Abstract

PURPOSE: To make a rapid progress of improvement for the information transfer ability, by means of controlling the applied anode voltage to change a proportional rate of intensity of a plurality of luminous colors.
CONSTITUTION: To the same display element anode 2 on an insulation layer 1 is applied a phosphor, to construct a phosphor layer 3. The phosphor is constructed by a plurality of kinds of phosphor with its luminous start voltage and display color different from each other. An appropriate selection of applied anode voltage causes a brightness of the required luminous color to become higher than that of the rest of the luminous color, capable of obtaining a display of the required color.
