Abstract

EL METODO DE FABRICAR ELECTROFOTOGRAFICAMENTE UN CONJUNTO DE PANTALLA (22) SOBRE UN SUBSTRATO (18) PARA USO DENTRO DE UN CRT (10), DE ACUERDO AL INVENTO ACTUAL, INCLUYE LAS ETAPAS DE RECUBRIR SECUENCIALMENTE UN SUBSTRATO CON UNA CAPA CONDUCTORA (32) Y UNA SOBRECUBIERTA DE UNA CAPA FOTOCONDUCTORA (34), ESTABLECIENDO UNA CARGA ELECTROSTATICA SOBRE LA CAPA FOTOCONDUCTORA, Y EXPOSICION DE LAS AREAS SELECCIONADAS DE LA CAPA FOTOCONDUCTORA A LA LUZ VISIBLE PARA AFECTAR LA CARGA DE LA MISMA. ENTONCES LA CAPA FOTOCONDUCTORA SE DESARROLLA CON UN MATERIAL DE ESTRUCTURA DE PANTALLA CARGADA. EL PROCESO MEJORADO UTILIZA UN MATERIAL DE ESTRUCTURA DE PANTALLA PULVERIZADA EN SECO QUE TIENE AL MENOS UN AGENTE DE CONTROL DE CARGA DE SUPERFICIE EN LA MISMA PARA CONTROLAR LA CARGA TRIBOELECTRICA DEL MATERIAL DE LA ESTRUCTURA DE LA PANTALLA.
