Abstract (en)
A sign having rows and columns of selectively illuminable incandescent globes (15) in which each row is located so as to be seen only through an associated aperture (14) in the face of the sign. Mechanically the electronic circuitry associated with the sign may comprise two spaced circuit boards (21, 25), the spacing being provided by certain of the components (26). The time of display of messages on the sign can be varied depending upon the cognative latency of the particular message being displayed.
