Kopin Corporation designs and manufactures small form factor microdisplays and integrated optical systems for defense, industrial, medical, and consumer markets. The company's core products include active-matrix liquid crystal displays (CyberDisplay), liquid crystal on silicon, organic light-emitting diode, and micro light-emitting diode displays, along with application-specific optical subassemblies combining displays, optics, and electronics for rugged environments. Kopin generates revenue primarily through product sales to defense contractors and industrial customers, supplemented by customer-funded research and development contracts with U.S. government defense programs and licensing of reference designs; the company differentiates itself as the only U.S.-based small business offering five display technology variants and integrated subsystems rather than standalone components.
