Description

Technical Field

[0001] This disclosure relates to the field of touch panel technology, and in particular to a touch panel, touch detection method, device, electronic device, storage medium, and computer program product. Background Art

[0002] Currently, touch panels are increasingly being used in various electronic devices, becoming an important intermediate interface device for user interaction with electronic products. Touch panels can be mainly divided into several categories, such as resistive, capacitive, and infrared. Among them, due to the structural advantages, high light transmittance, and long lifespan of capacitive touch panels, most electronic devices use capacitive touch panels as human-computer interaction interfaces.

[0003] In related technologies, the driving module outputs a driving signal to drive the cross-arranged first and second electrodes, enabling the detection of the coupling capacitance between them. When a finger touches the surface, a current flows into the finger, causing a change in the detected coupling capacitance between the first and second electrodes, thus determining the touch point location. However, the methods used in these technologies to determine the touch point location often lack flexibility, resulting in an inability to determine the touch point location flexibly and accurately.

[0049] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0050] Figure 1 This is a schematic diagram of the structure of a touch panel according to an exemplary embodiment. Figure 1 ,like Figure 1 As shown, the touch panel includes:

[0051] At least two first electrodes 101 arranged along a first direction;

[0052] At least two second electrodes 102 arranged along a second direction, the first direction intersecting the second direction;

[0053] The driving module 103 is connected to each of the first electrodes 101 and each of the second electrodes 102 respectively; the driving module 103 is configured to: in response to touch operation, output driving signals in a time-division manner to drive each of the first electrodes 101 and / or each of the second electrodes 102.

[0054] Among them, the objects and / or number of times the driving module 103 outputs driving signals are different for different types of touch operations; the number of touch objects corresponding to different types of touch operations is different.

[0055] The touch panel proposed in this disclosure can be applied to electronic devices. Here, the electronic device may include a terminal device, such as a mobile terminal or a fixed terminal. The mobile terminal may include devices such as mobile phones, tablets, laptops, and wearable electronic devices. The fixed terminal may include desktop computers, smart TVs, and in-vehicle devices.

[0056] In this embodiment of the disclosure, the touch panel may include a driving module, a plurality of first electrodes arranged along a first direction and a plurality of second electrodes arranged along a second direction, and a plurality of signal lines connecting the plurality of first electrodes, the plurality of second electrodes and the driving module.

[0057] In some embodiments, the specific directions of the first direction and the second direction are not limited; it is only necessary to ensure that the first direction and the second direction can intersect.

[0058] For example, the first direction can be a horizontal direction, and at least two first electrodes arranged along the first direction can be electrodes arranged in a horizontal direction (not shown in the figure). The second direction can be a vertical direction, and at least two second electrodes arranged along the second direction can be electrodes arranged in a vertical direction (not shown in the figure).

[0059] For example, the first direction can be a vertical direction, and at least two first electrodes arranged along the first direction can be electrodes arranged along the vertical direction (e.g., ...). Figure 1 (As shown). The second direction can be horizontal, and at least two second electrodes arranged along the second direction can be electrodes arranged horizontally (e.g., Figure 1 (As shown).

[0060] It should be noted that when the first and second directions intersect, there is an overlapping region between the first electrode arranged along the first direction and the second electrode arranged along the second direction. Within this overlapping region, a coupling capacitance exists between the first and second electrodes.

[0061] In some embodiments, each first electrode can form an overlapping region with all the second electrodes, and each second electrode can form an overlapping region with all the first electrodes. Within the overlapping region of the first and second electrodes, there is a coupling capacitance between the first and second electrodes.

[0062] In some embodiments, the first electrode can be a single-piece conductive sheet or a conductive sheet formed by electrically connecting multiple electrode sheets. The second electrode can also be a single-piece conductive sheet or a conductive sheet formed by electrically connecting multiple electrode sheets. It is understood that the structure of the second electrode can be the same as or different from that of the first electrode. For example, if the first electrode is a single-piece conductive sheet, then the second electrode can be a conductive sheet formed by electrically connecting multiple electrode sheets.

[0063] In some embodiments, the driving module may be a touch chip, for example, the touch chip may be a display driver integrated circuit (DDIC) chip for a touch panel.

[0064] In this embodiment, the driving module outputs a driving signal that can activate and scan the sensing area of ​​the touch panel, i.e., activate and scan the touch sensor. The driving signal can periodically scan each of the first electrodes or second electrodes on the touch sensor, enabling the touch panel to continuously monitor and respond to external touch operations. Here, the driving signal can be a voltage signal. The driving module can continuously output the driving signal or periodically; this embodiment does not limit this.

[0065] In some embodiments, the driving module outputs a driving signal to drive either the first electrode or the second electrode at the same time. That is, at the same time, the driving module can drive one of the first electrode and the second electrode. The driving module may not output driving signals to the first electrode and the second electrode simultaneously, and the driving module may not drive the first electrode and the second electrode simultaneously.

[0066] In some embodiments, the driving module can be configured to output a first number of driving signals to drive all first electrodes and all second electrodes when the touch operation is a first type of touch operation; wherein, the driving module outputs driving signals to at least two first electrodes or at least two second electrodes at a time; the number of touch objects corresponding to the first type of touch operation is one. When the touch operation is a second type of touch operation, the driving module can output a second number of driving signals to drive all first electrodes and / or all second electrodes; the driving module outputs driving signals to one first electrode or one second electrode at a time; the number of touch objects corresponding to the second type of touch operation is at least two. The first number can be less than the second number.

[0067] In some embodiments, the first count may be less than a preset quantity, and the second count may be greater than or equal to the preset quantity. The preset quantity may be the number of the first electrode or the second electrode, or the preset quantity may be the total number of the first electrode and the second electrode.

[0068] In some embodiments, the drive module can be connected to the first electrode via a first connecting line, and different first electrodes correspond to different first connecting lines; the drive module can be connected to the second electrode via a second connecting line, and different second electrodes correspond to different second connecting lines.

[0069] Here, by connecting the drive module and the first electrode, the drive module can output a drive signal to the corresponding first electrode through the connected first connection; similarly, by connecting the drive module and the second electrode, the drive module can output a drive signal to the corresponding second electrode through the connected second connection. This ensures that the drive module can flexibly output drive signals to different objects to adapt to different types of touch operations.

[0070] In some embodiments, the driving module includes a first driving sub-module and a second driving sub-module; wherein the first driving sub-module is connected to each of the first electrodes via a first connecting line and configured to output a driving signal to at least one of the first electrodes; the second driving sub-module is connected to each of the second electrodes via a second connecting line and configured to output a driving signal to at least one of the second electrodes. Here, the first driving sub-module and the second driving sub-module can be combined to independently output driving signals to the first electrode or the second electrode.

[0071] In some embodiments, a first transistor can be disposed between the first driving sub-module and each first electrode, with different first transistors corresponding to different first electrodes; the first connection line between the driving module and each first electrode can be turned on or off by controlling the base current of the first transistor. A second transistor can be disposed between the second driving sub-module and each second electrode, with different second transistors corresponding to different second electrodes. The second connection line between the driving module and each second electrode can be turned on or off by controlling the base current of the second transistor.

[0072] Here, the types of the first transistor and the second transistor can be the same or different. For example, the first transistor can be an NPN transistor and the second transistor can be a PNP transistor. This disclosure does not limit this.

[0073] In the specific implementation, when the base current of the first transistor is zero, the first transistor is in the off state, and almost no current flows between the collector and emitter of the first transistor. This indicates that the first connection between the driving module and the first electrode is broken, and the driving module cannot send a driving signal to the corresponding first electrode. However, when the base current of the first transistor increases to a certain level, the first transistor is in the saturation state, and the resistance between the collector and emitter of the first transistor becomes smaller, allowing current to flow. This indicates that the second connection between the driving module and the first electrode is connected, and the driving module can send a driving signal to the corresponding first electrode. Here, the second transistor operates on the same principle as the first transistor, and will not be described in detail here.

[0074] In some embodiments, the drive module may have multiple output ports. Exemplarily, the drive module may include a first output port and a second output port. The first output port is connected to each of the first electrodes via a first connection line, and the second output port is connected to each of the second electrodes via a second connection line. The drive module may output a drive signal to at least one first electrode based on the first output port, and output a drive signal to at least one second electrode based on the second output port. Here, different output ports of the same drive module can be used to independently output drive signals to the first or second electrodes.

[0075] In some embodiments, a first transistor can be disposed between the first output port and each first electrode, with different first transistors corresponding to different first electrodes; the first connection line between the first output port of the driving module and each first electrode can be turned on or off by controlling the base current of the first transistor. A second transistor can be disposed between the second output port and each second electrode, with different second transistors corresponding to different second electrodes. The second connection line between the second output port of the driving module and each second electrode can be turned on or off by controlling the base current of the second transistor.

[0076] Here, since the driving module sends driving signals to all first electrodes at the first moment and driving signals to all second electrodes at the second moment, at the first moment, when the first transistor is in the on state, the second transistor is in the off state; and at the second moment, when the first transistor is in the off state, the second transistor is in the on state.

[0077] In some embodiments, the touch panel may further include: a sensing circuit connected to each of the first electrodes and each of the second electrodes, configured to detect each coupling capacitance between the first electrodes and the second electrodes; and a processing module configured to determine touch parameters based on the change in each coupling capacitance between the first electrodes and the second electrodes.

[0078] It should be noted that the touch parameters here can be the first touch parameters, which indicate the touch position of the touch object on the touch panel. The touch object can be any object that performs touch operations on the touch panel. For example, the touch object can be a user's finger, or it can be a stylus used to perform touch operations on the touch panel. Here, the specific type of touch object is not limited, as long as it is ensured that the touch object can trigger a change in the coupling capacitance between the first and second electrodes when it touches or approaches the touch panel.

[0079] It should be noted that a coupling capacitance exists between the first electrode and the second electrode. However, when the driving module does not output a driving signal to drive the first electrode and / or the second electrode, i.e., when there is no activated electric field, the sensing circuit cannot detect the coupling capacitance between the first electrode and the second electrode. When the driving module outputs a driving signal to drive the first electrode and / or the second electrode, i.e., when an activated electric field is present, the sensing circuit can detect the coupling capacitance between the first electrode and the second electrode.

[0080] In some embodiments, the sensing circuit is configured to detect respective coupling capacitances between the driving electrode and the sensing electrode; the processing module is configured to determine touch parameters based on the changes in the respective coupling capacitances between the driving electrode and the sensing electrode. The driving electrode may be one of the first electrode and the second electrode that receives a driving signal, and the sensing electrode may be one of the first electrode and the second electrode that does not receive a driving signal. Furthermore, there is an overlapping area between the sensing electrode and the driving electrode. A detectable coupling capacitance exists between the driving electrode and the sensing electrode.

[0081] In some embodiments, the touch panel includes: at least two first electrodes arranged along a first direction; at least two second electrodes arranged along a second direction, the first direction intersecting the second direction; a processing module configured to output a corresponding control signal in response to a touch operation; wherein the control signals corresponding to different types of touch operations are different; and a driving module connected to the processing module, each of the first electrodes, and each of the second electrodes; the driving module is configured to: output driving signals in a time-division manner based on the control signals to drive each of the first electrodes and / or each of the second electrodes; and the driving module outputs driving signals to different objects and / or on different numbers of times for different control signals.

[0082] It should be noted that in related technologies, for all types of touch operations, the touch panel controls the driving module to use a uniform high-power driving method to drive the first electrode and / or the second electrode to determine the touch point position. This detection method, which controls the driving module to output a driving signal to detect the touch point position, has low flexibility and high power consumption.

[0083] Based on this, in this embodiment, the touch panel can use a driving module to output driving signals to the cross-arranged first and second electrodes in response to touch operations. Furthermore, the target and / or number of times the driving module outputs driving signals differs for different types of touch operations; the number of touch targets corresponding to different types of touch operations also differs. Thus, compared to using a high-power driving method to drive each first and second electrode for all types of touch operations, in this embodiment, the driving module can flexibly adapt to different types of touch operations, outputting driving signals to different targets and / or outputting driving signals a different number of times. This reduces power consumption while ensuring flexibility in touch detection.

[0084] Figure 3 This is a schematic diagram of the structure of a touch panel according to an exemplary embodiment. Figure 3 ,like Figure 3 As shown, the drive module 103 is configured as follows:

[0085] When the touch operation is a first type of touch operation, a drive signal is sent to all first electrodes 101 at a first moment to drive all first electrodes 101; and a drive signal is sent to all second electrodes 102 at a second moment to drive all second electrodes 102.

[0086] Among them, the number of touch objects corresponding to the first type of touch operation is a single one, which is different in the first moment and the second moment.

[0087] It should be noted that, in the case of a first type of touch operation, in order to facilitate the detection of touch parameters on the touch panel, the driving module can send a driving signal to all first electrodes at the first moment, so that all first electrodes that receive the driving signal become driving electrodes and all second electrodes that do not receive the driving signal become sensing electrodes; the driving module can also send a driving signal to all second electrodes at the second moment, so that all second electrodes that receive the driving signal become driving electrodes and all first electrodes that do not receive the driving signal become sensing electrodes.

[0088] Here, the first moment and the second moment are different. The first moment and the second moment can be continuous in time series, that is, the second moment is the next moment after the first moment; the first moment and the second moment can also be discontinuous in time series, that is, the second moment is not the next moment after the first moment. This disclosure does not limit this.

[0089] In some embodiments, the driving module can be configured to: in the case of a first type of touch operation, at a first moment, turn on all first connected lines and turn off all second connected lines to send a driving signal to all first electrodes; at a second moment, turn on all second connected lines and turn off all first connected lines to send a driving signal to all second electrodes. In some embodiments, a first transistor can be disposed on the first connected line, and a second transistor can be disposed on the second connected line. The first connected line can be turned on or off by controlling the reference current in the first transistor. The second connected line can be turned on or off by controlling the reference current in the second transistor.

[0090] In some embodiments, a third connection line can be provided between the driving module and all the first electrodes, and a fourth connection line can be provided between the driving module and all the second electrodes. When the touch operation is a first type of touch operation, the driving module can activate the third connection line at a first moment to output a driving signal to all the first electrodes, and can activate the fourth connection line at a second moment to output a driving signal to all the second electrodes.

[0091] In some embodiments, a third transistor may be disposed on a third connection line and a fourth transistor may be disposed on a fourth connection line. The connection between the drive module and all first electrodes may be turned on or off by controlling the base current of the third transistor, and the connection between the drive module and all second electrodes may be turned on or off by controlling the base current of the fourth transistor.

[0092] Here, the third transistor and the fourth transistor can be of the same type or different. For example, the third transistor can be an NPN transistor and the fourth transistor can be a PNP transistor. This disclosure does not limit this.

[0093] In the specific implementation, when the base current of the third transistor is zero, the third transistor is in the off state, and almost no current flows between the collector and emitter of the third transistor. This indicates that the third connection between the drive module and all the first electrodes is broken, and the drive module cannot send drive signals to any of the first electrodes. However, when the base current of the third transistor increases to a certain level, the third transistor is in the saturation state, and the resistance between the collector and emitter of the third transistor becomes smaller, allowing current to flow. This indicates that the third connection between the drive module and all the first electrodes is connected, and the drive module can send drive signals to all the first electrodes. Here, the working principle of the third transistor is the same as that of the fourth transistor, and will not be elaborated further.

[0094] Here, since the driving module sends driving signals to all first electrodes at the first moment and driving signals to all second electrodes at the second moment, at the first moment, when the third transistor is in the on state, the fourth transistor is in the off state; while at the second moment, when the third transistor is in the off state, the fourth transistor is in the on state.

[0095] In some embodiments, a first connecting line and a third connecting line are provided between the driving module and the first electrode, and the first connecting line and the third connecting line are connected in parallel. A second connecting line and a fourth connecting line are provided between the driving module and the second electrode, and the second connecting line and the fourth connecting line are connected in parallel. When the touch operation is a first type of touch operation, the driving module turns on the third connecting line at a first moment and turns off all the first connecting lines, the second connecting line, and the fourth connecting line; at a second moment, it turns on the fourth connecting line and turns off all the first connecting lines, the second connecting line, and the third connecting line.

[0096] In some embodiments, the first and third connecting lines are connected in series, and the driving module can be connected to each first electrode sequentially through one third connecting line and multiple first connecting lines; different first electrodes correspond to the same first connecting line, and different first electrodes correspond to different second connecting lines. The second and fourth connecting lines are connected in series, and the driving module can be connected to each second electrode sequentially through one fourth connecting line and multiple second connecting lines; different second electrodes correspond to the same second connecting line, and different second electrodes correspond to different fourth connecting lines. Here, when the touch operation is a first type of touch operation and the first and third connecting lines are connected in series, all first and third connecting lines can be turned on at a first moment to output driving signals to all first electrodes. All second and fourth connecting lines can be turned on at a second moment to output driving signals to all second electrodes.

[0097] In some embodiments, Figure 2 This is a schematic diagram illustrating the structure of a touch detection method according to an exemplary embodiment, such as... Figure 2 As shown, the driving module can sequentially send driving signals to the second electrode, thereby determining the first touch parameters by driving the second electrode row by row at different times. In specific implementation, the first electrode may include RX1, RX2, RX3, RX4, and RX5 electrodes (e.g., ...). Figure 2 (as shown); the second electrode may include: TX1 electrode, TX2 electrode, TX3 electrode, TX4 electrode, TX5 electrode (as shown). Figure 2(As shown). At time T1, electrode TX1 is driven; at time T2, electrode TX2 is driven; and so on, until electrode TX5 is driven at time T5, until all driving is completed at time T5. If the duration of each drive is T, the total drive duration is 5T, and the power consumption is 5T*K; where K is the number of electrodes scanned per unit time. Therefore, this detection method has a long drive time, high power consumption, and low detection rate, which is not conducive to improving the touch reporting rate. In addition, although power consumption can be reduced by decreasing the duration T of each electrode drive, since the duration T is related to the signal-to-noise ratio, the smaller T is, the more susceptible it is to noise interference, which is not conducive to determining the touch parameters.

[0098] In this embodiment of the present disclosure, since it is not necessary to drive the first electrode or the second electrode row by row, a driving signal can be sent to all the first electrodes at the first moment to drive all the first electrodes at the same time; a driving signal can be sent to all the second electrodes at the second moment to drive all the second electrodes at the same time. Therefore, the number of driving times can be reduced and the driving time can be shortened, thereby reducing power consumption while ensuring the touch reporting rate.

[0099] In some embodiments, the touch panel includes: at least two first electrodes arranged along a first direction; at least two second electrodes arranged along a second direction, the first direction intersecting the second direction; a processing module configured to output a first control signal when the touch operation is a first type of touch operation; and a driving module connected to the processing module, each of the first electrodes, and each of the second electrodes; the driving module is configured to: based on the first control signal, send a driving signal to all the first electrodes at a first moment to drive all the first electrodes; and send a driving signal to all the second electrodes at a second moment to drive all the second electrodes.

[0100] In this embodiment, compared to the method of driving each first electrode column-by-column or each second electrode row-by-row at different times when there is only one touch object, in this embodiment, when there is only one touch object, the driving module outputs driving signals to all first electrodes at a first time to determine the second electrode near which the single touch object is located, and outputs driving signals to all second electrodes at a second time to determine the first electrode near which the single touch object is located. By combining the intersection of the first and second electrodes where coupling capacitance can be generated, the touch position of the touch object on the touch panel is determined. Thus, while ensuring that the specific touch position of a single touch object can be determined, the number of driving operations can be reduced, the touch reporting rate can be improved, and power consumption can be reduced.

[0101] In some embodiments, please refer again Figure 1 and Figure 2 Drive module 103 is configured as follows:

[0102] When the touch operation is a type II touch operation, drive signals are sent sequentially to each first electrode 101 to drive each first electrode 101 in a time-division manner; and / or, drive signals are sent sequentially to each second electrode 102 to drive each second electrode 102 in a time-division manner.

[0103] Among them, the number of touch objects corresponding to the second type of touch operation is at least two.

[0104] It should be noted that, in the case of a second type of touch operation, in order to accurately detect the touch parameters on the touch panel, the driving module can sequentially send driving signals to each of the first electrodes, so that the first electrode that receives the driving signal acts as the driving electrode and the second electrode that does not receive the driving signal acts as the sensing electrode; and / or, the driving module can sequentially send driving signals to each of the second electrodes, so that the second electrode that receives the driving signal acts as the driving electrode and the first electrode that does not receive the driving signal acts as the sensing electrode.

[0105] In some embodiments, see Figure 2 The first electrode may include electrodes RX1, RX2, RX3, RX4, and RX5; the second electrode may include electrodes TX1, TX2, TX3, TX4, and TX5. In the case of a second type of touch operation, the driving module may sequentially drive electrodes RX1 to RX5, and / or the driving module may sequentially drive electrodes TX1 to TX5.

[0106] In some embodiments, the driving module may be configured to: sequentially turn on each of the first connecting lines and disconnect all the second connecting lines when the touch operation is a second type of touch operation, so as to sequentially send driving signals to each of the first electrodes. And / or, sequentially turn on each of the second connecting lines and disconnect all the first connecting lines, so as to sequentially send driving signals to each of the second electrodes.

[0107] In some embodiments, the driving module may be configured to: in the case that the first and third connected lines are connected in series and the touch operation is a second type of touch operation, connect the third connected line and disconnect the fourth connected line, and sequentially connect each of the first connected lines and disconnect all the second connected lines; and / or connect the fourth connected line and disconnect the third connected line, and sequentially connect each of the second connected lines and disconnect all the first connected lines.

[0108] In some embodiments, when the first and third connected lines are connected in parallel and the touch operation is a second type of touch operation, the third and fourth connected lines are disconnected, and each of the first connected lines is connected in sequence while all the second connected lines are disconnected; and / or, the fourth and third connected lines are disconnected, and each of the second connected lines is connected in sequence while all the first connected lines are disconnected.

[0109] In some embodiments, the touch panel includes: at least two first electrodes arranged along a first direction; at least two second electrodes arranged along a second direction, the first direction intersecting the second direction; a processing module configured to output a second control signal when the touch operation is a second type of touch operation; and a driving module connected to the processing module, each of the first electrodes, and each of the second electrodes; the driving module is configured to: based on the second control signal, sequentially send driving signals to each of the first electrodes to drive each of the first electrodes; and / or, sequentially send driving signals to each of the second electrodes to drive each of the second electrodes.

[0110] In this embodiment, the driving module is configured to: sequentially send driving signals to each first electrode to drive each first electrode in a time-division multiplexing manner when the touch operation is a second type of touch operation; and / or sequentially send driving signals to each second electrode to drive each second electrode in a time-division multiplexing manner; wherein the number of touch objects corresponding to the second type of touch operation is at least two. Here, when the number of touch objects is at least two, compared to the related art method of separately determining the touch position of the touch object relative to the first electrode and the touch position relative to the second electrode, which leads to erroneous touch positions, this embodiment can accurately locate the precise touch position of the touch object relative to the first electrode and the second electrode by sequentially sending driving signals to each first electrode and / or sequentially sending driving signals to each second electrode. This ensures the accuracy of the determined touch position and the accuracy of the touch reporting.

[0111] Figure 4 This is a schematic diagram of the structure of a touch panel according to an exemplary embodiment. Figure 4 ,like Figure 4 As shown, the touch panel also includes:

[0112] The gating circuit 104 has its input terminal connected to the drive module 103, and its output terminal connected to all the first electrodes 101 via the first line 105 and to all the second electrodes 102 via the second line 106.

[0113] The gating circuit 104 is configured to: turn on or off the connection between the drive module 103 and at least one first electrode 101, and send a drive signal to the first electrode 101 in the on state via the first line 105; and / or, turn on or off the connection between the drive module 103 and at least one second electrode 102, and send a drive signal to the second electrode 102 in the on state via the second line 106.

[0114] Understandably, to facilitate the connection or disconnection of the first lines between the drive module and all first electrodes, and the second lines between the drive module and all second electrodes, a gating circuit can be provided between the drive module, all first electrodes, and all second electrodes. The input of the gating circuit is connected to the drive module, and the output of the gating circuit is connected to each first electrode via the first line and to each second electrode via the second line. Based on the path selected by the gating circuit, the on / off state of the first lines between the drive module and each first electrode, and the state of the second lines between the drive module and each second electrode are adjusted.

[0115] Here, at the same time, the on / off state of the first line and the on / off state of the second line can be different.

[0116] In some embodiments, the first line may include any of the first connecting lines and / or the third connecting lines described above in this disclosure, and the second line may include any of the second connecting lines and / or the fourth connecting lines described above in this disclosure.

[0117] In some embodiments, if the first line includes one path, the first line may be a third connecting path. If the first line includes at least two paths, the first line may include all of the first connecting paths. If the second line includes one path, the first line may be a fourth connecting path. If the second line includes at least two paths, the second line may include all of the fourth connecting paths.

[0118] In some embodiments, the on / off state of the first line and the second line being different at the same time can mean that, at the same time, if the first or second connected line is on, the on / off state of the first connected line and the second connected line in the second line are different. That is, the first connected line and the second connected line in the first line are not on simultaneously. And / or, at the same time, if the third or fourth connected line is on, the on / off state of the third connected line and the fourth connected line in the first line are different. That is, the third connected line and the fourth connected line in the first line are not on simultaneously.

[0119] In some embodiments, the gating circuit may include a switch, for example, a single-pole double-throw switch or a logic gate; the gating circuit may also include multiple switches, for example, multiple transistors, multiple field-effect transistors (MOSFETs) or multiple relays, and the embodiments disclosed herein do not limit this.

[0120] In some embodiments, the selection circuit may include logic gates, which can control the on / off state of the first line and the second line through logical operations according to different input signals. When the input signal meets a specific condition (e.g., the input signal is a low-level signal), the logic gate outputs a high-level signal, which enables the first line to be turned on and the second line to be turned off, allowing the drive module to send drive signals to each first electrode through the first line. Conversely, when the input signal does not meet a specific condition (e.g., the input signal is a high-level signal), the logic gate outputs a low-level signal, which enables the second line to be turned on and the first line to be turned off, allowing the drive module to send drive signals to each second electrode through the second line. Here, the logic gate can be an AND gate, an OR gate, or a NOT gate; this disclosure does not limit the specific logic gates used.

[0121] In practical implementation, taking the NOT gate as an example, the input signal is connected to the input terminal of the NOT gate, and the output terminal of the NOT gate is connected to the control terminal of the first line. The output signal of the NOT gate can be connected to the control terminal of the second line through a buffer or direct connection. The first line is set to conduct when it receives a high level, and the second line is set to conduct when it receives a low level. When the input signal is high, the output of the NOT gate is low. At this time, the first line is open and the second line is open, and the driver module sends a drive signal to each second electrode through the second line. When the input signal is low, the output of the NOT gate is high. At this time, the first line is open and the second line is open, and the driver module sends a drive signal to each first electrode through the second line.

[0122] In other embodiments, when the selection circuit may include multiple switches, a first MOS transistor may be placed between the driving module and each first electrode, and the first line may be turned on or off by controlling the gate voltage of the first MOS transistor. A second MOS transistor may be placed between the driving module and each second electrode, and the second line may be turned on or off by controlling the gate voltage of the second MOS transistor.

[0123] In the specific implementation, when the gate voltage of the first MOSFET is zero or low, there is no conductive path between the source and drain of the first MOSFET, and current cannot flow, indicating that the first circuit is disconnected, and the drive module cannot send drive signals to the first electrodes through the first circuit. However, when the gate voltage of the first MOSFET gradually increases to reach the critical voltage value, the first MOSFET enters a saturation state, and current can flow between the source and drain of the first MOSFET, indicating that the first circuit is turned on, and the drive module can send drive signals to the first electrodes through the first circuit. Here, the second MOSFET operates on the same principle as the first MOSFET, and will not be described in detail here.

[0124] Here, since the driving module sends driving signals to each first electrode at the first moment and driving signals to each second electrode at the second moment, at the first moment, when the first MOSFET is in a saturated state, the second MOSFET is in a turned-off state; while at the second moment, when the first MOSFET is in a turned-off state, the second MOSFET is in a saturated state.

[0125] In some embodiments, the gating circuit includes a fifth switch having a fixed end and a movable end, the fixed end being connected to a drive module, and the movable end being connected to an end of a first line or an end of a second line.

[0126] Understandably, to simplify the circuit, a fifth switch with a fixed end and a movable end can be set as a selection circuit, so that the fixed end is connected to the drive module. When the movable end is connected to the end of the first line, the drive module sends a drive signal to all the first electrodes through the first line; when the movable end is connected to the end of the second line, the drive module sends a drive signal to all the second electrodes through the second line.

[0127] In some embodiments, the fifth switch may be a single-pole double-throw switch, which controls the connection between the active end of the single-pole double-throw switch and the line to connect or disconnect the first line and the second line.

[0128] In its implementation, the single-pole double-throw (SPDT) switch has one input terminal (which can be understood as a fixed terminal) and two output terminals. The input terminal is connected to the drive module, the first output terminal is connected to the first line, and the second output terminal is connected to the second line. When the movable end of the SPDT switch is connected to the first output terminal, it indicates that the first line is connected and the second line is disconnected, allowing the drive module to send drive signals to all first electrodes through the first line. Conversely, when the movable end of the SPDT switch is connected to the second output terminal, it indicates that the second line is connected and the first line is disconnected, allowing the drive module to send drive signals to all second electrodes through the second line.

[0129] In this embodiment of the disclosure, the selection circuit can be a fifth switch with a fixed end and a movable end, such that the fixed end of the fifth switch is connected to the drive module, and the movable end of the fifth switch is connected to the end of the first line or the end of the second line, thereby simplifying the circuit while enabling precise control of the drive module to send drive signals to each first electrode or to each second electrode.

[0130] In this embodiment, the touch panel further includes a gating circuit. The input terminal of the gating circuit is connected to the driving module, and the output terminal of the gating circuit is connected to each first electrode via a first line and to each second electrode via a second line. Thus, by setting the gating circuit, the first line can be selected to be activated, switching the first electrode as the driving electrode; or the second line can be selected to be activated, switching the second electrode as the driving electrode, thereby improving the convenience of switching driving electrodes.

[0131] Figure 5 This is a schematic diagram of the structure of a touch panel according to an exemplary embodiment. Figure 5 ,like Figure 5 As shown, the gating circuit 104 includes:

[0132] The first switch 107 is located between the drive module 103 and all the first electrodes 101. The first end of the first switch 107 is connected to the drive module 103, and the second end of the first switch 107 is connected to all the first electrodes through the first line 105.

[0133] The second switch 108 is located between the drive module and all the second electrodes 102. The first end of the second switch 108 is connected to the drive module 103, and the second end of the second switch 108 is connected to all the second electrodes through the second line 106.

[0134] At the same time, the opening and closing states of the first switch 107 and the second switch 108 are different.

[0135] It is understandable that when the first line is a single line and the second line is a single line, the selection circuit may include a first switch and a second switch. The first switch is positioned between the drive module and the first line, and the on / off state of the first line is adjusted based on the open / closed state of the first switch. Simultaneously, the second switch is positioned between the drive module and the second line, and the on / off state of the second line is adjusted based on the open / closed state of the second switch.

[0136] Specifically, at any given moment, the open / closed states of the first switch and the second switch are different. When the first switch is closed and the second switch is open, the first circuit is in a conductive state, and the drive module can send drive signals to each of the first electrodes through the first circuit. When the first switch is open and the second switch is closed, the second circuit is in a conductive state, and the drive module can send drive signals to each of the second electrodes through the second circuit.

[0137] In some embodiments, the first switch may be connected to a third connecting line in the first circuit, for turning on or off the third connecting line connected to the first switch. The second switch may be connected to a fourth connecting line in the second circuit, for turning on or off the fourth connecting line connected to the second switch.

[0138] Here, the first switch and the second switch can be of the same type. For example, the first switch can be a transistor and the second switch can also be a transistor. The first switch and the second switch can also be of different types. For example, the first switch can be a MOSFET and the second switch can be a transistor. This disclosure does not limit the types of switches.

[0139] In some embodiments, the first switch is a transistor, which is placed between the driving module and the first line. The first line is turned on or off by controlling the base current of the transistor. The second switch is a MOSFET, which is placed between the driving module and the second line. The second line is turned on or off by controlling the gate voltage of the MOSFET.

[0140] In this embodiment, the selection includes a first switch and a second switch. The first switch is connected to the ends of the drive module and the first circuit, respectively, and the second switch is connected to the ends of the drive module and the second circuit, respectively. Thus, based on the open / closed states of the first and second switches, the first and second circuits can be switched on or off, improving the convenience of switching the first or second electrode as the drive electrode.

[0141] Figure 6 This is a schematic diagram of the structure of a touch panel according to an exemplary embodiment. Figure 6 ,like Figure 6 As shown:

[0142] The first route, 105, consists of at least two routes;

[0143] The selection circuit 104 includes: at least two third switches 109 located between the drive module 103 and the first electrode 101; the first end of each third switch 109 is connected to the drive module 103, and the second end of each third switch 109 is connected to the first electrode 101 through the first line 105.

[0144] Among them, the first electrode 101 and the first line 105 corresponding to different third switches 109 are different; when the drive module 103 outputs a drive signal and the third switch 109 is closed, the drive signal is used to drive the first electrode 101 connected to the closed third switch 109.

[0145] It should be noted that when the driving module can send a driving signal to the first electrode and drive each first electrode based on the driving signal, each second electrode acts as a sensing electrode. To obtain the touch parameters of the touched object on the touch panel, multiple third switches can be set between the driving module and each first electrode, such that the first end of each third switch is connected to the driving module, and the second end of each third switch is connected to the corresponding first electrode through a first line. Thus, based on the open / closed state of each third switch, the on / off state of the first line between the driving module and each first electrode can be controlled to select the first electrode to be driven. This facilitates further accurate detection of touch parameters based on the coupling capacitance between the driven first electrode and the second electrode with overlapping areas with it, ensuring a high touch detection rate.

[0146] In some embodiments, where each second electrode serves as a driving electrode and each first electrode serves as a sensing electrode, the coupling capacitance between each driving electrode and each sensing electrode changes when a touch operation occurs. Based on this change, a first electrode that may be subject to a touch operation can be selected from among the first electrodes. Therefore, to facilitate further determination of the first touch parameter, a fourth switch can correspond to one first electrode. After locating the first electrode that may be subject to a touch operation, the first circuit corresponding to the first electrode can be turned on based on the closed state of the third switch corresponding to that first electrode, so as to facilitate the detection of the first touch parameter.

[0147] Here, the types of the third switches can be the same or different. Each third switch can correspond to one first electrode or multiple first electrodes, and this embodiment does not limit this.

[0148] Meanwhile, the first electrode and the first circuit are different for different third switches.

[0149] In some embodiments, if a third switch can correspond to a first electrode, after locating the first electrode that may be subject to touch operation, the first circuit corresponding to the first electrode can be turned on based on the closed state of the third switch corresponding to the first electrode, thereby further detecting the first touch parameter.

[0150] In other embodiments, if a third switch can correspond to two first electrodes, for example, if the third switch is a single-pole double-throw switch (SPS) corresponding to first electrode A and first electrode B, the fixed end of the SPS is connected to the drive module, the first output terminal is connected to first electrode A, and the second output terminal is connected to first electrode B. If the first electrode that may be subject to touch operation is located as first electrode A, the moving end of the SPS is connected to the first output terminal, activating the first circuit corresponding to first electrode A, thereby enabling further detection of touch parameters. If the first electrode that may be subject to touch operation is located as first electrode B, the moving end of the SPS is connected to the second output terminal, activating the first circuit corresponding to first electrode B, thereby enabling further detection of touch parameters.

[0151] In some embodiments, the third switch may be connected to the first connected line in the first circuit, and different third switches are connected to different first connected lines. The third switch is used to turn on or off the first connected line connected to the third switch.

[0152] In this embodiment, the touch panel further includes multiple third switches, each located between the driving module and each first electrode. The first end of each third switch is connected to the driving module, and the second end of each third switch is connected to the corresponding first electrode via a first line. Thus, the on / off state of each first line can be controlled by the open / closed state of each third switch, facilitating subsequent detection of the first touch parameters of the touch object, thereby improving the touch reporting rate.

[0153] Figure 7 This is a schematic diagram of the structure of a touch panel according to an exemplary embodiment. Figure 7 ,like Figure 7 As shown, the second route consists of at least two routes;

[0154] The selection circuit 104 includes at least two fourth switches 110 located between the drive module 103 and the second electrode 102; the first terminal of each fourth switch 110 is connected to the drive module 103, and the second terminal of each fourth switch 110 is connected to the second electrode 102 via a second line 106.

[0155] The second electrode 102 and the second line 106 corresponding to different fourth switches 110 are different; when the drive module 103 outputs a drive signal and the fourth switch 110 is closed, the drive signal is used to drive the second electrode 102 connected to the closed fourth switch 110.

[0156] It should be noted that when the driving module can send driving signals to the second electrodes and drive each second electrode based on the driving signals, each first electrode acts as a sensing electrode. To obtain the touch parameters of the touched object on the touch panel, multiple fourth switches can be set between the driving module and each second electrode, such that the first end of each fourth switch is connected to the driving module, and the second end of each fourth switch is connected to the corresponding second electrode through a second line. Thus, based on the open / closed state of each fourth switch, the on / off state of the second line between the driving module and each second electrode can be controlled respectively, facilitating the selection of the driven second electrode. Based on the coupling capacitance between the driven second electrode and the first electrode with an overlapping area, the touch parameters are further accurately detected.

[0157] In some embodiments, where each first electrode serves as a driving electrode and each second electrode serves as a sensing electrode, the coupling capacitance between each driving electrode and each sensing electrode changes when a touch operation occurs. Based on this change, a second electrode that may be subject to a touch operation can be selected from among the second electrodes. Therefore, to facilitate further determination of touch parameters, a fourth switch can correspond to at least one second electrode. After locating a second electrode that may be subject to a touch operation, the second circuit corresponding to that second electrode can be activated based on the closed state of the fourth switch corresponding to that second electrode, thereby facilitating the detection of touch parameters.

[0158] Here, the types of the fourth switches can be the same or different. Each fourth switch can correspond to one second electrode or multiple second electrodes, and this disclosure does not limit this.

[0159] Meanwhile, the second electrode and the second circuit corresponding to different fourth switches are different.

[0160] In some embodiments, if a fourth switch can correspond to a second electrode, after locating the second electrode that may be subject to touch operation, the second circuit corresponding to the second electrode can be turned on based on the closed state of the fourth switch corresponding to the second electrode, thereby further detecting the touch parameters.

[0161] In other embodiments, if a fourth switch can correspond to two second electrodes, for example, if the fourth switch is a single-pole double-throw switch (SPS), and the SPS corresponds to second electrode A and second electrode B, the fixed end is connected to the drive module, the first output terminal is connected to second electrode A, and the second output terminal is connected to second electrode B. If the second electrode that may be subject to touch operation is located as second electrode A, the moving end of the SPS is connected to the first output terminal, activating the second circuit corresponding to second electrode A, thereby enabling further detection of touch parameters. If the second electrode that may be subject to touch operation is located as second electrode B, the moving end of the SPS is connected to the second output terminal, activating the second circuit corresponding to second electrode B, thereby enabling further detection of touch parameters.

[0162] In some embodiments, the touch panel may include a first switch and a second switch, or a third switch and a fourth switch. Alternatively, the touch panel may include a first switch, a second switch, a third switch, and a fourth switch. The first switch may be connected in series with the third switch, or the first switch may be connected in parallel with the third switch. The second switch may be connected in parallel with the fourth switch, or the second switch may be connected in series with the fourth switch. Alternatively, the touch panel may include a third switch, a fourth switch, and a first switch; wherein the first switch may be connected in series with the third switch, or the first switch may be connected in parallel with the third switch. Alternatively, the touch panel may include a third switch, a fourth switch, and a second switch; wherein the fourth switch may be connected in parallel with the second switch, or the fourth switch may be connected in series with the second switch. The combination of the first, second, third, and fourth switches is not limited here.

[0163] In some embodiments, the gating circuit can be configured such that, in the case of a first type of touch operation, if the first switch and the third switch are connected in series and the second switch and the fourth switch are connected in series, the first switch and all the third switches can be closed at a first moment to cause the driving module to output a driving signal to all the first electrodes. The second switch and all the fourth switches can be closed at a second moment to cause the driving module to output a driving signal to all the second electrodes. At the same time, the first switch and the third switch have different open / closed states, and the third switch and the fourth switch have different open / closed states.

[0164] In some embodiments, the gating circuit can be configured such that, in the case of a first type of touch operation, if the first switch and the third switch are connected in parallel and the second switch and the fourth switch are connected in parallel, the first switch and / or all the third switches can be closed at a first moment to cause the driving module to output a driving signal to all the first electrodes. The second switch and / or all the fourth switches can be closed at a second moment to cause the driving module to output a driving signal to all the second electrodes. It should be noted that, when driving the first electrode, the second switch and all the fourth switches are disconnected. When driving the second electrode, the first switch and all the third switches are disconnected.

[0165] In some embodiments, the gating circuit can be configured such that, when the touch operation is a second type of touch operation, if the first switch and the third switch are connected in series and the second switch and the fourth switch are connected in series, the first switch can be closed and the second switch and all the fourth switches can be opened, and each of the third switches can be closed in sequence, so that the driving module outputs driving signals to each of the first electrodes in sequence; and / or, the second switch can be closed and the first switch and all the third switches can be opened, and the fourth switch can be closed in sequence, so that the driving module outputs driving signals to each of the second electrodes in sequence.

[0166] In some embodiments, the gating circuit can be configured such that, when the touch operation is a second type of touch operation, if the first switch and the third switch are connected in parallel and the second switch and the fourth switch are connected in parallel, the first switch and the second switch can be disconnected; by sequentially closing the third switch and disconnecting all the fourth switches in the gating circuit, the driving module can be controlled to send driving signals to each first electrode sequentially through the closed first switch, and / or, each fourth switch can be sequentially closed and all the third switches can be disconnected, so as to control the driving module to send driving signals to each second electrode sequentially through the closed fourth switch.

[0167] In some embodiments, the fourth switch can be connected to the second connecting line in the second circuit, and different fourth switches can be connected to different second connecting lines. The fourth switch is used to turn on or off the second connecting line connected to it.

[0168] In this embodiment, the touch panel further includes a plurality of fourth switches, each fourth switch being located between the driving module and each first electrode. The first end of each fourth switch is connected to the driving module, and the second end of each fourth switch is connected to the corresponding second electrode via a second line. Thus, the on / off state of each second line can be controlled by the open / closed state of each fourth switch, facilitating subsequent detection of touch parameters of the touch object and thereby improving the touch reporting rate.

[0169] Figure 8 This is a schematic diagram of the structure of a touch panel according to an exemplary embodiment. Figure 8,like Figure 8 As shown, the touch panel also includes:

[0170] At least two first integrators 111 are provided, each first integrator 111 being connected to a corresponding first electrode 101. The first integrator 111 is configured to convert the first coupling capacitor formed between each first electrode 101 and the second electrode 102 receiving the drive signal into a first voltage signal corresponding to each first electrode 101 when the drive module 103 drives the second electrode 102.

[0171] At least two second integrators 112 are provided, each second integrator 112 being connected to a corresponding second electrode 102. The second integrator 112 is configured to convert the second coupling capacitor formed between each second electrode 102 and the first electrode 101 receiving the drive signal into a second voltage signal corresponding to each second electrode 102 when the drive module 103 drives the first electrode 101.

[0172] It should be noted that the sensing circuit can be any of the sensing circuits described above in this disclosure, including a first integrator and a second integrator. The sensing circuit detects each of the first coupling capacitors and each of the second coupling capacitors through the first integrator and the second integrator.

[0173] It should be noted that when the turn-on circuit selects to turn on the second line between the drive module and the second electrode, a first coupling capacitor will be formed between each first electrode and the second electrode that receives the drive signal. In order to facilitate the determination of the touch parameters of the touch object based on each first coupling capacitor, multiple first integrators can be set to be connected to the corresponding first electrodes respectively. The first integrators will convert the first coupling capacitor formed between the first electrode and the second electrode that receives the drive signal into a signal to obtain the first voltage signal corresponding to the first electrode. This will enable the detection circuit to accurately analyze the first voltage signal to obtain the touch parameters.

[0174] Here, each first electrode is connected to a first integrator.

[0175] In some embodiments Figure 9 This is a schematic diagram of the structure of a touch panel according to an exemplary embodiment. Figure 9 ,like Figure 9As shown, the first integrator 111 includes a sixth switch 201, a first integrating capacitor 203, and a first amplifier 202. The sixth switch 201 is connected in parallel with the first integrating capacitor 203 and is configured to clear the charge stored on the first integrating capacitor 203. The first amplifier 202 is connected in parallel with the first integrating capacitor 203 and is connected to the first electrode 101. It is configured to receive the first voltage signal and adjust the gain of the first voltage signal. Thus, by highlighting the changing trend of the first voltage signal through the first integrating capacitor and amplifying the amplitude of the first voltage signal through the first amplifier, the detection circuit can easily analyze each first voltage signal to determine the first electrode where touch operation may occur.

[0176] It should be noted that when the turn-on circuit selects to turn on the first line between the drive module and the first electrode, a first coupling capacitor will be formed between each second electrode and the first electrode that receives the drive signal. In order to facilitate the determination of the touch parameters of the touch object based on each first coupling capacitor, multiple second integrators can be set to be connected to the corresponding second electrodes respectively. The second integrators will convert the second coupling capacitor formed between the second electrode and the first electrode that receives the drive signal into a signal to obtain the second voltage signal corresponding to the second electrode. This will enable the detection circuit to accurately analyze the second voltage signal to obtain the touch parameters.

[0177] Here, each second electrode is connected to a second integrator.

[0178] In some embodiments, Figure 10 This is a schematic diagram of the structure of a touch panel according to an exemplary embodiment. Figure 10 ,like Figure 10 As shown, the second integrator 112 includes a seventh switch 204, a second integrating capacitor 206, and a second amplifier 205. The seventh switch 204 is connected in parallel with the second integrating capacitor 206 and is configured to clear the charge stored on the second integrating capacitor 206. The second amplifier 205 is connected in parallel with the second integrating capacitor 110 and is connected to the second electrode 102. It is configured to receive the second voltage signal and adjust the gain of the second voltage signal. Thus, by highlighting the changing trend of the second voltage signal through the second integrating capacitor and amplifying the amplitude of the second voltage signal through the second amplifier, the detection circuit can easily analyze each second voltage signal to determine the second electrode where touch operation may occur.

[0179] In this embodiment, the touch panel further includes at least two first integrators, each connected to a corresponding first electrode. The first integrators convert the first coupling capacitance formed between each first electrode and a second electrode receiving the drive signal into a first voltage signal corresponding to the first electrode. Thus, by using multiple first integrators to process each first coupling capacitance, the detection circuit can accurately analyze the first voltage signal, thereby improving the accuracy of determining the touch parameters.

[0180] Simultaneously, the touch panel also includes at least two second integrators, each connected to a corresponding second electrode. This allows the second integrators to convert the second coupling capacitance formed between each second electrode and the second electrode receiving the drive signal into a second voltage signal corresponding to that electrode. Thus, by using multiple second integrators to process each second coupling capacitance, the detection circuit can accurately analyze the second voltage signal, thereby improving the accuracy of determining the touch parameters.

[0181] In some embodiments, the touch panel further includes:

[0182] The processing module is connected to each of the first integrators and the second integrators respectively, and is configured to determine the change of each of the first coupling capacitors based on each of the first voltage signals; and / or, determine the change of each of the second coupling capacitors based on each of the second voltage signals; and determine the first touch parameters of the touch object based on the change of each of the first coupling capacitors and / or the change of each of the second coupling capacitors.

[0183] The first touch parameter is used to indicate the touch position of the touch object on the touch panel.

[0184] Understandably, in order to improve the accuracy of determining the touch parameters of the touch object, the touch panel also includes a processing module. The first end of the processing module is connected to the driving module, and the second end of the processing module is connected to each of the first integrators, configured to determine the change in the first coupling capacitor based on the first voltage signal. At the same time, it is connected to each of the second integrators, configured to determine the change in the second coupling capacitor based on the second voltage signal. Finally, the touch parameters are determined based on the changes in the first coupling capacitors and the changes in the second coupling capacitors.

[0185] Here, the processing module includes a central processing unit (CPU) or a system-on-a-chip (SOC). The CPU or SOC is located on the motherboard of the electronic device.

[0186] Here, the first touch parameter is also used to indicate at least one of the following: trigger orientation, touch position, touch duration, and touch pressure sensing.

[0187] In some embodiments, after the processing module is connected to each of the first integrators, it can convert the first voltage signal into a first digital signal and determine the change in the first coupling capacitor based on the first digital signal. For example, the processing module can determine a preset digital signal when the user does not operate the touch panel; then it can calculate the difference between the currently obtained first digital signal and the preset digital signal to determine the change in the first coupling signal.

[0188] Since each first integrator is connected to the processing module simultaneously, the processing module can simultaneously determine the change in the first coupling capacitor based on each first voltage signal, which helps to improve the efficiency of determining touch parameters.

[0189] In other embodiments, after the processing module is connected to each of the second integrators, it can convert the second voltage signal into a second digital signal and determine the change in the second coupling capacitor based on the second digital signal. For example, the processing module can determine a preset digital signal when the user does not operate the touch panel; then it can calculate the difference between the currently obtained second digital signal and the preset digital signal to determine the change in the second coupling signal.

[0190] Since each second integrator is connected to the processing module simultaneously, the processing module can simultaneously determine the change in the second coupling capacitor based on each second voltage signal, which helps to improve the efficiency of determining touch parameters.

[0191] In some embodiments, a processing module is connected to a driving module. The processing module can be configured to output a control signal based on the number of touch objects, and the driving module outputs a driving signal in a driving mode indicated by the control signal. For example, when the number of touch objects is single, the processing module outputs a first control signal, and the driving module, in the driving mode indicated by the first control signal, sends a driving signal to all first electrodes at a first moment to drive all first electrodes, and sends a driving signal to all second electrodes at a second moment to drive all second electrodes.

[0192] In this embodiment of the present disclosure, the touch panel further includes a processing module, which is connected to each of the first integrators so that the processing module can determine the change in the first coupling capacitor based on the first voltage signal; at the same time, it is connected to each of the second integrators so that the processing module can determine the change in the second coupling capacitor based on the second voltage signal; then, based on the changes in the first coupling capacitors and the changes in the second coupling capacitors, the first touch parameters of the touch object can be determined, which on the one hand helps to improve the accuracy of determining the touch parameters, and on the other hand helps to improve the efficiency of determining the first touch parameters.

[0193] In related technologies, there are generally two touch scanning modes used to determine the first touch parameters: self-capacitance scanning mode and first mutual capacitance scanning mode. In self-capacitance scanning mode, the coupling capacitance between each first electrode and the ground terminal, and the coupling capacitance between each second electrode and the ground terminal, are scanned using self-capacitance. This mode can be used to detect the presence of a touch operation. However, due to its poor stability, self-capacitance scanning mode is difficult to accurately report touch points and cannot accurately determine the touch position. In first mutual capacitance scanning mode, the coupling capacitance between each first electrode and each second electrode is scanned using mutual capacitance to determine the touch position. In related technologies, regardless of the type of touch operation, in response to a touch operation, the system switches to the fully high-power first mutual capacitance scanning mode. In this mode, each first electrode and each second electrode needs to be scanned individually, resulting in high power consumption.

[0194] Based on this Figure 11 This is a flowchart illustrating a touch detection method according to an exemplary embodiment, such as... Figure 5 As shown, the method includes:

[0195] In step 111, in response to a touch operation on the touch panel, based on the type of touch operation, the driving module of the touch panel is controlled to output driving signals in stages to drive each of the first electrodes and / or each of the second electrodes of the touch panel; wherein, for different types of touch operations, the objects and / or the number of times the driving module outputs driving signals are different; the number of touch objects corresponding to different types of touch operations is different;

[0196] In step 112, the first coupling capacitance formed between each first electrode and the second electrode that receives the driving signal is detected, and / or the second coupling capacitance formed between each second electrode and the first electrode that receives the driving signal is detected.

[0197] In step 113, the first touch parameters of the touch object are determined based on the changes in each first coupling capacitor and / or each second coupling capacitor.

[0198] The first touch parameter is used to indicate the touch position of the touch object on the touch panel.

[0199] In some embodiments, the touch detection method proposed in this disclosure can be applied to electronic devices. Here, the electronic device may include a terminal device, such as a mobile terminal or a fixed terminal. The mobile terminal may include devices such as mobile phones, tablets, laptops, and wearable electronic devices. The fixed terminal may include desktop computers, smart TVs, and in-vehicle devices. In other embodiments, the touch detection method may also be applied to applications installed on the electronic device. The electronic device may be a device with a foldable screen.

[0200] In other embodiments, the touch detection method in this disclosure can be configured in a touch detection device, which can be located in an electronic device; this disclosure does not limit this. It should be noted that the execution entity in this disclosure can be a central processing unit (CPU) in the electronic device in hardware, and related background services in the electronic device in software; this is not limited.

[0201] In this embodiment, to facilitate continuous monitoring of touch operations on the touch panel, in response to a touch operation, based on the type of touch operation, the driving module of the touch panel outputs driving signals sequentially to drive each of the first electrodes and / or each of the second electrodes of the touch panel. Electrodes receiving driving signals are designated as driving electrodes, and electrodes with overlapping areas with the driving electrodes but not receiving driving signals are designated as sensing electrodes. The change in coupling capacitance between each driving electrode and each sensing electrode is determined. Then, based on the change in coupling capacitance, the first touch parameter of the touched object is determined. This embodiment proposes a more reasonable and power-saving touch detection method that can both ensure the user's touch performance experience and save power. This embodiment does not use an absolutely high-power mode to detect the first touch parameter, thus reducing battery consumption. This optimizes the power consumption level of the touch panel on the electronic device, primarily reducing the operating power consumption of the driving module (i.e., the touch chip), reducing power consumption of the electronic device, and improving the battery life of the electronic device.

[0202] In some embodiments, a stable coupling capacitance can be formed between the driving electrode and the sensing electrode of the touch panel. When a user's finger (or a user-operated stylus) touches the touch panel, it affects the electric field in the sensor, especially the part of the sensor that is in contact with the user's finger (or the user-operated stylus). This effect causes changes in the signal received by the receiver.

[0203] Specifically, when a user's finger approaches or touches a certain location on the sensor, capacitive coupling is formed between that location and the sensor. Since capacitive coupling changes the electric field distribution on the sensor, it affects the signal received by the receiver. Therefore, the touch chip can determine the specific location of the touch by detecting these changes in the signal.

[0204] In some embodiments, C(i, j) can be used to represent the corresponding coupling capacitance on the sensor, wherein, when the first electrode is arranged in a horizontal direction and the second electrode is arranged in a vertical direction, C(i, j) represents the coupling capacitance formed between the first electrode in the i-th row and the second electrode in the j-th column of the sensor array. Alternatively, when the first electrode is arranged in a vertical direction and the second electrode is arranged in a horizontal direction, C(i, j) represents the coupling capacitance formed between the second electrode in the i-th row and the first electrode in the j-th column of the sensor array.

[0205] In some embodiments, the presence of a touch operation can be detected using the self-capacitance scanning mode of the touch panel. When a finger touches the screen, due to the presence of the human body's electric field, a coupling capacitance is formed between the user and the touch panel. This coupling capacitance allows the finger to draw a small current from the contact point, causing a change in the coupling capacitance. In self-capacitance scanning mode, each horizontally arranged electrode and each vertically arranged electrode are detected sequentially. Based on the change in coupling capacitance before and after the touch, the horizontal and vertical coordinates are determined to determine whether a touch operation exists. It should be noted that because the touch parameters detected for the touch object in self-capacitance scanning mode are unstable, the presence of a touch operation can be determined first using self-capacitance scanning mode, i.e., first determining whether the coupling capacitance formed between the user and the touch panel changes. Then, if a touch operation is determined to exist, the accurate first touch parameters of the touch object are further determined based on the self-capacitance scanning mode of the touch panel.

[0206] In some embodiments, the number of touch objects can be determined based on the number of touch coordinates output by the touch panel in self-capacity scanning mode. If the number of touch coordinates output in self-capacity scanning mode is a single coordinate, the number of touch objects is determined to be a single coordinate. If the number of touch coordinates output in self-capacity scanning mode is at least two coordinates, the number of touch objects is determined to be at least two coordinates. A touch coordinate consists of an abscissa and a ordinate as described above.

[0207] In some embodiments, the driving module can be configured to output a first number of driving signals to drive all first electrodes and all second electrodes when the touch operation is a first type of touch operation; wherein, the driving module outputs driving signals to at least two first electrodes or at least two second electrodes at a time; the number of touch objects corresponding to the first type of touch operation is one. When the touch operation is a second type of touch operation, the driving module can output a second number of driving signals to drive all first electrodes and / or all second electrodes; the driving module outputs driving signals to one first electrode or one second electrode at a time; the number of touch objects corresponding to the second type of touch operation is at least two. The first number can be less than the second number.

[0208] In some embodiments, the first count may be less than a preset quantity, and the second count may be greater than or equal to the preset quantity. The preset quantity may be the number of the first electrode or the second electrode, or the preset quantity may be the total number of the first electrode and the second electrode.

[0209] In some embodiments, after the driving module sends a driving signal to each of the second electrodes and obtains each of the first coupling capacitors, the first coupling capacitor can be converted into a first voltage signal based on the first integrator, and then the first voltage signal can be converted into a first digital signal based on the processing module, and the change in the first coupling capacitor can be determined based on the first digital signal.

[0210] In some embodiments, after the driving module sends a driving signal to each of the first electrodes and obtains each of the second coupling capacitors, the second coupling capacitor can be converted into a second voltage signal based on the second integrator, and then the second voltage signal can be converted into a second digital signal based on the processing module, and the change in the second coupling capacitor can be determined based on the second digital signal.

[0211] In some embodiments, the processing module can determine the first touch parameters of the touch object based on the change in the first coupling capacitor and the change in the second coupling capacitor.

[0212] In some embodiments, determining a first touch parameter of a touch object based on the changes in each first coupling capacitor and / or each second coupling capacitor includes: determining an electrode pair based on the changes in each first coupling capacitor and / or each second coupling capacitor; wherein each electrode pair consists of a first electrode and a second electrode; the change in the coupling capacitor corresponding to the electrode in the electrode pair is greater than a change threshold; and determining the first touch parameter based on the intersection position of the first electrode and the second electrode in the electrode pair on the touch panel. It should be noted that a first electrode and a second electrode will only have one intersection position.

[0213] In some embodiments, when the touch operation is a first type of touch operation, an electrode pair is determined based on the changes in each first coupling capacitor and / or each second coupling capacitor; the touch position of a single touch object on the touch panel is determined based on the intersection position of the first and second electrodes in the electrode pair on the touch panel. The number of touch objects corresponding to the first type of touch operation is one.

[0214] In some embodiments, when the touch operation is a second type of touch operation, at least two electrode pairs are determined based on the changes in each first coupling capacitor and / or each second coupling capacitor; and at least two touch objects are determined on the touch panel based on the intersection positions of the first and second electrodes in each electrode pair on the touch panel. The number of touch objects corresponding to the second type of touch operation is at least two.

[0215] In this embodiment, in response to a touch operation on the touch panel, the driving module can output driving signals to the cross-arranged first and second electrodes to detect the change in coupling capacitance between the driving electrodes and the sensing electrodes and determine the first touch parameter. Furthermore, the target and / or number of times the driving module outputs driving signals differs for different types of touch operations; the number of touch targets corresponding to different types of touch operations also differs. Thus, compared to using a high-power driving method to drive each first and second electrode for all types of touch operations to detect the first touch parameter, in this embodiment, the driving module can flexibly adapt to different types of touch operations, outputting driving signals to different targets and / or outputting driving signals a different number of times. Therefore, while ensuring flexibility in touch detection, the first touch parameter can be accurately detected while reducing power consumption.

[0216] In related technologies, as touchscreens and touch-screen smartphones become increasingly popular, phone sizes are also increasing, leading to larger touchscreens, most notably the proliferation of foldable phones. However, as phone screen sizes grow larger, the power consumption of touchscreens also increases, resulting in shorter battery life and more frequent charging, negatively impacting user experience and reputation.

[0217] Based on this, this disclosure provides a touch detection method that can reduce the power consumption of touch devices. This touch detection method can dynamically switch the touch scanning mode according to the number of touch objects (e.g., the number of the user's fingers).

[0218] Based on this, in some embodiments, the driving module of the touch panel outputs driving signals in stages according to the type of touch operation, including:

[0219] When the touch operation is a first type of touch operation, the control drive module sends a drive signal to all the first electrodes at the first moment to drive all the first electrodes;

[0220] At the second moment, a drive signal is sent to all the second electrodes to drive all the second electrodes;

[0221] Among them, the number of touch objects corresponding to the first type of touch operation is a single one, which is different in the first moment and the second moment.

[0222] It should be noted that, here, since the control drive module sends drive signals to all the first electrodes at the first moment to drive all the first electrodes, and sends drive signals to all the second electrodes at the second moment to drive all the second electrodes, the drive module only needs to output drive signals twice. This reduces the drive time for driving the first and second electrodes, thus reducing the excessive power consumption caused by prolonged electrode driving and ultimately lowering power consumption.

[0223] It should be noted that, here, when the number of touch objects is single, the mode of driving all the first electrodes to scan the mutual capacitance between each of the first electrodes and each of the second electrodes, and driving all the second electrodes to scan the mutual capacitance between each of the second electrodes and each of the first electrodes, can be called the second mutual capacitance scanning mode. Here, the second mutual capacitance scanning mode can be understood as a mutual capacitance scanning mode capable of low-power scanning of the mutual capacitance between the first and second electrodes.

[0224] It should be noted that when the touch object is a finger, if the number of fingers is a single finger, the touch panel does not need to drive each first electrode and / or each second electrode individually. The touch panel does not need to perform high-power mutual capacitance scanning of each electrode in the first mutual capacitance scanning mode. The touch panel can send driving signals to all first electrodes at the first moment to drive all first electrodes; and send driving signals to all second electrodes at the second moment to drive all second electrodes, thereby performing low-power mutual capacitance scanning of each electrode in the second mutual capacitance scanning mode. Currently, the power consumption of most multi-finger mutual capacitance scanning is often 10 to 20 times that of the low-power scanning in this embodiment. Users mostly operate with a single finger. This solution proposes a finger count scanning and recognition strategy and an automatic switching strategy between high and low power mutual capacitance scanning. While ensuring multi-finger operation, it also significantly reduces the operating power of the touch chip, reduces the power consumption of the mobile device, and improves the battery life of the mobile device.

[0225] It should be noted that the low-power second mutual capacitance scanning mode in this embodiment differs from the self-capacitance scanning mode in related technologies. The self-capacitance scanning mode cannot accurately determine the touch position and has very low performance. However, the low-power second mutual capacitance scanning mode in this embodiment does not have this problem.

[0226] In some embodiments, when the touch operation is a first type of touch operation, the gating circuit in the touch panel is controlled to connect the drive module and all first electrodes at a first moment, and disconnect the drive module and all second electrodes to control the drive module to send drive signals to all first electrodes at the first moment; at a second moment, the gating circuit in the touch panel is controlled to connect the drive module and all second electrodes, and disconnect the drive module and all first electrodes to send drive signals to all second electrodes at the second moment.

[0227] In some embodiments, when the touch operation is a first type of touch operation, the driving module can be controlled to send a driving signal to all the first electrodes through the closed first switch by closing the first switch of the gating circuit and opening the second switch of the gating circuit at the first moment; the driving module can be controlled to send a driving signal to all the second electrodes through the closed second switch at the second moment by closing the second switch and opening the first switch at the second moment.

[0228] In some embodiments, when the touch operation is a first type of touch operation, the driving module can be controlled to send driving signals to all first electrodes at a first moment by closing all third switches and opening all fourth switches in the gating circuit at a first moment. All third switches can be opened and all fourth switches closed at a second moment to control the driving module to send driving signals to all second electrodes at a second moment.

[0229] For example, please see Figure 6 and Figure 7The first electrode may include RX1, RX2, RX3, RX4, and RX5 electrodes; the second electrode may include TX1, TX2, TX3, TX4, and TX5 electrodes. A third switch connected to each RX electrode can be closed at a first moment to connect all RX electrodes together. At this time, all RX electrodes act as driving electrodes to receive driving signals, and each TX electrode can act as a sensing electrode to receive signals individually within its corresponding channel. By detecting the change in coupling capacitance between each TX electrode and all RX electrodes, the location of the touch point on the touch object can be determined. Similarly, a fourth switch connected to each TX electrode can be closed at a second moment to connect all TX electrodes together. At this time, all TX electrodes act as driving electrodes to receive driving signals, and each RX electrode's corresponding channel receives signals individually. By detecting the change in coupling capacitance between each RX electrode and all TX electrodes, the location of the touch point on the touch object can be determined. Thus, the intersection position between the RX electrode where the touch point of the touch object is located and the TX electrode where the touch point of the touch object is located can be accurately determined to pinpoint the touch point of a single touch object. Here, all TX electrodes can be connected together by closing all the fourth switches for unified driving, and each RX electrode can receive the signal individually; all RX electrodes can be connected together by closing all the third switches for unified driving, and each TX electrode can receive the signal individually, thereby realizing the low-power scanning scheme in this embodiment of the present disclosure.

[0230] In some embodiments, when the touch operation is a first type of touch operation, if the first switch and the third switch are connected in series and the second switch and the fourth switch are connected in series, the first switch and all the third switches can be closed at a first moment to output a drive signal to all the first electrodes. The second switch and all the fourth switches can be closed at a second moment to output a drive signal to all the second electrodes. At the same time, the opening and closing states of the first switch and the second switch are different, and the opening and closing states of the third switch and the fourth switch are different.

[0231] In some embodiments, when the touch operation is a first type of touch operation, if the first switch and the third switch are connected in parallel, and the second switch and the fourth switch are connected in parallel, the first switch and / or all the third switches can be closed at a first moment to output a drive signal to all the first electrodes. The second switch and / or all the fourth switches can be closed at a second moment to output a drive signal to all the second electrodes. It should be noted that when driving the first electrode, the second switch and all the fourth switches are disconnected. When driving the second electrode, the first switch and all the third switches are disconnected.

[0232] In some embodiments, when the touch operation is a first type of touch operation, a target first electrode can be determined based on the changes in each first coupling capacitor; wherein, among the changes in each first coupling capacitor, the change in the first coupling capacitor corresponding to the target first electrode is the largest. A target second electrode can be determined based on the changes in each second coupling capacitor; wherein, among the changes in each second coupling capacitor, the change in the second coupling capacitor corresponding to the target second electrode is the largest. A first touch parameter of the touch object can be determined based on the intersection position of the target first electrode and the target second electrode on the touch panel; wherein, the first touch parameter is used to indicate the touch position of the touch object on the touch panel. It is understood that the target first electrode and the target second electrode here are the first electrode and the second electrode in the electrode pair described above.

[0233] In this embodiment, compared to the method of driving each first electrode column-by-column or each second electrode row-by-row at different times when there is only one touch object, in this embodiment, when there is only one touch object, the driving module outputs driving signals to all first electrodes at a first time to determine the second electrode near which the single touch object is located, and outputs driving signals to all second electrodes at a second time to determine the first electrode near which the single touch object is located. By combining the intersection of the first and second electrodes where coupling capacitance can be generated, the touch position of the touch object on the touch panel is determined. Thus, while ensuring that the specific touch position of a single touch object can be determined, the number of driving operations can be reduced, the touch reporting rate can be improved, and power consumption can be reduced.

[0234] In some embodiments, based on the type of touch operation, the driving module of the touch panel outputs driving signals in a phased manner, including:

[0235] When the touch operation is a type II touch operation, drive signals are sent sequentially to each first electrode to drive each first electrode in a time-division manner; and / or, drive signals are sent sequentially to each second electrode to drive each second electrode in a time-division manner.

[0236] Among them, the number of touch objects corresponding to the second type of touch operation is at least two.

[0237] It should be noted that, here, when there are at least two touch objects, the mode of driving each first electrode or each second electrode one by one to accurately scan the mutual capacitance between each first electrode and each second electrode can be called the first mutual capacitance scanning mode. The first mutual capacitance scanning mode can be understood as a mutual capacitance scanning mode that can sequentially perform normal power consumption scanning on the mutual capacitance between each first electrode and each second electrode.

[0238] In some embodiments, when the touch operation is a second type of touch operation, the gating circuit in the touch panel is controlled to sequentially connect the driving module and each of the first electrodes, and disconnect the driving module and all the second electrodes, so as to control the driving module to sequentially send driving signals to each of the first electrodes; and / or, the gating circuit in the touch panel is controlled to sequentially connect the driving module and each of the second electrodes, and disconnect the driving module and all the first electrodes, so as to sequentially send driving signals to each of the second electrodes.

[0239] In some embodiments, when the touch operation is a second type of touch operation, the driving module can be controlled to send driving signals to each first electrode sequentially through the closed first switch by sequentially closing the third switch of the gating circuit and opening all the fourth switches in the gating circuit; and / or, the driving module can be controlled to send driving signals to each second electrode sequentially through the closed fourth switch by sequentially closing each of the fourth switches and opening all the third switches.

[0240] For example, please see Figure 6 and Figure 7 The first electrode may include electrodes RX1, RX2, RX3, RX4, and RX5; the second electrode may include electrodes TX1, TX2, TX3, TX4, and TX5. A third switch connected to each RX electrode can be closed sequentially. In this case, each RX electrode acts as a driving electrode to receive a driving signal, and each TX electrode can act as a sensing electrode to receive a signal independently within the channel corresponding to the TX electrode. By detecting the change in coupling capacitance between each TX electrode and a single RX electrode, if the detected change in coupling capacitance is greater than a threshold, the single RX electrode acting as the driving electrode can be accurately identified as the electrode where the touch point of the touch object is located. Furthermore, by combining this with the position of the corresponding TX electrode, the positions of touch points corresponding to multiple touch objects can be accurately determined. For example, if, when RX1 acts as the driving electrode, the changes in coupling capacitance between RX1 and TX4 and TX5 both reach the threshold, the intersection between RX1 and TX4 can be determined as the position of one touch point of the touch object, and the intersection between RX1 and TX5 as the position of another touch point of the touch object.

[0241] In some embodiments, when the touch operation is a second type of touch operation, if the first switch and the third switch are connected in series and the second switch and the fourth switch are connected in series, the first switch can be closed and the second switch and all the fourth switches can be opened, and each of the third switches can be closed in sequence to output a drive signal to each of the first electrodes in sequence; and / or, the second switch can be closed and the first switch and all the third switches can be opened, and the fourth switch can be closed in sequence to output a drive signal to each of the second electrodes in sequence.

[0242] In some embodiments, when the touch operation is a second type of touch operation, if the first switch and the third switch are connected in parallel and the second switch and the fourth switch are connected in parallel, the first switch and the second switch can be turned off; by sequentially closing the third switch and turning off all the fourth switches in the gating circuit, the driving module can be controlled to send driving signals to each first electrode sequentially through the closed first switch, and / or, each fourth switch can be sequentially closed and all the third switches can be turned off, so as to control the driving module to send driving signals to each second electrode sequentially through the closed fourth switch.

[0243] In this embodiment, when there are at least two touch objects, compared to related technologies where the touch position of the touch object relative to the first electrode and the touch position relative to the second electrode are determined separately, leading to erroneous touch positions, this embodiment can accurately locate the touch position of the touch object relative to the first electrode and the second electrode by sequentially sending drive signals to each of the first electrodes and / or sequentially sending drive signals to each of the second electrodes. This ensures the accuracy of the determined touch position and the accuracy of touch reporting.

[0244] In some embodiments, before controlling the driving module of the touch panel to output driving signals sequentially based on the type of touch operation, the method further includes:

[0245] Upon detecting a touch operation, a second touch parameter of the touch object is determined; wherein the second touch parameter is used to indicate the number of touch objects;

[0246] The type of touch operation is determined based on the second touch parameter.

[0247] In some embodiments, the second touch parameter may be the same as the first touch parameter, and the second touch parameter may be used to indicate the touch position of the touch object on the touch panel. Alternatively, the second touch parameter may be different from the second touch parameter.

[0248] In some embodiments, upon detecting a touch operation, the control driving module sends a driving signal to all first electrodes at a third time to drive all first electrodes; and sends a driving signal to all second electrodes at a fourth time to drive all second electrodes; wherein the third and fourth times are different; a third coupling capacitance formed between each first electrode and the second electrode receiving the driving signal is detected, and / or a fourth coupling capacitance formed between each second electrode and the first electrode receiving the driving signal is detected; based on the change in each third coupling capacitance and / or the change in each fourth coupling capacitance, a second touch parameter of the touch object is determined; wherein the second touch parameter is used to indicate the touch position of the touch object on the touch panel, and the number of touch positions is used to determine the number of touch objects. Based on the second touch parameter, the type of touch operation is determined; if the touch operation determined based on the second touch parameter is a first type of touch operation, the second touch parameter is output, and based on the type of the first type of touch operation, the control driving module of the touch panel continues to output driving signals periodically to monitor the first touch parameter in real time. Alternatively, if the touch operation determined based on the second touch parameter is a second type of touch operation, the driving module of the touch panel continues to output driving signals in stages based on the type of the second type of touch operation to determine the first touch parameter; the second touch parameter updates the first touch parameter and outputs the first touch parameter.

[0249] Here, the type of touch operation can be accurately determined in the low-power second mutual capacitance scanning mode, thereby outputting accurate touch parameters based on the precisely determined touch operation type. This reduces power consumption during the touch operation type determination process while ensuring accurate identification, eliminating unnecessary power consumption. Ultimately, this optimizes the power consumption level of the touch module on the electronic device, reduces the operating power consumption of the touch panel, decreases power consumption of the electronic device, and improves the device's battery life.

[0250] In some embodiments, when a touch operation is detected, fingerprint recognition information for the touch object can be obtained; the second touch parameter is determined based on the number of touch objects identified in the fingerprint recognition information; and the type of touch operation is determined based on the second touch parameter.

[0251] In some embodiments, upon detecting a touch operation, the system enters any of the self-capacitive scanning modes described above. In the self-capacitive scanning mode, the change in the fifth coupling capacitance between each first electrode and the ground terminal, and the change in the sixth coupling capacitance between each second electrode and the ground terminal are determined. Based on the changes in the fifth and sixth coupling capacitances, a second touch parameter of the touch object is determined; wherein the second touch parameter indicates the touch position of the touch object on the touch panel. Based on the number of touch positions indicated by the second touch parameter, the number of touch objects is determined to be one or at least two. If the number of touch objects is one, the touch operation is determined to be a first type of touch operation; or, if the number of touch objects is at least two, the touch operation is determined to be a second type of touch operation.

[0252] In some embodiments, when the second touch parameter is a touch parameter determined in the self-capacitance scanning mode, the second touch parameter is updated based on the first touch parameter determined in the first mutual capacitance scanning mode or the second mutual capacitance scanning mode.

[0253] It should be noted that, since the self-capacitance scanning mode is unstable in detecting the touch parameters of the touch object, the self-capacitance scanning mode can be used to first determine whether the number of touch objects is one or at least two (i.e., whether the number of touch positions is one or at least two). Then, based on the accurate type of touch operation, the accurate first touch parameters of the touch object can be further determined in the first or second mutual capacitance scanning mode of the touch panel.

[0254] In this embodiment of the disclosure, when a touch operation is detected, the type of touch operation can be accurately determined based on the second touch parameter, thereby adapting to the accurate type of touch operation and precisely controlling the drive module to output drive signals according to the appropriate number of times and / or output object, so as to ensure the accuracy of the finally determined first touch parameter and the flexibility of mutual capacitance scanning for each electrode.

[0255] In some embodiments, the method further includes:

[0256] Determine if the type of touch operation has changed;

[0257] When the type of touch operation changes, the driving module of the touch panel outputs driving signals in stages based on the changed type of touch operation.

[0258] In some embodiments, it is determined in real time whether the type of touch operation has changed.

[0259] For example, it is determined whether the type of touch operation has changed based on a first touch parameter determined in real time. For instance, if the number of touch positions changes from a single to at least two based on the first touch parameter, the touch operation is determined to have changed from a first type of touch operation to a second type of touch operation; or, if the number of touch positions changes from at least two to a single based on the first touch parameter, the touch operation is determined to have changed from a second type of touch operation to a first type of touch operation.

[0260] In some embodiments, it is determined whether the type of touch operation has changed based on a predetermined period. The predetermined period can be a pre-configured period. Exemplarily, the predetermined period can be determined based on the historical frequency of changes in the type of touch operation; wherein the predetermined period and the historical frequency of changes are negatively correlated.

[0261] In this embodiment of the disclosure, since the driving module of the touch panel outputs driving signals in stages based on the changed type of touch operation when the type of touch operation is determined to change, the driving module can be timely adapted to the changed type of touch operation and output driving signals according to the appropriate output object and number of outputs.

[0262] In some embodiments, the method further includes:

[0263] When the touch operation is a type 1 touch operation, the type of touch operation is determined based on the first frequency to determine whether the type of touch operation has changed;

[0264] When the touch operation is a type 2 touch operation, the type of touch operation is determined based on the second frequency to determine whether the type of touch operation has changed;

[0265] The first frequency is greater than the second frequency.

[0266] It is understandable that when the touch operation is a type I touch operation, a low-power mutual capacitance scan is performed on each electrode. When the touch operation is a type II touch operation, a normal-power mutual capacitance scan is performed on each electrode. In this embodiment, the scanning frequency of the low-power mutual capacitance scan can be higher than the scanning frequency of the normal-power mutual capacitance scan. This allows for a rapid switch to the normal-power mutual capacitance scan mode when at least two touch objects are detected, thus ensuring that the overall touch performance is not affected.

[0267] In some embodiments, when the touch operation is a first type of touch operation, the first touch parameter can be determined by controlling the driving module to output driving signals to all first electrodes at a first moment and driving signals to all second electrodes at a second moment, based on the first frequency control module. If the number of touch positions indicated by the first touch parameter changes from a single to at least two, it is determined that the type of touch operation has changed. When the touch operation is a second type of touch operation, the first touch parameter can be determined by controlling the driving module to sequentially output driving signals to each first electrode and / or sequentially output driving signals to each second electrode, based on the second frequency control module. If the number of touch positions indicated by the first touch parameter changes from at least two to a single, it is determined that the type of touch operation has changed. Thus, while periodically detecting the first touch parameter, it is possible to accurately determine whether the type of touch operation has changed, without the need for additional monitoring methods, thereby reducing resource consumption.

[0268] In some embodiments, the first frequency may be the scanning frequency used to scan the coupling capacitance between the first electrode and the second electrode in any of the first mutual capacitance scanning modes described above in this disclosure. The second frequency may be the scanning frequency used to scan the coupling capacitance between the first electrode and the second electrode in any of the second mutual capacitance scanning modes described above in this disclosure.

[0269] In this embodiment, since the type of touch operation is determined to change from a first type of touch operation to a second type of touch operation at a relatively high frequency, it is possible to promptly determine whether the type of touch operation has changed from a first type of touch operation to a second type of touch operation. That is, it is possible to promptly determine whether the number of touch objects changes from one to at least two. At this time, it is possible to adapt to the changed number of touch objects and control the driving module to output driving signals according to appropriate output objects and frequencies to drive each first electrode and / or each second electrode to work, thereby accurately determining the touch positions corresponding to multiple touch objects. In this way, it is possible to reduce the situation where the determined touch position is interfered with due to the control module outputting driving signals not meeting the requirements, thus ensuring the accuracy of the determined touch position.

[0270] Figure 12 This is a flowchart illustrating a touch detection method according to an exemplary embodiment, such as... Figure 12 As shown, the touch detection method includes:

[0271] Step 121: When a touch operation is detected, the control drive module sends a drive signal to all the first electrodes at a first moment to drive all the first electrodes; and sends a drive signal to all the second electrodes at a second moment to drive all the second electrodes; wherein the first moment and the second moment are different.

[0272] Step 122: If the touch operation is a first type of touch operation, detect whether the type of touch operation changes from the first type of touch operation to the second type of touch operation; if the type of touch operation changes from the first type of touch operation to the second type of touch operation, then proceed to step 123; otherwise, proceed to step 121.

[0273] The first type of touch operation corresponds to a single touch object; the second type of touch operation corresponds to at least two touch objects.

[0274] Step 123: When the first type of touch operation changes to the second type of touch operation, drive signals are sent sequentially to each first electrode to drive each first electrode in a time-division manner; and / or, drive signals are sent sequentially to each second electrode to drive each second electrode in a time-division manner.

[0275] Step 124: If the touch operation is a type 2 touch operation, detect if the type of the touch operation changes from type 2 to type 1 touch operation; if the type of the touch operation changes from type 2 to type 1 touch operation, then execute step 121; otherwise, execute step 123.

[0276] Here, the touch scanning mode can be dynamically switched based on the type of touch operation (i.e., the number of touch objects, such as a user's finger). When the touch operation is a first-type touch operation, i.e., when there is only one touch object, the touch panel does not need to consume a large amount of power to sequentially perform mutual capacitance scanning on each first electrode and / or second electrode; the touch panel can perform low-power mutual capacitance scanning. When the touch operation is a second-type touch operation, i.e., when there are at least two touch objects, the touch panel can sequentially perform mutual capacitance scanning on each first electrode and / or each second electrode, switching back to the normal power consumption mutual capacitance scanning mode to accurately determine the touch positions corresponding to at least two touch objects.

[0296] When the touch operation is a type 2 touch operation, the type of touch operation is determined based on the second frequency to determine whether the type of touch operation has changed;

[0297] The first frequency is greater than the second frequency.
