Abstract

A display includes an array of light modulators that define a display plane, a light guide and front- and rear-facing reflective surfaces. The light guide includes a plurality of geometric light redirectors, and at least 50% of the light guide's rear surface is parallel to the display plane. The rear-facing reflective surface is parallel to the display plane and includes a plurality of apertures.
