Abstract
A dual mode display (100) includes a monochrome reflective direct view display (110) and a full color virtual display (150) located behind the monochrome reflective direct view display. The monochrome reflective direct view display includes a display panel (112) having a first pixel arrangement and a narrowband reflector (114) located behind the display panel. The virtual display has a second pixel arrangement, wherein each pixel emits light in one of three primary color bands through the monochrome reflective direct view display, and wherein the light emitted by each pixel, in combination with light emitted by other pixels of the virtual display, generates a full color virtual image from the dual mode display. In one embodiment the virtual display is a virtual high information content display and the three primary color bands (205, 210, 215) do not overlap a first color band of the narrowband reflector (220).
