Abstract
A heterogeneous blend of small electron-donor organic molecules and polymerizable monomers is flash evaporated to provide a molecular-level vapor-phase mixture, which is then condensed and cured in-line as a homogeneous liquid layer on a flexible web containing an anodic layer. The procedure is repeated with an electron-acceptor organic substance, which is deposited over the electron-donor layer. A metallic cathode is then deposited over the electron-acceptor layer and the composite OLED product is packaged. The electrical characteristics and the thickness of the metallic cathode and the composition of the polymer layers are selected such as to produce the gasification of elemental carbon generated by dielectric breakdowns and the oxidation of any exposed cathodic surface, thereby providing a built-in mechanism to prevent the propagation of the damage caused by electrical shorts.
