An organic light emitting diode (OLED) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compounds which emit light in response to an electric current.
OLED Full form – Organic Light Emitting Diode
A major area of research is the development of white OLED devices for use in solid-state lighting applications.
US physical chemist Ching W. Tang and Steven Van Slyke at Eastman Kodak built the first practical OLED device in 1987.
An OLED display works without a backlight; thus, it can display deep black levels and can be thinner and lighter than a liquid crystal display (LCD).
Transfer-printing is an emerging technology to assemble large numbers of parallel OLED and AMOLED devices efficiently.
