Patent ID: 8288776

Claim:
A hybrid electric device using a piezoelectric polymer substrate, the hybrid electric device being constructed by forming an integrated unit in which a display device and a vibration-generating or -sensing device share the piezoelectric polymer substrate, wherein the hybrid electric device comprises: a flexible piezoelectric polymer substrate; an electrode pattern formed, by vacuum-depositing an electrode material on both surfaces of the flexible piezoelectric polymer substrate to form electrode thin films and by patterning at least one of the electrode thin films through a laser irradiation-based room-temperature dry etching process; a light-emitting layer stacked on the electrode pattern and an electrode stacked on the light-emitting layer, wherein the display device uses the electrode pattern on which the light-emitting layer is stacked and the electrode stacked on the light-emitting layer as electric conductors, and the vibration-generating or -sensing device uses the electrode thin films formed on the both surfaces of the flexible piezoelectric polymer substrate as electric conductors.
