The signal scanning method provided by the embodiment of the present disclosure is applied to a terminal, and referring to fig. 1, the terminal includes: a touch chip 101, a processor 102, a touch screen 103 and a housing 104. The touch screen 103 is disposed on the upper surface of the casing 104, the touch chip 101 and the processor 102 are disposed in the casing 104, and the touch chip 101 and the processor 102 can be wirelessly connected to each other.

The touch control chip 101 is used for scanning signals in a touch screen 103 of the terminal; when the signal is scanned, determining a touch event corresponding to the scanning signal at the scanning completion moment, and reporting the touch signal corresponding to the touch event to the processor 102;

the processor 102 is configured to, when receiving a touch signal sent by the touch chip 101, process the touch event according to the touch signal, so as to implement a response to the touch event.

In the related art, a scanning period of each frame is preset, and when the touch chip 101 scans a signal in a current frame scanning period, a touch event corresponding to the scanning signal is not immediately determined, but a next frame scanning period is waited to start. And determining the touch event corresponding to the scanning signal when the scanning period of the next frame starts. Moreover, after determining the touch event corresponding to the scanning signal, the touch signal corresponding to the touch event is not reported immediately, but the touch signal corresponding to the touch event is reported to the processor 102 only when the next frame scanning period starts. However, in the related art, the time interval from the scanning of the touch chip 101 to the reporting of the touch signal to the processor 102 is long, which results in a slow response speed of the processor 102 to the touch signal and a low sensitivity of the touch screen 103.

When the touch event is determined to be completed, a touch signal corresponding to the touch event is immediately reported to the processor 102. And at the moment when the scanning of the next scanning signal is finished, continuing to scan the signal of the touch screen, and simultaneously determining a touch event corresponding to the next scanning signal. When the touch event corresponding to the next scanning signal is determined to be completed, the touch signal corresponding to the touch event of the next scanning signal is immediately reported to the processor 102. In this case, the touch chip 101 performs signal scanning, determines a touch event corresponding to the scanning signal, and reports the touch signal corresponding to the touch event to the processor 102 at the fastest speed, so that the time interval from the scanning to the signal reporting of the touch signal by the touch chip 101 to the processor 102 is reduced, the response speed of the processor 102 to the touch signal is increased, and the sensitivity of the touch screen 103 is increased.

Fig. 3 is a flowchart of a signal scanning method provided in an embodiment of the present disclosure, and as shown in fig. 3, the method is applied to a touch chip in a terminal and a processor in the terminal, and includes the following steps:

in step S301, the touch chip performs signal scanning on the touch screen of the terminal to obtain a first scanning signal.

In this step, the touch chip may scan a mutual capacitance induction signal, a self-capacitance induction signal, or a noise signal when scanning the touch screen of the terminal. Therefore, the first scanning signal comprises at least one of a mutual capacitance induction signal, a self-capacitance induction signal and a noise signal; accordingly, this step may be achieved by at least one of the following steps, including:

The touch control chip scans mutual capacitance induction signals in the touch screen to obtain first scanning signals;

the touch control chip scans a self-contained induction signal in the touch screen to obtain a first scanning signal;

the touch control chip scans the noise signal in the touch screen to obtain a first scanning signal.

It should be noted that, when the touch chip performs signal scanning, a signal scanned by the touch screen during a touch operation may be used as a first scanning signal. Or, a signal between a signal scanned by the touch screen when receiving a touch operation and a signal scanned when responding to the touch operation is used as a first scanning signal, and a signal scanned after responding to the touch operation is used as a second scanning signal. Or, a signal scanned within a preset frame number of touch operation is used as a first scanning signal, and a signal scanned after the preset frame number is used as a second scanning signal. In the embodiments of the present disclosure, the first scan signal is not particularly limited. In addition, the touch chip can scan signals in the touch screen all the time, and when the user does not touch the touch screen with fingers, the touch chip cannot scan the signals, namely the touch screen does not receive touch operation; when a user touches the touch screen with a finger, the touch chip scans a signal, that is, the touch screen receives a touch operation, and at this time, the touch chip and the processor execute the signal scanning method provided by the embodiment of the disclosure.

In step S302, the touch chip determines a scanning completion time of the first scanning signal.

The first scanning signal comprises at least one of a mutual capacitance induction signal, a self-capacitance induction signal and a noise signal; accordingly, this step may be achieved by at least one of the following steps, including:

the touch control chip scans mutual capacitance induction signals in the touch screen, and determines whether the mutual capacitance induction signals are scanned in real time in the process of scanning the mutual capacitance induction signals. When the mutual capacitance induction signal is not scanned, continuing to scan; when the scanning is completed, the scanning completion time of the first scanning signal is obtained.

The touch control chip scans the self-contained inductive signal in the touch screen, and determines whether the self-contained inductive signal is scanned in real time in the process of scanning the self-contained inductive signal. When the self-capacitance induction signal is not scanned, continuing to scan; when the scanning is completed, the scanning completion time of the first scanning signal is obtained.

The touch control chip scans the noise signals in the touch screen, and determines whether the noise signals are scanned in real time in the process of scanning the noise signals. When the noise signal is not scanned, continuing to scan; when the scanning is completed, the scanning completion time of the first scanning signal is obtained.

In step S303, the touch chip continues to perform signal scanning on the touch screen at the time when the scanning of the first scanning signal is completed.

In this step, the touch chip may immediately start scanning of the next scanning signal at the time when the scanning of the first scanning signal is completed, thereby shortening the time interval between signal scanning.

In the related art, the scanning period of each frame is preset, and after the scanning of the first scanning signal is completed, the touch chip does not immediately start the scanning of the next scanning signal, but waits for the start of the scanning period of the next frame. When the next frame scanning period starts, the scanning of the next frame scanning signal is performed. The process results in a long time interval between the time when the processor receives the touch signal and the time when the touch chip completes scanning, and finally results in a slow response speed of the processor to the touch signal.

In step S304, the touch chip determines a touch event corresponding to the first scanning signal based on the scanning completion time of the first scanning signal.

In a possible implementation manner, the touch chip may immediately determine the touch event corresponding to the first scanning signal at the time when the scanning of the first scanning signal is completed, so as to improve the response speed. In another possible implementation manner, the touch chip may also wait for a first preset time period after the scanning of the first scanning signal is completed, and determine the touch event corresponding to the first scanning signal when the first preset time period is reached, so as to reduce power consumption. The first preset time period may be set and changed as needed, and is not specifically limited in the embodiment of the present disclosure.

The step of determining, by the touch chip, the touch event corresponding to the first scanning signal may be implemented by the following steps (1) to (3), including:

(1) the touch control chip extracts signal characteristics of the first scanning signal.

When the first scanning signal includes a mutual capacitance induction signal, the step may be: the touch chip can determine the signal distribution, the signal area, the signal shape, the signal amplitude and the like of the mutual capacitance induction signal, and the signal distribution, the signal area, the signal shape, the signal amplitude and the like of the mutual capacitance induction signal form the signal characteristics of the mutual capacitance induction signal.

When the first scanning signal includes a self-capacitance sensing signal, the step may be: the touch control chip determines the signal distribution, the signal area, the signal shape, the signal amplitude and the like of the self-capacitance induction signal, and the signal distribution, the signal area, the signal shape, the signal amplitude and the like of the self-capacitance induction signal form the signal characteristics of the self-capacitance induction signal.

When the first scanning signal includes a noise signal, the step may be: the touch chip determines the signal distribution, the signal area, the signal shape, the signal amplitude and the like of the noise signal, and the signal distribution, the signal area, the signal shape, the signal amplitude and the like of the noise signal form the signal characteristics of the noise signal.

(2) The touch chip determines a degree of matching between the signal characteristics and the signal characteristics of each designated touch event.

The touch chip may pre-store signal characteristics of a plurality of designated touch events, where the plurality of designated touch events may be any touch event, and this is not particularly limited in the embodiment of the present disclosure. For example, the designated touch event may be a click into an application interface, a gesture unlock, and the like.

In this step, the touch chip may determine, according to the signal characteristic of the first scanning signal, a matching degree between the signal characteristic of the first scanning signal and the signal characteristic of each of the designated touch events. For convenience of distinction, the matching degree between the signal characteristic of the first scan signal and the signal characteristic of each of the plurality of designated touch events is referred to as a first matching degree.

In one possible implementation, the touch chip may determine a second matching degree between the signal characteristic of the mutual capacitance induction signal in the first scanning signal and the signal characteristic of the mutual capacitance induction signal in each designated touch event, a third matching degree between the signal characteristic of the self-capacitance induction signal in the first scanning signal and the signal characteristic of the self-capacitance induction signal in each designated touch event, and a fourth matching degree between the signal characteristic of the noise signal and the signal characteristic of the noise signal in each designated touch event. The touch chip may perform arithmetic average or weighted summation on the second matching degree, the third matching degree, and the fourth matching degree, thereby obtaining a plurality of first matching degrees.

(3) And the touch control chip selects the touch control event corresponding to the first scanning signal from the appointed touch control events according to the matching degree between the signal characteristics and the signal characteristics of each appointed touch control event.

In this step, the touch chip may select the one with the largest first matching degree from the plurality of first matching degrees obtained in step (2), and use the designated touch event corresponding to the selected largest first matching degree as the touch event corresponding to the first scanning signal.

It should be noted that, in the related art, the touch chip does not immediately determine the touch event corresponding to the first scanning signal at the time when the scanning of the first scanning signal is completed, but waits for the start of the next frame scanning period, and determines the touch event corresponding to the first scanning signal when the next frame scanning period starts. The process results in a longer time interval between the time when the touch chip determines the touch event corresponding to the scanning signal and the time when the scanning signal is completed, and finally results in a longer time interval when the processor receives the touch signal corresponding to the touch event and a slow response speed of the processor to the touch signal. In the embodiment of the disclosure, the touch chip immediately starts to determine the touch event corresponding to the first scanning signal at the moment when the scanning of the first scanning signal is completed, so as to obtain the touch event of the first scanning signal at the fastest speed, finally, a time interval between the determination of the touch event corresponding to the first scanning signal by the touch chip and the reception of the touch signal corresponding to the touch event by the processor is shortened, and a response speed of the processor to the touch signal is increased.

In step S305, the touch chip determines a touch event completion time corresponding to the first scan signal.

the touch control chip determines whether a touch control event corresponding to a mutual capacitance induction signal in the touch screen is finished or not, and when the touch control event corresponding to the mutual capacitance induction signal is not finished, the touch control event is continuously finished; and when the touch event corresponding to the mutual capacitance induction signal is finished, obtaining the finishing moment of the touch event corresponding to the first scanning signal.

The touch control chip determines whether a touch control event corresponding to a self-contained induction signal in the touch screen is finished or not, and when the touch control event corresponding to the self-contained induction signal is not finished, the touch control event is continuously finished; and when the touch event corresponding to the self-contained sensing signal is finished, obtaining the finishing moment of the touch event corresponding to the first scanning signal.

The touch control chip determines whether a touch control event corresponding to a noise signal in the touch screen is finished or not, and when the touch control event corresponding to the noise signal is not finished, the touch control event is continuously finished; and when the touch event corresponding to the noise signal is finished, obtaining the finishing moment of the touch event corresponding to the first scanning signal.

In step S306, the touch chip reports the touch signal corresponding to the touch event to the processor based on the touch event completion time corresponding to the first scan signal.

In the embodiment of the disclosure, the touch chip may immediately report the touch signal corresponding to the touch event to the processor when determining that the touch event corresponding to the first scanning signal is completed, so as to report the touch signal corresponding to the touch event to the processor at the fastest speed, thereby shortening a time interval between the determination of the touch event corresponding to the first scanning signal by the touch chip and the reception of the touch signal corresponding to the touch event by the processor, and improving a reporting rate.

In a possible implementation manner, the touch chip may also report the touch signal corresponding to the touch event to the processor at an interval of a second preset duration after determining that the touch event corresponding to the first scanning signal is completed, so as to reduce power consumption.

The second preset time period may be set and changed as needed, and is not specifically limited in the embodiment of the present disclosure. For example, the second preset duration may be a time interval from a time when the touch event corresponding to the first scan signal is determined to be completed to a time when the scanning of the next scan signal is started. The second preset time period and the first preset time period may be the same or different, and in the embodiment of the present disclosure, this is not particularly limited.

In step S307, the processor receives a touch signal of the touch chip and processes the touch event according to the touch signal.

In a possible implementation manner, the processor receives a touch signal sent by the touch chip, where the touch signal carries touch data corresponding to a touch event, and the processor responds to a touch operation corresponding to the touch event according to the touch data corresponding to the touch event carried in the touch signal. For example, the touch operation is a game interface for entering a certain game.

In another possible implementation manner, after the touch chip determines the touch event corresponding to the first scanning signal, the touch data corresponding to the touch event may be stored in an assigned storage location in the touch chip, and then the touch signal is sent to the processor, where the touch signal carries a location identifier of the assigned storage location, the processor receives the touch signal, obtains the location identifier in the touch signal, and obtains, according to the location identifier, the touch data corresponding to the touch event from the storage location corresponding to the location identifier in the touch chip, so as to respond to the touch operation corresponding to the touch event.

It should be noted that, in a possible implementation manner, the touch chip may always perform scanning according to the steps in S301 to S306, determine the touch event corresponding to the scanning signal immediately after the scanning of the first scanning signal is completed, and report the touch signal corresponding to the touch event to the processor immediately after the touch event corresponding to the first scanning signal is determined. In the process, the signal scanning, the touch event determination and the touch signal reporting are all completed at the fastest speed, and the time interval between the signal scanning and the touch signal reporting is the minimum, so that the time interval between different touch events processed by the processor is the minimum, and the response speed is the fastest. See fig. 4. For example, the scanning signal of each frame is the first scanning signal, and it can be seen from fig. 4 that: the process has no scanning period of a frame, and the touch chip immediately starts scanning of the next first scanning signal when the scanning of the first scanning signal is finished. And immediately determining a touch event corresponding to the first scanning signal. And immediately reporting the touch signal corresponding to the touch event to a processor when the touch event corresponding to the first scanning signal is determined to be completed.

However, in the process, since signal scanning, determining of the touch event, and reporting of the touch signal are all completed at the fastest speed, the terminal can always work at a higher working frequency, the power consumption of the terminal is higher, and the working cost is higher. Therefore, in the embodiment of the present disclosure, the touch chip may be configured to execute the steps S301 to S306 in a first time period, and after the first time period is reached, the terminal is in a stable operating state because the terminal has responded to the touch operation corresponding to the touch event. At this time, when receiving the next touch operation within the second time period after the first time period, the touch chip may execute the processes of signal scanning, determining the touch event, and reporting the touch signal through any one of the following three implementation manners, so that the response speed may be reduced to a certain extent, thereby reducing the power consumption of the terminal and reducing the working cost. The first time period is a time period before the touch screen receives the touch operation, the second time period is later than the first time period, and the scanning signal obtained in the second time period is a second scanning signal. The second scanning signal may be a signal scanned in one frame scanning period, or may be a signal scanned in a plurality of frame scanning periods included in the second time period. In the embodiments of the present disclosure, this is not particularly limited.

In a first implementation manner, when the first scanning signal is a signal scanned by the touch screen within a second time period of the touch operation, the touch chip waits for the start of a first frame scanning period according to a preset each frame scanning period, where the first frame scanning period is a next frame scanning period adjacent to a current frame scanning period, and the current frame scanning period is a frame scanning period corresponding to the touch signal corresponding to the touch event reported by the touch chip to the processor. The touch control chip continuously scans signals of the touch screen at the starting moment of the first frame scanning period; waiting for the start of a second frame scanning period, wherein the second frame scanning period is the next frame scanning period which is determined according to the preset frame scanning period and is adjacent to the first frame scanning period; determining a touch event corresponding to the second scanning signal at the starting moment of the second frame scanning period; and reporting a touch signal corresponding to the touch event of the second scanning signal to the processor at the starting moment of a third frame scanning period, wherein the third frame scanning period is the next frame scanning period which is determined according to the preset frame scanning period and is adjacent to the second frame scanning period.

The specific process of this implementation can be seen in fig. 5. For example, the second scan signal is a signal scanned in a first frame scan period in the second time period, a signal scanned in a second frame scan period in the second time period may be referred to as a third scan signal, and so on. As can be seen from fig. 5: the touch control chip scans the second scanning signal in the first frame scanning period, and waits for the second frame scanning period to start after the second scanning signal is scanned. And when the scanning period of the second frame starts, determining a touch event corresponding to the second scanning signal of the first frame, and after determining that the touch event corresponding to the second scanning signal of the first frame is finished, waiting for the scanning period of the third frame to start. And reporting a touch signal corresponding to the touch event of the first frame to the processor when the scanning period of the third frame starts. Meanwhile, when the scanning period of the third frame starts, the touch event corresponding to the third scanning signal of the second frame is determined, and after the touch event corresponding to the third scanning signal of the second frame is determined to be completed, the scanning period of the fourth frame starts. And reporting a touch signal corresponding to the touch event of the second frame to the processor when the scanning period of the fourth frame starts. And scanning the signals according to the mode, determining the touch event and reporting a touch signal corresponding to the touch event to the processor.

In a second implementation manner, when the first scanning signal is a signal scanned by the touch screen within a second time period of the touch operation, the touch chip waits for the start of a first frame scanning period according to a preset frame scanning period, where the first frame scanning period is a next frame scanning period adjacent to a current frame scanning period, and the current frame scanning period is a frame scanning period corresponding to the touch signal corresponding to the touch event reported by the touch chip to the processor. The touch control chip continuously scans signals of the touch screen at the starting moment of the first frame scanning period and waits for the starting of the second frame scanning period; determining a touch event corresponding to the second scanning signal at the moment when the scanning of the second scanning signal is finished, and waiting for the start of a third frame scanning period, wherein the third frame scanning period is a next frame scanning period which is determined according to a preset frame scanning period and is adjacent to the second frame scanning period; and reporting the touch signal corresponding to the touch event of the second scanning signal to the processor at the starting moment of the scanning period of the third frame.

In the implementation manner, after the touch chip finishes scanning the second scanning signal, the touch event corresponding to the second scanning signal is immediately determined, a time gap between the second scanning completion time and the start of the second frame scanning period is reasonably utilized, sufficient time is reserved for determining the touch event corresponding to the second scanning signal, and it can be ensured that the touch event is determined to be obtained when the third frame scanning period starts, so that the touch signal corresponding to the touch event is reported to the processor. Compared with the steps S301-S306, the power consumption of the terminal is reduced to a certain extent, and the work cost is reduced.

The specific process of this implementation can be seen in fig. 6. As can be seen in fig. 6: the touch control chip scans the second scanning signal in the first frame scanning period, and waits for the second frame scanning period to start after the second scanning signal is scanned. And when the scanning of the second scanning signal is finished, immediately determining a touch event corresponding to the second scanning signal of the first frame. And after determining that the touch event corresponding to the second scanning signal of the first frame is completed, waiting for a third frame scanning period to start. And reporting a touch signal corresponding to the touch event of the first frame to the processor when the scanning period of the third frame starts. Meanwhile, a third scanning signal is scanned in the second frame scanning period, and after the third scanning signal is scanned, the third frame scanning period is waited to start. And immediately determining a touch event corresponding to the third scanning signal of the second frame after the scanning of the third scanning signal is finished. And after determining that the touch event corresponding to the third scanning signal of the second frame is completed, waiting for the scanning period of the fourth frame to start. And reporting a touch signal corresponding to the touch event of the fourth frame to the processor when the scanning period of the fourth frame starts. And scanning the signals according to the mode, determining the touch event and reporting a touch signal corresponding to the touch event to the processor.

In a third implementation manner, when the first scanning signal is a signal scanned by the touch screen within a second time period of the touch operation, the start of a first frame scanning period is waited according to a preset frame scanning period, where the first frame scanning period is a next frame scanning period adjacent to a current frame scanning period, and the current frame scanning period is a frame scanning period corresponding to a touch signal corresponding to a touch event reported by the touch chip to the processor. Determining a touch event corresponding to the second scanning signal at the moment when the scanning of the second scanning signal is finished; and reporting the touch signal corresponding to the touch event of the second scanning signal to the processor at the moment of determining the completion of the touch event corresponding to the second scanning signal.

In the implementation manner, the touch chip immediately determines a touch event corresponding to the second scanning signal at the moment when the scanning of the second scanning signal is completed; and immediately reporting the touch signal corresponding to the touch event of the second scanning signal on the processor at the moment of determining the completion of the touch event corresponding to the second scanning signal. Compared with the steps S301-S306, the power consumption of the terminal is reduced to a certain extent, and the work cost is reduced.

The specific process of this implementation can be seen in fig. 7. As can be seen in fig. 7: the touch control chip scans the second scanning signal in the first frame scanning period, and waits for the second frame scanning period to start after the second scanning signal is scanned. And when the scanning of the second scanning signal is finished, immediately determining a touch event corresponding to the second scanning signal of the first frame. And immediately reporting the touch signal corresponding to the touch event of the first frame to the processor after determining that the touch event corresponding to the second scanning signal of the first frame is finished.

And scanning the signals according to the mode, determining the touch event and reporting a touch signal corresponding to the touch event to the processor.

The first time period is a time period including a scan cycle with a specified frame number, and the number of the specified frame number may be set and changed as needed, which is not specifically limited in the embodiment of the present disclosure. For example, the specified number of frames may be 4, 5, or 6. The second time period is a time period after the first time period, and when the last frame of the first time period is a current frame, the next frame of the current frame is the first frame of the second time period.

It should be noted that, in the embodiment of the present disclosure, the touch chip may implement signal scanning, determining a touch event, and reporting a touch signal corresponding to the touch event to the processor by two different methods. The touch chip responds to the touch operation at the fastest speed through the steps S301 to S306 at the initial stage of the scanning signal. After the response, at least one of signal scanning, touch event determination and touch signal reporting corresponding to the touch event to the processor can be changed, so that the power consumption of the terminal is reduced, and the working cost is reduced. For example, when the user enters a game application and performs a touch operation on the touch screen, the user responds to the touch operation of the user entering the game application at the fastest speed by executing the above steps S301 to S306. After entering the game application, the game application can be executed according to any one of the three implementation manners. By the method, the time of the user entering the game application is shortened, the user experience is guaranteed, and the power consumption of the terminal is reduced.

In another possible implementation manner, in the embodiment of the present disclosure, it may be further configured that when the touch chip receives the touch operation, the touch chip scans according to a preset frame scanning period through the corresponding touch operation in the steps S301 to S306 when the touch operation is not received, so that power consumption of the terminal is reduced to a certain extent, and work cost is reduced.
