I notice that there is a new species of flat panel television called LED TV available in the electrical shops nowadays. Here are some of the fact finding.
Pioneered by Samsung, LED TV is in fact a LCD TV using Light-Emitting Diodes (LED) as its backlight, contrasting to the Cold-Cathode Fluorescent Lamps (CCFL) backlight of normal LCD TV. This innovation has made Samsung to receive a prestigious award from European Image and Sound Association (EISA) in 2006, for its premium display technology in terms of true colour representation with a 46% larger colour gamut and the industry's highest contrast ratio of 10,000:1 by then.
According to Samsung, their LED TV provides improvements in 3 distinct areas:
1. Breakthrough picture quality with higher contrast, sharper motion and enriched colour.
2. Ultra slim design at only 1.2" deep with lighter weight.
3. Environmental friendly with 40% electric power savings than normal LCD TVs, produce less heat, and also lead and mercury free.
It is also claimed that the LED light source can double the TV panel life compared to the CCFL panels.
Beside Samsung, other manufacturers such as Sharp, Sony, LG, Panasonic, etc. have also produced their own series of LED TV. Of course, you will expect the price of LED TV to be higher than LCD TV of the same size.
Meanwhile, the television technology keeps on progressing, and the next generation will be a true LED TV called Organic LED TV (OLED) using the Active-Matrix Organic Light-Emitting Diodes (AMOLED) technology, this time to be led by Sony.
The primary benefit of OLED displays over the LCDs is that OLEDs do not require a backlight to function, and consume even less power. This technology also enable the panel to be ultra-slim, weight even lighter, and more robust. Of course, better quality display can also be expected.
On the other hand, we can notice that the plasma TV gradually step down from the TV technology warfare, following the CRT TV, as there is not much technology breakthrough and also less R&D investment allocated by the major manufacturers.

This is a great Post!The Samsung LN55A950 LCD HDTV($4,999.99 list) is the company's second-generation LED-backlit LCD. Its 55-inch screen delivers impressive picture detail, and color accuracy. Using LED backlights scores big in terms of energy efficiency too, but you'll pay a premium over traditional LCD TVs,
Premetto che il commento seguente è puramente personale e si riferisce al territorio Italiano.
Non capisco come ditte serie tipo Samsung si impegnino sprecando soldi e risorse nella ricerca, di migliorare i pannelli LCD con retro illuminazione, quando la qualità delle immagini sui pannelli LCD sono di per se veramente brutte. Il pannello LCD e anche il pannello al PLASMA hanno un'immagine scadente, se viene paragonata ai vecchi CRT. Questa brutta immagine, diventa pessima se viene visualizzata su televisori con pannelli HD. Ormai in Italia è da parecchio tempo si parla e si vendono TV HD READY, e FULL HD, pero le emittenti che assicurano questo servizio sul nostro territorio si possono contare sulle dita di una sola mano, alcune sono satellitari e solo a pagamento. Pertanto non è assolutamente giustificato l'acquisto di un TV FULL HD. Spero che la tecnologia OLED abbia una qualità di immagine DECISAMENTE migliore, perché una cosa è certa che oggi come oggi piuttosto di cambiare il mio vecchio CRT con un LCD oppure PLASMA preferisco restare senza TV se non trovo un altro CRT. Posso assicurare che sono veramente molte le persone che la pensano come me.
Hi friend from Italy,
It is true that if the TV broadcast signal doesn't bring good quality picture, you will most probably get a poor quality picture even with the HD flat panel TV.
But the problem is not with the TV, and you can still get good quality picture with HD-DVD and a good DVD player.
Besides, the signal cable also plays a very important role in picture quality.
