Static elimination method for a touch screen
Abstract:
The present invention relates to A static eliminating method for a touch screen comprising: detecting if the touch screen departs from an object by using said photo sensor, and counting the number of communication failures between the touch screen and a control chip or detecting if the touch screen of a hand-held device is switched from the state of facing down into the state of facing up by using a gravity sensor, counting the number of failures of communication between the touch screen and the control chip; executing the reset operation of turning off and then turning on if the number of failures exceeds a communication failure set value; or executing the reset operation of resetting the register software of the touch screen/turning off and then turning on touch screen if the number of failures is smaller than a communication failure set value and the number of touch events in the same area of the touch screen in a set time exceeds a false report set value.(executing the reset operation of resetting the register software of the touch screen in a preferable embodiment) By using this method, the touch screen can be quickly reset to recover normal service if the touch screen is affected by static.
