[OLED6-3] Chromaticity Performance Characterization of Curved OLED Light Sources
Planar light source , non-planar light source, cylindrical light source, spherical light source, Convex/concave light source
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.
