Abstract
Methods and devices including a light display transceiver device are disclosed. Disclosed methods and devices include a light source array including at least one pixel unit, the at least one pixel unit including one of a single pixel, a plurality of groups of cooperating single pixels, a combination of singles pixels and groups of cooperating single pixels, and a single group of cooperating single pixels. Control wires are joined with each of the at least one pixel units. A controller is joined with the control wires for controlling each of the at least one pixel unit. The light source array is configured to operate in at least one of three modes, a full-space-division-duplex (FSDD) mode, a half-space-division-duplex (HSDD) mode, and a time-division-duplex (TDD) mode. The controller causes the light source array to operate in one of the three modes.
