Abstract
A display device includes laser light sources of different colours and at least one light guide. The at least one light guide includes a light outlet including a plurality of exit portions, and is controllable to sequentially guide light rays emitted by the laser light sources towards different exit portions of the light outlet. A pixel of an image is displayed by: (i) determining a corresponding exit portion, based on a pixel location of the pixel in the image; (ii) controlling the laser light sources to emit light rays having a colour and an intensity representative of the pixel, based on intensity values of different colour components of the pixel; and (iii) controlling the at least one light guide to guide said light rays towards the corresponding exit portion from which the light rays exit.
