Abstract
A method is disclosed for making a liquid crystal composite including a dye. The method comprises forming volumes in which a liquid crystal material is surrounded by a containment medium, forming a dye dispersion, combining the dye dispersion and the volumes of liquid material, and treating that combination to facilitate the transfer of the dye into the volumes of liquid crystal material.
