In a simple LED package, typically all of the cathodes (negative terminals) or all of the anodes (positive terminals) of the segment LEDs are connected and brought out to a common pin; this is referred to as a "common cathode" or "common anode" device. [16] Hence a 7 segment plus decimal point package will only require nine pins, though ...
The individual segments of a seven-segment display. The various shapes of numerical digits, letters, and punctuation on seven-segment displays is not standardized by any relevant entity (e.g. ISO, IEEE or IEC). Unicode provides encoding codepoint for segmented digits in Unicode 13.0 in Symbols for Legacy Computing block.
Typically, 7-segment displays are made to have a common cathode, sometimes a common anode, but without loss of generality a common cathode is assumed in the following: All LEDs in all 8 7-segment displays cannot be turned on simultaneously in any desired combination using Charlieplexing.
One such arrangement is 6 7 5 8 4 3 9 2 0 1 from front (6) to back (1). [10] [11] Russian ИH-12A (IN-12A) and ИH-12B (IN-12B) tubes use the number arrangement 3 8 9 4 0 5 7 2 6 1 from front (3) to back (1), with the 5 being an upside down 2. The ИH-12B tubes feature a bottom far left decimal point between the numbers 8 and 3.
In practice, there is little limit to the shape of the image that can be displayed: it depends solely on the shape of phosphor on the anode(s). The first VFD was the single indication DM160 by Philips in 1959. [5] The first multi-segment VFD was a 1967 Japanese single-digit, seven-segment device made by Ise Electronics Corporation. [6]

It is an expansion of the more common seven-segment display, having an additional four diagonal and two vertical segments with the middle horizontal segment broken in half. A seven-segment display suffices for numerals and certain letters, but unambiguously rendering the ISO basic Latin alphabet requires more detail. [3]
