Abstract
An alphanumeric display system including an array of sixteen electrically energizable, light-emitting elements capable, when selectively energized, of forming legibly all numerals and a substantial number of upper and lower case alphabet letters and/or mathematical and punctuation symbols. A similar array is disclosed having a maximum of twenty four light-emitting elements and capable of providing all numerals, upper and lower case alphabet letters and a majority of the symbols employed for punctuation and in mathematics. Both of the arrays disclosed are characterized by arrangement of the light-emitting elements in closely nested relation to form horizontal rows and columns inclined to the right and left at 60.degree. with respect to the horizontal. A solid state system including light-emitting diodes and switching transistors is disclosed. PAC ALPHANUMERIC DISPLAY SYSTEM
