Claim:
1. A touch screen apparatus comprising: a tactile touch panel comprising a plurality of touch driving lines and a plurality of touch sensing lines, wherein the tactile touch panel performs a touch function and a haptic feedback function; a touch voltage applying part which applies a touch driving voltage to the tactile touch panel; and a tactile voltage applying part which applies a tactile voltage corresponding to an image to be displayed on the tactile touch panel to at least one of the touch driving lines and the touch sensing lines of the tactile touch panel in a blanking interval, during which the touch driving voltage is not applied, when a touch on the tactile touch panel is detected based on a touch sensing signal received through the touch sensing lines, wherein a phase of the tactile voltage applied to the touch driving lines and a phase of the tactile voltage applied to the touch sensing lines are the same as each other in a state where the tactile voltage is applied to at least one of the touch driving lines and at least one of the touch sensing lines.
