<p>PURPOSE: A method and an apparatus for supplying vibration tactile are provided to form various vibration tactile patterns by operating a piezoelectric actuator based on signal attribute corresponding to a touch event generated from a touch screen. CONSTITUTION: A touch screen(110) receives a user command in a touch type and displays a graphic object. If a touch event is received from the touch screen, a driving signal generating unit(130) generates a driving signal by using a signal attribute corresponding to the touch event. An actuator controller(140) drives a piezoelectric actuator(220) and forms a vibration haptic pattern on the touch screen. The driving signal generating unit generates the driving signal.
