Abstract
There is provided a display screen configurable via optical signals to display an image. The display screen is formed of an optical waveguide having a display surface and supporting a plurality of pixels for displaying the image on the display surface of the optical waveguide. The optical waveguide is arranged to guide a multiplexed signal in optical form to a plurality of pixel controllers, each coupled to at least one of the pixels and configured to demultiplex the multiplexed signal and thereby extract a component signal associated with the at least one pixel for controlling it to render an element of the image.
