Abstract: PROBLEM TO BE SOLVED: To resolve a problem that the realizing of eliminating color drifts becomes relatively complex and the problem of the voltage breakdown of a screen by providing a reproducing state in which at least anode parts are in low voltage levels and corresponding cathodes are biased to radioactive states. SOLUTION: The control method of a cathode light emitting screen is formed by providing a reproducing state in which at least anode parts are in low level voltages and corresponding cathodes are biased to radioactive states. That is, for example, color subframe periods Tr, Tg, Tb are provided in an interval in which respective strips of colors of red, green and blue are successively biased in a frame duaration period T. Moreover, a dead time Td corresponding to the reproducing stage is provided. In the dead time Td, all anode stripes of three colors are not biased. Conversely, the pair of cathode gates are biased so that electric radiations are generated.
