ABSTRACT
This study demonstrates an electro-optical controllable smart window based on a liquid crystal device. The device integrates a photoconductive electrode based on TiOPc films into a liquid crystal shutter based on polymer-stabilised homeotropic aligned nematic liquid crystals (PSLC) connecting in series. The PSLC light shutter is transparent in electric field-off state; it scatters light as it switches to multi-domain structures in electric field-on states. The TiOPc film has an optically controllable impedance that manipulates the electric field on the PSLC film. The window transits into multi-transmission states according to the intensities of exposure light with an extra applied bias voltage.
