Patent ID: 7688280

Claim:
An expanded bit map display (“EBMD”) for mounting on a building surface having a plurality of irregularities associated therewith, the EBMD operable to display a plurality of images on the building surface for viewing from a distance, the EBMD comprising: a plurality of light fixtures mounted to the building surface without use of a substrate common to all of the light fixtures or a plurality of interconnected modular substrates, wherein the plurality of light fixtures is mounted to the building surface in an irregular pattern to account for the irregularities on the building surface so that, for at least a portion of the plurality of light fixtures, a horizontal distance and a vertical distance between a first light fixture and any adjacent light fixture are approximately unequal, such that the portion of the plurality of light fixtures is mounted to the surface in a non-uniformly spaced configuration, wherein the plurality of light fixtures presents a density ratio of light fixtures per unit area of the building surface, wherein a first portion of the plurality of light fixtures has a different angular orientation than a second portion of the plurality of light fixtures so that light emitted from the first portion of the plurality of light fixtures is angled in a different direction that light emitted from the second portion of the plurality of light fixtures, and wherein when viewed from the distance, a selected one of the plurality of images displayed by the EBMD is generally uniform; a protocol hub operable to communicate control protocol to each light fixture; and a central processor in communication with the protocol hub and operable to communicate control protocol to each light fixture via the protocol hub, such that when the plurality of light fixtures are mounted to the building surface and controlled via the central processor, the light fixtures are operable to produce the selected image.
