They HOWEVER have something that they call as 100hz Double Scan (not that I even know what it does).

Anyways, this is what they say:

Or whatever it says

Here is an example of rearraging subfield strengths to reduce flicker in Plasma displays.

Over thinking, over analyzing separates the body from the mind

So what's up with this Panasonic drive method? 3D drive seems to have time for 14 subfields+reset and drive goes from bright to dark. This is possible done to prevent crosstalk between images. Yes I counted only 5 subfields, but this can't be right.

I counted 12 subfields + reset for 2D image, but there seems to be time for ~30 subfields + reset.
