first preset distance is 0-3 μm.

[0074] In the above embodiment, by setting the distance between the edge of the orthographic projection of the touch sublayer 140 on the substrate 11 and the edge of the first projected area 1311 to a first predetermined distance, and controlling the first predetermined distance to be between 0 and 3 μm, this can mitigate the problem of the orthographic projection of the touch sublayer 140 on the substrate 11 exceeding the boundary of the first projected area 1311 due to process variations. This can cause the orthographic projection of the touch sublayer 140 on the substrate 11 to overlap with the orthographic projection of the light-transmitting hole 133 on the substrate 11, thereby poorly shielding the touch sublayer 140 from the isolation structure 131 and causing interference between the signals within the touch sublayer 140 and the signals within the substrate 11. This design can mitigate the crosstalk problem between the signals within the touch sublayer 140 and the signals within the substrate 11. Furthermore, by setting the first predetermined distance to less than 3 μm, it can prevent the area of ​​the light-transmitting hole 133 from being affected by an excessively large first projected area 1311. Specifically, by reducing the area of ​​the first projected area 1311, the area of ​​the light-transmitting hole 133 can be increased, thereby improving light transmittance. Specifically, the first preset distance is 0um, 0.5um, 1.3um, 2.8um, 3um, etc., and this application does not impose any special limitation on this.

[0075] In a feasible implementation, the light emitting unit 120 includes a first light emitting unit 120 , a second light emitting unit 120 and a third light emitting unit 120 , and the first light emitting unit 120 , the second light emitting unit 120 and the third light emitting unit 120 have different colors.

[0076] Specifically, the first light emitting unit 120 may be a blue light emitting unit 120 , the second light emitting unit 120 may be a red light emitting unit 120 , and the third light emitting unit 120 may be a green light emitting unit 120 .

[0077] In one possible implementation, Figure 3 As shown, the opening 132 includes a first opening 1321, a second opening 1322 and a third opening 1323. The first opening 1321 exposes the first light emitting unit 120, the second opening 1322 exposes the second light emitting unit 120, and the third opening 1323 exposes the third light emitting unit 120. Figure 6As shown, the first openings 1321 and the second openings 1322 are alternately arranged along the first direction x to form a first opening row L1, and the first openings 1321 and the second openings 1322 are alternately arranged along the second direction y to form a first opening column A1, the first direction x intersects with the second direction y, and a plurality of third openings 1323 are arranged along the second direction y to form a second opening column A2, and the first opening column A1 and the second opening column A2 are alternately arranged along the first direction x.

[0078] In the above embodiment, the third light-emitting unit 120 is arranged around the first light-emitting unit 120, the third light-emitting unit 120 is arranged around the second light-emitting unit 120, and the first light-emitting unit 120 and the second light-emitting unit 120 are alternately arranged around the third light-emitting unit 120, thereby achieving a good light mixing effect and improving the light output quality of the display panel 1.

[0079] In one possible implementation, Figure 6 As shown, the light-transmitting hole 133 includes a first light-transmitting hole 1331 and a second light-transmitting hole 1332. The first light-transmitting hole 1331 is formed between the first opening 1321 and the second opening 1322 in the first opening row L1, and the second light-transmitting hole 1332 is formed between at least part of the first opening 1321 and the second opening 1322 in the first opening column A1.

[0080] Specifically, when the distance between at least some of the first openings 1321 and the second openings 1322 in the first opening row A1 is relatively short, the second light-transmitting hole 1332 may not be provided therebetween to ensure the manufacturing yield of the isolation structure 131 .

[0081] In one possible implementation, Figure 3 As shown, the first light-transmitting hole 1331 includes a first sub-hole 1335 and a second sub-hole 1336 arranged adjacent to each other, and a first sub-hole 1335 or a second sub-hole 1336 is formed between the adjacent first openings 1321 and the second openings 1322. The first sub-hole 1335 and the second sub-hole 1336 are symmetrical about the symmetry axis parallel to the second direction y, and the part of the isolation structure 131 surrounding the first sub-hole 1335 and the part surrounding the second sub-hole 1336 are symmetrical about the symmetry axis parallel to the second direction y.

[0082] In the above embodiment, the first light-transmitting hole 1331 includes a first sub-hole 1335 and a second sub-hole 1336. The first sub-hole 1335 and the second sub-hole 1336 are adjacently arranged along the first direction x, and a first opening 1321 or a second opening 1322 is provided between the first sub-hole 1335 and the second sub-hole 1336. The first sub-hole 1335 and the second sub-hole 1336 are symmetrical about an axis of symmetry parallel to the second direction y, and the portion of the isolation structure surrounding the first sub-hole 1335 and the portion surrounding the second sub-hole 1336 are symmetrical about the axis of symmetry parallel to the second direction y. This can simplify the patterning process for the isolation structure layer 13 and reduce production costs.

[0083] In one possible implementation, Figure 3 and Figure 7 As shown, three light-transmitting holes 133 are arranged around the first opening 1321, the touch sublayer 140 includes a mesh structure 1401, the mesh structure 1401 includes a first winding portion 1402 and a first discontinuous portion 1403, the first discontinuous portion 1403 and the first winding portion 1402 are arranged together around the first opening 1321, the first winding portion 1402 is arranged around part of the circumference of the first opening 1321, and the first discontinuous portion 1403 is located between the first opening 1321 and a light-transmitting hole 133.

[0084] In the above embodiment, all positions in the mesh structure 1401 are electrically connected to each other to form touch electrodes or touch traces.

[0085] In the above embodiment, if Figure 7 As shown, the mesh structure 1401 includes a first winding portion 1402 and a first discontinuous portion 1403. The first discontinuous portion 1403 and the first winding portion 1402 are arranged together around the first opening 1321. The first winding portion 1402 is arranged around a portion of the periphery of the first opening 1321, thereby ensuring the area of ​​the first winding portion 1402 to ensure the touch effect. The first discontinuous portion 1403 is located between the first opening 1321 and a light-transmitting hole 133. Therefore, the mesh structure 1401 is not arranged between the first opening 1321 and the light-transmitting hole 133, thereby reducing the range of the mesh structure 1401 surrounding the light-transmitting hole 133, thereby reducing the probability of crosstalk between the signal line in the touch sublayer 140 and the signal in the substrate 11 below the light-transmitting hole 13.

[0086] In the above embodiment, the first light emitting unit 120 is a blue light emitting unit 120 and the second light emitting unit 120 is a red light emitting unit 120 , or the first light emitting unit 120 is a red light emitting unit 120 and the second light emitting unit 120 is a blue light emitting unit 120 .

[0087] In the above embodiment, if Figure 7As shown, the mesh structure 1401 further includes a second winding portion 1404 , which connects two adjacent first winding portions 1402 , and the second winding portion 1404 partially circumferentially surrounds the third opening 1323 .

[0088] On the one hand, the second winding portion 1404 can achieve electrical connection with the adjacent first winding portion 1402 to achieve signal transmission; on the other hand, the second winding portion 1404 can ensure the area of ​​the mesh structure 1401 to ensure the touch effect; in addition, the touch sublayer 140 has a certain reflective effect on light. The portion of the second winding portion 1404 surrounding the third opening 1323 can reduce the reflection difference around the first opening 1321, the second opening 1322 and the third opening 1323 while exposing a portion of the third opening 1323 in the circumference. Specifically, the side of the third opening 1323 facing the light-transmitting hole 133 can be exposed to reduce the probability of crosstalk between the signal line in the second winding portion 1404 and the signal in the substrate 11 below the light-transmitting hole 13. In the above embodiment, the second winding portion 1404 is formed on the side of the third opening 1323 facing the adjacent first light-transmitting hole 1331 and the side of the third opening 1323 facing the adjacent second opening 1322. Thus, the second winding portion 1404 can expose the side of the third opening 1323 facing the second light-transmitting hole 1332 , thereby reducing the probability of crosstalk between the signal line in the second winding portion 1404 and the signal in the substrate 11 below the light-transmitting hole 13 .

[0089] In the above embodiment, if Figure 7 As shown, the mesh structure 1401 further includes a first extension portion 1405 , which is connected to the first winding portion 1402 . The first extension portion 1405 is located between the adjacent first opening 1321 and the second opening 1322 , and / or between the adjacent third opening 1323 and the second opening 1322 .

[0090] Reference Figure 6 As shown, specifically, when the distance between at least part of the first opening 1321 and the second opening 1322 in the first opening column A1 is relatively close, the second light-transmitting hole 1332 may not be set between the two to ensure the preparation yield of the isolation structure 131. At this time, a first protruding portion 1405 connected to the first winding portion 1402 between the first opening 1321 and the second opening 1322 which are relatively close is set to increase the area of ​​the mesh structure 1401, thereby improving the touch effect.

[0091] In one possible implementation, Figure 8As shown, three light-transmitting holes 133 are arranged around the first opening 1321, the touch sublayer 140 includes a mesh structure 1401, the mesh structure 1401 includes a third winding portion 1406 and a second discontinuous portion 1407, the second discontinuous portion and the third winding portion are arranged together around the first opening, the third winding portion 1406 is arranged around part of the circumference of the first opening 1321 and part of the circumference of at least one light-transmitting hole 133, and the second discontinuous portion 1407 is at least located between the first opening 1321 and one of the adjacent light-transmitting holes 133.

[0092] In the above embodiment, the mesh structure 1401 includes a third winding portion 1406 and a second discontinuous portion 1407 formed in the third winding portion 1406. The third winding portion 1406 is arranged around a portion of the first opening 1321 and a portion of the at least one light-transmitting hole 133, thereby ensuring the area of ​​the third winding portion 1406 to ensure a touch effect. The second discontinuous portion 1407 is located at least between the first opening 1321 and one of the adjacent light-transmitting holes 133. This eliminates the need for the mesh structure 1401 to be positioned between the first opening 1321 and one of the light-transmitting holes 133. This reduces the area of ​​the mesh structure 1401 surrounding the light-transmitting hole 133, thereby reducing the probability of crosstalk between the signal line within the touch sublayer 140 and the signal within the substrate 11 below the light-transmitting hole 133.

[0093] In the above embodiment, the first light emitting unit 120 is a blue light emitting unit 120 and the second light emitting unit 120 is a red light emitting unit 120 , or the first light emitting unit 120 is a red light emitting unit 120 and the second light emitting unit 120 is a blue light emitting unit 120 .

[0094] In the above embodiment, if Figure 8 As shown, the mesh structure 1401 further includes a fourth winding portion 1408 , which connects two adjacent third winding portions 1406 and the first winding portion 1402 , and surrounds a portion of the third opening 1323 in the circumferential direction.

[0095] On the one hand, the fourth winding portion 1408 can realize the electrical connection between the adjacent third winding portion 1406 and the first winding portion 1402 to realize signal transmission; on the other hand, the fourth winding portion 1408 can ensure the area of ​​the mesh structure 1401 to ensure the touch effect; in addition, the touch sublayer 140 has a certain reflective effect on light, and the part of the fourth winding portion 1408 surrounding the third opening 1323 in the circumferential direction can reduce the reflection difference around the first opening 1321, the second opening 1322 and the third opening 1323 while exposing the part of the circumferential direction of the third opening 1323. Specifically, the side of the third opening 1323 facing the light-transmitting hole 133 can be exposed to reduce the probability of crosstalk between the signal line in the second winding portion 1404 and the signal in the substrate 11 below the light-transmitting hole 133.

[0096] In the above embodiment, the fourth winding portion 1408 is formed on the side of the third opening 1323 facing the adjacent second opening 1322. This allows the second winding portion 1404 to expose the side of the third opening 1323 facing the light-transmitting hole 133, thereby reducing the probability of crosstalk between the signal line in the second winding portion 1404 and the signal in the substrate 11 below the hole area.

[0097] In the above embodiment, if Figure 3 and Figure 8 As shown, the mesh structure 1401 also includes a second extension portion 1409, which is connected to the third winding portion 1406, and the second extension portion 1409 is located between the adjacent first opening portion 1321 and the second opening portion 1322, and / or between the adjacent third opening 1323 and the second opening 1322.

[0098] Specifically, when the distance between at least part of the first opening 1321 and the second opening 1322 in the first opening column A1 is relatively close, the second light-transmitting hole 1332 may not be set between the two to ensure the preparation yield of the isolation structure 131. At this time, a second protruding portion 1409 connected to the third winding portion 1406 between the first opening 1321 and the second opening 1322 with a relatively close distance is set to increase the area of ​​the mesh structure 1401, thereby improving the touch effect.

[0099] In one possible implementation, Figure 3 As shown, the touch sub-layer 140 further includes a compensation structure 1410 . The compensation structure 1410 is spaced apart from the mesh structure 1401 . The compensation structure 1410 is disposed between partially adjacent second openings 1322 and third openings 1323 .

[0100] In the above embodiment, the touch sublayer 140 has a certain reflective effect on light, and the mesh structure 1401 is disposed around a portion of the periphery of the first opening 1321, thereby increasing the reflectivity of the periphery of the first opening 1321. By disposing the compensation structure 1410 between the second opening 1322 and the third opening 1323, i.e., around the second and third openings 1322 and 1323, the difference in reflection around the first, second, and third openings 1321, 1322, and 1323 can be reduced, thereby improving the uniformity of reflection at various locations on the display panel 1 and reducing display differences between various locations on the display panel 1, thereby improving the display quality.

[0101] In the above embodiment, the compensation structure 1410 is spaced apart from the mesh structure 1401, and no signal is present within the compensation structure 1410. Therefore, the compensation structure 1410 disposed around the opening 132 does not cause crosstalk. Furthermore, because the first light-transmitting aperture 1331 includes adjacent first and second sub-apertures 1335 and 1336, a first sub-aperture 1335 or a second sub-aperture 1336 is formed between adjacent first and second openings 1321 and 1322. The first sub-aperture 1335 and the second sub-aperture 1336 are symmetrical about an axis of symmetry parallel to the second direction y, and the sidewalls of the first and second sub-apertures 1335 and 1336 are symmetrical about the axis of symmetry parallel to the second direction y. The mesh structure 1401 can be arranged around a portion of the circumference of the first sub-hole 1335, and the mesh structure 1401 can not be arranged around the second sub-hole 1336. The above-mentioned compensation structure 1410 is arranged at the place where the side wall area of ​​the second sub-hole 1336 is larger, that is, at the first part 1333, so as to reduce the probability of crosstalk while maintaining uniformity.

[0102] In one possible implementation, Figure 3 and Figure 9 As shown, the substrate 11 includes a substrate 111, and a driving circuit layer 112 and a planarization layer 113 stacked along a side away from the substrate 111. The light-emitting layer 12 includes a first electrode 121, a light-emitting functional layer 122 and a second electrode 123 stacked along a direction away from the planarization layer 113. The first electrode 121 is connected to the driving circuit layer 112 through a via hole penetrating the planarization layer 113. The orthographic projection of the edge of the isolation structure 131 on the substrate 111 does not overlap with the orthographic projection of the via hole on the substrate 111.

[0103] In the above embodiment, the via hole is deep, and there is no organic layer between the via hole and the isolation structure layer 13, which makes the flatness at the via hole position poor. If the orthographic projection of the edge of the isolation structure 131 on the substrate 111 overlaps with the orthographic projection of the via hole on the substrate 111, the etching solution will accumulate above the via hole during the preparation process of the isolation structure 131, thereby affecting the etching effect of the isolation structure 131. Therefore, in the above embodiment of the present application, the edge of the isolation structure 131 is avoided from the via hole to ensure the patterning effect of the isolation structure 131 and improve the preparation yield. In a feasible embodiment, as Figure 3 and Figure 9 As shown, the vias include a first via 1131 and / or a second via 1132, the orthographic projection of the touch sublayer 140 on the substrate 111 at least partially overlaps with the orthographic projection of the first via 1131 on the substrate 111, and the orthographic projection of the isolation structure 131 on the substrate 111 covers the orthographic projection of the first via 1131 on the substrate 111;

[0104] like Figure 3As shown, the orthographic projection of the touch sublayer 140 on the substrate 111 does not overlap with the orthographic projection of the second via 1132 on the substrate 111 , and the orthographic projection of the isolation structure 131 on the substrate 111 does not overlap with at least part of the orthographic projection of the second via 1132 on the substrate 111 .

[0105] In the above embodiment, a touch sublayer 140 needs to be set above the first via 1131. In order to ensure the shielding effect between the signal in the touch sublayer 140 and the signal in the substrate 11, the first via 1131 needs to be covered by an isolation structure 131 set between the touch sublayer 140 and the substrate 11, so that the edge of the isolation structure 131 avoids the first via 1131, thereby achieving a balance between the shielding effect and the yield of the edge of the isolation structure 131.

[0106] In the above embodiment, the touch sub-layer 140 does not need to be disposed above the second via hole 1132 . Therefore, the isolation structure 131 may not be disposed on at least part of the second via hole 1132 facing away from the substrate 11 , thereby increasing the area of ​​the light-transmitting hole 133 and thus improving the light transmittance.

[0107] In one possible implementation, Figure 9 As shown, the isolation structure 131 includes a first isolation portion 134 and a second isolation portion 135 stacked in a direction away from the substrate 11 , and the orthographic projection of the first isolation portion 134 on the substrate 11 is located within the orthographic projection of the second isolation portion 135 on the substrate 11 .

[0108] In the above-described embodiment, the first isolating portion 134 can cooperate with the second isolating portion 135 to isolate the light-emitting functional layer 122 and the second electrode 123 of the light-emitting unit 120, thereby making different light-emitting units 120 independent of each other, thereby reducing crosstalk between adjacent light-emitting units 120 and improving the display effect. Furthermore, the independence of adjacent light-emitting units 120 allows for independent packaging, thereby improving the packaging yield. Furthermore, due to the presence of the first isolating portion 134 and the second isolating portion 135, the light-emitting functional layer 122 and the second electrode 123 of each color light-emitting unit 120 in the display panel 1 can be fabricated and then patterned in their entirety, thereby eliminating the need for a mask and reducing the manufacturing cost of the display panel 1.

[0109] In the above embodiment, the orthographic projection of the second isolation portion 135 on the substrate 11 covers the orthographic projection of the first isolation portion 134 on the substrate 11, and the orthographic projection area of ​​the second isolation portion 135 on the substrate 11 is larger than the orthographic projection area of ​​the first isolation portion 134 on the substrate 11, so that a step portion is formed between the first isolation portion 134 and the second isolation portion 135 to separate the light-emitting functional layer 122 and the second electrode 123, thereby realizing the independence of different light-emitting units 120 from each other.

[0110] In the above embodiment, the isolation structure 131 comprises a conductive material, so that the second electrode 123 can be connected to the isolation structure 131 to achieve centralized power supply to the second electrode 123 , thereby reducing the number of signal lines in the display panel 1 and lowering the manufacturing cost.

[0111] The present application also provides another display panel 1, comprising a substrate 11, a light-emitting layer 12, an isolation structure layer 13, and a touch layer 14. The light-emitting layer 12 is formed on one side of the substrate 11 and comprises a plurality of light-emitting units 120. The isolation structure layer 13 is formed on the side of the light-emitting layer 12 facing away from the substrate 11 and comprises an isolation structure 131, an opening 132, and a light-transmitting hole 133. The opening 132 and the light-transmitting hole 133 are formed by enclosing the isolation structure 131. The opening 132 is used to expose the light-emitting unit 120. The light-transmitting hole 133 is formed between at least part of adjacent openings 132. The orthographic projection of the isolation structure 131 on the substrate 11 comprises a first projection area 1311 and a second projection area 1312. The touch layer 14 comprises a touch sublayer 140. The orthographic projection of the touch sublayer 140 on the substrate 11 is located within the first projection area 1311, and the orthographic projection of the touch sublayer 140 on the substrate 11 does not overlap with the second projection area 1312.

[0112] The display panel 1 provided in the present application includes a substrate 11, a light-emitting layer 12, an isolation structure layer 13 and a touch layer 14. The light-emitting layer 12 includes a plurality of light-emitting units 120, and the light-emitting units 120 are used to emit light to realize the display function of the display panel 1. The isolation structure layer 13 is formed on the side of the light-emitting layer 12 away from the substrate 11. The isolation structure layer 13 includes an isolation structure 131, an opening 132 and a light-transmitting hole 133. The isolation structure 131 is an opaque area or an area with poor transparency. The isolation structure 131 encloses the opening 132 and the light-transmitting hole 133. The opening 132 is used to expose the light-emitting unit 120 to achieve light emission. The light-transmitting hole 133 is located between at least part of adjacent openings 132, that is, the orthographic projection of the light-transmitting hole 133 on the substrate 11 is located between the orthographic projections of at least part of the light-emitting units 120 on the substrate 11, thereby achieving light transmission in the area between adjacent light-emitting units 120 to improve the light transmittance of the display panel 1. The touch layer 14 is formed on the side of the isolation structure layer 13 facing away from the substrate 11. The touch layer 14 includes a touch sublayer 140. The signal in the touch sublayer 140 and the signal of the signal line in the substrate 11 are easily crosstalked through the light-transmitting hole 133. In the display panel 1 provided in the present application, the orthographic projection of the isolation structure 131 on the substrate 11 includes a first projection area 1311 and a second projection area 1312. The orthographic projection of the touch sublayer 140 on the substrate 11 is located in the first projection area 1311, and the orthographic projection of the touch sublayer 140 on the substrate 11 does not overlap with the second projection area 1312. That is, the touch sublayer 140 is arranged around the light-transmitting hole 133 and the opening 132 in a partial area around the light-transmitting hole 133 and the opening 132, and the partial area around the opening 132 and the light-transmitting hole 133 is not surrounded by the touch sublayer 140, thereby reducing the probability of crosstalk between the signal line in the touch sublayer 140 and the signal in the substrate 11 below the hole area, and the orthographic projection of the part surrounding the light-transmitting hole 133 and the opening 132 on the substrate 11 is located within the orthographic projection of the first projection area 1311 on the substrate 11, thereby being shielded by the first projection area 1311. As a result, the crosstalk problem in the display panel 1 provided by the present application is improved, and the performance of the display panel 1 is improved. The present application also provides a display panel 1, such as Figure 10 and Figure 11As shown, it includes a substrate 11, a light-emitting layer 12, a pixel-defining layer 15 and a touch layer 14. The light-emitting layer 12 is formed on one side of the substrate 11 and includes a plurality of light-emitting units 120; the pixel-defining layer 15 is formed on one side of the substrate 11 and includes a main body 151 and a pixel opening 152 and a light-transmitting opening 153 formed by the main body 151. The light-emitting unit 120 is exposed to the pixel opening 152, and the light-transmitting opening 153 is formed between at least part of adjacent pixel openings 152. The orthographic projection of the part of the isolation structure 131 that encloses the light-transmitting hole 133 on the substrate 11 includes a third part 1511 and a fourth part 1512; the touch layer 14 includes a touch sublayer 140, and the orthographic projection of the touch sublayer 140 on the substrate 11 is located in the third part 1511, and the orthographic projection of the touch sublayer 140 on the substrate 11 does not overlap with the fourth part 1512.

[0113] The body 151 can be made of shielding and insulating materials. The insulating material is in direct contact with the first electrodes 121 to achieve insulation between adjacent first electrodes 121. The orthographic projection of the light-transmitting opening 153 on the substrate 11 does not overlap with the orthographic projection of the first electrodes 121 on the substrate 11.

[0114] The light-transmitting openings 153 are used to allow light to pass between adjacent light-emitting units 120, thereby improving light transmittance. The touch layer 14 is formed on the side of the pixel-defining layer 15 facing away from the substrate 11. The touch layer 14 includes a touch sublayer 140. Signals within the touch sublayer 140 and signals from signal lines within the substrate 11 are susceptible to crosstalk through the light-transmitting openings 153. In the display panel 1 provided herein, the orthographic projection of the portion of the body 151 enclosing the light-transmitting openings 153 on the substrate 11 includes a third portion 1511 and a fourth portion 1512. The orthographic projection of the touch sublayer 140 on the substrate 11 is located within the third portion 1511, and the orthographic projection of the touch sublayer 140 on the substrate 11 does not overlap with the fourth portion 1512. That is, the touch sublayer 140 is disposed around the light-transmitting opening 153 and the pixel opening 152, surrounding a portion of the area around the light-transmitting opening 153 and the pixel opening 152, while a portion of the area around the light-transmitting opening 153 and the pixel opening 152 is not surrounded by the touch sublayer 140. This reduces the probability of crosstalk between the signal lines within the touch sublayer 140 and the signals within the substrate 11 below the light-transmitting opening 153. Furthermore, the orthographic projection of the portion surrounding the light-transmitting opening 153 and the pixel opening 152 on the substrate 11 is located within the third portion 1511, thereby being shielded by the third portion 1511. Consequently, the crosstalk problem within the display panel 1 provided by the present application is improved, and the performance of the display panel 1 is enhanced.

[0115] The present application also provides a display device 2, such as Figure 12 As shown, it includes any one of the display panels 1 provided in the above embodiments of the present application.

[0116] The problem of signal line interference in the display device 2 is improved, so that the performance of the display device 2 is significantly improved.

[0117] The display device 2 can be a mobile terminal such as a mobile phone or a laptop computer, or a fixed terminal such as a television or a computer monitor, or can also be a wearable device such as a watch, etc., and this application does not make any special restrictions.
