Abstract
A display apparatus having a transparent image screen which contains a mosaic of four discrete images formed from pixels which are interwoven in a predetermined arrangement such that each of the images are selected by precise positioning of the screen in four different positions relative to a grid mask which masks out all but pixels of a selected image. A platen comprising a platen surface which is supported by a rib structure mounts the image screen and is moveable through a precise pattern for selecting the pixels, and thereby the image, to be projected. A pair of arms are coupled to the platen and an eccentric drive and are driven by the eccentric drive to advance the platen positively through the pattern.
