Plastic Logic Shows Off a Color ePaper Screen 50
Nate the greatest writes "I'm sure you've heard about the color E-ink screen which was rumored to be used on the next Kindle. As of today, E-ink no longer has that market niche to themselves. Plastic Logic held a press conference in Russia this morning where they unveiled a new color screen that uses their plastic-based screen tech. The resolution is low (75ppi), but if the video is any sign, then this might be a better screen than the 9.7" Triton color E-ink screen used on the Jetbook Color. And that's not all Plastic Logic showed off this morning; they also developed a frontlight for their screen, and they can play video at 12 frames per second. But best of all, they cut one of their screens in half just to show that it could still work."

If you can produce something at 75 ppi that's intended to be held at standard reading distance, then you're just fine - you're relatively close to computer monitor spacing anyways and you're really not that far off from the standard printing dimensions of a paperback book.
If you're expecting someone to hold it up to their eyeballs for cheap laser surgery [wikipedia.org] (or hell, a pattern of eyeball abuse that'll cause them to need laser surgery eventually), then maybe you want more pixels. Not that it'll really help you,

1/75 of an inch held at 12 inches from the face takes up 3.1 arc minutes of viewing area. The human eye's resolution is about 16 arcseconds - over an order of magnitude better. Most people with good vision would almost certainly notice a level of blockiness and poor quality.
Apple's retina display is the first one I've seen that I don't notice individual pixels on unless I'm paying attention for them.

Ever held a paperback book that close to your face to read it? Notice the type looking a little bit "blocky"? Notice how you can see the flaws in the printing process?
No different. 75 ppi is just fine for an e-reader. And no respectable optometrist EVER recommends holding the book at that distance. Hold it at standard reading distance instead (say, 24 inches or higher) and run that calculation.

I measured 24 inches from my eyes, and in order to do so, I had to old the measuring tape up with my fingertips, with my arms fully extended. No optometrist in his right mind would recommend such a large reading distance. Maybe for TV viewing, but not reading.
Typical reading distance is 14-16 inches. So although 12 inches might

No it isn't. :) It's in the same ballpark than a 15" 1024x768, pixel size being around 0.3 mm. You would have to double the pixel density for it to be good for an e-reader.

order of magnitude = power of ten.
3.1 arc-minutes = 186 arc-seconds.
186 arc-seconds/16 arc-seconds = 11.625, which is more than ten.
Hence more than an order of magnitude better.

According to Wikipedia, the current eInk Kindles are all about 68 [wikipedia.org] ppi. So this screen would be as good (if not better) than the current Kindles in that department.
Unfortunately, this screen looks like it lacks color saturation, which seems to be a common trait among all color eInk displays. It's a big improvement over previous displays, but I still wouldn't put it in a product yet. People would immediately put it next to LCD displays, and compared to the display on a $60 "might as well sell it at the drugs

If you follow your own link, you will see that according to Wikipedia, current eInk Kindles are about 67 ppcm, which is around 169 ppi. So this screen isn't half as good as the current Kindles in that department.

Yeah, but flexibility is different than resistance to cracks, impact and shearing. Two different types of force.
