These Twelve-Digit Calculator Numeric Seven-Segment LED Displays are intended for use under pulsed conditions by enabling the common cathode of each digit sequentially and enabling the desired Segment anode in phase with the character enabling pulse. The pulse rate is kept high enough so that light from each character appears to the eye to be constant. The "G" segment of Digit 1 to Digit 6 is accessible on a separate terminal to allow its use as the minus sign of the Exponent for scientific calculators based on the TMS0100 family of single-chip calculator circuits.

The CP-200032 Twelve-Digit display assembly consists of a printed circuit board (PCB) with 2 TIL360 Multi-Digit displays and was introduced with the SR-10 Version 1. It was soon replaced with the DIS115E Twelve-Digit display assembly with 12 individual DIS279 Seven-Segment displays, improving with its increased spacing between the DIS279 elements and the integrated magnifying lens the readability of the 0.1”/2.54 mm characters significantly, while maintaining the mechanical dimensions of the CP-200032.

The displays are formed by soldering two TIL360 Multi-Digit Seven-Segment displays on a double-sided printed circuit board (PCB).

The CP-200032 uses a 2.65" / 67.5 mm by 0.87” / 22.0 mm rectangular printed circuit board (PCB) with 21 solder tabs with a 0.1” / 2.54 mm pitch arranged on the bottom of the display module.
