light valve

With respect to display systems, a device that uses an independent light source and a control-layer medium, the active optical element, to convert an electrical charge image to an optical image. Electrical energy, usually generated by an electron beam, changes the optical properties of the medium and controls the transfer of light flux from the source, relative to the applied electrical energy.
