Abstract: A method of controlling a stylus pen of a touch panel includes steps of: outputting an uplink control signal to a sensing electrode of the touch panel for controlling the stylus pen in an uplink control period; and outputting a direct-current (DC) voltage to a gate line of the touch panel in the uplink control period.
