Abstract
A display unit has modular groups of light emitting elements or pixels. A light emitting element in the display unit can be used as a light receptor for accepting control information without needing to connect the display unit to a network or a controller.
Claims22
A method comprising:
- providing a display comprising a plurality of display panels that are releasably coupled;
- providing that each display panel comprises a plurality of light emitting elements;
- allowing a first display panel of the plurality of display panels to be decoupled from a second display panel of the plurality of display panels and removed from the display;
- allowing a third display panel to couple to the second display panel to replace the first display panel in the display;
- configuring a first light emitting element of the third display panel to emit a first wavelength of light in a first range of wavelengths and detect a second wavelength of light in a second range of wavelengths, wherein the first and second ranges of wavelengths are different ranges of wavelengths;
- configuring a second light emitting element of the third display panel to emit a third wavelength of light and not detect light,
- configuring a third light emitting element of the third display panel to emit a fourth wavelength of light and not detect light, wherein the first, third, and fourth wavelengths are different wavelengths;
- providing for the first light emitting element to receive a coded light signal transmitted from a control unit, wherein light of the coded light signal includes the second wavelength and the coded light signal includes address information;
- and
- configuring a processor to communicate with the third display panel using the address information.

A method comprising:
- providing a display comprising a plurality of display panels that are releasably coupled, wherein each display panel comprises a plurality of light emitting elements;
- decoupling a first display panel of the plurality of display panels from a second display panel of the plurality of display panels for removing the first display panel from the display;
- coupling a third display panel to the second display panel for replacing the first display panel in the display with the third display panel, wherein a first light emitting element of the third display panel is adapted to emit a first wavelength of light in a first range of wavelengths and detect a second wavelength of light in a second range of wavelengths, the first and second ranges of wavelengths are different ranges of wavelengths, a second light emitting element of the third display panel is adapted to emit a third wavelength of light and not detect light, and a third light emitting element of the third display panel is adapted to emit a fourth wavelength of light and not detect light, wherein the first, third, and fourth wavelengths are different wavelengths;
- transmitting a coded light signal to the first light emitting element, wherein light of the coded light signal includes the second wavelength and the coded light signal includes address information;
- receiving by the first light emitting element the coded light signal;
- and
- setting an address for the third display panel based on the address information.

A light emitting display system comprising:
- a plurality of display units, wherein the display units are detachably coupled to form a display portion of the light emitting display, each display unit is individually detachable from the display portion without detaching other display units from the display portion,
- each of the display units comprises a light emitting element adapted to emit light in a first range of wavelengths and adapted to detect light in a second range of wavelengths,
- the first and second ranges of wavelengths are different ranges of wavelengths, and
- each display unit has a unique address assignable individually via coded information transmitted to the display unit in the second range of wavelengths and the coded information comprises first address information for an address for the display unit;
- and
- a processor, electronically coupled to the display units, wherein the processor is adapted to receive the first address information from a first display unit of the plurality of display units when at least one of the light emitting elements of the first display unit receives the first address information in the coded information that is transmitted in the second range of wavelengths to the first display unit the processor is adapted to electronically address the first display unit of the plurality of display units with second address information that includes the unique address for the first display unit, and the second address information is based on the received first address information.
