Interesting, but don't CCFLs also "flicker" just at a much higher rate?

Yes; I can see the flickering on my CCFL-based ThinkPad, but it's thankfully not annoying.

YEOW. OUCH.

I...... I am very glad I'm using a CCFL laptop. This is like going back to evil 60Hz CRT flicker!!

I've just accepted I might need to rip out the LED driver board in a future laptop and replace it with my own design. Hopefully not, but if that has to happen then okay.

Thanks for the reference to the comparison, that was also very interesting to go through (and bookmark).
