S150. whether the condition adjudgement current state according to touch event is correcting state.If current state is correction
State, then into step S12.Specifically, needed for touch screen to be adjusted to correcting state before touch screen is corrected, can
Whether it is preset state with the thermodynamic state verification current state according to touch event, for example, it can be determined that during the holding of touch event
It is long whether to exceed preset duration, if exceeding preset duration, judge that current state is correcting state；Or judge touch event
Whether the number of times occurred in preset time period exceeds preset times, if exceeding preset times, judges that current state is school
Positive status；Or judge whether the pressure that touch event is produced on the touchscreen is more than preset pressure, when more than preset pressure
Judge that current state is correcting state.Or before being corrected can be continuous touch-control state for the first time, for example, the shape that dispatches from the factory
State.Do not processed if current state is not correcting state.
