Abstract: A layered light guide structure has a number of planar light guides arranged in a stack to receive a number of different color light beams from the edge of the light guides. Each of the planar light guides has one or more diffractive structures imparted or provided on its upper surface. The diffractive structures on each light guide are configured to diffract light of a particular wavelength range so that they efficiently diffract the guided light within that light guide. The diffractive structure can be one or more keypad symbols such that the layered light guide structure can be used as a keypad. The symbols can be pixelized such that the pixels can have different color patterns. The diffractive structure can also be a simple patch so that the layered light guide structure can be used as a back-light source.

Abstract: An apparatus includes a sample-and-hold display with a plurality of transmissive aperture holes, and an electroluminescent backlight source with a plurality of delimited emissive areas. A dedicated delimited emissive area is associated to each transmissive aperture hole of the sample-and-hold display. A display control component updates the sample-and-hold display with a predetermined refresh rate. A backlight control component activates different portions of the electroluminescent backlight source sequentially, each portion comprising a plurality of the emissive areas.

Abstract: A display device comprising: display element switchable to adjust the transmission of light therethrough; and a reflector located behind the display element for receiving ambient light transmitted through the display element and reflecting it back through the display element; wherein the diffusivity of the reflector is adjustable.
