[0034] In order to better understand the technical solution of the present invention, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] It should be clear that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0037] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0038] Typically, at least one functional circuit is disposed in the border area of ​​the display panel. The functional circuit includes a plurality of circuit units with the same circuit structure. The circuit units are connected to signal lines in the display area to transmit driving signals required for display to the signal lines.

[0039] When the display panel is of a special-shaped design, in a related design, there is a certain angle bend between two adjacent panel edges in the display panel. The inventor found during the research process that in this type of display panel, the arrangement of the circuit units is not good, which will have an adverse effect on the display performance of the display panel.

[0040] For example, Figure 1 As shown, Figure 1 The present invention is a schematic diagram of a structure of a display panel in the related art, wherein the display panel includes a first panel edge 101 and a second panel edge 102 which are adjacently connected, and the first panel edge 101 and the second panel edge 102 extend in straight lines respectively and have a certain angle therebetween. Based on this structure, in the current design, when the circuit units 104 in the functional circuit 103 are arranged in the part of the frame area 105 where the first panel edge 101 and the second panel edge 102 are located, part of the circuit units 104 are arranged in a straight line along the first panel edge 101 on one side of the first panel edge 101, and part of the circuit units 104 are arranged in a straight line along the second panel edge 102 on one side of the second panel edge 102.

[0041] However, since there is a certain angle bend between the first panel edge 101 and the second panel edge 102, when the circuit unit 104 adopts the above-mentioned arrangement, the circuit unit 104 on the side of the first panel edge 101 and the circuit unit 104 on the side of the second panel edge 102 will have a sudden change in setting direction at the intersection of the two panel edges.

[0042] In the process of display panel manufacturing, when there is a big difference in the setting direction of the circuit unit 104, there may be a difference in the layout design of the two parts of the circuit unit 104, which will cause the width-to-length ratio of the transistors playing the same role in the two parts of the circuit unit 104 to be different, and thus cause differences in device performance. Moreover, such a setting will also cause a large gap between the two adjacent circuit units 104 at the intersection of the first panel edge 101 and the second panel edge 102, and the larger the gap between the two circuit units 104, the greater the risk of differences in device performance in the two circuit units 104. The above reasons will all lead to differences in the drive signals output by different circuit units 104, which will have an adverse effect on the display performance, for example, causing the display panel to have a split screen phenomenon.

[0043] To this end, an embodiment of the present invention provides a display panel, such as Figure 2 As shown, Figure 2 A schematic diagram of a structure of a display panel provided for the implementation of the present invention, the display panel comprises a first panel edge 1 and a second panel edge 2 which are adjacently connected, and the first panel edge 1 and the second panel edge 2 extend straightly in different directions, respectively. That is, there is a bend at a certain angle between the first panel edge 1 and the second panel edge 2. In the embodiment of the present invention, the angle between the first panel edge 1 and the second panel edge 2 can be an acute angle, a right angle or an obtuse angle.

[0044] The display panel further includes a display area 3 and a frame area 4 surrounding the display area 3 .

[0045] The display panel further includes a first functional circuit 5 located in the border area 4 . The first functional circuit 5 includes a plurality of first functional circuit units 6 . The plurality of first functional circuit units 6 include a plurality of first circuit units 61 , a plurality of second circuit units 62 and at least one third circuit unit 63 .

[0046] Among them, a plurality of first circuit units 61 are located on one side of the first panel edge 1 and are arranged in a straight line along the first panel edge 1, a plurality of second circuit units 62 are located on one side of the second panel edge 2 and are arranged in a straight line along the second panel edge 2, and at least one third circuit unit 63 is located between the first circuit unit 61 and the second circuit unit 62 and close to the junction of the first panel edge 1 and the second panel edge 2. Moreover, the setting direction of the third circuit unit 63 is inclined relative to the setting direction of the first circuit unit 61 and the setting direction of the second circuit unit 62.

[0047] In another expression of defining “the third circuit unit 63 is tilted”, as Figure 3 As shown, Figure 3 A schematic diagram of a partial structure of a display panel provided in an embodiment of the present invention, wherein the first functional circuit unit 6 includes a first edge 7 close to a side of the display area 3 and a second edge 8 intersecting with the first edge 7. A first angle A exists between the extension direction of the second edge 8 in the third circuit unit 63 and the extension direction of the second edge 8 in the first circuit unit 61, a second angle B exists between the extension direction of the second edge 8 in the third circuit unit 63 and the extension direction of the second edge 8 in the second circuit unit 62, and both the first angle A and the second angle B are smaller than a third angle C between the extension direction of the second edge 8 in the first circuit unit 61 and the extension direction of the second edge 8 in the second circuit unit 62.

[0048] In the embodiment of the present invention, by setting the third circuit unit 63 at the junction of the first panel edge 1 and the second panel edge 2, and making the setting direction of the third circuit unit 63 relatively inclined with the setting direction of the first circuit unit 61 and the second circuit unit 62, the setting direction of the entire first functional circuit unit 6 can be uniformly transitioned from an angle perpendicular to the first panel edge 1 to an angle perpendicular to the second panel edge 2, avoiding the rotation mutation of the setting direction of the circuit unit on one side of the two panel edges, thereby avoiding the layout difference caused by the sudden change of the setting direction, and weakening the device performance difference of the transistors in different first functional circuit units 6. Moreover, such a setting can also reduce the spacing between the first functional circuit units 6 near the junction of the two panel edges, thereby effectively weakening the performance difference of the transistors in different first functional circuit units 6.

[0049] In summary, the technical solution provided by the embodiment of the present invention can optimize the arrangement of the first functional circuit unit 6, thereby weakening the difference in the output signals of different first functional circuit units 6, and improving the display performance of the display panel, such as improving the split screen phenomenon of the display panel. The technical solution is particularly suitable for display panels with irregular shapes, such as more suitable for vehicle-mounted display screens with more diverse appearance designs.

[0050] In a possible implementation, Figure 4 As shown, Figure 4 Another partial structural diagram of a display panel provided by an embodiment of the present invention, the first functional circuit unit 6 includes a plurality of third circuit units 63, and the plurality of third circuit units 63 are arranged in the virtual ring 9 along the edge of the virtual ring 9. The center O of the virtual ring 9 is located in the display area 3, and the outer edge of the virtual ring 9 is tangent to the first panel edge 1 and the second panel edge 2, respectively.

[0051] In the above arrangement, at the junction of the first panel edge 1 and the second panel edge 2, a plurality of third circuit units 63 are arranged in rotation along the virtual ring 9. The differences in arrangement directions between two adjacent first circuit units 61 and third circuit units 63 and between two adjacent third circuit units 63 and second circuit units 62 are small, so that the arrangement directions of the first circuit unit 61, the third circuit unit 63 and the second circuit unit 62 can achieve a more uniform transition without a sudden change in arrangement direction.

[0052] Moreover, when the center of the virtual ring 9 is located in the display area 3, the outer edge of the virtual ring 9 and the vertex where the first panel edge 1 and the second panel edge 2 intersect will be spaced a certain distance apart, so that the space between the outer edge of the virtual ring 9 and the corner of the display area 3 is reduced. In this regard, the embodiment of the present invention can make the outer frame of the virtual ring 9 closer to the panel edge to a greater extent by making the outer edge of the virtual ring 9 tangent to the first panel edge 1 and the second panel edge 2 respectively, reducing the distance between the outer edge of the virtual ring 9 and the vertex where the two panel edges intersect, thereby leaving enough space between the outer edge of the virtual ring 9 and the corner of the display area 3 to accommodate the third circuit unit 63, thereby optimizing the arrangement of the third circuit unit 63.

[0053] When a plurality of third circuit units 63 are arranged along the edge of the virtual ring 9 in the virtual ring 9, in a feasible arrangement, refer again to Figure 4 At least one first circuit unit 61 close to the third circuit unit 63 is located in the virtual ring 9 , and at least one second circuit unit 62 close to the third circuit unit 63 is located in the virtual ring 9 .

[0054] In this way, the distance between the first circuit unit 61 and the first panel edge 1 and the distance between the third circuit unit 63 and the outer edge of the virtual ring 9 will not differ too much, and the first circuit unit 61 and the third circuit unit 63 will not have a sudden change in the setting position in the direction of the frame width where the first panel edge 1 is located. At the same time, the distance between the second circuit unit 62 and the second panel edge 2 and the distance between the third circuit unit 63 and the outer edge of the virtual ring 9 will not differ too much, and the third circuit unit 63 and the second circuit unit 62 will not have a sudden change in the setting position in the direction of the frame width where the second panel edge 2 is located.

[0055] This setting can avoid problems such as Figure 5 and Figure 6 The situation shown, where Figure 5 A schematic diagram of another partial structure of a display panel provided in an embodiment of the present invention is shown. Figure 6This is another partial structural diagram of a display panel provided by an embodiment of the present invention, which enables a smoother transition between the first circuit unit 61 and the third circuit unit 63 and between the arrangement positions of the third circuit unit 63 and the second circuit unit 62 .

[0056] When a plurality of third circuit units 63 are arranged along the edge of the virtual ring 9 in the virtual ring 9, in a feasible arrangement, refer again to Figure 4 There is a gap between the first circuit unit 61 and the first panel edge 1, there is a gap between the second circuit unit 62 and the second panel edge 2, and there is a gap between the third circuit unit 63 and the outer edge of the virtual ring 9, thereby preventing the first circuit unit 61 and the second circuit unit 62 from being flush with the panel edge of the display panel, and preventing the third circuit unit 63 from being too close to the panel edge of the display panel, thereby preventing water and oxygen from corroding the first functional circuit unit 6 and reducing the risk of device performance failure in the first functional circuit unit 6.

[0057] Further, in order to achieve a smoother transition between the first circuit unit 61, the second circuit unit 62 and the third circuit unit 63, refer again to Figure 4 , a distance d1 between the first circuit unit 61 and the first panel edge 1 , a distance d2 between the second circuit unit 62 and the second panel edge 2 , and a distance d3 between the third circuit unit 63 and the outer edge of the virtual ring 9 are equal.

[0058] In one possible implementation, see again Figure 4 , multiple third circuit units 63 are arranged at equal intervals. At this time, the angles between the setting directions of two adjacent third circuit units 63 tend to be equal. Multiple third circuit units 63 rotate evenly along the edge of the virtual ring 9 in the virtual ring 9, and the transition between the first circuit unit 61, the second circuit unit 62 and the third circuit unit 63 is softer.

[0059] In a possible implementation, Figure 7 As shown, Figure 7 This is another partial structural schematic diagram of a display panel provided in an embodiment of the present invention, wherein the border area 4 includes a first straight line border 10, a corner border 11, and a second straight line border 12 defined by a first panel edge 1 and a second panel edge 2, the first circuit unit 61 is located in the first straight line border 10, the second circuit unit 62 is located in the second straight line border 12, and the third circuit unit 63 is located in the corner border 11.

[0060] The frame width L1 of the first linear frame 10 is equal to the frame width L2 of the second linear frame 12 , and the distance d4 between the first circuit unit 61 and the display area 3 is equal to the distance d5 between the second circuit unit 62 and the display area 3 .

[0061] For a panel structure with two straight line frames of equal width, when the distance between the first circuit unit 61 and the display area 3 is equal to the distance between the second circuit unit 62 and the display area 3, the relative position relationship between the first circuit unit 61 and the panel edge of the display panel and the edge of the display area 3 in the first straight line frame 10 and the relative position relationship between the second circuit unit 62 and the panel edge of the display panel and the edge of the display area 3 in the second straight line frame 12 are the same, the first circuit unit 61 and the second circuit unit 62 can both be arranged sequentially along the third circuit unit 63 in the virtual ring 9, and the transition of the setting position of the first functional circuit unit 6 is softer.

[0062] Or, in another feasible implementation, as Figure 8 As shown, Figure 8 This is another partial structural schematic diagram of a display panel provided in an embodiment of the present invention, wherein the border area 4 includes a first straight line border 10, a corner border 11, and a second straight line border 12 defined by a first panel edge 1 and a second panel edge 2, the first circuit unit 61 is located in the first straight line border 10, the second circuit unit 62 is located in the second straight line border 12, and the third circuit unit 63 is located in the corner border 11.

[0063] The width L2 of the second linear frame 12 is greater than the width L1 of the first linear frame 10 , and the distance d5 between the second circuit unit 62 and the display area 3 is greater than the distance d4 between the first circuit unit 61 and the display area 3 .

[0064] For a panel structure with two straight line frames of unequal widths, when the width of the second straight line frame 12 is larger and the distance between the second circuit unit 62 and the display area 3 is larger, the first circuit unit 61 and the second circuit unit 62 are closer to the panel edge of the display panel, and the first circuit unit 61 and the second circuit unit 62 can both be arranged sequentially along the third circuit unit 63 in the virtual ring 9, and the transition of the setting position of the first functional circuit unit 6 is softer.

[0065] In a possible implementation, Fig. 9 As shown, Fig. 9 This is another partial structural schematic diagram of a display panel provided in an embodiment of the present invention, wherein the display panel also includes a second functional circuit 13 located in the border area 4, the second functional circuit 13 includes a plurality of second functional circuit units 14, at least some of the second functional circuit units 14 are located between the first functional circuit unit 6 on one side of the first sub-unit 15 and the display area 3, wherein the first sub-unit 15 is the third circuit unit 63 closest to the display area 3.

[0066] Since the first subunit 15 is the third circuit unit 63 closest to the display area 3, the distance between the first subunit 15 and the display area 3 is very small. When at least part of the second functional circuit unit 14 is arranged between the first functional circuit unit 6 next to the first subunit 15 and the display area 3, the second functional circuit unit 14 can be avoided from occupying the space between the first subunit 15 and the display area 3. Therefore, when designing the border width, there is no need to increase the border width in order to accommodate the second functional circuit unit 14 between the first subunit 15 and the display area 3, which helps to optimize the narrow border design.

[0067] Furthermore, if Fig.10 As shown, Fig.10 This is another partial structural diagram of a display panel provided in an embodiment of the present invention, wherein the first functional circuit unit 6 further includes a second subunit 16 and a plurality of third subunits 17, wherein the second subunit 16 is adjacent to the first subunit 15, and the third subunit 17 is located on the side of the second subunit 16 away from the first subunit 15. The spacing between the first subunit 15 and the second subunit 16 is greater than the distance between the remaining adjacent third circuit units 63. It should be noted that, depending on the position of the first subunit 15, the second subunit 16 may be the third circuit unit 63, or the first circuit unit 61 or the second circuit unit 62.

[0068] The plurality of second functional circuit units 14 include a fourth circuit unit 141 and a fifth circuit unit 142 , wherein at least a portion of the fourth circuit unit 141 is located between the first subunit 15 and the second subunit 16 , and the fifth circuit unit 142 is located on a side of the second subunit 16 and at least a portion of the third subunit 17 close to the display area 3 .

[0069] When the first subunit 15 is the third circuit unit 63 closest to the display area 3, the distance between the second subunit 16 adjacent to the first subunit 15 and the display area 3 may also be relatively small. In the above-mentioned arrangement, by increasing the distance between the first subunit 15 and the second subunit 16, a portion of accommodating space can be provided between the two for the fourth circuit unit 141, so that at least a portion of the fourth circuit unit 141 is inserted into the space between the first subunit 15 and the second subunit 16. In this way, when designing the frame width, there is no need to increase the distance between the second subunit 16 and the display area 3 for the fourth circuit unit 141, thereby optimizing the narrow frame design.

[0070] Further, see again Fig.10The display panel further includes a driving signal line 18 connected to the first functional circuit unit 6, and the driving signal line 18 may specifically include a frame start signal line, a clock signal line, etc. The driving signal line 18 includes at least one first signal line 19, and the first signal line 19 is located on a side of the second functional circuit 13 away from the display area 3 and extends close to the second functional circuit 13. The first signal line 19 includes a bending portion 20 located between the first subunit 15 and the second subunit 16, and the bending portion 20 is bent in a direction away from the display area 3, and at least part of the fourth circuit unit 141 is located on a side of the bending portion 20 close to the display area 3.

[0071] By bending the portion of the first signal line 19 between the first sub-unit 15 and the second sub-unit 16 , this portion of the line can avoid the fourth circuit unit 141 , thereby freeing up more space for the fourth circuit unit 141 .

[0072] In a possible implementation, Fig.11 and 12 As shown, Fig.11 A schematic diagram of another partial structure of a display panel provided in an embodiment of the present invention is shown. Fig.12 This is another partial structural diagram of a display panel provided by an embodiment of the present invention. The display panel further includes virtual sub-pixels 21 , and at least part of the virtual sub-pixels 21 are located between the fourth circuit unit 141 and the display area 3 .

[0073] Generally, the third circuit unit 63 (first subunit 15) closest to the display area 3 is located near the corner of the display area 3. The number of display subpixels 22 connected to the data line Data near the corner of the display area 3 is usually small, resulting in a small load. When at least part of the fourth circuit unit 141 is accommodated between the first subunit 15 and the second subunit 16, the space released by the fourth circuit unit 141 can be used to set the virtual subpixel 21, so that this part of the virtual subpixel 21 is connected to the data line Data at the corner of the display area 3, thereby effectively improving the load uniformity of the data line Data at different positions.

[0074] In a possible implementation, Fig.13 As shown, Fig.13 This is another partial structural schematic diagram of the display panel provided in an embodiment of the present invention, wherein the second functional circuit 13 includes a first-type second functional circuit 13_1, the second subunit 16 includes a first-type second subunit 16_1, and the third subunit 17 includes a first-type third subunit 17_1, wherein the first-type second subunit 16_1 and the first-type third subunit 17_1 are located on one side of the first subunit 15, and the first-type third subunit 17_1 includes a first circuit unit 61.

[0075] In the first type second functional circuit 13_1 , at least part of the fourth circuit unit 141 is located between the first subunit 15 and the first type second subunit 16_1 , and the fifth circuit unit 142 is located on a side of the first type second subunit 16_1 and at least part of the first type third subunit 17_1 close to the display area 3 .

[0076] It should be noted that when the first type third subunit 17_1 includes the first circuit unit 61, it means that the first type second functional circuit 13_1 is located in the frame on one side of the first panel edge 1. In addition, according to the different positions of the first subunit 15, the first type third subunit 17_1 may also include a third circuit unit 63.

[0077] And / or, the second functional circuit 13 includes a second type second functional circuit 13_2, the second subunit 16 includes a second type second subunit 16_2, and the third subunit 17 includes a second type third subunit 17_2. The second type second subunit 16_2 and the second type third subunit 17_2 are located on the other side of the first subunit 15, and the second type third subunit 17_2 includes a second circuit unit 62.

[0078] In the second type second functional circuit 13_2 , at least part of the fourth circuit unit 141 is located between the first subunit 15 and the second type second subunit 16_2 , and the fifth circuit unit 142 is located on a side of the second type second subunit 16_2 and at least part of the second type third subunit 17_2 close to the display area 3 .

[0079] It should be noted that when the second type third subunit 17_2 includes the second circuit unit 62, it means that the second type second functional circuit 13_2 is located in the frame on one side of the second panel edge 2. In addition, according to the different positions of the first subunit 15, the second type third subunit 17_2 may also include a third circuit unit 63.

[0080] In the above arrangement, the second functional circuits 13 can be respectively arranged on one side of the first panel edge 1 and the second panel edge 2. This arrangement is suitable for a panel structure with a large number of second functional circuits 13.

[0081] Further, see Fig.14 and Fig.15 The display panel further includes a data line Data located in the display area 3. The frame area 4 further includes a binding area 23, which can be used to bind structures such as a driver chip and a printed circuit board. The distance between the first circuit unit 61 and the binding area 23 is greater than the distance between the second circuit unit 62 and the binding area 23.

[0082] Based on this, the first type second functional circuit 13_1 may include a protection circuit 24 connected to the data line Data (not shown in the figure), and the protection circuit 24 is used to protect the data line Data to prevent the data line Data from being broken down by static electricity. The second type second functional circuit 13_2 includes a gating circuit 25 connected to the data line Data (not shown in the figure), and the gating circuit 25 is used to transmit the data voltage to the data line Data in a time-sharing manner, thereby reducing the number of pins in the binding area 23.

[0083] Since the selection circuit 25 needs to receive the data voltage provided by the driving chip or printed circuit board, the second type second functional circuit 13_2 closer to the binding area 23 is set as the selection circuit 25, which can reduce the connection distance between the selection circuit 25 and the binding area 23, facilitate wiring and reduce voltage drop.

[0084] Furthermore, if Fig.14 As shown, Fig.14 This is another partial structural diagram of a display panel provided by an embodiment of the present invention, wherein the display panel further comprises a third panel edge 26, and the extension direction of the third panel edge 26 is perpendicular to the extension direction of the data line Data. The binding area 23 is located on one side of the third panel edge 26, and the second type second functional circuit 13_2 is connected to the pin in the binding area 23 via a connecting lead 29.

[0085] Since the selection circuit 25 needs to receive the data voltage provided by the driving chip or the printed circuit board, when the binding area 23 and the second-type second-function circuit 13_2 (selection circuit 25) are located on different sides of the frame, the second-type second-function circuit 13_2 (selection circuit 25) can be connected to the pins in the binding area 23 through the connecting lead 29, thereby achieving connection with the driving chip or the printed circuit board.

[0086] Moreover, based on the above configuration, the second type second functional circuit 13_2 (selection circuit 25) is close to the binding area 23, so the extension length of the connecting lead 29 can be shortened, and the attenuation of the data voltage during the transmission process can be reduced.

[0087] Or, if Fig.15 As shown, Fig.15 This is another partial structural diagram of a display panel provided by an embodiment of the present invention. The binding area 23 is located between the second circuit unit 62 and the second panel edge 2 , and the second type second functional circuit 13_2 is connected to the pins in the binding area 23 through the connecting lead 29 .

[0088] Since the selection circuit 25 needs to receive the data voltage provided by the driving chip or the printed circuit board, when the binding area 23 and the second type second functional circuit 13_2 (selection circuit 25) are located on the same side of the frame, the second type second functional circuit 13_2 (selection circuit 25) can be connected to the pins in the binding area 23 through the connecting lead 29, thereby achieving connection with the driving chip or the printed circuit board.

[0089] Moreover, based on the above configuration, the second type second functional circuit 13_2 (selection circuit 25) is close to the binding area 23, so the extension length of the connecting lead 29 can be shortened, and the attenuation of the data voltage during the transmission process can be reduced.

[0090] It should be noted that when the binding area 23 and the second type of second functional circuit 13_2 (selection circuit 25) are located on the same side of the frame, the display panel may not have a lower frame, and the display panel may be in a rhombus or other shape. Alternatively, the display panel may also have a lower frame, for example, the extension direction of the second panel edge 2 is perpendicular to the extension direction of the data line Data, and the side where the second circuit unit 62 is located is the lower frame, and the display panel may be in a parallelogram or other shape.

[0091] In a possible implementation, Fig.16 and Fig.17 As shown, Fig.16 A schematic diagram of another partial structure of a display panel provided in an embodiment of the present invention is shown. Fig.17 A schematic diagram of a panel edge, a data line Data, and a pixel row 28 provided in an embodiment of the present invention, wherein the first functional circuit 5 includes a shift register circuit 27. The display area 3 includes the data line Data, an angle θ1 between an extension direction of the first panel edge 1 and an extension direction of the data line Data is greater than an angle θ2 between an extension direction of the second panel edge 2 and an extension direction of the data line Data, and a spacing h1 between adjacent first circuit units 61 is greater than a spacing h2 between adjacent second circuit units 62.

[0092] It should be noted that Fig.17 The reference numeral 1_1 in the figure represents a straight line parallel to the edge 1 of the first panel, and the angle between the straight line and the data line Data is the angle θ1 between the extension direction of the first panel edge 1 and the extension direction of the data line Data. The reference numeral 2_1 represents a straight line parallel to the edge 2 of the second panel, and the angle between the straight line and the data line Data is the angle θ2 between the extension direction of the second panel edge 2 and the extension direction of the data line Data.

[0093] The shift register circuit 27 is usually electrically connected to the pixel row 28 through a scanning signal line, a light emitting control signal line, etc. Fig.17, when the angle between the panel edge and the extension direction of the data line Data is larger, the angle between the panel edge and the extension direction of the pixel row 28 is smaller, then at the same length, the number of first functional circuit units 6 corresponding to one side of the panel edge is less, so the arrangement of the first functional circuit units 6 on the side of the panel edge can be made sparser. Under this setting mode, there is a correlation between the arrangement density of the first functional circuit units 6 on one side of the panel edge and the angle between the extension direction of the first panel edge 1 and the extension direction of the data line Data, and the arrangement mode of the first functional circuit units 6 on different sides of the panel edge can be optimized.

[0094] In a possible implementation, Fig.18 As shown, Fig.18 This is another partial structural schematic diagram of a display panel provided in an embodiment of the present invention, in which the spacing between adjacent third circuit units 63 is smaller than the spacing between adjacent first circuit units 61 and larger than the spacing between adjacent second circuit units 62, so that the arrangement density of the third circuit units 63 is between the arrangement density of the first circuit units 61 and the arrangement density of the second circuit units 62, thereby achieving a uniform transition.

[0095] Further, see again Fig.18 , along the direction pointing to the third circuit unit 63, the spacing between adjacent first circuit units 61 decreases, and / or, along the direction pointing to the second sub-circuit, the spacing between adjacent third circuit units 63 decreases, and / or, along the direction away from the third circuit unit 63, the spacing between adjacent second circuit units 62 decreases. At this time, from the first circuit unit 61 to the third circuit unit 63 and then to the second circuit unit 62, the arrangement density between the multiple circuit units decreases, and the arrangement density changes gradually, which can better achieve a uniform transition.

[0096] In a possible implementation, Fig.19 As shown, Fig.19 This is another partial structural diagram of a display panel provided by an embodiment of the present invention, wherein the first functional circuit 5 includes a shift register circuit 27. The display area 3 includes a data line Data, an angle θ1 between an extension direction of the first panel edge 1 and an extension direction of the data line Data is equal to an angle θ2 between an extension direction of the second panel edge 2 and an extension direction of the data line Data, and a spacing h1 between adjacent first circuit units 61 is equal to a spacing h2 between adjacent second circuit units 62.

[0097] Combined with the above analysis, when the angles between the extension directions of the first panel edge 1 and the second panel edge 2 and the first direction are equal, the angles between the panel edge and the extension directions of the pixel row 28 are equal, and at the same length, the number of first functional circuit units 6 corresponding to one side of the panel edge is equal, so the circuit units on one side of the two panel edges can be arranged with equal density.

[0098] In a feasible implementation, the display area 3 includes a scan signal line, the first functional circuit 5 includes a first shift register circuit, the first circuit functional unit 6 in the first shift register circuit is electrically connected to the scan signal line, and the first circuit functional unit 6 is used to sequentially output the scan signal to the scan signal line. And / or, the display area 3 includes a light-emitting control signal line, the first functional circuit 5 includes a second shift register circuit, the first circuit functional unit 6 in the second shift register circuit is electrically connected to the light-emitting control signal line, and the first circuit functional unit 6 is used to sequentially output the light-emitting control signal to the light-emitting control signal line. And / or, the display area 3 includes a data line Data, the first functional circuit 5 includes a gating circuit, the first circuit functional unit 6 in the gating circuit is electrically connected to the data line Data, and the first circuit functional unit 6 is used to transmit the data voltage to different data lines Data in time-sharing.

[0099] Exemplarily, in one configuration, when the display panel is a liquid crystal display panel, the first functional circuit 5 may include at least one of a first shift register circuit and a gating circuit. When the display panel is an organic light emitting diode display panel, the first functional circuit 5 may include at least one of a first shift register circuit, a second shift register circuit, and a gating circuit.

[0100] It should be noted that the structures and functions of the first shift register circuit, the second shift register circuit and the gating circuit are the same as those in the prior art and will not be described in detail here.

[0101] In addition, it should be noted that the extension direction of the first panel edge 1 and the second panel edge 2 in the drawings provided in the embodiments of the present invention are only for schematic illustration.
