Document Type and Number:
Japanese Patent JP5666588
Kind Code:
B2
Abstract:
The present invention concerns an electronic device (10) comprising a display layer (44) configured to visually display images; a touch sensitive layer (36) located on a front side of the displayer layer (44) and configured to sense if an object touches the touch sensitive layer (46) and to sense where the touch sensitive layer (36) is contacted; a composite piezoelectric assembly (26) placed on a backside of the display layer, wherein the composite piezoelectric assembly comprises a first electrode layer (38), a second electrode layer (42), and a composite piezoelectric layer (40) between the first electrode layer and the second electrode layer; and a drive circuit (32) configured to apply an alternating voltage to the first electrode layer and the second electrode layer.
