Abstract

An electroluminescent panel driver circuit comprising a rechargeable battery and an electroluminescent panel. The electroluminescent panel comprises a front electrode and a rear electrode. The driver circuit is coupled to the battery and to the electroluminescent panel, and is configured to alternately charge the front and rear electrodes so as to cause the electroluminescent panel to emit light. The circuit is further configured to alternately discharge the front and rear electrodes to the battery, thereby re-charging the battery.
