ABSTRACT:
A segment display wherein each segment is selectively energized to display, respectively, all numerals of the Arabian writing as distinguished from "arabic numbers". The segment display uses only seven or fewer segments for displaying all numbers by employing common use of segments for different numbers. The seven segment display readily adapts the display system to existing drive circuitry now used with seven segment displays for arabic numerals. The seven segment display enables the use of standard drive circuitry for control.
