Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless otherwise specified.

Further, in the present application, directional terms such as "upper", "lower", and the like may include, but are not limited to, being defined relative to a schematically-disposed orientation of components in the drawings, it being understood that these directional terms may be relative concepts that are intended for relative description and clarification, and that will vary accordingly depending on the orientation of the components in the drawings in which they are disposed.

In this application, unless expressly stated or limited otherwise, the term "coupled" is to be construed broadly, e.g., "coupled" may be directly or indirectly coupled through intervening media.

Some embodiments of the present application provide a display device. The display device may be, for example, a mobile phone, a tablet pc, a tv, a desktop pc, an intelligent wearable product (smart watch, bracelet), a Personal Digital Assistant (PDA), a car-mounted computer, or the like. The embodiment of the present application does not specifically limit the specific form of the display device.

In some embodiments of the present application, the display device may be a Liquid Crystal Display (LCD). As shown in fig. 1, the LCD mainly includes a display panel 01 and a backlight unit (BLU) 02. The display panel 01 includes an array substrate 10 and an opposite-box substrate 20, which are oppositely disposed, and a liquid crystal layer 30 located between the array substrate 10 and the opposite-box substrate 20. Wherein, a common electrode layer is disposed in the array substrate 10.

In the related art, as shown in fig. 2a, the array substrate 10 includes: a plurality of scan lines GL, a plurality of data lines DL, and a plurality of subpixel regions 101 defined by intersections of the scan lines GL and the data lines DL. Each sub-pixel region 101 is provided with: the driving transistor 1011 and the pixel electrode 1012, and the drain of the driving transistor 1011 is connected to the pixel electrode 1012. In addition, the array substrate 10 is further provided with a common electrode layer 102, and the common electrode layer 102 is arranged in a different layer from the scanning line GL.

In the related art, in order to implement the touch function, as shown in fig. 2b, the common electrode layer 102 needs to be divided into a plurality of common electrodes, and each common electrode is multiplexed as the touch electrode Tx. Meanwhile, in order to implement time-sharing control of touch and display, each touch electrode Tx needs to be supplied with a voltage signal through a separate touch signal line 103. The touch signal lines 103 provide touch sensing signals to the corresponding touch electrodes Tx during the touch detection phase and provide common voltage signals to the corresponding touch electrodes Tx during the display phase.

For example, in normal display, the touch signal line 103 outputs a common voltage (Vcom) to the common electrode, and outputs a touch detection square wave to detect a touch for a blank time between rows or between frames. The touch control and the display control are carried out in a time-sharing manner, so that the touch and display functions can be realized. Therefore, the touch electrode Tx is directly integrated in the display panel, so that the manufacturing cost is greatly reduced, the production efficiency is improved, and the panel thickness is reduced.

As shown in fig. 2b, when the common electrode is multiplexed as the touch electrode Tx, each touch electrode Tx overlaps a plurality of scan lines GL, so that a parasitic capacitance exists between the touch electrode Tx and each corresponding scan line GL. In the display stage, the touch electrode Tx receives a common voltage, and the scan lines GL are sequentially inputted with scan signals, and due to the parasitic capacitance, the common voltage of the common electrode is interfered, so that the voltage of the common electrode is easily pulled by the scan signals on the scan lines GL. The degree of coupling of the common electrode with the scanning lines GL is proportional to the number of scanning lines GL covered by the common electrode and simultaneously loaded with scanning signals.

The timing of the scanning signals inputted to the scanning lines GL is, for example, as shown in fig. 3, where Gsum is the number of scanning lines GL to which the scanning signals are inputted at each time. As shown in fig. 3, the scanning signals received by at most 4 scanning lines GL adjacent to each other in sequence have overlapping phases in time. However, for each touch electrode Tx, when the 1 st to 3 th scanning lines GL of the scanning lines GL corresponding to the touch electrode Tx are scanned and the 4 th scanning line is completed and the 3 rd to 1 st scanning line GL is scanned, only the scanning signals received by the 1 to 3 scanning lines GL have overlapping phases in time (for example, T1 and T3 phases in fig. 3), which results in different degrees of coupling of the common voltage at the edge and the middle along the data line DL direction (for example, Txc in fig. 3) for the single touch electrode Tx. The common voltage is pulled up to different degrees, which may cause a horizontal stripe phenomenon at the edge of the touch electrode Tx.

In view of this, some embodiments of the present disclosure provide an array substrate 10, as shown in fig. 4, the array substrate 10 has a display area 11 and a peripheral area 12.

The array substrate 10 includes a substrate 100, and a plurality of scan lines GL disposed on the substrate 100 and located in the display area 11, wherein the scan lines GL extend to the peripheral area 12 and are connected to the gate driving circuit 121. In the display stage, the gate driving circuit 121 is configured to sequentially output scanning signals to the plurality of scanning lines GL. Taking the high-level signal as the active signal, the high-level active signal received by each scan line GL lasts for a first fixed time, and the scan lines GL of the two adjacent scan lines GL receive the scan signals in a sequential order (for example, the scan lines extend along the horizontal direction, and the scan lines GL extend from top to bottom), and the scan signals received by the scan lines GL of the two adjacent scan lines GL last for a second fixed time, and the scan signals on the two adjacent scan lines GL overlap in time.

The array substrate 10 further includes a plurality of touch electrodes Tx, as shown in fig. 4, the touch electrodes Tx are arranged in n rows and m columns, and the touch electrodes Tx may be multiplexed as a common electrode. The touch electrodes Tx and the scanning lines GL are disposed in different layers, and along the extending direction of the scanning lines GL, the touch electrodes Tx in the same row overlap with the orthographic projections of the t scanning lines GL on the substrate 100. It can be understood that the t scanning lines GL corresponding to each row of the touch electrodes Tx are sequentially inputted with the scanning signal, after the last (t-th) scanning line GL of the previous row of the touch electrodes Tx is inputted with the scanning signal, the first scanning line GL of the next row of the touch electrodes Tx is inputted with the scanning signal, and so on.

Illustratively, as shown in fig. 4, the touch electrode Tx located in the first row₁₁～Tx_1mAnd t scanning lines GL₁₁～GL_1tOrthographic projection on the substrate 100 is overlapped, and the touch electrode positioned on the ith row is overlapped with the t scanning lines GL_i1～GL_itOrthographic projection on the substrate 100 is overlapped, and the touch electrode on the nth row is overlapped with the t scanning lines GL_n1～GL_ntThe orthographic projections on the substrate 100 overlap. T scanning lines GL corresponding to touch electrodes in the first row₁₁～GL_1tFrom the 1 st scanning line GL₁₁Starting to receive the scanning signals in sequence, when the t-th scanning line GL corresponding to the touch electrode in the first row_1tAfter receiving the scanning signal, the scanning signals are sequentially received from the 1 st scanning line, and so on, next to the t scanning lines corresponding to the touch electrodes in the second row.

Wherein n, m, t and i are positive integers, and i is more than or equal to 2 and less than or equal to n-1.

In this case, in some embodiments, a Touch and Display Driver Integration (TDDI) technology may be adopted to integrate the touch chip for controlling the touch sensing signal and the display chip for controlling the display signal into a single chip, so as to save cost.

In addition, the array substrate 10 further includes a plurality of first auxiliary line groups 13. As shown in fig. 4, the first auxiliary line group 13 includes at least one first auxiliary line 131. The ith row of touch electrodes Tx overlaps with the orthographic projections of the two first auxiliary line groups 13 on the substrate 100.

On this basis, as shown in fig. 4, in one of the first auxiliary line groups 13 corresponding to the ith row of touch electrodes Tx, at least one first auxiliary line 131 corresponds to and is electrically connected to at least one of the t-k th to t-th scanning lines GL corresponding to the ith-1 row of touch electrodes Tx. That is, one first auxiliary line group 13 of the two first auxiliary line groups 13 corresponding to the ith row of touch electrodes Tx includes at least one first auxiliary line 131, and the at least one first auxiliary line 131 is in one-to-one correspondence with and electrically connected to at least one of the last k +1 scanning lines GL of the scanning lines GL covered by the previous row of touch electrodes Tx.

In the other first auxiliary line group 13 corresponding to the ith row of touch electrodes Tx, at least one first auxiliary line 131 corresponds to and is electrically connected to at least one of the 1 st to k +1 th scanning lines GL corresponding to the (i + 1) th row of touch electrodes Tx. That is, the other first auxiliary line group 13 corresponding to the ith row of touch electrodes Tx includes at least one first auxiliary line 131, and the at least one first auxiliary line 131 is in one-to-one correspondence with and electrically connected to at least one of the first k +1 scanning lines GL in the scanning lines GL covered by the last row of touch electrodes Tx.

The number of the first auxiliary lines 131 in the first auxiliary line group 13 is less than or equal to k +1, and k is a positive integer.

It should be noted that, in fig. 4, it is illustrated that each first auxiliary line group 13 includes 2 first auxiliary lines 131, and in other embodiments, the first auxiliary line group may include 1 or more first auxiliary lines, which is not limited in this application as long as the number of the first auxiliary lines 131 is satisfied: it is preferably 1 or more and k +1 or less.

The scanning signals output by the gate driving circuit and sequentially received by any k +2 scanning lines which are sequentially adjacent have overlapping stages in time.

Taking k as an example, in 4 scan lines GL which are adjacent in sequence, the duration of the scan signal received by the 1 st scan line GL is t1-t2(t2-t1 ═ t0), the duration of the scan signal received by the 2 nd scan line GL is t3-t4(t3 is located between t1-t2, and t4-t3 ═ t0), the duration of the scan signal received by the 3 rd scan line GL is t 0-t 0 (t 0 is located between t 0-t 0, and t 0-t 0 ═ t0), and the duration of the scan signal received by the 4 th scan line GL is t 0-t 0 (t 0 is located between t 0-t 0, and t0 ═ t 0).

When k +2 scanning lines GL having temporally overlapping phases of the received scanning signals are located in an area covered by two adjacent rows of touch electrodes Tx, since at least one first auxiliary line 131 corresponds to at least one of the t-k to t-th scanning lines GL corresponding to the i-1 st row of touch electrodes Tx in one of the first auxiliary line groups 13 corresponding to the i-th row of touch electrodes Tx in a one-to-one correspondence and is electrically connected, and at least one first auxiliary line 131 corresponds to at least one of the 1 st to k +1 st scanning lines GL corresponding to the i +1 st row of touch electrodes Tx in the other first auxiliary line group 13 corresponding to the i-th row of touch electrodes Tx in a one-to-one correspondence and is electrically connected. Thus, when the t-k to t-th scanning lines GL corresponding to the i-1 th row of touch electrodes Tx are scanned, the first auxiliary line 131 in one of the first auxiliary line groups 13 corresponding to the i-1 th row of touch electrodes Tx can have a scanning signal thereon, and when the 1 st to k +1 th scanning lines GL corresponding to the i +1 th row of touch electrodes Tx are scanned, the first auxiliary line 131 in the other first auxiliary line group 13 corresponding to the i-th row of touch electrodes Tx can have a scanning signal thereon. Accordingly, when the scanning line GL receives a scanning signal at the edge of the touch electrode Tx, the number of signal lines coupled to the common electrode is increased, and a difference in the degree of coupling between the edge and the center Vcom is reduced, thereby improving the edge cross striation phenomenon through signal compensation of the first auxiliary line 131.

On this basis, in some embodiments of the present application, the first auxiliary line group 13 includes k +1 first auxiliary lines 131.

In one of the first auxiliary line groups 13 corresponding to the ith row of touch electrodes Tx, k +1 first auxiliary lines 131 are in one-to-one correspondence with and electrically connected to the t-k th to t-th scanning lines GL corresponding to the ith-1 row of touch electrodes Tx. That is, one first auxiliary line group 13 in the two first auxiliary line groups 13 corresponding to the ith row of touch electrodes Tx includes k +1 first auxiliary lines 131, and the k +1 first auxiliary lines 131 are in one-to-one correspondence with and electrically connected to the t-k th to t-th scanning lines GL in the scanning lines GL covered by the previous row of touch electrodes Tx.

In addition, in the other first auxiliary line group 13 corresponding to the ith row of touch electrodes Tx, k +1 first auxiliary lines 131 are in one-to-one correspondence with and electrically connected to the 1 st to k +1 th scan lines GL corresponding to the ith +1 row of touch electrodes Tx. That is, the other first auxiliary line group 13 corresponding to the ith row of touch electrodes Tx includes k +1 first auxiliary lines 131, and the k +1 first auxiliary lines 131 are in one-to-one correspondence with and electrically connected to the 1 st to k +1 th scanning lines GL in the scanning lines GL covered by the following row of touch electrodes Tx.

In one of the first auxiliary line groups 13 corresponding to the ith row of touch electrodes Tx, k +1 first auxiliary lines 131 are in one-to-one correspondence with and electrically connected to the t-k th to t-th scanning lines GL corresponding to the ith-1 row of touch electrodes Tx, and in the other first auxiliary line group 13 corresponding to the ith row of touch electrodes Tx, k +1 first auxiliary lines 131 are in one-to-one correspondence with and electrically connected to the 1 st to k +1 th scanning lines GL corresponding to the ith +1 row of touch electrodes Tx. In this way, when the k +2 scanning lines GL having temporally overlapping phases of the received scanning signals are located in the area covered by two adjacent rows of touch electrodes Tx, when the t-k th to t-th scanning lines GL corresponding to the i-1 th row of touch electrodes Tx are scanned, the scanning signal may be provided on the first auxiliary line 131 in one of the first auxiliary line groups 13 corresponding to the i-th row of touch electrodes Tx, and when the 1 st to k +1 th scanning lines GL corresponding to the i +1 th row of touch electrodes Tx are scanned, the scanning signal may be provided on the first auxiliary line 131 in the other first auxiliary line group 13 corresponding to the i-th row of touch electrodes Tx. Therefore, through the signal compensation of the first auxiliary line 131, when the scanning line GL at the edge of the touch electrode Tx receives a scanning signal, the number of the signal lines coupled with the common electrode is the same as that at the center of the touch electrode Tx, so that the difference of the degree of coupling between the edge and the center Vcom is further reduced, and the effect of improving the edge striation is improved.

In some embodiments of the present application, the first row of touch electrodes Tx may also overlap with the orthographic projections of the two first auxiliary line groups 13 on the substrate 100. And the k +1 first auxiliary lines 131 of one of the first auxiliary line groups 13 are in one-to-one correspondence with and electrically connected to the 1 st to the k +1 th scanning lines GL corresponding to the 2 nd row of touch electrodes Tx.

Since there is no corresponding previous row touch electrode Tx due to the first row touch electrode Tx, the k +1 first auxiliary lines 131 in the other first auxiliary line group 13 may be connected to the low voltage terminal (e.g., Vgl).

In addition, the touch electrode Tx in the last row (nth row) may also overlap with the orthographic projections of the two first auxiliary line groups 13 on the substrate 100. And the k +1 first auxiliary lines 131 of one of the first auxiliary line groups 13 are in one-to-one correspondence with and electrically connected to the t-k to t-th scanning lines GL corresponding to the touch electrodes Tx in the n-1 th row.

Since there is no subsequent row of touch electrodes Tx corresponding to the last row of touch electrodes Tx, the k +1 first auxiliary lines 131 in the other first auxiliary line group 13 are connected to the low voltage terminal (e.g., Vgl).

In some embodiments of the present application, the gate driving circuit 121 may be a Gate On Array (GOA) circuit. In the GOA circuit, the gate driving circuit 121 is directly fabricated in the peripheral region 12 of the array substrate 10, which can reduce the production cost and realize a narrow frame design. The GOA circuit comprises a plurality of sequentially cascaded GOA units, each GOA unit comprises a signal output end, the plurality of GOA units correspond to the plurality of scanning lines GL one by one, and the scanning lines GL in one-to-one correspondence are electrically connected with the signal output ends of the GOA units. In this case, the first auxiliary line 131 electrically connected to each scanning line GL may be electrically connected to an output terminal of the GOA cell corresponding to the scanning line GL, or the first auxiliary line 131 may be electrically connected to the corresponding scanning line GL in the peripheral region 12.

In addition, x clock Control Lines (CLK) connected to the GOA circuit are further disposed on the peripheral region 12 of the array substrate 10, and the clock control lines are used for transmitting clock signals to the gate driving circuit to control the output timing of the scan signals. The x clock control lines can provide x/2 pairs of clock signals with opposite phases, and at most, the scanning signals in the x/2 scanning lines GL can have overlapped phases in time. In this case, k satisfies the following relationship k +1 ═ x/2-1.

For example, when 8 clock signal lines are connected to the GOA circuit and 8 clock signals with different phases are provided, k +1 is equal to 3, and accordingly, the scanning signals output by the gate driving circuit sequentially received by any 4 sequentially adjacent scanning lines GL have overlapping phases in terms of time.

It is considered that, in addition to the influence of the parasitic capacitance between the scanning line GL and the touch electrode Tx, the parasitic capacitance Cgs existing between the gate and the source of the driving transistor 1011 also has an influence on the voltage pulling between the scanning line GL and the common electrode.

In this regard, in some embodiments of the present application, each of the scanning lines GL is electrically connected to the pixel circuits in one row of the sub-pixel region 101.

Applying a voltage to the scanning lines GL turns on the pixel circuits electrically connected to the scanning lines GL, so that the signal voltage on the data lines DL can be written into the pixel electrodes 1012, and the electric field formed by the pixel electrodes 1012 and the common electrode controls the deflection of the liquid crystal, thereby achieving the effect of different gray scales. On the basis, when a color film is provided on the opposing substrate 20, the light emitted from the liquid crystal layer 30 can be displayed in color by the color filter action of the color film.

In addition, each of the first auxiliary lines 131 is also connected to the pixel circuits in one row of the sub-pixel region 101, respectively.

On this basis, for the pixel circuit 110 connected to both the scanning line GL and the first auxiliary line 131, as shown in fig. 5a, the pixel circuit 110 includes a first switch sub-circuit 111 and a second switch sub-circuit 112.

As shown in fig. 5a, the first switch sub-circuit 111 is electrically connected to the scan line GL, the data line DL and the pixel electrode 1012, and the first switch sub-circuit 111 is configured to be turned on under the control of a scan signal from the scan line GL to transmit a data signal on the data line DL to the pixel electrode 1012.

The second switch sub-circuit 112 is electrically connected to the scanning line GL, the first auxiliary line 131, the data line DL, and the pixel electrode 1012, and the second switch sub-circuit 112 is configured to be turned on or off under control of a scanning signal from the scanning line GL and a scanning signal from the first auxiliary line 131.

In some embodiments, as shown in fig. 5b, the first switch sub-circuit 111 includes a first transistor M1, a gate of the first transistor M1 is electrically connected to the scan line GL, a first pole of the first transistor M1 is electrically connected to the data line DL, and a second pole of the first transistor M1 is electrically connected to the pixel electrode 1012.

The second switch sub-circuit 112 includes a second transistor M2 and a third transistor M3.

The gate of the second transistor M2 is electrically connected to the scan line GL, the first pole of the second transistor M2 is electrically connected to the data line DL, and the second pole of the second transistor M2 is electrically connected to the first pole of the third transistor M3.

A gate of the third transistor M3 is electrically connected to the first auxiliary line 131, and a second pole of the third transistor M3 is electrically connected to the pixel electrode 1012.

In this way, the first auxiliary line 131 provided in the embodiment of the present invention is also connected to the third transistor M3 located in the one row of sub-pixel regions 101, so that when the parasitic capacitance between the scanning line GL at the edge of the touch electrode Tx and the touch electrode Tx is compensated, the influence of the parasitic capacitance Cgs between the gate and the source of the driving transistor 1011 is also compensated.

On this basis, in order to keep the aperture ratio of each sub-pixel region 101 and the off-state current (Ioff) of the driving transistor 1011 consistent, the display unevenness of the entire display panel due to the addition of the second transistor M2 and the third transistor M3 to some sub-pixel regions 101 is avoided. Therefore, for the pixel circuit 110 connected to the scanning line GL without being connected to the first auxiliary line 131, as shown in fig. 5c, the pixel circuit 110 includes a first switching sub-circuit 111 and a third switching sub-circuit 113.

The third switching sub-circuit 113 is electrically connected to the scanning line GL, the data line DL, the second auxiliary line 132, and the pixel electrode 1012, and the third switching sub-circuit 113 is configured to maintain an off state under control of a scanning signal from the scanning line GL and a low voltage signal from the second auxiliary line 132.

Each second auxiliary line 132 is connected to the pixel circuits in one row of the sub-pixel region 101. In addition, the second auxiliary line 132 is also connected to a low voltage terminal (e.g., Vgl).

In some embodiments, as shown in fig. 5d, the third switching sub-circuit 113 includes a second transistor M2 and a third transistor M3.

The gate of the third transistor M3 is electrically connected to the second auxiliary line 132, and the second pole of the third transistor M3 is electrically connected to the pixel electrode 1012.

In this way, each subpixel region 101 on the array substrate 10 corresponds to three transistors, so that the display parameters of the display panel are more uniform.

In addition, as can be seen from the above description, the scan line GL is connected to both the first transistor M1 and the second transistor M2, so that when the scan line GL is fabricated, only the first transistor M1 is connected to the scan line GL, and the gate of the second transistor M2 connected to the scan line GL needs to be increased, which increases the trace area of the scan line GL. In this case, in order to make the overlapping area of the first auxiliary line 131 and the touch electrode Tx and the overlapping area of the scan line GL and the touch electrode Tx uniform, to make the compensation more accurate, the size of the third transistor M3 may be increased or the line width of the first auxiliary line 131 may be increased.

As shown in fig. 6a, in some embodiments of the present application, for one of the first auxiliary line groups 13 corresponding to the ith row of touch electrodes Tx, the first auxiliary lines 131 in the first auxiliary line group 13 are electrically connected to the scan lines GL corresponding to the (i-1) th row of touch electrodes Tx, and k +1 first auxiliary lines 131 in the first auxiliary line group 13 are respectively connected to the pixel circuits 110 in the same row of sub-pixels corresponding to the 1 st to the (k + 1) th scan lines GL corresponding to the ith row of touch electrodes Tx.

For another first auxiliary line group 13 corresponding to the ith row of touch electrodes Tx, k +1 first auxiliary lines 131 in the first auxiliary line group 13 are respectively connected to the pixel circuits 110 in the same row of sub-pixels corresponding to the t-k th to t-th scanning lines GL corresponding to the ith row of touch electrodes Tx.

In this way, in the first auxiliary line group 13 corresponding to the i-th row of touch electrodes Tx, the k +1 first auxiliary lines 131 connected to the k +1 scanning lines GL corresponding to the previous row (i-1 row) of touch electrodes Tx are respectively connected to the pixel circuits 110 of the k +1 rows of sub-pixels connected to the k +1 scanning lines GL corresponding to the i-th row of touch electrodes Tx. In the other first auxiliary line group 13 corresponding to the i-th row of touch electrodes Tx, the first auxiliary lines 131 connected to the k +1 scanning lines GL corresponding to the next row (i +1 row) of touch electrodes Tx are connected to the pixel circuits 110 of the k +1 row of sub-pixels electrically connected to the last k +1 scanning lines GL corresponding to the i-th row of touch electrodes Tx. Therefore, the first auxiliary line 131 is prevented from being long, and the manufacturing process is simple.

In addition, in other embodiments of the present application, as shown in fig. 6b, in the first auxiliary line group 13 corresponding to the i-th row of touch electrodes Tx, the first auxiliary line 131 connected to the k +1 scan lines GL corresponding to the previous row (i-1 row) of touch electrodes Tx is connected to the pixel circuit 110 of the k +1 row of sub-pixels connected to the last k +1 scan lines GL corresponding to the i-th row of touch electrodes Tx. In the other first auxiliary line group 13 corresponding to the i-th row of touch electrodes Tx, the first auxiliary lines 131 connected to the k +1 scanning lines GL corresponding to the next row (i +1 row) of touch electrodes Tx are connected to the pixel circuits 110 of the k +1 rows of sub-pixels electrically connected to the k +1 scanning lines GL corresponding to the i-th row of touch electrodes Tx. Therefore, the wiring design of the array substrate is facilitated.

Alternatively, in other embodiments, in each first auxiliary line group 13 corresponding to the ith row of touch electrodes Tx, k +1 first auxiliary lines 131 may be connected to the pixel circuits 110 of the k +1 rows of sub-pixels connected to any k +1 scanning lines GL corresponding to the ith row of touch electrodes Tx.

For convenience of description, fig. 6a and 6b only show the connection mode of the first auxiliary lines 131 corresponding to the i-th row of touch electrodes Tx. It can be understood that, for any row of touch electrodes Tx, the corresponding first auxiliary lines 131 are connected as described above.

The following description will further illustrate the principle and effect of the array substrate 10 provided by the present application for improving the horizontal stripes of the edges of the touch electrodes Tx by taking the array substrate 10 including 8CLK GOAs as an example.
