New Tech Promises Dense, Efficient, Flexible Displays
A team at Oxford University has discovered a new type of display technology that consists of a simple thin film of phase-change material (PCM) between two thin films of transparent electrodes. The three layers can be applied to very thin, flexible Mylar sheets, creating a flexible display. The material only requires power to change state, so it holds an image without power, making it extremely power-efficient. The technique can currently create individual pixels as small as 300 x 300 nanometers, resulting in displays much sharper than today's. The team has also found a way to produce different colors by altering the size of the bottom electrode. Although the work is still in its early stages, the team has filed a patent and is working to commercialize the technology through Isis Innovation, Oxford University's technology commercialization company.
