Researchers affiliated with ETH Zurich have devised a multifunction picture element, or pixel, that can both emit and measure light. Traditional pixels generally do one or the other – illuminating a display screen or capturing light in a camera sensor. A team led by David Norris, professor at ETH Zurich Optical Materials Engineering Laboratory, has found a way to combine the two...
