Sign.As shown in figure 4, the capacitance touch screen bearing calibration in the embodiment of the present invention includes:
Step 401, acquisition do not apply the original value for the touch detection point that stressed capacitance touch screen reports；
Specifically, step 401 is referred to the description of the step 101 in embodiment illustrated in fig. 1, and details are not described herein again.
If the original value of step 402, this above-mentioned touch detection point obtained exists relative to the offset of reference value
In preset recoverable deviation range, then apply the pressure of a known dimensions for above-mentioned capacitance touch screen surfaces；
It should be noted that being above-mentioned capacitance touch screen surfaces pressure applied size when executing step 402 every time
May be different, optionally, presets one group of pressure size and give and number, so as to according to the execution number of step 402
Apply pressure of corresponding size for above-mentioned capacitance touch screen surfaces.It is compiled for example, presetting one group of pressure size and giving
Number, (wherein, i is the natural number greater than 0), the pressure applied by above-mentioned capacitance touch screen surfaces when i-th executes step 402
The pressure that power is preset known dimensions and number is i is above-mentioned capacitance touch screen surfaces pressure applied in i+1
For preset known dimensions and number the pressure for being i+1.It certainly, can also otherwise be above-mentioned in the embodiment of the present invention
Capacitance touch screen surfaces apply the pressure of a known dimensions, are not construed as limiting herein.
Step 403, acquisition have applied the original value of stressed above-mentioned touch detection point；
After step 402, it triggers above-mentioned capacitance touch screen and reports and applied the original of stressed above-mentioned touch detection point
Value, to obtain the original value for having applied the stressed touch detection point in step 403.
Since the original value of this above-mentioned touch detection point obtained is obtained after applying pressure for capacitance touch screen
Obtain, therefore, this obtain the touch detection point original value relative to when not applying pressure the touch detection point it is original
Value should have the difference in size of this pressure applied.
Step 404, the original value for having applied stressed above-mentioned touch detection point according to the last time acquisition, the last time
The original value for not applying stressed above-mentioned touch detection point and above-mentioned qualified deviation range obtained generates correction function；
In the embodiment of the present invention, according to the last time obtain the original value for having applied stressed above-mentioned touch detection point and
The original value for not applying stressed above-mentioned touch detection point that the last time obtains substantially can determine the original of the touch detection point
Value offset type is constant offset or proportional shifting.For example, what note was obtained according to the last time that constant offset is calculated
The original value for having applied stressed above-mentioned touch detection point is equivalent to reference value and applies the inclined of the sum of pressure size with corresponding
Shifting amount is offset A, the last original value for not applying stressed above-mentioned touch detection point obtained is equivalent to reference
The offset of value is offset B, if offset A is equal to offset B at this time, can determine the original value offset of the touch detection point
Type is constant offset, and constant offset amount is equal to offset A, therefore in step 404, it can be obtained according to the last time
Apply the original value of stressed above-mentioned touch detection point, the original for not applying stressed above-mentioned touch detection point of the last acquisition
Initial value and above-mentioned qualified deviation range generate correction function x=x '-(d-d '), so that the last acquisition does not apply pressure
Above-mentioned touch detection point the correction function processing that is generated through this of original value after obtained value referred to relative to said reference

The processed original value of positive function, d indicate constant offset amount, d ' can use in above-mentioned qualified deviation range and d with symbol any
Value.If larger according to the counted offset A of constant offset and offset B difference, it is believed that the original value of the touch detection point
Offset type is proportional shifting, for example, setting reference value as 1600, the last time is that the capacitance touch screen surfaces are applied with
The pressure of 200 capacitors, the original value 1575 of the touch detection point of acquisition, what the last time obtained does not apply the stressed touch
The original value of test point is 1400, then is -225 according to the counted offset A of constant offset, offset B is -200, offset A
There are 25 errors with offset B, if proportionally offset is calculated, what the last time obtained has applied stressed above-mentioned touch detection
It is 1575/ (1600+200), most that the original value of point, which is equivalent to reference value and the corresponding offset for applying the sum of pressure size,
The original value for not applying stressed above-mentioned touch detection point closely once obtained is equivalent to the offset of reference value as offset
Amount is 1400/1600, since 1575/ (1600+200) is equal to 1400/1600, therefore thinks the original value offset of the touch detection point
Type is proportional shifting, and is 14/16 than column coefficient.Therefore in step 404, the application pressure that can be obtained according to the last time
The original value of above-mentioned touch detection point, the last original value for not applying stressed above-mentioned touch detection point obtained and
Above-mentioned qualification deviation range generates correction function x=16*x '/14, so that stressed above-mentioned touching is not applied in the last acquisition
Offset of the value obtained after touching the correction function processing that the original value of test point is generated through this relative to said reference reference value
Amount is in the qualification deviation range, wherein x indicates that the calibrated processed original value of function, x ' indicate at without correction function
The original value managed.
Certainly, which is also possible to not only have constant offset but also there are proportional shiftings, then optionally, difference root
According to formula y0=kx0+ b and y1=kx1+ b calculates k and b, and generates correction function: x=kx '+b according to the k and b being calculated,
