A Background To Plasma Flat Screen Tvæs And Displays. 15

The Future of Plasma Flat Screen Technology and LCD TV’s

People tend to confuse terminology with regards to television let’s take for example the “plasma television”. Well technically there is no such thing as a plasma television what you are actually referring to is the display and actually a plasma display panel (PDP) is only one of several types of flat panel displays now commonly used for large TV sets or displays.

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.

Again to be simplistic about it effectively what happens is that the gas in the cells is electronically turned into plasma which then triggers off a reaction with the gas and causes phosphors to emit light therefore depending on the temperature of the gasses and the electrical current depends which colours the phosphors turn into.

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.

With regards to the actual technology itself Plasma technology is probably one of the older forms of technology used for televisions and flat screen TVs in particular since it’s been around since 1964 when it was first “conceived” for want of a better description at the University of Illinois at Urbana-Champagne.

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.

From 2006 onwards industry analysts noted that effectively LCD TV’s were overtaking plasma displays particularly in the large 40inch plus market where basically plasma previously enjoyed a massive dominance since the inception of technology. Another interesting industry trend is that effectively manufacture of plasma displays has consolidated from about 50 odd plus brands available but these are only from five manufactures so the upshot of that is that plasma technology is fighting back in terms of economy of scale because as you can imagine with 50 brands from five manufactures there are certain economies of scale with regards to the reduced duplication of internal technology.

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. For quite sometime there was a general misconception within the marketplace that LCD technology only suited small screens and that Plasma was effectively the main provider of all large screens.
