Abstract

This invention generally relates to displaying a substantially two-dimensional input image, and is particularly applicable for use in a head-up display. Display apparatus for displaying a substantially two-dimensional input image comprises: a first spatial light modulator configured to form a hologram on the basis of a first drive signal to phase modulate a beam of substantially coherent light; a second spatial light modulator comprising a plurality of pixels, the pixels configured to selectively amplitude modulate on the basis of a second drive signal the light modulated by the first spatial light modulator; and a controller configured to generate said second drive signal on the basis of said input image.
