As an example, the driving unit in the composite driving circuit 13 supplies a gate driving signal to G1, and the transistor connected to G1 is turned on. At this time, in the array substrate, a row of sub-pixels corresponding to G1 is electrically connected to the data line and receives the data signal. In addition, the driving unit in the composite driving circuit 13 can also be used as a touch driving circuit.

Also, the position of the driving unit can be set according to actual needs. Such as: and the array substrate is positioned in the lower side frame or the upper side frame of the array substrate.

In this embodiment, the composite driving unit is disposed in at least one side frame extending along the first direction of the array substrate, and the composite driving unit includes at least one driving unit. Meanwhile, the driving unit can provide a grid driving signal in a display stage and can provide a touch driving signal in a touch stage.

Please refer to fig. 2, which is a schematic structural diagram illustrating an embodiment of a driving unit in a composite driving circuit in an array substrate according to the present disclosure.

In this embodiment, the driving unit includes a gate driving unit 201 and a touch driving unit 202. In the same driving unit, R-level gate driving units 201 are arranged between every two adjacent touch driving units 202, wherein R is not less than 0, and R is an integer. As shown in fig. 2, the gate driving unit 201 includes VSR1, VSR2, VSR3, VSR4 … VSRa. The touch driving unit 202 includes TXVSR1, TXVSR2 … TXVSRb. Wherein a and b are positive integers. And two stages of gate driving units 201 are spaced between two adjacent stages of touch driving units 202. For example: the TXVSR1 is spaced from the TXVSR2 by VSR3 and VSR 4.

In this embodiment, the driving unit may be a shift register group. The grid driving unit in the shift register group is a grid driving shift register unit. The touch driving unit in the shift register group is a touch driving shift register unit. In the touch control stage, the grid in the shift register group drives the shift register unit to be in a floating state; in the display stage, the touch-control driving shift register unit in the shift register group is in a floating state. Or when the first touch electrode is reused as a common electrode, the first touch electrode receives a touch driving signal in a touch stage; in the display stage, the first touch electrode receives a common voltage signal. The touch driving signal and the common voltage signal can be provided by the touch driving shift register unit.

In order to implement the array substrate of the present application in the prior art, i.e., utilize the I/O ports of the existing integrated circuit IC without additionally expanding and increasing the number of the I/O ports, in the present embodiment, each stage of the gate driving unit drives at least two scan lines, and/or each stage of the touch driving unit drives at least one first touch electrode. As shown in fig. 2, VSR1 drives scan line G1 and scan line G2; VSR2 drives scan line G3 and scan line G4; VSR3 drives scan line G5 and scan line G6; VSR4 drives scan line G7 and scan line G8; VSRa drives the scan line GM-1 and the scan line GM. The TXVSR1 and the TXVSR2 … TXVSRb can drive a first touch electrode through the touch signal line 205 respectively.

In this embodiment, the driving unit further includes a gate units 203. And each of the gate units 203 may correspond to at least two scan lines, and each of the gate units 203 corresponds to one stage of the gate driving unit 201. And the gate unit 203 transmits the gate driving signal output from the gate driving unit 201 to one of the scan lines corresponding to the gate unit 203 in response to the control signal. As can be seen from fig. 2, the gate unit 203 includes X1, X2, X3, and X4 … Xa. The VSR1 is connected to the scan line G1 and the scan line G2 via X1. The X1 is connected to the control signal line 204 and transmits a gate driving signal output from the VSR1 to the scan line G1 or the scan line G2 in response to a control signal output from the control signal line 204. Similarly, VSR2 is connected to scan line G3 and scan line G4 through X2. The VSR3 is connected to the scan line G5 and the scan line G6 via X3. The VSR4 is connected to the scan line G7 and the scan line G8 via X4. VSRa is connected to scan line GM-1 and scan line GM through Xa.

In some alternative implementations of the present embodiment, each gating cell may be connected to three or more scan lines. Meanwhile, each touch driving unit may simultaneously drive or time-divisionally drive two or more first touch electrodes. It is understood that when the same touch driving unit is used for driving two or more first touch electrodes in a time-sharing manner, the gating unit as described above may also be provided. The gating unit responds to the control signal and transmits the touch driving signal output by the touch driving unit to a first touch electrode.

Therefore, the number of occupied I/O ports can be reduced, the number of grid driving units and/or touch driving units can be reduced, the production process is simplified, the production cost is reduced, and the width of a frame area is further narrowed. When each touch driving unit drives two or more first touch electrodes simultaneously, the working efficiency of the touch stage can be improved.

Optionally, according to different production processes, the position between the touch driving unit and the gate driving unit may be arbitrarily set, and the present application is not limited thereto.

With reference to fig. 3, the composite driving circuit in the array substrate of the present application may include at least two driving units, and the at least two driving units may be respectively located in two side frames extending along the first direction of the array substrate. The following description will be made in a case where the composite drive circuit includes two drive units, and as shown in fig. 3, the composite drive circuit includes a first drive unit 31 and a second drive unit 32. And the first driving unit 31 and the second driving unit 32 are respectively located in a lower side frame and an upper side frame of the array substrate extending in the first direction. The first touch electrode comprises TX1, TX2 and TX3 … TXN.

In this embodiment, the array substrate may include at least two touch electrode sets and/or at least two scan line sets. Each touch electrode group and each scanning line group correspond to one driving unit. When the array substrate includes two touch electrode sets and/or two scan line sets, the array substrate may include a first touch electrode set and a second touch electrode set, and/or a first scan line set and a second scan line set.

As shown in fig. 3, the array substrate in this embodiment includes a first scan line group and a second scan line group. Wherein, the first scan line group includes even number of scan lines, such as: g2, G4 and G6; the second scan line group includes odd scan lines, such as: g1, G3 and G5. The first driving unit 31 may drive the first scan line group, and the second driving unit 32 may drive the second scan line group.

Meanwhile, the first driving unit 31 and the second driving unit 32 are connected to each first touch electrode through a touch signal line. The TX1 may receive touch driving signals of the first driving unit 31 and the second driving unit 32 at two ends extending along the first direction, respectively. In the touch stage, the same first touch electrode can receive a touch driving signal from both ends. Therefore, the reduction of touch detection precision caused by different touch driving signal intensities at two ends can be effectively avoided.

Compared with the embodiment shown in fig. 1, the composite driving circuit in the present embodiment includes two driving units, which can respectively drive a part of the scan lines, thereby realizing independent control of each scan line group. Meanwhile, the two driving units are respectively positioned at the upper side and the lower side of the array substrate, so that the width of a frame at one side is reduced.

With continued reference to fig. 4, as in the embodiment shown in fig. 3, the composite driving circuit in the array substrate of the present application also includes a first driving unit 41 and a second driving unit 42. And the first driving unit 41 and the second driving unit 42 are respectively located in the upper side frame and the lower side frame of the array substrate. The first touch electrode also includes TX1, TX2, TX3 … TXi, TXi +1 … TXN-1, TXN. Wherein i is a positive integer, and i is more than or equal to 1 and less than or equal to N-1.

Unlike the embodiment shown in fig. 3, the array substrate in this embodiment includes a first touch electrode set and a second touch electrode set. The first touch electrode group comprises 1 st to ith first touch electrodes, and the second touch electrode group comprises i +1 th to nth first touch electrodes. As shown in fig. 4, the first touch electrode group includes TX1 to TXi, and the second touch electrode group includes TXi +1 to TXN. In the touch stage, the first driving unit 41 is used for driving the first touch electrode group, and the second driving unit 42 is used for driving the second touch electrode group. Therefore, independent driving control of each touch electrode group can be realized.

The array substrate in this embodiment also includes a first scan line group and a second scan line group. Two adjacent scan lines may be regarded as one scan line unit. The first scanning line group comprises odd scanning line units; the second scan line group includes an even number of scan line units. As can be seen from fig. 4, G1 and G2 are first scan line units; g3 and G4 are second scan line units; g5 and G6 are third scan line units; g7 and G8 are fourth scan line units, and so on. Accordingly, the first scan line group includes G1, G2, G5, and G6; the second scan line group includes G3, G4, G7, and G8. In the display phase, the first driving unit 41 is used for driving each scan line in the first scan line group, and the second driving unit 42 is used for driving each scan line in the second scan line group. Compared with the embodiment shown in fig. 3, the total length of the data transmission signal lines connecting each driving unit and each corresponding scanning line group is shorter in the embodiment, so that the material resources for production are saved. For example: the total length of the data transmission signal lines connecting the first driving unit 41 and the G1 and G2 in this embodiment is smaller than the total length of the data transmission signal lines connecting the second driving unit 32 and the G1 and G3 in the embodiment shown in fig. 3.

In some optional implementations of this embodiment, the positions of the first driving unit and the second driving unit on the array substrate may be interchanged. The first driving unit may be further configured to drive the first touch electrode group and the second scan line group, or the second touch electrode group and the first scan line group, or the second touch electrode group and the second scan line group. And the second driving unit may be used to drive the corresponding other touch electrode groups and scan line groups.

For example, the first touch electrode group may also include TXi +1 to TXN, and the second touch electrode group includes TX1 to TXi. Similarly, the first scan line group may include even scan line units, and the second scan line group includes odd scan line units.

As shown in fig. 5, the composite drive circuit in the present embodiment also includes a first drive unit 51 and a second drive unit 52, as in the embodiment shown in fig. 4. The first and

second driving units

51 and 52 are also located in the upper and lower borders of the array substrate, respectively. And the first driving unit 51 is used for driving the first touch electrode group and the first scan line group. The second driving unit 52 is used for driving the second touch electrode group and the second scan line group.

However, unlike the embodiment shown in fig. 4, the first touch electrode group in this embodiment includes odd-numbered rows of first touch electrodes, such as: TX1, TX3 … TXN. The second touch electrode group includes even number of rows of the first touch electrodes, such as: TX2, TX4 …. Therefore, the coupling condition between two adjacent first touch electrodes can be reduced. For example: in the touch stage, when the first driving unit 51 drives TX1 and TX3 at the same time, since TX2 is spaced between TX1 and TX3, the coupling capacitance between TX1 and TX3 can be effectively reduced. When the first driving unit 51 drives TX1 and the second driving unit 52 also drives TX2, the transmission directions of the touch driving signals of the two are opposite, so that the coupling capacitance between TX1 and TX2 can be reduced to some extent.

In this embodiment, the first scan line group includes scan lines 1 to jth, such as: g1 and G2 … Gj. The second scan line group includes the j +1 th to Mth scan lines, such as: gj +1, … GM-1, GM. Wherein j is a positive integer, and j is more than or equal to 1 and less than or equal to M-1. Or the first scanning line group comprises the scanning lines positioned on the upper half part of the array substrate, and the second scanning line group comprises the scanning lines positioned on the lower half part of the array substrate. Compared with the embodiment shown in fig. 4, the total length of the data transmission signal lines connecting the driving units and the scanning line groups can be further reduced, the production cost can be reduced, and the production process can be simplified. Meanwhile, the extension directions of the data transmission signal line and the data line are the same, so that the length of the data transmission signal line is reduced, and the reduction of the coupling capacitance between the data transmission signal line and the data line is facilitated.

The touch electrode group and the scan line group respectively driven by the first driving unit and the second driving unit are not limited. The first touch electrode group and the second touch electrode group respectively include the first touch electrode, but are not limited thereto. The scanning lines included in each of the first scanning line group and the second scanning line group are also not limited. Any number of driving units, touch electrode groups and scanning line groups can be arranged according to actual needs.

Further refer to fig. 6, which is a schematic structural diagram of an embodiment of a display panel provided in the present application. As shown in fig. 6, the display panel of the present application includes the array substrate in the above embodiments. The array substrate is formed with first touch electrodes 601 extending along a first direction and arranged along a second direction, and scan lines 603 extending along the second direction and arranged along the first direction. The first touch electrode 601 may be divided into a first touch electrode group and a second touch electrode group. And the scan lines 603 may be divided into a first scan line group and a second scan line group. The first driving unit 607 and the second driving unit 608 respectively located in the two side frames of the array substrate extending along the first direction are composite driving circuits. In the display stage, the driving unit in the composite driving circuit is used for providing a grid driving signal for each scanning line group; in the touch stage, the driving unit in the composite driving circuit is used for providing a touch driving signal to each touch electrode group. Reference is made in particular to the embodiment shown in fig. 5.

In this embodiment, the display panel further includes a color filter substrate disposed opposite to the array substrate. A second touch electrode 602 is formed on a side of the color filter substrate away from the array substrate. The second touch electrodes 602 extend along the second direction and are arranged along the first direction. That is, the extending direction of the first touch electrode 601 intersects the extending direction of the second touch electrode 602. In addition, the second touch electrode 602 may be a stripe electrode or a grid electrode. Also made of an electrically conductive material, which may be a metal electrode, for example. As can be seen from fig. 6, the second touch electrode 602 is electrically connected to a flexible circuit board (FPC)606 through a touch signal line. The FPC606 is electrically connected to the integrated circuit 604 through the main flexible circuit board 605.

In this embodiment, the first touch electrode 601 can be a touch emitting electrode, and the second touch electrode 602 is a touch sensing electrode. In the touch stage, the integrated circuit 604 sends a touch driving signal to the first touch electrode 601 in each touch electrode group through the composite driving circuit. Meanwhile, the integrated circuit 604 receives the touch sensing signal returned by the second touch electrode 602 through the main flexible circuit board 605. If the returned touch sensing signal is detected to be inconsistent with the touch driving signal, it can be determined that touch occurs at the overlapping position of the corresponding touch transmitting electrode and the touch sensing electrode.

In this embodiment, the display panel may further be provided with a plurality of data lines (not shown in the figure). The data line extends along a first direction and is used for providing data signals to the pixel electrode in the display area. During the display phase, the integrated circuit 604 sends gate drive signals to each scan line group through the composite drive circuit. The pixel electrode receives a data signal transmitted by the data line. At this time, the first touch electrode 601 may be multiplexed as a common electrode and receive a common voltage signal. At this time, the liquid crystal in the display panel is rotated by the electric field formed between the common electrode and the pixel electrode, so that the polarization direction of the outgoing light is rotated. The intensity of the emergent light is controlled by the polaroid, so that the display of different brightness of each sub-pixel in the picture is realized. It should be noted that the common voltage signal may be sent by the integrated circuit 604, may be sent by the composite driving circuit, and may also be sent by the integrated circuit 604 controlling other circuits or units.

Optionally, the first touch electrode may also be a touch sensing electrode, and the second touch electrode may also be a touch emitting electrode.

It is understood that the display panel in this embodiment may further include some well-known structures, such as a liquid crystal layer disposed between the color filter substrate and the array substrate, spacers for supporting the liquid crystal layer, a protective glass, and a backlight source. Such well-known structures are not shown in fig. 6 in order to avoid unnecessarily obscuring the present application.

As shown in fig. 7, the present application also provides a display device. The display device includes the display panel described in the embodiment of fig. 6. The display device may be various display devices, for example: mobile phones, tablet computers, smart watches, vehicle-mounted display terminals, and the like. According to the display device, the composite driving circuit (the composite driving circuit comprises at least one driving unit) is arranged in at least one side frame of the array substrate extending along the first direction, so that a grid driving signal can be provided for each scanning line in the display stage, the occupation of the space on the left side and the right side of the array substrate is effectively avoided, and the design of narrow frames on the left side and the right side (as shown in 72 in the figure) is facilitated; meanwhile, the composite driving circuit (driving unit) is also used as a touch driving circuit, and a touch driving signal can be provided for each first touch electrode in a touch stage, so that the occupied area of the composite driving circuit is reduced, and the narrow frame design of the side surface (shown as 71 in the figure) where the composite driving circuit is located is facilitated.
