A monocolour SXGA resolution LCoS microdisplay was used to demonstrate the features of the vertically aligned dyed cholesteric liquid crystal mode. It exhibits a very high brightness of 55% reflectance with an acceptable contrast ratio of over 3:1 when driven at 5v. Higher drive voltages provide better contrast ratios. Some important device parameters are discussed.
