Abstract

A polymeric dispersed liquid crystal light shutter device and system and method for forming the same are disclosed. In one embodiment of the system, a catoptric form having a shape is subjacently positioned below a pre-cure or un-cured polymer dispersed liquid crystal (PDLC) light shutter device having liquid crystals dispersed in a polymer binder system between two substrates. Light is applied during curing. The liquid crystal microdroplet sizes vary according to the shape of the catoptric form such that domains of smaller liquid crystal microdroplet sizes correspond to the shape and domains of larger liquid crystal microdroplet sizes correspond to negative space relative to the shape. Upon tuning an electric field, the PDLC light shutter device changes states from presenting a surface having an image formed by non-scattering regions contrasted against opaque scattering regions, to a surface characterized by mostly or entirely clear, non-scattering light transmittance.
