<p>A display arrangement consists of a tubular envelope with fluorescent stripes running along its length, localised portions of which are illuminated by different electron guns which produce flood beams of electrons. Field electrodes which surround each electron gun determine 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 colours, to produce a coloured display.</p> |
