Abstract
A portable electronic device includes a housing, a touch-sensitive display movable with respect to the housing, and at least one piezoelectric actuator arranged to provide tactile feedback to the touch-sensitive display in response to an actuation signal by moving the touch-sensitive display. The at least one piezoelectric actuator may move the touch-sensitive display, resulting in vibration or a single movement of the touch-sensitive display.
