Patent ID: 7915831

Claim:
A gaming machine artwork assembly for use in a gaming machine having a controller, the gaming machine artwork assembly comprising: a carrier on which images to be illuminated are carried; an electroluminescent illuminating arrangement mounted on the carrier, the electroluminescent illuminating arrangement comprising at least one electroluminescent element associated with one of said images to be illuminated; a generator circuit arranged to generate a full wave alternating current signal; and a driver circuit electrically connected to said generator circuit and electrically connected to the illuminating arrangement, wherein said driver circuit includes a dedicated microprocessor executing software to individually and continuously drive each of the at least one electroluminescent elements using the full wave alternating current signal in response to a pulse-width command from said controller, said driver circuit being further arranged to pulse width modulate the full wave alternating current signal based on the pulse-width command to thereby vary a cycle characteristic of the full wave alternating current signal over a period of time, so as to allow an intensity of the illumination of the image to be varied.
