Abstract
A multi-color image display system comprising a cathode ray type of tube having a single electron gun disposed for directing a beam of electrons onto an output image display screen provided with three juxtaposed segments of different phosphor materials which emit respective different color light when penetrated by electrons from the beam. The display system also includes a beam directing assembly coupled to the tube for deflecting the electron beam to scan respective raster patterns sequentially on the three segments of the output screen and varying the intensity of the electron beam accordingly to produce thereon respective different color component light images of the same subject matter, the outer images being inverted with respect to one another and the central image being oriented similarly to one of said outer images. Also, the display system includes an optical combiner assembly coupled to the output screen for providing equivalent optical paths for each of said different color component light images within the optical combiner assembly and for combining said different color component light images to display a single multi-color image of said subject matter.
