Variables in production techniques will provide improved performance for varying types of Cholesteric Displays.

Abstract: The following discussion presents how modifying the alignment layer can create performance enhancements across all categories of Cholesteric Displays.

The treatment of a alignment coating on a cholesteric display in order to produce many desired optical effects is clearly presented in ”Super High Brightness Reflective Cholesteric Display” [A. Khan, X.-Y. Huang, R. Armbruster, F. Nicholson, N. Miller, B. Wall, and J. W. Doane, Society for Information Display 2001 International Symposium Digest of Technical Papers, 32, 460 (2001)] (patent pending).  Indeed the use of a polarizer with this approach allows one to create enhancements in innumerous ways. Working in either the scattered or reflective mode, in the visible or infrared, with long or short pitch materials, polymer stabilized or polymer free, displays can be made that give many different degrees of optical performance and bi-stability in the reflective, scattered, trans-reflective, and backlight modes.
