Silicon X-tal (crystal) Reflective Display, a reflective liquid crystal micro-display from Sony used in the first commercially available 4K-sized projectors. The display chip has 4096 x 2160 pixels on one-and-a-half inches (diagonal) of a silicon chip. The design maintains a uniform, ultra-thin liquid crystal cell gap without any spacers in the image area, contributing to contrast performance, claimed as 4000:1. Its Vertically Aligned Nematic (VAN) liquid crystal changes state fast enabling speeds up to 200 f/s while minimizing image smear. HDTV-sized SXRD chips have been used in Sony consumer products, including a front projector and rear projection televisions up to 70 inches.
