These Two-Way LEDs Can Harvest Light and Detect Hand Gestures

Combining multiple products into one can save a ton of space. Now researchers are developing new two-way LEDs which can be controlled with touchless gestures and can charge with ambient light.

The new screens can sense light, emit light, and collect energy all in one. The device relies on a newly emerging technology, two-way LEDs. Soon, digital displays will be able to charge and look right back at you at the same time.

Powering LEDs with Quantum dots

The two-way LEDs rely on an older technology: quantum dots.
