Abstract
An alphanumeric display system including an array of preferably 14 or alternatively, 15 light-emitting elements capable, when selectively activated, of legibly forming all numerals, and various alphabet letters and/or mathematical and punctuation symbols. The arrays disclosed are characterized by the arrangement of the light-emitting elements in a closely nested relation to form horizontal rows and columns inclined to both the right and the left at 60° with respect to the horizontal. A solid state system for selectively energizing the light-emitting elements is disclosed.
