LCD 'fourteen-segment display' as used on Hewlett-Packard's
HP-41 range of programmable engineering calculators of the
1980s.
A 'fourteen-segment display' (sometimes referred to as a 'starburst display' or a "Union Jack" display) is a type of display based on 14 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 four diagonal and two vertical segments with one horizontal segment broken in half. The
sixteen-segment display breaks the other two horizontal segments in half.

Before the advent of inexpensive
dot-matrix displays, fourteen and
sixteen-segment displays were some of the few options available for producing
alphanumeric characters on
calculators and other
embedded systems. Applications today include displays fitted to
car stereo, telephone
Caller ID units, gymnasium equipment and DVD players.

A fourteen-segment display may be based on one of several technologies, the most common being
optoelectronic ones such as
LED and
LCD technology. The LED variant is typically manufactured in single or dual character packages, allowing the system designer to choose the number of characters suiting the application.
Fourteen-segment
gas-plasma displays were used in
pinball machines from 1986 through 1991 with an additional
comma and
period part making for a total of 16 segments.
