Abstract

La presente invención se refiee a un cinescopio de color que incluye unas mascarillas de sobra montada adyacente a una pantalla de línea incluyendo la mascarilla de sombra una pluralidad de aberturas en forma de ranura situadas en columnas, teniendo la patalla de línea una periferia sustancialmente rectangular con dos lados largos opuestos y dos lados cortos opuestos, un eje mayor (X-X) de dicha pantalla que es un eje que pasa a través del centro de la pantalla y se extiende centralmente a través de los lados cortos, y un eje menor (Y-Y) de la pantalla que es un eje que pasa a través de los lados largos; incluyendo la pantalla las líneas catodoluminiscentes que se extienden generalmente en la misma dirección que el eje menor; caracterizado porque las líneas de material catodoluminiscente de la pantalla, en vista en planta frontal, aumentan primero en curvatura al aumentar la distancia desde el eje menor, y luego disminuyen curvatura con un aumento adicional en la distancia del eje menor, para volverse sustancialmente rectas en los lados cortos de la pantalla, la curvatura de las líneas catodoluminiscentes siendo cóncava mirando al eje menor de la pantalla.
