Abstract

DISPOSITIF D'AFFICHAGE ELECTROLUMINESCENT PAR TUBE A RAYONS CATHODIQUES A MEMOIRE, ET SON PROCEDE DE FONCTIONNEMENT. DANS CE SYSTEME, A VISUALISATION DIRECTE PAR TUBE CATHODIQUE 10 A MEMOIRE, ON UTILISE UN FAISCEAU ELECTRONIQUE 20, POUR ECRIRE ET EFFACER SELECTIVEMENT L'INFORMATION SUR UN PANNEAU ELECTROLUMINESCENT 16 A FILM MINCE QUI CONSTITUE LA CIBLE DU TUBE; L'ECRITURE ET L'EFFACEMENT DE L'INFORMATION S'EFFECTUENT EN ANALYSANT LE FAISCEAU SUR LA SURFACE ARRIERE DU PANNEAU, QUI EST CHOISIE DE FACON QU'ELLE POSSEDE UNE CARACTERISTIQUE DE MEMOIRE PROPRE, EN SYNCHRONISME AVEC UN TRAIN D'IMPULSIONS A POLARITES ALTERNEES QUI SONT APPLIQUEES AUX ELECTRODES AVANT ET ARRIERE; L'INFORMATION S'ECRIT SUR LE PANNEAU LORSQU'IL EST ADRESSE PAR LE FAISCEAU PENDANT L'APPLICATION D'UNE IMPULSION SOIT POSITIVE, SOIT NEGATIVE; L'EFFACEMENT SE PRODUIT QUAND LE PANNEAU EST ADRESSE DANS L'INTERVALLE QUI SUIT L'APPLICATION D'UNE IMPULSION POSITIVE A L'ELECTRODE ARRIERE. APPLICATION AUX TUBES A MEMOIRE POUR L'AFFICHAGE ET EFFACEMENT PARTIEL OU TOTAL D'INFORMATIONS.ELECTROLUMINESCENT DISPLAY DEVICE BY CATHODIC RAY TUBE WITH MEMORY, AND ITS OPERATING PROCEDURE. IN THIS SYSTEM, WITH DIRECT DISPLAY BY CATHODIC TUBE 10 WITH MEMORY, AN ELECTRONIC BEAM 20 IS USED, TO WRITE AND SELECTIVELY ERASE THE INFORMATION ON A THIN FILM ELECTROLUMINESCENT PANEL 16 WHICH CONSTITUTES THE TUBE TARGET; WRITING AND DELETING THE INFORMATION IS DONE BY ANALYZING THE BEAM ON THE REAR SURFACE OF THE PANEL, WHICH IS CHOSEN SO AS IT HAS A CHARACTERISTIC OF OWN MEMORY, IN SYNCHRONISM WITH A POLARITY PULSE TRAIN ALTERNATIVES WHICH ARE APPLIED TO THE FRONT AND REAR ELECTRODES; THE INFORMATION IS WRITTEN ON THE PANEL WHEN ADDRESSED BY THE BEAM DURING THE APPLICATION OF EITHER A POSITIVE OR NEGATIVE PULSE; DELETION OCCURS WHEN THE PANEL IS ADDRESSED IN THE INTERVAL FOLLOWING THE APPLICATION OF A POSITIVE PULSE TO THE REAR ELECTRODE. APPLICATION TO MEMORY TUBES FOR THE DISPLAY AND PARTIAL OR TOTAL DELETION OF INFORMATION.
