Display panel and display apparatus

Abstract

The present application belongs to the technical field of display. Disclosed are a display panel and a display apparatus. The display panel comprises: a driving backplane, an encapsulation layer, a touch electrode layer, a plurality of touch leads and a plurality of light-emitting devices. Since the part of the driving backplane in which a bearing recess is disposed has a relatively small overall thickness, during the process of using an open mask to deposit a thin film on the driving backplane so as to form an encapsulation layer, the probability of the open mask scraping against the part of the driving backplane in which the bearing recess is disposed is relatively low, thereby ensuring that the part of the driving backplane in which the bearing recess is disposed has better flatness. Thus, when subsequently forming touch leads in a non-display region of the display panel, the touch leads can be distributed in the bearing recess, such that the touch leads can be distributed in an area of the driving backplane with better flatness, thereby ensuring that the touch leads are not prone to adverse phenomena such as short circuits or breakage, making the display panel highly reliable.

[0063] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0064] Currently, existing touch-sensitive display panels typically use the FMLOC (Flexible Multi Layer On Cell) process to design a touch structure. The FMLOC process involves fabricating a metal grid electrode layer on the encapsulation layer of the display panel to achieve touch control.

[0065] However, the encapsulation layer of the display panel is typically formed by deposition using an open mask. During the process of using an open mask to produce the encapsulation layer in the display panel, the organic film layer in the display panel is typically thick. Therefore, during the movement of the open mask, the organic film layer in the non-display area of ​​the display panel is easily scratched by the open mask, resulting in a lower flatness of the organic film layer in the non-display area of ​​the display panel. Subsequently, when touch leads are formed on the organic film layer in the non-display area of ​​the display panel to electrically connect to the metal grid electrode layer, the touch leads are prone to short circuits or disconnections, resulting in lower reliability of the display panel.

[0066] Please refer to Figures 1, 2, 3, and 4. Figure 1 is a schematic diagram of a partial structure of a display panel provided in an embodiment of the present application. Figure 2 is a schematic diagram of the cross-sectional structure of the display panel shown in Figure 1 at line A-A'. Figure 3 is a partial enlarged view of the display panel shown in Figure 1 at line C. Figure 4 is a schematic diagram of the cross-sectional structure of the display panel shown in Figure 3 at line B-B'. The display panel 000 may include: a driving backplane 100, an encapsulation layer 300, a touch electrode layer 400, a plurality of touch leads 500, and a plurality of light-emitting devices 200. The display panel 000 may have a display area 00a and a non-display area 00b located outside the display area 00a.

[0067] The portion of the driver backplane 100 in the display panel 000 located within the non-display area 00b may have a bearing groove U. This ensures that the overall thickness of the portion of the driver backplane 100 provided with the bearing groove U is relatively small. The non-display area 00b of the display panel 000 may include a bending area 00c. The display panel 000 may further include at least one retaining wall 600 located within the non-display area 00b and surrounding the display area 00a. The bearing groove U in the driver backplane 100 may be distributed between the at least one retaining wall 600 and the bending area 00c.

[0068] In the present application, as shown in FIG1 , at least one retaining wall 600 in the display panel 000 may include: a first retaining wall 601 and a second retaining wall 602. The first retaining wall 601 may be closer to the display area 00a than the second retaining wall 602. That is, the first retaining wall 601 may be arranged around the display area 00a, and the second retaining wall 602 may be arranged around the first retaining wall 601. A bearing groove U may be located between the second retaining wall 602 and the bending area 00c. For example, the second retaining wall 602 may include: a first strip portion 602a and a second strip portion (not shown) arranged opposite each other. The first strip portion 602a and the second strip portion of the second retaining wall 602 may both extend parallel to the bending axis of the bending area 00c, and the first strip portion 602a of the second retaining wall 602 may be closer to the bending area 00c than the second strip portion. Here, the bearing groove U may be located between the first strip portion 602a of the second retaining wall 602 and the bending area 00c.

[0069] The multiple light-emitting devices 200 in the display panel 000 can be located on one side of the driving backplane 100. The multiple light-emitting devices 200 can be distributed within the display area 00a. The multiple light-emitting devices 200 can be electrically connected to the driving backplane 100, which can drive the multiple light-emitting devices 200 to emit light, allowing the display panel 000 to display the corresponding image.

[0070] The encapsulation layer 300 in the display panel 000 can be located on a side of the plurality of light-emitting devices 200 that is away from the driving backplane 100. Here, the encapsulation layer 300 can be used to encapsulate the light-emitting devices 200 to prevent water and oxygen in the external environment from corroding the light-emitting layer in the light-emitting devices 200, thereby increasing the service life of the light-emitting devices 200.

[0071] The touch electrode layer 400 in the display panel 000 can be located on the side of the encapsulation layer 300 in the display panel 000 that faces away from the driver backplane 100. Here, the touch electrode layer 400 can be a grid-like metal electrode layer. For example, the touch electrode layer 400 has a plurality of grid holes corresponding to the plurality of light-emitting devices 200. The orthographic projection of each light-emitting device 200 on the driver backplane 100 can be located within the orthographic projection of the corresponding grid hole on the driver backplane 100. In other words, the orthographic projection of the touch electrode layer 400 on the driver backplane 100 does not overlap with the orthographic projection of the light-emitting device 200 on the driver backplane 100. Therefore, even if the touch electrode layer 400 is made of an opaque metal material, it can ensure that the touch electrode layer 400 does not block the light-emitting device 200, allowing light emitted by the light-emitting device 200 to be transmitted through the corresponding grid holes in the touch electrode layer 400, thereby ensuring that the display panel 000 can display images normally.

[0072] The multiple touch leads 500 in the display panel 000 can be electrically connected to the touch electrode layer 400 in the display panel 000, and the multiple touch leads 500 in the display panel 000 can be distributed within the non-display area 00b of the display panel 000. For example, these touch leads 500 can be arranged between the second retaining wall 602 and the bending area 00c in the non-display area 00b of the display panel 000. Because the portion between the second retaining wall 602 and the bending area 00c in the driving backplane 100 has a supporting groove U, at least a portion of the multiple touch leads 500 in the display panel 000 can be distributed within the supporting groove U in the driving backplane 100. The extension direction of the touch leads 500 can be parallel to the bending axis of the bending area 00c. In other words, the extension direction of the touch leads 500 is parallel to the extension direction of the first strip portion 602a.

[0073] In the embodiment of the present application, since the overall thickness of the portion of the driver backplane 100 where the bearing groove U is provided is relatively small, when an open mask is used to deposit a thin film on the driver backplane 100 to form the encapsulation layer 300, the probability of the open mask scratching the portion of the driver backplane 100 where the bearing groove U is provided is relatively low, thereby ensuring that the portion of the driver backplane 100 where the bearing groove U is provided has good flatness. To this end, when the touch leads 500 are subsequently formed in the non-display area 00b of the display panel 000, these touch leads 500 can be distributed in the bearing groove U to ensure that these touch leads 500 can be distributed in the area of ​​the driver backplane 100 with good flatness, thereby ensuring that these touch leads 500 are not prone to adverse phenomena such as short circuits or disconnections, thereby making the reliability of this display panel 000 higher.

[0074] In summary, the display panel provided by the embodiment of the present application includes: a driving backplane, an encapsulation layer, a touch electrode layer, a plurality of touch leads and a plurality of light-emitting devices. Since the overall thickness of the portion of the driving backplane where the bearing groove is set is relatively small. Therefore, in the process of depositing a thin film on the driving backplane using an open mask plate to form the encapsulation layer, the probability of the open mask plate scratching the portion of the driving backplane where the bearing groove is set is low, thereby ensuring that the flatness of the portion of the driving backplane where the bearing groove is set is better. For this reason, when the touch leads are subsequently formed in the non-display area of ​​the display panel, these touch leads can be distributed in the bearing groove to ensure that these touch leads can be distributed on the area with better flatness in the driving backplane, thereby ensuring that these touch leads are not prone to adverse phenomena such as short circuits or disconnections, making this display panel more reliable.

[0075] In an embodiment of the present application, please refer to Figure 5, which is a schematic diagram of the film layer structure of a display panel in a non-display area provided in an embodiment of the present application. The driving backplane 100 in the display panel 000 may include: a substrate 101, and a plurality of stacked organic layers 102 located on one side of the substrate. Among them, the bearing groove U in the driving backplane 100 may include: a hollow area (not marked in the figure) distributed in at least one organic layer 102. Here, the hollow area in the organic layer 102 may be located between the bending area 00c and the second retaining wall 602. For this purpose, the hollow area in the organic layer 102 refers to: a structure obtained after at least part of the organic layer 102 between the bending area 00c and the second retaining wall 602 is removed. In this case, during the preparation of a certain organic layer 102, a corresponding hollow area can be formed to obtain a bearing groove U in the non-display area 00b. There is no need to complete the formation of all the organic layers 102 in the driving backplane 100 and then open a separate bearing groove U in the non-display area 00b of the driving backplane 100. This can effectively reduce the difficulty of forming the bearing groove U in the non-display area 00b of the driving backplane 100.

[0076] Here, as shown in FIG5 , the multiple stacked organic layers 102 in the display panel 000 may include a support layer 1021 and a pixel definition layer 1022. The pixel definition layer 1022 may be closer to the substrate 101 than the support layer 1021. The portion of the pixel definition layer 1022 of the display panel 000 located within the display area 00a may have multiple pixel openings corresponding one-to-one to the multiple light-emitting devices 200, and each light-emitting device 200 may be located within a corresponding pixel opening. The portion of the support layer 1021 of the display panel 000 located within the display area 00a may have multiple interconnecting openings corresponding one-to-one to the multiple pixel openings, wherein the orthographic projection of each pixel opening on the substrate 101 may be located within the orthographic projection of the corresponding interconnecting opening on the substrate 101, and the area of ​​the orthographic projection of the pixel opening on the substrate 101 is smaller than the area of ​​the orthographic projection of the interconnecting opening on the substrate 101. In the present application, the support layer 1021 of the display panel 000 is used to support the mask used in the subsequent film formation process. For example, in a process of using a fine evaporation mask to form a light-emitting layer in the light-emitting device 200 , the support layer 1021 of the display panel 000 may support the fine evaporation mask.

[0077] Optionally, the bearing groove U in the driving backplane 100 may include: a first hollow area U1 distributed in the supporting layer 1021, and a second hollow area U2 distributed in the pixel definition layer 1022, wherein the orthographic projection of the second hollow area U2 on the substrate 101 may be located within the orthographic projection of the first hollow area U1 on the substrate 101, and the first hollow area U1 may be connected to the second hollow area U2.

[0078] In this case, the thickness of the portion of the driving backplate 100 where the first hollow area U1 is distributed can be ensured to be relatively low, and the thickness of the portion of the driving backplate 100 where the second hollow area U2 is distributed can be ensured to be relatively low. In this way, in the subsequent process of depositing a thin film on the driving backplate 100 using an open mask to form the encapsulation layer 300, the probability of the open mask scratching the portion of the driving backplate 100 where the first hollow area U1 is distributed, and the probability of the open mask scratching the portion of the driving backplate 100 where the second hollow area U2 is distributed are both relatively low, thereby ensuring that the portion of the driving backplate 100 where the first hollow area U1 is distributed, and the portion of the driving backplate 100 where the second hollow area U2 is distributed have good flatness.

[0079] The orthographic projections of the multiple touch leads 500 in the display panel 000 on the substrate 101 may all be located within the orthographic projection of the first hollow area U1 on the substrate 101, and the orthographic projections of at least some of the touch leads 500 on the substrate 101 may be located within the orthographic projection of the second hollow area U2 on the substrate 101. In one possible implementation, the touch lead 500 closest to the bending area 00c among the multiple touch leads 500 may extend outside the second hollow area U2 of the pixel definition layer 1022, but the portion of this touch lead 500 extending from the second hollow area U2 will still be distributed within the first hollow area U1 of the support layer 1021.

[0080] It should be noted that because the first hollow area U1 is located within the portion of the support layer 1021 within the non-display area 00b, the thickness of the portion of the driver backplane 100 where the first hollow area U1 is located can be relatively low, reducing the probability of subsequent scraping of the open mask into the first hollow area U1, thereby ensuring good flatness within the first hollow area U1. Consequently, the touch leads 500 extending outside the second hollow area U2 and located within the first hollow area U1 are less susceptible to short circuits, breakage, and other adverse phenomena.

[0081] Furthermore, since the second hollow area U2 is distributed in the portion of the pixel definition layer 1022 located in the non-display area 00b, and the second hollow area U2 is connected to the first hollow area U1, the thickness of the portion of the driving backplane 100 where the first hollow area U1 and the second hollow area U2 are simultaneously provided can be ensured to be lower, so as to further reduce the probability of the open mask plate scratching the second hollow area U2, thereby ensuring better flatness of the portion of the driving backplane 100 where the first hollow area U1 and the second hollow area U2 are simultaneously provided, so that the touch lead 500 provided above this portion is less likely to suffer from adverse phenomena such as short circuit or breakage.

[0082] In the embodiment of the present application, as shown in FIG. 5 , the multiple stacked organic layers 102 in the display panel 000 may further include: a first planar layer 1023 located on the side of the pixel definition layer 1022 facing the substrate 101 .

[0083] The bearing groove U in the driving backplane 100 may also include: a third hollow area U3 distributed in the first flat layer 1023, the orthographic projection of the third hollow area U3 on the substrate 101 may be located within the orthographic projection of the second hollow area U2 on the substrate 101, and the third hollow area U3 may be connected to the second hollow area U2.

[0084] In this way, the overall thickness of the portion of the driver backplane 100 where the third hollow area U3 is located can be ensured to be smaller. Therefore, when a thin film is subsequently deposited on the driver backplane 100 using an open mask to form the encapsulation layer 300, the probability of the open mask scratching the portion where the third hollow area U3 is located can be further reduced, thereby ensuring better flatness of the portion of the driver backplane 100 where the third hollow area U3 is located.

[0085] The orthographic projections of at least some of the touch leads 500 on the substrate 101 may be located within the orthographic projections of the third hollow area U3 distributed within the first flat layer 1023 on the substrate 101. Since the portion of the third hollow area U3 distributed within the first flat layer 1023 of the driving backplane 100 has good flatness, when the orthographic projections of at least some of the touch leads 500 on the substrate 101 are located within the orthographic projections of the third hollow area U3 on the substrate 101, the probability of these touch leads 500 experiencing defects such as short circuits or disconnections can be reduced.

[0086] In the embodiment of the present application, please continue to refer to FIG. 5 . The multiple stacked organic layers 102 in the display panel 000 may further include: a second planar layer 1024 located between the pixel definition layer 1022 and the first planar layer 1023 .

[0087] The bearing recess U in the driver backplane 100 may further include a fourth hollow region U4 distributed within the second flat layer 1024. The orthographic projection of the fourth hollow region U4 on the substrate 101 may overlap with the orthographic projection of the third hollow region U3 on the substrate 101, and the orthographic projection of the fourth hollow region U4 on the substrate 101 may be located within the orthographic projection of the second hollow region U2 on the substrate 101. Here, the fourth hollow region U4 may communicate with the third hollow region U3 and the second hollow region U2. As shown in FIG5 , at least a portion of the touch leads 500 may pass through the fourth hollow region U4 and then be distributed within the third hollow region U3.

[0088] In this case, since the fourth hollow area U4 in the second planar layer 1024 is connected to the third hollow area U3 in the first planar layer 1023, and the orthographic projections of the third hollow area U3 and the fourth hollow area U4 on the substrate 101 are both located within the orthographic projection of the first hollow area U1 in the support layer 1021 on the substrate 101, and are both located within the orthographic projection of the second hollow area U2 in the pixel definition layer 1022 on the substrate 101, in the region of the driving backplate 100 where the third hollow area U3 and the fourth hollow area U4 are connected, the bearing groove U in the driving backplate 100 needs to simultaneously penetrate the supporting layer 1021, the pixel definition layer 1022, the second planar layer 1024, and the first planar layer 1023, thereby further reducing the thickness of the portion of the driving backplate 100 where the bearing groove U is provided, thereby further reducing the probability of the open mask being scratched into the third hollow area U3. In this way, it can be further ensured that the probability of the touch leads 500 subsequently distributed in the third hollow area U3 having adverse phenomena such as short circuit or disconnection is low.

[0089] In the embodiment of the present application, referring to FIG5 , the second planar layer 1024 in the driver backplane 100 may include a filling portion 1024a extending into the third hollow area U3. The orthographic projection of the touch leads 500 distributed within the third hollow area U3 on the substrate 101 may not overlap with the orthographic projection of the filling portion 1024a in the second planar layer 1024 on the substrate 101. In other words, the orthographic projection of the touch leads 500 distributed within the third hollow area U3 on the substrate 101 may be located within the orthographic projection of the fourth hollow area U4 in the second planar layer 1024 on the substrate 100.

[0090] In the present application, all of the multiple touch leads 500 in the display panel 000 can be distributed in the third hollow area U3, or only some of the touch leads 500 can be distributed in the third hollow area U3. To this end, the present application will use the following three implementation methods as examples for schematic description:

[0091] In a first implementation, as shown in FIG5 , all of the multiple touch leads 500 in the display panel 000 may be distributed in the third hollow area U3 .

[0092] In this case, since the fourth hollow area U4, the second hollow area U2 and the first hollow area U1 are distributed in sequence above the third hollow area U3, when the multiple touch leads 500 in the display panel 000 are all distributed in the third hollow area U3, it can be ensured that the thickness of the positions of these touch leads 500 are relatively low, and thus it can be ensured that the positions of these touch leads 500 are not easily scratched by the open mask plate, so that all the touch leads 500 distributed in the third hollow area U3 are not prone to adverse phenomena such as short circuit or breakage.

[0093] For a second implementation, see Figure 6, which illustrates another schematic diagram of the film layer structure within the non-display area of ​​a display panel provided in an embodiment of the present application. The multiple touch leads 500 in the display panel 000 may include: multiple first touch leads 501 distributed within the third hollowed-out area U3, and at least one second touch lead 502 distributed within the second planar layer 1024, with the filled portion 1024a facing away from the substrate 101.

[0094] It should be noted that, as can be seen from the foregoing, the first touch lead 501 located within the third hollow area U3 is less susceptible to defects such as short circuits or disconnections. Furthermore, for the at least one second touch lead 502 located on the side of the filled portion 1024a of the second flat layer 1024 facing away from the substrate 101, since the filled portion 1024a extends into the third hollow area U3 and is sequentially located above the filled portion 1024a, the overall thickness of the region of the driver backplane 100 where the filled portion 1024a is located is kept low. This makes it less likely for the open mask to scratch the filled portion 1024a, resulting in improved flatness of the filled portion 1024a. Consequently, the probability of defects such as short circuits or disconnections occurring on the second touch lead 502 located on the side of the filled portion 1024a facing away from the substrate 101 is reduced.

[0095] For a third implementation, please refer to FIG7 , which is a schematic diagram of a film layer structure in a non-display area of ​​another display panel provided in an embodiment of the present application. The multiple touch leads 500 in the display panel 000 may further include: multiple first touch leads 501 distributed in the first hollow area U1, and a third touch lead 503, wherein a portion of the third touch lead 503 may be located in the third hollow area U3, and another portion of the third touch lead 503 may be located on the side of the filled portion 1024a in the second flat layer 1024 facing away from the substrate 101. It should be noted that, based on the foregoing, the first touch leads 501 distributed in the third hollow area U3 are less likely to suffer from adverse phenomena such as short circuits or disconnections, and the third touch lead 503, which is partially located in the third hollow area U3 and another portion located on the side of the filled portion 1024a facing away from the substrate 101, is also less likely to suffer from adverse phenomena such as short circuits or disconnections.

[0096] The above embodiments are all schematically illustrated by taking the example of the driving backplane 100 containing two flat layers. Here, when the driving backplane 100 contains two flat layers, the two flat layers are the first flat layer 1023 and the second flat layer 1024, and such driving backplane 100 contains two source-drain conductive layers, wherein the first flat layer 1023 can cover the source-drain conductive layer closer to the substrate 101 of the two source-drain conductive layers, and the second flat layer 1024 can cover the source-drain conductive layer farther away from the substrate 101 of the two source-drain conductive layers. In other possible implementations, the driving backplane 100 can include three source-drain conductive layers, and these three source-drain conductive layers need to be covered by three flat layers respectively. To this end, please refer to Figure 8, which is a schematic diagram of the film layer structure of another display panel in the non-display area provided in an embodiment of the present application. The plurality of stacked organic layers 102 in the display panel 000 may further include a third planarization layer 1025 located between the second planarization layer 1024 and the pixel definition layer 1022 .

[0097] The bearing groove U in the driver backplane 100 may further include: a fifth hollow area U5 distributed within the third flat layer 1025. The orthographic projections of the third hollow area U3 and the fourth hollow area U4 on the substrate 101 may both be located within the orthographic projection of the fifth hollow area U5 on the substrate 101, and the orthographic projection of the fifth hollow area U5 on the substrate 101 may be located within the orthographic projection of the second hollow area U2 on the substrate 101. Here, the side of the fifth hollow area U5 facing the substrate 101 may be connected to the fourth hollow area U4, and the side of the fifth hollow area U5 facing away from the substrate 101 may be connected to the second hollow area U2.

[0098] It should be noted that by setting the fifth hollow area U5 in the third flat layer 1025, and allowing the orthographic projections of the third hollow area U3 and the fourth hollow area U4 on the substrate 101 to be located within the orthographic projection of the fifth hollow area U5 on the substrate 101, and at the same time allowing the orthographic projection of the fifth hollow area U5 on the substrate 101 to be located within the orthographic projection of the second hollow area U2 on the substrate 101, it can be ensured that the third flat layer 1025 set in the driving backplane 100 does not affect the normal distribution of the multiple touch leads 500 in the display panel 000.

[0099] In the embodiment of the present application, when the driving backplane 100 in the display panel 000 includes: a first planar layer 1023, a second planar layer 1024, a third planar layer 1025, a pixel definition layer 1022, and a support layer 1021, there are various ways to distribute the multiple touch leads 500 in the display panel 000. The embodiment of the present application will be described using the following five cases as examples:

[0100] In the first case, all of the touch leads 500 in the display panel 000 may be distributed in the third hollow area U3. Detailed descriptions can be found in the above content and will not be repeated here.

[0101] In the second case, the second flat layer 1024 in the driving backplane 100 may include a filling portion 1024a extending into the third hollow area U3. The multiple touch leads 500 in the display panel 000 may include a plurality of first touch leads 501 distributed within the third hollow area U3, and at least one second touch lead 502 distributed on a side of the filling portion 1024a in the second flat layer 1024 facing away from the substrate 101. The details are described above and are not repeated here.

[0102] In the third scenario, the second planar layer 1024 in the driver backplane 100 may include a filled portion 1024a extending into the third hollow region U3. The multiple touch leads 500 in the display panel 000 may include a plurality of first touch leads 501 distributed within the first hollow region U1, and a third touch lead 503. A portion of the third touch lead 503 may be located within the third hollow region U3, while another portion of the third touch lead 503 may be located on a side of the second planar layer 1024 facing away from the substrate 101. For details, please refer to the previous section and will not be repeated here.

[0103] For the fourth scenario, please refer to Figure 9, which is a schematic diagram of the film layer structure within the non-display area of ​​a display panel provided by another embodiment of the present application. The second planar layer 1024 in the driver backplane 100 may include a filling portion 1024a extending into the third hollow area U3, and a connecting portion 1024b connected to the filling portion 1024a. The orthographic projection of the connecting portion 1024b in the second planar layer 1024 on the substrate 101 may be located within the orthographic projection of the fifth hollow area U5 on the substrate 101. The multiple touch leads 500 in the display panel 000 may include a plurality of first touch leads 501 distributed within the third hollow area U3, at least one second touch lead 502 distributed in the second planar layer 1024 on a side of the filling portion 1024a facing away from the substrate 101, and at least one fourth touch lead 504 distributed in the second planar layer 1024 on a side of the connecting portion 1024b facing away from the substrate 101.

[0104] It should be noted that, as described above, the first touch lead 501 located within the third hollow area U3 and the second touch lead 502 located on the side of the filled portion 1024a facing away from the substrate 101 are both less susceptible to short circuits or disconnections. Furthermore, for the at least one fourth touch lead 504 located within the second planar layer 1024, whose connecting portion 1024b faces away from the substrate 101, the orthographic projection of the connecting portion 1024b on the substrate 101 can lie within the orthographic projection of the fifth hollow area U5 on the substrate 101. Consequently, the fifth hollow area U5, the second hollow area U2, and the first hollow area U1 are sequentially located above the connecting portion 1024b. This ensures that the overall thickness of the region of the driver backplane 100 where the connecting portion 1024b is located is relatively low, making it less likely for the open mask to scratch the connecting portion 1024b, thereby improving the flatness of the connecting portion 1024b. Therefore, it can be ensured that the probability of the fourth touch wire 504 distributed on the side of the connecting portion 1024b away from the substrate 101 having defects such as short circuit or disconnection is low.

[0105] For the fifth scenario, please refer to Figure 10, which is a schematic diagram of the film layer structure in the non-display area of ​​another display panel provided in another embodiment of the present application. Based on the fourth scenario described above, the multiple touch leads 500 in the display panel 000 may further include: a fifth touch lead 505 located between at least one fourth touch lead 504 and at least one second touch lead 502, and a sixth touch lead 506. Here, a portion of the fifth touch lead 505 may be located on the side of the filling portion 1024a of the second planar layer 1024 facing away from the substrate 101, and another portion of the fifth touch lead 505 may be located on the side of the connecting portion 1024b of the second planar layer 1024 facing away from the substrate 101. A portion of the sixth touch lead 506 may be located on the side of the connecting portion 1024b of the second planar layer 1024 facing away from the substrate 101, and another portion of the sixth touch lead 506 may extend outside the fifth hollow area U5. It should be noted that, according to the above content, the fifth touch lead 505 and the sixth touch lead 506 are also not prone to short circuit, disconnection or other adverse phenomena.

[0106] In the present application, the first retaining wall 601 and the second retaining wall 602 in the display panel 000 can be formed by stacking at least two organic layers 102 in the driving backplane 100. For example, the first retaining wall 601 and the second retaining wall 602 each include: a portion located in the first planar layer 1023, a portion located in the second planar layer 1024, a portion located in the third planar layer 1025, and a portion located in the pixel definition layer 1022.

[0107] In an embodiment of the present application, as shown in Figures 11 and 12, Figure 11 is another partial enlarged view of the display panel shown in Figure 1 at C, and Figure 12 is a schematic diagram of the cross-sectional structure of the display panel shown in Figure 11 at D-D'. The display panel 000 may further include an auxiliary support column 800 located between two adjacent touch leads 500.

[0108] In this case, by setting an auxiliary support column 800 between two adjacent touch leads 500, it can be ensured that in the process of depositing a thin film on the driving backplane 100 using an open mask plate to form the encapsulation layer 300, the open mask plate will only scratch the auxiliary support column 800, and will not scratch the areas on both sides of the auxiliary support column 800, thereby further improving the flatness of the areas on both sides of the auxiliary support column 800 in the driving backplane 100, so as to further reduce the probability of adverse phenomena such as short circuit or breakage of the touch leads 500 set on both sides of the auxiliary support column 800.

[0109] Optionally, the auxiliary support pillars 800 in the display panel 000 can be provided in the same layer and made of the same material as the support layer 1021 in the display panel 000. In other words, the auxiliary support pillars 800 and the support layer 1021 are formed by the same patterning process. The single patterning process may include: photoresist coating, exposure, development, etching, and photoresist stripping.

[0110] It should be noted that FIG12 is illustrated using the example of all touch leads 500 in the display panel 000 being distributed within the third hollow area U3. In this case, all auxiliary support pillars 800 in the display panel 000 may also be distributed within the third hollow area U3. In other possible implementations, as shown in FIG13, which is another schematic cross-sectional structure diagram of the display panel shown in FIG11 at the D-D' position, in the case where the multiple touch leads 500 in the display panel 000 include: a first touch lead 501 distributed within the third hollow area U3, and a second touch lead 502 distributed in the second flat layer 1024 with the filling portion 1024a facing away from the substrate 101, a portion of the auxiliary support pillars 800 in the display panel 000 may be located within the third hollow area U3, while another portion of the auxiliary support pillars 800 may be located on the side of the filling portion 1024a facing away from the substrate 101. Here, for the auxiliary support column 800 located in the third hollow area U3, the auxiliary support column 800 can be distributed between two adjacent first touch leads 501; for the auxiliary support column 800 located on the side of the filling part 1024a away from the substrate 101, the auxiliary support column 800 can be located between two adjacent second touch leads 502, or between the adjacently distributed first touch lead 501 and the second touch lead 502.

[0111] In an embodiment of the present application, referring to FIG14 , which is another partially enlarged view of the display panel at position C shown in FIG1 , the display panel 000 may further include: a plurality of transfer leads 700 electrically connected to the plurality of touch leads 500 in a one-to-one correspondence. Here, the extension direction of the transfer leads 700 may intersect the extension direction of the touch leads 500. For example, the extension direction of the transfer leads 700 may be perpendicular to the extension direction of the touch leads 500.

[0112] In the present application, the touch leads 500 and the transfer leads 700 in the display panel 000 can be provided in the same layer and made of the same material. That is, the touch leads 500 and the transfer leads 700 are formed through the same patterning process. This single patterning process may include: photoresist coating, exposure, development, etching, and photoresist stripping. Here, the touch leads 500 and the transfer leads 700 can both be provided in the same layer and made of the same material as the touch electrode layer 400 in the display panel 000.

[0113] At least a portion of the transfer leads 700 may be located on a side of the third planar layer 1025 facing away from the substrate 101 , and the transfer leads 700 may be distributed in the second hollow area U2 .

[0114] In this case, because the thickness of the portion of the driver backplane 100 where the second hollow area U2 is located is relatively small, the probability of the open mask scratching the portion of the driver backplane 100 where the second hollow area U2 is located is relatively low during the subsequent deposition of a thin film on the driver backplane 100 using an open mask to form the encapsulation layer 300. This ensures that the portion of the driver backplane 100 where the second hollow area U2 is located has good flatness. Therefore, it is possible to ensure that the transfer leads 700 located within the second hollow area U2 are less likely to suffer from defects such as short circuits or disconnections.

[0115] In the present application, the display panel 000 may further include: a plurality of first connection traces 900 electrically connected in a one-to-one correspondence with the plurality of transfer leads 700. Here, at least a portion of the first connection traces 900 may be located within the bending region 00c, and the first connection traces 900 may be provided on a different layer from the transfer leads 700. One end of the transfer lead 700 may be electrically connected in a one-to-one correspondence with the first connection traces 900, and the other end of the transfer lead 700 may be electrically connected in a one-to-one correspondence with the touch lead 500.

[0116] The first connecting trace 900 in the display panel 000 can be distributed between the second flat layer 1024 and the third flat layer 1025 in the driving backplane 100, or the first connecting trace 900 can be distributed between the second flat layer 1024 and the first flat layer 1023 in the driving backplane 100, or the first connecting trace can be distributed on the side of the first flat layer 1023 in the driving backplane 100 facing the substrate 101. In other words, the first connecting trace 900 in the display panel 000 is part of the source and drain conductive layer. It should be noted that at least one of the first flat layer 1023, the second flat layer 1024, and the third flat layer 1025 has a lap via, and the first connecting trace 900 can be electrically connected to the transfer lead 700 through the lap via.

[0117] Optionally, the display panel 000 may further include: a plurality of second connection traces electrically connected to the plurality of touch leads 500 in a one-to-one correspondence. Here, the second connection traces may be provided in the same layer and made of the same material as the touch leads 500. The ends of the second connection traces facing away from the touch leads 500 are used to electrically connect to the touch electrode layer 400 in the display panel 000.

[0118] In the present application, the end of the first connecting wire 900 in the display panel 000 that faces away from the adapter lead 700 is used to connect to the control component bound to the display panel 000. In this way, the control component can be electrically connected to the touch electrode layer 400 in the display panel 000 through the first connecting wire 900, the adapter lead 700, the touch lead 500, and the second connecting wire in sequence, thereby ensuring that the control component can obtain the touch position when the user touches the display panel 000 based on the touch electrode layer 400.

[0119] In an embodiment of the present application, as shown in FIG13 , when the driving backplane 100 includes a plurality of stacked organic layers 102 , at least a portion of the organic layers 102 may include a bending portion 102 a disposed in the bending region 00 c.

[0120] Optionally, when the plurality of stacked organic layers 102 in the driving backplane 100 include: a first flat layer 1023, a second flat layer 1024, a third flat layer 1025, a pixel definition layer 1022, and a support layer 1021, the first flat layer 1023, the second flat layer 1024, the pixel definition layer 1022, and the support layer 1021 may each include a bending portion 102a disposed within the bending region 00c. Here, the bending portion 102a disposed in the first flat layer 1023 and the second flat layer 1024 may extend outside the bending region 00c, and the bending portions 102a disposed in the pixel definition layer 1022 and the support layer 1021 may also extend outside the bending region 00c. Alternatively, the bending portions 102a disposed in the pixel definition layer 1022 and the support layer 1021 may all be located within the bending region 00c and not extend outside the bending region 00c. This embodiment of the present application is not limited thereto. There are many ways to configure the third flat layer 1025 in the driving backplane 100. This application will use the following two cases as examples for illustration:

[0121] The first possible scenario is shown in Figure 15, which is a schematic diagram of the film layer structure within the non-display area of ​​another display panel provided by another embodiment of the present application. The third planar layer 1025 in the driver backplane 100 may have an auxiliary hollow region K disposed within the bend region 00c. Here, the hollow region within the organic layer 102 refers to the structure obtained by removing at least a portion of the third planar layer 1025 located within the bend region 00c.

[0122] In a second possible scenario, as shown in FIG13 , the third flat layer 1025 in the driver backplane 100 may include a bend 102a disposed within the bend region 00c. In this case, each organic layer 102 in the driver backplane 100 includes a bend 102a disposed within the bend region 00c. This ensures that the overall thickness of the portion of the driver backplane 100 within the bend region 00c is relatively thick, thereby ensuring a significant difference in thickness between the portion of the driver backplane 100 within the bend region 00c and the portion of the driver backplane 100 where the bearing groove U is disposed. This further reduces the probability of the open mask plate scraping against the portion of the driver backplane 100 where the bearing groove U is disposed, thereby lowering the probability of short circuits or disconnections in the touch leads 500 distributed within the bearing groove U.

[0123] Please refer to Figure 16, which is a schematic diagram of the film layer structure within the display area of ​​a display panel provided in an embodiment of the present application. The driving backplane 100 in the display panel 000 may include: a substrate 101, and a buffer layer 103, an active layer 104, a first gate insulating layer 105, a first gate layer 106, a second gate insulating layer 107, a second gate layer 108, an interlayer dielectric layer 109, a first source and drain layer 110, a first planarizing layer 1023, a second source and drain layer 111, a second planarizing layer 1024, a third source and drain layer 112, a third planarizing layer 1025, an anode layer 201, a pixel definition layer 1022, and a support layer 1021.

[0124] The active layer 104, the first gate layer 106, the second gate layer 108, the first source-drain electrode layer 110, the second source-drain electrode layer 111, and the third source-drain electrode layer 112 are used to form a pixel driving circuit electrically connected to the light-emitting device 200, as well as various signal lines electrically connected to the pixel driving circuit. The light-emitting device 200 includes: an anode layer 201, a light-emitting layer 202, and a cathode layer 203 arranged in a stacked manner. The pixel driving circuit can be electrically connected to the anode layer 201 in the light-emitting device 200.

[0125] In the present application, at least one of the first source-drain electrode layer 110 , the second source-drain electrode layer 111 , and the third source-drain electrode layer 112 includes the first connecting trace 900 in the above embodiment.

[0126] In summary, the display panel provided by the embodiment of the present application includes: a driving backplane, an encapsulation layer, a touch electrode layer, a plurality of touch leads and a plurality of light-emitting devices. Since the overall thickness of the portion of the driving backplane where the bearing groove is set is relatively small. Therefore, in the process of depositing a thin film on the driving backplane using an open mask plate to form the encapsulation layer, the probability of the open mask plate scratching the portion of the driving backplane where the bearing groove is set is low, thereby ensuring that the flatness of the portion of the driving backplane where the bearing groove is set is better. For this reason, when the touch leads are subsequently formed in the non-display area of ​​the display panel, these touch leads can be distributed in the bearing groove to ensure that these touch leads can be distributed on the area with better flatness in the driving backplane, thereby ensuring that these touch leads are not prone to adverse phenomena such as short circuits or disconnections, making this display panel more reliable.

[0127] Embodiments of the present application also provide a display device. This display device can be any product or component with a display function, such as a mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, or navigation system. The display device can include a power supply assembly and a display panel electrically connected to the power supply assembly. The display panel can be the display panel described in the above embodiments.
