Design, fabrication, and performance of a flat tube display

Abstract

A thin profile (two-inch depth) digitally addressed cathodoluminescent display has been developed which is capable of presenting 1920 alphanumeric 5 × 9 dot matrix characters at a spot brightness of 500 ft-L. Multilevel addressing techniques permit greatly reduced pinout (108 addressing levels for the A/N display versus 590 levels on equivalent plasma matrix display). Gray scale is achievable by pulse width modulation, and color is achievable by using a patterned phosphor faceplate.
