Embodiment four
The present embodiment and embodiment one, embodiment two and embodiment three are distinctive in that the possibility of the original value proportional shifting touching test point further contemplating capacitance touch screen, the original value offset type touching test point by applying the mode of pressure repetitive measurement to determine, in order to improve the validity and reliability of correction further.Below based on embodiment one, capacitance touch screen bearing calibration in the embodiment of the present invention is described, certainly, on the basis of the embodiment of the present invention, embodiment two technical characteristic newly-increased relative to embodiment one or embodiment two technical characteristic newly-increased relative to embodiment one can also be increased.As shown in Figure 4, the capacitance touch screen bearing calibration in the embodiment of the present invention includes:
Step 401, acquisition do not execute the original value touching test point that stressed capacitance touch screen reports;
Specifically, the description of the step 101 that step 401 is referred in embodiment illustrated in fig. 1, repeat no more herein.
If the original value of the above-mentioned touch test point of this acquisition of step 402 in default recoverable deviation range, then applies the pressure of a known dimensions relative to the side-play amount of reference value for above-mentioned capacitance touch screen surfaces;
It should be noted that, when performing step 402 every time, it is likely to different for above-mentioned capacitance touch screen surfaces pressure applied size, optionally, preset one group of pressure size and number, in order to being that above-mentioned capacitance touch screen surfaces applies correspondingly sized pressure according to the number of times that performs of step 402.Illustrate, preset one group of pressure size and number, when i & lt performs step 402 (wherein, i is the natural number more than 0), it is default known dimensions and the pressure being numbered i for above-mentioned capacitance touch screen surfaces pressure applied, when i+1, it is default known dimensions and the pressure being numbered i+1 for above-mentioned capacitance touch screen surfaces pressure applied.Certainly, the embodiment of the present invention can also apply for above-mentioned capacitance touch screen surfaces the pressure of a known dimensions otherwise, be not construed as limiting herein.
Step 403, acquisition have executed the original value of stressed above-mentioned touch test point;
After step 402, trigger above-mentioned capacitance touch screen and report the original value executing stressed above-mentioned touch test point, in order to obtain the original value having executed this touch test point stressed in step 403.
Owing to the original value of the above-mentioned touch test point of this acquisition is to acquire after applying pressure for capacitance touch screen, therefore, the original value of this touch test point of this acquisition should have the difference in size of this pressure applied relative to the original value of this touch test point when not applying pressure.
Step 404, the original value executing stressed above-mentioned touch test point, the last original value not executing stressed above-mentioned touch test point obtained and the above-mentioned qualified deviation range that obtain according to the last time generate correction function;
In the embodiment of the present invention, the original value offset type that the original value executing stressed above-mentioned touch test point obtained according to the last time and the last original value not executing stressed above-mentioned touch test point obtained substantially can determine that this touch test point is constant offset or proportional shifting.nullSuch as,Remember that being equivalent to reference value with the corresponding side-play amount applying pressure size sum according to the calculated the last original value executing stressed above-mentioned touch test point obtained of constant offset is side-play amount A、The side-play amount that the last original value not executing stressed above-mentioned touch test point obtained is equivalent to reference value is side-play amount B,If now side-play amount A is equal to side-play amount B,Then can determine that the original value offset type of this touch test point is constant offset,And constant offset amount is namely equal to side-play amount A,Therefore in step 404,Can according to the original value executing stressed above-mentioned touch test point of the last time acquisition、The last original value not executing stressed above-mentioned touch test point obtained and above-mentioned qualified deviation range generate correction function x=x '-(d-d '),Make value that the original value not executing stressed above-mentioned touch test point of the last acquisition obtains after the correction function of this generation processes relative to the side-play amount of said reference reference value in this qualified deviation range,Wherein,X represents the original value that calibrated function processed,X ' represents the original value processed without correction function,D represents constant offset amount,With the d any value with symbol in the desirable above-mentioned qualified deviation range of d '.nullIf the side-play amount A calculated according to constant offset is bigger with side-play amount B difference,Then it is believed that the original value offset type of this touch test point is proportional shifting,Such as,If reference value is 1600,The last pressure being applied with 200 electric capacity for this capacitance touch screen surfaces,The original value 1575 of this touch test point obtained,The last original value not executing this touch test point stressed obtained is 1400,The side-play amount A then calculated according to constant offset is-225,Side-play amount B is-200,There is the error of 25 in side-play amount A and side-play amount B,If proportionally offseting calculation,It is 1575/ (1600+200) that the last original value executing stressed above-mentioned touch test point obtained is equivalent to reference value with the corresponding side-play amount applying pressure size sum、The side-play amount that the last original value not executing stressed above-mentioned touch test point obtained is equivalent to reference value is side-play amount is 1400/1600,Owing to 1575/ (1600+200) is equal to 1400/1600,Therefore think that the original value offset type of this touch test point is proportional shifting,And be 14/16 than row coefficient.Therefore in step 404, can according to the original value executing stressed above-mentioned touch test point of the last time acquisition, the last original value not executing stressed above-mentioned touch test point obtained and above-mentioned qualified deviation range generate correction function x=16*x '/14, make value that the original value not executing stressed above-mentioned touch test point of the last acquisition obtains after the correction function of this generation processes relative to the side-play amount of said reference reference value in this qualified deviation range, wherein, x represents the original value that calibrated function processed, x ' represents the original value processed without correction function.
