DISPLAY APPARATUS WITH OPTICAL CAVITIES

摘要

A display (1201) includes an array of light modulators (1208) that define a display plane, a light guide (1204) and front- and rear-facing reflective surfaces. The light guide (1204) 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.
