Liquid crystal display (LCD) is a technology that has revolutionized the way we interact with electronic devices. It is a type of flat-panel display that uses liquid crystals to produce images and videos. Unlike traditional cathode ray tube (CRT) displays, LCDs are lightweight and consume less power, making them a popular choice for portable devices such as laptops, tablets, and smartphones. The history of LCD dates back to the early 20th century when scientists first discovered the unique properties of liquid crystals. Since then, LCD technology has undergone significant advancements and is now widely used in various applications, from consumer electronics to medical equipment and automotive displays.
