Abstract

Un tubo de imagen a color mejorado incluye una envoltura de vidrio vacío que tiene un panel de placa superficial rectangular. El panel incluye un ensamblaje de máscara de sombra montada en el mismo. El ensamble de máscara de sombra incluye una máscara de sombra formada de un primer metal que tiene un primer coeficiente de expansion térmica, y un marco formado de un segundo metal que tiene un segundo coeficiente de expansion térmica. El primer coeficiente de expansion térmica es sustancialmente más bajo que el segundo coeficiente de expansion térmica. La mejora comprende la interconexion de la máscara de sombra con el marco mediante una pluralidad de elementos bimetálicos, teniendo cada uno de los elementos un primer extremo unido al marco y un segundo extremo unido a la máscara. Cada elemento bimetálico está formado de materiales que causan un doblamiento del elemento una cantidad relacionada con la expansion térmica del marco.
