Dutch scientists use color-changing graphene bubbles to create ‘mechanical pixels’

Researchers from Delft University of Technology in the Netherlands have discovered what could one day be a new type of display technology: bubbles of graphene that change color as they expand and contract. Scientists say that these ‘mechanical pixels’ could eventually make screens that are more flexible, durable, and energy efficient than current LED technology. They caution, though, that the work is very much in its infancy; whether these graphene bubbles can make displays of equiva
