Abstract

Large display apparatus includes a plurality of modular display units each having an image projector for projecting a section of a large composite display, and a light-transmissive screen located and dimensioned with respect to its projector to receive its respective section of the display in a slightly contracted form with respect to the overall display to be viewed, so as to leave a bare margin around the outer edge of a size such that the refraction of the light when transmitted through the screen will diverge the light to the outer edges of the viewing side of the screen, thereby minimizing mullions between adjacent screens without losing any part of the image content of the respective sections of the composite display.
