摘要：
The invention provides an apparatus and a method for driving a cathode discharge tube such that the discharge starting voltage can be lowered by simple construction. At the start of lighting a cathode discharge tube light, AC voltage applied to the cathode discharge tube is raised at a speed slower than a rise speed of the cathode discharge tube. By lighting the cathode discharge tube in this way, the lighting start voltage can be reduced.
