A METHOD FOR ELIMINATING NOISE USING SCAN DIRECTION SWITCHING IN A ELECTROSTATIC CAPACITY TYPE TOUCH PANEL

摘要

PURPOSE: A noise removing method by scanning direction switching of an electrostatic capacitive touch panel is provided to efficiently remove noise which generates on the same row or the same column by converting a scanning direction. CONSTITUTION: Electrostatic capacitive is measured by scanning to a first scanning direction(S100). The electrostatic capacity is measured by scanning to a second scanning direction which crosses with the first scanning direction(S200). The scanning direction is switched into the second scanning direction(S300). Predetermined filtering is applied to the measured electrostatic capacity.
