[0036] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0037] It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a system, product, or device comprising a series of units is not necessarily limited to those steps or units explicitly listed, but may include other units that are not explicitly listed or that are inherent to these products or devices.

[0038] Figure 1 is a structural diagram of a display panel provided by an embodiment of the present invention, Figure 2 is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a display panel 10, which includes a display area 100; the display area 100 includes an overlapping heating area 110 and a separate heating area 120, and the overlapping heating area 110 is located between two adjacent separate heating areas 120; the display panel 10 also includes a plurality of heating lines 200 located in the display area 100, the heating lines 200 include a first heating line 210 and a second heating line 220; the separate heating area 120 includes a first heating area 121 and a second heating area 122, Along the thickness direction of the display panel 10, the first heating line 210 is located in the first heating zone 121 and the overlapping heating zone 110, and the second heating line 220 is located in the second heating zone 122 and the overlapping heating zone 110; wherein, the step density of the heating line 200 in the first heating zone 121 is the first density, the step density of the heating line 200 in the second heating zone 122 is the second density, and the step density of the heating line 200 in the overlapping heating zone 110 is the third density; the first density is equal to the second density and equal to the third density.

[0039] The display panel 10 includes a display area 100, which is used to implement the display function of the display panel 10. Furthermore, the display panel 10 also includes a heating line 200, which can provide a certain amount of heat to the display panel 10 to ensure that the display panel 10 maintains normal display operation in extreme environments such as cold. The heating line 200 is at least partially located in the display area and includes a first heating line 210 and a second heating line 220. Furthermore, the display panel 10 further divides the display area 100 according to the location of the heating line 200.

[0040] Specifically, the display area 100 includes an overlapping heating area 110 and a separate heating area 120. The separate heating area 120 includes a first heating area 121 and a second heating area 122. The first heating line 210 is located in the first heating area 121 and the overlapping heating area 110, and the second heating line 220 is located in the second heating area 122 and the overlapping heating area 110. It can be seen that the overlapping heating area 110 is distributed with both the first heating line 210 and the second heating line 220, while the separate heating area 120 is distributed with only one type of heating line 200: the first heating area 121 is distributed with the first heating line 210, and the second heating area 122 is distributed with the second heating line 220.

[0041] Furthermore, different heating traces 200 may have different heating states, such as different heating voltages on the heating traces 200, or the operating state of the driving transistor of the display area 100 where the heating traces 200 are located, which will all result in heating differences. The overlapping heating zone 110 includes both the first heating trace 210 and the second heating trace 220, that is, the overlapping heating zone 110 is the junction of the first heating zone 121 and the second heating zone 122. In order to avoid a large difference in heat between the overlapping heating zone 110 and the individual heating zone 120 due to the difference between the first heating zone trace 210 and the second heating zone trace 220 in the overlapping heating zone 110, the arrangement of the heating traces 200 in each heating zone can be adjusted.

[0042] Specifically, the distribution density of the first heating lines 210 in the first heating zone 121 is equal to the distribution density of the second heating lines 220 in the second heating zone 122, and is also equal to the distribution density of the overall heating lines 200 of the first heating lines 210 and the second heating lines 220 in the overlapping heating zone 110. The distribution density may include the same number of heating lines 200 in each zone, or the same spacing between heating lines 200 per unit zone. In other words, by adjusting the distribution density of the heating lines 200 in the overlapping heating zone 110 and the individual heating zones 120, the difference in heat generated by the different heating lines 200 in the overlapping heating zone 110 can be balanced, ensuring that the difference in heat generated by the overlapping heating zone 110 and any individual heating zone 120 is not significant, thereby achieving a balanced heating effect for the entire display panel 10. In other words, when there may be heating differences between the first heating line 210 and the second heating line 220, adjusting the distribution density of the heating lines 200 in each area to be the same can avoid sudden changes in the overlapping heating area 210, thereby ensuring the overall heating uniformity of the display panel 10 and ensuring the display effect of the display panel 10.

[0043] In summary, the display panel provided by the embodiment of the present invention has a separate heating zone including a first heating zone and a second heating zone, and the distribution density of the heating lines in the first heating zone, the second heating zone and the overlapping heating zone is the same, that is, when there is a difference in heat between different separate heating zones, sudden changes in the overlapping heating zone can be avoided, thereby ensuring the overall heating uniformity of the display panel and the display effect of the display panel.

[0044] Continue to refer Figure 1 and Figure 2 As shown, in the separate heating zone 120 , the distance between two adjacent heating lines 200 is L1 ; in the overlapping heating zone 110 , the distance between adjacent heating lines 200 is L2 ; wherein, L1 = L2 .

[0045] Furthermore, the distance between two adjacent heating lines 200 in the individual heating zone 120 is L1, that is, Figure 1 As shown, the distance between two adjacent first heating lines 210 in the first heating zone 121 is L1. Figure 2 As shown, the distance between two adjacent second heating lines 220 in the second heating zone 122 is also L2, that is, the distance between two adjacent heating lines 200 in the first heating zone 121 is the same as the distance between two adjacent heating lines 20 in the second heating zone 122, further ensuring that the heating effects of the first heating zone 121 and the second heating zone 122 are balanced.

[0046] In the overlapping heating zone 110, the spacing between adjacent heating lines 200 is L2, and L2 = L1, that is, the spacing between the heating lines 200 in the overlapping heating zone 110 and the spacing between the heating lines 200 in the individual heating zones 120 are equal, thereby ensuring that the heating effects of the overlapping heating zone 110 and the individual heating lines 120 are balanced, thereby ensuring the display effect of the display panel 10. It should be noted that in the overlapping heating zone 110, there are first heating lines 210 and second heating lines 220, and there are cases where adjacent heating lines 200 are different. Figure 1 and Figure 2 As shown, adjacent heating lines 200 are first heating lines 210 and second heating lines 220, and the spacing between them is L2. There are also cases where adjacent heating lines 200 are the same, for example, if adjacent heating lines 200 are all first heating lines 210, the spacing between adjacent first heating lines 210 is L2, or if adjacent heating lines 200 are all second heating lines 220, the spacing between adjacent second heating lines 220 is L2. The embodiment of the present invention does not specifically limit this. The heating lines 200 are evenly arranged on the entire display panel 10, ensuring a balanced heating effect for the display panel 10. The evenly arranged heating lines 200 also facilitate preparation and reduce preparation costs.

[0047] Continue to refer Figure 1 and Figure 2 As shown, in the overlapping heating area 110 , a second heating line 220 is disposed between two adjacent first heating lines 210 ; and / or a first heating line 210 is disposed between two adjacent second heating lines 220 .

[0048] Among them, reference Figure 1 and Figure 2 As shown, while ensuring that the distribution density of the heating lines 200 in the overlapping heating zone 110 and the separate heating zone 120 is the same, the first heating lines 210 and / or the second heating lines 220 in the overlapping heating zone 110 can be arranged alternately, thereby ensuring that the heating effects of the first heating lines 210 and the second heating lines 220 on the overlapping heating zone 110 are balanced.

[0049] Furthermore, based on the extension and arrangement direction of the heating lines 200, there are differences in the overlapping arrangement of the heating lines 200 in the overlapping heating zone 110. Figure 1As shown, the extension direction of the heating line 200 is consistent with the direction from the single heating zone 120 to the overlapping heating zone 110. In this case, the heating line 200 of the overlapping heating zone 110 extends from the single heating zone 120 to the overlapping heating zone 110, that is, the first heating line 210 alternately arranged in the overlapping heating zone 110 comes from the first heating zone 121, and the second heating line comes from the second heating zone 122. Figure 2 As shown, the extension direction of the heating line 200 is perpendicular to the direction from the individual heating zone 120 to the overlapping heating zone 110. In this case, the heating line 200 of the overlapping heating zone 110 is aligned with the heating line 200 in the individual heating zone 120 but is not extended.

[0050] Furthermore, the first heating lines 210 and the second heating lines 220 in the overlapping heating zone 110 are alternately arranged to balance the differences in heating effects of the different heating lines 200. Specifically, when the heating lines 200 are alternately arranged, the number of second heating lines 220 between two adjacent first heating lines 210 can be adjusted, or the number of first heating lines 210 between two adjacent second heating lines 220 can be adjusted. In other words, the distribution of the heating lines 200 can be adjusted more meticulously, thereby better ensuring the overall heating effect of the display panel 10 and the display effect of the display panel 10.

[0051] Figure 3 is a schematic structural diagram of another display panel provided by an embodiment of the present invention. Figure 4 is a schematic structural diagram of another display panel provided by an embodiment of the present invention. Figure 5 is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Figures 3 to 5 As shown, in the overlapping heating area 110, n second heating lines 220 are arranged between any two adjacent first heating lines 210; or, m first heating lines 210 are arranged between any two adjacent second heating lines 220, where n and m are both positive integers.

[0052] The first heating lines 210 and the second heating lines 220 in the overlapping heating zone 110 can be alternately and evenly arranged. Figure 3 As shown, in the overlapping heating area 110, there is a second heating line 220 between each adjacent first heating line 210, and there is a first heating line 210 between each adjacent second heating line 220. Figure 4 As shown, there are two second heating lines 220 between two adjacent first heating lines 210. Figure 5As shown, there are two first heating lines 210 between any two adjacent second heating lines 220. That is, n second heating lines 220 are provided between any two adjacent first heating lines 210; or, m first heating lines 210 are provided between any two adjacent second heating lines 220, where n and m are both positive integers. The specific values ​​of m and n can be further determined by various factors such as the heating voltages in the first heating lines 210 and the second heating lines 220, and the embodiments of the present invention do not limit these specific values.

[0053] Figure 6 is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Figure 6 As shown, in the overlapping heating zone 110, a first gap is formed between two adjacent first heating lines 210, there is a first gap of a first width S1 and a first gap of a second width S2, the first width S1 is greater than the second width S2, the first gap of the first width S1 is located at the first gap of the second width S2 and is away from the center Q of the overlapping heating zone 110; in the overlapping heating zone 110, a second gap is formed between two adjacent second heating lines 220, there is a second gap of a third width S3 and a second gap of a fourth width S4, the third width S is greater than the fourth width S4, the second gap of the third width S3 is located at the second gap of the fourth width S4 and is away from the center Q2 of the overlapping heating zone 110.

[0054] The first heating lines 210 and the second heating lines 220 in the overlapping heating zone 110 can be alternately and gradually arranged. Figure 6 As shown, there is a first gap of different widths between two adjacent first heating traces 210, and a second gap of different widths between two adjacent second heating traces 220. Specifically, the first gap includes a first width S1 and a second width S2, and the second gap includes a third width S3 and a fourth width S4, wherein the first width S1 is greater than the second width S2, and the third width S3 is greater than the fourth width S4.

[0055] Among them, the first gap of the first width S1 is located at the first gap of the second width S2 and is far away from the center Q of the overlapping heating zone 110, that is, the first gap width away from the center of the overlapping heating zone 110 increases, that is, the two adjacent first heating lines 210 are approximately close to the center of the overlapping heating zone 110, and the arrangement density is approximately small. Similarly, the second gap of the third width S3 is located at the second gap of the fourth width S4 and is far away from the center Q of the overlapping heating zone 110, that is, the second gap width away from the center of the overlapping heating zone 110 increases, that is, the two adjacent second heating lines 220 are approximately close to the center of the overlapping heating zone 110, and the arrangement density is approximately small. The embodiment of the present invention does not limit this specific gap value. Figure 6For example, in the overlapping heating zone 110, there is a difference in the distance between the central area and the edge area and the separate heating zone 120, and thus there is a difference in the heat of the first heating line 210 and the second heating line 220 in the central area and the edge area. By gradually setting the alternation between the heating lines 200 in the overlapping heating zone 110, it can be ensured that the transition from the separate heating zone 120 to the overlapping heating zone 110 is smoother, thereby ensuring the overall heating effect of the display panel 10, and thereby ensuring the display effect of the display panel 10.

[0056] Figure 7 is a schematic structural diagram of another display panel provided by an embodiment of the present invention. Figure 8 is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Figure 7 and Figure 8 As shown, the display panel 10 also includes a non-display area 300, which is located on one side of the display area 100; the center Q of the overlapping heating area 110 and the center P of the separate heating area 120 are arranged along the first direction X; wherein the second direction Y is the direction from the display area 100 to the non-display area 300, and the second direction Y intersects with the first direction X and is parallel to the plane where the heating line 200 is located.

[0057] The display panel 10 further includes a non-display area 300, which may be a border region located to one side of the display area 100. The embodiment of the present invention does not specifically limit the positional relationship between the display area 100 and the non-display area 300. The display area 100 is used to implement the display function of the display panel 10, while the non-display area 300 is used to house a driver unit, etc., for driving the display area 100 to implement the display function.

[0058] For further reference, Figure 7 and Figure 8 As shown, the direction from the display area 100 to the non-display area 200 is the second direction Y, and the direction from the center Q of the overlapping heating area 110 to the center P of the individual heating area 120 is the first direction X. The first direction X and the second direction Y are perpendicular to each other. The display panel 10 is formed by fabricating multiple different film layers on a substrate. The definition of the first direction X and the second direction Y facilitates the subsequent enumeration of different extension and arrangement methods of the heating traces 200.

[0059] Continue to refer Figure 8 As shown, the first heating line 210 and the second heating line 220 are arranged along the first direction X, and the first heating line 210 and the second heating line 220 extend along the second direction Y.

[0060] Specifically, refer to Figure 8As shown, the extension direction of the first heating line 210 and the second heating line 220 is consistent with the direction from the display area 100 to the non-display area 300, that is, an arrangement method of the heating lines 200 is provided.

[0061] For further reference, Figure 8 As shown, the non-display area 300 includes a driver chip setting area 310; the first heating line 210 includes at least two groups of first heating line groups 211, the first heating line group 211 includes a first line group 211A and a second line group 211B; the first line group 211A includes a plurality of first lines 211A1, the length of the first line 211A1 is q1, and the first line 211A1 includes a first end N1 close to the driver chip setting area 310; the second line group 211B includes a plurality of second lines 211B1, the length of the second line 211B1 is q2, and the second line 211B1 includes a second end N2 close to the driver chip setting area 310, and the first end N1 is located on the side of the second end N2 close to the driver chip setting area 310; The heating line 220 includes at least two groups of second heating line groups 221, the second heating line group 221 includes a third line group 221A and a fourth line group 221B; the third line group 221A includes multiple third lines 221A1, the length of the third line 221A1 is q3, and the third line 221A1 includes a third end N3 close to the driver chip setting area 310; the fourth line group 221B includes multiple fourth lines 221B1, the length of the fourth line 221B1 is q4, and the fourth line 221B1 includes a fourth end N4 close to the driver chip setting area 310, and the third end N3 is located on the side of the fourth end N4 close to the driver chip setting area 310; wherein, q1>q2, q3>q4, q1, q2, q3 and q4 are positive numbers.

[0062] The non-display area 300 includes a driver chip installation area 310. The driver chip installation area 310 can drive multiple sub-pixels (not specifically shown in the figure) in the display area 100, thereby realizing the display function of the display panel 10. However, the driver chip installation area 310 will generate some heat after the display panel 10 displays and operates for a period of time. Based on this situation, the heating traces 200 can be further regulated in detail to fully utilize the heat, better ensure the heating effect of the display panel 10, and thus ensure the display effect of the display panel 10.

[0063] Specifically, the first heating line 210 includes at least two groups of first heating line groups 211. Specifically, refer to Figure 8As shown, the first heating line group 211 includes a first line group 211A and a second line group 211B. The first line group 211A includes a first line 211A1, and the end of the first line 211A1 close to the driver chip setting area 310 is the first end N1; the second line group 211B includes a second line 211B1, and the end of the second line 211B1 close to the driver chip setting area 310 is the second end N2; the first end N1 is located on the side of the second end N2 close to the driver chip setting area 310. At the same time, the length of the first line 211A1 is greater than the length of the second line 211B1. Generally speaking, the length of the heating line 200 located in the first line group 211A is greater than the length of the heating line 200 located in the second line area 211B. At the same time, the heating line 200 in the first line group 211A is closer to the driver chip setting area 310 than the heating line 200 in the second line area 211B.

[0064] Similarly, the second heating line 220 includes at least two groups of second heating line groups 221. For details, refer to Figure 8 As shown, the second heating trace group 221 includes a third trace group 221A and a fourth trace group 221B. The third trace group 221A includes a third trace 221A1, with the end of the third trace 221A1 near the driver chip setting area 310 being the third end N3. The fourth trace group 221B includes a fourth trace 221B1, with the end of the fourth trace 221B1 near the driver chip setting area 310 being the fourth end N4. The third end N3 is located on the side of the fourth end N4 near the driver chip setting area 310. Furthermore, the length of the third trace 221A1 is greater than that of the fourth trace 221B1. In general, the length of the heating trace 200 located in the third trace group 221A is greater than the length of the heating trace 200 located in the fourth trace area 221B. Furthermore, the heating trace 200 in the third trace group 221A is closer to the driver chip setting area 310 than the heating trace 200 in the fourth trace area 221B.

[0065] In general, whether it is a single heating zone 120 or an overlapping heating zone 110, the heating lines 200 close to the driver chip setting area 310 are only the first lines 211A1 and / or the third lines 221A1, while the heating lines 200 away from the driver chip setting area 310 have the second lines 211B1 and / or the fourth lines 221B1 in addition to the first lines 211A1 and / or the third lines 221A1, that is, the distribution density of the heating lines 200 close to the driver chip setting area 310 is less than the distribution density of the heating lines 200 away from the driver chip setting area 310. In the actual operation of the display panel 10, the display area 100 close to the driver chip setting area 310 can be heated by the heat generated by the driver chip setting area 310, thereby reducing the setting of its heating lines 200. However, along the first direction X, the distribution density of the heating lines 200 in the overlapping heating area 110 and the individual heating area 120 can still be kept the same, further ensuring heating uniformity of the display panel 10 and ensuring the display effect of the display panel 10 .

[0066] Figure 9 is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Figure 9 As shown, the second routing group 211B also includes multiple first virtual routings 213, which are located on the side of the second routing 211B1 close to the driver chip setting area 310; the fourth routing group 221B also includes multiple second virtual routings 223, which are located on the side of the fourth routing 221B1 close to the driver chip setting area 310.

[0067] For further reference, Figure 9 As shown, the second routing group 211B also includes multiple first virtual routings 213, and the fourth routing group 221B also includes multiple second virtual routings 223. By setting virtual routings, the length of the short area of ​​the heating routing 200 can be further compensated, that is, by setting virtual routings, the heating routing 200 setting area is arranged in a balanced manner on the whole, ensuring that the density of routing settings in different areas is balanced, thereby avoiding different light reflectances in different areas of the display panel 10 due to uneven routing settings, and avoiding uneven display effects of the display panel 10.

[0068] Specifically, the first virtual routing 213 is located on a side of the second routing 211B1 close to the driver chip setting area 310, and the second virtual routing 223 is located on a side of the fourth routing 221B1 close to the driver chip setting area 310. By adding the length of the first virtual routing 213 to the length of the second routing 211B1, the length is close to the length of the first routing 211A1. By adding the length of the second virtual routing 233 to the length of the fourth routing 221B1, the length is close to the length of the third routing 221A1.

[0069] Furthermore, the first virtual wiring 213 and the second virtual wiring 223 can be insulated from the heating wiring 200, and the first virtual wiring 213 and the second virtual wiring 223 are electrically connected to the fixed potential signal terminal. The virtual wiring is insulated from the heating wiring 200, so as to avoid the virtual wiring interfering with the signal transmitted in the heating wiring 200. Furthermore, in order to avoid inducing other signals that affect the normal transmission of the display signal when the virtual wiring is floating, the potential of the virtual wiring can be adjusted, for example, the virtual wiring is electrically connected to the fixed potential end. In this way, on the one hand, a fixed potential signal is transmitted on the virtual wiring, and the potential will not be affected by other signals and will not interfere with other signals; on the other hand, when the virtual wiring is electrically connected to the fixed potential end, the resistance loss in the signal transmission process in the fixed signal end wiring can be reduced, thereby improving the signal transmission effect in the display panel.

[0070] Continue to refer Figure 7 As shown, the first heating line 210 and the second heating line 220 extend along the first direction X, and the first heating line 210 and the second heating line 220 are arranged along the second direction Y.

[0071] Specifically, refer to Figure 7 As shown, the extension direction of the first heating line 210 and the second heating line 220 is perpendicular to the direction from the display area 100 to the non-display area 300, which provides another arrangement of the heating lines 200.

[0072] For further reference, Figure 7As shown, the non-display area 300 includes a driver chip setting area 310; the first heating line 210 includes at least two groups of fifth heating line groups 215, the fifth heating line group 215 includes a fifth line group 215A and a sixth line group 215B; the fifth line group includes p1 fifth lines 215A1, the distance between two adjacent fifth lines is M1, and the distance between the fifth line 215A1 close to the driver chip setting area 310 and the driver chip setting area 130 is a1; the sixth line group 215B includes p2 sixth lines 215B1, the distance between two adjacent sixth lines 215B1 is M2, and the distance between the sixth line 215B1 close to the driver chip setting area 130 and the driver chip setting area 130 is a2; wherein p1>p2, p1 and p2 are positive integers; M1=M2, M1 and M2 are positive numbers, a1<a2, a1 and a2 are positive numbers; the second heating routing 220 includes at least two groups of second heating routing groups 225, the second heating routing group 225 includes a seventh routing group 225A and an eighth routing group 225B; the seventh routing group 225A includes p3 seventh routing lines 225A1, the distance between two adjacent seventh routing lines 225A1 is M3, and the distance between the seventh routing line 225A1 close to the driver chip setting area 130 and the driver chip setting area 130 is a3; the eighth routing group 225B includes p4 eighth routing lines 225B1, the distance between two adjacent eighth routing lines 225B1 is M4, and the distance between the eighth routing line 225B1 close to the driver chip setting area 130 and the driver chip setting area 130 is a4; wherein p3>p4, p3 and p4 are positive integers; M3=M4, M3 and M4 are positive numbers, a3<a4, a3 and a4 are positive numbers.

[0073] The non-display area 300 includes a driver chip installation area 310. The driver chip installation area 310 can drive multiple sub-pixels (not specifically shown in the figure) in the display area 100, thereby realizing the display function of the display panel 10. However, the driver chip installation area 310 will generate some heat after the display panel 10 displays and operates for a period of time. Based on this situation, the heating traces 200 can be further regulated in detail to fully utilize the heat, better ensure the heating effect of the display panel 10, and thus ensure the display effect of the display panel 10.

[0074] Specifically, the first heating line 210 includes at least two groups of fifth heating line groups 215. Specifically, refer to Figure 7As shown, the fifth heating line group 215 includes a fifth line group 215A and a sixth line group 215B. The fifth line group 215A includes p1 fifth lines 215A1, and the distance between the fifth line 215A near the driver chip setting area 310 and the driver chip setting area 130 is a1. The sixth line group 215B includes p2 sixth lines 215B, and the distance between the sixth line 215AB near the driver chip setting area 310 and the driver chip setting area 130 is a2. In general, the number of fifth lines 215A1 in the fifth line group 215A is greater than the number of sixth lines 215B in the sixth line group 215B. At the same time, the heating lines 200 in the fifth line group 215A are closer to the driver chip setting area 310 than the heating lines 200 in the sixth line group 215B.

[0075] The second heating line 220 includes at least two groups of sixth heating line groups 225. Figure 7 As shown, the sixth heating line group 225 includes a seventh line group 225A and an eighth line group 225B. The seventh line group 225A1 includes p3 seventh lines 225A1, and the seventh lines 225A1 near the driver chip setting area 310 are at a distance a3 from the driver chip setting area 130. The eighth line group 225B includes p4 eighth lines 225B1, and the eighth lines 225B1 near the driver chip setting area 310 are at a distance a4 from the driver chip setting area 130. In general, the number of seventh lines 225A1 in the seventh line group 225A is greater than the number of eighth lines 225B1 in the eighth line group 225B. Furthermore, the heating lines 200 in the seventh line 225A1 are closer to the driver chip setting area 310 than the heating lines 200 in the eighth line 225B1.

[0076] Generally speaking, whether in the individual heating zones 120 or the overlapping heating zones 110, the number of heating traces 200 near the driver chip setting zone 310 is less than the number of heating traces 200 far from the driver chip setting zone 310. That is, the distribution density of the heating traces 200 near the driver chip setting zone 310 is less than the distribution density of the heating traces 200 far from the driver chip setting zone 310. During actual operation of the display panel 10, the display area 100 near the driver chip setting zone 310 can be heated by the heat generated by the driver chip setting zone 310, thereby reducing the number of heating traces 200 there. However, along the first direction X, the distribution density of the heating traces 200 in the overlapping heating zone 110 and the individual heating zone 120 can still be maintained to be the same, further ensuring the heating uniformity of the display panel 10 and the display effect of the display panel 10.

[0077] Figure 10is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Figure 10 As shown, the sixth routing group 215B also includes multiple third virtual routings 217, which are located on the side of the sixth routing 215B1 close to the driver chip setting area 130; the eighth routing group 225B also includes multiple fourth virtual routings 227, which are located on the side of the eighth routing 225B1 close to the driver chip setting area 130.

[0078] For further reference, Figure 10 As shown, the sixth routing group 215B also includes multiple third virtual routings 217, and the eighth routing group 225B also includes multiple fourth virtual routings 227. By setting virtual routings, the area with a small number of heating routings 200 can be further compensated in terms of quantity, that is, by setting virtual routings, the heating routing 200 setting area can be arranged in a balanced manner as a whole, ensuring that the density of routing settings in different areas is balanced, thereby avoiding different light reflectances in different areas of the display panel 10 due to uneven routing settings, and avoiding uneven display effects of the display panel 10.

[0079] Specifically, the third virtual routing 217 is located on the side of the sixth routing 215B1 close to the driver chip setting area 130, and the fourth virtual routing 227 is located on the side of the eighth routing 225B1 close to the driver chip setting area 130. By adding the number of the third virtual routing 217 and the fifth routing 215A1, the overall number is close to the seventh routing 225A1. By adding the number of the fourth virtual routing 227 and the eighth routing 225B1, the overall number is close to the seventh routing 225A1.

[0081] Specifically, refer to Figure 11As shown, the first heating lines 210 and the second heating lines 220 can extend in the same direction as the direction from the display area 100 to the non-display area 300. At the same time, the first heating lines 210 and the second heating lines 220 can extend in a direction perpendicular to the direction from the display area 100 to the non-display area 300. This means that the first heating lines 210 and the second heating lines 220 are arranged in a crisscross pattern. This provides another arrangement for the heating lines 200. The display panel 10 provides a variety of arrangements for the heating lines 200, and thus, the display panel 10 also provides a variety of arrangements.

[0083] Among them, reference Figure 12 As shown, the display panel 10 includes a plurality of sub-pixels 400 in the display area 100. The display function of the display panel 10 is achieved by controlling the light emission of the sub-pixels 400. Specifically, the sub-pixels 400 include a light-transmitting area and a wiring area.

To ensure a balanced heating effect at different sub-pixels 400P, that is, to ensure consistency in the effect of the heating wiring 200 on them, the first heating wiring 210 and the second heating wiring 220 should be arranged in the same position relative to the sub-pixel 400.

[0086] Exemplary, reference Figure 13 and Figure 14 As shown, the first heating line 210 is at least partially located in the first sub-pixel setting area 410, and the second heating line 220 is similar.

While ensuring that the overall heating traces 200 are evenly distributed, the number of heating traces 200 may be adaptively adjusted, thereby reducing wiring costs while providing space for other traces of the display panel 10. This is not specifically limited in the embodiments of the present invention.

[0095] Figure 19 yes Figure 18 A schematic diagram of a cross-sectional structure along the section line B-B', Figure 20 yes Figure 18 Another cross-sectional structure diagram along the section line BB', refer to Figure 19 and Figure 20 As shown, the display panel 10 includes an array substrate 500 , a color filter substrate 600 and a liquid crystal layer 700 located between the array substrate 500 and the color filter substrate 600 ; the heating traces 200 are arranged in the array substrate 500 and / or the color filter substrate 500 .

[0096] Specifically, the display panel 10 may be a liquid crystal display panel and includes an array substrate 500, a liquid crystal layer 700, and a color filter substrate 600, wherein the liquid crystal layer 700 is located between the array substrate 500 and the color filter substrate 600. The array substrate 500 drives the liquid crystals in the liquid crystal layer 700 to deflect, and in combination with the color filter substrate 600, the display panel 10 realizes color display.

[0097] The array substrate 500 and the color filter substrate 600 may include multiple layers. Figure 19 As shown, the heating line 200 is placed on the array substrate 500. Further, the heating line 200 can be set on the array substrate 500.

Furthermore, the heating traces 200 can also be placed in the film layer of the color filter substrate 600. By reusing the existing film layer as the heating traces 200, the overall film layer of the display panel 10 can be reduced, thereby ensuring the heating effect while also facilitating a thin design of the display panel 10.
