LEDs, or light-emitting diodes, have changed the world – and continue to do so. This energy-efficient electronics technology came from decades of design and discovery in engineering. Dr. Russell Dupuis is one of the engineers behind LEDs, and he recently was one of five winners of the Queen Elizabeth Prize for Engineering for his work in this technology. Dr. Dupuis explains his contribution to creating thin-film electronics necessary for LEDs, starting from his university days in Illinois, and he also discusses its implications for the future. He currently is a professor of electrical engineering at Georgia Tech. This is a joint episode with The K12 Engineering Education Podcast and Engineering Word Of The Day.
