It should be readily understood by those skilled in the art that the embodiments and the contents can be changed into various forms without departing from the spirit and scope of the present disclosure. Therefore, the present disclosure should not be interpreted as being limited to the contents described in the embodiments below. The embodiments in the present disclosure and the features in the embodiments can be arbitrarily combined so long as there is no conflict. In order to keep the following description of the embodiments of the present disclosure clear and concise, detailed description of some known functions and known components will be omitted. The drawings of the embodiments of the present disclosure only involve structures related to the embodiments of the present disclosure, and other structures can be referred to the generally designed structures

[0075] The scale of the drawings in the present disclosure can be used as a reference in the actual process, but is not limited thereto. For example, the thickness and interval of each film layer, the width and interval of each signal line, can be adjusted according to the actual situation. The drawings described in the present disclosure are only schematic diagrams of structures, and one embodiment of the present disclosure is not limited to the shapes or values shown in the drawings.

[0076] In the present specification, ordinal numbers such as "first", "second", "third", and the like are provided in order to avoid confusion of components, and are not intended to be limiting in terms of number.

[0077] In the present specification, words indicating orientation or positional relationship such as "middle", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like are used to describe the positional relationship of the components with reference to the drawings, and are only for the convenience of describing the present specification and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present disclosure. The positional relationship of the components is appropriately changed according to the direction of each component. Therefore, it is not limited to the words described in the specification, and can be appropriately changed according to the situation.

[0078] In this specification, unless otherwise explicitly specified and limited, the terms "mount", "connected", "connected" should be understood broadly. For example, it can be fixedly connected, or detachably connected, or integrally connected; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate, or communication between two elements inside. For those skilled in the art, the specific meaning of the above terms in this disclosure can be understood according to the specific circumstances.

[0079] In this specification, "electrically connected" includes the case where the constituent elements are connected together through an element having some electrical effect. The "element having some electrical effect" is not particularly limited as long as it can perform the transmission and reception of electrical signals between the connected constituent elements. Examples of the "element having some electrical effect" include not only electrodes and wiring, but also switching elements such as transistors, resistors, inductors, capacitors, other elements having one or more functions, and the like.

[0080] In this specification, "film" and "layer" can be interchanged. For example, "conductive layer" can be replaced by "conductive film" sometimes. Similarly, "insulating film" can be replaced by "insulating layer" sometimes.

[0081] In this disclosure, "about" means not strictly limited boundaries, allowing values within the range of process and measurement errors.

[0082] In this disclosure, "thickness" is the size of the film layer in the direction perpendicular to the substrate.

[0083] The capacitive on-cell type touch panel is mainly divided into mutual capacitance structure and self capacitance structure. The mutual capacitance structure is composed of driving electrodes and sensing electrodes overlapping or close to each other to form mutual capacitance, and the position is detected by the change of mutual capacitance. The self-capacitance structure is composed of touch electrodes and human body to form self-capacitance, and the position is detected by the change of self-capacitance. The self-capacitance touch panel is a single-layer structure, which has the characteristics of low power consumption and simple structure. The mutual capacitance touch panel is a multi-layer structure, which has the characteristics of multi-point touch.

[0084] In an exemplary embodiment, the touch display device can include a display substrate disposed on a substrate and a touch panel disposed on the display substrate. The display substrate can be a liquid crystal display (LCD) substrate, or can be an organic light emitting diode (OLED) display substrate, or can be a plasma display device (PDP) display substrate, or can be an electrophoretic display (EPD) display substrate. In an exemplary embodiment, the display substrate is an OLED display substrate, which can include a substrate, a driving circuit layer disposed on the substrate, a light emitting structure layer disposed on the driving circuit layer, and an encapsulation layer disposed on the light emitting structure layer. The touch panel is disposed on the encapsulation layer of the display substrate, forming a Touch on Thin Film Encapsulation (Touch on TFE) structure, and the display structure and the touch structure are integrated together, having the advantages of thinness, foldability, etc., and can meet the product requirements of flexible folding, narrow frame, etc.

[0085] Currently, the Touch on TFE structure mainly includes a flexible multi-layer on cell (FMLOC) structure and a flexible single-layer on cell (FSLOC) structure. The FMLOC structure is based on the working principle of mutual capacitance detection, generally uses two layers of metal to form a driving (Tx) electrode and a sensing (Rx) electrode, and an integrated circuit (IC) detects the mutual capacitance between the driving electrode and the sensing electrode to realize touch action. The FSLOC structure is based on the working principle of self-capacitance (or voltage) detection, generally uses a single layer of metal to form a touch electrode, and an integrated circuit detects the self-capacitance (or voltage) of the touch electrode to realize touch action.

The touch signal lines 102 can electrically connect the touch sensing blocks 101 to the touch control circuit 103. When touch is performed, a touch object (for example, a human finger) touches the touch area 100 of the touch display device, and the capacitance of the touched touch sensing block 101 changes. The touch control circuit 103 is configured to determine the touch position by detecting the change in self-capacitance of the touch sensing block 101.

[0088] In an example embodiment, as shown in FIG. 2, the display area AA can include a plurality of data lines DL and a plurality of gate lines GL disposed on a substrate. The plurality of gate lines GL can extend along a first direction X and be arranged in sequence along a second direction Y different from the first direction X.

The area defined by the intersection of adjacent data lines DL and adjacent gate lines GL can be a sub-pixel area. One sub-pixel can be disposed in the sub-pixel area.

The non-opening area can be an area blocked by a black matrix of an opposite substrate of the array substrate, and the opening area can be an area not blocked by the black matrix of the opposite substrate. The adjacent gate lines GL and data lines DL can be located in the non-opening area. The array substrate of the embodiments of the present disclosure can be used to implement display functions, and the opening area of each sub-pixel area can be configured to display.

The second electrodes of the plurality of sub-pixels of the display area AA can be of an integral structure. For example, the second electrode can be located on the side of the first electrode 10 away from the substrate. The sub-pixel can further include a transistor 30.

The structure of the transistors located in the second frame area B2 can be the same as or different from the structure of the transistors located in the display area AA.

[0092] Most touch display products adopt a single Gate structure, in which a scanning signal line is arranged between two adjacent rows of pixels, and a data signal line provides a data signal to one column of sub-pixels. Since an in-cell touch screen needs to display signals and touch signals, a relatively large number of data driving chips (driving ICs) are needed, and the data driving chips are usually expensive, resulting in a relatively high cost of the in-cell touch display panel. The in-cell touch display product of a dual Gate structure can reduce the number of driving ICs and reduce the cost to some extent. In the dual Gate structure, two scanning signal lines are arranged between two adjacent rows of pixels, and a data signal line can provide a data signal to two adjacent sub-pixels in a row of sub-pixels. In the touch display panel of the dual Gate structure, there is a technical problem of vertical stripe defects in the effective area, for example, vertical stripes easily occur at a fixed position in the effective area of the touch display panel, the vertical stripes are lighter on the side (i.e., the side away from the bonding area 200) of the effective area close to the data pad (DP), and the vertical stripes are heavier on the side (i.e., the side close to the bonding area 200) of the effective area close to the data pad opposite (DPO). In some cases, the vertical stripe phenomenon disappears at a position about 1 / 4 of the length of the effective area on the side of the effective area close to the DPO in the second direction D2.

[0098] The plurality of touch sensing structures 101 can include at least one first touch sensing structure 1011 and a plurality of second touch sensing structures 1012, the first touch sensing structure 1011 corresponds to L1 adjacent touch base units R0, one first base unit R1 or one second base unit R2 located on one side of the L1 touch base units R0, the second touch sensing structure 1012 corresponds to L2 adjacent touch base units R0, L1, L2, U1, and U2 are positive integers.

[0099] The orthographic projection of the touch sensing structure 101 on the substrate can at least partially overlap the orthographic projection of the corresponding data line DL on the substrate.

[0100] In an example embodiment, the M data lines in the first base unit R1 pull the potential of the corresponding touch sensing structure 101 to 0, and the M data lines in the second base unit R2 pull the potential of the corresponding touch sensing structure 101 to 0, that is, the first base unit R1 and the second base unit R2 have no effect on the potential change of the corresponding touch sensing structure, which can avoid the phenomenon of vertical lines caused by the potential pull of the data lines on the touch sensing structure 101.

[0101] In an example embodiment, the first base unit R1 and the second base unit R2 can be arranged alternately along the row direction X.

Generally, one touch sensing structure 101 can correspond to 10 to 80 pixel units P0 in two columns of pixel unit columns, i.e., the orthogonal projection of one touch sensing structure 101 on the substrate can overlap with the orthogonal projection of 10 to 80 pixel units P0 in two columns of pixel units on the substrate, and FIG. 4 shows that one touch sensing structure 101 corresponds to 16 pixel units.

[0111] In an example embodiment, as shown in FIG. 5, a schematic diagram of the planar structure of a touch display substrate of a Dual Gate structure, two gate lines GLn (n is a positive integer) can be arranged between two adjacent rows of sub-pixels, each gate line GLn is arranged to be electrically connected with one of the adjacent rows of sub-pixels and to provide a scan signal to the row of sub-pixels connected therewith; in the row direction X, the data line DLm (m is a positive integer) and the touch signal line 102 can be located on both sides of one column of sub-pixels, each data line DLm can be located between two adjacent columns of sub-pixels, and each touch signal line 102 can be located between two adjacent columns of sub-pixels; each data line DLm is electrically connected with two adjacent columns of sub-pixels and is arranged to provide a data signal to the two columns of sub-pixels connected therewith, and at least part of the touch signal lines 102 are electrically connected with the corresponding touch sensing structures 101 through the vias VTx. In the structure shown in FIG. 5, one touch sensing structure 101 can overlap with the orthogonal projection of at least part of the pixel units P0 in six columns of pixel units P0 on the substrate.

[0112] In an example embodiment, as shown in FIG. 5, at least part of the data line DLm can include a data line body part ZDL and a first bending structure ZL1 connected with the data line body part ZDL, and at least part of the touch signal line 102 can include a touch signal line body part 1021 and a second bending structure ZL2 connected with the touch signal line 102; the data line body part ZDL can extend along the column direction Y and be located between two adjacent columns of sub-pixels, and be arranged to be electrically connected with the sub-pixels in at least one row among the two adjacent columns of sub-pixels; the first bending structure ZL1 can bend around at least one row of sub-pixels among the two adjacent columns of sub-pixels in the opposite direction of the first direction (i.e. the row direction) X, and at least part of the first bending structure ZL1 can be located between the two adjacent columns of sub-pixels and be arranged to be electrically connected with the two adjacent columns of sub-pixels; in the same data line DLm, at least one end of the first bending structure ZL1 is connected with the data line body part ZDL in the column direction Y; the touch signal line body part 1021 can extend along the column direction Y and be located between two adjacent columns of sub-pixels, and the second bending structure ZL2 can bend around at least one row of sub-pixels among the two adjacent columns of sub-pixels in the opposite direction of the first direction (i.e. the row direction) X, and at least part of the second bending structure ZL2 can be located between the two adjacent columns of sub-pixels; in the same touch signal line 102, at least one end of the second bending structure ZL2 is connected with the touch signal line body part 1021 in the column direction Y.

[0113] In an example embodiment, as shown in FIG. 5, the first bending structure ZL1 can include a first data structure part ZL11, a second data structure part ZL12, and a third data structure part ZL13. In the column direction Y, the first data structure part ZL11 and the third data structure part ZL13 can be located on both sides of at least one row of sub-pixels in two columns of sub-pixels bypassed by the first bending structure ZL1, and the two ends of the second data structure part ZL12 are connected with the first data structure part ZL11 and the third data structure part ZL13 respectively. The other end of the first data structure part ZL11 and the third data structure part ZL13 can be connected with the data line main part ZDL. In the row direction X, the second data structure part ZL12 can be located between the two adjacent columns of sub-pixels and be arranged to be electrically connected with at least one row of sub-pixels in the two adjacent columns of sub-pixels. The second bending structure ZL2 can include a first touch structure part ZL21, a second touch structure part ZL22, and a third touch structure part ZL23. In the column direction Y, the first touch structure part ZL21 and the third touch structure part ZL23 can be located on both sides of at least one row of sub-pixels in two columns of sub-pixels bypassed by the second bending structure ZL2, and the two ends of the second touch structure part ZL22 are connected with the first touch structure part ZL21 and the third touch structure part ZL23 respectively. The other end of the first touch structure part ZL21 and the third touch structure part ZL23 can be connected with the touch signal line main part 1021. In the row direction X, the second touch structure part ZL22 can be located between the two adjacent columns of sub-pixels.

[0114] In an example embodiment, as shown in FIG. 5, the first bending structure ZL1 bends in the opposite direction of the first direction X to bypass at least one row of sub-pixels in the two columns of sub-pixels, which can be consistent with the second bending structure ZL2 bending in the opposite direction of the first direction X to bypass at least one row of sub-pixels in the two columns of sub-pixels. For example, the first bending structure ZL1 and the second bending structure ZL2 both bypass one row of sub-pixels in the two columns of sub-pixels in the opposite direction of the first direction X, and the rows of sub-pixels bypassed by the first bending structure ZL1 and the second bending structure ZL2 are consistent. In an example embodiment, as shown in FIG. 5, the rows of sub-pixels bypassed by the first bending structure ZL1 and the second bending structure ZL2 can be the same, for example, the first bending structure ZL1 and the second bending structure ZL2 bypass even rows of sub-pixel rows, and odd rows of sub-pixel rows are not bypassed by the first bending structure ZL1 and the second bending structure ZL2.

[0115] In an example embodiment, as shown in FIGS. 5-7, the plurality of sub-pixels form a plurality of pixel units P0, which can be arranged in an array, each pixel unit P0 can include three sub-pixels (i.e., M is 3), the three sub-pixels in the same pixel unit can be arranged in sequence along the row direction X, and the orthogonal projection of each touch sensing structure 101 on the substrate can overlap with the orthogonal projection of at least part of the sub-pixels in the 18 columns of sub-pixels on the substrate, i.e., N can be 18, that is, in the row direction X, each touch sensing structure 101 can correspond to at least part of the pixel units in 6 columns of complete pixel units. Generally, one touch sensing structure 101 can correspond to 10 to 80 pixel units P0 in 6 columns of pixel unit columns, i.e., the orthogonal projection of one touch sensing structure 101 on the substrate can overlap with the orthogonal projection of 10 to 80 pixel units P0 in 6 columns of pixel units on the substrate. FIGS. 5 and 6 show that one touch sensing structure 101 corresponds to 36 pixel units P0 in 6 columns of pixel units, which can make the width of one touch sensing structure 101 in the row direction and the column direction approximately the same.

[0116] In an example embodiment, generally, as shown in FIG. 7, one touch sensing structure 101 can correspond to 6w data lines DLm, that is, in the row direction X, the orthogonal projection of one touch sensing structure 101 on the substrate can at least partially overlap with the orthogonal projection of 6w data lines DLm on the substrate, w is a positive integer, and in FIG. 7, one touch sensing structure 101 corresponds to 6 data lines DLm (DL1 to DL6), that is, w is 1. It should be noted that the correspondence between one touch sensing structure 101 and 6 data lines DL shown in FIG. 7 is for example, generally, one touch sensing structure 101 corresponds to about 40 pixel units PO, and the number of data lines DL corresponding to one touch sensing structure is generally more than 6, and in an actual structure, the number of data lines DL corresponding to one touch sensing structure 101 can be determined according to the size of the touch sensing structure 101 and the touch accuracy, as long as one touch sensing structure 101 corresponds to 6w data lines DL. As shown in FIGS. 5 and 6, in the case that the number of data lines DLm corresponding to one touch sensing structure 101 in the row direction X is not an integer multiple of 6, the touch sensing structure 101 in the touch display substrate can include one or more first touch sensing structures 1011, and the number of first touch sensing structures 1011 can be divided according to the specific structure. In an example embodiment, in the plurality of data lines DL in the touch display substrate, 6 data lines can be taken as one basic period, and the 6 data lines in one basic period can include first data line DL1 to sixth data line DL6 arranged in sequence along the row direction X (that is, m can be 1 to 6), in the row direction X, one first touch sensing structure 101 can correspond to adjacent L1 touch base units R0, one first base unit R1 or one second base unit R2 located on one side of the L1 touch base units R0, and one second touch sensing structure 1012 can correspond to adjacent L2 touch base units R0. One touch base unit R0 can include first base unit R1 and second base unit R2 arranged in sequence along the row direction X, or one touch base unit R0 can include first base unit R1 and second base unit R2 arranged in reverse sequence along the row direction X. That is, as shown in FIGS. 5 and 6, in the case that the number of data lines DLm corresponding to one touch sensing structure 101 is not an integer multiple of 6, one first touch sensing structure 1011 can correspond to adjacent L1*6+3 data lines DLm, and one second touch sensing structure 1012 can correspond to adjacent L2*6 data lines DLm, L1 and L2 are both positive integers. In an example embodiment, L1 and L2 have the same value, so that the sizes of the plurality of touch sensing structures 101 are substantially consistent.

[0117] In the example embodiment, the first touch sensing structure 1011 shown in FIG. 5 comprises a complete structure, and the first touch sensing structure 1011 and the second touch sensing structure 1012 shown in FIG. 6 comprise complete structures. It should be noted that the number of data lines DL corresponding to one touch sensing structure 101 shown in FIG. 3, FIG. 5 and FIG. 6 is for the purpose of illustrating the correspondence between the touch sensing structure 101 and the data line DL. In general, one touch sensing structure 101 corresponds to about 40 pixel units PO, and the number of data lines DL corresponding to one touch sensing structure is generally more than 6. In actual structures, the number of data lines DL corresponding to one touch sensing structure 101 can be determined according to the size of the touch sensing structure 101 and the touch precision, so that one touch sensing structure 101 corresponds to an integer multiple of the touch base period R0, or one touch sensing structure 101 corresponds to an integer multiple of the touch base period R0 and one of the first base unit R1 and the second base unit R2.

[0118] In the example embodiment, as shown in FIG. 5 and FIG. 6, each data line DLm is electrically connected to two adjacent columns of sub-pixels. One first touch sensing structure 1011 corresponds to L1 touch base units R0, one first base unit R1 or one second base unit R2 located on one side of the L1 touch base units R0. Then, one first touch sensing structure 1011 corresponds to 6L1*2+3*2 columns of sub-pixels. In the row direction X, the orthographic projection of one first touch sensing structure 1011 on the substrate can at least partially overlap with the orthographic projection of at least part of the 6L1*2+3*2 columns of sub-pixels on the substrate. As shown in FIG. 5 and FIG. 6, when L1 is 1, the orthographic projection of one first touch sensing structure 1011 on the substrate can at least partially overlap with the orthographic projection of at least part of the 6*1*2+3*2 columns of sub-pixels (i.e., 18 columns of sub-pixels) on the substrate.

[0119] In the example embodiment, as shown in FIG. 5 and FIG. 6, each data line DLm is electrically connected to two adjacent columns of sub-pixels. In the row direction X, one second touch sensing structure 1012 corresponds to 6L2 data lines in L2 touch base units R0. Then, one second touch sensing structure 1012 corresponds to 6L2*2 columns of sub-pixels. In the row direction X, the orthographic projection of one second touch sensing structure 1012 on the substrate can at least partially overlap with the orthographic projection of at least part of the 6L2*2 columns of sub-pixels on the substrate. As shown in FIG. 5 and FIG. 6, when L2 is 1, the orthographic projection of one second touch sensing structure 1012 on the substrate can at least partially overlap with the orthographic projection of at least part of the 6*1*2 columns of sub-pixels (i.e., 12 columns of sub-pixels) on the substrate.

[0120] In an example embodiment, as shown in FIGS. 4-6, one pixel unit P0 can include a first sub-pixel P01, a second sub-pixel P02, and a third sub-pixel P03. In an example embodiment, the first sub-pixel P01 can be a sub-pixel emitting red light, the second sub-pixel P02 can be a sub-pixel emitting green light, and the third sub-pixel P03 can be a sub-pixel emitting blue light.

[0125] In the exemplary embodiments, as shown in FIG. 9a, in the reverse direction of the row direction X, the first data line corresponding to the first touch sensing structure 101 can be the fifth data line DL5, and the second data structure part of the first data line DL5 is configured to be electrically connected with the first column of sub-pixels and the second column of sub-pixels corresponding to the first touch sensing structure 101.

[0126] In the exemplary embodiments, as shown in FIGS. 5 to 8a and 9a, in the case of the 127 gray scale of the green screen, in the six data lines in one base period, the first data line DL1, the third data line DL3 and the fifth data line DL5 can be configured to provide a high level signal (i.e. a positive signal), and the second data line DL2, the fourth data line DL4 and the sixth data line DL6 can be configured to provide a low level signal (i.e. a negative signal). In the case of other screens, the data signals can be provided to the first data line DL1 to the sixth data line DL6 according to the actual gray scale value, and the adjacent two data lines DL can provide the same signal or different signals (i.e. opposite polarities).

[0127] In the exemplary embodiments, as shown in FIGS. 3, 5-7, in the row direction X, each data line DL is electrically connected with four adjacent columns of sub-pixels, each second data structure part ZL12 is electrically connected with a row of sub-pixels in one of the two adjacent columns of sub-pixels, and the data line main part ZDL between the two adjacent first bending structure ZL1 in the column direction Y is electrically connected with a row of sub-pixels in the other two adjacent columns of sub-pixels;

[0128] In the first data line DL1 and the fourth data line DL4, the data line main part ZDL of each data line DL is electrically connected with one adjacent second sub-pixel column and one adjacent first sub-pixel column, and the second data structure part ZL12 of each data line is electrically connected with one adjacent third sub-pixel column and one adjacent second sub-pixel column;

[0129] In the second data line DL2 and the fifth data line DL5, the data line main part ZDL of each data line is electrically connected with one adjacent first sub-pixel column and one adjacent third sub-pixel column, and the second data structure part ZL12 of each data line is electrically connected with one adjacent second sub-pixel column and one adjacent first sub-pixel column;

[0130] In the third data line DL3 and the sixth data line DL6, the data line main part ZDL of each data line is electrically connected with one adjacent third sub-pixel column and one adjacent second sub-pixel column, and the second data structure part ZL12 of each data line is electrically connected with one adjacent first sub-pixel column and one adjacent third sub-pixel column.

[0131] In the exemplary embodiments, the pixel unit P0 includes three types of sub-pixels, i.e., the first sub-pixel P01, the second sub-pixel P02, and the third sub-pixel P03; in the first data line DL1, the second data line DL2, the fourth data line DL4, and the fifth data line DL5, the two adjacent sub-pixels in the sub-pixels connected by each data line are different types of sub-pixels; and in the third data line DL3 and the sixth data line DL6, two second sub-pixels are arranged between the adjacent first sub-pixel and the second sub-pixel in the sub-pixels connected by each data line.

[0132] In the exemplary embodiments, in the first data line DL1 and the fourth data line DL4, the number of the second sub-pixels P02 connected by each data line is equal to the sum of the number of the first sub-pixels P01 and the number of the third sub-pixels P03 connected by each data line; in the second data line DL2 and the fifth data line DL5, the number of the first sub-pixels P01 connected by each data line is equal to the sum of the number of the second sub-pixels P02 and the number of the third sub-pixels P03 connected by each data line; and in the third data line DL3 and the sixth data line DL6, the number of the third sub-pixels P03 connected by each data line is equal to the sum of the number of the first sub-pixels P01 and the number of the second sub-pixels P02 connected by each data line.

[0133] In the exemplary embodiments, as shown in FIGS. 4-7, the shape of the touch sensing structure 101 can be rectangular or square, and the length of the side of the touch sensing structure 101 is about 3-7 mm; in the structure supporting active pen touch and finger touch, the length of the side of the touch sensing structure 101 is about 3-6 mm; in the structure supporting only finger touch, the length of the side of the touch sensing structure 101 is about 4-7 mm. In the touch display substrate of the single-gate structure shown in FIG. 4, each touch sensing structure includes a complete pixel unit P0 in the row direction X, the number of data lines DL corresponding to one touch sensing structure 101 is an integer multiple of 3, and the number of pixel units P0 corresponding to one touch sensing structure 101 is about 10-80. In the touch display substrate of the double-gate structure shown in FIG. 7, the number of data lines DL corresponding to one touch sensing structure 101 is an integer multiple of 6 (i.e., an integer multiple of one base period, and the data lines of one base period and an integer multiple of one base period will not pull the potential of the corresponding touch sensing structure 101); in the touch display substrate of the double-gate structure shown in FIGS. 5 and 6, in the case where the number of data lines DLm corresponding to one touch sensing structure 101 is not an integer multiple of 6, 3 data lines DL can be added on the basis of an integer multiple of 6, for example, the first touch sensing structure 1011 can correspond to L1 adjacent touch base units R0, one first base unit R1 or one second base unit R2 located on one side of the L1 touch base units R0; the data lines corresponding to the second touch sensing structure 1012 correspond to L2 adjacent touch base units R0. The waveforms of the 6 data lines DL in one base period can be as shown in FIG. 10a, the pulling of the sixth data line DL6, the first data line DL1, and the second data line DL2 (i.e., one second base unit R2) on the touch sensing structure 101, and the pulling of the third data line DL3 to the fifth data line DL5 (i.e., one first base unit R1) on the touch sensing structure 101 can be as shown in FIG. 10b, which is a schematic diagram of the pulling of the data lines DL on the touch sensing structure at the M position in FIG. 10a. In FIG. 10b, +1 is the rising edge pulling, -1 is the falling edge pulling, and 0 is no pulling. The total pulling result Total of the first data line DL1, the second data line DL2, and the sixth data line DL6 on one touch sensing structure 101 is 0, and the total pulling result Total of the third data line DL3 to the fifth data line DL5 on one touch sensing structure 101 is 0, which can avoid the generation of vertical stripe defects due to the potential pulling of the data lines DL on the touch sensing structure 101 at the L127 gray scale of the pure green picture.

[0134] In the exemplary embodiments, the plurality of touch sensing structures 101 in FIG. 10c can include twelve sub-block modes S1-S12, in which the number of pixel units P0 corresponding to each touch sensing structure in the sub-blocks S1-S12 can be as shown in Table 1:

[0135] Table 1: Number of pixel units corresponding to touch sensing structure

[0136] In the plurality of division modes of the touch sensing structure 101 shown in FIG. 10c, in the effective area (which can overlap with the display area), the vertical lines are lighter on the side close to the data pad (DP) (i.e. the side close to the binding area 200), and the vertical lines are heavier on the side close to the opposite data pad (DPO) (i.e. the side away from the binding area 200). In some cases, in the column direction Y, the vertical line phenomenon disappears at a position about 1 / 4 of the length of the effective area on the side close to the DPO in the effective area. The vertical line defect mainly occurs on the sub-blocks S3, S4, S5, S6, S11, S12, i.e. each sub-block corresponds to 33 pixel units P0 or 34 pixel units P0 in the row direction X, and the vertical line mainly concentrates on the side close to the opposite data pad (DPO). The sub-blocks S1, S2, S7, S8, S9, S10 do not have vertical line defects, and in the sub-blocks S1, S2, S7, S8, S9, S10, each sub-block corresponds to 32 pixel units P0 in the row direction X. Generally, the division of the touch sensing structure 101 in the touch display substrate with double gate structure can adopt one or more of the twelve sub-block division modes shown in FIG. 10c according to the actual structure, and the reasons for the generation of vertical lines in the touch display substrate with double gate structure will be analyzed in combination with FIG. 10d:

[0137] In the touch display substrate with the double-gate structure shown in FIG. 10d, the signal of each data line DL controls 2 columns of sub-pixels on the left and right, the polarity of two adjacent data lines DL is opposite, and each 6 data lines DL is a basic period (i.e. 4 column pixel units P0). When each touch sensing structure 101 corresponds to 34 pixel units P0 in the row direction X, the number of data lines DL in each touch sensing structure 101 is 34*3 / 2=51, and after being divided by 6, there are still 3 data lines DL. Under the L127 gray scale of the pure green picture, the waveforms of the first three data lines DL can be as shown in FIG. 10e, that is, only the signal of the G sub-pixel is a high flat signal. As can be seen from the four rows of G0 positions in the figure, the first row and the third row control the G sub-pixel, and the second row and the fourth row control the R pixel, so when displaying the green picture, the R sub-pixel and the B sub-pixel of the second row are turned off, and the pulling of the second row and the fourth row has no effect on the entire touch sensing structure 101. The pulling of the three data lines DL on the touch sensing structure 101 (i.e. the COM block) corresponding thereto is as shown in FIG. 10f, in which +1 represents a rising edge pull, -1 represents a falling edge pull, and 0 represents no potential pull. Therefore, under the green gray scale 127 picture, the pulling of the 3 data lines DL on the touch sensing structure 101 cannot be cancelled out, as shown in FIG. 10g. According to the reasoning in FIG. 10f, under the green picture display combined with the polarity of the data line DL, the first column and the second column of G sub-pixels are + signals (i.e. high level signals), and the data line DL signal pulls them again, so the charging of the two columns of pixels is not saturated, and they are displayed as dark, i.e. undercharging (no pre-charging: under the green picture, the R sub-pixel or the B sub-pixel of the previous row of the G sub-pixel is turned off, so no pre-charging is performed); the third column of G sub-pixels and the fourth column of G sub-pixels are - signals (i.e. low level signals), and the data line DL signal pulls them again, so the charging of the two columns of pixels is over-saturated, and they are displayed as bright, i.e. pre-charging. Therefore, when normally displaying the green picture L127 gray scale, obvious vertical stripes of bright and dark will appear, i.e. the touch sensing structure 101 corresponds to 34 pixel units in the row direction X, and vertical stripes will appear.

[0138] In an example embodiment, as shown in FIG. 11a, in the touch display substrate with single gate structure, one touch signal line 102 and the corresponding one touch sensing structure 101 can be electrically connected through one column of vias VTx, the column of vias VTx can include a plurality of vias VTx, the plurality of vias VTx can be respectively arranged in a plurality of sub-pixels of one column of sub-pixels on one side of the touch signal line 102, for example, in the row direction X, the plurality of vias VTx can be respectively arranged in a plurality of sub-pixels of one column of sub-pixels on the side of the touch signal line 102 away from the data line DL, the sub-pixel at the edge position close to the touch sensing structure 101 can not be provided with the via VTx, the number of the column of vias VTx corresponding to one touch sensing structure 101 can be 15 to 30. In an example embodiment, in the structure in which one touch sensing structure 101 and two touch signal lines 102 are electrically connected through the via VTx, a column of vias VTx can be arranged on each of the two touch signal lines 102, the sub-pixels where the two adjacent vias VTx on one touch signal line 102 are located can be spaced apart by at least one sub-pixel (for example, can be spaced apart by one sub-pixel) in the column direction Y, which can avoid the dense vias VTx causing the visually observable via point defect. In an example embodiment, as shown in FIG. 11b, in the case where one touch sensing structure 101 and two touch signal lines 102 are electrically connected through two columns of vias VTx, the two touch signal lines 102 can include a first touch signal line 102a and a second touch signal line 102b, the two columns of vias VTx can include a plurality of first vias VTx a in the first column of vias and a plurality of second vias VTx b in the second column of vias, the first touch signal line 102a can be electrically connected to the corresponding touch sensing structure 101 through the plurality of first vias VTx a in the first column of vias, the second touch signal line 102b can be electrically connected to the corresponding touch sensing structure 101 through the plurality of second vias VTx b in the second column of vias, the plurality of first vias VTx a and the plurality of second vias VTx b corresponding to one touch sensing structure 101 can be alternately arranged in the column direction Y, which can avoid the dense two columns of vias VTx causing the visually observable via point defect.

[0139] In the example embodiment, as shown in FIGS. 5 and 6, in the touch display substrate with the double-gate structure, the plurality of touch signal lines 102 and the plurality of data lines DL can extend along the column direction Y and be arranged along the row direction X, the touch signal lines are electrically connected to the corresponding touch sensing structures through a column of vias, and the plurality of data lines DL and the plurality of touch signal lines 102 can be alternately arranged along the row direction X; one touch sensing structure 101 can be electrically connected to at least one touch signal line 102 through at least one column of vias VTx, in the structure in which one touch sensing structure 101 is electrically connected to one of the touch signal lines 102 through one column of vias VTx, the number of touch signal lines 102 is reduced, and the transmittance of the touch display substrate can be improved. In the column direction Y, two sub-pixels in which two vias VTx adjacent to each other on one touch signal line 102 can be spaced apart by at least one sub-pixel in the column direction, and the dense vias VTx can be avoided to cause the via point defect that can be observed by the naked eye. In one touch sensing structure 101, 10 to 25 vias VTx in one column of vias can be electrically connected to the corresponding touch signal line 102, and no via VTx is arranged at the edge position of the touch sensing structure 101.

[0140] In the example embodiment, as shown in FIG. 12a, in the touch display substrate in which one touch sensing structure 101 is electrically connected to two touch sensing structures 101, the two touch signal lines 102 electrically connected to the same touch sensing structure 101 can include a first touch signal line 102a and a second touch signal line 102b, and the end portions of the first touch signal line 102a and the second touch signal line 102b close to the data binding end DP are short-circuited, that is, the end portions of the first touch signal line 102a and the second touch signal line 102b close to the data binding end DP are connected in parallel in the frame area, which can reduce the impedance of the touch signal line 102. In general, the parallel connection of the two touch signal lines 102 can reduce the impedance by half, which reduces the RC delay to a certain extent and improves the touch performance. As shown in FIG. 12a, after the end portions of the first touch signal line 102a and the second touch signal line 102b close to the data binding end DP are short-circuited, the short-circuit line 1020 is electrically connected to the driving chip (driving IC), receives the touch signal from the driving chip, and provides the touch signal to the corresponding touch sensing structure 101 through the first touch signal line 102a and the second touch signal line 102b. As shown in FIG. 12a, one end of the short-circuit line 1020 is electrically connected to the driving chip IC, and the other end is electrically connected to the first touch signal line 102a and the second touch signal line 102b. That is, as shown in FIG. 12a, the touch display substrate can include a display area AA and a data binding end DP located on one side of the display area, one touch sensing structure 101 in the display area AA is electrically connected to two touch signal lines through two columns of vias VTx, and the two touch signal lines 102 are connected in parallel at the end portions close to the data binding end DP.

[0141] In an example embodiment, as shown in FIG. 12b, at least part of the touch sensing structure 101 can correspond to at least one dummy touch signal line 50, a normal projection of the dummy touch signal line 50 on the substrate can at least partially overlap with a normal projection of the corresponding touch sensing structure 101 on the substrate, the touch sensing structure 101 can be electrically connected with the corresponding dummy touch signal line 50 (i.e. Dummy Tx trace) through the via VTx, the thickness of the touch sensing structure 101 can be increased, and the impedance of the touch sensing structure 101 can be reduced. In an example embodiment, the normal projection of the dummy touch signal line 50 on the substrate can be located within the range of the normal projection of the corresponding touch sensing structure 101 on the substrate. In an example embodiment, in the row direction X, the dummy touch signal line 50 can be arranged between the sixth data line DL6 and the first data line DL1 as shown in FIG. 5 and FIG. 6, i.e. the touch signal line 102 between the sixth data line DL6 and the first data line DL1 can be used as the dummy touch signal line 50. In the case that the touch signal line 102 is used as the dummy touch signal line 50, in the column direction Y, one touch signal line 102 can be divided into a plurality of dummy touch signal lines 50 corresponding to a plurality of touch sensing structures 101 respectively, and two adjacent dummy touch signal lines 50 in the column direction Y are disconnected. In an example embodiment, in the case that the number of touch signal lines is sufficient, the touch signal line 102 between the first data line DL1 can be used as the dummy touch signal line 50; in the case that the number of touch signal lines is insufficient, the touch signal line 102 between the sixth data line DL6 and the first data line DL1 is used as a touch signal line to provide a touch signal to the corresponding touch sensing structure 101.

[0142] In an example embodiment, as shown in FIG. 13, the touch signal line 102 can be located in the same conductive layer as the data line DL, the touch display substrate can include a source-drain metal layer (SD layer) and a touch layer, an insulating layer can be arranged between the source-drain metal layer and the touch layer, the touch sensing structure 101 can be located in the touch layer, and the touch layer can be reused as the common electrode layer of the touch display substrate; the data line DL and the touch signal line 102 can be located in the source-drain metal layer, and the touch signal line 102 can be electrically connected with the touch sensing structure 101 through the via VTx.

[0143] In an example embodiment, a partial enlarged schematic view of an amorphous silicon (A-Si) touch display substrate manufactured by six mask plates is shown in FIG. 13. The touch signal line 102 and the data line DL are located in the same conductive layer in FIG. 13, and there is a problem of low transmittance. In the case where it is necessary to provide a touch display product with transmittance, an additional conductive layer can be added as a touch signal line layer. The touch signal line layer is provided with the touch signal line 102, and the source-drain metal layer is provided with the data line DL. The orthographic projection of the touch signal line 102 and the corresponding data line DL on the substrate can at least partially overlap, thereby improving the transmittance of the touch display substrate. Oxide touch display substrates can be manufactured by nine mask plates. The oxide touch display substrate can include a first conductive layer, a first insulating layer (GI layer, which can be referred to as a gate medium layer), a semiconductor layer, a second conductive layer (which can be referred to as a source-drain metal layer, abbreviated as SD layer), a second insulating layer (PVX Buffer layer, which can be referred to as a first buffer layer), an organic film layer (ORG layer, which can be referred to as a planarization layer), a third insulating layer (PVX Buffer layer, which can be referred to as a second buffer layer), a third conductive layer, a fourth insulating layer (PVX Buffer layer, which can be referred to as a third buffer layer), a fourth conductive layer (ITO1 layer, which can be referred to as a COM layer or a common electrode layer), a fifth insulating layer (PVX layer, which can be referred to as a passivation layer), and a fifth conductive layer (ITO2 layer, which can be referred to as a pixel electrode layer or pixel layer), which are sequentially arranged on a substrate. In an example embodiment, a plurality of gate lines GL arranged in the column direction Y can be located in the first conductive layer. The semiconductor layer can include an active layer of a transistor 30. The active layer can be made of oxide, for example, indium gallium zinc oxide (IGZO) material. The data line DL can be located in the source-drain metal layer SD (i.e., the second conductive layer). The touch signal line 102 can be located in the third conductive layer. The common electrode layer can be multiplexed as a touch layer. The touch sensing structure 101 can be located in the touch layer. The second insulating layer to the fourth insulating layer do not require mask plates. Oxide touch display substrates can be formed by nine mask plates.

[0144] As shown in FIG. 14, which is a schematic view of a partial enlarged view of the oxide touch display substrate, the shape of the via VTx can be rectangular, the length e of the via VTx along the first direction X can be 6-12 microns, and the length f of the via VTx along the second direction Y can be 3-6 microns; the pixel electrode layer can include a plurality of transfer electrodes 60, the shape of the transfer electrode 60 can be rectangular, the via VTx corresponds to one of the transfer electrodes 60, and the orthographic projection of the via VTx on the substrate at least partially overlaps the orthographic projection of the corresponding transfer electrode 60 on the substrate; in an exemplary embodiment, as shown in FIG. 14, the orthographic projection of the via VTx on the substrate can be located within the range of the orthographic projection of the corresponding transfer electrode 60 on the substrate, the difference between the size of the transfer electrode 60 along the first direction X and the size of the corresponding via VTx along the first direction X is about 2 microns, the distance H1 between one edge of the transfer electrode 60 and the nearest edge of the corresponding via VTx along the first direction X is about 1 micron, the size of the transfer electrode 60 along the first direction X (i.e., the row direction) is greater than the size of the corresponding via VTx along the first direction X; the difference between the size of the transfer electrode 60 along the second direction Y (i.e., the column direction) and the size of the corresponding via VTx along the second direction Y is about 2 microns, the distance H2 between one edge of the transfer electrode 60 and the nearest edge of the corresponding via VTx along the second direction Y is about 1 micron, and the size of the transfer electrode 60 along the second direction Y is greater than the size of the corresponding via VTx along the second direction Y.
