Polymer-stabilized white reflective cholesteric displays

We report results of optical and electro-optical properties of a white reflective display from polymer-stabilized cholesteric texture (PSCT) technology. The new PSCT system is consisted of a cholesteric liquid crystal, photoinitiator and chiral monomer. After polymerizing at homeotropic texture of the cholesteric material, the PSCT display reflects white light at the planar texture, indicating a broad distribution of helical axes of the cholesteric material. When the cholesteric material is switched to the focal conic texture, the display reflects a black color with a black paint coated at the back panel.
