Segmented liquid-crystal display

A segmented liquid-crystal display (segmented LCD) is a type of liquid-crystal display commonly used for showing numerical or limited character information, primarily in devices like calculators and digital watches.

Segmented LCDs often display information in a one-line format. They can have 7-segment digits, or 14- or 16-segment characters. Segments can be arbitrary shapes and sizes.

Segmented LCDs were built into the Game & Watch series of handheld electronic games.

HP produced segmented LCDs for the HP-41C series of calculators.

8- and 16-segment LCDs are made as a stack of two glass sheets, each patterned with transparent electrodes, typically using indium tin oxide (ITO). Liquid crystal is filled between the two sheets. Typically, the rear glass is all one common electrode.

The first liquid crystal display was developed by a team of engineers led by George Heilmeier.
