A eight-segment display is a type of display based on eight segments that can be turned on or off according to the graphic pattern to be produced. It is an extension of the more common seven. segment-display, having one additional segment.
Designs[]
- Pictured to the left is the design based on the conventional seven-segment display, with one additional horizontal segment overlapping the middle segment. This design is mainly used in calculators, as in addition to numbers, the plus (g h) and minus (g) signs are displayed as well.
- Sharp EL-8 calculators use their unique eight-segment display, which is unlike the usual seven-segment display. The display in general resembles a vertical line (made with 2 segments) through an 8-shape (in 6 segments). The vertical line is mainly used for numbers made exclusively with straight lines such as 1 and 4.
- The original eight-segment display by Frank W. Wood, as seen in his 1908 patent, used one additional diagonal segment within the top counter of the conventional seven-segment display, which was used for better-shaped numbers such as 4 or 7.
- Some elevator floor display screens have their own eight-segment display, similar to the regular seven-segment display, except that the middle segment is split into two. This can be used for letter G (ground floor).
- On Flickr, Adam Sporka created his own eight-segment display design styled like either Japanese kana or Art Nouveau. This design can either be round or square, and can provide an efficient method of displaying alphanumeric characters.
- Posy created his own eight-segment display, which he called "X Ugly", although his guide of his own segment displays 9 segment collection erroneously refers to it as a . This design features an X-shape made of four segments within a square frame of another four segments. According to Posy, it provides an efficient method of displaying alphanumeric characters. The vertical segments can be used for a better 1 or 0 as opposed to most other designs in Posy's "X" display family. Some letters on the display may have alternatives depending on the form of upper or lower case, such as B, C, E, G, N, Q, and R. It is based on the eight-segment IEL display originally from Russia. The design pictured to the right is based off this.
