In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed in itself. In addition, the examples of various specific processes and materials provided by the present application, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials. In some instances, methods, means, components and circuits well known to those skilled in the art are not described in detail, so as to highlight the subject matter of the present application.

[0025] The present application mainly provides a touch driving circuit, which is applied to a touch display panel, wherein the touch display panel includes a plurality of touch areas arranged in an array, and at least one common electrode line is provided in the touch display panel. The touch driving circuit includes: a touch detection unit, which is used to detect whether the touch display panel is touched, and to generate a current touch signal when the touch display panel is touched; a touch driving unit, which is electrically connected to the touch detection unit, and is used to obtain position information of the touch area corresponding to the touch signal according to the touch signal; a site selection unit, which is electrically connected to the touch driving unit, and is used to receive the position information, and to determine the common electrode line corresponding to the touch signal according to the position information; and a drive adjustment unit, which is electrically connected to the site selection unit, and is used to adjust the corresponding touch driving signal according to the common electrode line.

[0026] Compared with the related art of driving all touch areas in the entire display panel, the embodiment of the present application uses the common electrode line corresponding to the touch signal to adjust the corresponding touch driving signal, which can reduce the number of driven touch areas and further reduce the power consumption of the touch display panel.

[0027] Figure 1 A schematic diagram of a touch driving circuit according to an embodiment of the present application is shown.

[0028] like Figure 1 As shown, the touch driving circuit of the embodiment of the present application can be applied to a touch display panel, the touch display panel includes a plurality of touch areas arranged in an array, at least one common electrode line is provided in the touch display panel, and the touch driving circuit includes: a touch detection unit 11, a touch driving unit 12, a site selection unit 13 and a drive adjustment unit 14. The touch driving unit 12 is electrically connected to the touch detection unit 11, and the site selection unit 13 is electrically connected to the touch driving unit 12 and the drive adjustment unit 14.

[0029] Each of the touch control areas is provided with a touch control electrode corresponding to the touch control area, each column of the touch control areas corresponds to a common electrode line, and each common electrode line is insulated from the corresponding column of the touch control areas. Exemplarily, each of the touch control electrodes may be in the shape of a strip or other shapes. It is understood that the present application does not limit the shape of each of the touch control electrodes.

[0030] Further, the touch detection unit is used to detect whether the touch display panel is touched, and to generate a current touch signal when the touch display panel is touched. The touch detection unit can be electrically connected to each of the touch areas through a corresponding touch line, and each of the touch lines can be a metal wiring. Exemplarily, each of the touch lines can be electrically connected to each of the touch electrodes in the corresponding column of touch areas, so as to detect whether the touch area of ​​the corresponding column is touched.

[0031] It should be noted that the touch display panel of the embodiment of the present application can be a self-capacitive touch display panel or a mutual-capacitive touch display panel, and the present application does not limit the type of touch display panel. For example, the present application takes a self-capacitive touch display panel as an example for description.

[0032] Furthermore, the touch detection unit is electrically connected to each of the touch areas through corresponding touch lines, and the touch detection unit includes a capacitance detection unit and a touch signal generating unit, wherein the capacitance detection unit is used to detect the touch capacitance of each of the multiple touch areas; the touch signal generating unit is electrically connected to the capacitance detection unit, and is used to generate a current touch signal when the touch capacitance changes.

[0033] Taking a self-capacitive touch display panel as an example, each of the touch electrodes can form a corresponding touch capacitor with the ground. When a hand touches the display panel, the hand capacitance will cause the touch capacitor at the corresponding touch position to change. According to the change of the touch capacitor before and after the touch, a corresponding touch signal can be generated to determine the specific position of the touch, such as the row number and column number of the touch electrode or touch area.

[0034] Figure 2 A schematic diagram showing a touch display panel and a touch driving circuit according to an embodiment of the present application is shown.

[0035] like Figure 2 As shown, the touch display panel 20 may include a plurality of touch areas arranged in an array. The touch area 21 may be any touch area. In the embodiment of the present application, starting from the leftmost side, Figure 2 The touch area 21 in the figure is located in the fourth column of touch areas; starting from the top, Figure 2 The touch area 21 in FIG. 1 is located in the first row of touch areas. Therefore, Figure 2 The position of the touch area 21 in can be expressed as touch area (1,4), wherein the first number represents the row number of the touch area, and the second number represents the column number of the touch area. The following expressions used in the embodiments of the present application are similar to this and will not be repeated.

[0036] Further, see Figure 2, the touch display panel may also include a pixel unit array arranged in an array form, and the pixel unit array may be driven by multiple gate signals and multiple data signals so that the touch display panel can display normally. In the embodiment of the present application, one pixel unit may correspond to one touch area. Of course, one touch area may also correspond to multiple pixel units. It can be understood that the present application does not limit the correspondence between pixel units and touch areas.

[0037] Furthermore, the multiple gate signals (also called scanning signals) can be generated by a gate driver, and a thin film transistor can be provided in each of the pixel units. Each gate signal can be electrically connected to the gates of all the thin film transistors in a row of pixel units to control the thin film transistors in the touch area of ​​the corresponding row to input the corresponding data signal into each pixel unit of the corresponding row when it is turned on, so that the corresponding pixel unit lights up and emits light, thereby displaying the display screen.

[0038] Furthermore, the plurality of data signals may be generated by a source driver, and the data lines corresponding to the respective data signals may be electrically connected to the corresponding pixel units so as to write data to the corresponding pixel units. It is understood that there are many ways to arrange the pixel unit array, and the present application does not limit the specific architecture of the pixel unit array.

[0039] See also Figure 2 The touch driving circuit of the embodiment of the present application may include a touch driving signal generating device and a Vcom addressing module. Figure 2 The touch drive signal generating device in the embodiment is the drive adjustment unit, and the Vcom addressing module is the addressing unit. It is worth noting that the touch line 22 can also be a line between the touch area (1, 1) and the touch detection unit. The common electrode line of the embodiment of the present application can be reused as a line between the touch area and the drive adjustment unit, and can also be reused as a line between the touch area and the addressing unit. Reusing the common electrode line can save the number of lines, which is simple and convenient.

[0040] Furthermore, a touch drive unit is electrically connected to the touch detection unit, and is used to obtain the position information of the touch area corresponding to the touch signal according to the touch signal. Exemplarily, the touch signal before the touch may be a square wave signal. After the touch occurs, the signal amplitude at certain positions of the touch signal may change due to the change of the touch capacitance, and the touch drive unit may determine the position information of the touch area corresponding to the touch signal according to the time period in which the changed signal is located. It can be understood that there may be multiple ways to obtain the position information of the touch area corresponding to the touch signal according to the touch signal, and the present application does not limit how to obtain the position information of the touch area.

[0041] Further, the position information of the touch area includes the column number of the touch area corresponding to the touch signal, and the touch driving unit includes: a column number acquisition unit, used to obtain the column number of the touch area corresponding to the touch signal according to the touch signal; a position determination unit, electrically connected to the column number acquisition unit, used to obtain the position information of the touch area corresponding to the touch signal according to the column number of the touch area. In the embodiment of the present application, it can be understood that if each common electrode line and the touch line are arranged horizontally, the row number of the touch area corresponding to the touch signal can also be obtained according to the touch signal. By obtaining the column number of the touch area corresponding to the touch signal, it is not necessary to obtain the row number while obtaining the column number. The embodiment of the present application can reduce the workload in the process of determining the position information of the touch area, thereby reducing the power consumption of the touch area position determination process.

[0042] Furthermore, the address selection unit is electrically connected to each of the touch control areas through corresponding common electrode lines, wherein the common electrode lines are parallel to each other. Figure 2 In the embodiment, each common electrode line is distributed in a river shape. Common electrode line 23, common electrode line 24, common electrode line 25, and common electrode line 26 can be electrically connected to the addressing unit, respectively, and common electrode line 23, common electrode line 24, common electrode line 25, and common electrode line 26 are parallel to each other. It should be noted that each common electrode line can be parallel to each other in the horizontal direction (i.e., horizontal direction) or in the vertical direction (i.e., vertical direction).

[0043] Further, the address selection unit is electrically connected to the touch driving unit, and is used to receive the position information and determine the common electrode line corresponding to the touch signal according to the position information. For example, in 2, if the position information is the touch area in the first column, it means that the current actual touch position is located in the touch area in the first column, and the common electrode line corresponding to the position information is the common electrode line 23.

[0044] Figure 3 A schematic diagram showing a touch capacitor according to an embodiment of the present application is shown.

[0045] like Figure 3 As shown, the touch capacitor of the embodiment of the present application includes a first capacitor, a second capacitor, a third capacitor and a fourth capacitor, wherein the second capacitor includes the capacitance between the common electrode line corresponding to the current touch area and the untouched area; the third capacitor is the capacitance between the current touch area and the untouched area; and the fourth capacitor is the capacitance between the current touch area and the corresponding data line.

[0046] See also Figure 3 , C GV is the first capacitor, C ABS is the second capacitor, CW is the third capacitor, C SV is the fourth capacitor. The gray area is the current touch area (the area corresponding to the touch signal Touch Signal). Gate is the scan line corresponding to the current touch area, Source is the data line corresponding to the current touch area, and VCOM is the touch drive signal on the common electrode line. The scan signal, the data signal, the touch drive signal on the common electrode line, and the touch signal can all be square waves. It should be noted that the untouched area of ​​the embodiment of the present application may be other touch areas in the touch panel except the current touch area. There may be multiple touch areas, which can be pre-set according to actual needs. The touch capacitor may be the total equivalent capacitance of the first capacitor, the second capacitor, the third capacitor, and the fourth capacitor.

[0047] Furthermore, the working time of the touch driving circuit includes a plurality of working cycles, and each of the working cycles includes a display phase and a touch phase.

[0048] The drive adjustment unit further includes a voltage loading unit, the voltage loading unit is electrically connected to each of the common electrode lines, and the voltage loading unit is used to load an initial common voltage to each of the common electrode lines during the display phase. By using the voltage loading unit to preload the initial common voltage during the display phase, the normal power supply of the touch display panel during the display phase can be guaranteed.

[0049] Furthermore, the drive adjustment unit is electrically connected to each of the touch areas through corresponding touch lines, and the drive adjustment unit includes a touch detection unit and a drive adjustment sub-unit, and the touch detection unit is electrically connected to the drive adjustment sub-unit, wherein the touch detection unit is used to detect whether the touch stage has started; the drive adjustment sub-unit is electrically connected to the touch detection unit, and is used to adjust the corresponding touch drive signal according to the common electrode line after detecting that the touch stage has started.

[0050] Specifically, adjusting the corresponding touch drive signal according to the common electrode line may be adjusting the voltage amplitude of the corresponding touch drive signal, or may be adjusting parameters such as frequency and phase. When the touch drive signal is a current signal, parameters such as the amplitude, frequency and phase of the current signal may also be adjusted. The touch drive signal may be used to drive the touch area corresponding to the common electrode line. The embodiment of the present application can drive the touch area corresponding to each common electrode line separately by adjusting the touch drive signal. Compared with the related art in which all touch areas in the entire display panel are driven, the present application can drive part of the touch area of ​​the common electrode line corresponding to the touch area, thereby further saving power consumption.

[0051] Figure 4 A schematic diagram showing a touch driving method according to an embodiment of the present application is shown.

[0052] like Figure 4 As shown, the present application further provides a touch driving method, which is applied to the touch driving circuit, and the touch driving method includes:

[0053] Step S1: Detecting whether the touch display panel is touched, and generating a current touch signal when the touch display panel is touched;

[0054] Further, detecting whether the touch display panel is touched and generating a current touch signal when the touch display panel is touched includes:

[0058] Furthermore, obtaining the position information of the touch area corresponding to the touch signal according to the touch signal includes:

[0060] Step S22: obtaining position information of the touch area corresponding to the touch signal according to the column number of the touch area.

[0061] Step S3: receiving the position information, and determining the common electrode line corresponding to the touch signal according to the position information;
