Abstract

Dispositif d'affichage plat qui comprend : une enveloppe mise sous vide comportant des parois frontale et postérieure sensiblement plates, parallèles et espacées l'une de l'autre et des parois de support sensiblement parallèles et espacées s'étendant entre les parois postérieure et frontale en étant sensiblement perpendiculaire à ces parois, lesdites parois de Support divisant l'enveloppe en une pluralité de canaux; des moyens à une extrémité de chacun desdits canaux pour engendrer des électrons et les diriger sous le forme de faisceaux dans lesdits canaux, trois faisceaux étant dirigés dans chacun des canaux; des guides de faisceau le long de chacun desdits canaux pour confiner les électrons dans le faisceau lorsque les faisceaux circulent longitudinalement le long du canal et pour dévier sélectivement les faisceaux vers un écran de phosphore sur la paroi frontale de l'enveloppe en des points choisis le long des canaux et des moyens dans chaque canal entre les guides de faisceaux et l'écran de phosphore pour dévier les faisceaux transversalement au canal de telle façon que ces faisceaux balaient l'écran de phosphore, ce dispositif d'affichage étant caractérisé en ce qu'il comporte des moyens dans chaque canal pour engendrer un champ électrostatique, transversalement au canal, qui agit comme une lentille électronique pour faire convertir les trois faisceaux en un point propre, mais cependant espacé de l'écran de phosphore.
