ABSTRACT:
A display device comprises a light guide and a movable element. By locally exerting a force on the movable element by means of selection means, optical contact between the movable element and the light guide can be brought about. Light emanates from the display device at the locations where optical contact takes place. Measures are taken to employ the force exerted by the selection means as efficiently as possible. This can be achieved by making the force act at the location where the optical contact takes place and/or by reducing other adhesive forces (caused, inter alia, by differences in pressure, static charging, surface stresses, van der Waals' forces and/or chemical forces).
