One application was in the Sharp EL-8, an early electronic calculator.The eight-segment display produces more rounded digits than a seven-segment display, yielding a more "script-like" output, with the trade-off that fewer possible alphabetic characters can be displayed because the bars F and G are merged (see table below).
In the following Arduino code example, the circuit [38] [39] uses ATtiny 8-pin microcontroller which has 5 I/O pins to create a 7-segment display. Since a 7-segment display only requires control of 7 individual LEDs, we use 4 of the ATtiny I/O pins as Charlieplexed outputs (n (n - 1)), i.e. the 4 pins could be used to control up to 12 ...
Became a nearly ubiquitous analog computer display connector after first being introduced with IBM x86 machines. Older VGA connectors were DE-9 (9-pin). The modern DE-15 connector can carry Display Data Channel to allow the monitor to communicate with the graphics card, and optionally vice versa. [1] Being replaced by DVI from 1999 onward. DB13W3

A seven-segment display is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays. Seven-segment displays are widely used in digital clocks , electronic meters, basic calculators, and other electronic devices that display numerical information.
Previous version erroniously showed pin 4 illuminating the lower-left segment. This has been corected, to show that pin 4 illuminates the lower-right segment. 22:58, 13 May 2016: 222 × 525 (30 KB) Avh.on1: User created page with UploadWizard
