Liquid crystal display.
The meaning of LCD=Liquid crystal display.

A low-power flat-panel display used in many laptop computers, calculators and digital watches, made up of a liquid crystal that is sandwiched between layers of glass or plastic and becomes opaque when electric current passes through it. The contrast between the opaque and transparent areas forms visible characters.

Optoelectronic device used in displays for watches, calculators, notebook computers, and other electronic devices. Current passed through specific portions of the liquid crystal solution causes the crystals to align, blocking the passage of light. Doing so in a controlled and organized manner produces visual images on the display screen. The advantage of LCDs is that they are much lighter and consume less power than other display technologies (e.g., cathode-ray tubes). These characteristics make them an ideal choice for flat-panel displays, as in portable laptop and notebook computers.

(Liquid Crystal Display) A screen display technology developed in 1963 at the David Sarnoff Research Center in Princeton, NJ. LCDs are quite extraordinary. Sandwiched between polarizing filters and glass panels, liquid crystals are rod-shaped molecules that flow like liquid and bend light like crystal. The orientation of the filters and panels determines how light passes through the crystals.

Because it takes such little power to move crystal molecules, LCD wristwatches began to flourish in the 1970s along with myriad other monochrome displays. By the 1990s, color LCDs helped the sales of laptops to boom, and in 2003, LCD computer monitors outsold CRTs for the first time, making LCD the predominant electronic display technology.
