Abstract
An emissive display device for producing images, has a plurality of first pixels each having an emissive area wherein the plurality of first pixels define a first viewing region, wherein each first pixel produces light emission which is visible when viewing the first side of the display device; and a plurality of second pixels each having an emissive area and wherein the plurality of second pixels define a second viewing region, wherein each second pixel produces light emission which is visible when viewing the second side of the display device, wherein at least a portion of the plurality of first and second pixels are interleaved.
