Abstract
An apparatus for controlling light emission and/or sensing in an array of optical elements. An infra-extensible array having a plurality of subarray display circuits interconnected with neighboring subarray display circuits. Each subarray display circuit is configured with a processor and a plurality of output and/or input elements. Messages and instructions can be propagated from one subarray display circuit to another to provide local processing relating to input and output elements, such as changing the pixels in the display from a subarray display circuit in response to locally sensed conditions or those communicated from neighboring subarray display circuits. Apparatus is infra-extensible as both the number of processors for executing display/sensor programming, and the number of communication channels available through which instructions can be received, increases automatically in response to increasing the number of subarray display circuits within the apparatus.
