Not hugely different but slightly better quality but cheap as hell.

Any screen I buy from now on, whether its a computer screen or a TV will have to have LED backlighting - preferably with local dimming.

The difference it makes is stunning. Contrast ratios from 50,000 > 500,000:1.

cant argue with that, I think they probably will

That and the glass gloss finish for me makes a screen so much more rich

70"
1080p
120hz
Local Area Dimming LED Backlight
HDMI 1.3
500,000:1 dynamic contrast

Simply mental.

Theyre bringing out smaller version of it (40, 46, 52, 57) although the contrast will be lower, 100,000:1 or so. Apparently with the new tech, the bigger the screen gets the more more LEDs they can map to a screen so higher the contrast or something like that.

Samsung are also working on 24 & 30" LED backlit monitors... and I believe Dell use Samsungs panels.

Dell do, actually just reading this is the thing the led backit bit is waiting on wether or not samsung have them ready in time.

dell PC screens are in a sense samsung pc lcds with nice dell tech and design with them.

I think I will defiantly be a dell lcd for computer and Samsung lcd tv person for a long time to come becuase both for cost and performance is hard to beat at the moment.

drooooooool over that screen though

I hate backlight!!!

It is an invention to fool the eyes into thinking the blacks on LCD are really black by flooding the eyes with more light to give more contrast. Simple and crude.

Ive gone back to my 19" 0.27 pitch CRT and the picture is so much clearer with better colours.

As for the TVs, let me just point you to this link!

LCD, good but not a candle to true CRT greatness.

Would not argue if it was a few years, ago, seems your lost in the past a bit and not aware of a lot of stuff.
LCD backlight is not old school crap backlight, lol and with all the other tech in an lcd now and still decent cost, That crt or and lcd that will be the same spec and performance but no miles of back behind it, think ill stay with lcd thanks :)

Thats the whole point of local dimming LED backlights intsead of using conventional CCFLs.

If a part of the picture is black then the screen simply turns off the corresponding LEDs. This means it actually is black, unlike the LCDs were used to where the CCFL stays on through out the screen so black appear to be greys.

He is just a little behind on his tech bless :)

Do these screens map an LED to each pixel?  I cant see it being the case personally (although Ill gladly stand corrected) - in which case surely youll still be in the same boat with small areas/the edges of blacks?

No they dont map a LED for each pixel, thats probably impossible. I see what you mean, although the bigger a screen is the bigger a pixel is, so it begins to make less of a difference. I think thats why 70 inch screen can enjoy 500,000:1 dynamic contrast while a 40 inch screen will only have 100,000:1 dynamic contrast using the same system.

Im fairly sure they do when you run them in Native Mode.  That would be why most LCDs will display over the size they can, but the screen becomes slidey.

Quite like the look of that CRT actually.

a 1280x1024 screen has that number of pixels, hence the term "Native mode".  Ive also found that some of the ATi mobility gear will allow you to set the screen res REALLY high, but then the screen becomes dynamic and you use the mouse to scroll around it.

Yes, but all that has nothing to do with LED backlighting.  TFT pixels arent LEDs.
