Brilliant Cosmetic Film for Ambient Displays, with Cholesteric Liquid Crystal

摘要

A brilliant cosmetic film with polymerized cholesteric material (PCM) has been developed. The film features a variety of colors by helical pitch gradients, diffusive texture, and arbitrary color patterns. It hides the display when turned off, and transmits display images when turned on. We believe it could change the display in the Off-state from the conventional black wall to specially designed decorations. In addition, they can be applied to hidden sensors.
