What is the nine segment display?

The nine segment display is by far the rarest and least used of the four display types supported in library. There are a few variants of it. Only 1 and 2 are commercially available at present as far as I know. The font included supports number one only, as it most common and defined.

What characters are covered by the LED display segment library?

The library is hosted on GitHub and has symbols for 16-segment, 14-segment, and 7-segment LED displays. All visible ASCII characters are covered (32 – 127 inclusive). Both binary and hexadecimal literals are included depending on your application, as well as images of the characters and a display segment legend.

What is a 14 segment LCD display?

LCD fourteen-segment display as used on Hewlett-Packard’s HP-41 range of programmable engineering calculators from the late 1970s. 14 segment LCD as used on the Hewlett-Packard HP3478A Multimeter. LCD fourteen-segment characters on an after-market car stereo.

Are the letters in a nine-segment display uppercase or lowercase?

The letters displayed by a nine-segment display are not consistently uppercase or lowercase in shape. A common compromise is to use a lower-case “n” instead of “N”. Depending on the design of the display segments, the use of the extra two segments may be avoided whenever possible, as in the Nixxo X-Page “tall” lowercase “r” and “y”.
