Abstract
La presente invencion se refiere a un tubo de rayos catodicos a color (10) que tiene una envoltura evacuada (11) con una pistola de electrones (26) en el mismo, para generar cuando menos un haz de electrones (28). La envoltura (11) incluye además un panel de placa de cara (12) que tiene una pantalla luminiscente (22) con líneas de fosforo sobre una superficie interna del mismo. Una máscara de enfoque de tension uniaxial (25), que tiene una pluralidad de primeros cordones de metal separados (40) se localiza adyacente a un área de imagen efectiva de la pantalla. La separacion entre los primeros cordones de metal define una pluralidad de ranuras (42) sustancialmente paralelas a las líneas de fosforo de la pantalla. Cada uno de los primeros cordones de metal a través del área de la imagen efectiva de la pantalla, tiene una primera capa aislante sustancialmente continua (64) sobre un lado que da hacia la pantalla de los mismos. Una segunda capa aislante (66) se sobrepone a la primera capa aislante. Una pluralidad de segundos cordones de metal (60) se orientan sustancialmente perpendiculares a los primeros cordones de metal, y se enlazan a los mismos mediante la segunda capa aislante. La primera capa aislante tiene un coeficiente de espansion térmica que concuerda sustancialmente con, o es ligeramente más bajo que, aquel de los primeros cordones. La segunda capa aislante tiene un coeficiente de expansion térmica que es sustancialmente idéntico a aquel de la primera capa aislante.
