Abstract

Le film en aluminium couvrant l'écran image adhère esssentiellement au recouvrement absorbant la lumière, qui, à cet effet, a une épaisseur supérieure d'au moins 3 mu m à celle des lignes luminescentes. L'invention permet d'obtenir, dans les tubes image en couleur du genre matrice, une image plus claire et plus égale Le recouvrement absorbant la lumière contient des grains dont 50 % en poids présentent de préférence un diamètre supérieur à 15 mu m. Application : tube télévision en couleur.
