Plural of LCD, standing for Liquid Crystal Display - a type of flat panel display technology that uses liquid crystals to control light passage. Common in televisions, computer monitors, and mobile devices.
Acronym formed in the 1960s when the technology was developed. 'Liquid crystal' was coined in 1888 by Austrian botanist Friedrich Reinitzer who discovered substances that had properties of both liquids and crystals.
LCDs revolutionized display technology by using tiny molecular switches instead of glowing phosphors, making screens thinner, more energy-efficient, and capable of true flat-panel design. The liquid crystals literally twist and untwist to block or allow light passage, creating images through millions of microscopic shutters working in perfect coordination.
