I made some macro shots of E Ink Vizplex (4 gray levels) display. Maybe someone will find them interesting:

As you see the white background is not exactly white. Shows some dark speckles.

Photo camera used: Olympus E-520 with macro lens and additional macro converter. No flash, so it was very hard to keep still (and above photos are two of the 50 or so bad ones :) ).

And the black has some white speckles. This can also be appreciated with the naked eye, I guess it's due to "defects" in the screen, the proportion of which does not greatly impact the readability (manufacturing a defect-less screen, if possible, would probably be much more expensive).

Maybe defects. I'll have to check if they move - because they could be left by not ideal refresh of the screen (not all white/black moved to the top/bottom).

If you make a picture of an average pocket page, you'll see that those aren't perfect either. For me, the imperfections make it more realistic somehow... Must be a remnant of my pbook reading time :rolleyes:

I've looked at mine through a 60x mini-microscope (of this (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=150435327566) variety but lots of ebay sellers have them-- nice toy for the price) and you can just make out the individual cells of the display (not the pixels-- much smaller than that.) It looks much like the close-up appearance of styrofoam.
