ELECTROLUMINESCENT LAMP DRIVING CIRCUIT AND METHOD

摘要

A driving circuit for driving an electroluminescent lamp is disclosed. The driving circuit includes an alternating current (AC) voltage generator for providing at an output an AC output voltage waveform for driving an electroluminescent lamp and a controller for controlling the phase and polarity of the AC output voltage waveform. The controller is operable to reverse the phase and polarity of th e AC output voltage. In one embodiment, the AC voltage generator includes a transformer.
