PSCT for Switchable Transparent Liquid Crystal Displays

摘要

We developed a switchable diffuser for transparent liquid crystal displays. The diffuser is based on polymer stabilized cholesteric texture (PSCT) light shutter. It can be switched between a transparent state and a milky scattering state by applying voltages. The transmittance of the transparent state is near 90%. The reflectance of the scattering state is higher than 30%. We also developed a transparent ADS display with the PSCT, which has excellent viewing angle.
