Audible OLED device on flexible PVDF substrate with laser patterned ITO electrode

Abstract

For the new combination of audio and display devices on flexible polymer substrate, we present the audible OLED device on piezoelectric polyvinylidene difluoride (PVDF) with ITO electrode prepared by roll to roll sputter coating and laser ablation pattern technique. Our flexible audible display (FAD) device showed the luminescence as well as the sound generating functions under the structural schematics with two device characteristics sharing the one flexible polymer substrate for the next generation "superposed" electronic devices
