Caption

Chemist Mark E. Thompson holds new copper-based LEDs invented by him and a team of chemists that could be a cheaper option for TV and smartphone screens to produce the color -- including blue -- and light. Right now, the industry relies on iridium, an expensive precious metal, for LED light and color.
