Brief History
The light valve was originally developed at Stanford University, in California, by electrical engineering professor David M. Bloom, along with Raj Apte, Francisco Sandejas, and Olav Solgaard. In 1994, the start-up company Silicon Light Machines was founded by Bloom to develop and commercialize the technology. The company is now wholly owned by Dainippon Screen Manufacturing Co., Ltd.
In July 2000, Sony announced the signing of a technology licensing agreement with SLM for the implementation of GLV technology in laser projectors for large venues, but by 2004 Sony announced the SRX-R110 front projector using its own LCoS-based technology SXRD. SLM then partnered with Evans & Sutherland (E&S). Using GLV technology, E&S developed the E&S Laser Projector, designed for use in domes and planetariums. The E&S Laser Projector was incorporated into the Digistar 3 dome projection system.
