Abstract
A cathode ray tube suitable for use as a visual display includes two or more electron guns. The beams from the electron guns are aligned vertically so that a single horizontal scan of the guns produces two rows of pixels on the front face of the tube. This allows twice as much data to be painted on the display screen without increasing the scan rate of the electron guns. Each of the guns may be a single beam gun, for monochrome displays, or each may be a triple-element gun for RGB displays.
