Concept and visual structure[ edit ] The individual segments of a seven-segment display 16x8-grid showing the states of a seven-segment display The common segment displays shown side by side: 7-segment, 9-segment , segment and segment displays. The seven elements of the display can be lit in different combinations to represent the Arabic numerals. Often the seven segments are arranged in an oblique slanted arrangement, which aids readability. The numerals 6 and 9 may be represented by two different glyphs on seven-segment displays, with or without a 'tail'. Additionally, the seventh segment bisects the rectangle horizontally. There are also fourteen-segment displays and sixteen-segment displays for full alphanumerics ; however, these have mostly been replaced by dot matrix displays. Twenty-two segment displays capable of displaying the full ASCII character set [5] were briefly available in the early s, but did not prove popular. The segments of a 7-segment display are referred to by the letters A to G, where the optional decimal point an "eighth segment", referred to as DP is used for the display of non-integer numbers. Numitron A mechanical seven-segment display for displaying automotive fuel prices Typical pinout of a common cathode electronic seven-segment display. Seven-segment displays may use a liquid crystal display LCD , a light-emitting diode LED for each segment, an electrochromic display , or other light-generating or controlling techniques such as cold cathode gas discharge Panaplex , vacuum fluorescent , incandescent filaments Numitron , and others. For gasoline price totems and other large signs, vane displays made up of electromagnetically flipped light-reflecting segments or "vanes" are still commonly used. An alternative to the 7-segment display in the s through the s was the cold-cathode, neon-lamp-like nixie tube. Starting in , RCA sold a display device known as the Numitron that used incandescent filaments arranged into a seven-segment display. Integrated displays also exist, with single or multiple digits.

Joshua Mamouney. For example, all the anodes of the A segments of each digit position would be connected together and to a driver circuit pin, while the cathodes of all segments for each digit would be connected. To operate any particular segment of any digit, the controlling integrated circuit would turn on the cathode driver for the selected digit, and the anode drivers for the desired segments; then after a short blanking interval the next digit would be selected and new segments lit, in a sequential fashion.

In this manner an eight digit display with seven segments and a decimal point would require only 8 cathode drivers and 8 anode drivers, instead of sixty-four drivers and IC pins.

Although to a naked eye all digits of an LED display appear lit, the implementation of a typical multiplexed display described above means that in reality only a single digit is lit at any given time.

A single byte can encode the full state of a 7-segment-display. The most popular bit encodings are gfedcba and abcdefg, where each letter represents a particular segment in the display. In the gfedcba representation, a byte value of 0x06 would in a common anode circuit turn on segments 'c' and 'b', which would display a '1'. History[ edit ] Seven-segment representation of figures can be found in patents as early as in U.
