Abstract
Multi-color image display apparatus including a cathode ray tube having an electron gun disposed for directing an axially emerging electron beam onto an output phosphor screen comprised of two portions, each of which is disposed symmetrically with respect to the emerging electron beam and is provided with a respective different color phosphor material. The apparatus also includes a deflection system coupled to the emerging electron beam for deflecting it sequentially in respective inverted raster patterns over the two portions of the phosphor screen to produce respective different color mirror images of the same subject matter. Also, the apparatus includes an optical system coupled to the phosphor screen for superimposing the two color mirror images to produce a single multi-color image.
