ABSTRACT:
A video display having a shutter assembly with apertures, optical guides extending behind the assembly and a group of different light sources channeling their light into each of the optical guides, respectively. The guides may be collimators which allow light to escape perpendicular to their front surfaces, which surfaces are located in back of the shutter assembly. The collimators have parabolic and hyperbolic mirrored surfaces facing each other within the collimator. Electronic control circuitry is provided to control the light outputs with a video input signal in relation to a horizontal sweep signal and to selectively make the shutter apertures transparent so as to expose a portion of the illuminated collimators in response to a vertical sweep signal. The intensity of the light source is varied to produce a high resolution, high speed video display.
