[0049] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0050] Figure 1 is a flow chart of a touch screen calibration method according to an exemplary embodiment. Figure 1As shown, the method is applied to a terminal and comprises the following steps:

[0051] Step S101, detecting touch pressure acting on the touch screen, and detecting touch data reflecting a deformation condition of the touch screen when the touch pressure acts on the touch screen;

[0052] Step S102: after the touch pressure is cancelled, calibrate the reference data of the touch screen according to the touch data and the touch pressure; wherein the reference data is the touch data corresponding to when the touch screen confirms that no touch operation is detected.

[0053] In the embodiments of the present disclosure, the pressure on the touch screen can be detected by a pressure sensor to obtain the touch pressure at the location where the pressure is pressed or slightly squeezed. While detecting the pressure, the touch screen can detect touch data through the touch sensor. The type of touch data is determined by the detection principle of the touch sensor. For example, the touch data detected by the capacitive touch sensor is capacitance value data. The touch data detected by the pressure touch sensor is pressure value data.

[0054] Taking a capacitive touch sensor as an example, when there is touch pressure on the touch screen, the touch screen will produce a slight deformation, causing the capacitance value of the touch sensor detected by the capacitance to change, and the touch operation based on the surface of the touch screen will further cause the capacitance value to change. After the touch pressure is removed, there is still a slight deformation on the touch screen. Since the capacitance structure of the touch sensor has changed slightly, the touch sensor can still detect touch data after the touch pressure is removed.

[0055] If the area where the touch pressure acts is not calibrated, the touch screen will be incorrectly detected, and touch data will still be reported when there is no touch operation. For example, in the area where the touch pressure acts, the touch operation is still reported after the touch pressure is cancelled, resulting in erroneous operation. Therefore, in the embodiment of the present disclosure, after the touch pressure is cancelled, the baseline data of the touch screen is calibrated according to the touch data detected by the touch sensor based on the location of the touch pressure. When calibrating, calibration can be performed only on the area where the touch pressure acts, or the entire touch screen can be calibrated.

[0056] It is understandable that since the deformation caused by the touch pressure may recover within a period of time, in the embodiment of the present disclosure, the process of calibrating the baseline data of the touch screen may also last for a period of time. For example, the touch data of the position where the touch pressure acts is continuously monitored within a few seconds after the touch pressure is released. Since the touch data may change with the recovery of the deformation during this period of time, the touch data can be used for calibration during the process of deformation recovery. In this way, during this period of calibration, false detection caused by deformation can be reduced. After the deformation is recovered, since the touch data at this time also corresponds to the restored capacitance value, the baseline data of the touch screen is finally restored after calibration.

[0057] In this way, the false detection of the touch screen after the touch pressure disappears can be reduced, so that the touch screen can still accurately detect the touch operation when it is slightly squeezed or collided and slightly deformed, thereby improving the user experience.

[0058] In some embodiments, Figure 2 As shown, the method also includes:

[0059] Step S201, determining a deformation coefficient of the touch screen according to the touch data and the touch pressure;

[0060] In the above step S102, after the touch pressure is cancelled, calibrating the reference data of the touch screen according to the touch data and the touch pressure includes:

[0061] Step S202: determining a touch position according to the touch data;

[0062] Step S203: After the touch pressure is cancelled, adjust the reference data of the touch position according to the deformation coefficient.

[0063] In the disclosed embodiment, the deformation caused by the touch pressure and the deformation coefficient of the touch data can be determined based on the relationship between the touch data and the touch pressure, and the deformation coefficient reflects the deformation of the touch screen under the pressure. Since the deformation caused by the touch pressure still exists after the touch pressure is cancelled, the reference data of the position where the touch pressure acts can be adjusted according to the deformation coefficient. After the touch pressure is cancelled, the touch data of the position detected by the touch screen corresponds to the reference data that does not report the touch operation.

[0064] Here, the deformation coefficient includes the ratio between the touch pressure and the touch data. Since within a certain range, the touch pressure is positively correlated with the deformation of the touch screen, and thus the touch pressure and the touch data are positively correlated, the deformation coefficient can be determined based on the ratio between the touch pressure and the touch data. When adjusting the reference data of the touch position, the reference data can be adjusted to a corresponding ratio based on the deformation coefficient, thereby achieving calibration.

[0065] Here, since the touch sensor of the touch screen carries the coordinates of the touch position when detecting touch data, the touch data can be used to determine the position where the touch pressure acts, that is, the above-mentioned touch position. After the touch pressure is removed, calibration is performed for the position.

[0066] It should be noted that during the period of touch pressure, since the touch pressure may be generated by the user's touch operation, the touch screen needs to report the coordinates of the corresponding touch position according to the touch data as the detected touch operation. Then, the corresponding touch command is executed based on the touch operation, for example, clicking the control at the touch position.

[0067] After the touch pressure is cancelled, since the pressure sensor cannot detect the pressure at this time, it can be determined that the touch data detected in the area where the touch pressure is applied is the change in capacitance caused by the slight deformation of the touch screen caused by the touch pressure. Therefore, here, after the touch pressure is cancelled, the deformation coefficient is used to calibrate the area where the touch pressure is applied, and the reference value in the area is adjusted, thereby eliminating the influence of the deformation from the data adjustment.

[0068] In some embodiments, the method further comprises:

[0069] Determining whether the deformation coefficient is within a pre-stored deformation coefficient range;

[0070] After the touch pressure is cancelled, adjusting the reference data of the touch position according to the deformation coefficient and the touch position includes:

[0071] If the deformation coefficient is within the deformation coefficient range, then after the touch pressure is cancelled, the reference data of the touch position is adjusted according to the deformation coefficient.

[0072] Here, the deformation coefficient range can be obtained through experiments before the terminal leaves the factory, for example, within the range of a linear relationship between touch data and touch pressure, or within the range of a recoverable touch deformation caused by touch pressure.

[0073] In the embodiment of the present disclosure, since there is a certain correspondence between the deformation on the touch screen and the touch data within a certain range, calibration can be directly performed according to the above-mentioned deformation coefficient. However, if the deformation generated on the touch screen is too large, the impact on the touch data has exceeded the correspondence within the above-mentioned range. At this time, calibration using the deformation coefficient may be inaccurate.

[0074] Therefore, in the embodiments of the present disclosure, it is possible to first determine whether the deformation coefficient corresponding to the touch pressure is within a predetermined range. If it is within the predetermined range, the deformation coefficient can be used for calibration. In one embodiment, since there is a corresponding relationship between the touch pressure and the deformation coefficient, it is possible to directly determine whether the touch pressure value is within the predetermined pressure range. If the touch pressure value is within the predetermined pressure range, it means that the above deformation coefficient is within the predetermined deformation coefficient range. At this time, the corresponding deformation coefficient is determined, and the area where the touch pressure acts is calibrated. Since only the touch area can be calibrated using the deformation coefficient, the calibration can be completed quickly with a small amount of calculation.

[0075] In addition, since the deformation caused by the touch pressure can be restored after a period of time when the deformation coefficient is within the above deformation coefficient range, the calibration of the reference data of the touch position can be continued for a predetermined time, and the deformation coefficient corresponding to the detected touch data and the touch pressure is used for calibration within the predetermined time until the deformation is restored. In this way, the touch false alarm or touch failure before the slight deformation caused by the touch pressure is restored can be reduced.

[0076] In some embodiments, the method further comprises:

[0077] If the deformation coefficient is outside the deformation coefficient range, then after the touch pressure is canceled, all the reference data of the touch screen are adjusted according to the touch data detected by the touch sensor on the touch screen.

[0078] Compared with the above embodiments, when the touch pressure is not within the predetermined pressure range or the deformation coefficient is not within the predetermined deformation coefficient range, the touch data may no longer continue to change with the change of the touch pressure. In other words, at this time, the deformation coefficient can no longer accurately reflect the accurate relationship between the deformation caused by the touch pressure and the touch data, and therefore, the deformation coefficient cannot be used for calibration.

[0079] At this time, the original calibration procedure can be used to scan and force calibration of the touch screen's full-screen touch sensor, without considering the area where the touch pressure acts and the size of the touch pressure. In addition, the result of the forced calibration is the final calibration result, thereby compensating for the irreversible deformation caused by the touch pressure. In this way, the accuracy of the overall touch screen detection can be improved, and accurate touch data can still be detected when the touch screen is deformed.

[0080] In some embodiments, determining the deformation coefficient of the touch screen according to the touch data and the touch pressure includes:

[0081] Determining a relationship curve between the touch pressure and the touch data during a period of time when the touch pressure on the touch screen is detected;

[0082] The deformation coefficient is determined according to the rate of change of the relationship curve.

[0083] In the disclosed embodiment, the deformation coefficient can be determined by using the change rate of the relationship curve between the touch pressure value and the corresponding touch data during the period of time when the touch pressure is detected. Compared with the touch data generated by using the recorded touch pressure and deformation after the touch pressure is cancelled, a more accurate deformation coefficient can be obtained, thereby realizing the calibration of the touch pressure action range.

[0084] The present disclosure also provides the following examples:

[0085] When a user puts a terminal device with a touch screen in a bag or pocket, the surface of the touch screen is easily squeezed or collided with other objects to cause slight deformation. After the deformation, the data processing of the terminal device may be abnormal, such as touch failure or touch false alarm.

[0086] In the disclosed embodiment, a software algorithm is used to compensate the data to make up for the data anomaly caused by physical deformation. The data compensation can be processed using the deformation coefficient, which can be obtained through the pressure value and the corresponding touch data. Figure 3 As shown, the following steps are included:

[0087] Step S301, using a pressure sensor to detect touch pressure, and sensing the moment when the touch pressure is cancelled;

[0088] Step S302: During the process of detecting the touch pressure, continuously reporting the touch data;

[0089] Step S303, storing the pressure value of the touch pressure in a register at the moment when the touch pressure is cancelled;

[0090] Step S304, determining whether the touch pressure is within a predetermined range;

[0091] Here, the pressure value of the touch pressure F = K*△data, where K is the deformation coefficient, which is a dynamically changing data (0% to 100%), and △data is the touch data, such as the change in the capacitance value of the touch capacitor. The pressure sensor detects that the finger is lifted and transmits the pressure value to the register. The relationship curve library between the pressure value, the predetermined pressure value and the touch data is used to determine whether the pressure value belongs to the predetermined range. If the pressure value belongs to the predetermined range, calibration is performed according to the deformation coefficient corresponding to the pressure value until the deformation of the touch screen returns to normal. If the pressure value is no longer within the predetermined range, forced calibration is performed after the finger is lifted. If the pressure sensor detects that the finger is not lifted, the pressure value continues to be detected and the coordinates corresponding to the touch data are reported.

[0092] Step S305: if the touch pressure is within a predetermined range, detecting a change value of the touch data;

[0093] Step S306, calibrating the reference data based on the touch pressure and the deformation coefficient determined by the touch data;

[0094] Step S307: If the touch pressure is no longer within the predetermined range, the touch screen is forcibly calibrated.

[0095] Through the technical solution of the embodiment of the present disclosure, a software algorithm is used to compensate for the touch detection anomaly caused by physical deformation, thereby improving the user experience.
