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:
