Images with enhanced resolution are created with a display device comprising a non-transmissive light valve including addressable pixels, a light source that directs light to the light valve, and a lens positioned between the light valve and the light source, the lens directing light from the light source to the pixels on the light valve and the light valve directing light to viewing optics. The light valve is an integrated circuit ferroelectric liquid crystal device (ICFLCD), or other light valve arrays such as a digital light processor (DLP) display, having an array of addressable pixels. Such light valves may be mounted in a head mounted display.
