That may be due to it's being a different approach to the display (I don't know that it is
different, I'm just wondering if it might
If it's set up to only address the segment section as a block instead as individual pixels the way the e-readers we've seen are, then the black flash likely wouldn't be needed to get the same crispness. It would effectively be treating each segment as a separate display area, and therefore effectively changing the entire display area as a unit.
Again, I don't know that this is what's going on, I'm just theorizing based mostly on my experience with the differences between a 7 segment LED display module
(where each segment is controlled as a single, discrete unit), and one of those programmable LED matrix signs
(where letter 'segments' are made up of multiple individual LEDs controlled as a group).
In any case, thanks for the overview -- it's good to get some real-world feedback on what these phones are like.
