ABSTRACT:
A driving device (100) for driving a plurality of discharge lamps (14), and includes a controller board (11), a connecting board (15), and a group of high voltage lines (17). The controller board includes a controller circuit (13) for converting a received signal to a high voltage signal suitable to drive the plurality of discharge lamps. The connecting board includes a balance circuit for balancing currents flowing through the plurality of discharge lamps. The connecting board is substantially perpendicular to the controller board. The high voltage lines are connected to the controller board and the connecting board, and the high voltage signal from the controller circuit is output to the balance circuit via the high voltage lines.
