FLUORESCENT CHARACTER DISPLAY TUBE DISPLAY PANEL PART WITH COLORED PHOSPHOR SCREEN, AND FLUORESCENT CHARACTER DISPLAY TUBE DISPLAY PANEL INCORPORATING THE PART

摘要

PROBLEM TO BE SOLVED: To provide a full color panel with high contrast at low cost, without changing a phosphor forming process by arranging in vacuum and forming a colored phosphor screen, which is excited by field accelerated incident electrons and emits fluorescence. ;SOLUTION: A colored phosphor screen is preferably formed by using a colored phosphor, a mixture of colored powder and a phosphor, or a coloring agent. An anode substrate is formed in such a way that a wiring pattern 2 is formed on a glass substrate, an insulating layer 4 is formed on the entire surface except for a through-hole 3, an anode electrode 5 is formed in the periphery, including the through-hole 3, and a phosphor layer 6 is formed on the anode electrode 5 by printing paste. The anode substrate is arranged together with a filament (a cathode) and a grid (an acceleration control electrode), and sealed airtightly within front glass. Voltage is applied to the filament with a transparent conductive film on the inside of the front glass.;COPYRIGHT: (C)1999,JPO
