“GlassArray” is a high-speed, dimmable, intelligent glass system that can create animations by varying the transparency and translucency of small areas inside a pane of glass. The patented approach can be used for large-scale urban art and signage, but also for cladding onto building facades to selectively block sunlight and reduce AC costs. Other benefits include privacy control, switchable projection surfaces, and bird collision reduction. With GlassArray, architects, designers, and developers can create interactive walls, pavilions that can automatically provide dynamic shade from the sun, or retrofit existing buildings. The material has a high update rate, low maintenance and electrical consumption, and can be addressed by a variety of data protocols, including DMX.
