For convenience of understanding of technical solutions of the embodiments of the present application, the following description is provided for related technologies of the embodiments of the present application, and the following related technologies may be arbitrarily combined with the technical solutions of the embodiments of the present application as alternatives, which all belong to the protection scope of the embodiments of the present application.

The touch screen is used as an important human-computer interaction channel and is used as an important device in a mobile phone and handheld equipment, the basic principle of the touch screen is capacitance sensing, when a finger or an object of a human body contacts a sensing material on the surface of the touch screen, capacitance change can be caused, and therefore the number of the fingers or the objects pressed on the surface of the touch screen at present can be obtained.

The working principle of the touch screen is as follows: and triggering a scanning signal with a certain frequency at fixed time, detecting whether an object comprises a finger and is pressed on the surface of a touch screen of the terminal equipment, calculating a coordinate according to the capacitance signal and reporting.

Taking a capacitive touch screen as an example, the principle of identifying an object by the capacitive touch screen is as follows: judging whether an object reports the state of the object after touching the touch screen by utilizing a capacitance induction principle of the touch screen, wherein the touch mainly refers to the state that a finger touches the object and the like; the states are mainly classified into a state of pressing, lifting, and moving after pressing.

By utilizing the capacitance sensing principle of the touch screen, the touch screen can identify the coordinates of the object by calculating the capacitance difference between the touch screen and the non-touch screen contacted with the current object, finding out the peak value difference value of the area by calculating the area of the capacitance difference, and judging whether the area is within a certain preset reporting threshold value, so that the reporting coordinates are sent from the terminal equipment.

The capacitive touch screen mainly comprises a transmitting channel and a receiving channel, wherein the acquired capacitance data of the transmitting channel and the receiving channel to the ground is self-capacitance data (the judgment of other auxiliary functions except state judgment, such as a proximity induction function, waterproof judgment and the like, is realized through the self-capacitance data), and the acquired data of the transmitting channel and the receiving channel is mutual capacitance data (the states of pressing, lifting, moving after pressing and the like of a finger are judged through the mutual capacitance data).

The classification of the capacitive screen sensing type is described in detail as follows:

1. mutual capacitance

One axis is driven by a set of Alternating Current (AC) signals, and the response across the touch screen is sensed by electrodes on the other axis, called cross-over sensing, because the electric field is transferred in a cross-over fashion from one electrode group (e.g., rows) to another electrode group (e.g., columns) through the dielectric layer of the upper panel, as shown in fig. 1, with the sending and receiving ends of the mutual capacitance being different and crossing vertically.

It should be noted that ITO (ITO is a transparent conductive material) can be used to make the horizontal electrodes and the vertical electrodes, which is different from the capacitor in that the crossing place of the two sets of electrodes will form a capacitor, i.e. the two sets of electrodes respectively constitute two poles of the capacitor. When a finger touches the capacitive screen, the coupling between the two electrodes near the touch point is affected, thereby changing the capacitance between the two electrodes. When the mutual capacitance is detected, the transverse electrodes sequentially send out excitation signals, and the longitudinal electrodes simultaneously receive signals, so that the capacitance value of the intersection point of the transverse electrodes and the longitudinal electrodes, namely the capacitance value of the two-dimensional plane of the whole touch screen can be obtained.

As for the structural wiring of mutual capacitance, a double-layer stacking scheme, a single-layer bridging scheme, a single-layer multi-point scheme or an ultrathin double-layer scheme can be adopted, wherein in the double-layer stacking scheme, the distance between a transmitting end (TX) and a receiving end (RX) can be set to be more than 150 micrometers, the suspension effect is good, and the influence of dripping water is small; in the single-layer bridging scheme or the single-layer multipoint scheme, the distance between TX and RX is small, the suspension effect is poor, and the influence of dripping is large; in the scheme of the ultrathin double layer, the distance between TX and RX can be set to be about 50um, the suspension effect is poor, and the water dripping influence is large.

2. Self-capacitance

Both the horizontal and vertical electrodes are driven by a single-ended sensing method, i.e. the driving circuits of one row and one column are the same, called single-ended sensing, as shown in fig. 2, the sending and receiving ends of the self-capacitance are the same.

It should be noted that the horizontal and vertical electrode arrays are made of ITO on the glass surface, and form capacitors with the ground respectively. When a finger touches the capacitive screen, the capacitance of the finger is superposed on the capacitance of the screen body, so that the capacitance of the screen body is increased.

For the structural wiring of the self-capacitance, a scheme of independently sampling in the horizontal axis (X) direction and the vertical axis (Y) direction, a scheme of a triangle, and a scheme of an include can be adopted, wherein the scheme of independently sampling in the X direction and the Y (vertical axis) direction needs the number of channels to be X + Y, and only single-point gesture adding can be supported; with the triangular scheme, a single layer of wiring with the number of channels Y × 2 (or X × 2) is required, which is low cost, and some schemes can support multi-point division, as shown in fig. 3. The scheme of using the cell mostly adopts a checkered pattern, needs the number of channels to be X X Y, can support multiple fingers, and supports better light transmittance, thinner and narrow frame design.

Compared with mutual capacitance, the self-capacitance characteristic adopts full channels to send signals simultaneously mostly, and the single channel is sampled in sequence, and because the influence of no ground wire in the center of the screen body, the effect is better in waterproof and anti-common mode interference (like terminal equipment), and the mutual capacitance characteristic needs X + Y channels to obtain X Y data, can support multi-point operation, and is waterproof and anti-common mode interference ratio from the electric capacity.

Based on the principle and various structures of above-mentioned touch-sensitive screen, can realize diversified screen, and along with the popularization of folding screen, because partial capacitance flexible screen shows that the interference is great, the flexible screen structure of electric capacity itself leads to anti-interference relatively poor, and the interference noise is great under the mode of charging, the mistake appears a little the condition easily, and the probability of wrong report is very high.

According to an embodiment of the present application, a driving method for switching a mode of a terminal device is provided, and fig. 4 is a flowchart illustrating the driving method for switching the mode of the terminal device according to the embodiment of the present application, where the method may be applied to a touch screen of the terminal device, for example, the touch screen may be disposed on an electronic device (such as a terminal or a tablet) or other processing devices in a single-machine, multi-machine or cluster system, and may implement processing logic of the touch screen driving method. The terminal may be a User Equipment (UE), a mobile device, a Personal Digital Assistant (PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, or the like. In some possible implementations, the method may also be implemented by a processor calling computer readable instructions stored in a memory. As shown in fig. 4, the flow of the driving method for switching the terminal device mode includes:

s401, receiving a first instruction, wherein the first instruction is used for representing whether the touch screen is driven to enter an Active mode in a charging state.

In some examples, the first instruction may be obtained according to state information, where the state information is that the terminal device is in a charging state, and the first instruction is to drive the touch screen to enter an Active mode; the state information is that the first instruction is to drive the touch screen to close an Active mode under the condition that the terminal device is in a non-charging state.

In some examples, after the touch screen is driven to enter the Active mode in the charging state, the Active mode may be maintained in the charging state, instead of being switched to another mode, such as an Idle (Idle) mode or a Sleep (Sleep) mode, unlike the related art in which the Active mode is switched to another mode for a duration lasting several seconds or several minutes after being entered, so as to avoid that the mode switching in the charging mode affects the response accuracy of the touch operation, thereby reducing the probability of false alarm of the touch screen.

S402, responding to the first instruction, and driving a hardware system of the touch screen to execute mode switching operation corresponding to the first instruction.

In some examples, when the first instruction is to drive the touch screen to enter the Active mode, after driving a hardware system of the touch screen, the hardware system of the touch screen may force the touch screen to enter the Active mode; the first instruction is to drive the touch screen to close the entered Active mode, and after the hardware system of the touch screen is driven, the hardware system of the touch screen can force the touch screen to close the Active mode.

By adopting the method and the device, a first instruction (the first instruction is used for representing whether the touch screen is driven to enter the activation mode in the charging state) can be received, so that the hardware system of the touch screen can be driven to execute the mode switching operation corresponding to the first instruction in response to the first instruction, and the probability of false alarm of the touch screen in the charging mode is reduced.

It should be noted that, when the touch screen is used in the charging state, false alarm is likely to occur, the touch screen system may be operated in the present application to drive the touch screen and finally implement mode switching (corresponding mode switching operation executed corresponding to different first instructions), and mainly aims at switching control of a dynamic Active mode of the touch screen. The normal mode may be a switch between the Active mode and the Idle mode or the Sleep mode according to whether a finger touches or not. In other words, the touch screen is driven by a specific first instruction, and then mode switching can be realized, so that the false alarm probability is reduced.

In one possible implementation manner, in response to the first instruction, a hardware system that drives the touch screen executes a mode switching operation corresponding to the first instruction, including: the first instruction is to drive the touch screen to enter the Active mode, and immediately switch from the current mode to the Active mode.

In one possible implementation manner, in response to the first instruction, a hardware system that drives the touch screen executes a mode switching operation corresponding to the first instruction, including: when the first instruction is used for driving the touch screen to enter the Active mode, recording a data mark to be switched to the Active mode (namely, recording that the first instruction is received through the data mark, and immediately executing a mode switching operation corresponding to the first instruction after a preset condition is met), and switching from the current mode (the sleep mode or the Idle mode) to the Active mode according to the data mark to be switched to the Active mode when the preset condition is met (such as a screen-off event aiming at the touch screen in the sleep mode or a screen-on event aiming at the touch screen in the Idle mode for a period of time).

In one possible implementation manner, in response to the first instruction, a hardware system that drives the touch screen performs a mode switching operation corresponding to the first instruction, including: and under the condition that the first instruction is used for driving the touch screen to close the Active mode, indicating the touch screen to enter a normal mode (the normal mode comprises the step of determining whether to continuously switch among the Active mode, the Idle mode and the Sleep mode according to whether touch operation exists on the touch screen by fingers).

Some examples of the operation modes of the touch screen include the Active mode, the Idle mode, and the Sleep mode. Wherein, the Active mode of the touch screen is as follows: the touch screen triggers a self-capacitance/mutual capacitance scanning signal, and simultaneously collects self-capacitance/mutual capacitance data to calculate coordinates. In response to the touch event, the duty cycle is greater than the Idle mode; the Idle mode of the touch screen is as follows: and triggering a self-contained scanning signal by the touch screen, and simultaneously acquiring self-contained data to calculate the self-contained data. No response to the touch event at this time; the sleep mode of the touch screen is as follows: the touch screen is in a sleep mode when scanning is stopped, the TP IC does not trigger the coding waveform, the sleep low-power-consumption state is entered, and at the moment, the touch event is not responded.

As shown in fig. 5, the switching logic among the Active mode, the Idle mode and the Sleep mode of the touch screen includes the following contents:

1) Active mode to Idle mode switching: and when the surface of the touch screen is not touched, switching to an Idle mode under the condition that the preset time and the preset threshold are reached.

2) Idle mode to Active mode switching: and when the surface of the touch screen is touched, switching to an Active mode under the condition that a preset threshold value is reached.

After the TP IC is reset, the mode of Active is directly entered.

3) Idle mode to Sleep mode switching: and when the touch screen is turned off, sending a Sleep name and switching to a Sleep mode.

4) Switching from Active mode to sleep mode: and when the touch screen is turned off, sending a Sleep name and switching to a Sleep mode.

5) Sleep mode to Active mode switching: after the TP IC is reset, the mode of Active is directly entered.

According to an embodiment of the present application, a driving method for switching a mode of a terminal device is provided, and fig. 6 is a flowchart illustrating the driving method for switching the mode of the terminal device according to the embodiment of the present application, where the method may be applied to a terminal device, for example, the touch screen may be disposed on an electronic device (such as a terminal or a tablet) or other processing devices in a single-machine, multi-machine or cluster system, and may implement a processing logic of a control method for driving the touch screen. The terminal may be a User Equipment (UE), a mobile device, a Personal Digital Assistant (PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, or the like. In some possible implementations, the method may also be implemented by a processor calling computer readable instructions stored in a memory. As shown in fig. 6, the flow of the driving method for switching the terminal device mode includes:

s601, monitoring the state of the terminal equipment in an interruption mode to obtain state information.

S602, obtaining a first instruction according to the state information, wherein the first instruction is used for representing whether the touch screen is driven to enter an Active mode in a charging state.

S603, responding to the first instruction, and driving a hardware system of the touch screen to execute mode switching operation corresponding to the first instruction.

In some examples, when the state information indicates that the terminal device is in a charging state, the first instruction is to drive the touch screen to enter an Active mode; the state information is that the first instruction is to drive the touch screen to close an Active mode under the condition that the terminal device is in a non-charging state.

In some examples, in the case that the first instruction is to drive the touch screen into the Active mode, after the touch screen is driven into the Active mode in the charging state, the Active mode may be maintained in the charging state, instead of being switched to another mode, such as an Idle (Idle) mode or a Sleep (Sleep) mode, which is different from that in the related art, the Active mode is switched to another mode for a duration of several seconds or several minutes after the touch screen enters the Active mode, so that the influence of the mode switching in the charging mode on the response accuracy of the touch operation is avoided, and the probability of false alarm of the touch screen is reduced.

In some examples, when the first instruction is to drive the touch screen to enter the Active mode, a data flag to be switched to the Active mode is recorded (that is, the data flag records that the first instruction has been received, and a mode switching operation corresponding to the first instruction is executed immediately after a preset condition is met), and when the preset condition is met (for example, a screen-off event for the touch screen in a sleep mode or a screen-on event for the touch screen in an Idle mode without contact for a period of time), the current mode (the sleep mode or the Idle mode) may be switched to the Active mode according to the data flag to be switched to the Active mode.

In some examples, in addition to the above-mentioned forcing the touch screen to enter the Active mode in the charging mode, the touch screen may be forced to close the Active mode in the non-charging mode to recover to the normal mode, that is, to switch the mode among the Active mode, the sleep mode and the Idle mode.

By adopting the method and the device, the state of the terminal equipment can be monitored in an interruption mode to obtain the state information, the first instruction is responded after the first instruction is obtained according to the state information, the hardware system of the touch screen is driven to execute the mode switching operation corresponding to the first instruction, and the probability of false alarm of the touch screen in the charging mode is reduced.

It should be noted that the terminal device includes a touch screen, and in the process of performing instruction interaction between the terminal device and the touch screen, the terminal device sends a first instruction to the touch screen, or specifically, a system service related to battery management is run in the terminal device to send the first instruction to the touch screen system, so as to implement instruction interaction.

The touch screen is used in a charging state, false alarm is easy to occur, the touch screen system can be operated after responding to a first instruction in the application to drive the touch screen and finally realize mode switching (corresponding mode switching operation executed by corresponding different first instructions), the switching control of a dynamic Active mode of the touch screen is mainly aimed at, specifically, after the touch screen drive receives the corresponding first instruction, the instruction is given to a hardware system of the touch screen to execute a forced entering Active mode (or keep the forced entering Active mode) or a normal mode. The normal mode may be a switching mode in which the active mode, the Idle mode, and the Sleep mode are maintained according to whether a finger touches or not. In other words, the touch screen is driven by a specific first instruction, and then mode switching can be realized, so that the false alarm probability is reduced.

In a possible implementation manner, monitoring the state of the terminal device in an interrupted manner to obtain state information includes: determining the state information as that the terminal equipment is in a charging state under the condition that a charging port of the terminal equipment detects an interrupt event inserted into the terminal equipment; and under the condition that the charging port of the terminal device detects an interrupt event of pulling out the terminal device, determining that the state information is that the terminal device is in a non-charging state. Wherein, the port of this terminal equipment includes: any one of a USB port or a Type C port.

In an application example shown in fig. 7, performing mode switching includes the following steps:

s701, running system services related to battery management in the terminal equipment, and monitoring the state of the terminal equipment in an interrupt mode.

S702, judging the state of the terminal equipment according to the current detected state to obtain state information.

In some examples, whether the terminal device is in a charging state (corresponding to two different state information) can be monitored, and in the process of judging the state of the terminal device, if the terminal device is in the charging state, the touch screen hardware system can be subsequently set to enter an Active mode all the time, so that the anti-interference performance is improved, the speed of recognizing noise is improved, the probability of a touch screen randomly reporting point is reduced, and the user experience is improved; if the terminal equipment is in a non-charging state, a touch screen hardware system can be subsequently set to keep switching among an active mode, an Idle mode and a Sleep mode according to whether the finger touches or not.

In some examples, the state of the terminal device is monitored by an interrupt manner, for example, regarding the charging state of the terminal device, a charger is inserted into a charging port of the terminal device, an interrupt event inserted into the terminal device is detected through a USB port or a Type C port, and the voltage and the current of the terminal device are obtained, so that it is determined that the terminal device is in the charging state; regarding the non-charging state of the terminal device, the charger is pulled out from the charging port of the terminal device, and the USB port or the Type C port detects an interrupt event of pulling out the terminal device, so that the terminal device is determined to be in the non-charging state.

S703, the related system service of battery management obtains a first instruction according to the state information to send the first instruction to the touch screen, so as to inform the touch screen to drive a hardware system of the touch screen. If the state information is that the terminal equipment is in the charging state, setting a first instruction as an instruction for driving the touch screen to enter an Active mode, and sending the first instruction to the touch screen.

In some examples, the state of the current terminal device may be further recorded, that is, a data flag to be switched to the Active mode is recorded (that is, a first instruction "an instruction to drive the touch screen to enter the Active mode" or "an instruction to force the touch screen to enter the Active mode" is recorded through the data flag, and a mode switching operation corresponding to the first instruction is executed immediately after a preset condition is met), and when the preset condition is met (for example, a screen-off event for the touch screen in a sleep mode or a screen-on event for a period of time without contact and entering the touch screen in an Idle mode), the current terminal device may be switched to the Active mode according to the data flag to be switched to the Active mode. In other words, in the case of inserting the terminal device, in addition to immediately switching to the Active mode in response to the first instruction, optionally, after the touch screen is turned off or turned on, switching to the Active mode from the current mode (sleep mode or Idle mode) in response to the first instruction, and keeping the Active mode all the time.

Because the frequency interval of Idle mode scanning is larger than that of Acvtive scanning, the first instruction is responded, so that the Idle mode is always entered or kept not to exit, and the time influence of switching the Idle mode to the Active mode is reduced, for example, in experimental data, the Idle mode scanning is 80Hz, and the Acvtive mode scanning is 120Hz, so that the noise identification speed is increased, the anti-interference performance is improved, and the false alarm probability is reduced.

And S704, obtaining a first instruction according to the state information by the relevant system service of the battery management so as to send the first instruction to the touch screen, thereby informing the touch screen of driving a hardware system of the touch screen. If the state information is that the terminal equipment is in a non-charging state, setting a first instruction as an instruction for driving the touch screen to close an Active mode, and sending the first instruction to the touch screen.

S705, the touch screen receives the corresponding first instruction, and issues an open instruction or a close instruction to the touch screen hardware system (specifically, if the touch screen driving system receives the first instruction, the open instruction or the close instruction is sent to the touch screen hardware system).

In some examples, the touch screen driving system receives a corresponding first instruction, and accordingly, sets an opening instruction or a closing instruction to the touch screen hardware system. The android system is divided into different software levels; the related system service of battery management can be responsible for monitoring whether the terminal equipment is in a non-charging state or not so as to judge whether a function of forcibly entering in a charging mode and keeping an Active mode all the time needs to be started or not, and the touch screen driving system is responsible for receiving the first instruction issued by the upper system service and carrying out data communication with a hardware device touch device, namely a touch screen hardware system.

And S706, after the touch screen hardware system receives the opening instruction or the closing instruction, setting a register of the touch screen hardware system through an interface.

In some examples, the touch screen hardware system receives an open command or a close command, and the register of the touch screen hardware system is set through the interface (which may be set through an I2C interface, an SPI interface, or an I3C interface). The register may be a memory of a touch screen hardware system, a CPU and a memory of the touch screen hardware system may also be provided in the touch screen hardware system, and data operation such as register may also be performed.

S707, the touch screen hardware system switches the touch screen to a forced Active mode according to the opening instruction; or the touch screen hardware system switches the touch screen to a normal mode switching state according to the closing instruction.

By adopting the application example, after the terminal equipment is inserted, the probability of misinformation is improved because the noise interference caused by the terminal equipment can cause the capacitive data of the touch screen to cause probabilistic misinformation due to the noise interference.

It should be noted that the above examples may combine various possibilities in the embodiments of the present application, and details are not described here.

In a possible implementation manner, the driving unit 801 is configured to instruct the touch screen to enter the normal mode if the first instruction is to drive the touch screen to close the Active mode.
