Summary

A new study led by MIT researchers could drive the development of more energy-efficient digital displays—such as flat-screen TVs, augmented and virtual reality headsets, smartphone screens, medical imaging devices and even large-area ambient lighting surfaces—that also generate richer, brighter colors. The MIT scientists, in collaboration with researchers at Samsung, studied the microscopic changes that occur inside LEDs that use electrically excited quantum dots, which are precisely shaped nanoscale semiconductor particles that emit extremely pure colored light. The research appears in Science Advances .
