DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be appreciated that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some but not all structures related to the present application are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present application.

[0034] The terms "first", "second", etc. in this application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0035] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0036] At present, touch technology is mainly divided into On-Cell (external integration) technology and In-Cell (internal integration) technology: Among them, On-Cell refers to the method of embedding the touch screen between the display screen and the polarizer, that is, equipping the display panel with a touch sensor and integrating the touch sensor directly into each pixel of the liquid crystal display panel; this technology requires the touch function to be integrated during the manufacturing process of the display panel. In-Cell refers to embedding the touch panel function into the array substrate, that is, integrating the touch sensor above the display panel, usually between the color filter and the polarizer. In this way, the thickness of the In-Cell panel is greatly reduced due to the lack of a layer of touch screen thickness. This technology is relatively easy to implement because it does not require changing the internal structure of the display panel.

[0037] For the TP (touch) method, the pixel COM electrode (common electrode) is generally used for partitioning. Each sensor line (touch line) can only control one touch block scan. Its driving method is generally Long V or Long H mode, and touch scanning is required at the end of the frame or between frames; the first mode (Long V) is to divide it into a display time period and a touch time period when displaying a frame, that is, the touch time period is placed after the display time period, and the sum of the two time periods is the time of one frame; the other mode (Long H) is to insert the touch time period into the display time period in batches when displaying a frame, that is, under one frame, it will be divided into a cycle of display-touch-display-touch-display from top to bottom.

[0038] For the TP touch method, a common COM electrode partition is generally used, and each sensor line (touch line) can only control one touch block scan. Its driving method is generally Long V or Long H mode, and TP scanning is required at the end of a frame or between frames; therefore, the present application provides a touch driving circuit, an array substrate and a display device, and a method of using a TP-gate line (touch scanning line) to control the opening of a touch block. Only one TP-senser line is required for each column, which greatly saves the space for the touch line. For larger panels, touch block partitions of any size can also be achieved, and touch scanning can be performed at any time, which can achieve more intensive and accurate touch acquisition.

[0039] See also Figure 1a As shown, Figure 1a It is a structural schematic diagram of the first embodiment of the touch driving circuit provided by the present application; AA is a display area; the touch driving circuit 100 includes: a touch electrode 10, a touch line 20, a scan line 30 and a first switch unit 40; specifically, the touch electrode 10 is formed by connecting the common electrodes of a plurality of pixels distributed in an array; a column of touch electrodes 10 corresponds to a touch line 20; a row of pixels corresponds to a scan line 30; each touch electrode 10 corresponds to at least one first switch unit 40, a first end of the first switch unit 40 is connected to the corresponding touch electrode 10, a second end of the first switch unit 40 is connected to the corresponding touch line 20, and a control end of the first switch unit 40 is connected to a scan line 30 corresponding to the next row of touch electrodes 10 according to the scan order of the scan lines 30.

[0040] Optionally, in one embodiment, if Figure 1a As shown, the control end of the first switch unit 40 is connected to the first scan line 30 of the multiple scan lines 30 corresponding to the next row of touch electrodes 10 according to the scan order of the scan lines 30. It can be understood that in the above embodiment, the control end of the first switch unit 40 is connected to a scan line 30 corresponding to the next row of touch electrodes 10 according to the scan order of the scan lines 30, wherein the control end of the first switch unit 40 is connected to any scan line 30 corresponding to the next row of touch electrodes 10 according to the scan order of the scan lines 30, and in this embodiment, the control end of the first switch unit 40 is connected to the first scan line 30 of the multiple scan lines 30 corresponding to the next row of touch electrodes 10. For example, the orthographic projection of a touch electrode 10 on the array substrate 200 overlaps with the orthographic projection of the scan lines 30 of the G(1) to G(n) rows, and the first switch unit 40 connected to the touch electrode 10 is connected to the scan line 30 of the G(n+1) row.

[0041] Understandable, such as Figure 1aAs shown, the area where multiple pixels are located on the display panel is divided into multiple touch areas, each touch area corresponds to a touch block (i.e., touch electrode 10), wherein the common electrodes (COM electrodes) in each touch block are connected together, and the common electrodes (COM electrodes) between the multiple touch blocks are divided to form individual touch blocks. Each individual touch block is connected to the touch line 20 of each column by the first switch unit 40, and the gate signal (gate signal) of the next row is used as the control signal of the first switch unit 40 to control the conduction of the touch block and the touch line 20 of the previous row, and a dummy gate is set in the last row as a touch start signal.

[0042] Optionally, in one embodiment, if Figure 1b As shown, Figure 1b It is a structural schematic diagram of the second embodiment of the touch driving circuit provided in the present application; the first switch unit 40 includes a first transistor Q1, and the first transistor Q1 is an NMOS transistor; wherein the first end of the first transistor Q1 is connected to the corresponding touch electrode 10, the second end of the first transistor Q1 is connected to a corresponding touch line 20, and the control end of the first transistor Q1 is connected to a scan line 30 corresponding to the next row of touch electrodes 10 according to the scan order of the scan lines 30.

[0043] Further, such as Figure 2 and Figure 3 As shown, Figure 2 is an equivalent circuit diagram of an embodiment of a single pixel in a touch driving circuit provided by the present application; Figure 3 It is a cross-sectional view of an embodiment of a single pixel in a touch driving circuit provided by the present application; the CF (Color Filter) is a key component of a liquid crystal display (LCD) and is used to provide color for each pixel. TFT (Thin-Film Transistor) is a semiconductor device widely used in liquid crystal displays (LCDs). TFT technology is the key to enabling LCDs to accurately control the brightness of each pixel. ITO refers to Indium Tin Oxide, a transparent conductive material widely used in touch screen technology.

[0044] Among them, the COM electrode is shared by the COM ITO in the touch block. During the charging process of the pixel, the downstream Gate line is in a low level state. At this time, the touch block and the touch line 20 are not connected, and the pixel electrode is charged normally. After the pixel charging is completed, the TFT switch of the pixel is disconnected. Due to the charge conservation, the pixel voltage will not be affected. During the scanning process, the Gate line of the next row is in a high level state, the touch switch is turned on, and the touch scanning is performed.

[0045] Optionally, in one embodiment, if Figure 4 As shown, Figure 4 is an equivalent circuit diagram of a single pixel in the second embodiment of the touch driving circuit provided by the present application; each touch electrode 10 corresponds to a plurality of first switch units 40, and the control ends of the plurality of first switch units 40 are respectively connected to a plurality of scan lines 30 corresponding to the next row of touch electrodes 10 according to the scan sequence of the scan lines 30. Similarly, in Figure 4 In the example, multiple rows of gates are used to control the on and off of the touch switches, and the gate signals of rows G(n+1) to G(2n) are used to control the opening of the touch blocks to extend the scanning time. The last row can be opened by setting the same number of dummy gates.

[0046] Optionally, in one embodiment, if Figure 4 As shown, the number of the first switch units 40 corresponding to each touch electrode 10 is the same as the number of the scan lines 30 corresponding to the next row of touch electrodes 10 .

[0047] Optionally, in one embodiment, see Figure 5 As shown, Figure 5 is a schematic structural diagram of a third embodiment of a touch driving circuit provided in the present application; Figure 5 In the embodiment, the touch driving circuit 100 also includes: a second switch unit 50, each touch electrode 10 corresponds to at least one second switch unit 50, a first end of the second switch unit 50 is connected to the corresponding touch electrode 10, a second end of the second switch unit 50 is configured to input a common signal, and a control end of the second switch unit 50 is connected to a scan line 30 corresponding to the next row of touch electrodes 10 according to the scan order of the scan line 30.

[0048] It can be understood that by setting the second switch unit 50 to access a COM signal to avoid the touch block being in a floating state after the TP touch is turned off, the COM voltage may also be affected by feedtrough, etc. Feedtrough refers to the phenomenon of signal transmission caused by electromagnetic coupling or capacitive coupling between different signal lines in an electronic circuit, which is an undesirable phenomenon because it may interfere with other signals in the circuit.

[0049] Optionally, in one embodiment, if Figure 6 As shown, Figure 6It is a structural schematic diagram of the fourth embodiment of the touch driving circuit provided in the present application; the second switch unit 50 includes a second transistor Q2, and the second transistor Q2 is a PMOS transistor; wherein the first end of the second transistor Q2 is connected to the corresponding touch electrode 10, the second end of the second transistor Q2 is configured to input a common signal, and the control end of the second transistor Q2 is connected to a scan line 30 corresponding to the next row of touch electrodes 10 according to the scan order of the scan lines 30.

[0050] It can be understood that NMOS (N-type metal oxide semiconductor) and PMOS (P-type metal oxide semiconductor) are two basic types of transistors in NMOS transistors and PMOS transistors; NMOS transistors are usually turned on when a certain threshold voltage higher than the source is applied to the gate (Gate). When the gate voltage is lower than the threshold voltage, the NMOS transistor is in a cut-off state, and electrons cannot flow from the source to the drain (Drain). When the gate voltage is higher than the threshold voltage, the NMOS transistor is turned on, forming a conductive channel, allowing electrons to flow from the source to the drain. PMOS transistors are usually turned on when a certain threshold voltage lower than the source is applied to the gate. When the gate voltage is higher than the source voltage, the PMOS transistor is in a cut-off state, and holes cannot flow from the source to the drain. When the gate voltage is lower than the source voltage, the PMOS transistor is turned on, forming a conductive channel, allowing holes to flow from the source to the drain. That is, the conduction modes of NMOS transistors and PMOS transistors are opposite, for example, the PMOS transistor is "low-level conduction", that is, it is turned on when the gate voltage is lower than the source voltage. NMOS transistors are "high level turned on", that is, turned on when the gate voltage is higher than the source voltage. In one embodiment, the control turn-on of the first switch unit 40 is opposite to that of the second switch unit 50, that is, when the first switch unit 40 is high level turned on, the second switch unit 50 is high level turned off, for example, the first switch unit 40 is an NMOS transistor, and the second switch unit 50 is a PMOS transistor.

[0051] Optionally, in one embodiment, if Figure 7 As shown, Figure 7: is a structural schematic diagram of the fifth embodiment of the touch driving circuit provided by the present application; in this embodiment, the second switch unit 50 includes: a third transistor Q3, a fourth transistor Q4 and a fifth transistor Q5; wherein, the first end of the third transistor Q3 is connected to the corresponding touch electrode 10, and the second end of the third transistor Q3 is configured to input a common signal; the first end and the control end of the fourth transistor Q4 are configured to input a high-level signal, and the second end of the fourth transistor Q4 is connected to the control end of the third transistor Q3; the first end of the fifth transistor Q5 is configured to input a low-level signal, and the second end of the fifth transistor Q5 is connected to the control end of the third transistor Q3, and the control end of the fifth transistor Q5 is connected to a scan line 30 corresponding to the next row of touch electrodes 10 according to the scan order of the scan lines 30; wherein the third transistor Q3, the fourth transistor Q4 and the fifth transistor Q5 are NMOS transistors.

[0052] It is understandable that if we consider that the touch block is in a floating state after the TP touch is turned off, the COM voltage may also be affected by the feedthru, etc. On this basis, we can add a set of inverting devices and connect the COM signal (common signal), such as Figure 7 As shown, when the corresponding touch switch (first switch unit 40) is closed, the COM switch (i.e., the third transistor Q3) is turned on by the VDD signal (high level signal), and the touch block is connected to the COM signal to stabilize the COM voltage. When the touch switch is turned on, VGL (low level signal) pulls down the gate of the COM switch (i.e., the third transistor Q3), and the third transistor Q3 is disconnected at this time, that is, the touch block is not connected to the COM signal, so as not to affect the touch scan. Wherein VGL needs to ensure that the voltage is low enough or the channel width-to-length ratio of the fourth transistor Q4 is designed to be much smaller than the fifth transistor Q5, so as to ensure that the gate node of the third transistor Q3 can be pulled down to the point where the third transistor Q3 is completely turned off.

[0053] In another optional embodiment, Figure 8 and Fig. 9 As shown, Figure 8 is a structural schematic diagram of a sixth embodiment of a touch driving circuit provided by the present application; Fig. 9 yes Figure 8 The corresponding waveform diagram; Figure 8 As shown, a set of separate TP-gate signals (touch scanning signals) are used for driving, and the waveform thereof corresponds to the following Fig. 9As shown, when the pixels in the corresponding touch block are charged, the TP-gate of the row where it is located is closed and the touch blocks in other rows are opened. At this time, the touch blocks in other rows can be scanned normally. The touch scanning frequency can be controlled by the IC, and more scans can be performed without affecting the charging time. Compared with the traditional Long H or Long V mode that requires scanning when charging is paused, it is more flexible.

[0054] To solve the above problems, the present application also provides an array substrate 200. Fig.10 As shown, Fig.10 It is a structural schematic diagram of an embodiment of an array substrate provided in the present application; the array substrate 200 includes: scan lines 30, data lines 60 and a touch drive circuit 100; wherein the scan lines 30 and the data lines 60 are interlaced with each other to form a plurality of pixel areas distributed in an array; the touch drive circuit 100, the touch drive circuit 100 is the touch drive circuit 100 described in any one of the above embodiments.

[0055] To solve the above problems, the present application also provides a display device 300, see Fig.11 As shown, Fig.11 It is a structural schematic diagram of an embodiment of a display device provided in the present application; the display device 300 includes: an array substrate 200, a color film substrate 310, and a liquid crystal layer 320 arranged between the array substrate 200 and the color film substrate 310, and the array substrate 200 is the array substrate 200 described in any one of the above embodiments.

[0056] The present application provides a touch driving circuit 100, which includes: a touch electrode 10, a touch line 20, a scan line 30 and a first switch unit 40; specifically, the touch electrode 10 is formed by connecting the common electrodes of a plurality of pixels distributed in an array; a column of touch electrodes 10 corresponds to a touch line 20; a row of pixels corresponds to a scan line 30; each touch electrode 10 corresponds to at least one first switch unit 40, a first end of the first switch unit 40 is connected to the corresponding touch electrode 10, a second end of the first switch unit 40 is connected to the corresponding touch line 20, and a control end of the first switch unit 40 is connected to a scan line 30 corresponding to the next row of touch electrodes 10 according to the scanning order of the scan lines 30.

[0057] In the above manner, a touch line 20 is used to control a column of touch blocks, saving the use space of the touch line 20. For a large-size display panel, the size of the touch area can be arbitrarily partitioned and touch scanning can be performed at any time, thereby achieving dense and accurate touch acquisition.
