Greatly, so that electronic device 100 can not accurately control the display state of touch display screen 10.
For example, when proximity sensor 16 is impacted, the current bottom of proximity sensor 16 value of making an uproar may become 180, in electricity
When sub-device 100 is conversed, the signal value that proximity sensor 16 generates is 200, signal value that proximity sensor 16 generates and current
The make an uproar difference of value of bottom is 20, at this point, if close to threshold value be 100, difference 20 is less than close to threshold value 100 (20 < 100),
It may determine that proximity sensor 16 is shielded at this time, then control touch display screen 10 and be in OFF state.And under normal circumstances, it connects
The bottom of nearly sensor 16 is made an uproar be worth and do not change in the case where, proximity sensor 16 is judged as not shielded state.
So as it can be seen that when the bottom of proximity sensor 16 make an uproar value change when, the state of proximity sensor 16 may be produced
Raw erroneous judgement, can not accurately control the display state of touch display screen 10.
To sum up, the calibration method and electronic device 100 of the application embodiment is in OFF state in touch display screen 10
When multiple signal values for being generated according to proximity sensor 16 by the current bottom of proximity sensor 16 value calibration of making an uproar be initial predetermined bottom
It makes an uproar value, electronic device 100 is allowed accurately to control touch display screen according to the signal value of proximity sensor 16 in call
10 display state.

No matter influenced by what kind of, in the case where proximity sensor 16 is not blocked, the signal value of the generation of proximity sensor 16
Respectively less than 1000.
In step S142, first threshold can be set to 1000.At this point, when each signal value is respectively less than 1000, at this time
It can be determined that proximity sensor 16 is not blocked, the working as proximity sensor 16 when proximity sensor 16 is not blocked
Preceding bottom value calibration of making an uproar is that initial predetermined bottom is made an uproar value, so that the calibration of proximity sensor 16 is more accurate.
For example, 5 signal values that proximity sensor 16 is sequentially generated are respectively 210,211,212,210,213, at this point, 5
A signal value is respectively less than 1000, and the value calibration that the current bottom of proximity sensor 16 can be made an uproar is to 10.
It is appreciated that can judge that the current bottom of proximity sensor 16 is made an uproar value according to the signal value that proximity sensor 16 generates
Whether 10 are calibrated to.For example, the current bottom of proximity sensor 16 is made an uproar after value calibration, the signal value that proximity sensor 16 generates is
10, then, then it can be determined that the current bottom of proximity sensor 16 value of making an uproar has calibrated to 10.

S1421: by the multiple signal value maximum signal level and minimum signal value remove；
S1422: judging the absolute value of the difference of signal value described in any two in remaining multiple signal values is
It is no to be respectively less than second threshold；
S1423: determine that the multiple signal value is stablized when the absolute value of the difference is less than the second threshold.
In some embodiments, processor 23 is used for: by the maximum signal level and minimum letter in the multiple signal value
Number value removal；Judge whether the absolute value of the difference of signal value described in any two in remaining multiple signal values is small
In second threshold；And determine that the multiple signal value is stablized when the absolute value of the difference is less than the second threshold.
In other words, step S1421, S1422 and S1423 can be realized by processor 23.
In one example, 8 signal values that proximity sensor 16 is sequentially generated be 210,211,212,210,213,
212,208,215.Second threshold can be 10.After so removing maximum signal level 215 and minimum signal value 208, remaining 6 letters
Number value be 210,211,212,210,213,212, in remaining 6 signal values, the difference of any two signal value it is absolute
Value is less than 10, at this point it is possible to determine that 8 signal values are stable.
In this way, judging that the stable method of multiple signal values is simple and effective, avoid calculating excessively complicated.
