What is an LCD in a camera and how does it work?
An LCD, or Liquid Crystal Display, is a type of display screen used in cameras to preview and review images. It works by using a layer of liquid crystals to block or allow light to pass through a matrix of pixels, creating images on the screen. The LCD screen is typically located on the back of the camera and is used to display a live preview of the scene being photographed, as well as to review images that have already been taken.
The LCD screen is usually connected to the camera’s image sensor and processor, which send the image data to the screen for display. The screen is also often equipped with features such as brightness and contrast adjustment, as well as the ability to display histograms and other image data. Some cameras also have touch-sensitive LCD screens, which allow users to interact with the camera’s menus and settings by tapping on the screen.
