Electronic signs are all around us, giving directions or advertising the latest gadget. In ACS Energy Letters, researchers report that they’ve developed a dynamic display technology that dissipates heat instead of generating it when the color changes, cooling the surface underneath. They also showed the display could be attached to flexible backings and wrapped over skin. The passive cooling mechanism could usher in the next generation of sustainable, flexible outdoor signs and smart devices.
