In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application.

Those skilled in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments without conflict.

The mobile terminal can be a mobile phone, a tablet computer, a notebook computer, a wearable device and the like. When the mobile terminal does not operate the touch screen for a period of time, the touch screen of the mobile terminal may be in a dormant state, for example, when a user watches a video played by the mobile terminal, the user usually does not touch the touch screen, and the mobile terminal may set the operating state of the touch screen to the dormant state. If the mobile terminal detects that the touch operation is performed on the touch screen within a period of time, the working state of the touch screen of the mobile terminal can be set to be an activated state.

Specifically, the working state of the touch screen of the mobile terminal includes a sleep state and an active state. The touch screen periodically triggers a scanning signal with a certain frequency to perform data scanning so as to detect the touch operation of the touch screen, for example, whether an object or a finger presses or touches the touch screen is detected. When the touch screen is in a dormant state, a small number of channels are adopted for data scanning, and if touch operation on the touch screen is detected, the working state of the touch screen can be switched from the dormant state to an activated state; under the condition of no touch operation on the touch screen, the touch screen is in a dormant state, the number of channels for data scanning is reduced, and the power consumption of the touch screen can be saved. And when the touch screen is in an activated state, all channels are adopted for data scanning so as to accurately scan data for touch operation.

However, when the touch screen is in the sleep state, because a small number of channels are used for data scanning, when a user touches or presses the touch screen, a certain time is required to detect that the touch operation is performed on the touch screen, and the sleep state is switched to the active state. Because the touch screen needs a certain time to be switched from the sleep state to the activation state with all channels, the response time of the touch screen has a certain lag, which affects the response speed of the touch screen.

In order to solve the above problems, the present application provides the following embodiments.

The present application provides a first embodiment of a control method of a touch screen, please refer to fig. 1, the method includes the following steps:

s110: a representative value for representing a tilt state of the touch screen is periodically acquired.

The method comprises the steps that a representation value used for representing the inclination state of the touch screen is periodically obtained by the touch screen in a dormant state, and generally, the change of the inclination state of the touch screen is probably caused by touch operation on the touch screen, so that whether the working state of the touch screen needs to be adjusted or not is judged according to the inclination state of the touch screen. For example, when a user uses the mobile terminal to play an electronic game, the user may frequently click or shake the mobile terminal, so that the tilt state of the touch screen of the mobile terminal changes.

The characterization value obtained for characterizing the tilt state of the touch screen may be, but is not limited to, a combination of one or more of angular velocity, acceleration, or tilt angle. For example, the characteristic value may be an angular velocity alone, or an acceleration or an inclination angle; of course, the characteristic value may also include various combinations of angular velocity, acceleration and inclination angle, for example, the characteristic value includes a combination of angular velocity and acceleration, or the characteristic value includes a combination of acceleration and inclination angle, or the characteristic value includes a combination of angular velocity, acceleration and inclination angle, etc., which is not limited in this application. There are various ways to obtain the characteristic value for characterizing the tilt state of the touch screen, for example, obtaining acceleration through an acceleration sensor, obtaining angular velocity through a gyroscope, obtaining a tilt angle through an angular velocity sensor, and the like. In addition, each of the obtained characterizing values may include a plurality of characterizing value components respectively corresponding to a plurality of directions, in this embodiment, the characterizing value components may include three characterizing value components, the directions corresponding to the three characterizing value components are perpendicular to each other, and the plurality of characterizing value components for characterizing the tilt state of the touch screen may be periodically obtained by using the multi-axis tilt state detecting device.

Taking the representation value as the angular velocity as an example, the angular velocity may be obtained by using a multi-axis gyroscope, for example, the angular velocity may be obtained by using a three-axis gyroscope, the mobile terminal may start a timer, and periodically obtain the angular velocity used for representing the tilt state of the touch screen, for example, the three-axis angular velocity is detected once every 200 milliseconds by using the three-axis gyroscope, for example, the three-axis angular velocity is detected twice every 200 milliseconds by using the three-axis gyroscope, where each angular velocity may include an angular velocity component vertical to an X axis of the mobile terminal touch screen, an angular velocity component horizontal to a Y axis of the mobile terminal touch screen, and an angular velocity component vertical to a Z axis of the mobile terminal touch screen. Specifically, when the mobile terminal is in a static state, angular velocity components of an X axis, a Y axis and a Z axis detected by the three-axis gyroscope are close to 0, and when the mobile terminal is in a state of shaking or sliding to the X axis under a horizontal screen, such as sliding to one direction of the X axis, the angular velocity component of the X axis is detected to be less than 0, and when the mobile terminal slides to the other direction of the X axis, the angular velocity component of the X axis is detected to be greater than 0. Accordingly, the tilt state of the mobile terminal can be represented by the detected change in the angular velocity. The periodic period duration and the characteristic value of the method can be set according to specific requirements, and the method is not limited herein.

S120: counting a number of times that the token value is greater than or equal to the baseline token threshold value within a first time.

After the characteristic values used for representing the inclination state of the touch screen are obtained, counting the times that the characteristic values obtained at the first time are larger than or equal to a reference characteristic threshold value, if one of the obtained plurality of characteristic values is larger than or equal to the reference characteristic threshold value, counting is performed once, if two of the obtained plurality of characteristic values are larger than or equal to the reference characteristic threshold value, counting is performed twice, and the like. Specific statistical methods are not limiting in this application.

Optionally, the number of times that the token value is continuously greater than or equal to the reference token threshold value in the first time period may be counted. For example, counting the number of times that a plurality of characterization values obtained within 3 seconds are continuously greater than or equal to a reference characterization threshold, if the characterization values greater than or equal to the reference characterization threshold are not continuous, the number of times may not be counted, so as to reduce the false triggering probability that the touch screen is switched to the active state due to the false judgment of the characterization values.

The reference characterization threshold may be an angular velocity threshold, an acceleration threshold, a tilt angle threshold, or the like, and in some examples, the reference characterization threshold may further include a plurality of combinations of thresholds, such as an angular velocity threshold and an acceleration threshold, or an acceleration threshold, and a tilt angle threshold. Taking the reference characterization threshold as an example of the angular velocity, counting the number of times that the acquired angular velocity is greater than or equal to the angular velocity threshold within the first time. Taking the reference characteristic value as the angular velocity and the acceleration as an example, the obtained times that the angular velocity and the acceleration are greater than or equal to the angular velocity threshold and the acceleration threshold in the first time are respectively counted, and of course, the angular velocity and the acceleration in different first times can also be respectively counted. The reference characterization threshold and the first time may be set according to specific situations, which is not limited in this application.

Wherein the periodic period duration is less than the first time. For example, the number of times that the characteristic value for characterizing the tilt state of the touch screen is greater than or equal to the reference characteristic threshold value within 3 seconds is counted in a manner of periodically acquiring the characteristic value for characterizing the tilt state of the touch screen every 200 milliseconds.

Optionally, referring to fig. 2, the step S120 further includes the following steps:

s1211: and judging whether the characterization value acquired in the first time is greater than or equal to a reference characterization threshold value.

Specifically, whether the plurality of characteristic value components acquired in the first time are greater than or equal to a reference characteristic threshold value is judged, and if at least one characteristic value component is greater than or equal to the reference characteristic threshold value, it is judged that the characteristic value to which the characteristic value component belongs is greater than or equal to the reference characteristic threshold value. And if the angular velocity component of any axis in the multiple axes is greater than or equal to the reference characterization threshold value, the angular velocity to which the angular velocity component belongs is considered to be greater than or equal to the reference characterization threshold value. For example, the angular velocity components of the X axis, the Y axis and the Z axis are obtained once within every 200 milliseconds by using the three-axis gyroscope, and if the angular velocity component of any one of the X axis, the Y axis and the Z axis is greater than or equal to the reference characterization threshold, if the angular velocity component of the X axis is greater than or equal to the reference characterization threshold, or the angular velocity component of the Y axis is greater than or equal to the reference characterization threshold, or the angular velocity component of the Z axis is greater than or equal to the reference characterization threshold, it is considered that the angular velocity obtained this time is greater than or equal to the reference characterization threshold.

Of course, in the detected angular velocity, there may be a negative angular velocity, and at this time, it may be determined whether the absolute values of the plurality of eigenvalue components acquired within the first time period are greater than or equal to the reference eigenvalue threshold, and if the absolute value of at least one of the eigenvalue components is greater than or equal to the reference eigenvalue threshold, it is determined that the eigenvalue to which the eigenvalue component belongs is greater than or equal to the reference eigenvalue threshold.

If the token value is greater than or equal to the reference token threshold in step S1211, step S1212 is executed, otherwise, step S1211 is continuously executed or the process is ended, which is described in this embodiment by continuously executing step S1211.

When the determination in step S1211 is no, step S1211 may be continuously performed, and a token value obtained for characterizing the tilt state of the touch screen is obtained for a new cycle in step S110, and it is continuously determined whether the token value obtained in the first time period is greater than or equal to the reference token threshold. If not, it is determined whether the token value obtained in the first time of the new round is greater than or equal to the reference token threshold value for the token value obtained periodically in the step S110. In some embodiments, the characterization value used for characterizing the tilt state of the touch screen is obtained once periodically, and step S1211 is performed to determine whether the characterization value is greater than or equal to the reference characterization threshold. This is not limited by the present application.

S1212: the number of times the statistical token value is greater than or equal to the baseline token threshold.

And if at least one characteristic value component is greater than or equal to the reference characteristic threshold value, judging that the characteristic value to which the characteristic value component belongs is greater than or equal to the reference characteristic threshold value, and adding one to the number of times that the statistical characteristic value is greater than or equal to the reference characteristic threshold value. Specifically, if the angular velocity components of the X axis, the Y axis, and the Z axis are obtained once by using the three-axis gyroscope every 200 milliseconds, and if the angular velocity components of any one of the X axis, the Y axis, and the Z axis are greater than or equal to the reference characterization threshold, the number of times that the statistical characterization value is greater than or equal to the reference characterization threshold is one. In some embodiments, if the time for determining whether the obtained token value is greater than or equal to the reference token threshold exceeds the first time in step S1211, a new round of determination is started, the number of times that the statistical token value is greater than or equal to the reference token threshold is cleared, and a new round of counting the number of times at the first time is started.

S130: and judging whether the counted times are greater than or equal to a time threshold value.

If the counted number of times is greater than or equal to the number threshold, step S140 is executed, otherwise, step S110 is executed or the process is ended, which is described in this embodiment by taking the step S110 as an example.

When the judgment in the step S130 is no, step S110 is executed, a new cycle of periodically acquiring the representation value for representing the tilt state of the touch screen is continued, and the above steps are repeated.

In some embodiments, the number threshold may be set to 1 or a natural number greater than 1. When the number threshold is 1, in the method, when it is determined in step S1211 that the token value acquired in the first time period is greater than or equal to the reference token threshold, step S140 is executed to switch the touch screen from the dormant state to the active state, that is, as long as it is determined that the token value is greater than or equal to the reference token threshold, the touch screen switches the operating state from the dormant state to the active state.

The reference characterization threshold and the number threshold of this step may be set according to requirements, for example, the reference characterization threshold and the number threshold may be determined in response to an instruction input by a user. For example, the mobile terminal touch screen may determine the baseline token threshold and the number threshold in response to a user-entered instruction regarding the baseline token threshold and the number threshold, such as the mobile terminal may provide a menu page, and the user may select or enter the baseline token threshold and the number threshold. Of course, before the mobile terminal is shipped from the factory, the reference characterization threshold and the number threshold may be configured in the system of the mobile terminal.

In addition, the historical representation values of the touch screen of the mobile terminal switched to the activated state and in the activated state can be counted, and the counted multiple historical representation values are analyzed to obtain a reference representation threshold value and a frequency threshold value. For example, a machine learning algorithm may be used to analyze a plurality of statistical historical angular velocities and learn an angular velocity threshold and a number threshold. For example, taking angular velocity as an example, counting that the touch screen is switched to the active state in one week, one month or one year, and when the touch screen is in the active state, storing the multi-axis gyroscope to obtain a historical angular velocity used for representing the inclination state of the touch screen, and simultaneously obtaining a historical reference representation threshold and a historical time threshold. And analyzing the historical angular velocity by using a machine learning algorithm to obtain a reference characterization threshold value and a frequency threshold value. Or according to the switching condition of the touch screen every week, the historical angular velocity can be respectively counted according to weekends, holidays and working days, and different reference representation threshold values and times threshold values are respectively obtained. The method for obtaining the reference characterization threshold and the number threshold is not limited.

S140: and switching the touch screen from the dormant state to the active state.

And when the counted times are greater than or equal to the time threshold value, touch operation on the touch screen possibly exists, and the touch screen is switched from the dormant state to the activated state. The number of scanning channels used by the touch screen in the active state is larger than that used in the dormant state, so that more channels are used for data scanning in the active state to detect the touch operation on the touch screen. The touch operation may be a click operation, a slide operation, or the like on the touch screen.

Specifically, when the touch screen is in the sleep state, a first number of channels may be used for data scanning, for example, a part of channels may be used for data scanning, so as to detect the touch operation of the touch screen, and detect whether the touch operation is performed on the touch screen of the mobile terminal by the user, and the power consumption of the mobile terminal may be reduced when the touch screen is in the sleep state without the touch operation. It is understood that the first number may be a number greater than or equal to zero and less than the total number of channels of the touch screen.

And when the counted times are greater than or equal to the time threshold, switching the touch screen from the dormant state to the activated state, wherein the touch screen is in the activated state, and a second number of channels can be adopted for data scanning so as to detect the touch operation of the touch screen, wherein the first number is less than the second number, and the second number is equal to or less than the number of all channels contained in the touch screen. For example, when the touch screen is in an activated state, all channels of self or mutual capacitance are adopted for data scanning so as to detect the touch operation of the touch screen.

In this embodiment, the method includes periodically obtaining a characterization value for characterizing the tilt state of the touch screen, counting the number of times that the characterization value is greater than or equal to a reference characterization threshold in a first time, if the counted number of times is greater than the number of times threshold, the touch screen may have a subsequent touch operation or other behaviors that trigger the use of the touch screen, and at this time, switching the touch screen from a sleep state to an active state, and the number of scanning channels used by the touch screen in the active state is greater than the number of scanning channels used in the sleep state, the touch screen can quickly respond to the subsequent touch operation when entering the activated state, and the response time of the touch screen is prevented from lagging when the touch operation on the touch screen is detected in the dormant state and then the touch screen is switched from the dormant state to the activated state, therefore, the time spent by the touch screen to enter the activated state can be reduced, and the response speed of the touch screen operation is improved.

With respect to the above-described embodiments, the present application also provides the following examples, which are described with the characteristic values as angular velocities, but the characteristic values of the present application are not limited to angular velocities, as described below.

The angular velocity used for representing the inclination state of the touch screen is periodically acquired by using a three-axis gyroscope with the period duration of 200 milliseconds, a reference representation threshold value is set to be 7 degrees/second, a time threshold value is set to be 4 times, and the first time is set to be 3 seconds. Judging whether the angular velocities acquired within 3 seconds are greater than or equal to a reference characterization threshold value by 7 degrees/second, if one of the angular velocity components of the X axis and the Y axis of the angular velocities or the angular velocity components of the axes is greater than or equal to 7 degrees/second, judging that the angular velocities are in a dormant state, and if the angular velocities acquired periodically reach 4 times, switching the touch screen from the dormant state to an activated state, counting the times of the angular velocities within 3 seconds which are greater than or equal to 7 degrees/second, and judging whether the counted times are greater than or equal to 4 times of the times threshold value. And if the angular velocity acquired within 3 seconds is judged to be not more than 7 degrees/second, judging the angular velocity acquired periodically in the next round.

In some application scenarios, the angular velocity used for representing the inclination state of the touch screen is acquired every 200 milliseconds with a period of 200 milliseconds, then a judgment is performed once, whether the acquired angular velocity is greater than or equal to a reference representation threshold value of 7 degrees/second or not is judged, and if the angular velocity is less than 7 degrees/second, the angular velocity obtained in the next 200 milliseconds is judged. And if the time is more than or equal to 7 degrees/second, counting the number of times of being more than or equal to 7 degrees/second of the reference representation threshold value plus 1, continuously judging the angular speed acquired next time, and if the judged time exceeds 3 seconds, clearing the number of times of being more than or equal to 7 degrees/second of the reference representation threshold value of the previous statistics, and counting the number of times of a new round. And if the number of times of the periodically acquired angular speed being greater than or equal to 7 degrees/second reaches 4 times within 3 seconds, switching the touch screen from the dormant state to the activated state.

In some application scenes, the angular speed used for representing the inclination state of the touch screen is acquired every 200 milliseconds by taking 200 milliseconds as a period, and whether the acquired angular speed is greater than or equal to 7 degrees/second is judged; if the judgment result is no, judging the angular velocity acquired next time, if the judgment result is yes, counting the number of times of being greater than or equal to 7 degrees/second of the reference characterization threshold value to be 1, judging the angular velocity acquired next time, if the judgment result is greater than or equal to 7 degrees/second, counting the number of times of being greater than or equal to 7 degrees/second of the reference characterization threshold value to be 2, and so on. If the number of times is judged to be less than 7 degrees/second, the counted number of times which is greater than or equal to the reference characterization threshold value by 7 degrees/second is cleared, and a new round of time counting is carried out. And if the counted number of times of continuously being greater than or equal to the reference characterization threshold value of 7 degrees/second reaches 4 times, switching the touch screen from the dormant state to the activated state.

Referring to fig. 3, the present application provides a second embodiment of a control method for a touch screen, including the following steps:

s210: a representative value for representing a tilt state of the touch screen is periodically acquired.

The specific implementation process of this step may refer to the specific implementation process of step S110 in the foregoing embodiment, and details are not repeated here.

S220: counting a number of times that the token value is greater than or equal to the baseline token threshold value within a first time.

The specific implementation process of this step may refer to the specific implementation process of step S120 in the foregoing embodiment, and details are not repeated herein.

S230: and judging whether the counted times are greater than or equal to a time threshold value.

If the counted number of times in step S230 is greater than or equal to the number threshold, step S240 is executed, otherwise, step S210 is executed or the process is ended, which is described in this embodiment by taking the step S210 as an example. The specific implementation process of this step may refer to the specific implementation process of step S130 in the above embodiments, and is not described herein again.

S240: and switching the touch screen from the dormant state to the active state.

The specific implementation process of this step may refer to the specific implementation process of step S240 in the foregoing embodiment, and is not described herein again.

S250: and judging whether the touch operation on the touch screen is detected in the second time.

And in the activated state, detecting the touch operation of the touch screen within the second time, and judging whether the touch operation of the touch screen is detected within the second time. The second preset time may be set according to specific requirements, which is not limited in this application.

The touch screen is a capacitive screen, and is distributed with transverse and longitudinal electrode arrays, when touch operation is carried out on the touch screen, for example, when a finger touches the touch screen, the coupling between two electrodes near a touch point is influenced, so that the capacitance between the two electrodes is changed. The touch screen can obtain the coordinate position of a touch point according to capacitance data before and after the touch acquired by scanning.

Specifically, the touch screen detects touch operation of touch by scanning data in a full channel in an activated state. When the touch screen is touched, the coordinate position of the touch point can be obtained according to capacitance data of two frames before and after the touch acquired by scanning. The data scanning is carried out by adopting the self-capacitance full channel, the self-capacitance detection is that the capacitance of each sensing unit changes, namely the change of parasitic capacitance, and the parasitic capacitance is increased when the finger touches the sensing unit, so that the existence of touch operation is judged. Adopt mutual capacitance full channel to carry out data scanning, mutual capacitance is the change that detects the mutual capacitance of ranks crossing, and mutual capacitance can reduce when having the finger touch, through the change that detects the mutual capacitance of ranks crossing, can judge whether touch operation exists. If the touch operation exists, the coordinate position of each touch point can be accurately judged.

If the touch operation on the touch screen is not detected in the second time in step S250, step S260 is executed, and if the touch operation on the touch screen is detected in the second time in step S250, the touch operation is detected, and step S270 is executed.

S260: and switching the touch screen from the active state to the dormant state.

If the touch operation on the touch screen is not detected within the second preset time, the working state of the touch screen is switched from the activated state to the dormant state, and the first number of channels are adopted for data scanning, namely, the data scanning of the whole channel is switched to a part of channels for data scanning. Under the condition of no touch operation, the mobile terminal is switched to a dormant state, so that a data scanning channel is reduced, and the power consumption of the touch screen of the mobile terminal can be reduced.

In the dormant state, data scanning detection is carried out on a part of channels to detect touch operation on touch, and if the touch operation on the touch screen is detected, the working state of the touch screen can be switched from the dormant state to the activated state so as to accurately detect the touch operation and respond to the touch operation to execute a corresponding instruction.
