… and get a response back? Possibly. Recent patents granted to Apple in 2017 and research by the leading LED chip manufacturers are pointing in this direction. Patently Apple reports the use a micro LED in an active matrix display to emit and sense light. “Display panels, systems, and methods of operation are described in which LEDs may be used for both emission and sensing,” blogs Jack Purcher. At the same time this technology is yet to settle: it is to bring together three streams into one delta: that of microLED chips suppliers (Nichia, Osram), display producers and technology transfer and assembly.
Okay, we may be dreaming, but imagine: a light emitting surface that lights up the space, displays an app interface, verifies the user identity and adjusts its settings, brings up custom news and content.
