[0051] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0052] This application provides a display panel. Please refer to FIG1, which is a top view of a display panel provided in this application embodiment. The display panel 000 may have an opening area 00a, a display area 00b located around the opening area 00a, and a transition area 00c located between the opening area 00a and the display area 00b.

[0053] In this application, for a display device integrating such a display panel 000, various sensor components such as a camera and a light sensor can be placed on the back side of the display panel 000, and the photosensitive surface of the sensor components can face the opening area 00a of the display panel 000. For example, the light-incident surface of the camera in this display device can face the opening area 00a of the display panel 000, so that ambient light can pass through the opening area 00a of the display panel 000 and enter the light-incident surface of the camera, enabling the camera to acquire images normally. Here, the back side of the display panel 000 refers to the side opposite to the display surface of the display panel 000.

[0054] Please refer to Figures 2 and 3. Figure 2 is a schematic diagram of the film layer structure of the display panel shown in Figure 1 at point A-A', and Figure 3 is a partially enlarged view of the film layer structure of the display panel shown in Figure 2. The display panel 000 may include: a substrate 100, an insulator 300, a first electrode layer 400, and a plurality of conductive isolation pillars 200.

[0055] The plurality of conductive isolation pillars 200 in the display panel 000 can be located on one side of the substrate 100. Here, the plurality of conductive isolation pillars 200 in the display panel 000 can be located on the side of the substrate 100 facing the display surface of the display panel 000. The plurality of conductive isolation pillars 200 in the display panel 000 can be evenly distributed within the transition region 00c of the display panel 000, and the conductive isolation pillars 200 in the display panel 000 can be distributed in a ring shape and surrounding the opening region 00a.

[0056] As shown in Figure 3, the display panel 000 may further include an organic light-emitting layer 500. Here, the organic light-emitting layer 500 is typically formed by a vapor deposition process. Therefore, the organic light-emitting layer 500 can be located either within the display area 00b or within the transition area 00c. The portion of the organic light-emitting layer 500 located within the display area 00b can emit light, enabling the display area 00b of the display panel 000 to display an image normally. The portion of the organic light-emitting layer 500 located within the transition area 00c may include a first organic redundancy portion 501 disposed on the side of the conductive isolation pillar 200 facing away from the substrate 100, and a second organic redundancy portion 502 located between two adjacent conductive isolation pillars 200. It should be noted that the conductive isolation pillar 200 has a partition groove on its side, therefore, the first organic redundancy portion 501 and the second organic redundancy portion 502 in the organic light-emitting layer 500 can be disconnected through this partition groove. That is, the portion of the organic light-emitting layer 500 distributed within the transition area 00c is no longer a continuously arranged film structure. In this way, water and oxygen from the external environment are less likely to penetrate into the interior of the display panel 000 through the opening area 00a along the organic light-emitting layer 500.

[0057] The first electrode layer 400 in the display panel 100 may be located on the side of the plurality of conductive isolation pillars 200 facing away from the substrate 100. The organic light-emitting layer 500 may be located on the side of the first electrode layer 400 facing the substrate 100 and may be in direct contact with the first electrode layer 400. Here, the first electrode layer 400 may be an electrode layer disposed as a single layer; for example, the first electrode layer 400 may be a cathode electrode layer. Exemplarily, the first electrode layer 400 may be located on the side of the organic light-emitting layer 500 facing away from the substrate 100.

[0058] As shown in Figure 3, the display panel 000 may further include an encapsulation layer 600. Here, the encapsulation layer 600 may be located on the side of the first electrode layer 400 away from the substrate 100, and the encapsulation layer 600 may be used to encapsulate the organic light-emitting layer 500 to prevent water and oxygen in the external environment from corroding the organic light-emitting layer 500 from the display side of the display panel 000.

[0059] Although setting multiple conductive isolation pillars 200 can ensure that the portion of the organic light-emitting layer 500 distributed within the transition region 00c is no longer a continuously arranged film structure, making it less likely for the portion of the organic light-emitting layer 500 distributed within the transition region 00c to absorb water and oxygen from the external environment entering through the opening region 00a of the display panel 000, a small amount of water and oxygen will still enter through the opening region 00a of the display panel 000 into the via region 00c.

[0060] It should be noted that the portion of the first electrode layer 400 located on the side of the conductive isolation pillar 200 facing away from the substrate 100 and the portion located between two adjacent conductive isolation pillars 200 can also be disconnected by a partition groove provided on the side of the conductive isolation pillar 200. However, the conductive isolation pillar 200 is conductive, and the portion of the first electrode layer 400 located between two adjacent conductive isolation pillars 200 can extend into the partition groove of the conductive isolation pillar 200 to be electrically connected to the conductive isolation pillar 200. Therefore, the portions of the first electrode layer 400 located within the transition region 00c are electrically connected to each other.

[0061] In this case, if the portion of the first electrode layer 400 located in the display area 00a is not isolated from the portion of the first electrode layer 400 located in the transition area 00c, the portion of the first electrode layer 400 located in the transition area 00c will also be charged during the operation of the display panel 000.

[0062] Therefore, when the portion of the first electrode layer 400 located within the transition region 00c is charged, and water and oxygen from the external environment penetrate into the transition region 00b through the opening region 00a of the display panel 000, the water and oxygen invading into the transition region 00b will undergo an electrolytic reaction under the action of the charged first electrode layer 400 to generate hydrogen ions and hydroxide ions. Furthermore, since the outermost part of the display panel 000 also integrates a polarizer to reduce ambient light reflectivity, and the polarizer is typically made of metal, the metal ions (e.g., potassium ions) in the polarizer readily combine with hydroxide ions. This results in the portion of the encapsulation layer 600 located within the transition region 00c being in a strongly alkaline environment formed by the combination of metal ions and hydroxide ions. This environment reacts with the silicon oxide in the encapsulation layer 600, leading to defects such as holes or expansion in the encapsulation layer 600. Consequently, this affects the encapsulation effect of the encapsulation layer 600 on the organic light-emitting layer 500, resulting in lower reliability of the display panel 000.

[0063] In this application, at least one of the plurality of conductive isolation pillars 200 may be a first conductive isolation pillar 201. The first conductive isolation pillar 201 in the display panel 000 may have a first isolation groove K1 on its inner ring side facing the opening area 00a and / or its outer ring side facing the display area 00b. The insulator 300 in the display panel 000 may be located within the first isolation groove K1 of the first conductive isolation pillar 201.

[0064] The first electrode layer 400 in the display panel 000 may include: a first portion 401 located on the side of the first conductive isolation pillar 201 facing away from the substrate 100, and a second portion 402 and a third portion 403 located on both sides of the first portion 401. The first portion 401 in the first electrode layer 400 may be isolated from the second portion 402 and from the third portion 403. Here, the first portion 401 and the second portion 402 in the first electrode layer 400 may be isolated by a first isolation groove K1 provided on the inner ring side of the first conductive isolation pillar 201 facing the opening area 00a; the first portion 401 and the third portion 403 in the first electrode layer 400 may be isolated by the first isolation groove K1 provided on the inner ring side of the first conductive isolation pillar 201 facing the opening area 00a.

[0065] At least one of the second portion 402 and the third portion 403 of the first electrode layer 400 can be insulated from the first conductive isolation post 200 by the insulator 300. In this way, the portion of the first electrode layer 400 located on the side of the first conductive isolation post 201 facing the opening area 00a can be disconnected from the portion of the first electrode layer 400 located within the display area 00b. Therefore, even when the portion of the first electrode layer 400 located within the display area 00b is powered on, the portion of the first electrode layer 400 located on the side of the first conductive isolation post 201 facing the opening area 00a can be kept uncharged. This effectively prevents the electrolytic reaction of water and oxygen entering the transition area 00c, ensuring a good encapsulation effect of the encapsulation layer 600 in the display panel 000, and thus effectively improving the reliability of the display panel 000.

[0066] For example, in the first electrode layer 400, the second portion 402 is closer to the display area 00b of the display panel 000 than the first portion 401, and in the first electrode layer 400, the third portion 403 is closer to the opening area 00a of the display panel 000 than the first portion 401.

[0067] The distribution of the first partition groove K1 of the first conductive isolation post 200 in the display panel 000 can have the following three cases:

[0068] In the first scenario, the inner ring side of the first conductive isolation pillar 200 in the display panel 000 facing the opening area 00a may have a first isolation groove K1, while the outer ring side facing the display area 00b may not have the first isolation groove K1. In this way, the third portion 403 of the first electrode layer 400 can be insulated from the first conductive isolation pillar 201 by the insulator 300, and the second portion 402 of the first electrode layer 400 can be in contact with the first conductive isolation pillar 201 for conduction. Therefore, when the portion of the first electrode layer 400 located within the display area 00b is energized, the second portion 402 and the first conductive isolation pillar 200 of the first electrode layer 400 can be energized, while the third portion 403 of the first electrode layer 400 can be de-energized.

[0069] In the second scenario, the outer ring side P2 of the first conductive isolation pillar 200 in the display panel 000 facing the display area 00b may have a first isolation groove K1, while the inner ring side facing the opening area 00a may not have a first isolation groove K1. In this way, the second portion 402 of the first electrode layer 400 can be insulated from the first conductive isolation pillar 201 by the insulator 300, and the third portion 403 of the first electrode layer 400 can be in contact with the first conductive isolation pillar 201. Therefore, when the portion of the first electrode layer 400 located within the display area 00b is energized, the second portion 402 of the first electrode layer 400 can be energized, while the third portion 403 and the first conductive isolation pillar 201 can be de-energized.

[0070] In the third scenario, the inner ring side of the first conductive isolation pillar 200 in the display panel 000 facing the opening area 00a can have a first isolation groove K1, and the outer ring side facing the display area 00b can also have a first isolation groove K1. In this way, the second portion 402 in the first electrode layer 400 can be insulated from the first conductive isolation pillar 201 by the insulator 300, and the third portion 403 in the first electrode layer 400 can also be insulated from the first conductive isolation pillar 201 by the insulator 300. Therefore, when the portion of the first electrode layer 400 located within the display area 00b is energized, the second portion 402 in the first electrode layer 400 can be energized, while the third portion 403 and the first conductive isolation pillar 201 can be de-energized.

[0071] In this application, under any of the three conditions mentioned above, when the portion of the first electrode layer 400 located within the display area 00b is powered on, the third portion 403 of the first electrode layer 400 is not charged. That is, the portion of the first electrode layer 400 located on the side of the first conductive isolation pillar 201 facing the opening area 00a is not charged. This effectively avoids the electrolytic reaction of water and oxygen that have entered the transition area 00c, ensuring the encapsulation effect of the encapsulation layer 600 and thus effectively improving the reliability of the display panel 000.

[0072] It should be noted that the embodiments in this application are illustrated by taking the example that the inner ring side of the first conductive isolation post 200 facing the opening area 00a and the outer ring side facing the display area 00b both have the first isolation groove K1.

[0073] In summary, this application provides a display panel comprising: a substrate, an insulator, a first electrode layer, and a plurality of conductive isolation pillars. The plurality of conductive isolation pillars can be located within a transition region of the display panel, and at least one of the first conductive isolation pillars can have a first isolation groove. The insulator in the display panel can be located within the first isolation groove. Thus, at least one of the second and third portions of the first electrode layer can be insulated from the first conductive isolation pillar by the insulator, allowing the portion of the first electrode layer located on the side of the first conductive isolation pillar facing the opening region to be disconnected from the portion of the first electrode layer located within the display region. Therefore, even when the portion of the first electrode layer located within the display region is powered on, the portion of the first electrode layer located on the side of the first conductive isolation pillar facing the opening region can be kept uncharged, effectively preventing the electrolytic reaction of water and oxygen entering the transition region, ensuring the encapsulation effect of the encapsulation layer, and thus effectively improving the reliability of the display panel.

[0074] Optionally, please refer to Figure 4, which is a schematic diagram of the film layer structure of the transition region of a display panel according to an embodiment of this application. The display panel 000 may further include a first annular support pillar 701 corresponding to the first conductive isolation pillar 201. The first annular support pillar 701 in the display panel 000 may be closer to the substrate 100 relative to the corresponding first conductive isolation pillar 201. The orthographic projection of the first annular support pillar 701 on the substrate 100 may lie within the orthographic projection of the first conductive isolation pillar 201 on the substrate 100.

[0075] In this application, as shown in FIG5, FIG5 is a partially enlarged view of the film layer structure of the display panel shown in FIG4. The first conductive isolation pillar 201 in the display panel 000 may include: a conductive body portion 2011 that is in contact with the outer surface of the first annular pillar 701, a first isolation portion 2012 that is connected to the side of the conductive body portion 2011 facing the opening area 00a of the display panel 000, and a second isolation portion 2013 that is connected to the side of the conductive body portion 2011 facing the display area 00b of the display panel 000.

[0076] The first annular support column 701, corresponding to the first conductive isolation column 201, can be located between the first isolation portion 2012 and the second isolation portion 2013 in the first conductive isolation column 201. Furthermore, both the side of the first isolation portion 2012 facing away from the first annular support column 701 and the side of the second isolation portion 2013 facing away from the first annular support column 701 have a first partition groove K1.

[0077] It should be noted that the orthographic projection of the first annular pillar 701 onto the substrate 100 can lie within the orthographic projection of the conductive body portion 2011 of the corresponding first conductive isolation pillar 201 onto the substrate 100, and the conductive body portion 2011 can completely cover the corresponding first annular pillar 701. The first isolation portion 2012 and the second isolation portion 2013 in the first conductive isolation pillar 201 can both be located on the side of the conductive body portion 2011 away from the first annular pillar 701. Therefore, the first partition groove K1 in the first isolation portion 2012 and the first partition groove K1 in the second isolation portion 2013 are respectively located on both sides of the first annular pillar 701.

[0078] Optionally, as shown in Figures 4 and 5, among the multiple conductive isolation pillars 200 in the display panel 000, the conductive isolation pillars 200 excluding the first conductive isolation pillars 201 are second conductive isolation pillars 202. The display panel 000 may further include a second annular support pillar 702 corresponding to the second conductive isolation pillar 202. The orthographic projection of the second conductive isolation pillar 202 onto the substrate 100 may lie within the orthographic projection of the corresponding second annular support pillar 702 onto the substrate 100. Furthermore, the height of the first annular support pillar 701 corresponding to the first conductive isolation pillar 201 may be greater than or equal to the height of the second annular support pillar 702 corresponding to the second conductive isolation pillar 202.

[0079] In this application, as shown in FIG5, the second conductive isolation post 202 in the display panel 000 may have a second isolation groove K2 on its inner ring side facing the opening area 00a and / or its outer ring side facing the display area 00b. It should be noted that this application is illustrated illustratively using the example where both the inner ring side facing the opening area 00a and the outer ring side facing the display area 00b of the second conductive isolation post 202 have the second isolation groove K2. Here, the second isolation groove K2 of the second conductive isolation post 202 can be used to isolate the portion of the first electrode layer 400 located within the transition area 00c.

[0080] The portion of the organic light-emitting layer 500 located within the transition region 00c in the display device can also be separated by the second partition groove K2, thus the portion of the organic light-emitting layer 500 located within the transition region 00c can be separated by the first partition groove K1 and the second partition groove K2.

[0081] In this embodiment, an insulator 300 is disposed in the first partition groove K1 of the first conductive isolation pillar 201, while no insulator 300 is disposed in the second partition groove K2 of the second conductive isolation pillar 202. Here, the insulator 300 located in the first partition groove K1 can be formed during the fabrication of the display panel 100, during the formation of an insulating layer on the side of the plurality of conductive isolation pillars 400 facing away from the substrate 100. In one possible implementation, the insulator 300 located in the first partition groove K1 can be formed simultaneously during the formation of the pixel definition layer on the side of the plurality of conductive isolation pillars 400 facing away from the substrate 100. That is, the pixel definition layer in the display panel 000 can be disposed in the same layer and made of the same material as the insulator 300 located in the first partition groove K1.

[0082] For example, the pixel definition layer in the display panel 000 can be used to define multiple pixel regions within the display area 00b of the display panel 000. Since the pixel definition layer is made of an organic material, during the fabrication of the pixel definition layer, an organic film layer can first be formed on the side of the multiple conductive isolation pillars 400 facing away from the substrate 100, and the side of the organic film layer facing away from the substrate 100 has good flatness. Then, the organic film layer is patterned to obtain a pixel definition layer that can define multiple pixel regions within the display area 00b of the display panel 000, and an insulator 300 located within the first isolation groove K1 can be obtained.

[0083] It should be noted that after the organic film layer is formed, it can fill not only the first isolation groove K1 of the first conductive isolation pillar 201, but also the second isolation groove K2 of the second conductive isolation pillar 202. Since the height of the first annular pillar 701 is greater than the height of the second annular pillar 702, and the orthographic projection of the first annular pillar 701 onto the substrate 100 lies within the orthographic projection of the conductive body portion 2011 of the corresponding first conductive isolation pillar 201 onto the substrate 100, while the orthographic projection of the second conductive isolation pillar 202 onto the substrate 100 can lie within the orthographic projection of the corresponding second annular pillar 702 onto the substrate 100, the position where the first isolation groove K1 is located in the first conductive isolation pillar 201 is closer to the substrate 100 than the position where the second isolation groove K1 is located in the second conductive isolation pillar 202. That is, the vertical distance between the position of the first isolation groove K1 in the first conductive isolation pillar 201 and the side of the organic film layer away from the substrate 100 is greater than the vertical distance between the position of the second isolation groove K2 in the second conductive isolation pillar 202 and the side of the organic film layer away from the substrate 100.

[0084] Therefore, the organic film layer has a larger thickness near the first partition groove K1 and a smaller thickness near the second partition groove K2. After patterning the organic film layer, theoretically, all portions distributed within the transition region 00c should be removed. However, because the organic film layer is thicker near the first partition groove K1, a residual portion remains within the first partition groove K1; this residual portion constitutes the insulator 300. Conversely, the organic film layer is thinner near the second partition groove K2, so no residual portion remains within the first partition groove K1. Therefore, the first partition groove K1 of the first conductive isolation pillar 201 contains the insulator 300, while the second partition groove K2 of the second conductive isolation pillar 202 does not contain the insulator 300.

[0085] Optionally, please refer to Figure 6, which is another partially enlarged view of the film structure of the display panel shown in Figure 4. The display panel 000 may further include a plurality of insulating functional layers 800 located on one side of the substrate 100. The plurality of conductive isolation pillars 200 in the display panel 000 may be located on the side of the plurality of insulating functional layers 800 facing away from the substrate 100. At least one insulating functional layer 800 of the plurality of insulating functional layers 800 in the display panel 000 near the first conductive isolation pillar 201 may have a first annular groove H1 and a second annular groove H2 nested together.

[0086] Specifically, the first annular support pillar 701 in the display panel 000 can be located between the first annular groove H1 and the second annular groove H2, and at least a portion of the first isolation portion 2012 of the first conductive isolation pillar 201 can be located within the first annular groove H1, and at least a portion of the second isolation portion 2013 can be located within the second annular groove H2. That is, the first annular groove H1 can be located on the side of the first conductive isolation pillar 201 facing the opening area 00a of the display panel 000, and the second annular groove H2 can be located on the side of the first conductive isolation pillar 201 facing the display area 00b of the display area 000.

[0087] Here, since at least a portion of the first isolation portion 2012 can be located within the first annular groove H1, and at least a portion of the second isolation portion 2013 can be located within the second annular groove H2, the first isolation groove K1 of the first isolation portion 2012 can be located within the first annular groove H1, and the first isolation groove K1 of the second isolation portion 2013 can be located within the second annular groove H2. This further increases the distance between the first isolation groove K1 of the first conductive isolation pillar 201 and the side of the organic film layer facing away from the substrate 100, resulting in a greater thickness of the organic film layer near the first isolation groove K1. Consequently, after patterning the organic film layer, more residual portion remains in the first isolation groove K1, further improving the insulation effect between the second portion 402 and the third portion 403 of the first electrode layer 400 and the first conductive isolation pillar 201 via the insulator 300.

[0088] It should be noted that the heights of the first annular groove H1 and the second annular groove H2 can be the same. For example, the height D1 of the first annular groove H1 and the second annular groove H2 can be between 0.5 micrometers and 1.5 micrometers. For example, the height D1 of the first annular groove H1 and the second annular groove H2 can be 0.9 micrometers. In this way, the first isolation portion 2012 located in the first annular groove H1 and the second isolation portion 2013 located in the second annular groove H2 can be in the same plane in a direction parallel to the substrate 100.

[0089] In this application, as shown in FIG6, the first annular support 701 in the display panel 000 may include: at least one first annular electrode 7011, and a first annular insulating portion 7012 disposed in contact with the first annular electrode 7011. The first annular insulating portion 7012 in the first annular support 701 may be a part of the insulating functional layer 800 in the display panel 000.

[0090] Optionally, as shown in FIG6, the second annular support 702 in the display panel 000 may include: at least one second annular electrode 7021, and a second annular insulating portion 7022 disposed in contact with the second annular electrode 7021. The second annular insulating portion 7022 in the second annular support 702 may also be a part of the insulating functional layer 800.

[0091] It should be noted that the side of the first annular electrode 7011 facing away from the substrate 100 in the first annular support 701 may have a first annular insulating portion 7012, and the side of the first annular electrode 7011 facing the substrate 100 may also have a first annular insulating portion 7012. That is, the first annular support 701 may be composed of alternating first annular electrodes 7011 and first annular insulating portions 7012.

[0092] Similarly, the side of the second annular electrode 7021 facing away from the substrate 100 in the second annular support 702 may have a second annular insulating portion 7022, and the side of the second annular electrode 7021 facing the substrate 100 may also have a second annular insulating portion 7022. That is, the second annular support 702 may be composed of alternating second annular insulating portions 7022 and second annular insulating portions 7022.

[0093] It should be noted that when multiple first conductive isolation pillars 201 are distributed within the transition region 00c, and when two of the multiple first conductive isolation pillars 201 are arranged adjacently, the orthographic projection of any one of the first annular pillars 701 on the substrate 100 needs to be located within the orthographic projection of the corresponding conductive body portion 2011 on the substrate 100. Therefore, for the two first annular pillars 701 corresponding to the two adjacent first conductive isolation pillars 201, the two first annular electrodes 7011 belonging to these two first annular pillars 701 and arranged in the same layer need to be separated, and the two first annular insulating portions 7012 belonging to these two first annular pillars 701 and belonging to the same insulating functional layer 800 also need to be separated.

[0094] In the transition region 00c, multiple second conductive isolation pillars 202 are distributed. When there are two adjacent second conductive isolation pillars 202, the orthographic projection of any second conductive isolation pillar 202 on the substrate 100 needs to be within the orthographic projection of the corresponding second annular support pillar 702 on the substrate 100. Therefore, for the two first annular supports 701 corresponding to the two adjacent second conductive isolation pillars 201, the two second annular electrodes 7011 belonging to these two second annular supports 702 and arranged in the same layer need to be separated. However, the two second annular insulating portions 7012 belonging to these two second annular supports 702 and belonging to the same insulating functional layer 800 can be connected. That is, there is also a connecting portion between these two second annular insulating portions 7012 in the same insulating functional layer 800, and these two second annular insulating portions 7012 can be connected through the connecting portion.

[0095] Optionally, the number of first annular electrodes 7011 in the first annular support 701 can be greater than the number of second annular electrodes 7021 in the second annular support 702. Similarly, the number of first annular insulating portions 7012 in the first annular electrode 701 can also be greater than the number of second annular insulating portions 7022 in the second annular electrode 702. Thus, the height of the first annular support 701 can be greater than the height of the second annular support 702. This results in a thicker organic film layer near the first partition groove K1 and a thinner layer near the second partition groove K2, further ensuring that after patterning the organic film layer and completely removing the organic film layer remaining in the second partition groove K2 of the second conductive isolation pillar 202, an organic film layer will still remain in the first partition groove K1 of the first conductive isolation pillar 201 to form the insulator 300.

[0096] For example, as shown in FIG7, FIG7 is another partial enlarged view of the film layer structure of the display panel shown in FIG4. The first annular pillar 701 in the display panel 000 may include: a first annular electrode 7011a, a first annular electrode 7011b and a first annular electrode 7011c stacked in a direction away from the substrate 100, a first annular insulating portion 7012a, a first annular insulating portion 7012b and a first annular insulating portion 7012c respectively located on the side of the three first annular electrodes away from the substrate 100, and a first annular insulating portion 7012d located on the side of the first annular electrode 7011a facing the substrate 100.

[0097] The second annular support 702 in the display panel 000 may include: a second annular electrode 7021a and a second annular electrode 7021b stacked in a direction away from the substrate 100, a second annular insulating portion 7022a and a second annular insulating portion 7022b respectively located on the side of the two second annular electrodes away from the substrate 100, and a second annular insulating portion 7022c located between the second annular electrode 7021a and the substrate 100.

[0098] In this case, as shown in Figure 7, the first annular pillar 701 includes three first annular electrodes 7011, and the second annular pillar 702 includes two second annular electrodes 7021. The distance D2 between the conductive body portion 2011 of the first conductive isolation pillar 201 and the substrate 100 on the side facing away from the substrate 100 can be between 3 micrometers and 4 micrometers. For example, the distance D2 between the first conductive isolation pillar 201 and the substrate 100 on the side facing away from the substrate 100 can be 3.51 micrometers. The distance D3 between the second conductive isolation pillar 202 and the substrate 100 on the side facing away from the substrate 100 can be between 1.5 micrometers and 2.5 micrometers. For example, the distance D3 between the second conductive isolation pillar 202 and the substrate 100 on the side facing away from the substrate 100 can be 2.33 micrometers.

[0099] It should be noted that, as shown in Figure 7, for two adjacent first annular electrodes 7011 arranged in the direction perpendicular to the substrate 100 within the first annular support 701, the width of the first annular electrode 7011 closer to the substrate 100 is greater than the width of the first annular electrode 7011 further away from the substrate 100. For example, the width of the first annular electrode 7011a is greater than the width of the first annular electrode 7011b; the width of the first annular electrode 7011b is greater than the width of the first annular electrode 7011c. For instance, the width D4 of the first annular electrode 7011a in the first annular support 701 can be between 1.5 micrometers and 2.5 micrometers; for example, the width D4 of the first annular electrode 7011a can be 2 micrometers, while the widths of the first annular electrodes 7011b and 7011c are both less than 2 micrometers.

[0100] Similarly, for two adjacent first annular electrodes 7021 arranged in a direction perpendicular to the substrate 100 in the second annular pillar 702, the width of the second annular electrode 7021 closer to the substrate 100 is greater than the width of the second annular electrode 7021 further away from the substrate 100. For example, the width of the second annular electrode 7021a is greater than the width of the second annular electrode 7021b. For instance, the width D5 of the second annular electrode 7021a in the second annular pillar 702 can be between 3 micrometers and 5 micrometers; for example, the width D5 of the second annular electrode 7021a can be 4 micrometers, and the width of the second annular electrode 7021b can be less than 4 micrometers.

[0101] It should be noted that the width of the annular electrode in this application refers to the width of the cross-section of the annular electrode perpendicular to the substrate 100 and perpendicular to the extension direction of the annular electrode.

[0102] In one possible implementation, the cross-sectional shape of the first annular support 701 can be trapezoidal. This prevents the encapsulation layer 600 from easily breaking at the first annular support 701, thus ensuring the encapsulation effect of the encapsulation layer 600.

[0103] Optionally, at least one first annular electrode 7011 in the first annular support 701 may be disposed in the same layer as at least one second annular electrode 7021 in the second annular support 702 and made of the same material.

[0104] For example, when the first annular support 701 includes three first annular electrodes 7011 and the second annular support 702 includes two second annular electrodes 7021, the first annular electrode 7011a in the first annular support 701 can be disposed in the same layer and made of the same material as the second annular electrode 7021a in the second annular support 702, and the first annular electrode 7011b in the first annular support 701 can be disposed in the same layer and made of the same material as the second annular electrode 7021b in the second annular support 702.

[0105] It should be noted that the first annular insulating portion 7012a in the first annular support 701 can be disposed in the same layer and made of the same material as the second annular insulating portion 7022a in the second annular support 702, and the first annular insulating portion 7012d in the first annular support 701 can be disposed in the same layer and made of the same material as the second annular insulating portion 7022c in the second annular support 702.

[0106] In this application, please refer to Figure 8, which is a schematic diagram of the film layer structure of the transition region of a display panel provided in another embodiment of this application. The display panel 000 may further include an annular barrier 900 distributed within the transition region 00c of the display panel 000. The annular barrier 900 in the display panel 000 may be distributed around the opening region 00a of the display panel 000, that is, the annular barrier 900 may be annular. It should be noted that, in the direction parallel to the substrate 100, the width of the annular barrier 900 may gradually decrease along the direction of the annular barrier 900 away from the substrate 100.

[0107] It should be noted that the encapsulation layer 600 in the display panel 000 may include: an organic encapsulation layer 601, a first inorganic encapsulation layer 602, and a second inorganic encapsulation layer 603. The first inorganic encapsulation layer 602 in the encapsulation layer 600 may be closer to the substrate 100, and the organic encapsulation layer 601 may be located between the first inorganic encapsulation layer 602 and the second inorganic encapsulation layer 603. This ensures the effective encapsulation of the organic light-emitting layer 500 by the encapsulation layer 600.

[0108] In this application, the annular barrier 900 in the display panel 000 can block the organic encapsulation layer 601 within the encapsulation layer 600, preventing the organic encapsulation layer 601 from overflowing during its formation due to its strong fluidity. This ensures that the organic encapsulation layer 601 within the encapsulation layer 600 is only distributed within the display area 00b and does not flow across the annular barrier 900 towards the opening area 00a. In this way, the encapsulation layer 600 can effectively encapsulate the organic light-emitting layer 500 located within the display area 00b of the display panel 000.

[0109] Optionally, as shown in Figure 8, a portion of the conductive isolation pillars 200 in the display panel 000 may be located between the annular barrier 900 and the display area 00b of the display panel 000, and another portion of the conductive isolation pillars 200 in the display panel 000 may be located between the annular barrier 900 and the opening area 00a of the display panel 000.

[0110] In this design, at least one of the multiple conductive isolation pillars 200 in the display panel 000 located between the annular barrier 900 and the display area 00b of the display panel 000 can be a first conductive isolation pillar 201. That is, the first conductive isolation pillar 201 in the display panel 000 can be located between the annular barrier 900 and the display area 00b of the display panel 000. Furthermore, the conductive isolation pillars 200 located between the annular barrier 900 and the opening area 00a of the display panel 000 can all be second conductive isolation pillars 202. Thus, through the insulation of the first conductive isolation pillar 201 from the second portion 402 and the third portion 403 in the first electrode layer 400, even when the portion of the first electrode layer 400 located within the display area 00b is energized, the portion of the first electrode layer 400 located between the annular barrier 900 and the opening area 00a of the display panel 000 can remain unenergized. Therefore, the electrolysis of water and oxygen that have entered the transition zone 00c can be effectively avoided, ensuring the encapsulation effect of the encapsulation layer 600 in the display panel 000.

[0111] Optionally, as shown in FIG9, FIG9 is a partially enlarged view of the film layer structure of a display panel provided in an embodiment of the present application. The conductive isolation pillar 200 in the display panel 000 may include: a first annular conductive layer 200a, a second annular conductive layer 200b, and a third annular conductive layer 200c stacked together. The outer ring sides of the first annular conductive layer 200a and the third annular conductive layer 200c in the conductive isolation pillar 200 may both protrude beyond the outer ring side of the second annular conductive layer 200b. Thus, the first isolation groove K1 of the first isolation portion 2012 in the first conductive isolation pillar 201 may be located on the outer ring side of the second annular conductive layer 200b in the first conductive isolation pillar 201, and may be located between the first annular conductive layer 200a and the third annular conductive layer 200c. The inner ring sides of the first annular conductive layer 200a and the third annular conductive layer 200c in the conductive isolation pillar 200 may both protrude beyond the inner ring side of the second annular conductive layer 200b. Thus, the first isolation groove K1 of the second isolation portion 2013 in the first conductive isolation pillar 201 can be located on the inner ring side surface of the second annular conductive layer 200b in the first conductive isolation pillar 201, and can be located between the first annular conductive layer 200a and the third annular conductive layer 200c. Therefore, the first isolation groove K1 of the first conductive isolation pillar 201 can be located between the first annular conductive layer 200a and the third annular conductive layer 200c in a direction perpendicular to the substrate 100.

[0112] It should be noted that during the formation of the conductive isolation pillars 200 in the display panel 000, the isolation grooves of the conductive isolation pillars 200 can all be formed by the transition etching of the conductive isolation pillars 200. For example, the first annular conductive layer 200a and the third annular conductive layer 200c in the conductive isolation pillars 200 can both be made of titanium, and the second annular conductive layer 200b in the conductive isolation pillars 200 can be made of aluminum. Thus, during the etching process of the structure used to form the conductive isolation pillars 200, the etching rate of the first annular conductive layer 200a and the third annular conductive layer 200c is slower, while the etching rate of the second annular conductive layer 200b is faster. In this way, isolation grooves can be formed between the first annular conductive layer 200a and the third annular conductive layer 200c.

[0113] It should also be noted that, since the first conductive isolation post 201 includes a conductive body portion 2011 and a first isolation portion 2012 and a second isolation portion 2013 located on both sides of the conductive body portion 2011, and since the first isolation groove K1 of the first conductive isolation post 201 is formed on the side of the first isolation portion 2012 and the second isolation portion 2013 away from the conductive body portion 2011, while the second isolation groove K2 of the second conductive isolation post 202 is formed directly on the side of the entire second conductive isolation post 202, the structure of the first conductive isolation post 201 is easier to form an isolation groove compared to the structure of the second conductive isolation post 202, and the groove depth of the first isolation groove K1 of the first conductive isolation post 201 can be greater than the groove depth of the second isolation groove K2 of the second conductive isolation post 202. To this end, it is further ensured that during the removal of pixel definition adhesive in the transition area 00c of the display panel 000, after the pixel definition adhesive in the second partition groove K2 of the second conductive isolation pillar 202 is completely removed, pixel definition adhesive will still remain in the first partition groove K1 of the first conductive isolation pillar 201 to form an insulator 300.

[0114] As shown in FIG10, FIG10 is a schematic diagram of the film layer structure of the display area of ​​a display panel provided in an embodiment of the present application. The pixel definition layer 1100 in the display panel 000 can be used to define a plurality of pixel areas within the display area 00b of the display panel 000. The display panel 000 may further include: light-emitting devices 1200 located in each pixel area. The pixel definition layer 1100 in the display panel 000 may have a plurality of pixel openings V corresponding one-to-one with the plurality of light-emitting devices 1200, and each light-emitting device 1200 may be located within the corresponding pixel opening V. The display panel 000 may further include: a second electrode layer 1300 located on the side of the organic light-emitting layer 500 facing the substrate 100. For example, the second electrode layer 1300 in the display panel 000 may be an anode electrode layer. The portion of the first electrode layer 400 located within the pixel opening V, the portion of the organic light-emitting layer 500 located within the pixel opening V, and the portion of the second electrode layer 1300 located within the pixel opening V in the display panel 000 may constitute the light-emitting device 1200. The organic light-emitting layer 500 located within the pixel opening V can be situated between the first electrode layer 400 and the second electrode layer 1300. When the first electrode layer 400 and the second electrode layer 1300 are charged, the organic light-emitting layer 500 can emit light under the influence of the first electrode layer 400 and the second electrode layer 1300. The encapsulation layer 600 in the display panel 000 can encapsulate the light-emitting device 1200 to prevent water and oxygen from the external environment from corroding the light-emitting device 1200.

[0115] It should be noted that, as shown in Figure 10, the display panel 000 may further include a pixel driving circuit 1400 located within the display area 00b. The pixel driving circuit 1400 in the display panel 000 can be powered by the second electrode layer 1300 in the light-emitting device 1200.

[0116] The pixel driving circuit 1400 in the display panel 000 may include at least two transistors and at least one storage capacitor. The transistors in the pixel driving circuit 1400 may include an active layer 1401, a gate 1402, a first electrode 1043, and a second electrode 1044. One of the first electrode 1043 and the second electrode 1044 may be the source of the transistor, and the other may be the drain of the transistor. The first electrode 1043 of one of the transistors in the pixel driving circuit 1400 may be electrically connected to the anode of a corresponding light-emitting device via a transition electrode 1045. The storage capacitor in the pixel driving circuit 1400 may include a first capacitor electrode 1046 and a second capacitor electrode 1047 disposed opposite to each other.

[0117] For example, the adapter electrode 1045 can be disposed in the same layer as the conductive isolation pillar 200 in the above embodiment and be made of the same material.

[0118] The gate 1402 and the first capacitor electrode 1406 can be disposed in the same layer as the first ring electrode 7011a and the second ring electrode 7021a in the above embodiments and are made of the same material.

[0119] The second capacitor electrode 1047 can be disposed in the same layer as the first annular electrode 7011b and the second annular electrode 7011b in the above embodiments and be made of the same material.

[0120] As shown in Figure 10, the multiple stacked insulating functional layers 800 in the display panel 000 may include a first gate insulating layer 801, a second gate insulating layer 802, a third gate insulating layer 803, and an interlayer dielectric layer 804.

[0121] For example, the first gate insulating layer 801 may be disposed in the same layer and made of the same material as the first annular insulating portion 7012d and the second annular insulating portion 7022c in the above embodiments.

[0122] The second gate insulating layer 802 can be disposed in the same layer as the first annular insulating portion 7012a and the second annular insulating portion 7022a in the above embodiments and made of the same material.

[0123] The interlayer dielectric layer 804 can be disposed in the same layer as the first annular insulating portion 7012c and the second annular insulating portion 7022b in the above embodiments and be made of the same material.

[0124] Furthermore, the conductive layer located between the interlayer dielectric layer 804 and the third gate insulating layer 803 can be disposed in the same layer and made of the same material as the third annular electrode 7011 in the above embodiment. Here, the conductive layer between the interlayer dielectric layer 804 and the third gate insulating layer 803 can serve as a signal trace within the display area 00b, or as a peripheral trace located in a non-display area surrounding the display area 00b. This application does not limit this aspect.

[0125] It should be noted that the display panel 000 may further include: a first planarization layer 1501 and a second planarization layer 1502 stacked together. The first planarization layer 1501 in the display panel 000 may be located on the side of the conductive layer containing the first electrode 1043 and the second electrode 1044 of the transistor that faces away from the substrate 100; the second planarization layer 1502 in the display panel 000 may be located on the side of the conductive layer containing the transition electrode 1045 that faces away from the substrate 100. The second electrode layer 1300 in the display panel 000 may be located on the side of the second planarization layer 1502 that faces away from the substrate 100.

[0126] Optionally, as shown in Figures 4 and 10, the substrate 100 in the display panel 000 may include: a first flexible substrate 101, a first barrier layer 102, a second flexible substrate 103, and a second barrier layer 104 stacked together. A plurality of insulating functional layers 800 in the display panel 000 may be located on the side of the second barrier layer 104 facing away from the first flexible substrate 101.

[0127] In summary, this application provides a display panel comprising: a substrate, an insulator, a first electrode layer, and a plurality of conductive isolation pillars. The plurality of conductive isolation pillars can be located within a transition region of the display panel, and at least one of the first conductive isolation pillars can have a first isolation groove. The insulator in the display panel can be located within the first isolation groove. Thus, at least one of the second and third portions of the first electrode layer can be insulated from the first conductive isolation pillar by the insulator, allowing the portion of the first electrode layer located on the side of the first conductive isolation pillar facing the opening region to be disconnected from the portion of the first electrode layer located within the display region. Therefore, even when the portion of the first electrode layer located within the display region is powered on, the portion of the first electrode layer located on the side of the first conductive isolation pillar facing the opening region can be kept uncharged, effectively preventing the electrolytic reaction of water and oxygen entering the transition region, ensuring the encapsulation effect of the encapsulation layer, and thus effectively improving the reliability of the display panel.

[0128] This application embodiment also provides a display device, which may include a power supply component and a display panel. The power supply component in the display device can be used to supply power to the display panel, which can be the aforementioned display panel.

[0129] For example, the display device can be any product or component with display function, such as electronic paper, mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, navigator, etc.
