LCD Definition/Meaning:
Abbreviation for liquid-crystal display. A device incorporated into many digital
watches, calculators, some small computers, instruments, etc., in order to
display numerical and alphabetical characters. The display comprises groups of
segments from which individual characters can be formed. Each segment consists
of a normally transparent anisotropic liquid sandwiched between two transparent
electrodes.
Application of an electric field across the electrodes causes the
reflectivity of the liquid to change and the segment becomes opaque. Individual
segments can therefore be selectively darkened to form a character. The digits
and some letters are typically produced from groups of seven segments. Unlike LED displays, LCDs do not generate their own light and thus require external
illumination; they do however have a lower current drain than other forms of
display.
