Abstract: A display device includes a display panel, a touch sensing layer which is disposed on a first surface of the display panel and senses a touch input of a user, a first vibration device which is disposed on a second surface of the display panel and generates vibration according to driving voltages. The first vibration device generates a first vibration in response to a first touch input of the user to provide a first haptic feedback.

Abstract: A display device may include a display panel, a touch member disposed on the display panel and configured to sense a touch signal, a cover panel sheet disposed under the display panel and having an opening via which at least a part of the display panel is exposed, a first vibrating element disposed in the opening, a touch drive chip electrically connected to the touch member and configured to detect touch coordinates in response to the touch signal, a processor electrically connected to the touch drive chip and configured to receive the touch coordinates to generate a pattern signal corresponding to the touch coordinates, and a haptic drive chip electrically connected to the processor and configured to receive the pattern signal to control the first vibrating element. The first vibrating element may be operated differently for different periods of time.
