[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. It should be noted that the sizes and shapes of the figures in the drawings do not reflect the actual proportions, and the purpose is only to illustrate the contents of the present invention. And the same or similar numbers throughout represent the same or similar elements or elements with the same or similar functions. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described 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.

[0044] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning understood by persons of ordinary skill in the field to which the invention belongs. The words "first", "second" and similar terms used in the specification and claims of the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "include" or "comprise" mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Inside", "outside", "upper", "lower" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0045] As used herein, "about" or "approximately the same" is inclusive of the stated value and means within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, "approximately the same" can mean that the difference relative to the stated value is within one or more standard deviations, or within ±30%, 20%, 10%, 5%.

[0046] In the accompanying drawings, the thickness of layers, films, panels, regions, etc. are exaggerated for clarity. Exemplary embodiments are described herein with reference to cross-sectional views that are schematic representations of idealized embodiments. As such, deviations from the shapes of the figures are to be expected as a result of, for example, manufacturing techniques and / or tolerances. Thus, the embodiments described herein should not be construed as limited to the specific shapes of the regions as shown herein, but rather include deviations in shape that result from, for example, manufacturing. For example, a region illustrated or described as flat may typically have rough and / or nonlinear features. Furthermore, sharp corners illustrated may be rounded. Thus, the regions illustrated in the figures are schematic in nature, and their shapes are not intended to illustrate the precise shape of the regions and are not intended to limit the scope of the claims.

[0047] In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of known functions and known components.

[0048] TFT-LCDs have certain drawbacks. For example, the operating temperature of common liquid crystal materials ranges from -30°C to 80°C. Temperatures too low cause the liquid crystal to solidify, preventing proper deflection when voltage is applied. Furthermore, at ultra-low temperatures, the electron mobility of amorphous silicon (A-Si) decreases, reducing the on-state current (Ion) of the TFT device, preventing it from fully turning on. These two factors limit the use of TFT-LCDs in ultra-low temperature environments. To address these issues in low-temperature environments, in-box heating technology has been developed. This technology utilizes the thermal effect of current to heat the display panel, raising its temperature above the ambient temperature and ensuring proper operation. However, the introduction of in-box heating signal lines interferes with existing metal signal lines, affecting the display panel's performance. Furthermore, the overlap of the heating signal lines with the existing metal signal lines results in low UV transmittance after the display panel is assembled, preventing the frame sealant from curing properly.

[0049] In view of this, an embodiment of the present disclosure provides an array substrate, as shown in Figures 1, 2A-2D, and 3-6, wherein Figure 1 is one of the schematic top views of the array substrate provided in an embodiment of the present disclosure, Figure 2A is an enlarged schematic view of the dotted line frame S1 in Figure 1, Figure 2B is a schematic view of a single film layer of the first common electrode portion in Figure 2A, Figure 2C is a schematic view of a single film layer of the second heating trace in Figure 2A, Figure 2D is an enlarged schematic view of a heating winding unit P in Figure 2A, Figure 3 is an enlarged schematic view of the dotted line frame S2 in Figure 1, Figure 4 is an enlarged schematic view of the dotted line frame S3 in Figure 1, Figure 5 is a schematic cross-sectional view of the side where the first terminal group is located, and Figure 6 is a schematic cross-sectional view of the side where the second terminal group is located, comprising a display area AA and a non-display area BB located outside the display area AA, wherein:

[0050] Substrate 1;

[0051] A plurality of data lines (not shown in the figure) are located on one side of the substrate 1 and extend along the first direction X. Specifically, the data lines may be located in the display area AA.

[0052] A plurality of first heating traces 3 are located on the same side of the substrate 1 as the data lines, and at least one heating trace 3 among the plurality of heating traces 3 includes: a first heating trace portion 31 located in the display area AA, and a second heating trace portion 32 located in the non-display area BB;

[0053] A first terminal group D1 is located in the non-display area BB; the first terminal group D1 includes: a plurality of first terminals D10 arranged in sequence along the second direction Y; the plurality of first terminals D10 are electrically connected to a plurality of data lines; specifically, the array substrate may further include data connection lines located in the non-display area BB, and the data lines may be electrically connected to the first terminals D10 via the data connection lines;

[0054] The second terminal group D2 is located in the non-display area BB and is located on a different side of the display area AA than the first terminal group D1. Specifically, for example, as shown in FIG1 , the first terminal group D1 may be located on the lower side of the display area AA, and the second terminal group D2 may be located on the upper side of the display area AA. The second terminal group D2 includes: a plurality of second binding terminals D20 arranged in sequence along the second direction Y; the plurality of second terminals D20 are electrically connected to the plurality of first heating wires 3 via the second heating wiring portion 32;

[0055] The common electrode 4 includes: a first common electrode portion 41 located in the non-display area BB, the first common electrode portion 41 and the second terminal group D2 are located on the same side of the display area AA. For example, as shown in Figure 1, the first common electrode portion 41 is also located on the upper side of the display area AA; and the orthographic projection of the first common electrode portion 41 on the substrate 1 has an overlapping area with the orthographic projection of the second heating wiring portion 32 on the substrate 1.

[0056] In the embodiment of the present disclosure, the second terminal group D2 electrically connected to the first heating line 3 and the first terminal group D1 electrically connected to the data line are respectively located on different sides of the display area AA, and a double-sided design of different terminal groups is adopted to avoid the overlap of the first heating line 3 and the data connection line in the non-display area BB, reduce the overlapping area between the two, reduce the probability of capacitive coupling between the two, and thus reduce the signal coupling when the display panel is working, avoiding the picture abnormality caused by capacitive coupling; moreover, the orthographic projection of the first common electrode portion 41 on the substrate 1 and the orthographic projection of the second heating wiring portion 32 on the substrate 1 are There is an overlapping area, that is, the projections of the first common electrode portion 41 and the second heating wiring portion 32 are overlapped, to avoid the problem that when the two do not overlap at all, the area occupied by the metal in the non-display area is larger, and when the frame sealant in the non-display area is heated and cured by ultraviolet light irradiation, the ultraviolet light transmittance is low due to the metal blocking, resulting in poor heating and curing effect of the frame sealant; moreover, the second heating wiring portion 32 in the non-display area BB is directly connected to the first heating wiring portion 31 in the display area AA, without peripheral wiring, directly avoiding the problem of peripheral overheating and poor heating effect in the display area.

[0057] In-liquid crystal cell heating is to add a layer of heating wire signal line in the array substrate of the display panel. When the temperature is lower than the set temperature, a certain voltage is applied to the heating wire, and the display panel is heated due to the thermal effect of the current. According to the thermal effect formula Q = I 2 RT can be obtained. To ensure the heating effect of the display area and reduce the heat loss of the peripheral metal wires, it is necessary to ensure that the resistance of the display area is small enough and the resistance of the peripheral wiring is large enough during design.

[0058] In a possible embodiment, in combination with Figures 2A to 2D, Figures 3, 5 and 6, the pattern shape of at least a portion of the first common electrode portion 41 is the same as the pattern shape of at least a portion of the second heating trace portion 32, and the orthographic projection of at least a portion of the first common electrode portion 41 on the substrate 1 coincides with the orthographic projection of at least a portion of the second heating trace portion 32 on the substrate 1. Specifically, the pattern shape of all the first common electrode portions 41 may be the same as the pattern shape of all the second heating trace portions 32, and the orthographic projection of all the first common electrode portions 41 on the substrate 1 coincides with the orthographic projection of all the second heating trace portions 32 on the substrate 1. In the embodiment of the present disclosure, making the pattern shape of the first common electrode portion 41 and the second heating trace portion 32 the same and their orthographic projections coincide can avoid the problem that the area occupied by the two in the non-display area is large, and when the frame sealant in the non-display area is heated and cured by ultraviolet light irradiation, the ultraviolet light transmittance is low due to metal obstruction, resulting in poor heating and curing effect of the frame sealant.

[0059] In a possible embodiment, in combination with Figures 2A-2D, Figure 3, Figure 5 and Figure 6, the second heating wiring portion 32 includes: a first sub-heating wiring portion 321; the first sub-heating wiring portion 321 includes: a plurality of heating winding units P arranged in sequence along the first direction X, and the plurality of heating winding units P are connected in sequence; the first common electrode portion 41 includes: a first sub-common electrode portion 411; the first sub-common electrode portion 411 includes: a plurality of common winding units Q arranged in sequence along the first direction X, and the plurality of common winding units Q are connected in sequence; the orthographic projection of the common winding unit Q on the substrate 1 coincides with the orthographic projection of the heating winding unit P on the substrate 1.

[0060] In a possible embodiment, with reference to Figures 2A to 2D and Figure 3, the heating winding unit P includes: a first heating winding portion P1 and a second heating winding portion P2 extending along a first direction X and whose extension lines do not overlap, and a third heating winding portion P3 and a fourth heating winding portion P4 extending along a second direction Y and whose extension lines do not overlap; one end of the first heating winding portion P1 is electrically connected to an adjacent heating unit P, and the other end is electrically connected to one end of the third heating winding portion P3, the other end of the third heating winding portion P3 is electrically connected to one end of the second heating winding portion P2, the other end of the second heating winding portion P2 is electrically connected to one end of the fourth heating winding portion P4, and the other end of the fourth heating winding portion P4 is electrically connected to another adjacent heating unit P;

[0061] The common winding unit Q includes: a first common winding portion Q1 and a second common winding portion Q2 extending along a first direction X and whose extension lines do not overlap, and a third common winding portion Q3 and a fourth common winding portion Q4 extending along a second direction Y and whose extension lines do not overlap; one end of the first common winding portion Q1 is electrically connected to an adjacent common unit Q, and the other end is electrically connected to one end of the third common winding portion Q4, the other end of the third common winding portion Q3 is electrically connected to one end of the second common winding portion Q2, the other end of the second common winding portion Q2 is electrically connected to one end of the fourth common winding portion Q4, and the other end of the fourth common winding portion Q4 is electrically connected to another adjacent common unit Q.

[0062] In a possible embodiment, in combination with Figures 2A to 2D and Figure 3, at least part of the first sub-heating trace portion 321 has different lengths in the first direction X; at least part of the first common electrode portion 41 has different lengths in the first direction X. Specifically, for example, in combination with Figure 3, the length of the first sub-heating trace portion 321 from the left side in the first direction X is a1, and the length of the first sub-heating trace portion 321 on the rightmost side in the first direction X is a2, a1>a2; the length of the second first common electrode portion 41 from the left side in the first direction X is b1, and the length of the first common electrode portion 41 on the rightmost side in the first direction X is b2, b1>b2; in the embodiment of the present disclosure, at least part of the first sub-heating trace portion 321 has different lengths in the first direction X. Specifically, the closer the second heating trace portion 32 is to the electrically connected second terminal D20, the longer the first sub-heating trace portion 321 in the first direction X can be. For example, in Figure 3, the distance between the second second heating trace portion 32 from the left and the electrically connected second terminal D20 is greater than the distance between the second heating trace portion 32 on the rightmost side and the electrically connected second terminal S20. Then, the length of the first sub-heating trace portion 321 in the second second heating trace portion 32 from the left in the first direction X can be made greater than the length of the first sub-heating trace portion 321 in the second heating trace portion 32 on the rightmost side in the first direction X, so as to compensate for the different line resistances of the second heating trace portions 32 at different positions, so that the total line lengths of the second heating trace portions 32 at different positions are the same, thereby avoiding the problem of uneven heating effect caused by different line resistances of the second heating trace portions 32 of different lengths.

[0063] In one possible embodiment, as shown in conjunction with FIG1 , FIG2A-FIG2D , and FIG3 , the second heating trace portion 32 further includes: a plurality of second sub-heating trace portions 322 ; one end of the second sub-heating trace portion 322 is electrically connected to one end of the first sub-heating trace 321 , the other end of the second sub-heating trace portion 322 is electrically connected to the first heating trace portion 31 , and the other end of the first sub-heating trace 321 is electrically connected to the second terminal D2 ; specifically, the second sub-heating trace portion 322 may be linear;

[0064] The first common electrode portion 41 further includes: a plurality of second sub-common electrode portions 412; one end of the second sub-common electrode 412 is electrically connected to one end of the first sub-common electrode 411; specifically, the second sub-common electrode portion 412 may be linear;

In this way, each of the first common electrodes 41 forms an integrally connected structure, transmitting the same common signal.

[0067] In one possible embodiment, as shown in conjunction with Figures 1 and 4 , the common electrode 4 further includes: a third common electrode portion 43 located in the non-display area BB, the third common electrode portion 43 being located on the same side of the display area AA as the first terminal group D1; specifically, for example, the third common electrode portion 43 being located below the display area AA; and the third common electrode portion 43 including: a plurality of vias K, the plurality of vias K being distributed in an array. In the disclosed embodiment, the third common electrode portion 43 located on the same side as the first terminal group D1 can be arranged to form a grid structure composed of horizontally and vertically interlaced routing lines, avoiding the fan-shaped routing area where the data connection lines are located. This increases the light transmittance of this area and reduces the impact on the curing effect of the frame sealant when it is cured by ultraviolet light.

[0068] In one possible implementation, as shown in conjunction with Figures 2A-2D, 3, 5, and 6, the first heating trace 3 is located on a side of the common electrode 4 facing away from the substrate 1; the array substrate further includes an organic film layer 5 located between the first heating trace 3 and the common electrode 4. In the disclosed embodiment, the array substrate further includes an organic film layer 5 located between the first heating trace 3 and the common electrode 4, which can increase the distance between the first heating trace 3 and the common electrode 4, further reducing the coupling capacitance between the two, and thereby reducing the impact of signal coupling when the display panel is operating.

[0069] In a possible implementation, referring to FIG. 5 or FIG. 6 , the array substrate further includes: a gate insulating layer 81 located between the substrate 1 and the common electrode 4 , and a passivation layer 82 located on a side of the first heating trace 3 facing away from the substrate 1 .

In the disclosed embodiment, the array substrate further includes: a plurality of second heating traces 6 located in the non-display area BB and surrounding at least a portion of the display area AA, thereby enabling heating of the peripheral non-display area BB.

[0073] Specifically, for example, as shown in Figure 1, the side where the first terminal group D1 is located is used as the first non-display area, and the side where the second terminal group D2 is located is used as the second non-display area.
