[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] With the continuous development of display technology, people have a higher demand for screen-to-body ratio. Taking mobile phone screens as an example, at present, the minimum width of the left and right borders of mobile phone screens is about 0.8mm, the minimum width of the upper border is about 0.65mm, and the minimum width of the lower border after bending is about 0.8mm. Since the left and right borders of the display screen contain driving circuits, packaging structures, wiring, and cutting path designs, it is difficult to further reduce the width of the borders.

[0024] To facilitate understanding of the structure of a conventional display panel, Figure 1 The structure shown is used as an example for explanation. Figure 1 Schematic diagram of the structure of a display panel in the related art. Figure 1As shown, the display panel includes a display area 110, a border area 120, and a binding area bent to the back of the display panel. The binding area is used to bind the chip 40 and / or the flexible circuit board 50. The border area 120 includes a dam 121 surrounding the display area 110. The border area 120 also includes a plurality of drive circuits (Gate in Panel, GIP) 122. The drive circuit 122 is located between the dam 121 and the display area 110. The drive circuit 122 is used to provide a scan signal to the scan signal line. Compared with setting the drive circuit 122 on the chip in the binding area, the drive circuit 122 is set in the extension direction of the scan signal line (that is, the border area 120 of the display panel). The connection can be achieved without too many wirings, saving the number of chips, reducing material costs and shortening the process time. Typically, the width of the drive circuit 122 is about 350um to 400um. Due to the existence of the drive circuit 122, the border width of the display panel cannot be further reduced, and it is difficult to achieve a nearly borderless structure. In addition, as Figure 1 As shown, when the display panel has an arc corner area, the driving circuit 122 is set in the left and right frames and the arc corner area of ​​the display panel. The frame of the display panel needs to be designed with sufficient width to accommodate the driving circuit 220 in the arc corner area, which further hinders the reduction of the frame width of the display panel.

[0025] In view of the above technical problems, an embodiment of the present application provides a display panel that can reduce the width of the border area of ​​the display panel and increase the screen-to-body ratio of the display panel. In an embodiment of the present application, the display panel includes a flexible display panel to facilitate bending of the display panel. The display panel includes a display area and a border area, the border area includes a non-bending area, the non-bending area is arranged around the display area, and the non-bending area includes a plurality of straight edge areas; a plurality of bending areas, any bending area corresponds to one of the plurality of straight edge areas, and the bending area is connected to the side of the straight edge area away from the display area; a circuit area is connected to the side of the bending area away from the display area; the bending area is in a bent state, and the circuit area is located on the non-display side of the display panel. In an embodiment of the present application, multiple bending areas are set in the border area, and a part of the border area of ​​the display panel (for example, the circuit area) is bent to the non-display side of the display panel, which can reduce the width of the border area of ​​the display panel; in addition, the part bent to the non-display side of the display panel has sufficient space to optimize the circuit design; in addition, the arc-shaped outer edge of the non-bending area is not connected to the bending area, which can avoid a large number of wrinkles caused by bending along the arc, thereby improving the reliability of the display panel.

[0026] Optionally, the display panel includes a substrate and a dam located on one side of the substrate, the dam is located in the non-bending area, and the dam surrounds the display area. By setting the dam, the packaging effect of the display panel can be improved, and the reliability of the display panel can be improved. In an embodiment of the present application, the substrate is a flexible substrate, for example, polyimide. Optionally, the non-bending area also includes an arc angle area connecting adjacent straight edge areas, and the display panel includes a plurality of conductive wires, at least part of which is located in the arc angle area. In some embodiments, the conductive wires in the arc angle area are located on the side of the dam close to the display area. In this way, the conductive wires do not occupy the area of ​​the arc angle area on the side of the dam away from the display area, which is conducive to reducing the width of the frame. In some embodiments, since the area of ​​the side of the dam close to the display area is small, if the number of conductive wires is large, some of the conductive wires in the arc angle area are located on the side of the dam close to the display area, and some of the conductive wires in the arc angle area are located on the side of the dam away from the display area. Optionally, in order to prevent the conductive wires from being corroded (especially the conductive wires located on the side of the dam away from the display area), the material of the conductive wires includes molybdenum, and specifically, the conductive wires are M1 metal wires or M2 metal wires in the array substrate.

[0027] In some embodiments, the manufacturing process of the display panel can realize independent packaging of pixel units, that is, each pixel unit is packaged separately. In this case, the dam can be omitted, so that the width of the border area of ​​the display panel can be further reduced while ensuring a good packaging effect.

[0028] Optionally, in some embodiments, the display panel includes a driving circuit, and the driving circuit is located in the circuit area. The display panel includes a plurality of scanning signal lines, and the scanning signal lines are connected to the driving circuit. Optionally, one end of the scanning signal line is connected to the driving circuit, or both ends of the scanning signal line are connected to the driving circuit. When both ends of the scanning signal line are connected to the driving circuit, the resistance and capacitance load on the scanning signal line can be reduced, and the display performance can be improved. Optionally, part of the scanning signal line is located in the bending area and the non-bending area, and part of the scanning signal line is wound along the outer edge of the arc angle area and extends to the display area. That is, in the arc angle area, the scanning signal line is connected to the driving circuit by fanning out. In an embodiment of the present application, the circuit area is set on the non-display side of the display panel. At this time, the size restriction of the circuit area is small, and there is sufficient space to optimize the circuit design, specifically, optimize the arrangement of the driving circuit, or optimize the size of the driving circuit, for example, the length of the driving circuit is lengthened and the height is compressed, so as to realize that all GIPs are placed on the side of the straight edge area of ​​the non-bending area away from the display area, and the scanning signal line is connected to the driving circuit located on the side of the straight edge area away from the display area by fanning out.

[0029] The technical solution of the present application is further described below through specific embodiments.

[0030] Figure 2 is a schematic diagram of the structure of a display panel provided by an embodiment of the present application. Figure 2As shown, the display panel 10 includes a display area 110 and a frame area. The frame area includes a non-bending area 210 and a plurality of bending areas. The non-bending area 210 surrounds the display area 110, and the non-bending area 210 includes a plurality of straight edge areas 211 and an arc angle area 212 connecting adjacent straight edge areas 211. Any bending area corresponds to one of the plurality of straight edge areas 211, and the bending area is connected to a side of the corresponding straight edge area 211 away from the display area. Figure 2 As shown, the non-bending area 210 includes four straight edge areas 211 and four arc angle areas 212. Figure 2 As shown, the number of bending zones is three, for example, the first bending zone 221, the second bending zone 222 and the third bending zone 223, the first bending zone 221 and the second bending zone 222 are respectively located at the first side and the second side opposite to the display area 110, and the third bending zone 223 is located at the third side of the display area 110. The three bending zones (i.e., the first bending zone 221, the second bending zone 222 and the third bending zone 223) are respectively connected to the side of the three straight edge zones 211 away from the display area 110, and a part of the frame area of ​​the display panel 10 is bent to the non-display side of the display panel 10, which can reduce the width of the frame area of ​​the display panel 10. In addition, the arc angle zone 212 is not connected to the bending zone, which can avoid the bending zone bending along the arc line to generate a large number of wrinkles, thereby improving the reliability of the display panel 10.

[0031] Continue to refer Figure 2 , the frame area also includes a circuit area, the circuit area is connected to the side of the bending area away from the display area 110; the bending area is in a bent state, and the circuit area is located on the non-display side of the display panel. In the embodiment of the present application, the circuit area includes a first circuit area 231 and a second circuit area 232, the first circuit area 231 is connected to the first bending area 221, and the second circuit area 232 is connected to the second bending area 222. The first circuit area 231 and the second circuit area 232 are located on the non-display side of the display panel 10. The first circuit area 231 includes a plurality of first drive circuits 2311, and the second circuit area 232 includes a plurality of second drive circuits 2321. It can be understood that "first" and "second" are only used for distinction, and the first drive circuit 2311 and the second drive circuit 2321 can be the same drive circuit. It should be noted that adjacent first drive circuits 2311 are connected by signal lines (not shown in the figure), so as to realize row-by-row drive of the scanning signal lines, and adjacent second drive circuits 2321 are connected by signal lines (not shown in the figure), so as to realize row-by-row drive of the scanning signal lines.

[0032] The display panel 10 includes a plurality of scanning signal lines 311, and the scanning signal lines 311 are connected to the driving circuit. In the embodiment of the present application, the first driving circuit 2311 and the second driving circuit 2321 correspond to each other. The first end of the scanning signal line 311 is connected to the first driving circuit 2311, and the second end of the scanning signal line 311 is connected to the second driving circuit 2321 corresponding to the first driving circuit 2311. Both ends of the scanning signal line 311 are connected to the driving circuit, which can reduce the resistance and capacitance load on the scanning signal line 311 and improve the display performance.

[0033] Continue to refer Figure 2 , part of the scanning signal line 311 is located in the arc angle area 212 of the non-bending area 210. The scanning signal line 311 located in the arc angle area 212 is wound along the outer edge of the arc angle area 212, extends through the first bending area 221 to the first circuit area 231 and is connected to the first driving circuit 2311, and / or extends through the second bending area 222 to the second circuit area 232 and is connected to the second driving circuit 2321. In the embodiment of the present application, the scanning signal line 311 located in the arc angle area 212 is connected to the first driving circuit 2311 located in the first circuit area 231 and / or the second driving circuit 2321 located in the second circuit area 232 in a fan-out manner, avoiding the need to set a driving circuit in the arc angle area, which is beneficial to reducing the area of ​​the arc angle area, and further reducing the width of the border area of ​​the display panel 10.

[0034] Continue to refer Figure 2 , the frame area also includes a binding area 233, which is connected to the third bending area 223 and is located on the non-display side of the display panel 10. The binding area 233 is used to bind the chip 40 or the flexible circuit board 50. The first drive circuit 2311 is connected to the chip 40 or the flexible circuit board 50 through the first conductive line 23111, and the second drive circuit 2321 is connected to the chip or the flexible circuit board 50 through the second conductive line 23211. Optionally, the chip 40 transmits high-level signals, low-level signals, clock signals, etc. to the first drive circuit 2311 and / or the second drive circuit 2321, so that the first drive circuit 2311 and / or the second drive circuit 2321 can output scan signals. For clear display, Figure 2 Only a part of the first conductive line 23111 and the second conductive line 23211 is shown. It can be understood that one end of the first conductive line 23111 is connected to the first driving circuit 2311, and the other end is connected to the chip 40; one end of the second conductive line 23211 is connected to the second driving circuit 2321, and the other end is connected to the chip 40. In addition, the first conductive line 23111 or the second conductive line 23211 includes a plurality of signal lines, which are respectively used to transmit high-level signals, low-level signals, clock signals, etc.

[0035] Continue to refer Figure 2The display panel 10 includes a substrate (not shown) and a dam 213 located on one side of the substrate, the dam 213 is located in the non-bending area 210, and the dam 213 surrounds the display area 110. In the embodiment of the present application, the substrate is a flexible substrate, for example, the material of the substrate includes polyimide. In the embodiment of the present application, the dam 213 is located between the bending area and the display area 110, close to the display area 110, which is conducive to reducing the width of the border area of ​​the display panel 10.

[0036] In the embodiment of the present application, at least part of the first conductive line 23111 and / or the second conductive line 23211 is located in the arc angle area 212, and the first conductive line 23111 and / or the second conductive line 23211 in the arc angle area 212 is located on the side of the dam 213 close to the display area 110. Such a configuration is conducive to reducing the width of the border area. Optionally, in order to prevent the first conductive line 23111 and / or the second conductive line 23211 from being corroded, the material of the first conductive line 23111 and / or the second conductive line 23211 includes molybdenum. Preferably, the first conductive line 23111 and / or the second conductive line 23211 is an M1 metal line or an M2 metal line in the array substrate.

[0037] Optionally, according to actual needs, the number of bending zones can also be two or four. For example, the number of bending zones is two, including the first bending zone 221 and the second bending zone 222, or including the first bending zone 221 and the third bending zone 223, or including the second bending zone 222 and the third bending zone 223. For another example, the number of bending zones is four, such as Figure 3 shown. Figure 3 The display panel 10 shown is Figure 2 The difference of the display panel 10 shown is that the display panel 10 further includes a fourth bending area 224, which is located at the fourth side of the display area 110, and the fourth side is arranged opposite to the third side. The display panel 10 further includes a third circuit area 234, which is connected to the fourth bending area 224. When the fourth bending area 224 is in a bent state, the third circuit area 234 is located at the non-display side of the display panel 10. By providing the fourth bending area 244 and the third circuit area 234, the display panel can be bent on four sides, and the width of the border area of ​​the display panel 10 can be further reduced.

[0038] exist Figure 2 or Figure 3In the embodiment shown, the two ends of each scanning signal line are respectively connected to the first driving circuit 2311 and the second driving circuit 2321, the first driving circuit 2311 is located in the first circuit area 231, and the second driving circuit 2321 is located in the second circuit area 232. The scanning signal lines located in the arc angle area 212 are connected to the first driving circuit 2311 and the second driving circuit 2321 by fan-out. If the arc angle radius of the display panel 10 is relatively large, multiple scanning signal lines need to be connected to the first driving circuit 2311 and / or the second driving circuit 2321 by fan-out in the arc angle area, resulting in a large number of scanning signal lines located in the arc angle area and requiring a longer winding to be connected to the first driving circuit 2311 or the second driving circuit 2321, thereby occupying a larger area, which is not conducive to reducing the width of the border area. At this time, part of the driving circuit can be designed in the third circuit area 234.

[0039] For example, Figure 4 1 is a schematic diagram of the structure of a display panel 10 provided in yet another embodiment of the present application. Figure 4 The display panel 10 shown is Figure 3 The difference of the display panel 10 shown is that the third circuit area 234 includes at least one third driving circuit 2341. At least one scanning signal line located in the arc angle area 212 is wound along the outer edge of the arc angle area 212, extends through the fourth bending area 224 to the third circuit area 234 and is connected to the third driving circuit 2341. In this way, part of the scanning signal line located in the arc angle area 212 is connected to the first driving circuit 2311 or the second driving circuit 2321, and part of the scanning signal line located in the arc angle area 212 is connected to the third driving circuit 2341, which shortens the winding length of the scanning signal line, which is conducive to further reducing the width of the border area of ​​the display panel 10. In the embodiment of the present application, the first circuit area 231, the second circuit area 232, the binding area 233 and the third circuit area 234 do not overlap in the direction perpendicular to the display area 110.

[0040] Since signal lines are required to connect adjacent drive circuits, continue to refer to Figure 4, the third driving circuit 2341 is connected to the first driving circuit 2311 through the third conductive line 23411, and / or the third driving circuit 2341 is connected to the second driving circuit 2321 through the fourth conductive line 23412. At least part of the third conductive line 23411 and the fourth conductive line 23412 are located in the arc angle area 212. Optionally, the third conductive line 23411 and the fourth conductive line 23412 of the arc angle area 212 are located on the side of the dam 213 close to the display area 110, so as to avoid setting the third conductive line 23411 and the fourth conductive line 23412 on the side of the dam 213 away from the display area 110, which is conducive to further reducing the width of the border area of ​​the display panel 10. Optionally, the material of the third conductive line 23411 and the fourth conductive line 23412 includes molybdenum. Preferably, the third conductive line 23411 and the fourth conductive line 23412 are M1 metal lines or M2 metal lines in the array substrate.

[0041] Figure 5 1 is a schematic diagram of the structure of a display panel 10 provided in yet another embodiment of the present application. Figure 5 The display panel 10 shown is Figure 2 The difference of the display panel 10 shown is that the display panel 10 does not include a dam. In the embodiment of the present application, the pixel units of the display panel 10 can be packaged independently without the need for full-surface packaging, so that the dam can be eliminated. Figure 5 It can be seen that the width of the border area of ​​the display panel 10 can be further reduced. In addition, in this embodiment, when the upper border is not bent, the width of the upper border can be compressed to less than 0.4 mm. Therefore, in this solution, only three sides need to be bent to achieve an extremely narrow border or a nearly borderless border.

[0042] Figure 6 1 is a schematic diagram of the structure of a display panel 10 provided in yet another embodiment of the present application. Figure 6 The display panel 10 shown includes Figure 2 The structure or components of the display panel 10 shown are shown for clarity. Figure 6 Part of the structure or components of the display panel 10, such as the first driving circuit 2311, the second driving circuit 2321, the scanning signal line 311, etc. are not shown. Figure 6As shown, the display panel 10 also includes a plurality of data signal lines 312, which are perpendicular to the scan signal lines 311 (not shown in the figure), and the data signal lines 312 extend from the display area 110 through the third bending area 223 to the binding area 233 and are connected to the chip 40 (only a portion of the data signal lines 312 is shown in the figure). In the embodiment of the present application, the third bending area 223 is connected to the side of the straight edge area 211 of the non-bending area 210 away from the display area 110. Compared with the bending area of ​​the conventional display panel 10, the connection length between the third bending area 223 and the display panel 10 is longer, and the data signal lines 312 and other signal lines (for example, the first conductive line 23111, the second conductive line 23211, etc.) have sufficient space for arrangement, and the data signal lines 312 do not need to fan out a large number of wires, and the width requirement of the third bending area 223 becomes lower, which is conducive to further shortening the width of the border area.

[0043] The embodiment of the present application provides a display device, which includes the display panel 10 described above.

[0044] Figure 7 is a schematic diagram of the structure of a display device provided by an embodiment of the present application. Figure 7 As shown, the display device 700 includes the display panel provided by any of the above embodiments.
