METHOD OF DRIVING TOUCH SCREEN DISPLAY APPARATUS, MEDIUM FOR RECORDING METHOD, AND TOUCH SCREEN DISPLAY APPARATUS
First Claim
1. A method of driving a touch screen display apparatus comprising a touch detector for detecting a touch by an object and a panel comprising a photo sensor unit for capturing an image of the object and a light emitting unit for realizing an image to be displayed, the method comprising:
- generating an input signal in response to the touch by the object with the touch detector;
converting the input signal into an output signal having a plurality of enable periods and at least one disable period;
updating, during the at least one disable period of the output signal, a noise determination reference of a sensing signal provided from the photo sensor unit; and
removing, during an enable period of the enable periods, noise from the sensing signal according to the updated noise determination reference.
