Top Emission PIN OLEDs on Reflective Bottom Contact

Novaled provides its customers top emission-type OLEDs with doped charge carrier transport layers, optically optimized device design and proprietary materials. Top Emission PIN OLEDs are especially suited for AM-applications as they allow higher aperture ratios. Thus, such OLEDs operate at lower brightness, resulting in increased life-time and power efficiency. Novaled's top emission PIN OLEDs have the following advantages for customer applications: good injection and transport extremely low operating voltage highest efficiency inverted and non-inverted stacks transparent OLEDs possible integration onto transparent and opaque substrates suitable for flexible displays based on metallic foils etc. tailored for active matrix environment The top PIN OLEDs are especially suited for AM-application because of the high efficiency and long life-time. Top emission AM-solutions allow for higher aperture ratios, therefore the OLED can be operated at a lower brightness and the life-time and power efficiency are increased.
