The LED variant is typically manufactured in single or dual character packages, to be combined as needed into text line displays of a suitable length for the application in question they can also be stacked to build multiline displays.Īs with seven and fourteen-segment displays, a decimal point and/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. Sixteen-segment displays may be based on one of several technologies, the three most common optoelectronics types being LED, LCD and VFD. Later they were used on videocassette recorders (VCR), DVD players, microwave ovens, car stereos, telephone Caller ID displays, and slot machines. īefore the advent of inexpensive dot-matrix displays, sixteen and fourteen-segment displays were used to produce alphanumeric characters on calculators and other embedded systems. Non-electronic displays using this pattern existed as early as 1902.

Later they were used to display Thai numerals and Persian characters. Sixteen-segment displays were originally designed to display alphanumeric characters (Latin letters and Arabic digits). Often a character generator is used to translate 7-bit ASCII character codes to the 16 bits that indicate which of the 16 segments to turn on or off. Other variants include the fourteen-segment display which does not split the top or bottom horizontal segments, and the twenty-two-segment display that allows lower-case characters with descenders. 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. Arabic numerals and letters of the ISO basic Latin alphabet on a typical 16-segment displayĪ sixteen-segment display ( SISD) is a type of display based on sixteen segments that can be turned on or off to produce a graphic pattern.
