Plasma Displays and the comparison with LCD TV?s, which one is the future?

People are quite often of the opinion that Plasma Displays are very much the latest in a series of technologies in use within the Flat Screen TV industry of today whereas in fact it is one of the oldest of the technologies available

To bring it down to its most simplistic form plasma display works effectively by housing many thousands of tiny cells located between two panels of glass which are held in a mixture of inert gasses usually Neon or Xenon.

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 this is admittedly a gross over simplification of how Plasma Technology works and may cause the palpitations and increased heart rate if possibly every ?techno geek? known to man but in its very essence this is what it does.

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.

Nowadays you’ll find that the low electrical power consumption of LCD TV?s the lower actual weight and falling prices have actually made LCD TV?s much more competitive with regards to Plasma Screens.

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. 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.

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.

The Hitachi 26LD200 LCD Flat Screen TV, For The Price It Will Take Something Special To Beat This.

Viewing television nowadays is certainly different from the humble experience it was in the early years under John Logie Baird to the vast array of images now viewable on the amazing Liquid Crystal Display /Flat Screen TV sets of today. The many benefits that most people derive from TV have made it indispensable in their lives.

Highly complicated yet when reduced to its basics quite frighteningly simple in execution the process of the television broadcast is one that very few people actually understand entirely or do they? The term television may refer at one point specifically to a television set yet also at the same time be used as a term to refer to the medium of television broadcasting itself.

Understandably if you were to ask the average man in the street his biggest issue with television today most would reply that the one problem they have is an increasing dependency on technological terms and an increasing ignorance of what these terms actually mean.

Rather than continue with a basic history of the industry, it might be best to stop and take a look at the latest developments within the industry mainly that of digital television, what digital television actually means, its formats, bandwidth and the technical terminology and jargon used today.

So how would you describe Digital TV? Digital television is a telecommunications system for broadcasting and receiving moving pictures and sound by means of digital signals in contrast to the more established analogue systems which is effectively the transmission of signals used by analogue (traditional) TV.

How does Digital TV differ from an analogue one? Using one of the newer LCD TV?s available will help us actually go through what all of this terminology actually means.

The LCD TV that we shall use for our illustrative purposes here is the Hitachi 26LD200 LCD Flat Screen TV.

The following items of information have to be understood before you can make a proper valued judgement regarding your new Digital TV?

The Screen resolution of the TV is possibly the most obvious place to start. Here we refer to the exact number of pixels that can be displayed in each dimension.

Whether the TV is Hi-Definition Ready would be the next thing to look at. By Hi Definition Ready we mean that is the TV is ready and suitable to take advantage of the latest Hi Definition TV pictures that more and more programmes are being broadcast in.

The next item that we would need to look at is what types of connectors are used between the peripherals used alongside the main Digital TV?

We are referring here to the exact nature and number of the Scarts Sockets and Plugs in use. Here the definition of SCART refers to ?Syndicat francais des Constructeurs d?Appareils Radio et Television (SCART).

Lastly on the technical side we would need to look at what types and what numbers of High-Definition Multimedia Interfaces (HDMI) are being used. The High Definition Multimedia Interface (HDMI) is a licensable audio/video connector interface for transmitting uncompressed digital streams between digital audio/video sources such as set-top box, HD DVD Player etc.

The 32LD9700 is a 32in LCD TV and these TV’s at present can be found in the region of 1000 pounds sterling or 2000 US dollars. The resolution of the screen is 1366 X 768 and with regards to being HD Ready the answer is yes. The Hitachi has 3 (2 RGB) scarts and the type and number of Multimedia interfaces the 32LD9700 uses is HDMI and 2. The type of Tuner for this TV is Analogue and Digital and the Hitachi is available from a wide variety of outlets.

So how would we rate the Hitachi 32LD9700?

First up, we would look at the picture quality and our score here would be 10, and closely tied in to the picture quality is the sound quality and our score for this would be 10. Another useful aspect to review is the availability and number of relevant connections and our score here would be 8. If we take a look at the overall “featureability” our score would be 10 and for ease of use and overall value for money we would give it, 10 and 10 respectively.

Finally our overall opinion would be WOW what can you say but that this is one of those TV’s that excel in almost every thing it is supposed to do. Described as a “Superb All-rounder”, there is not much that this TV does not achieve. If you can get your hands on one of these then go for it.

With regards to the prices in this article we have tried in all cases to take an average across the industry from a number of well known web sites and so we ask you to bear this in mind and treat these prices as advisory only rather than absolutes.
