Anti-glare films are applied to displays to minimize reflections and ensure information is viewable. The variable surface structure of the film allows ambient light to be diffused evenly but can also compete with the pixel geometry of the display as light is emitted through the film. A visual effect called sparkle can cause low display clarity. Measuring perceived sparkle ensures that the user experience drives the manufacture of anti-glare displays. In this Webinar, an expert on this topic presents a method for repeatable sparkle measurement across users, devices, and systems, with quantifiable results that correlate to human visual perception of display quality. Topics include the effect of sparkle on display quality and setting a sparkle tolerance based on human visual perception.
