The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0028] It should be understood that when describing the structure of a component, when a layer or a region is referred to as being "on" or "over" another layer or another region, it may mean that it is directly on the other layer or another region, or that other layers or regions are included between it and the other layer or another region.

The embodiments of the display panel, the display device, and the method for manufacturing a display panel are described below in conjunction with the accompanying drawings.

[0030] An embodiment of the present application provides a display panel, which may be an organic light emitting diode (OLED) display panel.

[0031] Please also read Figures 1 to 3 , Figure 1 is a partial cross-sectional view of a display panel provided in an embodiment of the present application; Figure 2 yes Figure 1 A cross-sectional view at AA in one example; Figure 3 yes Figure 1 A cross-sectional view at BB in one example.

[0032] like Figure 1 and Figure 2 In a first aspect, an embodiment of the present application provides a display panel, which includes: a substrate 100; an isolation structure 200, which is located on one side of the substrate 100 and encloses an isolation opening 240; a light-emitting layer, which is located on one side of the substrate 100 and includes light-emitting units 330 located in the isolation opening 240; a first encapsulation layer 400, which includes an encapsulation portion 401 for encapsulating each light-emitting unit 330, wherein the encapsulation portions 401 corresponding to at least two adjacent light-emitting units 330 are interconnected on a side of the isolation structure 200 that is away from the substrate 100.

[0033] According to the display panel of the embodiment of the present application, the display panel includes a substrate 100, an isolation structure 200, a light-emitting layer and a first encapsulation layer 400. The isolation structure 200 encloses an isolation opening 240, and the light-emitting unit 330 is located in the isolation opening 240, so that the isolation structure 200 can improve the problem of easy crosstalk between different light-emitting units 330. The encapsulation part 401 is used to provide encapsulation protection to the light-emitting unit 330 to improve the yield of the light-emitting unit 330. The encapsulation parts 401 corresponding to at least two adjacent light-emitting units 330 are interconnected on the isolation structure 200, which can simplify the structure of the first encapsulation layer 400, improve the yield of the first encapsulation layer 400, and thus improve the performance of the display panel.

[0034] Optionally, the display panel further includes a pixel definition layer 300, the pixel definition layer 300 includes a pixel defining portion 310 and a pixel opening 320 formed by the pixel defining portion 310, the pixel opening 320 is connected to the isolation opening 240, and the light emitting unit 330 can be located in the pixel opening 320 in the isolation opening 240, so that the light emitting unit 330 can emit light through the isolation opening 240. Optionally, the isolation structure 200 can be located on the side of the pixel defining portion 310 away from the substrate 100, or a clearance opening is provided on the pixel defining portion 310, and the isolation structure 200 is located in the clearance opening.

[0035] There are many ways to set up the isolation structure 200. In some optional embodiments, the isolation structure 200 includes a first layer 210 and a second layer 220 stacked in a direction away from the substrate 100, and the orthographic projection of the first layer 210 on the substrate 100 is located within the orthographic projection of the second layer 220 on the substrate 100.

[0036] In these optional embodiments, the second layer 220 is located on the side of the first layer 210 away from the substrate 100, and the size of the second layer 220 is larger than that of the first layer 210, so that a concave can be formed under the second layer 220. When preparing the light-emitting unit 330, the light-emitting material can be broken at the edge of the second layer 220 to form independent light-emitting units 330. There is no need to use a precision evaporation mask plate to prepare the light-emitting unit 330, which can simplify the preparation process of the display panel.

[0037] Optionally, when the isolation structure 200 includes the first layer 210 and the second layer 220, during the preparation of the display panel, a light-emitting material layer and an encapsulation material layer may be disposed on the entire surface of the isolation structure 200, and a portion of the light-emitting material layer falls into the isolation opening 240 to form a light-emitting unit 330, and then the light-emitting material layer and the encapsulation material layer in the non-target area are removed to form the light-emitting unit 330 located in the isolation opening 240 and the encapsulation portion 401 located in the target area. In the embodiment of the present application, since the encapsulation portions 401 corresponding to at least two adjacent light-emitting units 330 are interconnected on the isolation structure 200, when the light-emitting material layer and the encapsulation material layer in the non-target area are removed, the area of ​​the encapsulation material layer to be removed can be reduced, the preparation process can be simplified, and the preparation efficiency and yield can be improved.

[0038] Optionally, the display panel further includes a first electrode 610 located on the side of the light emitting unit 330 facing the substrate 100 and a second electrode 700 located on the side of the light emitting unit 330 facing away from the substrate 100, and the first electrode 610 and the second electrode 700 are used to drive the light emitting unit 330 to emit light. One of the first electrode 610 and the second electrode 700 is an anode, and the other is a cathode. The embodiment of the present application is described by taking the first electrode 610 as an anode and the second electrode 700 as a cathode.

[0039] Optionally, the isolation structure 200 further includes a third layer 230 located on the side of the first layer 210 facing the substrate 100, and the orthographic projection of the first layer 210 on the substrate 100 is located within the orthographic projection of the third layer 230 on the substrate 100. By providing the third layer 230, during the preparation process of the isolation structure 200, when the first layer 210 is side-engraved so that the size of the first layer 210 is smaller than the second layer 220, the third layer 230 can provide protection for the film layer on the side of the isolation structure 200 facing the substrate 100.

[0040] Optionally, the material of the isolation structure 200 includes a conductive material, and the second electrode 700 is electrically connected to the isolation structure 200, so that the plurality of second electrodes 700 can be interconnected as a surface electrode through the isolation structure 200. Optionally, the material of the first layer 210 includes a conductive material, and the second electrode 700 is electrically connected to the first layer 210. Optionally, the second electrode 700 and the third layer 230 are electrically connected to each other, which can increase the distribution area of ​​the conductive material and reduce the voltage drop of the second electrode 700.

[0041] In some optional embodiments, such as Figure 2 and Figure 4 As shown, the encapsulation parts 401 corresponding to at least two adjacent light-emitting units 330 of the same color are connected to each other on the side of the isolation structure 200 facing away from the substrate 100 .

[0042] In these optional embodiments, the encapsulation parts 401 corresponding to the light-emitting units 330 of the same color are connected to each other on the isolation structure 200. The light-emitting units 330 of the same color can be manufactured and formed in the same process step, and when the light-emitting material layer and the encapsulation material layer of the non-target area are removed, the encapsulation parts 401 corresponding to the adjacent light-emitting units 330 of the same color are not gap-formed, and they are kept connected to each other in one piece, thereby simplifying the manufacturing process of the display panel.

[0043] Optionally, the encapsulation parts 401 corresponding to at least two adjacent light-emitting units 330 of the same color are integrally formed on the side of the isolation structure 200 away from the substrate 100. Please refer to the above, by not forming a gap between the encapsulation parts 401 corresponding to the adjacent light-emitting units 330 of the same color, at least two adjacent light-emitting units 330 of the same color corresponding to the encapsulation parts 401 are integrally formed on the side of the isolation structure 200 away from the substrate 100, that is, the same encapsulation part 401 corresponds to at least two adjacent light-emitting units 330 of the same color, and the at least two adjacent light-emitting units 330 of the same color are encapsulated, which can not only improve the connection strength between adjacent encapsulation parts 401, but also simplify the preparation process.

[0044] Optional, such as Figure 2As shown, the encapsulation parts 401 corresponding to two adjacent light-emitting units 330 are connected to each other on the side of the isolation structure 200 facing away from the substrate 100 to form a connection area LD, and there is a gap between the connection area LD and the isolation structure 200. Optionally, part or all of the same encapsulation part 401 corresponding to two adjacent light-emitting units 330, which is located on the side of the isolation structure 200 facing away from the substrate, is the connection area LD. During the preparation process of the light-emitting unit 330, when the light-emitting material layer used to prepare the light-emitting unit 330 is patterned, the etching material can enter from the edge of the connection area LD between the connection area LD and the isolation structure 200, and pattern the light-emitting material layer, and the etching material can also enter from the gap between the connection area LD and the isolation structure 200, thereby removing the redundant light-emitting material between the connection area LD and the isolation structure 200, so that a gap is formed between the connection area LD and the isolation structure 200.

[0045] Or, if Figure 4 As shown, a redundant unit is provided between the connection region LD and the isolation structure 200. During the preparation of the light-emitting unit 330, when the light-emitting material layer is patterned by a dry etching process, the light-emitting material and the conductive material provided between the connection region LD and the isolation structure 200 are not affected, so the part of the light-emitting material and the conductive material will be retained between the connection region LD and the isolation structure 200 to form a redundant unit. Optionally, the redundant unit includes two stacked sublayers, one of which is made of the same material as the light-emitting unit 330, and the other is made of the same material as the second electrode 700.

[0046] Optionally, a plurality of light-emitting units 330 of the same color are sequentially arranged along the first direction X to form a pixel column, and the encapsulation parts 401 corresponding to the plurality of light-emitting units 330 of the same color in the same pixel column are connected to each other on the side of the isolation structure 200 away from the substrate 100. The structure of the first encapsulation layer 400 can be further simplified, and the yield of the display panel can be improved.

[0047] In some optional embodiments, the light-emitting unit 330 includes a first light-emitting unit 331, a second light-emitting unit 332, and a third light-emitting unit 333 that emit different colors of light. The first light-emitting unit 331 can be used to emit red light, the second light-emitting unit 332 can be used to emit green light, and the third light-emitting unit 333 can be used to emit blue light, thereby realizing a color display of the display panel. In other embodiments, the first light-emitting unit 331 can also be used to emit green light or blue light, the second light-emitting unit 332 can be used to emit red light or blue light, and the third light-emitting unit 333 can also be used to emit red light or green light.

[0048] Optionally, the isolation opening 240 includes a first isolation opening 241, a second isolation opening 242 and a third isolation opening 243, and the pixel opening 320 includes a first pixel opening 311 connected to the first isolation opening 241, a second pixel opening 312 connected to the second isolation opening 242 and a third pixel opening 313 connected to the third isolation opening 243, the first pixel opening 311 is used to accommodate the first light-emitting unit 331, the second pixel opening 312 is used to accommodate the second light-emitting unit 332, and the third pixel opening 313 is used to accommodate the third light-emitting unit 333.

[0049] Optionally, the packaging parts 401 corresponding to at least two adjacent first light-emitting units 331 may be interconnected on the side of the isolation structure 200 facing away from the substrate 100, and / or the packaging parts 401 corresponding to at least two adjacent second light-emitting units 332 may be interconnected on the side of the isolation structure 200 facing away from the substrate 100, and / or the packaging parts 401 corresponding to at least two adjacent third light-emitting units 333 may be interconnected on the side of the isolation structure 200 facing away from the substrate 100.

[0050] There are many ways to arrange the first light emitting unit 331, the second light emitting unit 332 and the third light emitting unit 333. For example, a plurality of first light emitting units 331 are arranged side by side along the first direction X to form a first pixel column L1, a plurality of second light emitting units 332 are arranged side by side along the first direction X to form a second pixel column L2, a plurality of first light emitting units 331 are arranged side by side along the first direction X to form a third pixel column L3, and the first pixel column L1, the second pixel column L2 and the third pixel column L3 are arranged alternately in sequence along the second direction Y. Thus, the first light emitting unit 331, the second light emitting unit 332 and the third light emitting unit 333 can be arranged side by side along the second direction Y to form a display unit.

[0051] Optionally, the encapsulation parts 401 corresponding to the plurality of first light-emitting units 331 in the same first pixel column L1 are connected to each other on the side of the isolation structure 200 facing away from the substrate 100; and / or, the encapsulation parts 401 corresponding to the plurality of second light-emitting units 332 in the same second pixel column L2 are connected to each other on the side of the isolation structure 200 facing away from the substrate 100; and / or, the encapsulation parts 401 corresponding to the plurality of third light-emitting units 333 in the same third pixel column L3 are connected to each other on the side of the isolation structure 200 facing away from the substrate 100. This further simplifies the structure of the first encapsulation layer 400.

[0052] For example, the packaging parts 401 corresponding to the multiple first light-emitting units 331 in the first pixel column L1 are connected to each other on the side of the isolation structure 200 facing away from the substrate 100, that is, the multiple first light-emitting units 331 in the first pixel column L1 are packaged by the same packaging part 401. In the preparation process of the first light-emitting units 331, it is not necessary to perform patterning between the multiple first light-emitting units 331 in the first pixel column L1, and it is sufficient to remove the first light-emitting material layer and the first packaging material layer in the area where the second isolation opening 242 and the third isolation opening 243 between two first pixel columns L1 are located, which can greatly simplify the preparation process.

[0053] Similarly, the packaging parts 401 corresponding to the multiple second light-emitting units 332 in the second pixel column L2 are connected to each other on the side of the isolation structure 200 facing away from the substrate 100. During the preparation of the second light-emitting units 332, it is not necessary to perform patterning between the multiple second light-emitting units 332 in the second pixel column L2. It is sufficient to remove the second light-emitting material layer and the second packaging material layer in the area where the first isolation opening 241 and the third isolation opening 243 between the two columns of second pixel columns L2 are located. This can greatly simplify the preparation process.

[0054] Similarly, the packaging parts 401 corresponding to the multiple third light-emitting units 333 in the third pixel column L3 are interconnected on the side of the isolation structure 200 facing away from the substrate 100. During the preparation process of the third light-emitting units 333, it is not necessary to perform patterning between the multiple third light-emitting units 333 in the third pixel column L3. It is sufficient to remove the third light-emitting material layer and the third packaging material layer in the area where the first isolation opening 241 and the second isolation opening 242 between two columns of third pixel columns L3 are located. This can greatly simplify the preparation process.

[0055] In some other optional embodiments, such as Figure 5 and Figure 6 As shown, the first light-emitting units 331 and the second light-emitting units 332 are alternately arranged along the first direction X to form a fourth pixel column L4, and a plurality of third light-emitting units 333 are arranged in sequence along the first direction X to form a fifth pixel column L5, and the packaging parts 401 corresponding to the plurality of third light-emitting units 333 in the same fifth pixel column L5 are interconnected on the side of the isolation structure 200 facing away from the substrate 100.

[0056] In these optional embodiments, the first light-emitting units 331 and the second light-emitting units 332 are alternately arranged along the first direction X, and the plurality of first light-emitting units 331 are not adjacent to each other, and the plurality of second light-emitting units 332 are not adjacent to each other, so the packaging parts 401 corresponding to the plurality of first light-emitting units 331 are not connected to each other. The plurality of third light-emitting units 333 are arranged to form a fifth pixel column L5, and the third light-emitting units 333 in the fifth pixel column L5 are adjacently arranged, so the packaging parts 401 corresponding to the plurality of third light-emitting units 333 in the same fifth pixel column L5 are connected to each other on the side of the isolation structure 200 away from the substrate 100, so as to simplify the structure of the first packaging layer 400.

[0057] Optionally, the first light-emitting unit 331 and the second light-emitting unit 332 arranged along the first direction X form a pixel group, and the pixel group and the third light-emitting unit 333 are arranged side by side along the second direction Y to reduce the spacing between the first light-emitting unit 331, the second light-emitting unit 332 and the third light-emitting unit 333 in the display unit for forming white light, thereby improving the display effect.

[0058] Optionally, the fourth pixel column and the fifth pixel column L5 are alternately arranged along the second direction Y, so that a plurality of light-emitting units 330 of different colors can be distributed more evenly, thereby improving the uniformity of color rendering of the display panel.

[0059] In some optional embodiments, such as Figure 3 , Figure 5 and Figure 6 As shown, the packaging parts 401 corresponding to the light-emitting units 330 of different colors are arranged at intervals on the orthographic projection of the substrate 100 .

[0060] In these optional embodiments, the packaging parts 401 corresponding to the light-emitting units 330 of different colors can be prepared and formed in different process steps, so that the packaging parts 401 corresponding to the light-emitting units 330 of different colors can be arranged at intervals from each other.

[0061] In some optional embodiments, such as Figures 1 to 6 As shown, the packaging portion 401 covers the side wall of the isolation structure 200 facing the isolation opening 240 and extends to the side of the isolation structure 200 away from the substrate 100, and the packaging portions 401 corresponding to the light-emitting units 330 of different colors are spaced apart on the side of the isolation structure 200 away from the substrate 100.

[0062] In these optional embodiments, when the packaging part 401 corresponding to the light-emitting units 330 of different colors are prepared in different process steps, the packaging part 401 can be etched on the side of the isolation structure 200 away from the substrate 100, which can expand the distribution area of ​​the packaging part 401 and improve the packaging effect of the packaging part 401.

[0063] Optionally, as shown above, the light-emitting unit 330 may include a first light-emitting unit 331, a second light-emitting unit 332, and a third light-emitting unit 333 of different colors, and the encapsulation part 401 includes a first encapsulation part 410 for encapsulating the first light-emitting unit 331, a second encapsulation part 420 for encapsulating the second light-emitting unit 332, and a third encapsulation part 430 for encapsulating the third light-emitting unit 333, wherein the first encapsulation part 410 and the second encapsulation part 420 are arranged at intervals on the side of the isolation structure 200 away from the substrate 100, and / or the first encapsulation part 410 and the third encapsulation part 430 are arranged at intervals on the side of the isolation structure 200 away from the substrate 100, and / or the third encapsulation part 430 and the second encapsulation part 420 are arranged at intervals on the side of the isolation structure 200 away from the substrate 100. That is, the encapsulation parts 401 corresponding to the light-emitting units 330 of different colors can be arranged at intervals.

[0064] Optionally, the display panel further includes a second encapsulation layer 510, which is located on the side of the first encapsulation layer 400 away from the substrate 100, and the second encapsulation layer 510 contacts the isolation structure 200 via the gap between adjacent encapsulation parts 401. The contact area between the second encapsulation layer 510 and the bottom film layer can be increased, and the second encapsulation layer 510 can provide more complete protection for the encapsulation part 401, thereby improving the technical problem that the encapsulation part 401 is easy to peel off.

[0065] Optionally, the display panel further includes a third encapsulation layer 520, and the third encapsulation layer 520 is located on a side of the second encapsulation layer 510 away from the substrate 100. By adding the third encapsulation layer 520, the sealing effect can be further improved.

[0066] Optionally, the material of the second encapsulation layer 510 includes an organic material, which can improve the flatness of the second encapsulation layer 510 .

[0067] Optionally, the material of the third encapsulation layer 520 includes an inorganic material, so as to improve the compactness of the third encapsulation layer 520 and improve the encapsulation effect.

[0068] Optionally, the material of the first encapsulation layer 400 includes an inorganic material, so that the encapsulation layer has good compactness and encapsulation effect.

[0069] In some optional embodiments, such as Figure 1 , Figure 7 and Figure 8As shown, the display panel also includes a driving device layer, a planarization layer 120 and a first electrode layer 600. The driving device layer is arranged on one side of the substrate 100 and includes a driving circuit 110. The planarization layer 120 is arranged on the side of the driving device layer away from the substrate 100. The planarization layer 120 includes a first via hole 121 that is arranged through. The first electrode layer 600 is located on the side of the planarization layer 120 away from the substrate 100. The first electrode layer 600 includes a first electrode 610. The first electrode 610 is electrically connected to the driving circuit 110 via the first via hole 121.

[0070] In these optional embodiments, the area where the first via hole 121 is located may cause the film layer to be uneven. The first via hole 121 and the packaging part 401 are staggered to reduce the impact of the first via hole 121 on the flatness of the packaging part 401 and further improve the yield of the packaging part 401.

Among them, the orthographic projections of at least two adjacent light-emitting units 330 on the substrate are located within the orthographic projection of the same encapsulation part 401 on the substrate, that is, at least two adjacent light-emitting units 330 are encapsulated by the same encapsulation part 401.

The area where the first via 121 is located may cause the problem of uneven film layer.
