Prototype Rollable Paper-like Display Ready Early

freitasm writes "A few months ago Philips promised a rollable, paper-like display in two years, but it only took them a few months to have a prototype ready. From the article: 'The Readius is the world's first prototype of a functional electronic-document reader that can unroll its display to a scale larger than the device itself. With four gray levels, the monochrome, 5-inch QVGA (320 pixels x 240 pixels) display provides paper-like viewing with a high contrast ratio. Once the user has finished reading, the display can be rolled back into the pocket-size (100 mm x 60 mm x 20 mm) device.'"

Earth: Final Conflict, anyone?

E:FC MCI "Global"

Yet another case of companies ripping off scifi inventions. The only difference is the EFC ones were badged MCI. And of course, the Philips ones are functional. :)

That having been said, I can't wait to pick one up!

Now all we need is a computer device like the ones they used in the movie 'Red Planet'.

This is the type of screen resolution for my Digital Reader, the resolution that made me send it back the day I got it. There's nothing paper-like about reading dot-matrix like resolutions. The eye doesn't adapt but instead becomes increasingly fatigued.

This technology may have some application for computer-like applications. I was hoping for e-books. This screen resolution won't cut that....

It all depends on the specifics of the device. I'ved used a Handspring Prism with a resolution of only 160x160 for years for an ebook reader, and it's great. I've gone through quite a few, especially from Baen

It ends up with a column width around that of an article in a newspaper or magazine, and is quite readable. Even when only using a limited number of colors (default fonts are only 1-bit) ti works well. I think much of it is due to having a white background. So the reflective properties and contrast of the display itself could make a huge difference.

Yes, but the difference is that producers of four greyscale monitors actually sold units which gave them money to do development to produce more capable monitors. These guys, on the other hand, are likely going to not bother trying to get sales until they have a 256 greyscale display and then they'll charge too much for it to try to make up their development costs and the technology will fade into obscurity.

Supply and demand.

Well mostly just that you can sell suckers (most buyers) a low rez 17" LCD screen and they don't know the difference.

Heck look at what prices 15" LCD TVs go for! You can get a 15" LCD Monitor for less.

And a computer with a TV tuner!

If they can mass produce it ...

It depends on application. If you had read the article, you'd have seen that they do not intend to market the thing directly, but rather

the Readius was created in order to demonstrate the viability of the rollable-display concept in mobile applications and to gain customer feedback at the IFA 2005.

There are things that could benefit from this kind of advancement, even at the current state of things: GPS devices, for example, and even cell phones: even though these days we're used to colorful thingies which can do everything but guarantee you can make phone calls, there some of us (*raises hand*) which want nothing more than the ability to make phone calls and write and read SMS. The ability to do it on a wider screen extensible on purpose would be an extremely nice thing. Think about a one- or two-lines display that can roll up to enclose an entire SMS or addressbook without the need to scroll.

Another major selling point could be the ability to stay 'on' the whole time while still sucking up less battery. How much battery is sucked up by current displays? After all, there is a reason why all cellphones have screen savers or at least the ability to choose for how long after the key presses the display has to stay bright. Of course you might not be able to use your cellphone or iPod as nightlamp anymore ...

While an extensible, always-on display could be a selling feature of some such portable device (oh yeah, did I mention portable music players?) it would still need to be priced reasonably. In-between the current B&W braindead displays and the current fancy color displays of phone-cams.

That's just nuts. You're disallowing people to demonstrate proof of concepts on the basis that it's not a marketable product? Not only that, but they *have* made a product, albeit a non-commercial one.

There are more reasons to demonstrate this than 'we can sell it'. By doing this they are not only getting feedback from potential customers and hardware developers but also cementing themselves as being one the pioneers of the technology.

If a company designed a new type of PC memory I would imagine they would build a prototype motherboard to demonstrate it to the professional motherboard manufacturers. They may not concern themselves with building the commercial motherboard as it's not in their expertise, rather develop business relations with motherboard manufacturers to allow them to embed it.

If you look at this picture the display actually looks quite readable with quite a few lines of text. I imagine in a few years they will double the pixels, increase the contrast and use font smoothing to make it all the better.

And I too have read ebooks on a smaller 320x240 display and found it easy enough to keep using 5 hours+ in a row during reading sessions.
