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.
