摘要： 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.

摘要： Disclosed herein is a method of assembling an array of light emitting diode (LED) dies on a substrate comprising: positioning dies in fluid; exposing the dies to a magnetic force to attract the dies onto magnets that are arranged at pre-determined locations either on or near the substrate; and forming permanent connections between the dies and the substrate thereby constituting an array of LED dies on a substrate.

摘要： Disclosed herein is an illumination system including an array of LED light sources for emitting light encoded with a modulation pattern, an array of sensors and a space characterization unit. The array of sensors receives emitted light scattered by an object. Each sensor determines a distance between the corresponding light source and the object using the modulation pattern. The space characterization unit uses the distance from each sensor to generate an elevation map indicating a presence of the object.
