    Abstract: Specified herein is a device which includes the use of a rod, or a filament, of light conducting material clad in a second light conducting material presenting a lower index of refraction than the core material but which is electrically controllable. The rod and cladding are supported in an electrode assembly by means of which the light conducting characteristics of the cladding is changed as a function of an electric field established by the electrode assembly so as to permit or prevent the passage of light through the rod. An information display panel embodiment of the invention is also disclosed utilizing a array of such devices.

    Abstract: Apparatus for controlling the formation and presentation of messages utilizing the high-speed light deflection characteristics of electro-optic light-refractive materials in combination with a longitudinally extended window of a lightlimiting member supported in the path of a light beam. The light beam is deflected vertically and allowed to enter the window whereby a series of vertically oriented side-by-side lines of light may be exposed to the surface of a display medium. But, in the process of doing so, the light beam will be deflected horizontally and beyond the limits of the window so as to effect interruptions in lines of the series which correspond to the formation requirements of a message being presented.
