Abstract

METODO DE DIRECCIONAMIENTO DE UN DISPOSITIVO DE REPRESENTACION VISUAL (2), QUE CONSTA DE UNA MATRIZ DE PUNTOS OPERABLES SEPARADAMENTE (6). EL PRIMER PASO ES LA APLICACION, A TRAVES DE UN PUNTO DADO, DE UNA FORMA DE ONDA DE TENSION CON UN PULSO DE BLOQUEO Y UN PULSO AUXILIAR DE MENOR AMPLITUD QUE EL PULSO DE BLOQUEO. LA AMPLITUD DEL PULSO AUXILIAR SE MODULA PARA LA DETERMINACION DEL EFECTO DE BLOQUEO DEL PULSO DE BLOQUEO.
