OLED on curved substrate

摘要

Devices and components are provided that include a curved outcoupling component and an OLED, where the outcoupling component provides up to 100% outcoupling of light emitted by the OLED into air. The outcoupling component has an outer radius R and includes a material with a refractive index n. The OLED is in optical communication with the outcoupling component and disposed such that each emissive element of the OLED is within a distance r measured from the center of curvature of the surface at the outer radius R, such that R - r > ( n - 1 ) r.
