Force snesor refer to using it is to be calibrated for the center of circle, using pre-determined distance as the pressure sensing below the touch-screen in the circular scope of radius
Device.Wherein, pre-determined distance rule of thumb data can be configured, and predetermined threshold value rule of thumb data can also be configured.
The processor of electronic equipment can be with the pressure sensor and the metal knot of electronic equipment in be calibrated pre-determined distance of detecting distance
Whether the capacitance between component occurs the change more than predetermined threshold value, specifically, pressure sensor is with fixed frequency detecting
Its capacitance between hardware is simultaneously sent to processor, and processor is received and stored.When processor receive away from
After the capacitance sent from the pressure sensor in be calibrated pre-determined distance, contrasted with the capacitance of its last moment,
If both differences are more than predetermined threshold value, then it is assumed that pressure sensor and metal structure in be calibrated pre-determined distance
Capacitance between part generates the change more than predetermined threshold value.Whether detection electronic equipment specifically may be used in the second horizontal level
To be detected by acceleration transducer.
It should be noted that the second horizontal level is electronic equipment be in touch-screen place down and with plane-parallel,
Rear shell place upward and with the position of plane-parallel.
When the metal for detecting pressure sensor and electronic equipment on electronic equipment in be calibrated pre-determined distance of distance
Change more than predetermined threshold value occurs for the capacitance between structural member, and detects that electronic equipment is in the second horizontal level, this
When, it is equivalent to put on point to be calibrated with the weight of electronic equipment, detects all pressure sensors and electricity of electronic equipment
Capacitance between the hardware of sub- equipment, calibration capacitance value is determined according to capacitance.Here all pressure sensors
Including the pressure sensor in be calibrated pre-determined distance.Now, electronic equipment detects all pressures by pressure sensor
Capacitance between force snesor and hardware can obtain multiple capacitances.Optionally, electronic equipment can be detected only
Once, using detect one group of multiple capacitance as calibration capacitance value；It can also detect repeatedly, obtain multigroup capacitance, will
Correspond and average in multigroup capacitance group, obtain one group of multiple condenser paper average, these average values are defined as
Calibration capacitance value.The present embodiment is without limitation.
S103：Offset data after calibration is determined according to the weight of calibration capacitance value and electronic equipment.
Specifically, can be using the weight of calibration capacitance value and electronic equipment as calibration after calibration capacitance value is determined
The input of algorithm determines the offset data after calibration according to calibration algorithm.Calibration algorithm can use existing calibration algorithm, its
Here is omitted for realization principle.Offset data after calibration can mend when user is using touch-screen to the pressure of user
Repay, to ensure that user uses the precision of touch-screen, solve because the shell during user's use due to electronic equipment occurs
Touch-screen false triggering or it the failure such as can not trigger caused by deformation.The weight of electronic equipment is defaulted in electronic equipment
's.
Touch screen calibration method provided in an embodiment of the present invention, if detecting, electronic equipment is in first level position,
The touch screen display point to be calibrated of electronic equipment, point to be calibrated be used to prompt user using point to be calibrated as the strong point so that
Electronic equipment is horizontal, if detecting the pressure sensor and electricity on electronic equipment in be calibrated pre-determined distance of distance
