LCD, or Liquid Crystal Display, televisions are one of the new technologies that have largely replaced the CRT, or Cathode Ray Tube, televisions in the Home Theater market. The LCD is somewhat familiar to most consumers familiar with computing as it has been widely used in monitors, and the trait that has made them popular in computer monitors is the major advantage in the television also. They can be extremely thin while having larger screen sizes. The elimination of the cathode tube has allowed this, and LCD TVs can be mounted in just about any place a picture could be hung.
Other pros of the LCD are their low power consumption, and the ability to use non-reflective screens which greatly enhances the picture quality in lighted rooms by eliminating glare from the environment. The LCD is also very rugged and less susceptible to damage in shipping and installation than most of its competition. The technology used to produce the light image retains brightness longer as well, and can even be recharged to a degree.
There are some cons. Because the light is reflected to the screen through tunnels directly behind the screen the image is perfect when viewed head on, but suffers a bit from angles. Also, the response time lags a bit, and this produces some blur in fast action images. The maximum screen size lags behind other flat panel technologies also. LCD TVs have a little higher cost to screen size ratio than its major competition.
LCD technology is advancing rapidly, and most of the negatives are being addressed and improved with each new entry into the market.
