Zusammenfassung:A cursor sweeps the 16 character lines simultaneously addressed by a transmitted ASCII code. Two supplementary connections permit the shift of the cursor horizontally by unit of line in the vertical or column, permitting a X,Y positioning in some jumps. Over a zone non-frozen supplementary memory, of a size typical of 8x16 characters, it may receive a simple graph displayed according to the previous principle. Procédé d'adressage économique des pixels d'un écran LCD à bas coût remplaçant la connectique traditionnelle d'adressage directe lourde par un adressage semi-séquenciel au moyen d'un jeton circulant, moins rapide mais suffisant pour des applications de type Texte et semi-graphiques.
