Abstract:
1. A plurality of interlocking pixel blocks, directed to serving as pixels, i.e picture elements, in graphics displays, each pixel block comprising: a first flat surface extending over a least a major portion of a region bounded by a generally polygonal outline in a first XY plane; a second flat surface extending over at least a major portion of a region bounded by a like polygonal outline in a second XY plane parallel to the first XY plane and separated therefrom by a designated Z axis thickness dimension; a plurality of edge facets corresponding to facets of the polygonal outline, each extending between a corner formed with said first flat surface and a corner formed with said second flat surface; at least a first and a second of said edge facets being configured with at least one tongue-and-groove pair consisting of a protruding tongue configured in a first region of each edge facet and a similar shape groove configured in a second region of each edge facet, the tongue and groove being shaped to fit and interlock with a mating groove and tongue respectively of an adjacent one of said pixel blocks, such that said pixel blocks may be assembled together in an interlocking manner at the edge facets to form a panel in a two-dimensional interlocked array of said pixel blocks; and at least one stability bar configured in each of said pixel blocks, located within a cross-sectional outline of the tongue-and-groove pair thereof, said stability bar extending from the first plane to the second plane, made and arranged to stiffen and stabilize a panel assembled from a plurality of said interlocking pixel blocks.
