The vibration transfer layer is disposed under the display panel and has a plurality of openings. The touch sensitive element is disposed under the vibration transfer layer.
Claims20
A display device comprising:
- a display panel;
- a vibration element under the display panel, the vibration element including an electro active layer that is configured to vibrate responsive to an application of voltage to the electro active layer;
- and
- a vibration transfer layer between the display panel and the vibration element, wherein at least a portion of the vibration transfer layer is in contact with the display panel such that the portion of the vibration transfer layer overlaps a display area of the display panel, and the portion of the vibration transfer layer overlaps a portion of the electro active layer that is overlapped by the display area;
- wherein the vibration transfer layer comprises a plurality of openings, and the vibration transfer layer configured to transmit the vibration generated by the electro active layer to the display panel.

A display device comprising:
- a display panel;
- a vibration element under the display panel, the vibration element comprising:
- an electro active layer;
- a plurality of first electrodes on a first surface of the electro active layer, the plurality of first electrodes separated from each other;
- and
- a second electrode on a second surface of the electro active layer that is opposite the first surface, the second electrode overlapped by the plurality of first electrodes on the first surface,
- wherein the electroactive layer is configured to vibrate responsive to applying a voltage to the electroactive layer based on a voltage difference between the second electrode and at least one of the plurality of first electrodes;
- and
- a vibration transfer layer between the display panel and the vibration element, wherein at least a portion of the vibration transfer layer is in contact with the display panel such that the portion of the vibration transfer layer overlaps a display area of the display panel, and the portion of the vibration transfer layer overlaps a portion of the electro active layer that is overlapped by the display area;
- wherein the vibration transfer layer comprising a plurality of openings that each correspond to one of the plurality of first electrodes, the vibration transfer layer configured to transmit the vibration generated by the electro active layer to the display panel.
