LCD is a common flat panel monitor technology. This type of screen is used often in televisions and computer monitors.

What Does LCD Stand For?

LCD stands for Liquid Crystal Display. This type of screen gets its name from the liquid crystals the screens use to block out light from the backlight and produce images.

How Does an LCD Screen Work?

LCD screens have two glass panels with cold cathode fluorescent lamp backlights behind them, and a layer of liquid crystals sandwiched between the glass panels. The lamps output light while an electrical charge is put through the liquid crystals. This allows different amounts of light to pass through to the second layer, which contains filters which help to create the image.
