Patent US 8,553,019

Construction of a pixel-based display using a set of pixel assemblies poured or placed into a display area or volume. Each pixel assembly has a means to produce a visible display output at its position and identify its own position within a 2-D or 3-D display space continuously or when needed. One or more image signals are distributed to the pixel assemblies collectively. Each pixel assembly uses its own self-detected position and other criteria to autonomously decide to which part of the signal(s) it will respond and what value to display as an output. Optionally each pixel assembly may also be able to: decode pixel identity encoded in the input signal(s) to implement a stroke/random access display; communicate with adjacent display elements in order to engage in collective action in local regions of the display; detect faults and remove itself from the display; and reprogram itself using an external signal.
