LCD
LCD stands for Liquid Crystal Display. It is a type of flat-panel display technology commonly used in screens for computers, televisions, smartphones, and other devices. LCDs utilize liquid crystals that modulate light to produce images. The display consists of several layers, including a backlight, polarizers, and the liquid crystal layer, which changes its alignment when an electric current passes through it, allowing varying amounts of light to pass or be blocked. This technology is known for its thin profile, energy efficiency, and ability to produce sharp images with good color reproduction. LCDs are widely used due to their versatility and affordability compared to other display technologies like CRT (Cathode Ray Tube) or OLED (Organic Light Emitting Diode).
