The Development of E-Paper Technology 117

Computerworld takes a look at the development and the future of e-paper. Brought into the mainstream by e-book readers such as the Kindle, e-paper is rapidly becoming its own industry. The article notes some of the current limitations of the technology and looks ahead to a few of the upcoming ideas, such as the Fujitsu Fabric PC. Quoting: "The resolution of EPD screens is improving rapidly. Active-matrix displays like those used on the current generation of e-book readers can work at relatively high resolutions (the Kindle screen displays 167 pixels per inch), and Seiko Epson recently showed off an A4-size (13.4-in.) display prototype with 3104 by 4128 resolution, about 385 ppi, that uses E Ink's electrophoretic ink on a Si-TFT glass substrate."

    The biggest challenge is that ebooks still cost almost as much as paper books, and distributors still take more than 50% for simply having the files on their servers. This is to be expected from Amazon, who make most of their money selling paper books, but I think I will wait until some independent alternatives come up selling cheap ebooks, and giving 90%+ to the authors.

      I'd agree, but at this point I dont think the appeal is price. Its partially the coolness, like a nerdier iphone, and partially the convenience. I'm a student and move around a lot, so being able to keep a large collection of paperbacks without the necessary bulk of boxes is really appealing; of course, you still want real dead-trees for textbooks and such.

          I think lack of sales, if that was an issue, are probably a supply problem rather than demand. Anyway.

          There are tons of shortcomings with the Kindle that prevented it from being as popular as the iPod. Unfortunately it doesn't look like Amazon really looked for input before launch. Frankly, I heard about it less than a week before it was launched. The lack of hype probably didn't help, but there are problems with the device itself.

          1) Books are less popular or "cool" than music. Books are not "status symbols" unless you're trying to look well-read... and then it'd be better to have a bookshelf of leather-bound tomes.
          iPods play music (which can be passively consumed for a long period of time and thus has more apparent value)

          2) A good portion of the books that people want to read will never be available on the Kindle.

          3) It's difficult to put the books you already own onto the Kindle.
          Music CDs (and other formats, with some effort) can easily be transferred to an iPod. iTunes made a large library of music available.

          4) The Kindle is not cool looking. It has too many buttons, it looks a bit cheap, the screen can't be appreciated from photos.
          The iPod is clean, distinctive, and simple-looking.

          5) The Kindle is only available online from Amazon. That is, when it's not sold out -- which it was for months after launch.
          The iPod was hard to find for a while, but it was available from many retailers right away.

          6) The Kindle doesn't support Wi-Fi; instead it works off some cellular network that few people really understand, which is only available in the US anyway.
          The iPod just plugged into a computer using a cable or dock. Maybe technically inferior, but easier to understand.

          7) Kindle is only available in the US. I'd totally buy one if they were available in Canada, but they aren't. EBooks have the greatest appeal where paper books have the least availability.
          The iPod was available everywhere. I think it only supported Macs at first, but that was soon rectified.

          8) The Kindle is limited somewhat in file format support. Notably, they don't support PDFs natively.
          For music, MP3 is the only format that really matters. Apple did co-promote their lossless format, and that probably helped them.

          9) Buying a Kindle to read books is not economical for light readers. The device itself costs $400, and if a Kindle book costs $10, and an "average" real book costs $20, you'd have to buy 40 books just to break even. Except that some books will not be available for the Kindle anyway, and you'll have to buy them as paper. (The majority of books I buy, for instance, have photos, diagrams, or illustrations, or are textbooks that are not available in digital formats.) When the Kindle breaks or becomes obsolescent, the books become useless. (Of course, it's still not a bad deal if you read a lot of novels, or want to download newspapers.
          Music needs a player anyway, and an iPod is smaller than a portable CD player or a stereo.

          10) The Kindle lacks storage space. It's expandable, but what does it have again? 128MB? How much does a 1GB stick of flash memory cost again? $10? (Of course, text-format books don't take much space -- but pictures, comics, or podcasts do.)
          The iPod had 5GB of memory, enough for many albums and even a modest music collection.

          11) The Kindle is too large to fit in a pocket and too small to display letter or A4 sized documents. Even if it did support PDFs. It's about the size of a paperback. That's not horrible if you're reading novels, but it's not optimally portable, nor optimally useful.
          Even the original iPod fit nicely in a pocket.

          12) Kindles weren't hyped much and lacked branding. Amazon isn't known as a tech company at all -- they're known as a bookstore.
          iPods had the force of the Apple community behind them. Apple is known as a superior tech company.

          I'm positive that availability was the biggest obstacle, though. How many people would have bought them if it was as simple as going to Best Buy?

          It'll be interesting to see what will happen with the first e-paper reader that gets into stores.
          • You make many valid observations. I will point out, however, that Sony's e-book reader has indeed been available in stores -- you can find them at Borders for instance, and for $60 - $100 cheaper than Kindle -- but it has not taken off the way that the Kindle has.

            I'm not Kindle's biggest proponent -- I actually had one but returned it -- but Amazon has gotten enough right with the Kindle to make it the first VIABLE e-book reader out there. Its early success is what will make a Kindle 2.0 commercially poss
        • On what basis can you say that "Kindles are selling like Zunes"? For months, the Kindle was back-ordered; it wasn't until about a month ago that you could order one with the expectation of having your order promptly filled.

          Sales of the Kindle, in terms of absolute numbers, may still be fairly modest, but it is hands down the most successful e-book device that's ever come to market. It's a far cry from being the "Zune of ebook readers."

        I'm a student, too. I also do a LOT of traveling. And I own a Kindle.

        I will say this: why would you want paper textbooks when you can have a textbook that allows you to do a full-text search? Also, you can make plenty of "margin" notes. And highlight a row and look up words or Wiki any term you see in there to get a (very rough but generally sufficient) bit of info on anything in a text that makes you curious? Most textbooks are horribly indexed in my experience - full-text search makes that irrelevant.

        As for getting books cheap, how does "free" grab ya? I've been downloading tons from gutenberg and other sources like that, there are MANY places that allow you to get a bunch of books for free (legally) and of course, torrents to get them (not as legal) for free as well if you don't have qualms about that. It is trivial to convert from one format to another with free software and, really, the DRM is, as usual, only a minor speedbump for anyone who wants to circumvent it.

        I do think the $10 for a "bestseller" type book is way too much for this kind of thing, but I don't really read a lot of those. There are plenty of ebooks available for less, though - $9.99 is the high. I've bought maybe 10-20 books through amazon and spent a total of $15 or so, give or take a few cents. I've used both the amazon paid and free conversion services (the difference is that the paid one takes your document from whatever format to the AZW format and sends it directly to your kindle for ten cents while the free version just emails it back to your address and you have to manually load it onto your kindle) and it has been great.

        Would I have bought it if I hadn't been given it as a gift? After using it quite a bit, I can say hell yeah. This is the kind of thing that people need to use for awhile and see how it works before they can see just how useful a tool it is. If they had these available for people to play with at bookstores they'd probably sell quite a few more.

I find most of the books I buy to be greatly underpriced for what they contain, so I really wouldn't complain about having them in a convenient format *and* at cheaper prices.

            Marketers love people like you. Heck, why shouldn't they? Who wouldn't like to be able to price their product solely on perceived value rather than on production costs plus a reasonable profit?

            Like, back when they shifted from LPs which cost $2.00 each to make and sold for $8, to CDs which cost 50 cents each to make and sold for $15... and it worked, people bought it, people accepted the higher price, the cartel-created massively higher profit margin.

            Man, with customers like that, the sky is the limit as far as profit margins go.

            Instead of making a book for $2.00 and selling it for $10.00, they can transfer the file for a fraction of a cent and charge $9.00. Huge increase in profit margin. And sell you a book reading device for hundreds. AND eliminate the used book market. And eliminate library borrowing.

            And have you thank them for it. Damn, this "intellectual property" thing is a great scam.

              And have you thank them for it. Damn, this "intellectual property" thing is a great scam.

              And, as has happened in the music and movie industries, none of that huge increase in profit will go to the "artists", i.e., the authors.

              But this may change. The Internet has made it materially easier for musicians to reach their audience. Musicians can now set up their own web site, and completely eliminate the middlemen. There's still the advertising part of the business, but that never did much for 99% of the world's musicians anyway. Eventually this new distribution system may end up benefitting them.

              There are signs that authors are figuring out the same thing. There are a few authors that put their stuff online first, to get their name out there and build up a population of readers. They are figuring out that they can periodically publish their stuff and sell it to readers who have already read the online edition. There are small print shops figuring out that this is a source of business, just as there are small local recording studios and CD makers who will work directly for musicians and not take all the profits.

              The times, they might be a-changin'. But not in the eyes of the big publishers, who don't yet understand what's hitting them, and think that they can increase their profits without sharing with their authors.

      one of the big things a lot of people miss, is that public libraries are stocking e-book checkout systems. some of them even work with portable e-book readers. generally, libraries like to stock titles that people steal, or that people might be embarrassed to check out in person.

      it's pretty cool, and if you're not in a hick town like me, there are probably hundreds of e-books to be read all for free. I guess i just have to make due with project Gutenberg.

        Take the San Francisco public library. You can check out an ebook for 24 hours. No renewal. Forget about portable readers. And my guess is their vendor has locked them into this crappy system so they won't ever be able to change it. Well, at least til they discontinue it for lack of interest.

          Not quite. Typically the dots on a LCD screen are arranged as a 2x2 grid (blue, green, red, with doubled up of one of the colors... green?).

          So if you were only doing greyscale pixels, you could get approximately double today's LCD resolution (so around 250-260ppi).

        The OLPC isn't using e-paper, but a special display based around normal LCD screen, it is able to do 200dpi in black&white and has a sunlight readable screen, so its quite similar to e-paper in that regard. The OLPC screen is however, with backlight off, a lot darker then normal paper, so in-door it has some limitations in comparison to e-paper. The area where the OLPC however just flat out kills e-paper is refresh time, the OLPC works just like a normal monitor, so you can watch video, browse webpages

    The kindle is not an ebook anymore than a model T was a car, or an MP3 player circa 1999 was an iPod. In time someone will address all the concerns expressed here. For now I will say that the Kindle is extremely ugly and I won't reiterate its many deficiencies. Having said that though, I will say that the day of dead tree data is over. Killing a tree, grinding it into a pulp with poisonous chemicals, then packaging it with yet more dead tree boxes, shipping it thousands of kilometers with giant polluting trucks, storing them in the huge museums that some people call libraries or book stores, until they are worn out, and then packing them up in more paper boxes and burning them or burying them somewhere is beyond stupid - it is criminal. As far as paying 10 dollars for a book, this is theft, it is too much. The only true value of a book is in its IP. The ultimate goal is to cut profiteers like bezos right out of the loop. For those dinosaurs who still love the smell and feel of books you can always recycle by collecting some old newspaper and wrap your kindle in that. That way it will even dirty your fingers - just like a cheap romance novel. The kindle of the future will hold hundreds of thousands of books! And in no way will the paltry power requirements and this tiny bit of plastic be worse than all that trash. Besides it will be solar powered. Why do we still have newspapers? It is insane! Megatonnes of waste so some dino can get his sports scores! I do not think so. Think about students who will be able to download the latest textbooks for cheap - assuming that we can get greedy billionaire thieves like Bezos out the loop. Impossible you say? They are already doing it in Korea, a country apparently not crippled by the turgid thinking of stuck in a rut bibliophiles. A book is a terrible way to acquire data, you cannot look up a word, check a reference, resize the text, and you sure as shit can not read your email in between. In 20 years there will, thank god, be no books. Just like you cannot buy a ridiculous film camera anymore. And good riddance to an outdated, polluting technology. Oh, there may still be specialty books such as coffee table books and the like for a while, but even those will be superseded eventually by superiour storage and display technologies. I do not love books; I love the stories and the information. And I do not love the dry dead corpses of what were once living trees that breathed, shaded, and were homes for animals. Save a tree, save the environment, and buy an ebook, just not the Kindle, it is ugly and Bezos has enough money. Most of it stored electronically by the way, not on paper - yeuch

    You're moving physical objects around and that takes physical time, not like LCD displays that change the state of electrons.
    He obviously has no clue how an LCD works. The applied electric field causes physical movement of the liquid crystal molecules, affecting the polarization of light. Granted the movement is primarily twisting of the molecules, but that is definitely a form of physical movement, not a process in which electrons cause emission or modulation of photons.
