Provided are a drive device and drive method for a vacuum fluorescent display that can suppress brightness variations in display images and improve display quality. A drive device (1) for a vacuum fluorescent display (10) is provided with a positive electrode unit (11) in which a plurality of positive electrodes (11a) to which a phosphor is applied are disposed in a matrix shape and a negative electrode filament (12) that discharges electrons toward the positive electrode unit (11). The device is provided with: a first magnetic field generating means (30) that generates a first magnetic field (M1) perpendicular to the direction in which the positive electrode unit (11) and the negative electrode filament (12) face each other and that can periodically switch polarity; and a second magnetic field generating means (50) that generates a second magnetic field (M2) that is perpendicular to the direction in which the positive electrode unit (11) and the negative electrode filament (12) face each other and crosses the first magnetic field (M1) and that can periodically switch polarity. |
