The impact of the radius of curvature on the emissive properties of curved displays is investigated. We compute the resulting distortion on viewing angle properties and we compare to experimental results obtained on a curved TV and a BEF film. We show that if the spot size/curvature ratio is below 0.5% the impact is negligible.
