1. A display device comprising a digital projector and a reflective surface mounted on a common frame, the digital projector comprising a light source, a projection lens and at least one additional optical element adapted to cause a projected image to be formed on the reflective surface, wherein the light passing from the light source through the projection lens is folded by more than 180 degrees in a plane containing the principal axis of the projection lens and a plane of symmetry of the at least one additional optical element before being reflected from the reflective surface,
wherein the reflective surface is an electrophoretic display, an electro-wetting display, an electrochromic display, a rotating bichromal display, or a reflective liquid crystal display, and
wherein pixels of an image from the digital projector are mapped 1:1 onto pixels of the reflective display.
