Claim:
A mobile terminal, comprising: a terminal body including a display module; a touch sensor disposed to overlap the display module and configured to be touch sensitive; haptic modules mounted at the body; and a controller configured to feed a current to at least one of the haptic modules when the touch sensor senses a first touch input, wherein each haptic module comprises: a chamber covered by a flexible membrane; and an actuating module accommodated in the chamber and configured to press the flexible membrane based on an energy conversion of the current such that the flexible membrane is expanded, wherein first visible information associated with the first touch input is displayed on the display module in response to the first touch input, wherein a protrusion of the haptic modules is protruded in response to the first touch input, the protrusion of the haptic modules mirroring the first visible information displayed on the display module, wherein the haptic modules are configured to detect a second touch input applied to at least part of the haptic modules, wherein second visible information associated with the second touch input is displayed on the display module in response to the second touch input, the second visible information displayed on the display module mirroring the second touch input detected by the haptic modules, and wherein new visible information is displayed on the display module through a combination of the first visible information and the second visible information.
