ABSTRACT:
A display arrangement consists of a tubular envelope with fluorescent stripes running along its length, localized portions of which are illuminated by different electron guns which produce flood beams of electrons. Each gun is situated within a switchable magnetic field which determines the angular direction at which the flood beam leaves the gun, and hence which one of the fluorescent stripes is caused to emit light. The stripes can be of three different primary colors, to produce a colored display.
