Swedish researchers create touch-sensitive, light-, fingerprint-, and pulse-responsive displays with LEDs made of perovskite.

Swedish researchers at Linköping University have developed digital displays with LEDs that react to touch, light, fingerprints, and user's pulse. The screens, made of perovskite, could lead to a new generation of displays for phones, computers, and tablets. The technology, published in Nature Electronics, has great potential for advanced features but needs improvement for commercial viability.
