Abstract

A directional illuminator for a display apparatus includes a switchable diffuser for tuning a divergence of a light beam illuminating a display panel of the display apparatus. The tunable divergence of the illuminating light beam translates into a tunable exit pupil size at the eyebox of the display apparatus, which may be matched to a pupil size of a user's eye, thus providing a configurable illumination of the eye pupil. A tiltable reflector in an optical path of the illuminating light beam may be used to shift the location of the exit pupil at the eyebox of the display apparatus.
