Abstract
In some embodiments, a device includes a light-emitting display, and an optical emitter positioned behind the light-emitting display. The optical emitter is configured to emit light through the light-emitting display. A processor is configured to synchronize a first illumination timing of the optical emitter and a second illumination timing of the light-emitting display. In some embodiments, a device includes an optical transceiver processor and a display processor. The display processor is configured to output timing information to a light-emitting display and to the optical transceiver processor, and the optical transceiver processor is configured to cause an optical transceiver to emit or receive light in synchronization with the timing information output by the display processor.
