Corning Iris™ Display Glass
Categories:	Ceramic; Glass; Optical
Material Notes:	Features outstanding transmission and minimal color shift, delivering bright displays with rich, accurate colors. Iris Glass is a glass light-guide plate (LGP) for edge-lit LCD TVs. Due to its intrinsic rigidity and dimensional stability, it outperforms plastic and allows TV manufacturers to significantly reduce set thickness and create TVs with slimmer bezels. Information provided by Corning Incorporated.
