How Organic Light Emitting Diodes Revolutionized Displays

Explore the revolutionary impact of Organic Light Emitting Diodes (OLEDs) on display technology in this 37-minute APS Physics conference talk by Stephen Forrest from the University of Michigan. Delve into the evolution of OLEDs from their invention 30 years ago to their current market explosion, examining their potential to replace liquid crystal displays in mobile applications, virtual and augmented reality systems, monitors, and televisions. Learn about the nanometer-thin devices made with carbon-containing dye compounds, their attractive features including simplicity, flexibility, light weight, and ultrahigh efficiency. Discover the challenges still facing OLED technology, such as improving useful lifetime, enhancing light outcoupling, and developing cost-effective patterning methods for high-resolution displays. Gain insights into the future of display and lighting technology, including applications in white light production and transparent windows. Explore topics like electrophosphorescence, external quantum efficiency, industrial sector impact, and potential solutions to overcome current limitations in OLED development.
