Abstract

An alphanumeric display including an array of 42 electrically energizable, light-emitting or reflecting segments which, when selectively energized, are capable of forming legibly all numerals and upper and lower case alphabet letters and/or mathematical and punctuation symbols. The array disclosed is characterized by arrangement of the light-emitting or reflecting elements in closely nested relation to form a vertically disposed rectangular display. A solid state system employing the display means including light-emitting diodes and switching transistors is disclosed.

Claims

1. An alphanumeric display system for displaying the Russian and English languates comprising in combination;

an array of 42 electrically energizeable elements, which elements are arranged in a generally vertically oriented rectangular array with appendages thereto, said array consisting of six generally rectangular zones arranged in two equal vertical columns of said zones,

said array'"'"'s six zones each having spaced horizontal and spaced vertical boundary elements, and said array'"'"'s six zones each having at least one linear, angularly disposed element within each zone, said array being energizable in selected combinations to form all of the numerals, letters and other symbols of said languages.

2. The display system of claim 1 wherein the six zones are designated upper left, upper right, middle left, middle right, lower left and lower right.

3. The display as in claim 1 wherein the plurality of elements include elements some of which are linear and others of which are circular.

4. The display as in claim 1 wherein the elements include linearly configured elements, some of which are disposed generally horizontally and some of which are disposed generally vertically.

5. The display of claim 1 wherein the symbols include both mathematical and punctuation symbols.

6. A display system as defined in claim 1 further including means for energizing selected combinations of the elements to form numerals, letters, and other symbols.

7. The display system of claim 1 wherein a plurality of at least two of the arrays are disposed adjacent to each other to permit the formation of words and multi digit numerals.

8. The display system of claim 7 further including means for energizing selected combinations of the elements to form numerals, letters and other symbols.

9. The display system of claim 1 wherein one element is a vertical linear element spaced above the center line between the right column and left column of the display.

10. The display system of claim 1 wherein the display includes a pair of parallel elements inclined downwardly and leftwardly, spaced from the lower right corner of the display, and from the midpoint along the bottom of the display respectively.

11. An alphanumeric display system for displaying the Russian and English languages comprising in combination;

an array of 42 electrically energizeable elements, which elements are arranged in a generally vertically oriented rectangular array with appendages thereto, which array consists of six generally rectangular zones arranged in two equal vertical columns of said zones, namely a left column and a right column, with a center line therebetween,

said array'"'"'s six zones each having spaced horizontal and spaced vertical boundary elements, and said array'"'"'s six zones each having at least one linear, angularly disposed element within each zone,

further including as an appendage to the rectangular array a vertical linear element spaced above the center line between the right column and left column of the display, and also as appendages a pair of parallel elements inclined downwardly and leftwardly, spaced from the lower right corner of the display, and from the midpoint along the bottom of the display respectively, said array and appendages being energizable in selected combinations to form all of the numerals, letters, and other symbols of said languages.
