The present invention provides an electro-optical device comprising a cell of polymer-stabilized blue phase (PSBP) liquid crystal under an electrical field and a method of controlling the reflection and transmission of an incident electromagnetic radiation such as visible light, by way of controlling the electrical field. The invention exhibits merits such as cost-effectiveness; simpler manufacturability due to the removal of requirements of polarizer and color filter; and fast switching, among others.

Electro-optical device and method for controlling color with polymer stabilized liquid crystal

This invention relates to a method of fabrication of liquid crystal light modulating devises having electrically tunable spectral wavelength and more particularly, to a cholesteric liquid crystal display with electrically switchable colors. The cholesteric light modulators may be fabricated by applying a plurality of layers to maximize the light modulation. It also features a polymer composite or polymer-network stabilized cholesteric liquid crystal with electrically switchable Bragg reflected wavelength within a predetermined range of spectral wavelength.
