After reading the countless of threads over here, I thought I better just give in my two cents before there are more confusions in the future.

What is advertised and marketed by Samsung as LED TVs are just LCD TVs which uses LEDs as their source of backlight.

The advantage this brings to you would be lower power consumption, more compact design (slimmer, borderless etc) as well as being lighter (so that the pencuri can run away with it easier).

Here are a few links to better understand the terminology of the technologies involved.

http://en.wikipedia.org/wiki/LED-backlit_LCD_television

http://www.ledtele.co.uk/whatisledtv.html

So all in all, there is no such thing as a true LED TV or what ever marketing terms. Essentially they are just LCD TV with a different backlight.

The different type of LED styles are as follows:
Edge Lit LED: These are LCD TV with White LEDs on the edge of the panel to light it up. Advantages = Thinner Panels

Back Lit LED: These are LCD TV with White LEDs behind the panel.

Local Dimming LED: These are LCD TV with LEDs that can be individually dimmed and brightened to adjust brightness at some part of a scene. Advantages = Blacker blacks

And the only one that I know off.. that is Local Dimming RGB LED, that I only know the Sony Bravia X450 to have. This is the same as Local Dimming LED, but instead uses Red Green and Blue LEDs to create a broader colour range.

Edit:
One more link for further reading.
http://www.ledtv.net.au/

Edit:
For those who are wondering what is a true LED Display.
http://en.wikipedia.org/wiki/LED_display

Edit:
A good comparison between "LED TV" and "LCD TV" as well as the technologies involved. Just take note under "Contrast and Black Levels" section of this article, they are talking about the RGD LED Backlights of the Sony's XBR range. Samsung 8500 series is similar to the Sony XBR in this department, except that Sony's XBR usus RGB LEDs while Samsung is still using only White LEDs.

Edit:
An external forum topic that also discusses about "LED TV" and to not get confused.

The real one, I think, is OLED (Organic light-emitting diode) which Sony got product for this but only 11" and selling price is USD2000++ tongue.gif

Mmmhmm, the real one that is to be watched in a living room that is. =)

There are LED Displays, but they're usually used as those large outdoor TVs and such.

Edit:
Since you mentioned OLED, better mention that it is a whole different technology all together as well. =).

If they're ignorant even after this post, then they deserve to get their money cheated from them =).

I guess mods could sticky this for the sake of new readers.

Actually, this thread is discussing the Technology behind it...
But what matters most is the Samsung Series 8 LED beats the hell out of most Plasma TV from what I see.
Dun get me wrong, I'm a Plasma fan and really hate LCD screen and the worst part, there is a dark outline for most objects that I piss off mostly.
Also, I really can't get over the black colors of a LCD screen...even for the higher end Sony sets.

But the Samsung Series 8 is something else. The LED backlight does wonders to the LCD visually.
I'm putting LED's on top of my list when shopping for a replacement for my Plasma.
For me, its that good.

you have to pit the series 8 with high end plasma, which it still loses...
if you take series 8 pijak S10 then susah la.. price also can buy 2 plasma already..

if you want LED backlight (to replace plasma), just make sure it's got local dimming and over 512 zones.. that should reduce the blooming problem caused by zoning the LEDs...

The reason I started this post is to bring aware to the public to not be drawn into the hype caused by this waves of marketed 'LED TVs'. I mean Malaysians are suckers for falling into hypes la honestly. Rotiboi la, the doughnut phase la.. I mean even cars also.. wait list here wait list there.. everyone Kiasu.. But back to the topic.

Correct me if I am wrong, but only does the Samsung 8500 series have local dimming LEDs and not the Samsung 8000.

Also, correct me if I am wrong, but the only two ranges I know with local dimming are the Samsung 8500 series as well as the Sony XBR x4500 series, in which Sony's LEDs are also RGB as opposed to Samsung's white.

So judging from this fact alone, the majority of the LED TVs that most Malaysians would be buying would just be an edge-lit LED, and following the links I have posted, edge-lit LED TVs do not bring about much improvements over other types of TV.

I can modify a 5 year old LCD to use LED as well and advertise it as LED TV. I am not wrong, following the 'defination' that is being used, but then the picture quality is going to be that of a 5 year old LCD.

So please be more aware when making claims such as "I'm putting LED's on top of my list" that LED in itself does not make a better TV and that there are TVs out there which does not use LED but still have fantastic picture quality.

Edit: Of course, essentially, it is the consumer's money and their choice to what they want to buy. So if you want to be drawn into the hype and just look at everything LED only, go ahead, but don't go and spread your false propoganda to others, that is all.

Edit: Here is a review on a 46" Samsung Series 8 as well as the 46" Sony Z5500 (Z550A for us here in Malaysia)

Take note that the Samsung's review is earlier than the Sony's as well. The Sony is also not using LED backlight, yet it is on par if not better in most areas when it comes to picture quality and speed (200Hz)

Yep. I was looking through the forums to get some information to help find a new TV for my dad, but more than half of the recommendations and suggestions here are all parroting false information.

But just the fact that the Sony 46Z5500 is as good as if not better than the Samsung UE46B8000 should hopefully cause future buyers of TVs to actually look carefully before falling for the LED TV marketing hype.

For me, from what I see with my own eyes, it does make a difference. But not for all LCD that uses LED. As you said, you can simply use a 5 year old LCD and fit LEDs to it.
I specifically mention Samsung Series 8.

Plasmas will always be Plasmas...and great at what they are doing, seeing a Panny both beside a Sony booth...one can only truly understand why the colors are so natural yet vibrate with depth.
Between the Samsung 8 and Panny S...could be my eyes is wrong, but for me the Samsung 8 is better...maybe I'm so use to watching Panny Plasma and Sony / Samsung LCD colors that I think LCD lit with LED is different and has the advantage.
If wanna compare price then its a different story.

Yeah, I know you did mention the Series 8, but you also did mention that it's either LED TVs or nothing and those kind of statements are misleading to others, that's all.

What I am just trying to get here is that LED is not what makes a good TV. It still depends on the other parts as well, and this is proven with the 46Z5500 (46Z550A here) with it's equal if not better quality to the Series 8 even though it does not use LED.

Plasmas technology is another example as well. I was always had this idea that Plasmas will always have better black level/contrasts when compared to LCDs... but after seeing the newer LCD TVs, a lot of Plasma models are losing in this department against the better LCD TVs.

Yeah, for me Sony top range are very good and the progress they made is impressive. Still not to Plasma standards but very - very close to it.
From BE2 to BE3 is a huge leap in performance.

See how the technology goes...

Yeah. Just sad that they don't have the Bravia XBR X4500 here though. That one is really a leap in performance.

I saw one right next with the Z5500 at JB-HiFi in Australia... seriously super nice contrast and all. Just that it costs 2x more.. and you thought the Z550A is expensive =P

They should be coming out with a replacement for that soon though, the X4500 is still using Bravia 2 Pro and 100Hz.
