TOUCH RAW DATA CORRECTION METHOD AND TOUCH SCREEN DEVICE USING THE SAME

摘要

The present invention relates to a method for correcting touch raw data and a touch screen device using the same. The method for correcting the touch raw data according to an embodiment of the present invention comprises (a) a step for offering driving pulses to the Tx lines of a touch screen panel and outputting the touch raw data by converting the voltage of touch sensors received through Rx lines into digital data; (b) a step for detecting a specific data pattern by analyzing the touch raw data; (c) a step for generating second reference data by converting first reference data which is original reference data when the specific data pattern is detected and correcting the touch raw data by using the second reference data; and (d) a step for correcting the touch raw data by using the first reference data when the specific data pattern is not detected.
