What is difference between plasma tv and HDTV?

To my knowledge but I could be wrong. HDTV is High Definition tv. Just better quality of picture in comparision to normal definition or standard definition.

I hope that some one else can confirm what I said is right.

Most plasma televisions are a sub-category of High definition televisions such as LCD, or CRT. A TV has to be able to support 720 or 1080 (i)nterlaced or (p)rogressive horizonal lines of resolution to be considered an hdtv.

Plasma HDTVs are prefered over lcd models for their ability to display darker colors.

High-definition and flat panel TV’s are taking out old fashioned tube TV’s and their poor picture quality at an amazing rate. More and more people are trading in their old, bulky TV’s for state of the art LCD and Plasma screens. Besides their sleek and thin look, LCD and a plasma tv have lots of additional features.

LCD stands for liquid crystal display. These types of displays have been around for a .while and are commonly used with computers. One reason for their big popularity is the ability to produces a better picture than CRT monitors but also being much thinner

Plasma technology hasn’t been as widely used as LCD in previous years but has become very popular in large HDTV’s. Although they have historically been more expensive than LCD TV’s, they are becoming more comparable in price.
