Abstract
A display has a cathode ray tube (CRT) provided with a multiplicity of electron beams or beam sets. Each of the beams has its own auxiliary beam control assembly including deflection means. Each beam assembly is directed to energize a prescribed portion of the display format area. The typical application may employ two to six beam sets and is useful to reduce total depth and bulk of CRT's having high aspect ratios and/or large size. The displayed area shows substantially no visible boundaries (tiling) between portions.
Claims16
A color CRT display comprising:
- a display surface comprising a continuous phosphor screen for generating a visible image in response to impingement by an electron beam;
- a plurality of beam generation assemblies for generating and deflecting a plurality of electron beams for impingement on respective contiguous areas of said continuous phosphor screen;
- and
- signal means for providing input signals to each of said beam generation means for controlling the motion of each electron beam over its respective area to produce a unified visible image, wherein said phosphor screen comprises a pattern of triads of primary colors and said signal means comprises means for providing dynamic color separation.
