Abstract

La presente invención se refiere a mejoras en método para la preparación de una estructura de pantalla para un tubo de rayos catódicos, que comprende un papel de placa frontal que incluye una ventana de presentación, estando la pantalla en la superficie interior de la ventana, y un conjunto de máscara perforadora separada de la ventana y mienbros de soporte de compensación de temperatura para montar el conjunto en el panel; comprendiendo el método las etapas de recubrir la superficie interior de la ventana con una capa que incluye un material endurecible a la luz; calentar el panel a temperaturas superiores a 50°C, con el fin de secar el recubrimiento; montar el conjunto de máscara en el panel calentado, estando el conjunto aproximadamente a la temperatura ambiente; y luego, antes de que el panel se haya enfriado por debajo de los 40°C, exponer la capa a la luz proyectada a través de la máscara; caracterizadas por enfriar los miembros de soporte para proporcionar un espacio deseado entre las máscaras y la superficie interior de la ventana.
