Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like 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. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating a calibration method for a touch screen according to an exemplary embodiment, where as shown in fig. 1, the method is applied to a terminal and includes the following steps:
step S101, detecting touch pressure acting on a touch screen, and detecting touch data reflecting the touch screen deformation condition when the touch pressure acts on the touch screen;
step S102, after the touch pressure is cancelled, calibrating reference data of the touch screen according to the touch data and the touch pressure; the reference data is corresponding touch data when the touch screen confirms that the touch operation is not detected.
In the embodiment of the disclosure, the pressure sensor may be used to detect the pressure on the touch screen, and obtain the touch pressure at the position where the press or the slight pressing exists. While detecting the pressure, the touch screen may detect touch data through the touch sensor, where the type of the touch data is determined by a 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 type touch sensor is pressure value data.
Taking the capacitive touch sensor as an example, when a touch pressure exists on the touch screen, the touch screen may slightly deform, which causes a capacitance value of the touch sensor detected by the capacitance to change, and further changes the capacitance value based on a touch operation on the surface of the touch screen. After the touch pressure is removed, slight deformation still exists on the touch screen. Because the capacitance structure of the touch sensor is slightly changed, the touch sensor can still detect touch data after touch pressure is removed.
If the area acted by the touch pressure is not calibrated, the touch screen is detected wrongly, and touch data are still reported when no touch operation is performed. For example, in the area where the touch pressure acts, the touch operation is still reported after the touch pressure is cancelled, resulting in an erroneous operation. Therefore, in the embodiment of the present disclosure, after the touch pressure is removed, the reference data of the touch screen is calibrated according to the touch data detected by the touch sensor based on the position of the touch pressure. During calibration, calibration can be performed only for the area on which the touch pressure acts, and calibration can also be performed on the whole touch screen.
It is understood that, since the deformation caused by the touch pressure may be recovered in a period of time, the process of calibrating the reference data of the touch screen may also last for a period of time in the embodiment of the present disclosure. For example, touch data of a position on which touch pressure acts is continuously monitored within a few seconds after touch pressure is removed, and since the touch data may change along with deformation recovery in this time, calibration may be performed by using the touch data in the deformation recovery process. In this way, false detection due to deformation can be reduced during this period of calibration. After the deformation is recovered, the touch data at this time also corresponds to the recovered capacitance value, so that the reference data of the touch screen is recovered after the calibration.
Therefore, false detection of the touch screen after the touch pressure disappears can be reduced, so that the touch screen can still accurately detect touch operation when slight deformation occurs in slight extrusion or collision and the like, and the use experience of a user is further improved.
In some embodiments, as shown in fig. 2, the method further comprises:
step S201, determining a deformation coefficient of the touch screen according to the touch data and the touch pressure;
in 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, including:
step S202, determining a touch position according to the touch data;
and step S203, after the touch pressure is cancelled, adjusting the reference data of the touch position according to the deformation coefficient.
In the embodiment of the disclosure, the deformation caused by the touch pressure and the deformation coefficient of the touch data can be determined according to the relationship between the touch data and the touch pressure, and the deformation coefficient represents the deformation of the touch screen under the action of the pressure. Since the deformation generated by the touch pressure still exists after the touch pressure is cancelled, the reference data of the position acted by the touch pressure 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 of the touch operation which is not reported.
Here, the deformation coefficient includes a ratio between the touch pressure and the touch data. Because in a certain range, the touch pressure and the deformation of the touch screen are positively correlated, and further the touch pressure and the touch data are positively correlated, the deformation coefficient can be determined according to the ratio of the touch pressure to the touch data. When the reference data of the touch position is adjusted, the reference data can be adjusted by a corresponding proportion according to the deformation coefficient, and further calibration is achieved.
Here, since the touch sensor of the touch screen carries the coordinates of the touch position when detecting the touch data, the touch data can be used to determine the position where the touch pressure acts, i.e., the touch position. After the touch pressure is removed, calibration is performed for the position.
It should be noted that, in the time period when the touch pressure acts, because the touch pressure may be generated by the touch operation of the user, the touch screen needs to report the coordinates of the corresponding touch position according to the touch data as the detected touch operation. And then executing a corresponding touch instruction based on the touch operation, for example, clicking a control at the touch position.
After the touch pressure is cancelled, because the pressure sensor cannot detect the pressure at this time, it can be determined that the touch data detected in the area acted by the touch pressure at this time is the change of capacitance caused by slight deformation of the touch screen due to the touch pressure. Therefore, here, after the touch pressure is removed, the area on which the touch pressure acts is calibrated using the above-described deformation coefficient, and the reference value in the area is adjusted, thereby eliminating the influence of the deformation from the adjustment of the data.
In some embodiments, the method further comprises:
determining whether the deformation coefficient is within a pre-stored deformation coefficient range;
after the touch pressure is cancelled, adjusting the reference data of the touch position according to the deformation coefficient and the touch position, including:
and if the deformation coefficient is within the deformation coefficient range, adjusting the reference data of the touch position according to the deformation coefficient after the touch pressure is cancelled.
Here, the deformation coefficient range may be obtained through experiments before the terminal leaves a factory, for example, the touch data and the touch pressure are in a range of a linear relationship, or a range in which touch deformation caused by the touch pressure is recoverable.
In the embodiment of the present disclosure, since there is a certain corresponding relationship between the deformation on the touch screen and the touch data within a certain range, the calibration may be directly performed according to the deformation coefficient, and if the deformation generated on the touch screen is too large, the influence on the touch data exceeds the corresponding relationship within the above range, and at this time, the calibration using the deformation coefficient may be inaccurate.
Therefore, in the embodiment of the present disclosure, it may be determined whether the deformation coefficient corresponding to the touch pressure is within a predetermined range. If within the predetermined range, the deformation coefficient can be used for calibration. In an embodiment, since there is a corresponding relationship between the touch pressure and the deformation coefficient, it can be directly determined whether the touch pressure value is within a predetermined pressure range, and if the touch pressure value is within the predetermined pressure range, it indicates that the deformation coefficient is within the predetermined deformation coefficient range. At this time, the corresponding deformation coefficient is determined, and the area acted by the touch pressure is calibrated. Since the touch area can be calibrated only by using the deformation coefficient, the calibration can be completed quickly by a small amount of calculation.
In addition, when the deformation coefficient is within the deformation coefficient range, the deformation caused by the touch pressure can be recovered after a period of time. Therefore, the calibration of the reference data of the touch position may last for a predetermined time period, and the calibration is performed within the predetermined time period by using the deformation coefficient corresponding to the detected touch data and the touch pressure until the deformation is recovered. Therefore, false touch alarm or touch failure before slight deformation caused by touch pressure is not recovered can be reduced.
In some embodiments, the method further comprises:
and if the deformation coefficient is out of the deformation coefficient range, adjusting all reference data of the touch screen according to touch data detected by a touch sensor on the touch screen after the touch pressure is cancelled.
With respect to the above embodiment, 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 not be changed continuously with the change of the touch pressure. That is, at this time, the deformation coefficient cannot accurately represent 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.
At this time, the original calibration procedure can be used to scan and forcibly calibrate the full-screen touch sensor of the touch screen, without considering the area acted by the touch pressure and the size of the touch pressure. And the result of the calibration is forced to be the final calibration result, so that the unrecoverable deformation caused by the touch pressure is compensated. Therefore, the accuracy of the overall detection of the touch screen can be improved, and accurate touch data can be detected under the condition that the touch screen is deformed.
In some embodiments, the determining a deformation coefficient of the touch screen according to the touch data and the touch pressure includes:
determining a relation curve of touch pressure and touch data in a time period when the touch pressure on the touch screen is detected;
and determining the deformation coefficient according to the change rate of the relation curve.
In an embodiment of the disclosure, the deformation coefficient may be determined by using a change rate of a relationship curve between a touch pressure value and corresponding touch data in a time period when the touch pressure is detected. Compared with the touch data generated by recorded touch pressure and deformation after touch pressure is cancelled, the more accurate deformation coefficient can be obtained, and therefore calibration of the action range of the touch pressure is achieved.
The disclosed embodiments also provide the following examples:
when a user puts a terminal device with a touch screen in a bag or a pocket, the surface of the touch screen is easily squeezed or collided by other objects to generate slight deformation. After the deformation, the data processing of the terminal device may generate an abnormality, such as a touch failure or a touch false alarm.
In the embodiment of the disclosure, data are compensated by using a software algorithm, and data abnormity caused by physical deformation is compensated. The data compensation can be processed by using a deformation coefficient, and the deformation coefficient can be obtained by using the pressure value and the corresponding touch data. The processing flow is shown in fig. 3, and comprises the following steps:
step S301, detecting touch pressure by using a pressure sensor, and sensing the moment when the touch pressure is cancelled;
step S302, continuously reporting touch data in the process of detecting the touch pressure;
step S303, storing the pressure value of the touch pressure in a register at the moment when the touch pressure is cancelled;
step S304, judging whether the touch pressure is in a preset range;
here, the pressure value F of the touch pressure is K × Δ data, where K is a deformation coefficient and is data (0% to 100%) which dynamically changes, and Δ data is touch data, such as a capacitance variation of the touch capacitor. The pressure sensor detects the lifting of the finger and transmits the pressure value to the register. And determining whether the pressure value belongs to a preset range or not by utilizing a relation curve library of the pressure value, the preset pressure value and the touch data. And if the pressure value belongs to the preset range, calibrating according to the deformation coefficient corresponding to the pressure value until the deformation of the touch screen is recovered to be normal. If the pressure value is no longer within the predetermined range, a forced calibration is performed after the finger is lifted. And if the pressure sensor detects that the finger is not lifted, continuously detecting the pressure value and reporting the coordinate corresponding to the touch data.
Step S305, if the touch pressure is in a preset range, detecting a change value of the touch data;
step S306, calibrating reference data based on the touch pressure and the deformation coefficient determined by the touch data;
and step S307, if the touch pressure is not in the preset range, forcibly calibrating the touch screen.
According to the technical scheme of the embodiment of the disclosure, the software algorithm is used for compensating the touch detection abnormity caused by physical deformation, and the use experience of a user is improved.
