Abstract

A display device comprises red, green, and blue laser sources; a Spatial Light Modulator (SLM) comprising at least one diffraction grating (10) recorded in an electrically variable refractive index material; a control circuit coupled to the SLM; an image generator; and a light stop (20). The SLM is illuminated with a red light at a first angle, green light at a second angle and blue light at a third angle which defines a viewing direction. Diffracted red and green light and undiffracted blue light emerge from the SLM in the viewing direction. Undiffracted red and green light and diffracted blue light are blocked by the stop after emerging from the SLM. I one embodiment, the SLM comprises one Bragg grating which diffracts red and green light into the viewing direction and the blue light away from the viewing direction. In another embodiment, the SLM comprises superimposed red, green and blue diffracting Bragg gratings.
