    Abstract: A device is disclosed that is capable of independently modulating the transparency and emissive color of individual pixels that comprise an electronic display. Modulating the transparency of a transmissive layer allows a darkened or semi-darkened foreground field to be provided on the display. Modulating the color of an emissive layer further makes controllable the brightness and color of the foreground field. When these parameters are controlled, the display can generate partially transparent or opaque graphical elements that appear over the scene behind the display. In some embodiments separate emissive layers are provided on the front and back side of a central transmissive layer, thereby allowing different graphical information to be provided on the front and back side of the display. In other embodiments multiple transmissive and emissive layers can be stacked together, thereby allowing three-dimensional imagery to be generated without the need for viewers to use specialized viewing glasses.
