Organic Light-Emitting Diodes (OLEDs) emit light with virtually no electricity. Lamps, televisions, mobile phone, and computer monitors are common applications. Additionally, OLEDs are bright, high-contrast, and extremely thin.
OLED screens are faster, brighter, and use far less energy than LED-based displays. As the technology develops, they will eventually cost less than LED displays.
OLED’s are literally and figuratively flexible: they bend. Consequently, this ability enables all sorts of interesting lamps. Curved OLED televisions already exist and bendable mobile phones are in development.
Eventually, inkjet printers will produce OLED’s, dramatically lowering costs.
In 1987, Ching Tang and Steven Van Slyke of Kodak invented OLED’s. Subsequently, as usual, Kodak failed to meaningfully commercialize the technology beyond patent licensing.
