<p>A display includes a point source (1, 5) of activation radiation, or an array of such sources, a lens system (3) for collimating the radiation from the point source or array, a modulator (7) capable of controlling the transmission of the collimated excitation radiation, and a screen (13) capable of emitting a visible display when struck by the modulated activation radiation and since the light is produced by point sources, such as LEDs, accurate collimation can be achieved with no loss. This in turn means that the modulated light can be expanded to produce a seamless tiled display.</p> |
