MULTIPLE BEAM CATHODE RAY TUBE DESIGN OVERVIEW.

Abstract

A CRT which simultaneously writes 16 adjacent raster lines is described. The electron beams which write the lines are produced from very small electron guns fabricated on a single sapphire chip using thin-film techniques. Subsequently a single lens is used to focus the 16 beams on the screen and a conventional magnetic deflection yoke is used to deflect the beams to form the raster. Because the displayed data are handled in parallel, higher content flicker free images can be displayed.
