Bending a planar OLED with flexible sub/superstrate alters the optical structure resulting in change of optical characteristics. The critical angle variations in sub/superstrate with curvatures were studied theoretically. The variations of spectral radiant distribution in planar and cylindrically bent states, and at specified directions were measured and discussed.
