Who needs video, eh? By that logic, who needs e-ink when we have paper?
Colour would be nice too.
Semi-rugged won't happen. (Just look at iPhone.)
We use these devices instead of OLED display devices such as current tablet devices due to lower power use and the clarity of a non-backlit display, not because we're desperate to never see so much as a frame of video! Oh, and to read books. Reading books is good

As for the demo shown: why quarter size video?..

I think what we really need is more durable E-readers like having: water proof,scratch proof and drop proof, they make cell phones like that so why not readers?

Colour(color) would be cool but really not that needed unless you read allot of mags on it.

Well, if they get eink color, with good color definition (of course that won't show up in next weeks, but washed colors is a start) they can expand the whole eink market beyond readers. Publicity indoor, graphic designers would love to have angle-variation-color-prof display to work at, people who spend their entire work time in front of a computer (I'm sure that this is alsoa eye-straining task), if we start to think beyond books I bet there are a lot more applications to a color eink display that can play videos, and i can see even myself moving to a lower refresh rate to release my eyes from lcd (and save loads and loads on pre-printing everything to check colors).

Again, it's not there yet but u need to learn 1+1 before analytical mathematics :P.

How much more would you be willing to pay for one? Durability costs.

The color eInk I'm aware of is based on designs eInk first announced back in 2006. It's 12 bit color. For many applications, that will simply not be adequate.

Quote:

Not based on eInk's color scheme, they wouldn't. You need accurate color. (I've been a designer in the past, and keep my hand in with occasional side projects. Color eInk would not do here.)

Quote:
people who spend their entire work time in front of a computer (I'm sure that this is also a eye-straining task),
Oddly, most folks who report eyestrain trying to read ebooks on LCD screens do not report it for normal use, like browsing MR.

I don't consider myself representative, since I've spent the majority of the day staring at a computer monitor since well before LCD screens became the norm, and have had no problems. My standard ebook viewer is a PDA with an LCD screen.

Quote:

Good luck on the latter. I really don't see color eInk achieving the color required. And you still need to do test prints for any designs that will be printed. Ink on paper is different from colors on a screen, and the second is only an approximate guide to how the first will look.

The question is whether it ever will be there.

I was just reading an article on EETimes where Xilinx CTO Ivo Bolsens was talking about FPGAs as integral parts of an SoC strategy.

Of course, "Simple" in Simple Matter Of Programming is relative.

But yeah, off the rack, though I don't see Bookeen using it as a video controller.

Oh, it will. Pocketbook has a few models in their lineup, they just can't get the panels in significant numbers yet. They are aiming at the educational market, amongst other things, where a glass panel really won't do.

Really? I would have more thought it a matter of getting the design right in the first place. Use WLAN/UMTS only and an inductive charger and you pretty much have a sealed-off waterproof case. Add one of the new "plastic" eink screens once they become available in numbers and there you are. Not exactly rocket science. But, yeah, I'd pay a premium for such a reader.

Quite impressive to see what they've done with the eInk display to get the video, quite impressive indeed.

Not something I'd need on my reader. But nevertheless very impressive, that's certainly true.

Nice to see Bookeen still at work and trying to get PR. Good for them.

It's actually displaying a "feature" of E Ink: Partial screen refresh. Only the quarter needs to be updated (which I assume requires less power), while the rest of the picture can remain stable.
