Abstract

This paper highlights recent advances toward flexible cholesteric displays including new night vision applications for military use and full color. Particular emphasis is paid to recently developed encapsulated cholesteric liquid crystals that are necessary for printing and coating the materials as well as prevent erasure of the image during flexing or handling the display. The paper presents recent results from encapsulation of cholesteric materials using polymerization induced phase separation and their progression towards thin flexible plastic based cholesteric displays. Several other key issues in the transition from smooth rigid glass substrates to flexible plastic substrates including spacing control and preparation of surfaces are discussed. Lastly, the night vision mode and night vision applications of cholesteric displays are also presented.
