ABSTRACT:
A gaming machine artwork assembly includes a carrier on which images to be illuminated are carried. An electroluminescent illuminating arrangement is mounted on an operatively rear surface of the carrier. The electroluminescent illuminating arrangement comprises a plurality of electroluminescent elements, at least one element being associated with each image to be illuminated. A driver circuit is connected to the illuminating arrangement for driving the electroluminescent illuminating arrangement to illuminate selected electroluminescent elements of the arrangement on command from a controller of the gaming machine. The driver circuit includes individual drivers for each electroluminescent element for independently driving the electroluminescent elements and variably controlling the intensity of the illumination of the images with which said electroluminescent elements are associated.
