A '''fourteen-segment display''' (FSD) (sometimes referred to as a '''starburst display''' or '''Union Jack display'''<ref>{{cite web|title=AlphaNum G click with 14-segment LED display released|url=https://www.mikroe.com/blog/alphanum-g-click-with-14-segment-led-display-released|website=MikroElectronika Blog|publisher=MikroElektronika|access-date=11 March 2018}}</ref><ref>{{cite web|title=EFM32 Series 0 LCD Driver Application Note|url=https://www.silabs.com/documents/public/application-notes/an0057.0-efm32-segment-lcd.pdf|publisher=Silicon Laboratories|access-date=11 March 2018|page=11}}</ref>) is a type of display based on 14&nbsp;segments that can be turned on or off to produce letters and numerals. 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.<ref>Richard C. Dorf (ed.) ''The Electrical Engineering Handbook'', CRC Press, Boca Raton, 1993, {{ISBN|0-8493-0185-8}} page 1770</ref> A slight variation is the [[sixteen-segment display]] which allows additional legibility in displaying letters or other symbols.

A [[decimal point]] or [[comma]] may be present as an additional segment, or pair of segments; the comma (used for triple-digit groupings or as a [[decimal separator]] in many regions) is commonly formed by combining the decimal point with a closely 'attached' leftwards-descending arc-shaped segment.

Electronic alphanumeric displays may use [[light-emitting diode|LED]]s, [[liquid crystal display|LCD]]s, or [[vacuum fluorescent display]] devices. 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.

Often a [[character generator]] is used to translate 7-bit ASCII character codes to the 14 bits that indicate which of the 14 segments to turn on or off.<ref>
