[0036] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without any creative work fall within the scope of protection of the present application.

[0037] Please refer to Figure 1 , Figure 1 A structural schematic view of one embodiment of the display panel in the present application, which can be an OLED display panel, an LED display panel, a liquid crystal display panel, etc. The display panel includes a display area 10 and a non-display area 12; the non-display area 12 includes a first fan-out area 14 and a second fan-out area 16 arranged along a first direction X; the first fan-out area 14 is located between the display area 10 and the second fan-out area 16.

[0038] Optionally, as shown in Figure 2 , Figure 2 For Figure 1 A partial enlarged schematic view of one embodiment in the middle; Figure 3 For Figure 1This is a partially enlarged schematic diagram of another embodiment. The first fan-out area 14 includes a plurality of first sub-areas 140 arranged along the second direction Y. Each first sub-area 140 includes a plurality of first conductor segments 200 arranged along the second direction Y. In any first sub-area 140, the density of the arrangement of the first conductor segments 200 near the first end 2000 of the display area 10 is less than the density of the arrangement of the first conductor segments 200 away from the second end 2002 of the display area 10. This is equivalent to the length occupied by the first ends 2000 of the plurality of first conductor segments 200 in the second direction Y being greater than the length occupied by the second ends 2002 of the plurality of first conductor segments 200 in the second direction Y in any first sub-area 140. In any first sub-area 140, the two first conductor segments 200 furthest apart (i.e., Figure 3 In the first sub-region 140, the distance 2000 of the first ends 2000 of the leftmost and rightmost first conductor segments 200 in the second direction Y is greater than the distance 2002 of their second ends 200 in the second direction Y. In the first fan-out region 14, the length d3 occupied by the first ends 2000 of all the first conductor segments 200 in the second direction Y is greater than the length d4 occupied by the second ends 2002 of all the first conductor segments 200 in the second direction Y. In the first fan-out region 14, the distance d3 of the first ends 2000 of the two farthest first conductor segments 200 (i.e., the leftmost and rightmost first conductor segments 200 in the first fan-out region 14) in the second direction Y is greater than the distance d4 of their second ends 2002 in the second direction Y. In any first sub-region 140, the first ends 2000 of multiple first conductor segments 200 can be arranged at equal intervals in the second direction Y and are parallel to each other. In any first sub-region 140, the second ends 2002 of a plurality of first conductor segments 200 can be arranged at equal intervals in the second direction Y and are parallel to each other. In any first sub-region 140, the distance between the first ends 2000 of two adjacent first conductor segments 200 in the second direction Y can be greater than the distance between their second ends 2002 in the second direction Y. In any first sub-region 140, the distance between the first ends 2000 of two adjacent first conductor segments 200 perpendicular to their extension direction (i.e., the minimum distance) is equal to the distance between their second ends 2002 in the second direction Y.

[0039] The second fan-out area 16 includes a plurality of second sub-areas 160 arranged along the second direction Y. Each second sub-area 160 includes a plurality of second conductor segments 202 arranged along the second direction Y. In any second sub-area 160, the density of the arrangement of the second conductor segments 202 near the first end 2020 of the display area 10 is greater than the density of the arrangement of the second conductor segments 202 away from the display area 10. In any second sub-area 160, the length occupied by the first end 2020 of the plurality of second conductor segments 202 in the second direction Y is less than the length occupied by the second end 2022 of the plurality of second conductor segments 202 in the second direction Y. In any second sub-area 160, the two second conductor segments 202 that are furthest apart (i.e., Figure 2 In the second sub-region 160, the distance between the first ends 2020 of the leftmost and rightmost second conductor segments 202 in the second direction Y is less than the distance between their second ends 2022 in the second direction Y. In the second fan-out region 16, the length occupied by the first ends 2020 of all second conductor segments 202 in the second direction Y is greater than the length occupied by the second ends 2022 of all second conductor segments 202 in the second direction Y. In the second fan-out region 16, the distance between the first ends 2020 of the two farthest second conductor segments 202 (i.e., the leftmost and rightmost second conductor segments 202 in the second fan-out region 16) in the second direction Y is greater than the distance between their second ends 2022 in the second direction Y. In any second sub-region 160, the first ends 2020 of multiple second conductor segments 202 can be arranged at equal intervals in the second direction Y and are parallel to each other. In any second sub-region 160, the second ends 2022 of multiple second conductor segments 202 can be arranged at equal intervals in the second direction Y and are parallel to each other. In any second sub-region 160, the spacing between the first ends 2020 of a plurality of second conductor segments 202 in the second direction Y is less than the spacing between the second ends 2022 in the second direction Y. In any second sub-region 160, the spacing between the first ends 2020 of two adjacent second conductor segments 202 in the second direction Y is equal to the spacing between their second ends 2022 in the direction perpendicular to their extension.

[0040] In the above design, in the direction away from the display area 10, the arrangement of the first conductor segments 200 in the multiple spaced first sub-areas 140 of the first fan-out area 14 is from sparse to dense, and the arrangement of the second conductor segments 202 in the multiple spaced second sub-areas 160 of the second fan-out area 16 is from dense to sparse. This ensures that, at least in the same first sub-area 140 located on the outer side of the first fan-out area 14 along the second direction Y, the length of the first conductor segments 202 gradually increases or decreases sequentially when viewed along the second direction Y. For example, the length of the first conductor segments 202 in the leftmost first sub-area 140 of the first fan-out area 14 decreases sequentially from left to right; the length of the first conductor segments 202 in the rightmost first sub-area 140 of the first fan-out area 14 decreases sequentially from right to left; at least in the second fan-out area 16 along the second direction Y, the length of the first conductor segments 202 gradually decreases. In the same second sub-region 160 on the outer side, the length of the second conductor segment 202 is gradually increasing or decreasing along the second direction Y. For example, the length of the second conductor segment 202 in the leftmost second sub-region 160 of the second fan-out region 16 increases from left to right; the length of the second conductor segment 202 in the rightmost second sub-region 160 of the second fan-out region 16 increases from right to left. In the corresponding connected first sub-regions 140 and second sub-regions 160 on the outer side, the direction in which the longest first conductor segment 200 points to the shortest first conductor segment 200 is opposite to the direction in which the longest second conductor segment 200 points to the shortest second conductor segment 200, so that the longer first conductor segment 200 is electrically connected to the shorter second conductor segment 200, and the shorter first conductor segment 200 is electrically connected to the longer second conductor segment 200. Compared to... Figure 4 As shown, by setting the conductor segments of multiple second sub-regions in the second fan-out region 16' as straight lines extending along the first direction, and by making the conductor segments of the second sub-regions have the same tightness at both ends (which cannot compensate for the impedance difference of the first fan-out region 14'), this embodiment can reduce the impedance difference.

[0041] The length of the first conductor segment 200 in the first sub-region 140 of the middle region of the first fan-out area 14 can be set from left to right by first decreasing and then increasing, or decreasing or increasing sequentially, or increasing first and then decreasing, as needed. The length of the second conductor segment 202 in the second sub-region 160 of the middle region of the second fan-out area 16 can be set from left to right by first increasing and then decreasing, or decreasing or increasing sequentially, or decreasing first and then increasing, as needed.

[0042] Optionally, such as Figure 1As shown, the first fan-out area 14 is an axisymmetric shape. Optionally, the second fan-out area 16 is also an axisymmetric shape. Optionally, the axis of symmetry of the first fan-out area 14 is parallel to the first direction X. Optionally, the axis of symmetry of the second fan-out area 16 is parallel to the first direction X. Optionally, the axes of symmetry of the first fan-out area 14 and the second fan-out area 16 are parallel to the first direction X and collinear; this design can reduce wiring difficulty and manufacturing complexity.

[0043] Optionally, the first direction X and the second direction Y mentioned above can be different, for example, they can be perpendicular. This design allows for neater wiring in the first fan-out area 14 and the second fan-out area 16, and the manufacturing process is easier.

[0044] In one implementation, please refer to [link / reference needed]. Figure 3 Optionally, in two adjacent first sub-regions 140, the distance d1 along the second direction Y between the first ends 2000 of the two closest first conductor segments 2000 located in different first sub-regions 140 is less than the distance d2 along the second direction Y between their second ends 2002. Optionally, in two adjacent second sub-regions 160, the distance d5 along the second direction Y between the first ends 2020 of the two closest second conductor segments 202 located in different second sub-regions 160 is greater than the distance d6 along the second direction Y between their second ends 2022. That is, in the second direction Y, in the two closest first conductor segments 200 of two adjacent first sub-regions 140, one is shorter and the other is longer; in the two closest second conductor segments 202 of two adjacent second sub-regions 160, one is longer and the other is shorter; and during electrical connection, the shorter first conductor segment 200 is connected to the longer second conductor segment 202, and the longer first conductor segment 200 is connected to the shorter second conductor segment 202, in order to reduce impedance difference.

[0045] Please continue to combine Figure 1 to Figure 3 As shown, in the first fan-out region 14, the two first conductor segments 200 (farthest apart) Figure 1 The first end 2000 (not marked in the text) Figure 1 (Not marked in the text) The distance d3 along the second direction Y is greater than the distance d4 along the second direction Y of its second end 2002. In the second fan-out region 16, the two second conductor segments 202 that are furthest apart ( Figure 1 The first end of 2020 (not marked in the text) Figure 1 (Not shown) The distance d7 along the second direction Y is greater than the distance d8 along the second direction Y of its second end 2022. That is, from the overall perspective, the width of the first fan-out area 14 and the second fan-out area 16 is reduced in the first direction X. This design can reduce the size occupied by the first fan-out area 14 and the second fan-out area 16 in the second direction Y, so as to reserve space for other components or wiring.

[0046] Please continue to refer to Figure 1 to Figure 3 , the first sub-area 140 and the second sub-area 160 are arranged one by one in correspondence; the first conductive segment 200 and the second conductive segment 202 in the corresponding first sub-area 140 and the second sub-area 160 are electrically connected one by one.

[0047] Optionally, in the same first sub-area 140 located at the outermost side of the first fan-out area 14 along the second direction Y, the longer the first conductive segment 200, the shorter the second conductive segment 202 electrically connected thereto. For example, in the first sub-area 140 located at the leftmost side of the first fan-out area 14, the longer the first conductive segment 200, the shorter the second conductive segment 202 electrically connected thereto. For example, in the first sub-area 140 located at the rightmost side of the first fan-out area 14, the longer the first conductive segment 200, the shorter the second conductive segment 202 electrically connected thereto. Preferably, for any first sub-area 140, the longer the first conductive segment 200, the shorter the second conductive segment 202 electrically connected thereto. At this time, the second fan-out area 16 is equivalent to an area for resistance compensation of the conductive segments in the first fan-out area 14, so as to reduce the impedance difference between the fan-out lines formed by the electrically connected first conductive segment 200 and the second conductive segment 202, and improve the display effect.

[0048] Optionally, in the corresponding first sub-area 140 and the second sub-area 160, the arrangement density of the second end 2002 of the first conductive segment 200 away from the display area 10 is equal to the arrangement density of the first end 2020 of the second conductive segment 202 close to the display area 10. Generally, the bending area 11 is arranged between the first fan-out area 14 and the second fan-out area 16, and this design can reduce the wiring difficulty of the bending area 11, for example, the trace in the bending area 11 can be a straight line.

[0049] Optionally, in the same first sub-area 140 located at the outermost side of the first fan-out area 14 along the second direction Y, the first conductive segment 200 and the corresponding second conductive segment 202 have the same resistance value in series. For example, in the first sub-area 140 located at the leftmost side of the first fan-out area 14, the first conductive segment 200 and the corresponding second conductive segment 202 have the same resistance value in series. For example, in the first sub-area 140 located at the rightmost side of the first fan-out area 14, the first conductive segment 200 and the corresponding second conductive segment 202 have the same resistance value in series. Preferably, all the first conductive segments 200 and the corresponding second conductive segments 202 in the first fan-out area 14 have the same resistance value in series. This design can make the overall resistance of the fan-out line formed by any electrically connected first conductive segment 200 and the second conductive segment 202 the same, so as to reduce the impedance difference between the adjacent two fan-out lines, and further improve the display effect of the display panel and reduce the probability of generating vertical vertical stripe display defects.

[0050] Optionally, in the same first sub-area 140 located at the two opposite sides of the first fan-out area 14 along the second direction Y, the line width of the first conductive line segment 200 is equal to that of the corresponding second conductive line segment 202. For example, in the first sub-area 140 located at the leftmost side of the first fan-out area 14, the line width of the first conductive line segment 200 is equal to that of the corresponding second conductive line segment 202. For example, in the first sub-area 140 located at the rightmost side of the first fan-out area 14, the line width of the first conductive line segment 200 is equal to that of the corresponding second conductive line segment 202. Preferably, the line width of all the first conductive line segments 200 located in the first fan-out area 14 is equal to that of the corresponding second conductive line segment 202.

[0051] Optionally, in the corresponding first sub-area 140 and second sub-area 160, the line distance between two adjacent first conductive line segments 200 located in the first sub-area 140 is equal to that between two adjacent second conductive line segments 202 located in the second sub-area 160. The line distance, also known as the line spacing, is generally defined as the shortest distance between two non-intersecting straight lines, which is the distance of the common perpendicular segment between the two straight lines. For example, as shown in FIG. 1, the line distance between two adjacent first conductive line segments 200 is equal to that between two adjacent second conductive line segments 202. Figure 3 Optionally, the first conductive line segment 200 and the second conductive line segment 202 are both broken lines, each of which includes a portion at an acute angle with the second direction Y and a portion perpendicular to the second direction Y. The first conductive line segment 200 and the second conductive line segment 202 have a first line distance between the portions perpendicular to the second direction Y, a second line distance between the portions at an acute angle with the second direction Y, a third line distance between the portions perpendicular to the second direction Y of two adjacent second conductive line segments 202, and a fourth line distance between the portions at an acute angle with the second direction Y of two adjacent second conductive line segments 202. The first line distance, the second line distance, the third line distance, and the fourth line distance are all equal. Generally, the impedance is related to not only the resistance of the line itself but also the capacitive reactance between the lines, which is generally related to the line distance between the lines and the line width of the lines. The above design can make the capacitive reactance between the adjacent first conductive line segments 200 and the electrically connected second conductive line segments 202 have little difference, so as to further improve the display effect.

[0052] Optionally, in the corresponding first sub-area 140 and second sub-area 160, the distance between the second ends 2002 of two adjacent first conductive line segments 200 away from the display area 10 along the second direction Y is equal to the distance between the first ends 2020 of two adjacent second conductive line segments 202 close to the display area 10 along the second direction Y.

[0053] Please continue to refer to Figure 3The absolute value of the difference between the size of the first fan-out area 14 along the first direction X and the size of the second fan-out area 16 along the first direction X is greater than or equal to 0 and less than or equal to 500 microns, for example, the absolute value of the difference is 100 microns, 200 microns, 300 microns, etc. This design can make it easier for the above design to make the series resistance of the first wire segment 200 and the corresponding second wire segment 202 the same.

[0054] Please continue to refer to Figure 3 Optionally, at least part of the first wire segment 200 is a broken line shape, for example, it can be two segments of broken line shape with an obtuse angle. Optionally, at least part of the second wire segment 202 is a broken line shape, for example, it can be two segments of broken line shape with an obtuse angle. This design can reduce the difficulty of the preparation process of the first wire segment 200 and the second wire segment 202. Optionally, the extension direction of the first wire segment 200 away from the second end 2002 of the display area 10 is parallel to the first direction Y. Optionally, the extension direction of the second wire segment 202 close to the first end 2000 of the display area 10 is parallel to the first direction Y. When the bending area 11 is arranged between the first fan-out area 14 and the second fan-out area 16, this design can reduce the difficulty of wiring the bending area 11. Of course, in other embodiments, the first wire segment 200 and the second wire segment 202 can also have other shapes, for example, arc shape, etc., which are not limited in the present application.

[0055] In one application scenario, in the same first sub-area 140 on the outermost side of the first fan-out area 14 along the second direction Y, for example, it can be the leftmost first sub-area 140 or the rightmost first sub-area 140, the first wire segment 200 in broken line shape close to the first end 2000 of the display area 10 is inclined in the same direction relative to the second end 2002 of the first wire segment 200. That is, for a plurality of first wire segments 200 in the same first sub-area 140 on the outermost side, the angle between the first end 2000 and the second end 2002 on the same first wire segment 200 is the same, for example, the first ends 2000 of the plurality of first wire segments 200 can be arranged parallel to each other, and the second ends 2002 of the plurality of first wire segments 200 can be arranged parallel to each other. This design can reduce the difficulty of wiring and process preparation, and can reduce the size of the end of the first fan-out area 14 in the direction away from the display area 10 in the second direction Y, to reduce the size occupied by the first fan-out area 14.

[0056] Optionally, in the outermost different first sub-regions 140 located at opposite sides of the first fan-out region 14 along the second direction Y, the first conductive line segments 200 in the shape of a broken line are inclined towards different directions relative to the second end 2002 of the first conductive line segment 200 close to the first end 2000 of the display region 10. For example, in the leftmost first sub-region 140, the first conductive line segment 200 in the shape of a broken line is inclined towards the left relative to the second end 2002 of the first conductive line segment 200 close to the first end 2000 of the display region 10. For example, in the rightmost first sub-region 140, the first conductive line segment 200 in the shape of a broken line is inclined towards the right relative to the second end 2002 of the first conductive line segment 200 close to the first end 2000 of the display region 10. That is, the first conductive line segments 200 in the two outermost first sub-regions 140 are inclined in different manners, for example, can be arranged in an axial symmetry. This design can reduce the size of the end of the first fan-out region 14 in the direction away from the display region 10 along the second direction Y, so as to reduce the size of the first fan-out region 14.

[0057] In addition, in the same first sub-region 140 located in the middle region of the first fan-out region 14, the first conductive line segments 200 in the shape of a broken line are inclined towards different directions relative to the second end 2002 of the first conductive line segment 200 close to the first end 2000 of the display region 10. That is, the first conductive line segments 200 in the first sub-region 140 located in the middle region can be inclined in different manners, so as to improve the flexibility of the wiring and facilitate reducing the size of the first fan-out region 14 along the second direction Y. Optionally, in the same first sub-region 140 located in the middle region of the first fan-out region 14, the leftmost first conductive line segment 200 in the shape of a broken line is inclined towards the left relative to the second end 2002 of the first conductive line segment 200 close to the first end 2000 of the display region 10; and the rightmost first conductive line segment 200 in the shape of a broken line is inclined towards the right relative to the second end 2002 of the first conductive line segment 200 close to the first end 2000 of the display region 10. Optionally, the first sub-region 140 located in the middle region of the first fan-out region 14 can be an axial symmetry pattern, and optionally, the symmetry axis is parallel to the first direction X.

[0058] Similarly, optionally, the second wire segments 202 in the same second sub-area 160 located at the outermost side of the second fan-out area 16 along the second direction Y, for example, the leftmost second sub-area 160 or the rightmost second sub-area 160, can be inclined away from the second end 2022 of the display area 10 relative to the first end 2020 of the second wire segment 202 in the same direction; that is, for the plurality of second wire segments 202 located in the same second sub-area 160 at the outermost side, the included angle between the first end 2020 and the second end 2022 of the same second wire segment 202 is the same, for example, the first ends 2020 of the plurality of second wire segments 202 can be arranged parallel to each other, and the second ends 2022 of the plurality of second wire segments 202 can be arranged parallel to each other. This design can reduce the difficulty of wiring and process preparation, and can reduce the size of the second end of the second fan-out area 16 in the second direction Y away from the display area 10, so as to reduce the size occupied by the second fan-out area 16.

[0059] Optionally, the second wire segments 202 in different second sub-areas 160 located at the outermost side of the second fan-out area 16 along the second direction Y are inclined away from the second end 2022 of the display area 10 relative to the first end 2020 of the second wire segment 202 in different directions. For example, in the leftmost second sub-area 160, the second wire segment 202 is inclined away from the second end 2022 of the display area 10 relative to the first end 2020 of the second wire segment 202 to the right. For example, in the rightmost second sub-area 160, the second wire segment 202 is inclined away from the second end 2022 of the display area 10 relative to the first end 2020 of the second wire segment 202 to the left. That is, the inclination of the second wire segment 202 in the two second sub-areas 160 at the outermost side is different. This design can reduce the size of the second end of the second fan-out area 16 in the second direction Y away from the display area 10, so as to reduce the size occupied by the second fan-out area 16.

[0060] Optionally, in the same second sub-area 160 in the middle region of the second fan-out area 16, the second wire segments 202 in the shape of a broken line are inclined in different directions away from the second end 2022 of the display area 10 relative to the first end 2020 of the second wire segment 202. That is, in the second sub-area 160 in the middle region, the different second wire segments 202 can be inclined in different ways to improve the flexibility of the wiring and facilitate reducing the size of the second fan-out area 16 in the second direction Y. For example, in the same second sub-area 160 in the middle region of the second fan-out area 16, the leftmost second wire segment 202 in the shape of a broken line is inclined to the left away from the second end 2022 of the display area 10 relative to the first end 2020 of the second wire segment 202; and the rightmost second wire segment 202 in the shape of a broken line is inclined to the right away from the second end 2022 of the display area 10 relative to the first end 2020 of the second wire segment 202. Optionally, the second sub-area 160 in the middle region of the second fan-out area 16 can be an axisymmetric pattern, and the axis of symmetry is parallel to the first direction X.

[0061] Optionally, in the corresponding first sub-area 140 and second sub-area 160 on opposite sides along the second direction Y, in the first wire segment 200 and the second wire segment 201 in the shape of a broken line and electrically connected, the first end 2000 of the first wire segment 200 and the second end 2022 of the second wire segment 202 extend in the second direction in opposite directions, and the first end 2000 of the first wire segment 200 and the second end 2022 of the second wire segment 202 extend in the first direction in opposite directions. For example, the first end 2000 of the first wire segment 200 extends away from the middle region of the first fan-out area 14, and the second end 2022 of the second wire segment 202 extends toward the middle region of the second fan-out area 16. For example, in the leftmost corresponding first sub-area 140 and second sub-area 160, in the first wire segment 200 and the second wire segment 202 in the shape of a broken line and electrically connected, the first end 2000 of the first wire segment 200 extends to the upper left, and the second end 2022 of the second wire segment 202 extends to the lower right. For example, in the rightmost corresponding first sub-area 140 and second sub-area 160, in the first wire segment 200 and the second wire segment 201 in the shape of a broken line and electrically connected, the first end 2000 of the first wire segment 200 extends to the upper right, and the second end 2022 of the second wire segment 202 extends to the lower left.

[0062] Please continue to refer to Figure 1 to Figure 3 Optionally, the non-display area 12 further comprises a bending area 11 between the first fan-out area 14 and the second fan-out area 16. After the bending area 11 is bent, the first fan-out area 14 and the second fan-out area 16 can be stacked and spaced apart.

[0063] Optionally, the bending region 11 comprises a plurality of third sub-regions 110 arranged along the second direction Y at intervals, any third sub-region 110 comprises a plurality of fourth conductor segments 206 arranged along the second direction Y. Optionally, the extending direction of the fourth conductor segment 206 is parallel to the first direction X. This design can reduce the difficulty of wiring of the bending region 11, and reduce the probability of fracture of the fourth conductor segment 206 in the bending region 11 when bending. Preferably, the resistance of all fourth conductor segments 206 in the bending region 11 is the same.

[0064] In adjacent two third sub-regions 110, the distance between the fourth conductor segments 206 located in different third sub-regions 110 and closest to each other in the second direction Y is greater than the distance between adjacent fourth conductor segments 206 located in the same third sub-region 110 in the second direction Y. Compared with equally distributing all fourth conductor segments 206 of the bending region 110, this design can make the distance between the fourth conductor segments 206 of different third sub-regions 110 larger, and reduce the probability of mutual short circuit between the fourth conductor segments 206 of adjacent third sub-regions 110 in the bending process.

[0065] Optionally, the first sub-region 140, the second sub-region 160 and the third sub-region 110 are arranged one by one; in the corresponding first sub-region 140, the second sub-region 160 and the third sub-region 110, the first conductor segment 200 is electrically connected with the corresponding second conductor segment 202 through the corresponding fourth conductor segment 206. This electrical connection is relatively simple, and the process is easy to implement.

[0066] Please continue to refer to Figure 1 to Figure 3 Optionally, the non-display region 12 further comprises a third fan-out region 18, the second fan-out region 16 is located between the first fan-out region 14 and the third fan-out region 18, and the third fan-out region 18 comprises a plurality of third conductor segments 204 arranged along the second direction Y. The arrangement density of the third conductor segment 204 close to the first end 2040 of the display region 10 is smaller than the arrangement density of the third conductor segment 204 away from the second end 2042 of the display region 10. The second end 2042 of the subsequent third conductor segment 204 is used for bonding connection with other circuit boards and the like. The above-mentioned second end 2042 with smaller wiring density is conducive to subsequent bonding connection.

[0067] In the third fan-out region 18, the length d8 occupied by the first end 2040 of all third conductor segments 204 in the second direction Y can be greater than the length d9 occupied by the second end 2042 of all third conductor segments 204 in the second direction Y. In the third fan-out region 18, the spacing d8 of the first end 2040 of the outermost two third conductor segments 204 in the second direction Y can be greater than the spacing d9 of the second end 2042 of the outermost two third conductor segments 204 in the second direction Y.

[0068] Optionally, as Figure 1As shown, the dimension D1 of the first fan-out area 14 along the first direction X is smaller than the dimension D3 of the third fan-out area 18 along the first direction X. Optionally, the dimension D2 of the second fan-out area 16 along the first direction X is smaller than the dimension D3 of the third fan-out area 18 along the first direction X. After the bending area 11 is subsequently bent, the third fan-out area 18 is located on the non-display side. Although the third fan-out area 18 is larger in size, it will not affect the bezel width; and the design of the larger third fan-out area 18 can make the second end 2042 of the third conductor segment 204 less compact, which is beneficial to the subsequent bonding process.

[0069] Optionally, if at least a portion of the third conductor segment 204 is bow-shaped, it helps to reduce the resistance difference between the third conductor segments 204 in the third fan-out region 18. Specifically, the more bow-shaped portions of the third conductor segments 204 located in the middle region of the third fan-out region 18, and the fewer bow-shaped portions of the third conductor segments 204 located in the regions on opposite sides of the third fan-out region 18 along the second direction, the better to reduce the impedance difference between the third conductor segments 204 in the middle region and the third conductor segments 204 in the side regions of the third fan-out region 18. Furthermore, this design can increase the extension length of the third conductor segment 204 to enhance the stress extension path when the third conductor segment 204 is under force, thereby reducing the stress on the third conductor segment 204.

[0070] Optionally, the resistance of all third conductor segments 204 in the third fan-out region 18 is equal. In this application, as... Figure 3 As shown, multiple first conductor segments 200, multiple second conductor segments 202, multiple third conductor segments 204, and multiple fourth conductor segments 206 are connected in series to form multiple fan-out buses 20. When the total resistance of the first conductor segment 200 and the corresponding second conductor segment 202 is the same, the resistance of each fourth conductor segment 206 in the bending area 11 is the same, and the resistance of each third conductor segment 204 in the third fan-out area 18 is the same, the resistance of each fan-out bus 20 is the same, and the impedance difference between adjacent fan-out buses 20 is small. This can improve the display effect of the display panel and reduce the probability of vertical stripe display defects.

[0071] Optionally, the display area AA includes multiple display signal lines (e.g., data lines, scan lines, etc.) and multiple first DC signal lines (e.g., high DC voltage line VDD, low DC voltage line VSS, etc.), and the display signal lines and the first DC signal lines are electrically connected to the first conductor segment 200; that is, one fan-out bus 20 corresponds to one display signal line or one first DC signal line. Optionally, the first conductor segment 200 electrically connected to the first DC signal line is interspersed within the first conductor segment 200 electrically connected to the display signal line.

[0072] Optionally, the display panel further includes a plurality of second direct-current signal lines arranged along the second direction Y, and the second direct-current signal lines can extend along the first direction X. Optionally, any second direct-current signal line is insulatively arranged with the first conductor segment 200 of the first fan-out area 14 in different layers. Optionally, any second direct-current signal line is insulatively arranged with the second conductor segment 202 of the second fan-out area 16 in different layers. Optionally, any second direct-current signal line is insulatively arranged with the fourth conductor segment 206 of the bending area 11 in the same layer. Optionally, the second direct-current signal line is located in the gap between the third sub-areas 110. Optionally, any second direct-current signal line is insulatively arranged with the third conductor segment 204 of the third fan-out area 18 in different layers. Optionally, the first conductor segment 200 and the first conductor segment 200 are insulatively arranged in the same layer, for example, in the same metal layer. Optionally, the first conductor segment 200 and the fourth conductor segment 206 are insulatively arranged in different layers, for example, in different metal layers.

[0073] As shown in Figure 4 , Figure 4 is a structural schematic diagram of an embodiment of the non-display area wiring in the related art. The first fan-out area 14 and the second fan-out area 16 in the related art are different in height along the first direction X, and the conventional equal-resistance compensation is generally line width compensation or winding compensation; this mode can cause the wiring density on both sides of the second direct-current signal line to be different, resulting in too large impedance difference between the two sides of the direct-current signal line, and further causing vertical vertical stripe display failure. In the present application, the first fan-out area 14 and the second fan-out area 16 are the same or close in height along the first direction X, and the impedance difference between each fan-out bus 20 is small, thereby reducing the impedance difference between the fan-out buses 20 on both sides of the second direct-current signal line, so as to reduce the probability of vertical vertical stripe display failure.

[0074] In one application scenario, please refer to Figure 5 , Figure 5 is a structural schematic diagram of an embodiment of the first fan-out area in Figure 1 . The display area includes a plurality of high direct-current voltage lines VDD (not shown in the figure), a plurality of low direct-current voltage lines VSS (not shown in the figure), and a plurality of data lines; the fan-out bus 20 in the non-display area includes a first power fan-out line 22, a second power fan-out line 24, and a data fan-out line 26, the first power fan-out line 22 is electrically connected with the high direct-current voltage line VDD, the second power fan-out line 24 is electrically connected with the low direct-current voltage line VSS, and the data fan-out line 26 is electrically connected with the data line. Among them, in the first fan-out area 14, the first power fan-out line 22 and the second power fan-out line 24 are alternately arranged, and the same number of data fan-out lines 26 are arranged between adjacent first power fan-out lines 22 and second power fan-out lines 24, and the same number can be one, two, three, etc. The above design can reduce the impedance difference between the data fan-out lines 26 on both sides of the first power fan-out line 22 and the second power fan-out line 24, so as to reduce the probability of vertical vertical stripe display failure.

[0075] Of course, in other embodiments, the arrangement of the plurality of first power fan-out lines 22, the plurality of second power fan-out lines 24 and the plurality of data fan-out lines 26 can be other. For example, please refer to Figure 6 , Figure 6 For Figure 1 the structure of another embodiment of the first fan-out area. In the second direction Y, for the two adjacent first sub-areas 140, in one of the first sub-areas 140, the data fan-out lines 26 and the first power fan-out lines 22 are arranged alternately (as shown in the left first sub-area 140 in Figure 5 , and in the other first sub-area 140, the data fan-out lines 26 and the second power fan-out lines 24 are arranged alternately (as shown in the right first sub-area 140 in Figure 5 ). The above design can also reduce the impedance difference between the data fan-out lines 26 on both sides of the first power fan-out lines 22 and the second power fan-out lines 24, so as to reduce the probability of generating vertical stripe display defects.

[0076] In addition, the first power fan-out lines 22 and the second power fan-out lines 24 in the second DC signal line can cover part of the orthographic projection of the data fan-out lines 26 in the second fan-out area 16 and the third fan-out area 18 on the display panel, but the first power fan-out lines 22 and the second power fan-out lines 24 are located in different metal layers from the data fan-out lines 26 in the second fan-out area 16 and the third fan-out area 18, so as to realize insulation.

[0077] Please refer again to Figure 3 , as shown in Figure 3 , Figure 3 in which M1 represents the first metal layer, and M2 represents the second metal layer M2. The same fan-out bus 20 is located in the same metal layer, and adjacent two fan-out buses 20 are located in different metal layers. Through the above-mentioned different metal layer alternately wiring manner can make the first fan-out area 14, the second fan-out area 16 and the third fan-out area 18 to reduce the width of the frame.

[0078] In another embodiment, as shown in Figure 7 , Figure 7 is an enlarged schematic view of part of the wire segments in the first fan-out area or the second fan-out area or the third fan-out area in Figure 1 . Figure 1 in the first fan-out area 14, the second fan-out area 16 and the third fan-out area 18 (i.e. Figure 3At least one of the first conductor segment 200, the second conductor segment 202, and the third conductor segment 204 includes a first segment 203 and a second segment 208, and the first segment 203 of the same conductor segment is closer to the display area 10 than the second segment 208. The first segment 203 and the second segment 208 of the same conductor segment within the same fan-out area are located in different metal layers, two adjacent first segments 203 within the same fan-out area are located in different metal layers, and two adjacent second segments 208 within the same fan-out area are located in different metal layers. For example, as... Figure 7 As shown, the first conductor segment 200, the second conductor segment 202, or the third conductor segment 204 are segmented. The first segment 203 of the same conductor segment is located in the first metal layer M1, and the second segment 208 is located in the second metal layer M2; or, the first segment 203 of the same conductor segment is located in the second metal layer M2, and the second segment 208 is located in the first metal layer M1. Furthermore, for two adjacent first conductor segments 200 (or second conductor segments 202 or third conductor segments 204), one of the two first segments 203 is located in the first metal layer M1, and the other is located in the second metal layer M2. Similarly, for two adjacent first conductor segments 200 (or second conductor segments 202 or third conductor segments 204), one of the two second segments 208 is located in the second metal layer M2, and the other is located in the first metal layer M1. By alternating traces on different metal layers, the border width occupied by the first fan-out area 14, the second fan-out area 16, and the third fan-out area 18 can be reduced. Furthermore, since the conductor segments located on different metal layers may have different resistance values, the segmented design can further reduce the impedance difference between two adjacent fan-out buses.

[0079] Optionally, in the direction away from the display area 10 (i.e., the first direction X), the vertical height D5 of the first segment 203 and the vertical height D4 of the second segment 208 of the same conductor segment are the same. The above design simplifies the manufacturing process and makes it easier to achieve the same resistance for the first segment 203 and the second segment 208.

[0080] Alternatively, since the first segment 203 and the second segment 208 of the same conductor segment are located in different metal layers, the first segment 203 and the second segment 208 of the same conductor segment are electrically connected through a conductive hole 201; and in the length extension direction of the conductor segment, the conductive hole 201 is located in the middle position of the conductor segment. That is, the extension length of the first segment 203 and the second segment 208 is the same, and this design can reduce the difficulty of process fabrication.

[0081] Alternatively, each fan-out bus 20 includes a line portion located on a different metal layer, and the line portions of the same fan-out bus 20 on different metal layers have the same resistance. This design can reduce the resistance difference between adjacent fan-out buses 20.

[0082] In one application scenario, each first conductive segment 200 in the first fan-out area 14 can adopt a segmented form, the Nth first conductive segment 200 in the first fan-out area 14 adopts an alternating wiring manner of the first metal layer M1 and the second metal layer M2, and the N+1th first conductive segment 200 in the first fan-out area 14 adopts an alternating wiring manner of the second metal layer M2 and the first metal layer M1. The second conductive segment 202 in the second fan-out area 16 and the third conductive segment 204 in the third fan-out area 18 can adopt a non-segmented form, the second conductive segment 202 and the corresponding series-connected third conductive segment 204 can be located in the same metal layer, and the second conductive segments 202 corresponding to adjacent two data line pairs are located in different metal layers. At this time, the second conductive segment 202 and the second segment in the adjacent first conductive segment 200 corresponding to the series connection can be located in the same metal layer or different metal layers, which is not limited in the present application. For example, the first segment 203 of the first conductive segment 200 close to the display area 10 is located in the first metal layer M1, and the second segment 208 is located in the second metal layer M2. The second conductive segment 202 and the third conductive segment 204 corresponding to the series connection of the first conductive segment 200 can be located in the second metal layer M2, or can be located in the first metal layer M1.

[0083] Similarly, each second conductive segment 202 in the second fan-out area 16 can also adopt the similar segmented and arrangement manner, the first conductive segment 200 and the third conductive segment 204 adopt the similar non-segmented and arrangement manner. Alternatively, each third conductive segment 204 in the third fan-out area 18 can also adopt the similar segmented and arrangement manner, the first conductive segment 200 and the second conductive segment 202 adopt the similar non-segmented and arrangement manner.

[0084] In another application scenario, each first wire segment 200 in the first fan-out area 14 can be in a segmented form, the Nth first wire segment 200 in the first fan-out area 14 is routed in an alternating manner with the first metal layer M1 and the second metal layer M2, and the N+1th first wire segment 200 in the first fan-out area 14 is routed in an alternating manner with the second metal layer M2 and the first metal layer M1. Each second wire segment 202 in the second fan-out area 16 can be in a segmented form, the Nth second wire segment 202 in the second fan-out area 16 is routed in an alternating manner with the first metal layer M1 and the second metal layer M2, and the N+1th second wire segment 202 in the second fan-out area 16 is routed in an alternating manner with the second metal layer M2 and the first metal layer M1. Each third wire segment 204 in the third fan-out area 18 can be in a segmented form, the Nth third wire segment 204 in the third fan-out area 18 is routed in an alternating manner with the second metal layer M2 and the first metal layer M1, and the N+1th third wire segment 204 in the third fan-out area 18 is routed in an alternating manner with the first metal layer M1 and the second metal layer M2.
