You might recall that one of the major events last week was the simultaneous announcement of the graphite Kindle DX and E-ink's new screen tech. This was big news. The new Pearl screen is a notable improvement on Eiink's existing Vizplex screen. The contrast is better, and the white is whiter. But I want to point out what the screen is not: COLOR. I missed this in the original announcement, and so did everyone else.
When I first posted this news I noted that E-ink were not resting on their laurels. This is true, but they are still a step behind everyone else. Liquavista are promising to have their color screen on an ereader by the end of the year. Qualcomm have also been quite emphatic about their Mirasol screen; they won't say who will use it but it will be out this fall. And those are just the ones that making device promises. Fujitsu had the FLEpia ereader on the market last year. Bridgestone have a color screen ereader about to hit the market (distributed by Delta Electronics). Where are E-ink in all this?
When it comes to color screens, E-ink are not a serious competitor, IMO. I looked this up, and they first demoed their color screen back in 2005. Check the press release. (I have to admit that I was a little surprised.) I don't think we're going to see a color screen from E-ink, not ever. They had a demo 5 years ago and have never actually released a device. My guess is that there is a technological reason for the delay. I don't think E-ink can do a color screen with their epaper technology.
If they could make a color screen, don't you think they would have by now?
