From a while back in the thread:
Few points to make:
1) No LCD will ever have a perfect 180? viewing angle, simply because the LCD layer and filters would need to be infinitely thin to achieve this. Can't happen because you have to have _some_ liquid crystals behind each filter for the thing to work
2) Contrast is determined by the effectiveness of the crystal layer and the polarising filters, not the backlight - same for 'true blacks'.
3) The colour gamut, the whiteness of the whites etc is again affected by a lot more than just the backlight. A brighter, whiter back light will make some improvement but last time I looked into it, fluorescent cathodes were a lot 'whiter' than white LEDs. But LED tech moves at a pretty astounding pace.
LED backlights sound great to me, but I just worry about how even the backlighting will be given that they're basically just point sources of lights, rather than the convenient bars of cathodes.
My money is still on OLEDs in the long term though, since they do away with so much of what limits current LCD tech (LED backlights or not, you still need some sort of backlight, colour filters, polarisers...). There's a lot of money going into display tech and the lifetime bugs etc will be worked out of OLEDs pretty soon. Not that that didn't stop people buying plasma TVs...
I also think we'll see a raise in Apple's display prices but there will also be benifits to the newer displays:
Perfect 180º viewing angle (*)
Less power hungry (*)
Better contrast ratio
*"True" whites/blacks
Better color gamut
Better durability/lifetime
Lighter/thinner casings (*)
(*) A lot of these factor will benefit the laptops.
