LCD or Liquid crystal display, is a type of technology that has been used and around for several years. It is a popular technology with a number of advantages over other technologies and has been used in just about everything from televisions to personal calculators to computers.
The popularity of the LCD TV is shown by the increasing sales of the sets. In 2007, for the first time, LCD televisions surpassed sales of CRT-based televisions worldwide.
