DISCHARGE LAMP DRIVING DEVICE AND ELECTRONIC DEVICE USING THE SAME

摘要

A driving device for driving plural discharge lamps. A controller circuit converts a received signal to a first high voltage signal and a second high voltage signal. A first balancing circuit is mounted on a first connecting board and connected to one ends of the discharge lamps. A second balancing circuit is mounted on a second connecting board and connected to the other ends of the discharge lamps. A first set of high voltage lines connects the controller board and the first connecting board, and the first high voltage signal is outputted from the control circuit to the first balancing circuit via the first set of high voltage lines. A second set of high voltage lines connects the controller board and the second connecting board, and the second high voltage signal is outputted from the control circuit to the second balancing circuit via the second set of high voltage lines.
