ABSTRACT:
A lightweight fiber optic television display useful for front and rear projection systems. An array of pixels such as a fiber optic (FO) ribbon has an input end which receives input light illuminating the pixels so as to create a first dimension of the display. The output end of the FO ribbon is moved relative to the observer to create a second dimension. The FO ribbon is clamped by a clamp near the output end and vibrated by a driver so that the output end of the ribbon is moved to obtain the second dimension. A lens is disposed between the vibrating end of the FO ribbon and a projection screen, and images the two dimensional image formed by the vibrating output end of the ribbon onto the screen. The projection screen may be either a rear or front projection screen. The FO ribbon may include a single row of fibers, or multiple rows to improve the image quality.
