Its principal technology, SPD-SmartGlass, uses suspended-particle devices to change glass or film from transparent to shaded or darkened when an electrical current is applied. This enables users to control sunlight, glare, heat and privacy while preserving visibility through the glazing. The company does not primarily operate as a conventional glass manufacturer. Instead, it licenses its intellectual property and technology to manufacturers and other commercial partners that incorporate SPD-SmartGlass into products. Applications include automotive sunroofs and windows, aircraft windows, architectural glazing, marine products and specialty displays. Research Frontiers was founded in 1965 and is based in Woodbury, New York. Its technology is marketed through licensees serving international automotive, transportation, architectural and specialty-glass markets. Joseph M. Harary has served as the company's president and chief executive officer.AI Generated. May Contain Errors.
