ENGINEERED ANTIGLARE SURFACE TO REDUCE DISPLAY SPARKLE

摘要

A transparent substrate having an antiglare surface with reduced display sparkle. The transparent substrate has a roughened antiglare surface and a diffraction element below the antiglare surface. The diffraction element reduces sparkle by filling gaps between sub-pixels in a pixelated display with orders of diffraction. A display system comprising the transparent substrate and a pixelated display is also provided.
