Abstract
A driving device for driving a discharge tube, wherein a pair of electrodes is formed on a piezoelectric transformer, and a voltage, which is periodically inverted, is applied to the electrodes. This design makes it possible to take out high voltage from the piezoelectric transformer due to the piezoelectric effect, ignite a discharge tube, and keep the discharge tube ON. Thus, a smaller and thinner driving device for a discharge tube can be achieved.
