“Sparkle” occurs when non-glare glass is used with a display and has a surface where the etch pattern size and roughness has variation resulting in inconsistent, insufficient, or unpredictable light diffusion effects in select areas of the glass. An observer sees this variation projected through the glass as artifacts of distorted pixel color, shape, pinpoint light leaks, or points of reflection that are not sufficiently or correctly diffused which were not present in the display itself.
These artifacts are referred to as “Sparkle” and affect perceived display resolution and image quality. Low Sparkle Non-Glare Glass provides sharp rendering of images with increased clarity for easily readable devices in direct sunlight. Download the datasheet for more additional information.
