Fourteen-segment display

A fourteen-segment display (FSD) (sometimes referred to as a starburst display or Union Jack 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 more common <a href="/facts/Seven-segment_display/4rzfu0q0">seven-segment display</a>, 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 <a href="/facts/ISO_basic_Latin_alphabet/DxrvCBK8">ISO basic Latin alphabet</a> requires more detail. A slight variation is the <a href="/facts/Sixteen-segment_display/n3EtQ5rv">sixteen-segment display</a> which allows additional legibility in displaying letters or other symbols.
A <a href="/facts/Decimal_point/t6ocVouk">decimal point</a> or <a href="/facts/Comma/mcW9dcGT">comma</a> may be present as an additional segment, or pair of segments; the comma (used for triple-digit groupings or as a <a href="/facts/Decimal_separator/t6ocVouk">decimal separator</a> 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 <a href="/facts/Light-emitting_diode/gE8x4MDb">LEDs</a>, <a href="/facts/Liquid_crystal_display/8B6xGBEz">LCDs</a>, or <a href="/facts/Vacuum_fluorescent_display/70BmkStl">vacuum fluorescent display</a> 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 <a href="/facts/Character_generator/yy0w2FAt">character generator</a> 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.
