FIELD: gas-discharge equipment engineering, possible use in construction of monochrome and colored gas-discharge video-modules.
SUBSTANCE: method includes insertion of image of one or two modified sub-fields into image frame, within indication range of which a pulse for supporting charge is formed on selective indication electrodes.
EFFECT: increased number of brightness gradations, alternation of image brightness within broad range with preservation of high number of brightness gradations.
