OLED

Universal Display Corporation

A maker of the light-emitting materials that power many OLED displays, Universal Display designs and sells the phosphorescent "PHOLED" technology and materials used by big screen makers in smartphones, tablets, and TVs. It was founded in 1994 when investor Sherwin Seligsohn saw OLED research at Princeton University and licensed it to launch the company. The fun twist: its UniversalPHOLED tech lets displays harvest both kinds of light-producing energy states that ordinary OLEDs waste as heat, making screens brighter and more power-efficient.
