Abstract
A CRT that simultaneously writes 16 adjacent raster lines is described. The electron beams that 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 is handled in parallel, higher content flicker-free images can be displayed. The dynamic corrections required to achieve display contents above 10 Mpixel are discussed.
