Segment LCD
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. __TOC__ 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, indium tin oxide (ITO). Liquid crystal is filled between the two sheets. Typically, the rear glass is all one common electrode. Layers History The first liquid crystal display was developed by a team of engineers led by George Heilmeier. References {{improve categories, date=Jan ...

A liquid-crystal display (LCD) is a flat-panel display or other Electro-optic modulator, electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers to display information. Liquid crystals do not emit light directly but instead use a backlight or Reflector (photography), reflector to produce images in color or Monochrome monitor, monochrome. LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images with low information content, which can be displayed or hidden: preset words, digits, and seven-segment displays (as in a digital clock) are all examples of devices with these displays. They use the same basic technology, except that arbitrary images are made from a matrix of small pixels, while other displays have larger elements. LCDs are used in a wide range of applications, including LCD televisions, computer monitors, Dashboard, instrument panels, flight instrument ...
