Abstract

Le dispositif comprend un panneau récepteur 1 pour faire apparaître une image en fonction de niveaux électriques appliqués à des électrodes de rangée X et à des électrodes de colonne Y formant une matrice, un circuit de minutage 2, un circuit d'analyse 3 qui analyse les électrodes de rangée en synchronisme avec un signal de synchronisation horizontale, un générateur 4 qui engendre K (K supérieur ou égal à 2) signaux électriques différents de modulation de brillance entre un niveau minimal et un niveau maximal, un générateur 5 qui reçoit un signal d'image B et produit un signal de niveau de brillance, une mémoire de ligne 6 qui emmagasine le signal de niveau de brillance et le fournit en synchronisme avec le signal de synchronisation horizontale, et un circuit de sélection 7 qui sélectionne celui des K signaux de modulation de brillance qui correspond au signal de sortie de la mémoire de ligne, et qui l'applique aux électrodes de colonne du panneau récepteur. Récepteurs de télévision.
