LCD

LCD, or Liquid Crystal Display, is a type of screen used in devices like TVs, monitors, and smartphones. It works by sandwiching a layer of liquid crystals between two layers of glass or plastic. When electrical currents pass through, these crystals change their alignment, controlling how light passes through each tiny pixel on the screen. A backlight shines from behind the display, making the images visible. This technology allows for thin, lightweight screens with sharp images and good color accuracy, making it energy-efficient and popular in many modern electronic devices.
