Overall Picture Quality: The present TFT-LCD flat screens and the plasma screens both can produce clear, bright, crisp images for a great picture quality. But for use in home theaters the plasma screens show better performance than the LCDs do. The plasma screen contains gas cells that are arranged in such a way that the light does no leak out between the cells. This enables the plasma screens therefore can display more intense blacks, making these screens very suited to those scenes in movies and TV scenes in which light and dark lit scenes are shown together. In contrast the basis of the technology covering LCD, is the use of a backlight to illuminate through the LCD layer, and this creates a problem with the LCD being able to come up with the real deep blacks that plasmas do, because of the light that seeps out to other pixels. Don't think though that LCDs don't still make good TVs, now the LCDs are made with panels that are high contrast that can display the better deeper black, but experts still say that the plasmas still have the advantage slightly. Angle for Viewing: This is not really as big of an issue, with the newer models of LCDs compared to the plasmas. But continue to read for more information... The viewing angle is still a problem at times though between LCDs and plasmas. When you have a cheap LCD rather than a more quality one, you can still see the picture deteriorate when viewing takes place from the side more than when you do the same type viewing with plasmas. The Burn-in and the Image Retention: In these areas the LCDs take the lead. They not only don't have the inclination to get burn-in but with the image sticking or image retention it can be reversed in these. Realize though that while the plasmas can suffer burn-in and image sticking can happen in LCDs, and that both conditions can then cause image retention, that these are two different drawbacks. Today the plasma's burn-in is not as much of an issue as it was in past years, and more so with the people who watch TV at a normal rate. With LCDs the image sticking situation does not happen like it used to under of course normal viewing. Recommended Distance for Viewing: The LCD flat screen has been found to deliver a picture, that is much smoother to watch than a plasma screen does that is of the same size and pixel count. This requires that you be viewing within the distance that is recommended, which means for HDTV that is double what the width of the screen is, and if this winds up being shy of 9 feet, than you will get better viewing with the LCD for your TV. Usage of Power: In the power category the LCD wins by far mainly because it uses a much lower amount of electricity. Approximately 30% less electricity used in fact with the LCD opposed to what the plasma of a similar size uses. Lifetime: Both the LCD and the plasma come out equal on this. They are both rated with having 60,000 hours as far as half life. Even if the amount was only 30,000 hours, this equals over 14 years for using it if the viewing time is an average of 6 hours daily. In the USA the average person buys a new TV at the rate of one every 7 years! One will find that LCD and plasma TVs are both manufactured through very durable and reliable types of technologies. The quality of the make is more important for the lifetime of the TV than the different kinds of technologies.
