[0034] 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.

[0035] Please refer to Figure 1 and Figure 2 , Figure 1 is a top view of a display panel provided in an embodiment of the present application, Figure 2 yes Figure 1 The display panel 000 is shown in a cross-sectional view taken along line AA'. The display panel 000 may include a substrate 100, a multi-layer insulating functional layer 200, and a plurality of light-emitting devices (not shown). The display panel 000 may include a display area 00a and a frame area 00b located outside the display area 00a.

[0036] The multiple insulating functional layers 200 in the display panel 000 may be stacked on one side of the base substrate 100 , and a portion of the insulating functional layer 200 may be located in the display area 00 a , and another portion may be located in the frame area 00 b .

[0037] In one possible implementation, the multilayer insulating functional layer 200 may include: a buffer layer, a first gate insulating layer, a second gate insulating layer, and an interlayer insulating layer stacked in a direction perpendicular to and away from the base substrate 100. It should be noted that the individual insulating functional layers 200 in the display panel 000 are not described here; these insulating functional layers 200 will be described exemplarily in subsequent embodiments. It should also be noted that these insulating functional layers 200 are used to insulate adjacent conductive layers in the display panel 000, and these insulating functional layers 200 and the conductive layers may constitute the drive backplane in the display panel 000.

[0038] The multiple light-emitting devices in the display panel 000 can be located on a side of the multi-layer insulating functional layer 200 facing away from the base substrate 100, and the multiple light-emitting devices can be located in the display area 00a. Here, each light-emitting device can be an OLED light-emitting device, and the multiple light-emitting devices can be electrically connected to a driving backplane in the display panel 000. The driving backplane can drive the multiple light-emitting devices to emit light, so that the display panel 000 can display the corresponding image.

[0039] In the present application, the multi-layer insulating functional layer 200 may have at least one blocking groove 201 on a side facing away from the base substrate 100 . The at least one blocking groove 201 may be distributed in the frame area 00 b , and the blocking groove 201 may extend along a wavy line.

[0040] It should be noted that during the production of the display panel 000, a multi-layer thin film structure can be first formed on a substrate. After each layer of the thin film structure is formed on the substrate, the substrate can be cut to obtain multiple display panels. However, during the substrate cutting process, cracks are very likely to form in the border region 00b of the display panel 000, and the cracks are likely to extend laterally from the border region 00b of the display panel 000 toward the display region 00a of the display panel 000.

[0041] To this end, in the present application, since the side of the multi-layer insulating functional layer 200 facing away from the base substrate 100 can have at least one blocking groove 201, these blocking grooves 201 can be evenly distributed in the frame area 00b. Therefore, even if the frame area 00b of the display panel 000 is subjected to a force and cracks are generated, the extension path of the crack extending toward the display area 00a can be blocked by the blocking groove 201. Furthermore, since the blocking groove 201 set in the frame area 00b can extend along a wavy line, the blocking groove 201 extending along the wavy line can better disrupt the extension path of the crack extending toward the display area 00a. Therefore, the probability of the crack extending laterally from the blocking groove 201 to the display area 00a can be effectively reduced, thereby improving the reliability of the display panel 000.

[0042] In summary, the embodiment of the present application provides a display panel, comprising: a base substrate, a multi-layer insulating functional layer, and a plurality of light-emitting devices. Since the multi-layer insulating functional layer may have at least one blocking groove on the side facing away from the base substrate, these blocking grooves may be evenly distributed within the frame area. Therefore, even if the frame area of the display panel is subjected to a force and cracks are generated, the extension path of the cracks extending toward the display area can be blocked by the blocking grooves. Furthermore, since the blocking grooves provided in the frame area can extend along a wavy line, the blocking grooves extending along the wavy line can better disrupt the extension path of the cracks extending toward the display area. Therefore, the probability of the cracks extending laterally from the blocking groove to the display area can be effectively reduced, thereby improving the reliability of the display panel.

[0043] In the examples of this application, please refer to Figure 3 , Figure 3 2 is a top view of another display panel provided by an embodiment of the present application. The number of blocking grooves 201 can be multiple, and the multiple blocking grooves 201 can be arranged in sequence along the direction toward the display area 00a.

[0044] It should be noted that after the border area 00b of the display panel 000 is subjected to force and cracks are generated, the cracks will first pass through the blocking groove 201 among the multiple blocking grooves 201 that is away from the display area 00a of the display panel 000. The blocking groove 201 can disrupt the extension path of the cracks extending horizontally toward the display area 00a.

[0045] For example, let's assume that a crack originating in the border region 00b of the display panel 000 propagates to point A of a blocking groove 201 located farther from the display region 00a of the display panel 000. Subsequently, this wavy blocking groove 201 disrupts the propagation path of the crack extending laterally toward the display region 00a, allowing the crack to extend to point B of the next blocking groove 201. Because point A and point B are relatively far apart, the probability of the crack continuing from point B into the display region 00a is low, thereby improving the reliability of the display panel 000.

[0046] In this application, please refer to Figure 4 , Figure 4 2 is a schematic diagram of the structure of a blocking groove provided in an embodiment of the present application. The blocking groove 201 in the insulating functional layer 200 may include: a plurality of sequentially connected arc-shaped extension grooves 201a. Within a single blocking groove 201, at least some of the arc-shaped extension grooves 201a may have the same curvature. For example, within a single blocking groove 201, each arc-shaped extension groove 201a may have the same curvature.

[0047] It should be noted that, for any two different blocking grooves 201, the curvature of the arc-shaped extension groove 201a in one blocking groove 201 may be the same as the curvature of the arc-shaped extension groove 201a in the other blocking groove 201, or the curvature of the arc-shaped extension groove 201a in one blocking groove 201 may be different from the curvature of the arc-shaped extension groove 201a in the other blocking groove 201. To this end, the present application will use the following two optional implementations as examples for schematic description.

[0048] For the first optional implementation, please refer to Figure 5 , Figure 5 2 is a schematic diagram of another type of blocking groove structure provided by an embodiment of the present application. In any two different blocking grooves 201, if the curvature of the arc-shaped extension groove 201a in one blocking groove 201 is different from the curvature of the arc-shaped extension groove 201a in the other blocking groove 201, the curvature of the arc-shaped extension groove 201a in the plurality of blocking grooves 201 gradually decreases in the direction toward the display area 00a.

[0049] That is, the curvature of the arc-shaped extension groove 201a in the blocking groove 201 closest to the display area 00a of the display panel 000 among the multiple blocking grooves 201 is the smallest, and the curvature of the arc-shaped extension groove 201a in the blocking groove 201 farthest from the display area 00a of the display panel 000 among the multiple blocking grooves 201 is the largest, and for the blocking groove 201 distributed between these two blocking grooves 201 among the multiple blocking grooves 201, the curvature of the extension groove 201a in the blocking groove 201 is between the curvatures of the extension grooves 201a in the two blocking grooves 201.

[0050] Thus, when a force is applied to the border region 00b of the display panel 000 and a crack is generated, the crack will first pass through the blocking groove 201 having the largest curvature of the arc-shaped extension groove 201a. In this case, the blocking groove 201 is more effective in disrupting the extension path of the crack extending toward the display region 00a, thereby ensuring that the probability of the crack extending laterally from the blocking groove 201 to the display region 00a is low.

[0051] The second optional implementation method is Figure 4 As shown, in any two different blocking grooves 201, if the curvature of the arc-shaped extension groove 201a in one blocking groove 201 is the same as the curvature of the arc-shaped extension groove 201a in the other blocking groove 201, for the two adjacent blocking grooves 201, the arc-shaped extension groove 201a in one blocking groove 201 can extend into the area enclosed by the arc-shaped extension groove 201a in the other blocking groove 201. In this way, the distance between the two adjacent blocking grooves 201 in the direction toward the display area 00a of the display panel 000 can be reduced, thereby effectively reducing the border width of the display device.

[0052] In the examples of this application, please refer to Figure 6 , Figure 6 2 is a top view of another display panel provided by an embodiment of the present application. For a single blocking groove 201, the blocking groove 201 may include: a first blocking groove 2011 and a second blocking groove 2012 disposed opposite each other in a first direction A1; and a third blocking groove 2013 for connecting the first blocking groove 2011 and the second blocking groove 2012. The ends of the third blocking groove 2013 may be connected to the ends of the first blocking groove 2011 and the second blocking groove 2012, respectively. In other words, the first blocking groove 2011 and the second blocking groove 2012 may be connected via the third blocking groove 2013.

[0053] Here, the border region 00b of the display panel 000 may include a binding region 00c, which may be disposed opposite the third blocking groove 2013 in the second direction A2 and may be used to bind and connect with a driver component. For example, the binding region 00c may be used to bind and connect with a driver chip in the display device.

[0054] It should be noted that the blocking groove 201 is not provided in the binding area 00c of the frame area 00b of the display panel 000, but the blocking groove 201 can be provided in all areas of the frame area 00b except the binding area 00c. This ensures that the blocking groove 201 does not affect the normal operation of the driving components in the binding area 00c, and can more effectively reduce the probability of cracks extending laterally from the blocking groove 201 to the display area 00a, thereby further improving the reliability of the display panel 000.

[0055] Optionally, the first blocking groove 2011 and the second blocking groove 2012 in the blocking groove 201 may extend in a direction parallel to the second direction A2, and the third blocking groove 2013 may extend in a direction parallel to the first direction A1. The second direction A2 may intersect with the first direction A1, for example, the second direction A2 may be perpendicular to the first direction A1.

[0056] In the examples of this application, please refer to Figure 7 , Figure 7 This is a schematic diagram of the film layer structure within the border region of a display panel provided in an embodiment of the present application. The display panel 000 may further include an organic protective portion 300 located on the side of the multi-layer insulating functional layer 200 facing away from the base substrate 100. The organic protective portion 300 may be located within the border region 00b, and at least a portion of the organic protective portion 300 may extend into the blocking groove 201.

[0057] In this case, even if a blocking groove 201 is provided in the border area 00b of the display panel 000, it can be ensured that the portion of the border area 00b where the blocking groove 201 is provided is not easily deformed by the organic protective portion 300 extending into the blocking groove 201, thereby enhancing the strength of the border area 00b in the display panel 000, and further ensuring that the blocking groove 201 does not affect the overall strength of the display panel 000.

[0058] In this application, if Figure 7As shown, the display panel 000 may further include at least one retaining wall 400 located within the border area 00b and surrounding the display area 00a. The at least one retaining wall 400 in the display panel 000 may include a first retaining wall 401 and a second retaining wall 402. The first retaining wall 401 may be closer to the display area 00a than the second retaining wall 402. In other words, the first retaining wall 401 may surround the display area 00a, and the second retaining wall 402 may surround the first retaining wall 401.

[0059] The retaining wall 400 can be provided on the same layer and made of the same material as the organic protective portion 300. In other words, the retaining wall 400 and the organic protective portion 300 can be formed simultaneously through a single patterning process. Here, a single patterning process includes photoresist coating, exposure, development, etching, and photoresist stripping. This effectively simplifies the manufacturing process of the display panel 000 and reduces its manufacturing cost.

[0060] In the examples of this application, please refer to Figure 7 The display panel 000 may further include an encapsulation structure 500. The encapsulation structure 500 in the display panel 000 may be located on a side of the multi-layer insulating functional layer 200 facing away from the base substrate 100. Here, the encapsulation structure 500 may include a first inorganic encapsulation layer 501, an organic encapsulation layer 502, and a second inorganic encapsulation layer 503.

[0061] The first inorganic encapsulation layer 501 can be closer to the multi-layer insulating functional layer 200 than the second inorganic encapsulation layer 503, and the organic encapsulation layer 502 can be located between the first inorganic encapsulation layer 501 and the second inorganic encapsulation layer 503. Here, through the cooperation of the first inorganic encapsulation layer 501 and the second inorganic encapsulation layer 503 in the encapsulation structure 500, it can be used to encapsulate the light-emitting device to prevent water and oxygen in the external environment from corroding the light-emitting layer in the light-emitting device, thereby increasing the service life of the light-emitting device.

[0062] It should be noted that the organic encapsulation layer 502 located between the first inorganic encapsulation layer 501 and the second inorganic encapsulation layer 503 can be used to improve the flatness of the display side of the display panel 000, thereby ensuring that a protective cover can be installed on the display side of the display panel 000. However, the organic encapsulation layer 502 is very susceptible to absorbing water and oxygen from the external environment. To this end, it is necessary to block the organic encapsulation layer 502 by at least one retaining wall 400 in the above embodiment, so that the first inorganic encapsulation layer 501 and the second inorganic encapsulation layer 503 can wrap the edges of the organic encapsulation layer 502, thereby preventing water and oxygen from the external environment from invading the interior of the display panel 000 through the edges of the organic encapsulation layer 502.

[0063] In this application, please refer to Figure 7The base substrate 100 in the display panel 000 may include a first polyimide (PI) layer 100a, a first barrier layer 100b, and a second PI layer 100c stacked in a direction away from the base substrate 100. The first PI layer 100a and the second PI layer 100c may be used to improve the flexibility of the display panel 100; the first barrier layer 100b may be used to prevent external moisture and oxygen from entering the light-emitting devices of the display panel 100.

[0064] In the embodiments of this application, Figure 7 and Figure 8 As shown, Figure 8 Schematic diagram of the film layer structure within the display area of a display panel provided in an embodiment of the present application. Display panel 000 may include: a base substrate 100, and a buffer layer 201, an active layer 101, a first gate insulating layer 202, a first gate layer 102, a second gate insulating layer 203, a second gate layer 103, an interlayer dielectric layer 204, a first source-drain electrode layer 104, a first planarizing layer 105, a second source-drain electrode layer 106, a second planarizing layer 107, an anode layer 601, a pixel definition layer 108, and a support layer 109 stacked on one side of the base substrate 100.

[0065] The active layer 101, the first gate layer 102, the second gate layer 103, the first source-drain electrode layer 104, and the second source-drain electrode layer 106 are used to form a pixel driving circuit electrically connected to the light-emitting device, as well as various signal lines electrically connected to the pixel driving circuit. The light-emitting device 600 in the display panel 000 may include: an anode layer 601, a light-emitting layer 602, and a cathode layer 603 arranged in a stacked manner. The pixel driving circuit can be electrically connected to the anode layer 601 in the light-emitting device 600.

[0066] In the present application, at least one barrier rib 400 in the display panel 000 may be formed by stacking at least two organic layers in the display panel 000. For example, the barrier rib 400 may be formed by stacking a portion located in the first planar layer 105, a portion located in the second planar layer 107, and a portion located in the pixel definition layer 108.

[0067] In summary, the embodiment of the present application provides a display panel, comprising: a base substrate, a multi-layer insulating functional layer, and a plurality of light-emitting devices. Since the multi-layer insulating functional layer may have at least one blocking groove on the side facing away from the base substrate, these blocking grooves may be evenly distributed within the frame area. Therefore, even if the frame area of the display panel is subjected to a force and cracks are generated, the extension path of the cracks extending toward the display area can be blocked by the blocking grooves. Furthermore, since the blocking grooves provided in the frame area can extend along a wavy line, the blocking grooves extending along the wavy line can better disrupt the extension path of the cracks extending toward the display area. Therefore, the probability of the cracks extending laterally from the blocking groove to the display area can be effectively reduced, thereby improving the reliability of the display panel.

[0068] 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, advertising machine, display screen, or digital photo frame. 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, and the power supply assembly is used to supply power to the display panel.

[0069] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless expressly limited otherwise.

[0070] The above description is merely an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
