[0028] This application provides a display panel, a display device, and a method for manufacturing the display panel. The following description, in conjunction with the accompanying drawings, will illustrate various embodiments of the display panel, the display device, and the method for manufacturing the display panel.

[0029] This application provides a display panel, which may be an organic light-emitting diode (OLED) display panel.

[0030] Please refer to Figures 1 to 3 together. Figure 1 is a partial cross-sectional view of a display panel provided in an embodiment of this application; Figure 2 is a cross-sectional view of Figure 1 at point AA in one example; and Figure 3 is a cross-sectional view of Figure 1 at point BB in one example.

[0031] As shown in Figures 1 to 3, a first aspect embodiment of this application provides a display panel, which includes: a substrate 100; an isolation structure 200 disposed on one side of the substrate 100, the isolation structure 200 enclosing an isolation opening 210; a light-emitting layer 300 including light-emitting units 310 located in the isolation opening 210; an encapsulation layer 400 including a plurality of encapsulation portions 410 located on the side of the light-emitting units 310 away from the substrate 100, the encapsulation portions 410 respectively covering the light-emitting units 310; and a touch layer 500 located on the side of the encapsulation layer 400 away from the substrate 100, the touch layer 500 including touch electrodes 510 located on the side of the encapsulation layer 400 away from the substrate 100, the touch electrodes 510 including touch lines 511, wherein the orthographic projection of the encapsulation portions 410 on the substrate 100 and the orthographic projection of the touch lines 511 on the substrate 100 at least partially overlap.

[0032] According to an embodiment of this application, the display panel includes a substrate 100, an isolation structure 200, a light-emitting layer 300, an encapsulation layer 400, and a touch layer 500. The isolation structure 200 encloses an isolation opening 210, and a light-emitting unit 310 is located within the isolation opening 210, enabling the isolation structure 200 to mitigate crosstalk between different light-emitting units 310. The encapsulation portion 410 provides encapsulation protection to the light-emitting unit 310 to improve the yield of the light-emitting unit 310. The touch layer 500 is located on the encapsulation layer 400 to mitigate the impact of the touch layer 500 on the encapsulation effect of the encapsulation layer 400. The touch electrodes 510 of the touch layer 500 are used to implement the touch function of the display panel. The surface of the encapsulation portion 410 facing away from the substrate 100 is uneven, which may affect the display effect of the display panel. The orthographic projection of the encapsulation portion 410 on the substrate 100 and the orthographic projection of the touch line 511 on the substrate 100 overlap at least partially, so that the touch line 511 can cover at least part of the encapsulation portion 410, thereby improving the display effect of the display panel and enhancing the performance of the display panel.

[0033] The substrate 100 can be configured in various ways, as shown in Figure 10. The substrate 100 may include a substrate 110 and pixel circuitry disposed on the substrate 110. The substrate 100 includes a first conductive layer, a second conductive layer, and a third conductive layer. The pixel circuitry may include a transistor 120 and a capacitor. The transistor 120 includes a semiconductor, a gate, a source, and a drain. The capacitor includes a first electrode and a second electrode. The gate and the first electrode may be located on the first conductive layer, the second electrode on the second conductive layer, and the source and drain on the third conductive layer.

[0034] Optionally, as shown in Figure 10, a first insulating layer 130 is further disposed on the substrate 100, and a first electrode layer 600 is disposed on the side of the first insulating layer 130 opposite to the substrate 100. The first electrode layer 600 includes a plurality of first electrodes 610 spaced apart. Optionally, the first insulating layer 130 can be a planarization layer.

[0035] Optionally, the display panel also includes a pixel definition layer 320, which is located on the side of the first insulating layer 130 away from the substrate 100. The pixel definition layer 320 includes a pixel defining portion 321 and a pixel opening 322. The first electrode 610 is exposed through the pixel opening 322, which is used to accommodate the light-emitting unit 310.

[0036] There are various ways to arrange the relative positions of the isolation structure 200 and the pixel definition layer 320. The isolation structure 200 can be located on the side of the pixel limiting portion 321 away from the substrate 100, or the pixel limiting portion 321 can also form a clearance opening, with the isolation structure 200 located in the clearance opening. This embodiment uses the example of the isolation structure 200 being located on the side of the pixel limiting portion 321 away from the substrate 100 for illustration. Optionally, the orthographic projection of the pixel opening 322 onto the substrate 100 and the orthographic projection of the isolation opening 210 onto the substrate 100 at least partially overlap. For example, the orthographic projection of the pixel opening 322 onto the substrate 100 is located within the orthographic projection of the isolation opening 210 onto the substrate 100, so that the isolation structure 200 does not affect the light emission of the light-emitting unit 310. The light-emitting unit 310 is located within the pixel opening 322 within the isolation opening 210.

[0037] Optionally, the display panel further includes a second electrode layer, which includes a second electrode 700 located on the side of each light-emitting unit 310 facing away from the substrate 100. The first electrode 610, the second electrode 700, and the light-emitting unit 310 form a light-emitting device. One of the first electrode 610 and the second electrode 700 is an anode, and the other is a cathode. In this embodiment, the first electrode 610 is used as the anode and the second electrode 700 is used as the cathode for illustrative purposes.

[0038] Optionally, referring to Figures 1, 2, and 10, the encapsulation layer 400 includes a first encapsulation layer 401, a second encapsulation layer 402, and a third encapsulation layer 403. The first encapsulation layer 401 includes multiple encapsulation portions 410. The second and third encapsulation layers 402 and 403 can be disposed on their entire surface. The touch layer 500 can be located on the side of the third encapsulation layer 403 opposite to the second encapsulation layer 402 to improve the encapsulation effect of the encapsulation layer 400.

[0039] There are various ways to arrange the relative positions of two adjacent encapsulation portions 410. The orthographic projections of two adjacent encapsulation portions 410 on the substrate 100 can be spaced apart from each other. Alternatively, in some optional embodiments, the encapsulation portions 410 corresponding to at least two adjacent light-emitting units 310 overlap to form an overlapping portion 410a. The orthographic projections of the overlapping portion 410a on the substrate 100 and the orthographic projections of the touch line 511 on the substrate 100 at least partially overlap. Figures 2 and 3 show the location of the overlapping portion 410a with a dashed line, but the dashed line does not constitute a limitation on the structure of this application. Optionally, the overlapping portion 410a is formed by the overlap of two adjacent encapsulation portions 410, and the overlapping portion 410a includes the portions of the two adjacent encapsulation portions 410 that overlap with each other.

[0040] In these optional embodiments, at least two adjacent encapsulation portions 410 overlap to form an overlapping portion 410a. The surface of the overlapping portion 410a is more uneven, and the orthographic projection of the overlapping portion 410a onto the substrate 100 and the orthographic projection of the touch line 511 onto the substrate 100 at least partially overlap, so that the touch line 511 can cover at least part of the overlapping portion 410a, improving the display effect of the display panel. Furthermore, as shown in Figures 2 and 4, since the encapsulation portions 410 overlap each other in the overlapping portion 410a, the surface height of the overlapping portion 410a is higher. Placing the touch line 511 on the overlapping portion 410a increases the distance between the touch line 511 and other conductive layers below, improving parasitic problems between the touch line 511 and other conductive film layers. For example, it improves parasitic capacitance problems between the touch line 511 and the isolation structure 200, or between the touch line 511 and the metal traces within the substrate 100.

[0041] In some optional embodiments, as shown in FIG3, the orthographic projection of the overlapping portion 410a on the substrate 100 is located within the orthographic projection of the touch line 511 on the substrate 100, so that the touch line 511 can better cover the overlapping portion 410a and better improve the display effect of the display panel.

[0042] When the orthographic projection of the overlapping portion 410a onto the substrate 100 lies within the orthographic projection of the touch line 511 onto the substrate 100, the width W1 of the overlapping portion 410a can be 2μm to 5μm. For example, the width W1 of the overlapping portion 410a can be 2μm, 2.2μm, 3μm, 3.5μm, 4.2μm, 5μm, etc., to improve the situation where the width W1 of the overlapping portion 410a is too small, which would not be able to support the touch line 511 well and would reduce the protective effect of the upper packaging portion 410 on the lower packaging portion 410 during the manufacturing process, resulting in reduced packaging reliability. In addition, if the width W1 of the overlapping portion 410a is too large, the overlapping portion 410a will be prone to breakage, which will also affect the coverage of the overlapping portion 410a by the touch line 511. And / or, the width W2 of the touch line 511 is 3μm to 6μm, for example, the width W2 of the touch line 511 is 3μm, 3.6μm, 4.2μm, 4.5μm, 5.1μm, 6μm, etc., to improve the effect of the touch signal transmission caused by the touch line 511 being too small, and also to improve the effect of the light emission caused by the touch line 511 being too large.

[0043] The width direction of the overlapping portion 410a can be the spacing direction between two adjacent package portions 410 forming the overlapping portion 410a, that is, it can be the arrangement direction of the two light-emitting units 310 corresponding to the two adjacent package portions 410 forming the overlapping portion 410a. In the overlapping portion 410a and the touch line 511, the width direction of the overlapping portion 410a is the same as the width direction of the touch line 511.

[0044] In some alternative embodiments, as shown in FIG2, the touch line 511 includes a first touch segment 511a, the orthographic projection of the first touch segment 511a onto the substrate 100 being within the orthographic projection of the overlapping portion 410a onto the substrate 100. The first touch segment 511a is the portion of the touch line 511 that overlaps with the overlapping portion 410a, that is, the width of the first touch segment 511a is smaller than the width of the overlapping portion 410a, so that the orthographic projection of the first touch segment 511a onto the substrate 100 is within the orthographic projection of the overlapping portion 410a onto the substrate 100. This allows the overlapping portion 410a to provide better support for the first touch segment 511a, and better improves the parasitic capacitance problem between the first touch segment 511a and the metal traces on the substrate 100 side.

[0045] Optionally, the width W2 of the touch line 511 is 3μm to 6μm. For example, the width W2 of the touch line 511 can be 3μm, 3.6μm, 4.2μm, 4.5μm, 5.1μm, 6μm, etc., to improve the situation where the width W2 of the touch line 511 is too small and affects the transmission of touch signals, and also to improve the situation where the width W2 of the touch line 511 is too large and affects light emission. When the width W2 of the touch line 511 is within a suitable range, it also ensures that the orthographic projection of the first touch segment 511a on the substrate 100 is located within the orthographic projection of the overlapping portion 410a on the substrate 100.

[0046] Optionally, when the width of the first touch segment 511a is less than the width of the overlapping portion 410a, the distance from the first touch segment 511a to the isolation openings 210 located on both sides of its width direction is greater than the distance from the overlapping portion 410a to the isolation openings 210 located on both sides of itself. The distance between the first touch segment 511a and the isolation openings 210 is the minimum spacing between the orthographic projection of the first touch segment 511a on the substrate 100 and the orthographic projection of the isolation openings 210 on the substrate 100. The distance between the overlapping portion 410a and the isolation openings 210 is the minimum spacing between the orthographic projection of the overlapping portion 410a on the substrate 100 and the orthographic projection of the isolation openings 210 on the substrate 100.

[0047] In some optional embodiments, as shown in FIG2, the encapsulation portion 410 extends from the isolation opening 210 to the side of the isolation structure 200 away from the substrate 100, that is, the encapsulation portion 410 covers part of the isolation structure 200 to increase the distribution area of ​​the encapsulation portion 410 and improve the encapsulation effect.

[0048] Optionally, the overlapping portion 410a is located on the side of the isolation structure 200 away from the substrate 100, and the orthographic projection of the touch line 511 on the substrate 100 and the orthographic projection of the isolation structure 200 on the substrate 100 at least partially overlap.

[0049] In these optional embodiments, the overlapping portion 410a is located on the side of the isolation structure 200 facing away from the substrate 100, that is, two adjacent package portions 410 overlap on the isolation structure 200. Furthermore, the orthographic projection of the touch line 511 onto the substrate 100 and the orthographic projection of the isolation structure 200 onto the substrate 100 at least partially overlap. The touch line 511 being located on the isolation structure 200 can improve the influence of the touch line 511 on the light emission of the light-emitting unit 310 within the isolation opening 210. Moreover, both the touch line 511 and the overlapping portion 410a are located on the isolation structure 200, allowing the touch line 511 and the overlapping portion 410a to overlap each other.

[0050] In some optional embodiments, as shown in Figures 2 and 3, in two adjacent encapsulation portions 410, one includes a first segment 420 located on the side of the isolation structure 200 away from the substrate 100, and the other includes a second segment 430 located on the side of the isolation structure 200 away from the substrate 100. The first segment 420 includes a first main body portion 421, and the second segment 430 includes a second main body portion 431, a first sidewall 432, and a third main body portion 433. The second main body portion 431 is connected to the third main body portion 433 through the first sidewall 432. The third main body portion 433 is located on the side of the first main body portion 421 away from the substrate 100. The third main body portion 433 and the first main body portion 421 overlap to form an overlapping portion 410a. The overlapping portion 410a is the portion of the first main body portion 421 that overlaps with the third main body portion 433 and the portion of the third main body portion 433 that overlaps with the first main body portion 433.

[0051] In these alternative embodiments, the third main body portion 433 of the second segment 430 extends through the first sidewall 432 to the side of the first main body portion 421 away from the substrate 100, such that the first main body portion 421 of the first segment 420 and the third main body portion 433 of the second segment 430 overlap each other to form an overlapping portion 410a.

[0052] Optionally, as shown in Figure 4, a fourth gap Q4 is formed between the first main body portion 421 and the third main body portion 433. During the fabrication of the light-emitting unit 310 covered by the second segment 430, some light-emitting materials, electrode materials, and encapsulation materials are sequentially stacked and cover the first main body portion 421. During subsequent patterning of the light-emitting materials, electrode materials, and encapsulation materials, the light-emitting materials and electrode materials between the third main body portion 433 and the first main body portion 421 are removed to form the aforementioned fourth gap Q4.

[0053] Optionally, the fourth gap Q4 is filled with an organic filler. When the second encapsulation layer 402 is fabricated after the first encapsulation layer 401 is completed, some material from the second encapsulation layer 402 overflows into the fourth gap Q4 to form an organic filler. The organic filler provides support to the third main body 433, ensuring the positional stability between the first main body 421 and the third main body 433, and also improving the yield of the third main body 433.

[0054] Optionally, the thickness of the organic filler portion is less than the thickness of the first main body portion 421 or the third main body portion 433. A smaller thickness of the organic filler portion, meaning a smaller distance between the first main body portion 421 and the third main body portion 433, ensures sealing and stability of the relative positions between the first main body portion 421 and the third main body portion 433.

[0055] In some optional embodiments, when the encapsulation portion 410 includes the first main body portion 421, the second main body portion 431, the first sidewall 432, and the third main body portion 433 described above, a first gap Q1 is formed between the first main body portion 421 and the first sidewall 432. The orthographic projection of the first gap Q1 onto the substrate 100 and the orthographic projection of the touch line 511 onto the substrate 100 at least partially overlap. Residual material that may affect the display effect may be present in the first gap Q1 during the manufacturing process. Covering the first gap Q1 with the touch line 511 can improve the display effect. For example, as shown in FIG3, the third main body portion 433 has a redundant unit 710 on the side facing the isolation structure 200. At least a portion of the redundant unit 710 fills the first gap Q1. The redundant unit 710 is formed from the aforementioned residual material, and the surface of the redundant unit 710 may be uneven.

[0056] Optionally, the material of the redundant unit 710 is the same as that of the second electrode 700. The uneven surface of the redundant unit 710 may reflect light, causing a display difference in the first gap Q1. In the embodiments of this application, the orthographic projection of the first gap Q1 onto the substrate 100 and the orthographic projection of the touch line 511 onto the substrate 100 at least partially overlap, so that the touch line 511 can cover the first gap Q1, improving the display difference at the location of the first gap Q1.

[0057] Optionally, the orthographic projection of the first gap Q1 onto the substrate 100 is located within the orthographic projection of the touch line 511 onto the substrate 100, so that the touch line 511 can better cover the first gap Q1.

[0058] In some alternative embodiments, the side of the third body portion 433 opposite to the first sidewall 432 is projected onto the substrate 100 in the orthographic projection of the touch line 511 onto the substrate 100.

[0059] In these optional embodiments, there is a height difference between the side of the third main body 433 away from the first sidewall 432 and the first main body 421, which may cause unevenness of the film surface and affect the display effect. The orthographic projection of the side of the third main body 433 away from the first sidewall 432 on the substrate 100 is located within the orthographic projection of the touch line 511 on the substrate 100, so that the touch line 511 can cover the side of the third main body 433 away from the first sidewall 432, which can improve the impact of the height difference on the display effect, such as improving the display uniformity problem under screen-off display.

[0060] Optionally, the orthographic projection of the third main body portion 433 onto the substrate 100 lies within the orthographic projection of the touch line 511 onto the substrate 100. During the manufacturing process of the display panel, due to the presence of the third main body portion 433, some material covered by the third main body portion 433 may remain between the third main body portion 433 and the first main body portion 421, resulting in a difference in reflectivity in the area where the third main body portion 433 is located. In this embodiment, the third main body portion 433 is covered by the touch line 511, allowing the touch line 511 to cover more of the encapsulation portion 410 and any remaining material, thus improving the display effect.

[0061] Optionally, the orthographic projection of the first sidewall 432 onto the substrate 100 lies within the orthographic projection of the touch line 511 onto the substrate 100. During the manufacturing process of the display panel, due to the presence of the first sidewall 432, some material covered by the first sidewall 432 may remain between the first sidewall 432 and the isolation structure 200 (such as the redundant unit 710 mentioned above), resulting in a difference in reflectivity in the area where the first sidewall 432 is located. In this embodiment, the first sidewall 432 is covered by the touch line 511, allowing the touch line 511 to cover more of the encapsulation portion 410 and residual material, thereby improving the display effect.

[0062] The side of the first main body portion 421 facing the second main body portion 431 is projected onto the substrate 100 within the projection of the touch line 511 onto the substrate 100. This allows the touch line 511 to cover more of the encapsulation portion 410 and to better cover the aforementioned redundant unit 710, thereby improving the display effect.

[0063] There are various ways to arrange the multiple light-emitting units 310, as shown in Figures 1 and 5. In some optional embodiments, the multiple light-emitting units 310 are arranged in rows and columns along the first direction Y and the second direction X, where the first direction Y is the column direction and the second direction X is the row direction; two adjacent encapsulation parts 410 located in the same row along the second direction X overlap each other to form an overlapping part 410a.

[0064] In these alternative embodiments, two adjacent encapsulation portions 410 in the same row overlap each other to form an overlapping portion 410a, thereby improving the encapsulation effect of the encapsulation layer 400.

[0065] Optionally, two adjacent package portions 410 located in the same column along the first direction Y are spaced apart in their orthographic projections on the substrate 100, in order to simplify the structure of the package portion 410 and avoid the package portion 410 located above the isolation structure 200 having an excessively long extension length in the first direction Y, which would cause the overlapping portion 410a to be prone to breakage.

[0066] Optionally, as shown in Figure 10, a connection via 131 is provided through the first insulating layer 130, and the first electrode 610 is electrically connected to the transistor 120 via the connection via 131. When multiple light-emitting units 310 are arranged in rows and columns, the distance between two adjacent light-emitting units 310 in the row direction is usually closer, and the distance between two adjacent light-emitting units 310 in the column direction is farther, so that structures such as the connection via 131 can be provided between two adjacent light-emitting units 310 in the column direction. Therefore, by having two adjacent package portions 410 in the same row overlap each other, two package portions 410 that are closer can overlap each other to form an overlapping portion 410a, two adjacent package portions 410 in the same column are spaced apart, and two package portions 410 that are farther apart are spaced apart in the orthographic projection of the substrate 100, which can improve the packaging reliability of the package portion 410 and prevent the risk of breakage of the package portion 410 located above the isolation structure 200.

[0067] Optionally, the plurality of light-emitting units 310 includes a first light-emitting unit 311, a second light-emitting unit 312, and a third light-emitting unit 313. The first light-emitting unit 311, the second light-emitting unit 312, and the third light-emitting unit 313 are used to emit light of different colors. The first light-emitting unit 311 can emit red light, the second light-emitting unit 312 can emit blue light, and the third light-emitting unit 313 can emit green light. In other embodiments, the first light-emitting unit 311 can also emit blue or green light, the second light-emitting unit 312 can emit red or green light, and the third light-emitting unit 313 can emit red or blue light.

[0068] In some optional embodiments, as shown in Figures 5 and 6, a plurality of first light-emitting units 311 are arranged sequentially along the first direction Y to form a first pixel column L1, and a plurality of second light-emitting units 312 are arranged sequentially along the first direction Y to form a second pixel column L2. The first pixel column L1 and the second pixel column L2 are arranged along the second direction X. The encapsulation portion 410 includes a first encapsulation portion 411 covering the first light-emitting units 311 and a second encapsulation portion 412 covering the second light-emitting units 312. The first encapsulation portions 411 and the second encapsulation portions 412 adjacent to each other along the second direction X overlap to form an overlapping portion 410a.

[0069] In these optional embodiments, a plurality of first light-emitting units 311 are sequentially distributed along the first direction Y, and a plurality of second light-emitting units 312 are sequentially distributed along the first direction Y, which simplifies the pixel arrangement structure. The distance between adjacent first encapsulation portions 411 and second encapsulation portions 412 along the second direction X is relatively small, and the overlap between the two to form an overlapping portion 410a can improve the encapsulation reliability of the encapsulation portion 410.

[0070] Optionally, two adjacent first encapsulation portions 411 along the first direction Y are spaced apart in their orthographic projections onto the substrate 100. The distance between the first encapsulation portions 411 corresponding to two adjacent first light-emitting units 311 within the first pixel column L1 is relatively large. Therefore, by arranging two adjacent first encapsulation portions 411 along the first direction Y in their orthographic projections onto the substrate 100 at intervals, the encapsulation reliability of the encapsulation portion 410 can be improved, and the structure of the encapsulation portion 410 can be simplified.

[0071] And / or, two adjacent second encapsulation portions 412 along the first direction Y are spaced apart in their orthographic projections on the substrate 100. The distance between the second encapsulation portions 412 corresponding to two adjacent second light-emitting units 312 in the second pixel column L2 is relatively large. Therefore, by arranging two adjacent second encapsulation portions 412 along the first direction Y in their orthographic projections on the substrate 100 at intervals, the encapsulation reliability of the encapsulation portion 410 can be improved and the structure of the encapsulation portion 410 can be simplified.

[0072] Optionally, as described above, the plurality of light-emitting units 310 may also include a third light-emitting unit 313. The plurality of third light-emitting units 313 are arranged sequentially along the first direction Y to form a third pixel column L3. The first pixel column L1, the second pixel column L2 and the third pixel column L3 are arranged alternately along the second direction X. The encapsulation portion 410 may also include a third encapsulation portion 413 covering the third light-emitting unit 313. The second encapsulation portion 412 and the third encapsulation portion 413 adjacent along the second direction X overlap each other to form an overlapping portion 410a, and / or the first encapsulation portion 411 and the third encapsulation portion 413 adjacent along the second direction X overlap each other to form an overlapping portion 410a.

[0073] In these alternative embodiments, the distance between the third encapsulation portion 413 and the first encapsulation portion 411 or the second encapsulation portion 412 adjacent to it along the second direction X is relatively close. Therefore, the second encapsulation portion 412 and the third encapsulation portion 413 adjacent to each other along the second direction X can overlap to form an overlapping portion 410a, and / or the first encapsulation portion 411 and the third encapsulation portion 413 adjacent to each other along the second direction X can overlap to form an overlapping portion 410a, which can improve the encapsulation reliability of the encapsulation portion 410 and simplify the structure of the encapsulation portion 410.

[0074] Optionally, two adjacent third encapsulation portions 413 along the first direction Y are spaced apart in their orthographic projections onto the substrate 100. The distance between the third encapsulation portions 413 corresponding to two adjacent third light-emitting units 313 within the third pixel column L3 is relatively large. Therefore, by arranging two adjacent third encapsulation portions 413 along the first direction Y in their orthographic projections onto the substrate 100 at intervals, the encapsulation reliability of the encapsulation portion 410 can be improved, and the structure of the encapsulation portion 410 can be simplified.

[0075] In some alternative embodiments, as shown in FIG1, the first light-emitting unit 311 and the second light-emitting unit 312 are arranged alternately along the first direction Y, and the first encapsulation portion 411 and the second encapsulation portion 412 adjacent along the first direction Y are spaced apart in their orthogonal projections on the substrate 100. The first light-emitting unit 311 and the third light-emitting unit 313 are arranged alternately along the second direction X, and the first encapsulation portion 411 and the third encapsulation portion 413 adjacent along the second direction X form an overlapping portion 410a. And / or, the second light-emitting unit 312 and the third light-emitting unit 313 are arranged alternately along the second direction X, and the second encapsulation portion 412 and the third encapsulation portion 413 adjacent along the second direction X form an overlapping portion 410a.

[0076] In these optional embodiments, the first light-emitting unit 311 and the second light-emitting unit 312 are alternately arranged along the first direction Y to form the same pixel column. Therefore, the distance between the first encapsulation portion 411 corresponding to the first light-emitting unit 311 and the second encapsulation portion 412 corresponding to the second light-emitting unit 312 is relatively large. In addition, the first encapsulation portions 411 and 412 adjacent along the first direction Y are spaced apart in their orthogonal projections on the substrate 100, which simplifies the structure of the encapsulation portion 410. The first light-emitting unit 311 and the third light-emitting unit 313 are alternately arranged along the second direction X to form the same pixel row. Therefore, the distance between the first encapsulation portion 411 corresponding to the first light-emitting unit 311 and the third encapsulation portion 413 corresponding to the third light-emitting unit 313 is relatively small. In addition, the first encapsulation portions 411 and 413 adjacent along the second direction X form an overlapping portion 410a, which simplifies the structure of the encapsulation portion 410. Similarly, the second light-emitting unit 312 and the third light-emitting unit 313 are arranged alternately along the second direction X to form the same pixel row. Therefore, the second encapsulation part 412 corresponding to the second light-emitting unit 312 and the third encapsulation part 413 corresponding to the third light-emitting unit 313 are close to each other. In addition, the second encapsulation part 412 and the third encapsulation part 413 adjacent along the second direction X form an overlapping part 410a, which can improve the encapsulation reliability of the encapsulation part 410 and simplify the structure of the encapsulation part 410.

[0077] In some alternative embodiments, as shown in FIG8, the third light-emitting unit 313 is located within a virtual quadrilateral S1, and two first light-emitting units 311 and two second light-emitting units 312 are alternately distributed at the apex corners of the virtual quadrilateral S1; wherein, the first encapsulation portion 411 and the third encapsulation portion 413 adjacent to each other along the diagonal extension direction of the virtual quadrilateral S1 overlap to form an overlapping portion 410a, and / or, the second encapsulation portion 412 and the third encapsulation portion 413 adjacent to each other along the diagonal extension direction of the virtual quadrilateral S1 overlap to form an overlapping portion 410a.

[0078] In these optional embodiments, the third light-emitting unit 313 is located within the virtual quadrilateral S1, and the first light-emitting unit 311 and the second light-emitting unit 312 are located at the apex of the virtual quadrilateral S1. The distance between the first light-emitting unit 311 and the third light-emitting unit 313 is relatively small. Furthermore, the first encapsulation portion 411 and the third encapsulation portion 413, which are adjacent along the diagonal extension direction of the virtual quadrilateral S1, overlap to form an overlapping portion 410a, which simplifies the structure of the encapsulation portion 410. Similarly, the distance between the second light-emitting unit 312 and the third light-emitting unit 313 is relatively small, and the second encapsulation portion 412 and the third encapsulation portion 413, which are adjacent along the diagonal extension direction of the virtual quadrilateral S1, overlap to form an overlapping portion 410a, which improves the encapsulation reliability of the encapsulation portion 410 and simplifies the structure of the encapsulation portion 410.

[0079] Optionally, the first package portion 411 and the second package portion 412 are spaced apart in the orthographic projection of the substrate 100. Optionally, two adjacent third package portions 413 are spaced apart in the orthographic projection of the substrate 100.

[0080] In some optional embodiments, as shown in Figures 8 to 9, the touch line 511 includes a first trace portion 512, which is located between adjacent first light-emitting units 311 and third light-emitting units 313, and / or, the first trace portion 512 is located between adjacent second light-emitting units 312 and third light-emitting units 313, wherein the orthographic projection of the overlapping portion 410a on the substrate 100 and the orthographic projection of the first trace portion 512 on the substrate 100 at least partially overlap.

[0081] In these optional embodiments, the first wiring portion 512 is located between adjacent first light-emitting units 311 and third light-emitting units 313, that is, the orthographic projection of the first wiring portion 512 on the substrate 100 is located between the orthographic projections of the first light-emitting unit 311 and the third light-emitting unit 313 on the substrate 100. Therefore, the overlapping portion 410a formed by the overlapping of the first encapsulation portion 411 and the third encapsulation portion 413 can overlap with the first wiring portion 512. And / or, the first wiring portion 512 is located between adjacent second light-emitting units 312 and third light-emitting units 313, that is, the orthographic projection of the first wiring portion 512 on the substrate 100 is located between the orthographic projections of the second light-emitting unit 312 and the third light-emitting unit 313 on the substrate 100. Therefore, the overlapping portion 410a formed by the overlapping of the second encapsulation portion 412 and the third encapsulation portion 413 can overlap with the first wiring portion 512.

[0082] In some optional embodiments, the touch line 511 further includes a second wiring portion 513, which is located between adjacent second light-emitting units 312 and first light-emitting units 311, and at least one second wiring portion 513 encloses and forms a hollow area K.

[0083] In these optional embodiments, when the first light-emitting unit 311, the second light-emitting unit 312, and the third light-emitting unit 313 are arranged in the above-described pixel arrangement structure, the gap between adjacent first light-emitting units 311 and second light-emitting units 312 along the first direction Y and / or the second direction X is relatively large. At least one second wiring portion 513 encloses the gap to form a hollow area K. On the one hand, this makes the width of the touch line 511 in this area similar to that of the touch line 511 in other areas, improving the uniformity of the wiring of the touch line 511. On the other hand, it makes the distance from the second wiring portion 513 to the isolation opening 210 or the pixel opening 322 similar to that of the touch line 511 in other areas, making the influence of the touch line 511 in different areas on the light emission of the light-emitting unit 310 consistent, thus improving the uniformity of the display.

[0084] Optionally, the first light-emitting unit 311 and the second light-emitting unit 312 are alternately arranged along the first direction Y to form a fourth pixel column, and the first light-emitting unit 311 and the second light-emitting unit 312 are alternately arranged along the second direction X to form a first pixel row. The second wiring portion 513 is correspondingly located between adjacent first light-emitting units 311 and second light-emitting units 312 along the first direction Y and / or the second direction X. That is, the second wiring portion 513 is correspondingly located between adjacent first light-emitting units 311 and second light-emitting units 312 within the fourth pixel column, or the second wiring portion 513 is correspondingly located between adjacent first light-emitting units 311 and second light-emitting units 312 within the first pixel row.

[0085] Optionally, the second wiring section 513 includes a first sub-wiring 513a and a second sub-wiring 513b. The first sub-wiring 513a is located between the first light-emitting unit 311 and the second light-emitting unit 312 adjacent along the first direction Y, and the second sub-wiring 513b is located between the first light-emitting unit 311 and the second light-emitting unit 312 adjacent along the second direction X.

[0086] Optionally, the hollow area K can be formed by the second sub-line 513b, and / or by the first sub-line 513a. Optionally, since the spacing between adjacent first light-emitting units 311 and second light-emitting units 312 along the second direction X is large, any second sub-line 513b can form the hollow area K. Optionally, a portion of the first sub-line 513a can form the hollow area K. Since there are two types of gaps between adjacent first light-emitting units 311 and second light-emitting units 312 along the first direction Y, the first sub-line 513a within the larger gap can form the hollow area K.

[0087] Optionally, the cutout region K includes a first cutout portion K1 formed by at least one first sub-line 513a and a second cutout portion K2 formed by at least one second sub-line 513b. The projected area of ​​the first cutout portion K1 on the substrate 100 is smaller than the projected area of ​​the second cutout portion K2 on the substrate 100. Referring to the above, when both the first sub-line 513a and the second sub-line 513b form the cutout region K, the area of ​​the first cutout portion K1 formed by the first sub-line 513a is smaller to adapt to the pixel arrangement structure.

[0088] In some optional embodiments, as shown in FIG6, the touch layer 500 includes a first touch layer 520 and a second touch layer 530, with an insulating dielectric layer 540 disposed between the first touch layer 520 and the second touch layer 530. The touch electrode 510 includes a first touch segment 521 located in the first touch layer 520 and a second touch segment 531 located in the second touch layer 530. The insulating dielectric layer 540 is provided with a dielectric via 541. The first touch segment 521 and the second touch segment 531 are electrically connected through the dielectric via 541 and the overlapping portion 410a are spaced apart in the orthographic projection of the dielectric via 541 onto the substrate 100. In these optional embodiments, the dielectric via 541 and the overlapping portion 410a are spaced apart to further improve the display effect.

[0089] In the touch layer 500, the via 541 has a relatively large aperture. To mitigate the impact of the metal material within the via 541 on the light emission of the light-emitting unit 310, the via 541 is positioned on a wider isolation structure 200, ensuring that the orthographic projection of the via 541 onto the substrate 100 lies within the orthographic projection of the isolation structure 200 onto the substrate 100. To ensure that adjacent package portions 410 typically overlap on a narrower isolation structure 200 to form an overlapping portion 410a, in this embodiment, the overlapping portion 410a and the via 541 are spaced apart, resulting in a more rational distribution of the overlapping portion 410a and the via 541.

[0090] Optionally, at least one dielectric via 541 and at least one overlapping portion 410a are arranged around different sides of the same isolation opening 210 in the orthographic projection of the substrate 100, so that the dielectric via 541 and the overlapping portion 410a are spaced apart from each other.

[0091] Optionally, as shown in Figures 2, 6 and 7, the isolation structure 200 includes a first isolation segment 220 and a second isolation segment 230. The orthographic projection of the overlapping portion 410a onto the substrate 100 is located within the orthographic projection of the first isolation segment 220 onto the substrate 100. The orthographic projection of the dielectric via 541 onto the substrate 100 is located within the orthographic projection of the second isolation segment 230 onto the substrate 100. The width W3 of the first isolation segment 220 is smaller than the width W4 of the second isolation segment 230.

[0092] In these alternative embodiments, the width W3 of the first isolation segment 220 is small, and the width W4 of the second isolation segment 230 is large. Adjacent encapsulation portions 410 are prone to forming overlapping portions 410a on the first isolation segment 220. The dielectric via 541 is disposed on the second isolation segment 230, which can improve the influence of the dielectric via 541 on the light emission effect of the light-emitting unit 310.

[0093] Optionally, at least two adjacent package portions 410 are spaced apart on the side of the second isolation section 230 away from the substrate 100 to simplify the structure of the package portion 410.

[0094] In some optional embodiments, as shown in FIG2, the ratio of the width W1 of the overlapping portion 410a to the width W2 of the touch line 511 is 1.5 to 0.5. For example, the ratio of the width W1 of the overlapping portion 410a to the width W2 of the touch line 511 is 1.5, 1.2, 1.0, 7, 0.5, etc. When the width ratio of the overlapping portion 410a and the touch line 511 is within a suitable range, it can both mitigate the problem of the overlapping portion 410a being too wide and extending onto the light-emitting unit 310, thus affecting the light-emitting effect of the light-emitting unit 310, and also mitigate the problem of the touch line 511 being too wide, thus affecting the light-emitting effect of the light-emitting unit 310. It can also mitigate the problem of the overlapping portion 410a being too narrow, thus affecting its support for the touch line 511, and the touch line 511 being too narrow, thus affecting the transmission of touch signals.

[0095] Optionally, the orthographic projection of the overlapping portion 410a onto the substrate 100 lies within the orthographic projection of the touch line 511 onto the substrate 100, and the width of the overlapping portion 410a is 2μm to 5μm; for example, the width W1 of the overlapping portion 410a is 2μm, 2.2μm, 3μm, 3.5μm, 4.2μm, 5μm, etc., to improve the situation where the width W1 of the overlapping portion 410a is too small and cannot support the touch line 511 well, and also to improve the situation where the width W1 of the overlapping portion 410a is too large and affects the coverage of the touch line 511. And / or, the width W2 of the touch line 511 is 3μm to 6μm, for example, the width W2 of the touch line 511 is 3μm, 3.6μm, 4.2μm, 4.5μm, 5.1μm, 6μm, etc., to improve the effect of the touch signal transmission caused by the touch line 511 being too small, and also to improve the effect of the light emission caused by the touch line 511 being too large.

[0096] In some alternative embodiments, as described above and shown in FIG10, the display panel further includes a transistor 120, a first insulating layer 130, and a first electrode 610, wherein the orthographic projection of the connecting via 131 on the substrate 100 and the overlapping portion 410a on the orthographic projection of the substrate 100 are spaced apart.

[0097] In these alternative embodiments, due to the presence of the connecting via 131, some pixel defining portions 321 and / or isolation structures 200 are recessed toward the substrate 100, resulting in surface unevenness. The surface of the overlapping portion 410a facing away from the substrate 100 is also uneven. By spaced the connecting via 131 and the overlapping portion 410a, the accumulation of unevenness on the overlapping portion 410a can be mitigated, thus reducing its impact on the display effect of the display panel.

[0098] Optionally, the projection of the connecting via 131 onto the substrate 100 and the projection of the encapsulation portion 410 onto the substrate 100 are spaced apart. This allows the recess formed by the connecting via 131 on the isolation structure 200 and the encapsulation portion 410 to be spaced apart, enabling the encapsulation portion 410 to extend along a relatively flat surface and improving the encapsulation effect.

[0099] In some alternative embodiments, as shown in Figures 11 and 12, at least two adjacent encapsulation portions 410 are continuously formed in a continuous region 440 on the side of the isolation structure 200 facing away from the substrate 100. This simplifies the structure of the encapsulation portion 410, improves the yield of the encapsulation portion 410, and thus improves the performance of the display panel.

[0100] Optionally, the touch line 511 includes a plurality of second touch segments 511b distributed in its extending direction, at least one of the second touch segments 511b having its orthographic projection on the substrate 100 located within the orthographic projection of the continuous region 440 on the substrate 100. Optionally, the film height of the continuous region 440 is higher than the height of other areas of the first encapsulation layer 401. By placing the second touch segments 511b on the continuous region 440, the distance between the second touch segments 511b and other underlying conductive layers can be increased, improving the parasitic problem between the second touch segments 511b and other conductive film layers. Furthermore, the continuous region 440 is formed on the side of the isolation structure 200 facing away from the substrate 100, so at least a portion of the touch line 511 located on the isolation structure 200 can also be conveniently placed on the continuous region 440. The second touch segments 511b are the portions of the touch line 511 that overlap with the continuous region 440.

[0101] Optionally, adjacent light-emitting units 310 with the same emission color can form a continuous region 440 with corresponding encapsulation portions 410. Multiple light-emitting units 310 of the same color can be fabricated in the same process step, and the encapsulation portions 410 corresponding to multiple light-emitting units 310 of the same color can also be fabricated in the same process step. When fabricating the encapsulation portions 410 corresponding to multiple light-emitting units 310 of the same color, by retaining some material, at least two encapsulation portions 410 corresponding to light-emitting units 310 with the same emission color can be connected to each other. Under the premise of simplifying the process steps, the structure of the first encapsulation layer 401 can also be simplified, the yield of the first encapsulation layer 401 can be improved, and thus the performance of the display panel can be improved.

[0102] When the encapsulation portion 410 forms a continuous region 440 on the side of the isolation structure 200 away from the substrate 100, it can be considered that the two encapsulation portions 410 forming the continuous region 440 are integrally formed, and there is no gap between the two encapsulation portions 410, nor do they overlap each other.

[0103] There are various ways to set up the isolation structure 200. In some optional embodiments, the isolation structure 200 includes a first sub-layer 201 and a second sub-layer 202 stacked in a direction away from the substrate 100, wherein the orthographic projection of the first sub-layer 201 onto the substrate 100 is located within the orthographic projection of the second sub-layer 202 onto the substrate 100.

[0104] In these optional embodiments, the second sublayer 202 is located on the side of the first sublayer 201 away from the substrate 100, and the size of the second sublayer 202 is larger than the size of the first sublayer 201, so that a concave shape can be formed under the second sublayer 202. When fabricating the light-emitting unit 310, the light-emitting material can be broken at the edge of the second sublayer 202 to form independent light-emitting units 310, eliminating the need to use a precision vapor deposition mask to fabricate the light-emitting unit 310, which simplifies the fabrication process of the display panel.

[0105] Optionally, the isolation structure 200 further includes a third sublayer 203 located on the side of the first sublayer 201 facing the substrate 100, wherein the orthographic projection of the first sublayer 201 onto the substrate 100 lies within the orthographic projection of the third sublayer 203 onto the substrate 100. By providing the third sublayer 203, during the fabrication of the isolation structure 200, when the first sublayer 201 is side-etched such that its size is smaller than that of the second sublayer 202, the third sublayer 203 can provide protection to the film layer of the isolation structure 200 facing the substrate 100.

[0106] Optionally, the isolation structure 200 is made of a conductive material, and the second electrode 700 is electrically connected to the isolation structure 200, allowing multiple second electrodes 700 to be interconnected as surface electrodes via the isolation structure 200. Optionally, the first sub-layer 201 is made of a conductive material, and the second electrode 700 is electrically connected to the first sub-layer 201. Optionally, the second electrode 700 and the third sub-layer 203 are electrically connected, which can increase the distribution area of ​​the conductive material and reduce the voltage drop of the second electrode 700.

During the fabrication of the light-emitting unit 310, etching material can penetrate between the continuous region 440 and the isolation structure 200, thereby removing redundant light-emitting material between the continuous region 440 and the isolation structure 200, thus forming a gap between the continuous region 440 and the isolation structure 200. Optionally, the isolation structure 200 includes a top surface facing away from the substrate 100, and a gap exists between the continuous region 440 and the top surface.

[0108] Optionally, the orthographic projection of the continuous region 440 onto the substrate 100 lies within the orthographic projection of the isolation structure 200 onto the substrate 100. This allows the packaging portion 410 to cover the isolation structure 200 and provide packaging protection to the isolation structure 200.

[0109] In some optional embodiments, as shown in FIG1, the touch layer 500 further includes a notch 550, with two adjacent touch lines 511 spaced apart by the notch 550, and at least one notch 550 is projected onto the substrate 100 outside the projected onto the overlapping portion 410a of the substrate 100. This allows more touch lines 511 to overlap with the overlapping portion 410a.

[0110] In some optional embodiments, as shown in FIG13, the touch electrode 510 includes a first touch electrode 501 extending along a first direction Y and arranged along a second direction X, and a second touch electrode 502 extending along the second direction X and arranged along the first direction Y.

The orthographic projection of the second gap Q2 on the substrate 100 is located outside the orthographic projection of the overlapping portion 410a on the substrate 100. The second gap Q2 and the overlapping portion 410a are spaced apart so that more touch lines 511 can overlap with the overlapping portion 410a.

[0111] Optionally, as shown in Figure 14, the touch layer 500 further includes a dummy electrode 503, with a third gap Q3 between the dummy electrode 503 and the touch electrode 510. The orthographic projection of the third gap Q3 onto the substrate 100 is outside the orthographic projection of the overlapping portion 410a onto the substrate 100. This allows more touch lines 511 to overlap with the overlapping portion 410a.
