Abstract
A display screen shows a number of alphanumeric characters in accordance with computer originating signals. These signals are fed to a liquid crystal panel which responsively vaires its opacity and, preferably, tapered fiber optics extend from one side of the liquid crystal panel to the screen. In one mode light originating from a high intensity source behind the screen is transmitted through the fiber optics. In another mode light from the front of the screen is reflected from a reflector surface behind the liquid crystal panel to the display screen. Either mode of operation allows the fabrication of a matrix of a number of liquid crystal panels and their associated fiber optics to provide an expanded display screen. Thus, an expanded visual presentation is read out from a computer or similar source of controlling signals to assure that several observers are reliably informed.
