However, this modern scheme was not always followed in the past, and various other schemes could be found as well. One such special case is the display of the letters A-F when denoting the hexadecimal values digits 10- These are needed on some scientific calculators, and are used with some testing displays on electronic equipment.ДЄlthough there is no official standard, today most devices displaying hex digits use the unique forms shown to the right: uppercase A, lowercase b, uppercase C, lowercase d, uppercase E and F. In addition to the ten digits, seven-segment displays can be used to show most letters of the LatinCyrillic and Greek alphabets including punctuation. CDEG is occasionally encountered on older calculators to represent 0. Two basic conventions are in common use for some Arabic numerals : display segment A is optional for digit 6, segment F for 7, and segment D for 9. Such representation of characters is not standardized by any relevant entity e. Wikimedia Commons has media related to Category:Sixteen segment displays.The topic of seven-segment display character representations revolves around the various shapes of numerical digitslettersand punctuation devisable on seven-segment displays.

This way, a point or comma may be displayed between character positions instead of occupying a whole position by itself, which would be the case if employing the bottom middle vertical segment as a point and the bottom left diagonal segment as a comma. 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.ДЄs 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. However, they are still sometimes used on VCRs, car stereos, microwave ovens, telephone Caller ID displays, and slot machine readouts. Д«efore the advent of inexpensive dot-matrix displays, sixteen and fourteen-segment displays were some of the few options available for producing 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).
