ABSTRACT:
Color display apparatus including a color display tube in which a single electron beam is scanned in television raster fashion across the input surface of an electron multiplier (16) adjacent a screen (14) comprising a repeating pattern of three different color phosphors, and in which deflection of the beam emanating from the multiplier onto respective ones of the three phosphors is controlled by color selection electrodes (38, 40) adjacent output apertures of the multiplier. The apparatus includes driving circuitry using line stores (64) which performs line scanning at three times the standard rate and controls switching of the color selection electrodes so as to display in turn the three color components of each standard picture line during the standard line period. Vertical scanning may be effected continuously or in stepped fashion.
