New LEDs Promise to Make Your Smartphone Screen 400 Percent Clearer

The most advanced LED screens look amazing compared to what was on the market even a couple of years ago. But a Princeton engineer found a cheap new way of making LEDs not only brighter and more efficient, but also five times as clear. It even makes them last longer. Professor Stephen Chou is renowned for his 2012 nanotechnology breakthrough that increased solar cell efficiency by 175 percent. Now, he’s applied the same principle to LED technology. “From a view point of physics, a good light absorber, which we had for the solar cells, should also be a good light radiator,” said Chou in a press release. “We wanted to experimentally demonstrate this is true in visible light range, and then use it to solve the key challenges…
