Flexible Cholesteric liquid crystal displays have been rapidly maturing into a strong contender in the flexible display market. Encapsulation of the Cholesteric Liquid crystal permits the use of flexible plastic substrates and roll-to-roll production. Recent advances include ultra-thin display, laser-cut segmented displays of variable geometry, and smart card applications. Exciting technologies such as simultaneous laser-edge sealing and singulation enable high volume production, excellent quality control and non-traditional display geometrics and formats.
In this paper, we describe the state of the art of the cholesteric display technology including it’s applications. Development of new flexible cholesteric displays will also be presented with discussion of both the phase separation and emulsification approaches. Full color displays using ultra thin 12µm substrates will also be discussed as shown.
This paper describes new ultra-thin multicolor cholesteric liquid crystal displays will all functional layers coated sequentially on a single flexible substrate. Shared electrode driving is implemented for the first time to drive a passive matrix multicolor emulsion based displays comprising of three stacked layers of cholesteric droplets embedded in a polymer matrix.
We report on highly flexible layered full color cholesteric displays built using ultra thin substrates with encapsulation through the phase separation approach. Recent progress of the state of the art of the cholesteric display technology will be presented as well.
The state of the art of flexible bistable cholesteric reflective displays at Kent Displays will be reviewed in this paper with emphasis on full color displays using ultra thin 12 µm substrates. Current trends in application will be discussed as well.
