[0041] This embodiment provides a touch screen such as Figure 1 As shown, the touch screen 1000 may include a touch sensor 1100 , a pressure sensor 1200 , and a processing module 1300 .

[0046] <Method Example>

[0047] The present disclosure provides a pressure calibration method for a touch screen, which can be implemented by an electronic device provided with the touch screen.

[0048] Figure 2 The present invention is a flowchart of a method for calibrating pressure of a touch screen according to an embodiment of the present invention.

[0049] like Figure 2 As shown, the method includes steps S2100 to S2200 as shown below:

[0050] Step S2100: Acquire a touch signal collected by a touch sensor of the touch screen and a first pressure signal collected by a pressure sensor of the touch screen.

[0051] In this embodiment, a plurality of touch sensors and a plurality of pressure sensors may be provided in the touch screen, and the touch screen may include a plurality of detection areas, each of which may correspond to at least one pressure sensor and at least one touch sensor.

[0052] Further, any one of the touch sensors is used to collect a touch signal of a corresponding detection area in the touch screen, and any one of the pressure sensors is used to collect a first pressure signal of a corresponding detection area in the touch screen.

[0053] Furthermore, touch signals collected by a plurality of touch sensors and first pressure signals collected by a plurality of pressure sensors may be obtained.

[0054] Step S2200: calibrate the first pressure signal according to the touch signal.

[0055] In this embodiment, the first pressure signal is calibrated according to the touch signal, and for any pressure signal, the first pressure signal is calibrated according to the touch signal collected by the touch sensor corresponding to the detection area of ​​the pressure signal. That is, the touch signal used to calibrate the first pressure signal and the first pressure signal correspond to the same detection area.

[0056] In one embodiment of the present disclosure, calibrating a reference of a first pressure signal according to a touch signal includes: determining whether a target object touches the touch screen according to the touch signal; and calibrating the first pressure signal when no target object is detected touching the touch screen.

[0057] In this embodiment, the target object may be an object that can change the touch signal when touching the touch screen. For example, the target object may be a finger, a capacitive pen, or the like.

[0058] Specifically, when no target object touches the first detection area of ​​the touch screen, the corresponding touch signal may be a low level signal; when a target object touches the first detection area, the corresponding touch signal may be a high level signal. Therefore, the level of the touch signal can be used to determine whether a target object touches the first detection area. The first detection area is any detection area of ​​the touch screen.

[0059] Furthermore, the first pressure signal corresponding to the first detection area may be calibrated when no target object is detected touching the first detection area.

[0060] In one embodiment of the present disclosure, when no target object is detected touching the touch screen, the first pressure signal is calibrated, including: when no target object is detected touching the touch screen, the first pressure signal obtained when the touch signal is obtained is used as a reference pressure signal.

[0061] In this embodiment, when the pressure sensor collects the first pressure signal, it can determine the difference between the first pressure signal and the reference pressure signal as the second pressure signal, and output the second pressure signal to the processing module so that the processing module can perform gesture recognition based on the second pressure signal.

[0062] Furthermore, when no target object is detected touching the touch screen, the first pressure signal obtained when the touch signal is obtained is used as a reference pressure signal, so that the pressure sensor can output a second pressure signal indicating that the pressure value received in the corresponding detection area is zero.

[0063] In one embodiment of the present disclosure, the method further includes: in a case where it is detected that the target object touches the touch screen, stopping the calibration of the first pressure signal.

[0064] In this embodiment, when the calibration of the first pressure signal is stopped, the reference pressure signal of the pressure sensor remains unchanged and is still the first pressure signal last collected before the calibration is stopped, that is, the first pressure signal last collected before the target object is detected touching the corresponding detection area.

[0065] Through the embodiments of the present disclosure, the first pressure signal is calibrated according to the touch signal, which can avoid the influence of external environmental changes on the gesture recognition results, improve the judgment result of whether the target object performs a pressing operation on the touch screen, and dynamically determine the calibration timing of the pressure sensor based on the real-time signal of the capacitive touch sensor, and also improve the timeliness of the calibration.

[0066] In one embodiment of the present disclosure, the method also includes: obtaining a second pressure signal representing the pressure applied by the target object on the touch screen based on the reference pressure signal and the first pressure signal; in the case where it is detected that the target object touches the touch screen, detecting whether the gesture performed by the target object on the touch screen is a set gesture based on the second pressure signal; in the case where it is detected that the gesture performed by the target object on the touch screen is a set gesture, controlling the electronic device to perform an operation corresponding to the set gesture.

[0067] In this embodiment, the second pressure signal may be obtained by determining the difference between the first pressure signal and the reference pressure signal, that is, subtracting the reference pressure signal from the first pressure signal.

[0068] Since the first pressure signal obtained when the touch signal is obtained is used as the reference pressure signal in advance when the target object is not detected touching the touch screen, the reference pressure signal can be the first pressure signal collected by the pressure sensor when the target object does not touch the touch screen. Therefore, the second pressure signal obtained according to the reference pressure signal and the first pressure signal only represents the pressure applied by the target object to the corresponding detection area, eliminating the interference of the external environment on the pressure detection result, making the pressure detection result more accurate, and thus enabling more accurate gesture recognition.

[0069] In this embodiment, a set gesture corresponding to at least one control function can be set in advance according to the application scenario or specific needs. The set gesture can be, for example, any one or more of click, long press, swipe left, swipe right, swipe up, swipe down, etc.

[0070] Detecting whether the gesture performed by the target object on the touch screen is a set gesture based on the second pressure signal may include: extracting the part of the second pressure signal where the pressure is greater than or equal to a pressure threshold as a third pressure signal; and detecting the gesture performed by the target object on the touch screen based on the third pressure signal.

[0071] In this embodiment, the part of the second pressure signal where the pressure is greater than or equal to the pressure threshold indicates that the target object presses the touch screen to perform a corresponding operation gesture. Therefore, gesture recognition can be performed based on the part of the second pressure signal where the pressure is greater than or equal to the pressure threshold, that is, based on the third pressure signal.

[0072] When the duration of the third pressure signal corresponding to any detection area of ​​the touch screen is greater than or equal to the first set duration and less than or equal to the second set duration, it can be determined that the gesture performed by the user is a click.

[0073] When the duration of the third pressure signal corresponding to any detection area of ​​the touch screen is greater than the second set duration, it can be determined that the gesture performed by the user is a long press.

[0074] When a third pressure signal corresponding to at least two adjacent detection areas in the touch screen is obtained, it can be determined that the gesture performed by the user is a sliding gesture. By determining the position distribution of the at least two detection areas based on the time sequence of detecting the corresponding third pressure signals, the sliding direction of the gesture performed by the user can be determined.

[0075] The electronic device of this embodiment may be an electronic product provided with the touch screen, such as a mobile phone, a tablet computer, a smart watch, a vehicle, etc.

[0076] In this embodiment, based on the part of the second pressure signal in which the pressure is greater than or equal to the pressure threshold, detecting whether the gesture performed by the target object on the touch screen is a set gesture can make the gesture recognition result more accurate, thereby precisely controlling the electronic device on which the touch screen is set.

[0077] In one embodiment of the present disclosure, the method further includes: in a case where it is detected that the gesture performed by the target object on the touch screen is a set gesture, controlling the touch screen to provide vibration feedback.

[0078] In this embodiment, the touch screen may further include a piezoelectric ceramic vibrator, through which vibration feedback is provided.

[0079] Furthermore, when it is detected that the gesture performed by the target object on the touch screen is a setting gesture, vibration feedback can be provided to remind the user that the setting gesture is successfully executed, thereby improving the user's operating experience.
