[0036] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present application and are not configured to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0038] It should be understood that when describing the structure of a component, when a layer or a region is referred to as being "on" or "over" another layer or another region, it may mean that it is directly on the other layer or another region, or that other layers or regions are included between it and the other layer or another region. Moreover, if the component is turned over, the layer or a region will be "below" or "beneath" another layer or another region.

[0039] In some display panels, in order to meet the needs of display and touch, a driving circuit, such as a gate driving circuit (Gate In Panel circuit, also known as GIP circuit) is provided inside the display panel. The driving circuit is arranged at the frame position of the display panel, and the driving circuit is electrically connected to the fan-out line, which is used to transmit the signal of the driving circuit to the display area, so as to meet the different functional needs of the display panel.

[0040] In the related art, GIP is set on the left and right borders as a driving circuit. In the straight edge area, the driving circuit and the display area can be directly connected horizontally, and the space required for the connection is relatively small. In the process of implementing the present invention, the inventors found that the following problems exist in the related art: for the arc angle area, an arc-shaped fan-out line wiring design is required from the driving circuit to the display area, which affects the realization of the narrow border of the product.

[0041] In order to solve the above problems, embodiments of the present application provide a display panel and a display device. Embodiments of the display panel and the display device will be described below in conjunction with the accompanying drawings.

[0042] An embodiment of the present application provides a display panel, which may be an organic light emitting diode (OLED) display panel.

[0043] See also Figures 1 to 4 , Figure 1 A schematic diagram of a top view structure of a display panel provided in an embodiment of the present application is shown; Figure 2 One of the partial enlarged views of the top view structure of a display panel provided in an embodiment of the present application is shown; Figure 3 A second partial enlarged view of a top view structure of a display panel provided in an embodiment of the present application is shown; Figure 4 A partial cross-sectional structure diagram of a display area of ​​a display panel provided in an embodiment of the present application is shown.

[0044] like Figures 1 to 4As shown, a first aspect of the present application provides a display panel, which includes a display area 10 and a frame area 20; the display area 10 includes a first display area 101 and a second display area 102, the second display area 102 is located on one side of the first display area 101 in a first direction X, and the frame area 20 is located on at least one side of the display area 10 in a second direction Y.

[0045] The display panel includes a substrate 1, a driving component 2, a first driving signal line 31 and a first driving connection line 41, wherein the driving component 2 is arranged on one side of the substrate 1 and is located in the frame area 20; the first driving signal line 31 extends along the second direction Y and extends from the first display area 101 to the frame area 20; the first driving connection line 41 is connected between the driving component 2 and the first driving signal line 31; wherein, along the second direction Y, the length of the first display area 101 is less than the length of the second display area 102, and the first driving connection line 41 is at least partially located in the second display area 102.

[0046] The substrate 1 may be a flexible substrate or a rigid substrate.

[0047] Optionally, the first direction X intersects with the second direction Y. Optionally, the first direction X and the second direction Y may be arranged perpendicularly.

[0048] Optionally, the frame area 20 may be located on at least one side of the display area 10 in the first direction X. To facilitate indicating the position of the frame area 20 , the frame area 20 located on one side of the display area 10 in the second direction Y is used as an example in this embodiment of the application.

[0049] Combined with reference Figure 1 and Figure 2 , the length of the first display area 101 is smaller than that of the second display area 102, and the first display area 101 or the second display area 102 may correspond to the arc angle area 30 of the display panel on both sides of the second direction Y; optionally, in the display area 10 opposite to the arc angle area 30 in the second direction Y, the length of the display area 10 in the second direction Y gradually increases from the direction from the first display area 101 to the second display area 102.

[0050] Optionally, the first display area 101 may correspond to a row of display pixels, and the second display area 102 may correspond to another row of display pixels. Optionally, the driving component 2 includes a plurality of driving units, and the driving unit may be a GIP circuit. Optionally, the first driving signal line 31 may be used as one of the light emitting control signal, the positive scanning signal line, and the negative scanning signal line of the first display area 101.

[0051] According to the display panel of the embodiment of the present application, the display panel includes a substrate 1, a driving component 2, a first driving signal line 31 and a first driving connecting line 41. The part of the first driving connecting line 41 connecting the driving component 2 and the first display area 101 is designed to be within the second display area 102, that is, it can be routed through the second display area 102 which is close to the first display area 101 and has a length greater than the first display area 101. The winding space of the first driving connecting line 41 in the border area 20 required from the driving component 2 to the first display area 101 can be effectively reduced, thereby reducing the area of ​​the border area 20 occupied by the first driving connecting line 41, thereby reducing the border ratio of the display panel, and improving the screen-to-body ratio and performance of the display panel.

[0052] The display panel provided by the embodiment of the present application is particularly suitable for the arc angle area 30 of the display panel. In the arc angle area, the length of the display area 10 is set to decrease, and in order to maintain reliable connection between the various driving units between the driving components 2, it is not suitable to change the position of the display area 10 to a large extent, that is, it is not convenient to always keep the distance between the corresponding sub-display area constant. As the length of the display area 10 decreases, the spacing between each sub-display area and the corresponding driving unit is gradually increased, so that in the arc angle area 30, if an arc-shaped fan-out line wiring design is adopted from the driving component 2 to the display area 10, a larger space is required for wiring. The present application arranges part of the driving connection line connecting the driving component 2 to the display area 10 in the display area 10, and can route from other sub-display areas close to the driving component 2 to the border area 20 and connect with the driving component 2, thereby reducing the area of ​​the border area 20 occupied by the driving connection line, thereby reducing the border ratio of the display panel, and improving the screen-to-body ratio and performance of the display panel.

[0053] Reference Figure 1 The display panel may have four arc angle areas 30. Corresponding to each arc angle area 30, the driving connection line portion connecting the driving component 2 and the sub-display area may be designed to be routed in one or more adjacent sub-display areas with reference to the solution provided in the embodiment of the present application, thereby reducing the winding space in the border area 20 required for the driving connection line, thereby reducing the border of the display panel and improving the screen-to-body ratio and performance of the display panel.

[0054] Reference Figure 2 In some optional embodiments, the display area 10 further includes a third display area 103 located on a side of the second display area 102 away from the first display area 101, and the length of the third display area 103 in the second direction Y is greater than the length of the second display area 102. Optionally, the display area 10 further includes a fourth display area 104 located on a side of the third display area 103 away from the second display area 102, and the length of the fourth display area 104 in the second direction Y is greater than the length of the third display area 103.

[0055] Exemplarily, the connection end of the first driving unit 21 corresponding to the first display area 101 is arranged close to the third display area 103 or the third display area 103 is arranged away from the fourth display area 104 of the first display area 101. Then, after entering the second display area 102, the first driving connection line 41 can be routed to the third display area 103 or the fourth display area 104, and re-enter the border area 20 from the third display area 103 or the fourth display area 104 and connect with the first driving unit 21.

[0056] In the same principle, in some optional embodiments, the display panel further includes a second drive signal line 32 and a second drive connection line 42, the second drive signal line 32 extends along the second direction Y and extends from the second display area 102 to the frame area 20, the second drive connection line 42 is connected between the drive component 2 and the second drive signal line 32, and the second drive connection line 42 is at least partially located in the third display area 103. As well as the third drive signal line, the third drive connection line, etc., these drive connection lines can be routed to the adjacent and longer sub-display area so that the drive connection line gradually approaches the drive unit to be connected, reducing the area of ​​the frame area 20 occupied by the drive connection line, and improving the screen ratio and performance of the display panel.

[0057] Optionally, the sub-display area closest to the first driving unit 21 is not separated from the first display area 101 by more than three rows of other sub-display areas, which is beneficial to reducing the routing path of the driving connection lines as a whole.

[0058] Optionally, the second display area 102 includes a protruding area 102a protruding toward the driving assembly 2 relative to the first display area 101, and the first driving connection line 41 is at least partially located in the protruding area 102a.

[0059] The length of the second display area 102 is greater than that of the first display area 101 . Both sides of the second display area 102 in the second direction Y may have protruding areas 102 a protruding relative to the first display area 101 .

[0060] In these embodiments, after the first drive connection line 41 is connected to the first drive signal line 31 at one end located in the border area 20, the line can be directly routed along the first direction X into the protruding area 102a, which is beneficial to reducing the routing length of the first drive connection line 41 and facilitating the horizontal and vertical array layout of the first drive connection line 41.

[0061] Optionally, the first driving connection line 41 includes a first connection segment 411 and a second connection segment 412 connected to each other, the first connection segment 411 extends along the first direction X and is connected to the first driving signal line 31, and the second connection segment 412 extends along the second direction Y. The first connection segment 411 can be used to route to different sub-display areas, and the second connection segment 412 extends within the same sub-display area, which is convenient for compatibility with the process in the display area 10 and has little impact on the film layer structure in the display area 10.

[0062] Reference Figure 2 and Figure 3 , for the convenience of distinction, Figure 2 and Figure 3 The dashed lines of different proportions indicate the first connecting section 411 and the second connecting section 412 located in different film layers, respectively. Figure 3 The black blocks indicate via holes. Optionally, in the thickness direction of the display panel, the first connection segment 411 and the second connection segment 412 are located in different film layers, and the first connection segment 411 and the second connection segment 412 are connected via via holes.

[0063] The first connection segment 411 and the second connection segment 412 are connected via a via hole, which is a channel connecting conductors on different layers, allowing current to flow from one layer to another layer, or realizing signal transmission between different layers. A conductive material is provided in the via hole to make the first connection segment 411 and the second connection segment 412 conductive.

[0064] The first connection segment 411 and the second connection segment 412 are located in different film layer structures, that is, the first connection segment 411 and the second connection segment 412 are located at different positions in the thickness direction of the display panel. This design is conducive to setting multiple metal conductive layers of the same layer as the first connection segment 411 along the second direction Y on the entire surface of the film layer where the first connection segment 411 is located, and is conducive to setting multiple metal conductive layers of the same layer as the second connection segment 412 along the first direction X on the entire surface of the film layer where the second connection segment 412 is located, so that the circuit structure in the display panel is more orderly and the structure is more compact. The longitudinal wiring extending along the first direction X and the transverse wiring extending along the second direction Y will not interfere with each other due to interlacing.

[0065] In some optional embodiments, there are multiple first driving signal lines 31 , and there are multiple first driving connection lines 41 , and each first driving signal line 31 and each first driving connection line 41 are provided correspondingly.

[0066] One driving unit can be connected to a plurality of first driving signal lines 31, and different first driving signal lines 31 can achieve different functions. For example, one first driving signal line 31 can be used as one of the light emitting control signal, the positive scanning signal line, and the negative scanning signal line of the first display area 101.

[0067] Reference Figure 2 For a layout in which one driving unit controls one sub-display area, each first driving signal line 31 and each first driving connecting line 41 are correspondingly arranged.

[0068] Reference Figure 3 For a layout in which one driving unit controls two or more sub-display areas, the first driving connection line 41 and the second driving connection line 42 can be reused in the portion located in the display area 10, thereby saving layout space.

[0070] In these embodiments, the connection position between the driving component 2 and the first driving connection line 41 is arranged closer to the second display area 102 relative to the first display area 101. The first driving connection line 41 is bent from one end of the first driving signal line 31 located in the border area 20 to enter the second display area 102, and is re-extended along the second direction Y from the second display area 102 and re-enters the border area 20 to connect with the driving component 2, thereby reducing the winding space in the border area 20 required for the first driving connection line 41 from the first driving signal line 31 to the driving component 2, thereby reducing the area of ​​the border area 20 occupied by the first driving connection line 41, and improving the screen-to-body ratio and performance of the display panel.

[0071] In some optional embodiments, the driving component 2 is at least located on one side of the third display area 103 in the second direction Y, and the first driving connection line 41 is connected to the driving component 2 from the first driving signal line 31 in sequence through the border area 20, the second display area 102, the third display area 103, and the border area 20.

[0072] In these embodiments, the connection position between the driving component 2 and the first driving connection line 41 is arranged closer to the third display area 103 relative to the first display area 101 and the second display area 102. The first driving connection line 41 is bent from one end of the first driving signal line 31 located in the border area 20 to enter the second display area 102. After entering the third display area 103 along the second display area 102, it is re-extended along the second direction Y from the third display area 103 and re-enters the border area 20 to connect with the driving component 2, thereby reducing the winding space of the first driving connection line 41 in the border area 20 required from the first driving signal line 31 to the driving component 2, thereby reducing the area of ​​the border area 20 occupied by the first driving connection line 41, and improving the screen-to-body ratio and performance of the display panel.

[0073] It can be understood that the display panel may further include a fourth display area 104, a fifth display area 105, etc. If the connection position between the driving component 2 and the first driving connection line 41 is closer to the fourth display area 104 or the fifth display area 105 than the aforementioned sub-display area, the first driving connection line 41 may also be routed to the fourth display area 104 or the fifth display area 105, and then re-enter the frame area 20 from the fourth display area 104 or the fifth display area 105 to connect with the driving component 2. This embodiment of the present application will not be described in detail.

[0074] Optionally, the driving assembly 2 includes a first driving unit 21 and a second driving unit 22, the first driving unit 21 is connected to the first driving connection line 41, and the second driving unit 22 is connected to the second driving connection line 42. For a layout in which one driving unit controls one sub-display area, each driving signal line, each driving connection line, and each driving unit can be set in a one-to-one correspondence.

[0075] Optionally, the first drive connection line 41 and the second drive connection line 42 are both connected to the first drive unit 21. Optionally, the first drive connection line 41 and the second drive connection line 42 are mutually reused in at least a portion located in the third display area 103. Optionally, the first drive connection line 41 and the second drive connection line 42 are mutually reused in at least a portion located in the fourth display area 104. For a layout in which one drive unit controls two or more sub-display areas, the first drive connection line 41 and the second drive connection line 42 can be mutually reused in the portion located in the display area 10, thereby saving layout space. Exemplarily, the portions of the drive connection lines extending along the second direction Y can be mutually reused, and a horizontal wiring can simultaneously connect two longitudinal wirings to transmit the same signal to sub-display areas located in different rows.

[0076] Combined with reference Figures 1 to 4 In some optional embodiments, the display panel also includes a driving circuit layer 11, a first insulating layer 12, a first conductive part 13, a second insulating layer 14, a second conductive part 15, a third insulating layer 16 and a light-emitting device 17, which are located in the display area 10 and are stacked in sequence in a direction away from the substrate 1.
