We introduce a new method for evaluation of sparkle of the combination of display and AG‐layer by application of a weighting of the Fourier amplitudes of the random luminance modulations that are perceived as sparkle, according to the contrast sensitivity function of the human visual system. This new approach provides improved sensitivity to small sparkle variations, better control of parasitic low frequency components caused by non‐uniformities of display illumination and an improved match to visual ratings with subtle differences in the low sparkle region.
