Abstract
A method of reusing micro-encapsulated cholesteric liquid crystals is provided. The method includes providing a display medium material containing a micro-encapsulated cholesteric liquid crystal and a dispersant. The display medium material is mixed with a solvent to form a mixture having a temperature of between 40° C. and 60° C. A centrifugal process is performed to the mixture for separating the micro-encapsulated cholesteric liquid crystal and the dispersant. Then, the dispersant and the solvent are removed to obtain the micro-encapsulated cholesteric liquid crystal.
