INFO: What is LCD?

LCD or Liquid Crystal Display is a technology that uses liquid crystals to alter the color of light as it is passed through them. The liquid crystals do not produce light by themselves, so another light source, typically a cathode or fluorescent backlight, is used to provide the light. There are several layers to a standard LCD screen. These layers polarize, filter, and either block or pass light to show an image.
LCD displays are more energy efficient, lighter, and in general provide a superior image to their CRT (Cathode Ray Tube) counterparts. These characteristics have made them popular for use in computer monitors, televisions, and gaming devices.

Here are a few tips for the care of your LCD screen:

  • The surface of the LCD is not as hard as glass and can be scratched if not cleaned properly. There are a number of products available that are designed to clean LCD panels. The key is to use a soft cloth; paper towels, or other abrasive cloths should not be used since they can easily scratch the film of the LCD panel. DO NOT use standard window cleaner or other ammonia-based cleaners as they can cause hazing of the LCD panel.
  • If you need to move the monitor or television avoid rough handling or jarring. Also avoid contact with the LCD screen itself.
  • Keep the vents clear to allow for ample cooling.
  • Avoid extreme temperatures. Below freezing temperatures can alter the liquid crystals and in some cases could freeze them causing damage to the matrix. Excessively high temperatures can cause failure of sensitive electronics due to overheating.
