ABSTRACT:
An apparatus for displaying an image has a display area comprises a plurality of displays such as LCDs or CRTs each displaying a given part of the display area in a side by side arrangement facing in the same direction with gaps between them. A pair of arrays of converging lenses is provided in the path of light from the display area to the image. Each array comprises lenses having the same focal length, and lenses in respective arrays have different focal lengths. The arrays have different pitches and lie in parallel planes in an afocal arrangement. The arrays expand and/or laterally shift the given parts of the display area to form a viewable image of the whole display area in which the gaps between neighbouring parts of the image are less visible than the gaps between neighboring parts of the display area.
