摘要： Luminance life can be enhanced in a vacuum fluorescent display that is driven according to a dynamic drive scheme and that uses a phosphor having remarkable luminance saturation. A drive method for a vacuum fluorescent display, having causing a phosphor layer formed on an anode to display under low-energy electron excitation by the dynamic driving, wherein the phosphor included in the phosphor layer is a phosphor in which the luminance increases when a pulse width is reduced under conditions in which the Du is kept the same in the dynamic driving, and in which, after a voltage is applied to the anode and the luminance of the phosphor is saturated, the time at which the luminance value decreases to 10% of the saturation luminance value following stoppage of the voltage application is 200 μsec or more; and wherein the pulse width and pulse repetition period in the dynamic driving are made variable in the direction of maintaining the initial luminance of the phosphor as driving time elapses.
