Seven-segment display (SSD):
A seven-segment display (SSD), or seven-segment indicator, is a electronic display device for displaying decimal numerals. Seven-segment displays are widely used in digital clocks, electronic meters, and other electronic devices for displaying numerical information.

Vane display:
A vane display is a type of 7-segment display. Unlike LED segmented displays, vane displays are composed of seven physical
surfaces, typically painted white, but occasionally other colors, such
as yellow or fluorescent green. If a segment is to be displayed as
"off", it will be rotated so that its edge faces forward, with the
painted surface pointing away and not visible. A segment that is to be
displayed as "on" will be rotated so that the painted surface is shown.

Nine-segment display:
A nine-segment display is a type of display based on 9 segments
that can be turned on or off according to the graphic pattern to be
produced. It is an extension of the more common seven-segment display,
having an additional two diagonal or vertical segments between the top,
middle, and bottom horizontal segments. This provides a minimal method
of displaying alphanumeric characters. Basically developed for Russian Scientific Calculator.

Fourteen-segment display:
A fourteen-segment display is a type of display based on 14 segments that can be turned on or off
to produce letters and numerals. It is an expansion of the 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. A slight variation is the sixteen-segment display which allows additional legibility in displaying letters or other symbols.

Nixie tube:
A Nixie tube is an electronic device 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. Applying power to one cathode surrounds it with an orange glow discharge. The tube is filled with a gas at low pressure, usually mostly neon and often a little mercury or argon, in a Penning mixture.

Sixteen-segment display:
A sixteen-segment display, is a type of display based on 16 segments that can be turned on or off
according to the graphic pattern to be produced. It is an extension of
the more common seven-segment display, adding four diagonal and two vertical segments and splitting the three horizontal segments in half (A fourteen-segment display splits only the middle horizontal segment). Sixteen-segment displays were originally designed to display alphanumeric character.
