We simulate the guiding and out‐coupling of light in strongly curved backlight units with edge illumination using a 3D ray‐tracing tool with custom light emission and scattering features. The impact of the display curvature is assessed regarding the uniformity and angular characteristics of light outcoupling in a complex backlight with position‐dependent bottom roughness, a diffuser element and a textured brightness enhancement film.
