ABSTRACT:
A raster-type personal display is provided by vibrating an array of fiber optic filaments (32) between display limit (52, 54) by means of an electromechanical exciter (36). One end of the fiber optic filaments (32) is cantilever mounted to an array of light emitting diodes (34), with the second end of the filaments free to be vibrated by the exciter (36). Drive signals for energizing the light emitting diodes (34) are generated by a symbol generator (38) that receives synchronization pulses from a position detector consisting of a light source (58), a shutter (56) and a light responsive pickup (60).
