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.
A Nixie tube (English: / ˈ n ɪ k. s iː / NIK-see), or cold cathode display, [1] is an electronic device used for displaying numerals or other information using glow discharge. The glass tube contains a wire-mesh anode and multiple cathodes, shaped like numerals or other symbols.
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.
The 1967 Japanese single digit seven segment display in terms of anode was more like the Philips DM70 / DM71 Magic Eye as the DM160 has a spiral wire anode. The Japanese seven segment VFD meant that no patent royalties needed to be paid on desk calculator displays as would have been the case using Nixie tubes or Panaplex neon digits or for LED ...

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] A slight variation is ...
The following phrases come from a portable media player's seven-segment display. They give a good illustration of an application where a seven-segment display may be sufficient for displaying letters, since the relevant messages are neither critical nor in any significant risk of being misunderstood, much due to the limited number and rigid domain specificity of the messages.
