“Organic light emitting diode (OLED) displays using DuPont technology produces imagery so bold, you won't believe your eyes. It’s no wonder you get such amazing contrast and clarity, since DuPont has been perfecting the technology in this emerging industry for nearly 15 years. DuPont OLED technology represents the next-generation technology for higher performance and lower cost large-area flat panel displays as well as playing a critical role in enabling more efficient future lighting solutions. DuPont offers a suite of innovative, high-performance, solution-based materials that can be printed and coated at high speeds. All the materials are designed to work together to provide excellent device performance, quality, efficiency and lifetime. Using the DuPont liquid printing process and suite of innovative, high-performance, solution-based materials, display manufacturers may achieve an in-pixel thickness aperture of >95% and a thickness variation of ~2 nm across the plate with long-range uniformity >90%.”

“OLEDs are semiconductors made of layers of organic material. They create light in much the same way as a traditional LED does: Electrons and holes meet and cancel each other out, releasing photons. Manufacturers make the screens by spraying organic films onto a substrate, typically glass or plastic, printing out patterns the way ink dots are printed on paper.”

"Usually, the total thickness of the organic materials in OLED structure is about 100 nm and the ITO thickness is determined by considering good electrical conductance and high transparence." Jeong and Takezoe (2012)
