pluggedPlasma Technology has been with us since its inception in the mid 1960�s and it is indeed LCD (Liquid Crystal Display) Technology that is actually the younger and newer of the two types of technology available with Plasma being with us since the mid 60�s.
If we look at the basics of the technology behind it we find that in its simplistic form it is the heating up of tiny cells with inert gasses trapped between two panels of glass that comprise a Plasma Display Screen.

Depending upon the electrical signal generated and the resulting heat from the reaction with the Phosphors the colour in the cells can vary and this tends to lead to another assumption that in the early days Plasma screens were very much power hungry.

Now I know this is a gross over signification of what actually a Plasma Display actually does and this will no doubt cause many a technical geek to start foaming at the mouth but in a nutshell that's what plasma displays do.

Developed in 1964 at the University of Illinois at Urbana-Champagne the actual technology of Plasma displays has been around for some time and indeed is possibly the oldest of the so called �second generation� of technologies in use in television today.

Screen sizes for plasma displays vary and have increased somewhat since the humble 21 inch displays launched in 1992 and now you can get plasma displays in a variety of sizes and you can now find commercial displays available in excess of 103 inches in screen size.

LCD TV�s have certainly closed the technological gap that had hitherto existed between the two technologies and all of the previously strong areas that Plasma had dominated over the years are no longer really applicable at the present stage in time.

In these eco friendly times you will find that one of the main selling points with LCD screens nowadays lies with the fact that Plasma tend to be very power hungry (and as such warm) and by and large heavier so very much of an environmental disaster zone as far as TV�s are concerned.

Since 2006, which according to analysts was very much a watershed year in that it was the year that LCD TV�s really started to take market share from the Plasma manufacturers, LCD TV�s have started to share the large screen market with Plasmas. One of the other areas of consolidation within the Industry has seen the Plasma manufacturing base very much consolidate with now over 50 brands being manufactured by only 5 companies � this of course has led to economies of scale hitherto imagined where the technology of more and more screens can be shared and further help cut the overall cost base.

{Historically the superior brightness of Plasma Technology made it a favourite amongst TV designers for the faith rendition it gave the picture quality however this is now starting to be matched with the latest and better quality LCD TV�s appearing into the marketplace.|Over the years it has been felt that some of the technological aspects of Plasma technology leant it self more to the higher end of screen performances such as greater brightness control, screen resolution etc) however this is now changing. Whereas LCD was very much seen as a cross between the poorer relation and junior technology of the two, now things have changed and LCD is seen as being very much the technology of the future.
