Abstract
A display system has light source, display panel, conic mirror, and polarized reflector. The light from the light source is filtered by a diffuse reflective polarizer to contain light in a first linear polarization (for example, s-polarized light). That light is directed by the conic mirror toward the polarized reflector, and is reflected toward the display panel displaying images. The conic mirror and the polarized reflector is shaped such that the light telecentrically and uniformly illuminates the display panel. The light is reflected from the display panel being patterned by the image and rotated into a second linear polarization (for example, p-polarized light). The rotated light passes through the polarized reflector for viewing.
