ABSTRACT Improvements to Information Display Devices A display device of the matrix type utilises coincident current selection of display elements by the provision of row conductors (R) activating row electro- magnets (D) and column conductors (C) activating column electromagnets (H). Each display element includes a rotatable vane (S) which is stable in open and closed positions and a permanent magnet (M) co-operates with the electromagnet (D) to urge the vane (S) into the appropriate position. Bar (L) extending from the vane (S) contacts the pole face of electromagnets (H) which, when activated, serves to inhibit movement of the vane irrespective of activation of the row electromagnet (D). Thus by pulsing the display row-by-row, the state of the display elements can be set by selective inhibiting of movement in coincident manner of the appropriate vanes (S) by pulsing the respective column conductors.
