Specular reflections often interfere when viewing displays. Anti‐glare surfaces reduce specular reflections but introduce diffuse haze. Predicting ambient contrast requires separating these components. Decreasing aperture size in the variable aperture source method separated specular from diffuse reflection, thus quantifying how anti‐glare surfaces effectively mitigate disturbing glare on electrophoretic ePaper displays.
