Why does OLED always feel like its still two years away? <sigh>
@TV wrong mate - just sooo wrong!

@TV - that made me chortle, the irony of your moniker coupled with your untapped knowledge on Organic LED screens:)

Do you know the fun part, your trust in wiki - OLED 'is' the new backlight, instead of the 'usual' strips of light behind an LCD panel OLED are bulbs situated around the edge of the screen thus illuminating the panel, and I QUOTE the rest of the technology is the same as LCD. Sorry, i just build em saddo's.

@TV - I'm afraid you're confusing LED backlit screens with OLED screens. The biggest difference is that the former is transmissive (i.e. the LEDs generate the 'usually' constant light source, either from the back or the side, which is then selectively passed through the colour filters of an LCD to make the picture). The latter, however, is emissive (the coloured light is generated directly from the OLED layers with each sub-pixel individually lit and controlled by its own light source).
The two technologies are only similar in that both display types will (unless it's a passive OLED display) use an active matrix TFT layer to route and control the power to each sub-pixel - that's why some OLED displays are also called 'AM-OLED' displays.
Some of the advantages of an OLED display are: Excellent viewing angles because the light is emissive by nature. Good contrast and colour fidelity because the light output of each pixel can be controlled. Low power consumption. And of course a thin design because there is no need for a separate light source at the rear or the side.
OLED displays are, by design, quite simple too, which has enabled some manufacturers to construct fancy evenly-lit 'flexible' OLED displays - its not exactly practical to make a flexible display with a light source that's fixed in-situ like those found in conventional LCDs and LED backlit LCDs.

@TV, no, you are incorrect. OLED do not even have a backlight. Read here for more information: http://en.wikipedia.org/wiki/Organic_light-emitting_diode
