Description

Array substrate and liquid crystal display panel Technical Field

[0001] The present invention relates to the field of display technology, and in particular to an array substrate and a liquid crystal display panel. Background Art

[0002] Liquid crystal display panels have been widely used due to their excellent characteristics such as high brightness, high contrast, and low cost. In order to meet special environmental requirements, liquid crystal display panels need to be able to operate normally in low-temperature environments. Under normal circumstances, since the viscosity coefficient of liquid crystal is significantly affected by temperature, in low-temperature environments, the viscosity coefficient of liquid crystal is relatively large, and the response time is too long, resulting in a tailing phenomenon on the display screen. To solve this problem, heating wires are usually evenly arranged inside the display area of ​​the liquid crystal display panel, and the display area is heated by the heat power generated by the heating wires. However, due to the different heat transfer and dissipation at different positions of the liquid crystal display panel, the temperature distribution of the entire display area is uneven. Generally, the temperature near the center of the display area is higher, while the temperature in the peripheral areas of the display area is lower. The uneven temperature distribution will cause differences in the response time of the liquid crystal in different areas, thereby affecting the display effect.

[0003] In order to solve the above problems, the existing technology is to compensate for the difference in heat dissipation in different areas of the display area by loading different heating signals (i.e., different voltages) to different heating wires so that the heat power generated is different. However, this compensation method can only control different heating wires separately, and the heat power of different positions of a single heating wire is consistent. This results in the inability to perform zoning control on different areas of the display area in the extension direction of the heating wire, and thus it is impossible to perform heat compensation in this extension direction, which has certain limitations for temperature uniformity control. In addition, for low temperature environments, although the temperature of the peripheral areas of the display area can be avoided from being too low by increasing the heating power of all heating wires, this can easily cause the temperature of the central area of ​​the display area to be too high, and increasing the temperature of all heating wires will also lead to an increase in overall power consumption.

[0004] Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art, and proposes an array substrate and a liquid crystal display panel, which can solve the problem in the prior art that heat compensation cannot be performed in the extension direction of the heating wire, resulting in uneven temperature distribution in the display area. Moreover, in a low temperature environment, there is no need to increase the heating power of all heating wires, thereby avoiding the problem of excessively high temperature in the central area and increased overall power consumption.

[0062] The embodiments of the present disclosure are not limited to the embodiments shown in the drawings, but include modifications of the configurations formed based on the manufacturing process. Therefore, the regions illustrated in the drawings are schematic in nature, and the shapes of the regions shown in the drawings illustrate the specific shapes of the regions of the elements, but are not intended to be limiting.

[0063] Referring to FIG. 1 , an embodiment of the present invention provides an array substrate comprising a display area AA and a peripheral area C surrounding the display area AA. The display area AA is divided into a plurality of heating sub-areas 1. The heating sub-areas 1 can be divided in various ways, such as by arranging the plurality of heating sub-areas 1 in an array. Optionally, to improve heating uniformity across the display area AA, the overall outline of the plurality of heating sub-areas 1 is substantially consistent with the outline of the display area AA (i.e., the dashed box in FIG. 1 ), and the spacing between adjacent heating sub-areas 1 is minimized, for example, to the distance between two adjacent sub-pixels.

[0064] A heating electrode is provided in each heating zone 1. Optionally, the orthographic projection outline of the heating electrode on the plane where the display area AA is located coincides with the outline of the heating zone 1, that is, the heating electrode completely covers the heating zone 1. This ensures that multiple heating electrodes substantially cover the entire display area AA, thereby facilitating improved heating uniformity. The heating zone 1 shown in FIG1 can also be represented as a heating electrode when the heating electrode completely covers the heating zone 1. Of course, in actual applications, it is also possible, according to specific needs, to provide a certain gap between the orthographic projection outline of the heating electrode on the plane where the display area AA is located and the outline of the heating zone 1, that is, the heating electrode partially covers the heating zone 1, as long as the requirements for heating uniformity are met.

[0065] The array substrate also includes a zoned temperature control module 3 and a heating wire module. The heating wire module includes multiple heating wire groups. Optionally, the heating wire group includes two heating wires 2, for example, a first heating wire and a second heating wire. Each heating wire group is provided corresponding to each heating zone 1, and the first end of each heating wire group (i.e., the right end of the heating wire 2 in Figure 1) is electrically connected to the zoned temperature control module 3.

[0066] The heating electrode plays the primary heating role, while each heating wire group plays an auxiliary heating role. At the same time, each heating wire group also plays the role of transmitting the heating signal. That is, taking the heating wire group including the first heating wire and the second heating wire as an example, any one of the first heating wire and the second heating wire is electrically connected to the signal input end of the zoned temperature control module 3, and the other is electrically connected to the signal output end of the zoned temperature control module 3. One heating wire 2 electrically connected to the signal input end of the zoned temperature control module 3 is used to input the heating signal output by the zoned temperature control module 3 into the heating electrode in the corresponding heating zone 1, and the other heating wire 2 electrically connected to the signal output end of the zoned temperature control module 3 is used to output the heating signal in the heating electrode to the zoned temperature control module 3, thereby forming a heating signal loop.

[0067] Optionally, taking the example of a heating wire group including a first heating wire and a second heating wire, the first heating wire and the second heating wire are electrically connected to the edge positions on both sides of the heating electrode in the corresponding heating zone 1. This allows the heating signal to pass through substantially the entire heating electrode, that is, flow from the edge position on one side of the heating electrode to the edge position on the other side, thereby avoiding the situation where the local area corresponding to the display area AA is not heated due to the lack of current passing through the local heating electrode, thereby improving the heating uniformity. In addition, by utilizing each heating wire group to transmit the heating signal, under the condition that the same heating signal intensity is applied to all heating electrodes, the uniformity of the heating effect of all heating electrodes can be guaranteed, thereby ensuring the accuracy of temperature compensation when it is necessary to compensate for temperature differences in different heating zones 1.

[0068] The partition temperature control module 3 can control each heating wire group to input a heating signal to the corresponding heating partition. Specifically, the partition temperature control module 3 is used to independently control the intensity and / or input time interval of the heating signal input to the heating electrode in the corresponding heating partition 1 through each heating wire group, that is, to achieve independent control of each heating electrode, so as to be able to control the intensity and / or input time interval of the heating signal of the heating electrode in the corresponding heating partition 1 according to the temperature difference between the heating partitions 1, so as to compensate for the temperature difference between the heating partitions 1, thereby making the temperature of the entire display area AA uniform, and further improving the display uniformity. The partition temperature control module 3, for example, includes a flexible circuit board (FPC) 31 and a chip-on-film 32 for controlling heating. The flexible circuit board 31 is electrically connected to the first end of each heating wire group, for example, through the chip-on-film 32.

[0069] By making the heating electrodes play the primary heating role and each heating wire group play an auxiliary heating role, the heating method of the present application, compared with the prior art, on the one hand, multiple heating electrodes can substantially cover the entire display area AA, thereby facilitating improved heating uniformity; on the other hand, the layout of the heating electrodes can be adapted to the division of the heating subareas 1, that is, more flexible subarea control can be performed without being restricted by the routing of the heating wires, thereby avoiding the problem in the prior art that different areas of the display area AA along the extension direction of the heating wires cannot be controlled by subareas and heat compensation cannot be performed in that extension direction, thereby achieving uniform temperature control of the entire display area AA. Furthermore, for low temperature environments, the embodiments of the present invention only need to increase the intensity and / or input time interval of the heating signal of the heating electrodes in the heating subareas 1 located around the display area AA to separately increase the temperature of the peripheral areas of the display area AA, that is, selective heating without the need to increase the power of all heating wires as in the prior art. This can prevent the temperature of the peripheral areas of the display area AA from being too low, while preventing the temperature of the central area of ​​the display area AA from being too high, and also avoid an increase in overall power consumption.

[0070] In some optional embodiments, taking the outline shape of the display area AA as a rectangle or a square as an example, a plurality of heating partitions 1 are arranged in an array within the display area AA, that is, arranged in an array in a first direction (i.e., the Y direction in Figure 1) and a second direction (i.e., the X direction in Figure 1) that are perpendicular to each other. A plurality of heating wire groups are arranged in parallel and spaced apart along the above-mentioned first direction, and the average lengths between adjacent heating wire groups are different. Taking the heating wire group including the first heating wire and the second heating wire as an example, the average length of the heating wire group refers to the average value of the lengths of the first heating wire and the second heating wire. In this way, when the first end of each heating wire group is electrically connected to the partition temperature control module 3, by making the average lengths between adjacent heating wire groups different, the positions of the second ends of adjacent heating wire groups can be made to correspond to different heating partitions 1, thereby enabling adjacent heating wire groups to be set corresponding to different heating partitions 1, so that the partition temperature control module 3 can independently control the heating electrodes in the corresponding heating partitions 1 through each heating wire group.

[0071] In some optional embodiments, the display area AA includes M×N array-arranged heating partitions 1, and each heating partition 1 includes m×n array-arranged sub-pixels, where M, N, m, and n are all positive integers. The first end of each heating wire group extends from the first side 1a of the display area AA and is electrically connected to the partition temperature control module 3. The first side 1a is the side of the display area AA closest to the partition temperature control module 3, that is, the side adjacent to the partition temperature control module 3. The second end of each heating wire group (the left end of the heating wire group in Figure 1) extends from the first side 1a along the first direction (i.e., the Y direction) to the corresponding heating partition 1, and the heating wire groups corresponding to each row of heating partitions 1 arranged along the first direction (i.e., the Y direction) are staggered with each other in the second direction (i.e., the X direction). Specifically, the first ends of all heating wire groups extend from the same side (i.e., the first side 1a), and the second ends extend in the same direction (i.e., perpendicular to and away from the first side 1a). All heating wire groups are parallel to each other. Preferably, the heating wires in the same heating wire group (e.g., including the first heating wire and the second heating wire) are of the same length, while the heating wires in different heating wire groups (e.g., including the first heating wire and the second heating wire) may have different lengths so that they can extend to their respective corresponding heating zones 1. Moreover, as shown in Figures 1 and 2, in each row of heating zones 1 arranged along the first direction (i.e., the Y direction), the second ends of each heating wire group corresponding to all heating zones 1 that are not adjacent to the first side 1a need to pass through the corresponding heating zone 1 in the row when extending along the first direction to the left in Figure 1. This requires that the heating wire groups corresponding to the heating zones 1 in the row be staggered in the second direction to ensure that the heating wire groups do not overlap with other heating wire groups when passing through the corresponding heating zones 1. For example, as shown in Figure 2, for each row of heating zones 1 arranged along the first direction (i.e., the Y direction), heating zone 11a is adjacent to the first side 1a, and the remaining heating zones (Figure 2 only shows two of them, 11b and 11c) are not adjacent to the first side 1a. For heating zone 11b, the second end of the corresponding heating wire group needs to pass through heating zone 11a; for heating zone 11c, the second end of the corresponding heating wire group needs to pass through heating zone 11a and heating zone 11b in sequence. Therefore, the length of each heating wire group is related to the distance between the corresponding heating zone and the first side 1a. The farther the distance, the longer the length, and vice versa.

[0072] In some optional embodiments, in each row of heating zones 1 arranged along the first direction (i.e., the Y direction), the farther away from the first side 1a, the smaller the spacing between the two heating wires 2 in the heating wire group corresponding to the heating zone 1. That is, the farther away from the first side 1a, the closer the two heating wires 2 in each heating wire group are to each other. This arrangement is intended to ensure that the area between each heating wire 2 in each heating wire group and the edge position of the heating zone 1 in which it is located will not be passed by the heating wire 2 in the heating wire group corresponding to other heating zones 1, and the heating wire groups corresponding to other heating zones 1 will only pass through the area between the two heating wires 2 in the heating wire group corresponding to the heating zone 1, so that the area between each heating wire 2 and the edge position of the heating zone 1 in which it is located can be used as a reserved space, so that an electrode connection structure (described in detail later) for electrically connecting the heating wire group to the heating electrode can be arranged in the space to avoid interference between the electrode connection structure and the heating wire groups corresponding to other heating zones 1 passing through. For example, as shown in FIG2 , for each row of heating zones 1 arranged along the first direction (i.e., the Y direction), the spacing (the distance in the X direction) between the two heating wires 2 in the heating wire group corresponding to heating zone 11a adjacent to the first side 1a is the largest, the spacing between the two heating wires 2 in the heating wire group corresponding to heating zone 11c is the smallest, and the spacing between the two heating wires 2 in the heating wire group corresponding to heating zone 11b is an intermediate value between the first two. The above-mentioned electrode connection structure is not shown in FIG1 .

[0073] In some optional embodiments, as shown in FIG2 , the heating lines 2 in each heating line group are located in a first pixel interval 1b, which is the interval between sub-pixels (e.g., sub-pixels R, G, and B) arranged along a first direction (i.e., Y direction) in any two adjacent rows or columns of display areas AA; and, for each row of heating partitions 1 arranged along a second direction (i.e., X direction), the first pixel interval 1b where a heating line group corresponding to one of the two adjacent heating partitions 1 is located is adjacent to the first pixel interval 1b where a heating line group corresponding to the other of the two adjacent heating partitions 1 is located. Specifically, for two adjacent heating zones 1 in the same row, the first heating line in the heating line group corresponding to one heating zone 1 and the first heating line in the heating line group corresponding to the other heating zone 1 are respectively located in two adjacent first pixel intervals 1b, and the second heating line in the heating line group corresponding to one heating zone 1 and the second heating line in the heating line group corresponding to the other heating zone 1 are respectively located in two adjacent first pixel intervals 1b. For example, if the first heating line in the heating line group corresponding to one heating zone 1 is located in the first pixel interval 1b closest to the edge of the heating zone in the second direction, then the first heating line in the heating line group corresponding to the other heating zone 1 is located in the first pixel interval 1b second closest to the edge of the heating zone in the second direction. As shown in FIG. 2 , the two heating lines 2 in the heating line group corresponding to heating zone 11a are both located in the first pixel interval 1b closest to the edge of the heating zone in the second direction, while the two heating lines 2 in the heating line group corresponding to heating zone 11b adjacent to heating zone 11a are both located in the first pixel interval 1b second closest to the edge of the heating zone in the second direction. In other words, the first heating lines in the heating line group corresponding to adjacent heating zones 1 in the same row are spaced apart by a sub-pixel; the second heating lines in the heating line group corresponding to adjacent heating zones 1 in the same row are spaced apart by a sub-pixel.

[0074] In this way, the number of heating line groups distributed in the same row of heating zones 1 can be maximized while ensuring normal display. It is easy to understand that the more heating line groups there are, the more heating zones 1 in the same row will also increase accordingly. The more zones there are, the higher the flexibility and accuracy of the zone temperature control, which is conducive to further improving the temperature uniformity of the display area AA. Optionally, as shown in Figure 2, heating lines 2 are provided in all first pixel intervals 1b in the heating zone 11a closest to the first side 1a, wherein two heating lines 2 in the heating line group corresponding to the heating zone 11a are respectively located in two first pixel intervals 1b adjacent to the edge of the heating zone 1, and the remaining first pixel intervals are used for the heating line groups corresponding to other heating zones other than the heating zone 11a to pass through. In this way, under the premise that only one heating line can be provided in each first pixel interval, the number of heating line groups in the same row of heating zones 1 reaches the maximum value, that is, the number of corresponding heating zones 1 in the same row is also the maximum. It can be seen that the maximum number of heating zones 1 in the same row depends on the resolution of the display panel.

[0075] Of course, in actual applications, the number of heating line groups provided in the same row of heating zones 1 can also be set according to actual needs. For example, it can be less than the above maximum value. In this case, there is at least one pair of adjacent heating zones 1 in the same row, and the first heating line in the heating line group corresponding to one heating zone 1 and the first heating line in the heating line group corresponding to the other heating zone 1 are respectively located in two non-adjacent first pixel intervals, and the second heating line in the heating line group corresponding to one heating zone 1 and the second heating line in the heating line group corresponding to the other heating zone 1 are respectively located in two non-adjacent first pixel intervals. The number of heating zones 1 in the same row can be freely set according to actual needs, and the embodiments of the present invention have no special restrictions on this.

[0076] In some optional embodiments, as shown in Figures 2, 3A to 3C, and 6, in each row of heating zones 1 arranged along the first direction (i.e., the Y direction), a heating line group corresponding to a heating zone 11a adjacent to the first side 1a includes two heating lines 2, namely a third heating line and a fourth heating line. The two heating lines 2 are respectively located in two first pixel intervals 1b adjacent to the edge of the heating zone 11a and are electrically connected to the edge positions on both sides of the heating electrode corresponding to the heating zone 11a through vias 21. Specifically, the heating electrode and the heating line group are arranged in different layers. The first pixel interval 1b where the two heating lines 2 in the heating line group corresponding to the heating partition 11a adjacent to the first side 1a are located is closest to the two side edges of the heating partition 11a in the second direction (i.e., the X direction) relative to the other first pixel intervals. In this case, the heating line group corresponding to the heating partition 11a adjacent to the first side 1a can be directly electrically connected to the heating electrode through the via 21, and the connection position is the edge position on both sides of the heating electrode (the position corresponding to the first pixel interval 1b closest to the two side edges of the heating partition 11a). In this way, the heating signal can pass through the entire heating electrode, that is, along the X direction, from the edge position on one side of the heating electrode to the edge position on the other side, thereby avoiding the local area corresponding to the display area AA from not being heated due to the local failure of current to pass through the heating electrode, thereby improving the heating uniformity. Specifically, a connecting portion 22 corresponding to the via 21 is provided on one side of the heating line 2 for realizing the electrical connection between the via 21 and the heating line 2.

[0077] In some optional embodiments, as shown in Figures 2 and 4A to 6, in each row of heating zones 1 arranged along the first direction, each heating line group corresponding to each heating zone not adjacent to the first side 1a (for example, the heating zone 11b shown in Figures 4A and 4B, and the heating zone 11c shown in Figures 5A and 5B) includes two heating lines 2, namely the fifth heating line and the sixth heating line, which extend through the connecting line structure to the two first pixel intervals adjacent to the edge of the heating zone 1 (i.e., the second interval 1b2 shown in Figures 4A and 5A), and are electrically connected to the edge positions on both sides of the heating electrode corresponding to the heating zone 1 through the via 21. Specifically, for each heating wire group corresponding to each heating zone that is not adjacent to the first side 1a (for example, the heating zone 11b shown in Figures 4A and 4B, and the heating zone 11c shown in Figures 5A and 5B), the first pixel interval (that is, the first interval 1b1 shown in Figures 4A and 5A) where each heating wire 2 is located is not adjacent to the two side edges of the heating zone in the second direction. In this case, the heating wire group cannot be directly electrically connected to the heating electrode through the via 21, otherwise the connection position cannot be located at the edge position on both sides of the heating electrode. For this purpose, it is necessary to use the above-mentioned connecting wire structure to first lead the heating wire 2 to the first pixel interval (that is, the second interval 1b2 shown in Figures 4A and 5A) adjacent to the edge of the heating zone (for example, the heating zones 11b and 11c shown in Figures 4A and 5A, respectively), and then electrically connect it to the edge position on both sides of the heating electrode corresponding to the heating zone through the via 21. The term "directing heater line 2 to the first pixel spacing adjacent to the edge of the heating subarea" means that the current in heater line 2 can flow to the first pixel spacing adjacent to the edge of the heating subarea 1 via the aforementioned connecting line structure. This connecting line structure is electrically connected to the edge of the corresponding heating electrode through vias 21, and heater line 2 is electrically connected to the connecting line structure, thereby indirectly electrically connecting to the edge of the heating electrode. This also allows the heating signal to pass through the entire heating electrode.

[0078] The embodiment of the present invention has no particular restrictions on the connection line structure for realizing the above-mentioned functions. In some optional embodiments, as shown in Figures 4A to 5B, the connection line structure includes a main connection line 51 and an auxiliary connection line 52, wherein the main connection line 51 is parallel to the first direction; the auxiliary connection line 52 intersects with the heating line (i.e., one of the fifth heating line and the sixth heating line) and is preferably perpendicular to each other; the first pixel interval (not adjacent to the edge of the heating zone) where the two heating lines 2, i.e., the fifth heating line and the sixth heating line are located is a first interval 1b1, and the first pixel interval adjacent to the edge of the heating zone is a second interval 1b2. As shown in Figure 5A, the first pixel interval between the first interval 1b1 and the second interval 1b2 is a third interval 1b3; a main connection line 51 is provided in each of the third interval 1b3 and the second interval 1b2, that is, a main connection line 51 is provided in each of all the first pixel intervals located on the side of each heating line 2 close to the edge of the heating zone, and the main connection line 51 is only located in the heating zone where it is located and does not extend to other heating zones. The auxiliary connection line 52 is located in the second pixel interval 1c, which is the interval between any two adjacent columns of sub-pixels arranged along the second direction (i.e., the X direction). At least one auxiliary connection line 52 is connected between each two adjacent main connection lines 51, and at least one auxiliary connection line 52 is connected between each heating line 2 in the heating line group, that is, each of the fifth heating line and the sixth heating line, and the adjacent main connection line 51. With the help of the auxiliary connection line 52, electrical conduction can be established between the main connection lines 51, and between the heating line group and the main connection line 51. Therefore, each heating line 2 in the heating line group, that is, each of the fifth heating line and the sixth heating line, can be led to the second interval 1b2 mentioned above. The main connection line 51 in the second interval 1b2 is electrically connected to the edge positions on both sides of the heating electrode corresponding to the heating partition through the via 21.

[0079] Since the above-mentioned main connecting line 51 can also play a role in auxiliary heating, by providing a main connecting line 51 in each of all the first pixel intervals located on the side of the heating line group close to the edge of the heating zone, the heating effect of the heating zone in which it is located is basically equivalent to the heating effect of the heating zone closest to the first side 1a (that is, the heating zone 11a in Figure 2, all the first pixel intervals have a heating line group), and the influence of the auxiliary connecting line 52 can be ignored. Under the condition of loading the same heating signal intensity to all the heating electrodes, the uniformity of the heating effects between the heating zones can be further improved, so that when it is necessary to compensate for the temperature difference between different heating zones, the accuracy of temperature compensation can be guaranteed.

[0080] In some optional embodiments, a via 21 is provided in at least one second pixel interval in each heating partition (i.e., the second pixel interval 1c in FIG. 5A above), and the second pixel interval 1c is the interval between any two adjacent columns of sub-pixels arranged along the second direction. This can prevent the setting of the via 21 from affecting the light transmittance and light efficiency of the display area AA. Optionally, a via 21 can be provided on one side of each sub-pixel R, and a via 21 can be provided on one side of each sub-pixel B. For example, as shown in FIG. 3A , FIG. 4A and FIG. 5A , a via 21 can be provided on the left side of each sub-pixel R, and a via 21 can be provided on the right side of each sub-pixel B; or, as shown in FIG. 3B , FIG. 4B and FIG. 5B , a via 21 can also be provided on the left side of each sub-pixel R, and a via 21 can be provided on the left side of each sub-pixel B. There is no particular limitation on this in the embodiment of the present invention, as long as the setting of the via 21 does not affect the light transmittance and light efficiency of the display area AA.

[0081] In some optional embodiments, as shown in Figures 3C and 6, the array substrate includes a base substrate 13 and a thin film transistor 23 and a passivation layer 15 arranged on the base substrate 13 and sequentially arranged in a direction away from the base substrate 13, and each sub-pixel is correspondingly provided with a thin film transistor 23; each heating electrode 12 is arranged on the side of the passivation layer 15 away from the base substrate 13; and the array substrate also includes an insulating layer 14, each heating line group (heating line 2) is arranged on the base substrate 13, and the insulating layer 14 is arranged between the layer where each heating line group is located and the gate layer 231; the array substrate also includes a data line 24, and the via 21 is located on the side of the data line 24 away from the thin film transistor 23, and is arranged between the heating electrode 12 and the corresponding heating line group (heating line 2), and sequentially penetrates the passivation layer 15, the gate insulating layer 232 of the thin film transistor 23 and the insulating layer 14 along the direction close to the base substrate 13.

[0082] In some optional embodiments, as shown in FIG3C and FIG6 , the orthographic projections of the heating line 2 in each heating line group and a data line 24 adjacent to the first pixel interval in which the heating line 2 is located overlap on the base substrate 13; and the width of the heating line 2 in each heating line group is less than or equal to the width of the data line 24. This can prevent the heating line 2 from affecting the light transmittance of the display area AA. At the same time, by ensuring that the width of the heating line 2 in each heating line group is less than or equal to the width of the data line 24, the negative impact of the electric field generated by the heating line 2 and the data line 24 opposite thereto can be reduced, thereby ensuring the display effect.

[0083] In some optional embodiments, the heating electrode can be an additional electrode provided on the basis of the structure of the existing array substrate. Preferably, the heating electrode is a transparent metal oxide electrode block, and the transparent metal oxide includes, for example, ITO. The heating wire material in the heating wire group is a conductive metal, and the conductive metal includes, for example, any one or more of aluminum, copper and molybdenum. Due to the square resistance of the conductive metal (for example, aluminum is about 0.15Ω / μm 2 , molybdenum is about 0.38Ω / μm 2 ) is generally much smaller than the sheet resistance of transparent metal oxide electrode blocks (ITO is about 27Ω / μm 2 ), which makes the resistance of the transparent metal oxide electrode block much greater than that of the conductive metal. According to the power formula P=IR2, it can be seen that the greater the resistance R, the greater the thermal power. Therefore, the heat generated will be mainly concentrated in the transparent metal oxide electrode block, that is, the transparent metal oxide electrode block plays the main heating role, and the conductive metal plays an auxiliary heating role. In this way, under the condition that the same heating signal intensity is loaded to all transparent metal oxide electrode blocks, the uniformity of the heating effect of all transparent metal oxide electrode blocks can be guaranteed, so that when it is necessary to compensate for the temperature difference of different heating zones, the accuracy of temperature compensation can be guaranteed. Of course, in actual applications, according to actual needs, the material of the heating line can also be a transparent metal oxide such as ITO. In addition, the material of the above-mentioned main connecting line 51 and the auxiliary connecting line 52 can also be a conductive metal or a transparent metal oxide such as ITO.

[0084] In other optional embodiments, the electrodes in the existing array substrate can also be reused as heating electrodes. For example, the array substrate also includes a common electrode, and the common electrode includes a plurality of transparent metal oxide electrode blocks, and the transparent metal oxide electrode blocks can be reused as the above-mentioned heating electrodes. The common electrode has both display and heating functions. Since the common electrode adopts a transparent metal oxide electrode block, the heat generated can be mainly concentrated in the transparent metal oxide electrode block, so that under the condition that the same heating signal intensity is loaded to all transparent metal oxide electrode blocks, the uniformity of the heating effect of all transparent metal oxide electrode blocks can be guaranteed. Optionally, as shown in Figure 6, the heating electrode 12 also serves as a common electrode, and the heating electrode 12 and the heating wire group are arranged in different layers. In this case, the heating electrode 12 is electrically connected to each heating wire 2 through a via 21. However, the embodiment of the present invention is not limited to this. In actual applications, each heating wire group can also be arranged in the same layer as the common electrode (reused as a heating electrode) without the need for a via.

[0085] In order to ensure that the above two functions of the common electrode (i.e., display and heating) can be performed normally, the following three different methods can be used to input the heating signal and the display drive signal into the common electrode. The first method is that, as shown in Figure 1, the array substrate also includes a display driver module 4, and the display driver module 4, for example, includes a flexible circuit board (FPC) 41 and an integrated circuit 43 for controlling the display, and the flexible circuit board 41 is electrically connected to the integrated circuit 43 through a signal transmission pin (FPC Pin) 42. Optionally, the display driver module 4 and the partition temperature control module 3 are both located in the peripheral area C, and the partition temperature control module 3 is adjacent to the first side 1a of the display area AA, and the display driver module 4 is adjacent to the second side 1b of the display area AA, and the first side 1a intersects with the second side 1b; the first end of each heating wire group extends from the first side 1a and is electrically connected to the partition temperature control module 3. As shown in FIG8 , the display driving module 4 is used to periodically input a driving signal (Source) to a plurality of transparent metal oxide electrode blocks. Each cycle of the driving signal includes a signal-on period (i.e., the period corresponding to the display time of the Source signal in FIG8 ) and a signal-off period. The partitioned temperature control module 3 inputs a heating signal (Com) to each transparent metal oxide electrode block during the signal-off period, and stops inputting the heating signal to each transparent metal oxide electrode block during the signal-on period. Each cycle of the above-mentioned driving signal is, for example, the duration of a frame of display image, and the duration is divided into two periods, one of which is used for display, and at least a portion of the duration of the other period is used for heating. In this case, the partitioned temperature control module 3 can be used to control the temperature of the corresponding heating partition 1 by controlling the duration of the heating signal in the signal-off period of each cycle (i.e., the length of the period corresponding to the heating time of the Com signal in FIG8 ).

[0086] The second method is that the common electrode can also be reused as a touch electrode, which has three functions: display, touch, and heating. The array substrate also includes a touch driver module and a display driver module. In this case, as shown in Figure 7, there is no need to set up a separate zone temperature control module. Moreover, optionally, the display driver module and the touch driver module are integrated together and located in the peripheral area C. The integrated display driver module and the touch driver module are adjacent to the second side 1b of the display area AA; the first end of each heater wire group extends from the second side 1b and is electrically connected to the integrated display driver module and the touch driver module. Specifically, the integrated display driver module and the touch driver module include a flexible circuit board (FPC) 41' and an integrated circuit 43, the side of the display area AA where they are located is the above-mentioned second side 1b, for example, the second side 1b is parallel to the Y direction. The first end of each heater wire group is electrically connected to the touch driver module and the display driver module, that is, of the two heater wires in each heater wire group, the first end of one heater wire is electrically connected to the touch driver module, and the first end of the other heater wire is electrically connected to the display driver module. In this case, the flexible printed circuit (FPC) 41' and the integrated circuit 43 have a TDDI (Touch and Display Driver Integration) function, that is, the above-mentioned touch driver module and display driver module are integrated. Since the frequency and intensity of the touch signal output by the touch driver module are adjustable, and by electrically connecting the first end of one of the heating wires to the touch driver module and the first end of the other heating wire to the display driver module, the heating signal can form a loop, so that the touch driver module can be used as the above-mentioned partitioned temperature control module. Specifically, as shown in FIG9 , the display driver module is configured to periodically input a drive signal (Source) to a plurality of transparent metal oxide electrode blocks. Each cycle of the drive signal includes a signal-on period (i.e., the period of the Source signal in FIG9 corresponding to the display time) and a signal-off period. The touch driver module is multiplexed as a zoned temperature control module. During the signal-off period, a touch signal (Com) is input to each transparent metal oxide electrode block, and the touch signal is simultaneously used as a heating signal. The intensity and / or input time interval of the touch signal input to the transparent metal oxide electrode block in the corresponding heating zone are independently controlled. During the signal-on period, the touch signal input to each transparent metal oxide electrode block is stopped. Each cycle of the drive signal is, for example, the duration of a single display frame, which is divided into two periods: one period is used for display, and at least a portion of the other period is used for both touch control and heating.In this case, the touch driving module serving as a partition temperature control module can be used to control the temperature of the corresponding heating partition by controlling the duration of the touch signal (also the heating signal) in the signal-off period of each cycle (i.e., the length of the period corresponding to the heating time + touch time of the Com signal in FIG9 ).

[0087] In the case where there are high requirements for the uniformity of the surface temperature of the liquid crystal display panel, in order to meet the requirements of touch recognition, the intensity of the touch signal and the duration in each cycle of the driving signal (the length of one frame of display picture) are equal. In this case, since the temperature of the heating zone cannot be adjusted by changing the heating time, the touch signal cannot be used as a heating signal at the same time. In this case, a third method can be adopted, that is, the common electrode can also be reused as a touch electrode, that is, the common electrode has three functions of display, touch and heating. The array substrate also includes a touch driver module and a display driver module. Similar to the second method mentioned above, the integrated display driver module and touch driver module include a flexible circuit board (FPC) 41' and an integrated circuit 43, which has a TDDI (Touch and Display Driver Integration) function. The first end of each heating wire group is electrically connected to the touch driver module and the display driver module respectively. That is, among the two heating wires in each heating wire group, the first end of one heating wire is electrically connected to the touch driver module, and the first end of the other heating wire is electrically connected to the display driver module, so that the heating signal can form a loop, thereby enabling the touch driver module to be used as the above-mentioned partition temperature control module. Specifically, as shown in Figure 10, the display driving module is used to periodically input a driving signal (Source) to multiple transparent metal oxide electrode blocks, and each cycle of the driving signal includes a signal-on period (i.e., the period of the Source signal in Figure 10 corresponding to the display time) and a signal-off period; the touch driving module is used as a partitioned temperature control module, and in the first sub-period of the signal-off period (i.e., the period of the Com signal in Figure 10 corresponding to the touch time), a touch signal (Com) is input to each transparent metal oxide electrode block separately, and in the second sub-period of the signal-off period (i.e., the period of the Com signal in Figure 10 corresponding to the heating time), a heating signal (Com) is input to each transparent metal oxide electrode block separately, and in the signal-on period, the input of touch signals and heating signals to each transparent metal oxide electrode block is stopped. That is to say, although the touch driving module is still used as a partition temperature control module, the touch signal and the heating signal output by the touch driving module are not in the same time period and cannot be output at the same time. In this way, it can ensure that the duration of the touch signal output in the first sub-time period in each cycle of the driving signal (the length of one frame of display screen) is equal, and the duration occupied by the heating signal output in the second sub-time period in the signal-off period of each cycle (that is, the size of the second sub-time period) can be used to control the temperature of the corresponding heating zone.

[0088] In summary, the array substrate provided by the embodiments of the present invention has a heating electrode that performs the primary heating function, while each heating wire group performs the auxiliary heating function. Compared to the heating wires in the prior art, on the one hand, the multiple heating electrodes can substantially cover the entire display area AA, thereby facilitating improved heating uniformity. On the other hand, the layout of the heating electrodes can be adapted to the division of the heating subareas 1, i.e., more flexible subarea control can be performed without being restricted by the routing of the heating wires. This avoids the problem in the prior art of being unable to perform subarea control in different areas of the display area AA along the extension direction of the heating wires, and thus being unable to perform heat compensation in that extension direction. Thus, uniform temperature control of the entire display area AA can be achieved. Furthermore, in low-temperature environments, the embodiments of the present invention only need to increase the intensity and / or input time interval of the heating signal of the heating electrodes in the heating subareas 1 located around the display area AA to separately increase the temperature of the peripheral areas of the display area AA, i.e., selective heating without the need to increase the power of all the heating wires as in the prior art. This prevents the temperature of the peripheral areas of the display area AA from being too low, while also preventing the temperature of the central area of ​​the display area AA from being too high, and also avoids an increase in overall power consumption.

[0089] At the same time, each heating wire group also functions as a heating signal transmitter. Furthermore, by electrically connecting the two heating wires 2 in each heating wire group to the edges of the heating electrodes in the corresponding heating subareas 1, the heating signal can pass through the entire heating electrode, thereby preventing the local area corresponding to display area AA from being unheated due to a lack of current flowing through a portion of the heating electrode, thereby improving heating uniformity. Furthermore, by utilizing each heating wire group to transmit the heating signal, the heating effect of all heating electrodes can be guaranteed to be uniform, provided that the same heating signal intensity is applied to all heating electrodes. This ensures the accuracy of temperature compensation when temperature differences between different heating subareas 1 need to be compensated.

[0090] As another technical solution, an embodiment of the present invention further provides a liquid crystal display panel, comprising the above-mentioned array substrate provided by an embodiment of the present invention.

[0091] The liquid crystal display panel provided by the embodiment of the present invention, by adopting the above-mentioned array substrate provided by the embodiment of the present invention, can avoid the problem in the prior art that different areas of the display area AA in the extension direction of the heating wire cannot be zoned and controlled, and heat compensation cannot be performed in the extension direction, thereby achieving uniform control of the temperature of the entire display area AA.

[0092] It should be understood that the above embodiments are merely exemplary embodiments for illustrating the principles of the present invention, and the present invention is not limited thereto. Those skilled in the art may make various modifications and improvements without departing from the spirit and essence of the present invention, and such modifications and improvements are also considered to be within the scope of protection of the present invention.
