Abstract

Optical configurations for reflective direct-view colour LCD's are described that use various ways of modulating the intensity plus the angular distribution of the reflected ambient light. A new display configuration using polymer dispersed liquid crystal and dielectric reflectors is demonstrated, where bright colours can be achieved upon switching from specular to diffuse reflectance. In cholesteric texture LCD's the reflected intensity depends on the applied voltages, whereas the angular distribution depends on both the applied voltages and the thickness of the orientation layers.
