Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the keys in the embodiments can be combined with each other without conflict.
Referring to fig. 2, a schematic structural diagram of a touch device 100 provided in the present application is shown, as shown in fig. 2, the touch device 100 may include a touch panel 110 and a control circuit 130.
The control circuit 130 may include a channel selection unit 150 and a control chip 170. The touch panel 110 may include a plurality of touch sensing columns 111, and each touch sensing column 111 may include a plurality of touch sensing elements 113. The channel selection unit 150 may include a plurality of channel selectors 151.
The touch sensing columns 111 correspond to the channel selectors 151 one by one, and each channel selector 151 is connected to each touch sensing element 113 of the corresponding touch sensing column 111. The control chip 170 is connected to each channel selector 151 in the channel selection unit 150. The channel selection unit 150 is disposed outside the chip of the control chip 170.
For example, as shown in fig. 2, each touch sensing column 111 may include 4 touch sensing elements 113, including a first touch sensing element, a second touch sensing element, a third touch sensing element, and a fourth touch sensing element. Each channel selector 151 is electrically connected to the 4 touch sensing elements 113 of the corresponding touch sensing row 111.
It should be noted that the present application does not limit the composition of the touch sensing elements 113 in the touch sensing columns 111, and the touch sensing columns 111 should be understood in a broad sense, and each touch sensing column 111 may be composed of vertical touch sensing elements 113 as shown in fig. 2, or may be composed of horizontally disposed touch sensing elements 113.
In operation, the control chip 170 may control each channel selector 151 to select a target touch sensing element from the corresponding touch sensing row 111 to be conducted with the control chip 170.
After the target touch sensing element is conducted with the control chip 170, the control chip 170 may load a touch driving signal to the target touch sensing element, so that the target touch sensing element is in a touch state. The target touch sensing element in the touch state can respond to the touch operation of the user to generate a touch electric signal. The control chip 170 obtains the touch electrical signal and analyzes the touch electrical signal to obtain the touch operation information of the user.
It should be noted that the target touch sensing device refers to the touch sensing device 113 that is about to be/is in a touch state, and the target touch sensing device is not limited to the touch sensing device 113.
Based on the above design, the control chip 170 may select the target touch sensing element through the channel selector 151, and enable the target touch sensing element to respond to the touch electrical signal obtained by the user touch operation, and then obtain the touch electrical signal of the target touch sensing element, so as to obtain the touch information of the user, therefore, the control chip 170 does not need to be directly electrically connected to each touch sensing element 113, the number of interfaces between the touch device 100 and the control chip 170 is reduced, the size of the control chip 170 is reduced, meanwhile, the lead circuit between the control chip 170 and the touch sensing element 113 is simplified, and the integration level of the touch device 100 is improved.
In addition, since the lead circuits in the touch display device integrated with the touch apparatus 100 are often arranged along the frame of the touch display device, the size of the frame of the touch display device can be reduced after the lead circuits between the control chip 170 and the touch sensing element 113 are simplified, thereby increasing the screen occupation ratio of the display device.
As an embodiment, with continued reference to fig. 2, the control chip 170 may include a channel selection terminal, and the channel selector 151 may include an input terminal, an output terminal, and a control terminal.
The input end of the channel selector 151 is connected to each touch sensing element 113 of the corresponding touch sensing row 111, the output end is connected to the driving sensing end of the control chip 170, and the control end is used for obtaining a touch channel selection signal.
The channel selector 151 is configured to select a target touch sensing element from the corresponding touch sensing row 111 according to a touch channel selection signal, and connect an input end connected to the target touch sensing element to an output end of the channel selector 151, so that the target touch sensing element is connected to a driving sensing end of the control chip 170.
In operation, to obtain the touch electrical signal of each touch sensing element 113, the channel selection signal may be a time-varying signal, so as to control the channel selector 151 to sequentially select the touch sensing elements 113 to connect with the control chip 170.
For example, the input terminals of the channel selector 151 may include a first input terminal connected to a first touch sensing element, a second input terminal connected to a second touch sensing element, a third input terminal connected to a third touch sensing element, and a fourth input terminal connected to a fourth touch sensing element.
Alternatively, the touch channel selection signal may be a two-bit binary digital signal. Please refer to the timing state of each pin of the channel selector 151 shown in fig. 3, wherein the timing state diagram of each pin includes the level state of the control terminal and the conduction state of the input terminal and the output terminal. The level state of the control terminal is the level state of the touch channel selection signal input to the control terminal.
For example, the process of the channel selector 151 responding to the touch channel selection signal may be divided into four stages:
in the first stage, the touch channel selection signal is "00". At this time, the first touch sensing element of each touch sensing row 111 is a target touch sensing element, the first input end and the output end of each channel selector 151 are conducted, that is, the conduction state of the input end and the output end is "1000", and the control chip 170 is connected to each first touch sensing element.
In the second stage, the touch channel selection signal is "01". At this time, the second touch sensing element of each touch sensing row 111 is a target touch sensing element, the second input end and the output end of each channel selector 151 are conducted, that is, the conduction state of the input end and the output end is "0100", and the control chip 170 is connected to each second touch sensing element.
In the third stage, the touch channel selection signal is "10". At this time, the third touch sensing element of each touch sensing row 111 is a target touch sensing element, the third input end and the output end of each channel selector 151 are conducted, that is, the conduction state of the input end and the output end is "0010", and the control chip 170 is connected to each third touch sensing element.
In the fourth stage, the touch channel selection signal is "11". At this time, the fourth touch sensing element of each touch sensing row 111 is the target touch sensing element, the fourth input end and the output end of each channel selector 151 are conducted, that is, the conduction state between the input end and the output end is "0001", and the control chip 170 is connected to each fourth touch sensing element.
Based on the above design, the control chip 170 can control the touch channel selection signal to change with the time sequence, so as to scan each channel selection unit 150, reduce the number of touch electrical signals to be processed at each stage, and reduce the computation amount.
It should be noted that the same ports in the control terminals of the respective channel selectors 151 may be connected in series, and the channel selection signals may be obtained simultaneously.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a channel selector 151 according to the present application. As shown in fig. 4, the channel selector 151 may include a plurality of field effect transistors 153.
Wherein, the input terminal of the channel selector 151 is composed of the sources of the respective field effect transistors 153 connected to each other; the output terminal of the channel selector 151 is composed of the drain of each field effect transistor 153, and the control terminal of the channel selector 151 is composed of the gate of each field effect transistor 153.
It should be noted that, in operation, the source and drain of the field effect transistor 153 may be interchanged. The input terminal of the channel selector 151 is composed of the drains of the respective field effect transistors 153 connected to each other; the output terminal of the channel selector 151 is composed of the source of each field effect transistor 153.
In operation, the touch channel selection signal may be a turn-on voltage electrical signal, for example, when the touch channel selection signal is "1000", the first field effect transistor corresponding to the first output terminal is turned on, and the first touch sensing element is a target touch sensing element.
Based on the above design, the control flow of the field effect transistor 153 can be reduced, the integration effect of the field effect transistor 153 can be improved, and the process difficulty in actual production can be reduced.
As an embodiment, the control chip 170 may directly control the control terminal of the channel selector 151.
Specifically, the control chip 170 may further include a channel selection terminal, and the channel selection terminal is connected to a control terminal of the channel selector 151.
In operation, the control chip 170 may directly generate the channel selection signal and transmit the channel selection signal to the channel selector 151 through the channel selection terminal.
As another embodiment, the control chip 170 may control the control terminal of the channel selector 151 through the intermediate circuit 190.
For example, referring to fig. 5, the control circuit 130 may further include an intermediate circuit 190, and the intermediate circuit 190 is respectively connected to the control terminal of the channel selector 151 and the control chip 170.
The intermediate circuit 190 is configured to generate a channel selection signal according to an operating signal of the control chip 170, and send the channel selection signal to the channel selector 151.
In operation, the intermediate circuit 190 may be a Panel Gate Driver on Array (Panel Gate Driver on Array) circuit, and the operating signal of the control chip 170 may be a clock signal provided by the control chip 170. The Panel GOA circuit may refer to a gate driving integrated circuit integrated on the touch Panel 110 and/or the display Panel through a thin film transistor.
As an embodiment, the channel selector 151 may include a data selector integrated by a thin film transistor.
It should be noted that the channel selector 151 needs to be understood in a broad sense, and the channel selector 151 only needs to implement the above functions, and cannot be limited to a data selector (MUX) in a narrow sense, and the data selector is only one embodiment of the channel selector 151 in the present application.
Optionally, the control chip 170 may further include a signal processing circuit connected to the driving sensing terminal, where the signal processing circuit is configured to perform capacitance-to-voltage conversion and digital-to-digital conversion on the touch electrical signal sensed by the driving sensing terminal to obtain touch information sensed by the target touch sensing element.

The color filter substrate is arranged opposite to the display panel. The pixel array is integrated on the display panel. The liquid crystal layer is arranged between the display panel and the color filter substrate.
During displaying, the control chip 170 is connected to the pixel array, and is configured to control an electric field strength of an electric field of the pixel array by applying a display image signal to the pixel array, drive liquid crystal molecules in the liquid crystal layer to rotate, and change a light transmittance of the liquid crystal layer, so that the internal light source sequentially passes through the liquid crystal layer and the color filter substrate to form an image to be displayed.
Alternatively, to improve the integration of the touch device 100, the touch panel 110 may be integrated on the display panel to form a touch display panel. At this time, the display function and the touch function of the touch device 100 are implemented in a time division multiplexing manner, that is, the operating state of the touch display panel may include a touch state and a display state. When the touch display panel works, the touch display panel is continuously switched between a touch state and a display state so as to detect the touch operation of a user while displaying an image.
Specifically, when the touch display panel is in a display state, the touch display panel serves as a common substrate, and each touch sensing element 113 serves as a common electrode. The control chip 170 controls each input terminal of the channel selector 151 to be conducted with the output terminal of the channel selector 151, and loads the display driving signal to the touch sensing element 113 connected to each of the channel selectors 151 through each channel selector 151. Then, a display image signal is applied to the pixel array to form a pixel array electric field between the pixel array and the common electrode (the touch sensing element 113).
