[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. The thickness and shape of each film layer in the drawings do not reflect the actual proportion, and the purpose is only to illustrate the contents of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0029] Unless otherwise defined, the technical or scientific terms used herein shall have the usual meanings understood by persons of ordinary skill in the field to which the present disclosure belongs. The words "first", "second" and similar terms used in the present disclosure specification and claims 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 appearing before 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 described object changes, the relative positional relationship may also change accordingly.

[0030] In the related art, when a touch operation occurs, the finger will form a coupling capacitor between the touch screen surface and the ground, thereby increasing the capacitance of the touch electrode to the ground and causing a change in the capacitance on the touch electrode layer. The touch detection chip (IC) identifies this change to determine the touch position and make a response action, thereby realizing the recognition of the touch signal. However, in the related art, a touch line generally overlaps with a column of touch electrodes and is electrically connected to one of the touch electrodes in the column to identify the capacitance change of the touch electrode. Obviously, there will be a coupling capacitor between the touch line and other touch electrodes in the column other than the touch electrode electrically connected to it, which will affect the touch accuracy.

[0031] In view of the above problems existing in the related art, the present disclosure provides an array substrate suitable for products of low temperature polycrystalline silicon (LTPS) process, specifically, Figure 1 and Figure 2 As shown, the array substrate includes:

[0032] Base substrate 101;

[0033] A plurality of touch lines 102 are located on the base substrate 101;

[0034] The touch electrode layer is located at a side of the layer where each data line 102 is located away from the base substrate 101 . The touch electrode layer includes a plurality of touch electrodes 103 . Each touch electrode 103 has a hollow area at the location of each touch line 102 .

[0035] In the above-mentioned array substrate provided in the embodiment of the present disclosure, since each touch line 102 is located in the hollow area of ​​the touch electrode 103, overlap between the touch electrode layer and each touch line 102 is avoided, thereby reducing the coupling capacitance between the touch line 102 and the touch electrode layer, reducing the signal-to-noise ratio, saving power consumption, and improving touch accuracy.

[0036] It should be noted that in the above array substrate provided in the embodiment of the present disclosure, the base substrate 101 can be a flexible base substrate, such as a plastic substrate with excellent heat resistance and durability such as polyethylene ether phthalate, polyethylene naphthalate, polycarbonate, polyarylate, polyetherimide, polyethersulfone or polyimide; it can also be a rigid base substrate, such as a glass substrate, which is not limited here. Specifically, the touch line 102 can be formed of molybdenum, aluminum, silver, copper, titanium, platinum, tungsten, tantalum, tantalum nitride, alloys thereof, combinations thereof or other suitable materials, which is not limited here.

[0037] In the related art, the touch function and the display function are performed in time-sharing within one frame time, resulting in insufficient pixel charging rate. Based on this, in order to improve the pixel charging rate, in the above-mentioned array substrate provided in the embodiment of the present disclosure, Figure 1 As shown, the touch electrode 103 includes: a plurality of first touch electrodes 1031 and a second touch electrode 1032 surrounding each of the first touch electrodes 1031 ; there is a gap between the second touch electrode 1032 and each of the first touch electrodes 1031 and they are insulated from each other.

[0038] It should be noted that if Figure 1 As shown, one second touch electrode 1032 extending in the row direction surrounds two rows of first touch electrodes 1031. In a specific implementation, one second touch electrode 1032 extending in the row direction may also surround one or at least three rows of first touch electrodes 1031, which may be specifically set according to the actual required touch density and is not limited here.

[0039] In addition, in some embodiments, the first touch electrode 1031 is a driving electrode (T x sensor), the second touch electrode 1032 is a sensing electrode (R xIn some other embodiments, the first touch electrode 1031 is a sensing electrode, and the second touch electrode 1032 is a driving electrode, which is not limited here.

[0040] Depend on Figure 1 It can be seen that a "U"-shaped ring structure is formed between the first touch electrode 1031 and the second touch electrode 1032, so that the touch position can be identified based on the self-capacitance principle and the mutual capacitance principle at the same time. Moreover, the self-mutual capacitance integrated technology can also realize the synchronization of touch function and display function, thereby improving the pixel charging rate. In addition, the self-mutual capacitance integrated technology also has the advantages of supporting active pens and waterproofing, and is suitable for the development of mobile products (such as mobile phones) that comply with the stylus pen protocol. In addition, it can be understood that when the product size is the same, the number of self-mutual capacitance integrated touch electrodes provided in the present disclosure will be less than the number of touch electrodes based on a single self-capacitance or a single mutual capacitance, thereby reducing the number of touch channels and realizing a narrow frame design.

[0041] Optionally, in the above array substrate provided in the embodiment of the present disclosure, if Figure 2 As shown, the touch electrode layer further includes: a plurality of overlapping portions 104 , each overlapping portion 104 is connected to the first touch electrode 1031 or the second touch electrode 1032 on both sides of the hollow area.

[0042] Since the interior of the same first touch electrode 1031 is disconnected due to the hollow area, the overlapping portion 104 ensures signal consistency on the same first touch electrode 1031. Similarly, the interior of the same second touch electrode 1032 is disconnected due to the hollow area, and the overlapping portion 104 also ensures signal consistency on the same second touch electrode 1032.

[0043] In addition, it is understandable that the first touch electrode 1031 and the second touch electrode 1032 need to be insulated from each other, so there is no need to provide the overlapping portion 104 to connect the first touch electrode 1031 and the second touch electrode 1032 on both sides of the hollow area. In other words, a gap formed by the hollow area is left between the first touch electrode 1031 and the second touch electrode 1032 to ensure that there is no short circuit between the first touch electrode 1031 and the second touch electrode 1032, so that the signals of the two do not interfere with each other.

[0044] Optionally, in the above array substrate provided in the embodiment of the present disclosure, if Figure 2 As shown, a plurality of gate lines 105 intersecting the touch lines 102 may be further included, and each overlapping portion 104 is disposed at the intersection of each touch line 102 and gate line 105 in a one-to-one correspondence.

[0045] Since the overlapping portions 104 also have coupling capacitance with the touch lines 102 in the hollow area to a certain extent, it is necessary to reasonably set the number and positions of the overlapping portions 104. The overlapping portions 104 are arranged one by one at the intersections of the touch lines 102 and the gate lines 105, which not only ensures the uniformity of the signal on the first touch electrode 1031 or the second touch electrode 1032, but also avoids excessive overlapping portions 104 and large coupling interference with the touch lines 102.

[0046] Optionally, in the above array substrate provided in the embodiment of the present disclosure, if Figure 2 and Figure 3 As shown, it also includes: a plurality of data lines 106 arranged to cross each gate line 105 and arranged in the same layer as each touch line 102;

[0047] A data line 106 is disposed in a hollow area corresponding to each touch line 102 .

[0048] It should be noted that, in the present disclosure, "same-layer arrangement" refers to the use of the same film-forming process to form a film layer for forming a specific pattern, and then using the same mask to form a layer structure through a single patterning process. That is, one patterning process corresponds to one mask. Depending on the specific pattern, a single patterning process may include multiple exposure, development or etching processes, and the specific pattern in the formed layer structure may be continuous or discontinuous, and these specific patterns may also be at different heights or have different thicknesses. Therefore, the touch line 102 and the data line 106 are arranged in the same layer, which can reduce the mask process and improve production efficiency.

[0049] Generally, because the touch density is less than the display density (Pixels Per Inch, PPI), one touch electrode covers multiple sub-pixels, for example, one touch electrode covers M*N sub-pixels, where M and N are integers greater than 1. On this basis, it should be understood that the number of data lines 106 is greater than the number of touch lines 102.

[0050] Specifically, each data line 106 and each gate line 105 define a plurality of sub-pixel regions, such as Figure 2 and Figure 3As shown, it includes: a red sub-pixel area R, a green sub-pixel area G and a blue sub-pixel area B. The sub-pixel areas in the same column have the same color, and are arranged cyclically in the row direction with "red sub-pixel area R, green sub-pixel area G and blue sub-pixel area B" as a period. The column where the red sub-pixel area R, the column where the green sub-pixel area G and the column where the blue sub-pixel area B are contained in each cycle constitute a pixel column, and each column of sub-pixel areas corresponds to a data line 106. Of course, in a specific implementation, in order to improve the display brightness, the sub-pixel area defined by the data line 106 and the gate line 105 can also be a white sub-pixel area W. In addition, a black matrix may be set in the areas corresponding to the row gaps and column gaps of the red sub-pixel area R, the green sub-pixel area G, and the blue sub-pixel area B. On the one hand, light crosstalk between adjacent sub-pixel areas may be prevented; on the other hand, the black matrix may be used to shield the gate line 105 at the row gaps, and the data line 106 and the touch line 102 at the column gaps, thereby preventing the touch line 102, the gate line 105, and the data line 106 from being visible to the naked eye, thereby improving the product appearance experience.

[0051] Specifically, in the above array substrate provided by the embodiment of the present disclosure, the touch control line 102 includes a touch control driving line (T x line) and touch sensing line (R x Since the touch driving line and the touch sensing line extend in the same direction as the data line 102, the touch detection chip can be arranged on the same side of the array substrate to achieve single-sided driving and obtain a narrow frame effect.

[0052] Optionally, in the above array substrate provided in the embodiment of the present disclosure, if Figure 2 and Figure 4 As shown, the hollow area covers the column gap between the column where the blue sub-pixel area B is located and the column where the red sub-pixel area R is located, which are defined by the gate line 105 and the data line 106 .

[0053] Specifically, the hollow area can completely cover and be larger than the column gap between the column where the blue sub-pixel area B is located and the column where the red sub-pixel area R is located defined by the gate line 105 and the data line 106. In other words, the orthographic projection of the column gap between the column where the blue sub-pixel area B is located and the column where the red sub-pixel area R is located on the substrate 101 is located within the orthographic projection of the hollow area; or, the hollow area can also completely overlap with the column gap between the column where the blue sub-pixel area B is located and the column where the red sub-pixel area R is located defined by the gate line 105 and the data line 106. In other words, the shape and size of the orthographic projection of the column gap between the column where the blue sub-pixel area B is located and the column where the red sub-pixel area R is located on the substrate 101 are exactly the same as the shape and size of the orthographic projection of the hollow area. Considering that in the case where the touch electrode 103 is reused with the common electrode, the electric field strength between the common electrodes on both sides of the hollow area and the pixel electrodes facing it is limited by the facing area of ​​the two. Therefore, to ensure the electric field strength between the common electrode and the pixel electrode, preferably, the hollow area completely overlaps with the column gap between the blue sub-pixel region B and the red sub-pixel region R defined by the gate line 105 and the data line 106 .

[0054] Optionally, in the above array substrate provided in the embodiment of the present disclosure, if Figure 3 As shown, in the same hollow area, the touch line 102 is located between the data line 106 and the column where the blue sub-pixel area B is located.

[0055] Since the sensitivity of human eyes to blue is weaker than that to red and green, the touch line 102 is disposed adjacent to the column where the blue sub-pixel region B is located, which will not affect the viewing experience.

[0056] Optionally, in the above array substrate provided in the embodiment of the present disclosure, if Figure 2 and Figure 3 As shown, the touch line 102 has a wavy structure, which is composed of a plurality of arc segments and a straight line segment connecting two adjacent arc segments. Of course, in a specific implementation, the wavy structure can also be composed of only a plurality of arc segments.

[0057] In the related art, the straight touch line 102 extending in a direction perpendicular to the gate line 105 is prone to cause light interference with regular shapes in the touch screen, such as the pattern of the black matrix, resulting in a moiré phenomenon, which affects the display effect. Based on this, by setting the touch line 102 to a wavy structure, the moiré caused by the interference of light caused by the regular pattern of the touch line 102 can be reduced, the visibility of the moiré on the touch screen surface is eliminated, and the display quality is improved.

[0058] Optionally, in the above array substrate provided in the embodiment of the present disclosure, if Figure 2 and Figure 3As shown, the two arc segments located on both sides of the same gate line 105 are mirror-symmetrical with respect to the gate line 105 , and the straight line segment connecting the two arc segments is mirror-symmetrical with respect to the gate line 105 .

[0059] The straight line segment connecting the two arc segments in the touch line 102 is set to be mirror-symmetrical with respect to the gate line 105, so that the hollow area covering the touch line 102 is a local hollow area at the intersection of the gate line 105 with a rectangular shape. In addition, it can be understood that when the extension direction of the border of the touch electrode 103 on both sides of the hollow area is parallel to the extension direction of the touch line 102, it is equivalent to the local hollow area at the intersection of the hollow area and the gate line 105 being a rectangle. In addition, it can be seen from the above description that the overlap portion 104 is located at the intersection of the gate line 105 and the touch line 102 to connect the first touch electrode 1031 or the second touch electrode 1032 on both sides of the hollow area. Therefore, the overlap portion 104 needs to cover the above-mentioned local hollow area. When the above-mentioned local hollow area is in a rectangular shape, it is convenient to realize the production of the overlap portion 104 and improve production efficiency.

[0060] Optionally, in the array substrate provided in the embodiment of the present disclosure, the data line 106 is parallel to the touch line 102. By setting the data line 106 to have the same wavy structure as the touch line 102, the moiré pattern caused by the interference of light due to the regular pattern of the data line 106 can be reduced, the visibility of the moiré pattern on the touch screen surface is eliminated, and the display quality is improved.

[0061] Optionally, in the above array substrate provided in the embodiment of the present disclosure, if Figure 3 and Figure 4 As shown, it also includes: a plurality of pixel electrodes 107 located on the touch electrode layer (ie, the layer where the touch electrode 103 is located) away from the layer where the data lines 106 are located;

[0062] The extending direction of the pixel electrode 107 is parallel to the extending direction of the data line 106 defining the sub-pixel region where the pixel electrode 107 is located.

[0063] Since the data lines 106 on both sides of the same gate line 105 are mirror-symmetrical with respect to the gate line 105, when the extension direction of the pixel electrode 108 is parallel to the extension direction of the data line 106 defining the sub-pixel region where the pixel electrode 108 is located, the two pixel electrodes 108 on both sides of the same gate line 102 have two domains (i.e., 2Pixel 2Domain) that are mirror-symmetrical with respect to the gate line 105. The pixel electrode 108 is designed to have a certain pre-tilt angle, so as to achieve better effects in terms of transmittance and light efficiency.

[0064] It is worth noting that, in order to facilitate the distinction, Figure 2 and Figure 3In the figure, the position of the touch line 102 is shown by a solid line, and the position of the data line 106 is shown by a dotted line. Figure 2 In FIG. 1 , the white area represents the hollow area of ​​the touch electrode 103, and the pattern-filled area represents the touch electrode 103. Figure 3 In the figure, the white area represents the row gaps between the rows where the pixel electrodes 107 are located, and the column gaps between the columns where the pixel electrodes 107 are located, and the pattern-filled area represents the pixel electrodes 107 .

[0065] Optionally, the array substrate provided in the embodiment of the present disclosure further includes: a common electrode layer, and the common electrode layer is reused as a touch electrode layer.

[0066] By reusing the touch electrode layer as a common electrode layer, the thickness of the touch screen can be reduced to achieve a lightweight design. Optionally, the first touch electrode 1031, the second touch electrode 1032 and the overlapping portion 104 included in the touch electrode layer can be in the same layer and the same material. And when the first touch electrode 1031, the second touch electrode 1032 and the overlapping portion 104 are in the same layer and the same material, the first touch electrode 1031, the second touch electrode 1032 and the overlapping portion 104 can be manufactured at the same time to simplify the manufacturing process of the array substrate. Optionally, the material of the first touch electrode 1031, the second touch electrode 1032 and the overlapping portion 104 is a transparent conductive material. Exemplarily, the material of the first touch electrode 1031, the second touch electrode 1032 and the overlapping portion 104 is a material with good light transmittance and conductivity such as indium tin oxide or indium zinc oxide.

[0067] Optionally, in the above array substrate provided in the embodiment of the present disclosure, if Figure 4 As shown, it can generally also include a layer 108 where the transistor is located. When the touch electrode layer (i.e., the layer where the touch electrode 103 is located) is reused as a common electrode layer, an insulating layer 109 is arranged between the pixel electrode 107 and the common electrode layer. Among them, the layer 108 where the transistor is located includes: a gate, a gate insulation layer, an active layer, an interlayer dielectric layer and a source and drain layer. Specifically, a flat layer (not shown in the figure) is generally arranged between the layer 108 where the transistor is located and the common electrode layer. In addition, when the common electrode layer is arranged between the layer 108 where the transistor is located and the pixel electrode 107, the pixel electrode 107 can be electrically connected to the transistor through the via H on the common electrode layer, as shown in FIG. Figure 2 Further, to simplify the process, the two via holes H on both sides of the gate line 105 can be set as an integrated design, such as Figure 2 Specifically, the via H may have a variety of shapes, such as a circle, a triangle, a rectangle, a rhombus, a trapezoid, a pentagonal star, a regular polygon, or any other regular or irregular shapes, which are not limited here.

[0068] Based on the same inventive concept, the embodiment of the present disclosure also provides a display device, including the above-mentioned array substrate provided in the embodiment of the present disclosure. The display device can be: a liquid crystal display panel, a mobile phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame, a navigator, a smart watch, a fitness wristband, a personal digital assistant, and any other product or component with a display function. The other essential components of the display device should be understood by ordinary technicians in the field, and will not be repeated here, nor should they be used as a limitation to the present disclosure. In addition, since the principle of solving the problem by the display device is similar to the principle of solving the problem by the above-mentioned display panel, the implementation of the display device can refer to the embodiment of the above-mentioned display panel, and the repeated parts will not be repeated.

[0069] The array substrate and display device provided by the embodiments of the present disclosure include: a base substrate; a plurality of touch lines located on the base substrate; a touch electrode layer located on the side of the layer where each touch line is located away from the base substrate, the touch electrode layer includes a plurality of touch electrodes, and each touch electrode has a hollow area at the position of each touch line. Since each touch line is located in the hollow area of ​​the touch electrode, overlap between the touch electrode layer and each touch line is avoided, thereby reducing the coupling capacitance between the touch line and the touch electrode layer, and improving the touch accuracy.

[0070] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the embodiments of the present invention. Thus, if these modifications and variations of the embodiments of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
