LED displays are going to get much clearer thanks to a plasmonic cavity

A plasmonic cavity sounds like technobabble straight out of an episode of Star Trek, but it could be the key to making LED displays clearer and more efficient. The plasmonic cavity is a nanostructure originally developed by Stephen Chou of Princeton University to boost solar power efficiency, but he realized it might have applications in emitting light as well as absorbing it. That could mean better screens on your devices.
