摘要

An OLED device suitable for automobile ceiling lights has been designed, fabricated and evaluated. The OLED structure is fabricated on a thin (120 μm), flexible polymer foil with integrated micro-optics to achieve customized beam shaping in the far field. A pixelated OLED structure matched to a patch-pad microlens matrix was used to convert the OLED Lambertian emission into a Gaussian-shaped illumination beam. Both refractive and diffractive microlenses were investigated. The integrated micro-optics OLED architecture reduces light losses due to waveguiding effects and effectively increases the light extraction by up to 70%.
