Abstract
A holographic display comprises a light source and an Electrically Addressable Spatial Light Modulator (EASLM) in the path of the light source. A light guide is arranged to guide light from the EASLM to each of a set of tiled regions of a OASLM in turn. The Optically Addressable Spatial Light Modulator (OASLM) has a monostable light modulation property which is changed from a first state to a second state by incident light.
