What is the functionality of LCD?

LCD, or Liquid Crystal Display, functions by using liquid crystals that modulate light to produce images. When an electric current passes through the liquid crystals, they align in such a way that they either block or allow light to pass through, creating various colors and images. This technology is commonly used in screens for televisions, Computer Monitors, and mobile devices due to its thin profile, energy efficiency, and ability to produce sharp images. LCDs typically require a backlight to illuminate the display, as the liquid crystals do not emit light on their own.
