Referring to fig. 1, an embodiment of the present invention provides an array substrate, including a plurality of pixel electrodes 3 disposed on a substrate 1 in an array, an insulating layer 40 disposed on the pixel electrodes 3, and a common electrode layer disposed on the insulating layer 40, where the common electrode layer includes a plurality of common electrodes 4 multiplexed as touch electrodes, and a plurality of touch signal lines 5 correspondingly connected to the touch electrodes; the orthographic projection of the touch signal line 5 on the base substrate 1 covers the gap area 8 between the pixel electrodes 3.
The array substrate provided by the embodiment of the invention comprises a plurality of pixel electrodes which are arranged on a substrate and distributed in an array manner, an insulating layer arranged on the pixel electrodes, and a common electrode layer arranged on the insulating layer, wherein the common electrode layer comprises a plurality of common electrodes which are multiplexed as touch electrodes, and a plurality of touch signal lines correspondingly connected with the touch electrodes; in the embodiment of the invention, the orthographic projection of the touch signal line on the substrate covers the gap area between the pixel electrodes, namely, the touch signal line and the common electrode are arranged on the same layer and are positioned above the pixel electrode layer, and the projection covers the gap area between the adjacent pixel electrodes, so that when in display, different signals are loaded on the pixel electrodes and the common electrode, an electric field for controlling the deflection of liquid crystal molecules can be formed between the touch signal line and the pixel electrodes around the touch signal line, and further the periphery of the touch signal line can be transparent; the problems that when the touch signal line is arranged on other layers, for example, when the touch signal line and the data line are on the same layer, because the touch signal line and the common electrode are loaded with the same signal during display, an electric field cannot be formed around the touch signal line, and the electric field between the touch signal line and the pixel electrode is shielded by the common electrode above, so that the electric field cannot be formed around the touch signal line, and the touch display panel can form a dark area around the touch signal line and has low transmittance can be solved.
In a specific implementation, the touch electrodes in the embodiments of the present invention may be self-contained touch electrodes, the touch signal lines may be connected to the touch electrodes in a one-to-one correspondence manner, and each touch signal line may be connected to the touch electrode through a lap joint.
Fig. 2 shows a schematic diagram of simulation results of liquid crystal Voltage and Transmittance (VT) curves of dual gate integrated display driver (TDDI) products of the prior art design and the present invention design, S1 is the VT curve of the dual gate TDDI product of the prior art design, and S2 is the VT curve of the dual gate TDDI product of the present invention design, wherein the dual gate TDDI product of the present invention includes the array substrate provided in the embodiment of the present invention, and as can be seen from fig. 2, the transmittance of the display product of the present invention is higher than that of the display product of the prior art under the same voltage.
In practical implementation, referring to fig. 3, there is also an overlapping area between the orthographic projection of the touch signal line 5 on the substrate 1 and the orthographic projection of the pixel electrodes 3 on the two sides of the gap area 8 on the substrate 1. In the embodiment of the present invention, an overlapping region exists between the orthographic projection of the touch signal line 5 on the substrate base plate 1 and the orthographic projection of the pixel electrode 3 on the substrate base plate 1, which is more favorable for forming an electric field capable of controlling the liquid crystal deflection between the touch signal line 5 and the pixel electrode 3.
In specific implementation, referring to fig. 4, the array substrate according to the embodiment of the present invention further includes: and the data lines 2 are positioned between the substrate 1 and the layer where the pixel electrodes 3 are positioned, wherein the extending direction of the projection of the touch signal lines 5 on the substrate 1 is the same as the extending direction of the projection of the data lines 2 on the substrate 1. In specific implementation, a data line insulating layer 30 may be further disposed between the layer where the pixel electrode 3 is located and the layer where the data line 2 is located, a gate (not shown) may be further disposed between the layer where the data line 2 is located and the substrate 1, and a gate insulating layer 20 may be further disposed between the layer where the gate is located and the layer where the data line 2 is located. In the embodiment of the present invention, the extending direction of the touch signal line 5 is the same as the extending direction of the data line 2, so that it can be avoided that if the touch signal line and the data line are not in the same direction, the touch signal line and the data line are designed to be in the same direction as the gate, which may cause the following problems: at present, a gate touch IC is not available, only a data touch IC is available, and a new gate touch IC needs to be developed; if the data touch IC is continuously used, the touch signal needs to be led to the data direction, the width of a non-display area on the periphery of the panel is greatly increased, and the requirement of narrow-frame products cannot be met. In another embodiment, the pixel electrode 3 and the data line 2 can also be fabricated in the same layer.
In practical implementation, referring to fig. 4, the orthographic projection of the data line 2 on the substrate 1 is located in the gap area between the pixel electrodes 3; the touch signal line 5 and the data line 2 are located in different gap areas.
In specific implementation, the touch signal lines and the data lines are alternately arranged. That is, the array substrate provided by the embodiment of the present invention may be an array substrate driven by dual gate lines (dual gate), an in-plane touch pixel structure designed by the dual gate lines (dual gate) is provided, data lines and touch signal lines (Tx) are alternately present, pixel electrodes corresponding to each sub-pixel are separated from each other, and a common electrode in a region corresponding to the touch signal line (Tx) needs to be hollowed out to reduce a load.
In specific implementation, as shown in fig. 3 or fig. 4, overlapping areas of the pixel electrodes 3 on two sides of the gap region 8 and the touch signal lines 5 are the same. In the embodiment of the present invention, when an electric field is formed between the touch signal line 5 and the pixel electrode 3 to control the liquid crystal to deflect, the overlapping areas of the pixel electrodes 3 at the two sides of the gap region 8 and the touch signal line 5 are the same, so that the deflection degrees of the liquid crystal at the two sides of the touch signal line 5 are the same, and the brightness degrees at the two sides of the touch signal line are the same.
In specific implementation, the overlapping area of each pixel electrode 3 and the touch signal line 5 accounts for less than 4.2% of the total area of the pixel electrode 3, i.e., less than 4.2%. In the embodiment of the present invention, the overlapping area of each pixel electrode 3 and the touch signal line 5 accounts for less than 4.2% of the total area of the pixel electrode 3, so as to avoid affecting the control of the pixel electrode 3 on the liquid crystal deflection in the pixel area during the display when the overlapping area of the touch signal line 5 and the pixel electrode 3 is too large.
In specific implementation, the line width of the touch signal line 5 is greater than the line width of the data line 2. In the embodiment of the present invention, the touch signal line 5 and the common electrode 4 are disposed on the same layer, the touch signal line 5 may be made of the same material as the common electrode 4, and since the common electrode 4 is generally made of Indium Tin Oxide (ITO), the touch signal line 5 in the embodiment of the present invention is also made of Indium Tin Oxide (ITO). In addition, in the dual gate display panel of the prior art, the touch signal line 5 and the data line 2 are generally disposed on the same layer and are generally made of metal, but in the embodiment of the present invention, considering that the ITO has a larger resistivity than metal, in order to avoid the problem that the touch signal line 5 made of ITO has a larger resistivity and may generate signal delay, the line width of the touch signal line 5 in the embodiment of the present invention is larger than the line width of the data line 2.

In specific implementation, the width of the black matrix 7 is the same as the line width of the touch signal line 5. In the prior art, the data line or other signal lines are generally made of metal, the black matrix is generally used for shielding the data line or other signal lines, and in order to prevent deviation during alignment, the line width of the black matrix covering the data line or signal line is further designed, that is, for example, the area of the black matrix at the corresponding position of the data line is larger than that of the data line, in the embodiment of the present invention, when the touch signal line is made of indium tin oxide, the black matrix does not mainly shield the touch signal line, and the width of the black matrix 7 can be set to be the same as the line width of the touch signal line 5.
