Grating Light Valve (GLV) is a technology that works on the principal of dynamic adjustable diffration grating. Pixels are created from ribbon like structures on a silicon wafer. These structures are held under tension over a thin air gap and are allowed to move vertically. Deflection of the ribbons causes diffraction of incident light and controlling the ratio of diffraction to reflection is what makes GLV suitable for applications such as imaging, displays and projection. GLV was first discovered at Stanford University in California. The inventors named the company Silicon Light Machines to further develop and commercialize the technology. This company was later bought by Dainippon Screen Manufacturing Co., Ltd. and now is a wholly owned by the latter.
