High Quality Content by WIKIPEDIA articles! 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. A seven-segment display suffices for numerals and certain letters, but to unambiguously render the roman alphabet requires more detail. It is an extension of the more common seven-segment display, having an additional four diagonal and two vertical segments with the middle horizontal segment broken in half. The sixteen-segment display breaks all three horizontal segments in half. A decimal point and/or comma may be present as an additional segment, or pair of segments; the comma is commonly formed by combining the decimal point with a closely 'attached' leftwards-descending arc-shaped segment. Electronic alphanumeric displays may use LEDs, LCDs, 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.
