- To realize the flexible audible display (FAD), polymer
dispersed liquid crystal(PDLC) is deposited on
PVDF(Poly-vinylidene fluoride) film with piezoelectric
property. With applied audio signal, it makes sound more
than 70 dB in 700 Hz-10kHz. In case of transparency it
is opaque and transmittance is less than 10% at 550nm
wavelength without bias voltage. It is turned to be
transparent and show transmittance of 66% with driving
voltage of 60V.
