Sony has unveiled color e-paper. One thing I had hoped with the iPad was that the screen would be some kind of new, advanced color e-paper, since rumors were they were going to market it as a reader.
If this works well enough, I’m pondering whether or not it’ll work well enough for digital picture frames. Judging from the display appearing in the article, it would be. I like digital picture frames, but I hate the backlighting. This makes them difficult in a bedroom, living room, or any place where you might be distracted by the soft glow of fluorescent backlighting.
At the least color e-paper will mean readers like the Kindle can host color content, for things such as magazines. I doubt Apple would want to go that route with the iPad, now that it’s out, and it’s pretty clearly a more general purpose tablet computing device. This should keep the Kindle and Nook competitive with content, like magazines, that demand color.
