Abstract:
A display device and a haptic feedback method having the same provide a display panel which displays an image, a cover window on a first surface of the display panel and including a tactile pattern, and an actuator which is disposed on a second surface opposite the first surface of the display panel and overlaps the tactile pattern in a width direction of the display panel. The actuator outputs a sensing voltage according to applied pressure and generates vibrations according to applied driving voltages.
