摘要：An addressing circuit arrangement for an electrical display device comprising atwo-dimensional matrix of light-emitting elements which are connected at respectivecrosspoints formed by two groups of row and column conductors and each of which canbe illuminated selectively by suitable energizing signals applied contemporaneously tothe two conductors, one in each group, between which the element is connected. Thearrangement includes, a circulation memory for storing character data in respect of aplurality of lines of characters to be displayed and for supplying in turn the characterdata for each line of characters serially character by character in a recurrent cycle, acharacter generator which is responsive to the supplied data for each character toproduce a group of coded electrical signals that determine the discrete parts of thecharacter to be displayed in the row of elements concerned, and a row store for storingin each fill period of each row period the several groups of coded electrical signals forthe whole of the row of elements concerned.
