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.
