People will look at price first. Your average consumer will not even bother with a true LED HDTV as long as the price is a problem for them. Many willingly settle for good old backlit LCD HDTV.

whats d fuss? LED tv is jus a term for average consumer to differentiate tht those LED-backlit LCDs are abit different frm d normal LCD..

average uncle dun realy giv a damm whether its LED Tv or LED-backlit LCD, as long they notice d difference in brightness, contrast, color....

even laptop lcds nowadays r using dis terms..

The fuss is that a lot of average consumers don't see LED TV as just LCDs with LED backlights, but something more. Average uncles also don't know and see LED TV and just buys it because it's 'new'. And a lot of stores don't set up the TVs properly so you can't judge from what you see in stores as well. That's pretty much it.. lol..

Isn't there newer cheaper LED TVs out there now? Sorry arr.. haven't really looked at TV prices.. Also considering that there's already Series 8, wouldn't the Series 6/7 be cheaper too?

LoL... And this is the advertisment at the top of this page =P

Samsung LED TV advertisment

I myself was confused as well. I first heard of these LED TVs when I saw the Sony XBR in Australia. The colour and contrast level was really good compared to the other models (Z5500 included) and that's where I started looking and coming across the use of LED TVs.

When I saw Samsung's LED TV logo (as shown above), I initially thought they were using the same technology/method as Sony, only to find out that it's only just LED Backlights on the edge, not even behind (until the Series 8.5).

Just the fact that yourself and myself were confused at first shows that there are many out there who would be as well, better to just put the facts down for people to see.

My 2 cents.

LED backlit LCDs are have an edge over CCFL backlit in 2 ways. There are better overall black levels and lower power consumption.

However, there are problems with uniformity issues due to edge lit designs. As the screen sizes become bigger, the uniformity is worse. This will be more apparent when u get back home and watch under dimmer light conditions. Worst still if u watch in dark conditions when there are dark scenes. The centre of the screen will not be as dark as the edges. Also because of this, the colour rendition is also not as accurate. Coupled with some sets having non defeatable (in user menu) auto dimming, these are the known issues with edge LED lit LCDs.

Also in the future, there will be no way to implement local dimming edge LED lit sets. The true LED backlit performers are the ones with local dimming capabilities. As ar188 said, the more zones the better to reduce blooming effect. Another concern of mine is the use of white LEDs instead of RGB array LEDs for colour accuracy.

There terminology is misleading but its works wonders to get people excited. However, the layman could care less. They always want the newest, highest numbers (eg, 240Hz) and the cheapest when looking for products.

One high point to Samsung is the availbility of a full 3D CMS which is the best implementation on a consumer set that I have seen. I am unsure if the Sony Z series offers a CMS.

That said the Sony normally has a more solid implementation of the motion interpolation engine in the LCD camp.

lol i just bought the samsung led tv series 7, in my opinion, people who think about buying these led tvs do have the purchasing power, therefore they just want to get it cos its the newest and dont really care if there isnt much difference to the regular lcd tvs. in fact, 40% less power is enough to seal the deal. my rm0.02

You must remember where you get the 40% figures from though.

My Sony 46Z5500 (Z550A) uses 185Ws in operation and from Samsung's site, the UA46B7100 uses 170W.

But that aside, power saving is useful if you use your telly a lot. I know someone who has theirs switched on whenever they're awake for their kids and all, lol...

If I not mistaken, power comsumption is very according to content of the tv (i.e. which colour the TV display will affect the power comsumption of you TV). So, 40% saving may not always true.

for LCD is pretty constant.. cos the backlights are always on.. even for LED (non local dimming types)

for plasma, that's a different story, power fluctuates depending on the content of the TV as you mention, not every movie scene is a full White screen or White noise (max power condition)

yeah read about that... cos additive color RGB (using the green + red portion) can't really make reallife yellow properly.. so need to add pure yellow component..

this is a good thread. i stopped counting how many people told me they want to get that new LED tv quick because it's "BETTER".

Having said that, I can't afford any of the models being discussed by forumers here, but this is definitely useful info.

well, it's better than CCFL but not exactly a new technology as it's still LCD at the end of the day, only the backlight portion has changed..
