Paper Abstract

A display system has been developed which is capable of full 2048 X 2048 pixel resolution with an eight-bit gray scale. An essential element of this system is a multibeam cathode ray tube (CRT), which enables the flicker-free display of 4,000,000 picture elements without the penalty of unmanageable video and deflection frequencies. Such a tube has been found to deliver 15-20 ft-Lamberts brightness with actual tube resolution somewhat in excess of the requirement above, over a 10 inch square raster. This paper describes the tube, its electron optics, and performance.
