Lcd Tvs and Plasma Tvs - Separating Fact From Fiction

Overall photo Quality: The plasmas and the newest models of the Tft-Lcd flat screens have the capacity to deliver high ability viewing gift crisp, clear and provocative pictures. The plasma though is the one recommended for home theater usage. The cells in the plasma Tvs are fixed in such a way as to forestall any light from leaking. This is an prominent highlight because it makes the blacks deeper, which help the plasma forward the light and dark pictures typical in movies and Tv shows in good quality.

To compare, Lcd technology involves the use of backlighting going straight through to the Lcd, this makes it difficult for achieving blacks that are true in nature, and the light leaks from in the middle of pixels.

This is not to tell you that these Lcd flat screens don't make good Tvs for you; the ones that are sold today haver better incompatibility and area able to produce deeper blacks than they use to, but plasmas still does this better.

Angle for Viewing: This is not genuinely as big of an issue, with the newer models of Lcds compared to the plasmas. But continue to read for more information...

Don't make the assumption that there is no issue when it comes to the angle of viewing when comparing Lcd to plasma screen. On average, especially with the cheap Lcd screens,  when viewing off axis the photo ability does fade more noticeably compared to plasma screens.

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 keeping 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 separate drawbacks.

Burn-in is not as prevalent with the newer plasma screens like it was in the older models, this is based on fairly regular viewing habits. With the Lcd screens today the image sticking is not as likely to happen when regular viewing habits are enacted.

Viewing Distance: Take the same size of both the plasma and Lcd and the Lcd has the smoothest photo of the two, as long as it is the same pixel count.

This requires that you be viewing within the distance that is recommended, which means for Hdtv that is duplicate 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 generally because it uses a much lower number of electricity. Approximately 30% less electricity used in fact with the Lcd opposed to what the plasma of a similar size uses.

Lifetime: The two technologies are about the same on this anymore. The plasma and Lcd Tvs both have been proven to have a half life of sixty thousand hours. If you just shape half this time of thirty thousand hours the Tvs would last about 14 years when watching them for about 6 hours a day. The people in  the Usa replace Tvs about every seven years!

The Lcd and plasma Tvs are based on a durable and reliable display technology today. So the lifetime seems to be more about the ability the Lcd or plasma is artificial at, more than the technology itself.
