A light valve is a specialized LCD that works like the shutter in a camera. When the display is off it will allow light to pass through and will block light when turned on. Light valves are used in telecommunications equipment (especially fiber-optics) as well as test equipment that measures light and/or opacity. Excel Display manufactures several kinds of light valves incorporating TN, Pi-Cell, and PDLCD technology. The simplest light valves will have a single segment to control light passage, more complex light valves with multiple aperatures in various configurations are available.
