Abstract:
reflective cholesteric liquid crystal displays (Ch-LCDs) because they are lightweight, low power flat-panel displays. Furthermore, Ch-LCDs can be made bistable which allows for the manufacture of large area, high- resolution displays without the need for expensive, difficult to manufacture active matrix addressing schemes. Also, the bistability enables flicker-free operation. Currently, these displays are made using glass substrates. However, some applications require rugged (i.e., nonbreakable), flexible displays. The use of a plastic substrate would fulfill these requirements. The transparent metal indium tin oxide (ITO) is currently used as the conducting electrode on glass as well as plastic substrates. While TO works well with glass, it does not adhere as well to plastic, is brittle, and has a tendency to break under constant bend conditions. In this paper, we investigate substituting the more robust conducting polymer for TO as the display electrode and determine the feasibility of producing a reflective Ch-LCD using plastic substrates with conducting polymer electrodes.

Reflective cholesteric liquid crystal display (Ch-
LCD)[1] is a bistable device which consumes less power
than the general reflective STN or TFT displays, Due to its
bistability. the driving voltage is required when refreshing
the screen. This power saving feature is especially
important for reading books or magazines. An ordinary
people may take 2-3 minutes to finish reading a page. Thus,
Ch-LCD is a strong contender for electronic newspaper or
books.
