Abstract
A reflective display can be configured around a waveguide illuminated with collimated light. A variety of light sources, light valves, light extracting devices, and light redirecting means may be employed to complete the display. The light extracting devices, light valves, and light redirecting means cooperate to selectively extract, attenuate, and redirect selected portions of the light in specific locations within the display.
