Abstract: Provided are a haptic device providing localized haptic feedback and a controlling method thereof, wherein the haptic device includes a display, a haptic driving unit arranged on one surface of the display or inside the display, a signal controller, wherein the haptic driving unit includes a first panel, a second panel, a common electrode, and a plurality of electrode patterns, and the signal controller is configured to generate an output wave between the first panel and the second panel by outputting a voltage signal to the haptic driving unit, and provide at least one localized haptic feedback to the touch panel by controlling at least one of an amplitude and a phase of the voltage signal applied to each of the plurality of electrode patterns to overlap, reinforce, or interfere with the output wave.
