Patent ID: 7948450

Claim:
An apparatus for allowing display modules to communicate information about themselves to other display modules in the same display panel, comprising a module-based display panel, wherein the display panel comprises one or more faces, wherein each face comprises a plurality of display modules, wherein each display module comprises at least three borders, wherein at least one of the borders is adjacent to another display module, wherein a transmitter, receiver or transceiver is located on each border that is adjacent to another display module, wherein the transmitters, receivers and/or transceivers are configured so that each transmitter or transceiver on a given display module is adjacent to a receiver or transceiver on an adjacent display module, wherein each display module has a unique identifier, wherein the transmitters or transceivers on a given display module transmit that display module's unique identifier to the adjacent receivers or transceivers within a bandwidth of 10 Kbps or less, wherein the receivers or transceivers on a given display module receive the unique identifier of each adjacent display module from the adjacent transmitter[s] or transceiver[s] within a bandwidth of 10 Kbps or less, wherein each display module sends its own unique identifier and the unique identifiers of the adjacent display modules to a main controller, and wherein the unique identifiers are used by the main controller to determine the location of the display module within a display panel.
