An eight-segment display is a type of display based on eight segments that can be turned on or off according to the font pattern to be produced.
It is similar to a nine-segment display whose middle vertical bars are vertical, except that on an eight-segment display, the bars F and G are merged.
Applications
It was used, for instance, in the calculator Sharp EL-8, producing more rounded digits than a seven-segment display, but fewer possible digits it can display because the bars 'F' and 'G' are merged (see table below).
Displaying
An eight segment display can sometimes display characters with less readability because the segments F and G are combined and the corners are rounded. It is unable to display the following characters for this reason:
