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

Segmented LCDs often display information in a one-line format.^[1] They can have 7-segment digits, or 14- or 16-segment characters.^[2]

Segmented LCDs were built into the Game & Watch series of handheld electronic games.^[3]

HP produced segmented LCDs for the HP-41C series of calculators.^[4]

Construction

8- and 16-segment LCDs are made as a stack of two glass sheets, each patterned with transparent electrodes, typically using indium tin oxide. Liquid crystal is filled between the two sheets. Typically, the rear glass is all one common electrode.^[5]
