Abstract
A display system comprising a light source and a plurality of switchable elements, wherein each element is switchable at an element switching frequency in accordance with an element control signal between an "on" state in which light is directed from the light source onto a display, and an "off' state in which light is not directed onto a display. The light source being configured to generate a pulsed light source output at a light source pulse frequency.
