Abstract
An apparatus displaying a sequence of images on an electroluminescent lamp is disclosed. The apparatus includes an electroluminescent lamp, a plurality of trace leads, and an overlay adjacent to the electroluminescent lamp. The lamp has a front electrode and a plurality of pixels, the pixels being independently illuminable portions of the lamp, and each pixel includes an electroluminescent material and a rear electrode. The trace leads are connected to the rear electrodes, with each rear electrode connected to one trace lead and each trace lead connected to more than one rear electrode. The overlay has a translucent or transparent material and a plurality of images interwoven together on the translucent or transparent material. Each image corresponds to selected pixels on the lamp. Power supplied to the front electrode and selected rear electrodes creates an electric field therebetween, whereby pixels to which power is supplied are illuminated to display an image. A sequence of the images may be displayed by successively selecting other of the rear electrodes. Such a sequence of images may form animation.
