Introduction:
The platform consists of an organic light emitting diode (OLED) fabrication system and a device assessment system. The fabrication system includes a glovebox system, a vacuum system, an evaporation-deposition system for organic compounds and a spin coater. The evaporation-deposition components and the spin coater are in the gloveboxes. The electroluminescence spectra, the quantum yields and the device operational lifetime can be measured with the device assessment system. This platform is designed for organic light-emissive substances exclusively.
