Abstract

PURPOSE: To make manufacture and driving easier by reducing the number of fetching electrodes by causing light to emit by selecting voltage for each grid facing fluorescent screen dividedly covered with plural kinds of fluorescent substances and electron ray source.
CONSTITUTION: The segments 21W27 are covered dividedly with the zinc-activated zinc oxide fluorescent substance a emitting a greenish white color light and the europium-activated tin oxide fluorescent substance emitting a reddish orange color light, for example. Then, a pair of a wire- or comb-like grids 28 and 29 are provided in close proximity to the front of these fluorescent substances in such a way that the grid 28 is faced only on the fluorescent substance a, whereas the grid 29 is faced only on the fluorescent substance b side. When applying a voltage of 20V to both the grids 28 and 29, a mixed color of greenish white color and reddish orange color is emitted and also when applying the voltage of 20V to only one fluorescent substance, a greenish white color or a reddish orange color is emitted. Thus, multi-color display can be made by using 11 fetching electrodes.
