Abstract
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.

47. A display device comprising a light valve comprising a front lens, a pixel layer, and a transparent layer adjacent to the pixel layer between the front lens and the pixel layer;
- the transparent layer comprising;
a liquid crystal first polarization rotator that turns the polarization direction of light by 90 degrees when turned on; a first layer of birefringent material thick enough to cause the images of spots to be seen to be displaced by a distance ‘
