Wellll.... since in OLED TECH the pixel is its own lightsource, that 1,000,000 to 1 contrast ratio is kinda fake (or marketing speek). Its basically the ratio of a turned off lightsource to its top brightness.
WHAT I would like to see is the ratio for the very darkest black that it can display BEFORE turning off the pixel, to me that would be the true ratio.
Why? it can turn off the pixel while working, that's the whole advantage, and the a reason why it has good blacklevels, so the ratio is true. That's also a reason why they try to use LED backlighting in LCD's that can selectively be turned off in areas. And why do you have issues with a new and better technology coming around? The tricky thing with OLED is still the lifetime of the display. And seemingly the power it needs?
I have no problems with new technology (I am a POST supervisor at pretty big facility, I LOVE new TECH ;-) )
The issue is that then the actual ratio theoretically speaking is 1 to infinite, since a turned off pixel is essentially ZERO. I would rather be interested in knowing whats the best black that it can display without turning off the pixel. This in turn will let us know the accuracy of those almost black colors.
IF it goes from .1 (a number for comparison purposes only, from 1(white) thru 0(black) lets suggest) to 0.0 by turning OFF the pixel, then that means there is no control over that range of color. in case of a 10 bit display (2^10=1024 luminance steps) you would be loosing control or calibration capabilities over the lower 100 luma levels (I dont know the threshold where it would stops emiting light, when/if we know then we can figure this out better.)
Even if it went from .01 directly to 0.0 you would still loose 10 steps. Visually this could mean that a slow fade from black you could feel a visual "pop" when the image starts to fade in.
peace.

OLED do have the best contrast ratio. Stop acting like you know what you're talking about. Every site that has seen this in person says it looks like a photograph. OLED has the advantage of true blacks and whites, so if something is letterheaded it doesn't waste power and doesn't take away from the main screen by lighting the black pixels.
You have to allow for light that spills into the "off", "black" pixels from neighbouring pixels that aren't off, and maybe also from ambient light (reflections?). I'm not sure to what extent they allow for these in their measurement methodology when they come up with those "1:million" numbers, but in practice these are the affects that will determine how good it looks.
since OLED is considered emmissive rather than transmissive, techically no light should leak from one pixel to a neighbouring pixel in an OLED display.
We have noted some uniformity issues in a current large format LED model recently released by one of our competitors, however from our findings this is due primarily to the controller versus any sort of actual pixel-to-pixel transmission.
I think we know from normal LED that it doesn't make such sudden jumps from off to low-on, and to max brightness. And if you are so close to technology how come you have never seen a iRiver click or some such device with an OLED display? get out to some store and go check for us :)
The phone has 256MB of RAM and a 1GHz processor, which do the job reasonably well, though the Anna interface will likely leave something to be desired for many smartphone users.
