MojoKid writes "Reportedly, Asus will be introducing the DR-570 color eReader by the end of 2010, but it won't be just another one in the crowd. In fact, it just might be a game-changer. The reader will supposedly have a 6" screen, but rather than using e-ink like every other reader out there, this one will utilize a color OLED screen. Word is the unit will last a whopping 122 hours on a full charge. It should also be able to run Flash applications, download books over 3G to Wi-Fi, and most likely surf the web, unlike any other reader out there." Asus will be rolling out two other ebook reader models this year as well.

    122 hours on full charge? Really?

    Does anyone have any information to back this up? OLED screen power requirements etc?

    In fact, it just might be a game-changer.

    Okay...

    The reader will supposedly have a 6" screen, but rather than using e-ink like every other reader out there, this one will utilize a color OLED screen.

    According to Wikipedia [wikipedia.org]: " OLEDs typically produce only around 200 nits of light leading to poor readability in bright ambient light, such as outdoors "

    They're proposing that an OLED E-Reader which cannot be read properly in sunlight will be "game changing". Forgive me for being not quite so optomistic.

      I saw this a few days ago, and it sounds like a nice tablet machine. If it's hackable then I'd be very interested in one, especially if I can use it with a Bluetooth keyboard. As an eBook reader, it sounds pretty poor.

      Of course, that's assuming that it just has an OLED display. One thing I've been hoping for for a while is a hybrid with eInk under transparent OLED. You'd designate different regions of the screen to the different displays, so you could have colour images and videos in boxes on a text page. For something like a web page, most of the text would be rendered on the eInk display, but videos and images would use the OLED, unless you were in low-power mode, then videos would be disabled and images would be converted to greyscale. Touch a button and it would make the eInk black under the image and use the OLED to show the picture.

        With the ability to alternate between a black-and-white as-readable-in-direct-light-as-eInk mode and a standard color LCD mode, both with fast (normal LCD) refresh rates, and cost to manufacture on par with current LCD displays, this technology is the future of tablets (which will subsume the eReader market). And the first product, the Notion Ink Adam, is coming out this year.

          Exactly. I got a good laugh out of that claimed 122 hours of runtime. Not with the screen showing anything it won't. Yes OLED has some important advantages over LCD but not that great. Unless it is going to have a huge ass battery pack sticking out current battery tech won't light up the screen for a hundred hours. Can't avoid the reality that emitting light consumes power. Of course there are ways to cheat the spec. Only light a small percentage of the pixels at less than full brightness

            Thats true - but why must it emit light? - using reflective technology you can achieve significantly less power needs. as well as being able to read in sun light - it is also the most natural way of looking at anything (not just video screens)
            Case in point: the gameboy --its Display spec was : "Reflective LCD 160 × 144 pixels"
            http://en.wikipedia.org/wiki/Game_Boy#Technical_specifications [wikipedia.org]
            of course - it would be best to have back lighting for when you are in the dark too

      I'm trying to figure out whether that's a clever pun (since we are talking about visibility in different light conditions) or just a typo...

    The point about e-ink is that it's passive. It doesn't emit light. That's what makes it very easy to read for extended periods. Throw that away and you might as well go back to reading books on your laptop.

      I agree with your point about the passivity of e-ink (and I'm a kindle user), but I think it is also important to note the distinction between people who read, and people who look at the pictures (say, in Elle). There's probably room in the market for both products, and they may not experience too much conflict in user communities.
    • Well, that and the screen doesn't have to refresh. I absolutely love reading books on my Nook, and I have found that I tear through e-books much faster than paperbacks. I know for a fact that if I had to read on an LCD or OLED screen even, I wouldn't be able to read for extended periods of time, and I would just go back to reading real books...

        Well, that and the screen doesn't have to refresh.

        LCDs dont refresh. Please let that very tired meme die. Next meme up to bat, "e-ink refresh rate".

        http://en.wikipedia.org/wiki/Refresh_rate#Liquid_crystal_displays [wikipedia.org]

        http://en.wikipedia.org/wiki/Liquid_crystal_display [wikipedia.org]

        "Refresh rate: The number of times per second in which the monitor draws the data it is being given. Since activated LCD pixels do not flash on/off between frames, LCD monitors exhibit no refresh-induced flicker, no matter how low the refresh rate."

        Sure that was an appeal to authority, quoting wikipedia. But lets think about it, a CRT flickers because an electron beam sweeps a fast decay phosphor. LCDs don't have a "sweeping electron beam" or a rapid decay phosphor. I suppose you could simulate a flickering CRT using an LCD by updating the entire screen at 120 Hz and alternating data and a black field.

        If your eyes hurt looking an "old fashioned" LCD but feel great looking at a "new expensive" e-ink, then you probably have audiophile-itis, easily cured by following solutions:

        1) Green marker around the perimeter of the LCD

        2) Install the LCD in a $3000 brushed aluminum enclosure

        3) Use monster cables instead of cheap interconnect cables.

        Alternately your eyes might hurt when you look at a LCD screen because your eyes are screwed up. See an eye doctor before you go completely blind.

          LCDs dont refresh. Please let that very tired meme die.

          Er, yes they do. You've misunderstood the actually quite explicit wording of the wiki article. They don't flicker due to refresh, but they sure tear/judder/blur due to refresh. Do some acid and/or shrooms and tell me you don't notice the diff between 60Hz and 120Hz. xD

          However, this is not directly relevant to an e-reader, unless it is being used for video.

          3) Use monster cables instead of cheap interconnect cables.

          You're right that it's not caused by a refresh rate. What is causing it is that CRT/LCD/OLED screens emit light, while eInk reflects it. Doesn't mean there's not something wrong with your eyes (astigmatism or glaucoma causing blurring or halos, for example), but the emitted light is the reason doctors suggest you take frequent breaks when looking at a screen (TV, computer monitor, etc) for a long period of time.

          • by ceoyoyo (59147)

            Adjust the brightness of your screen. It doesn't matter whether the light is emitted by your LCD or reflected by your e-ink, so long as it is done so in a reasonable ratio to the intensity of the ambient light. Light is light.

            Reflected light automatically adjusts itself to the ambient. An LCD screen can do this as well, but requires a sensor. Failing that, you can use the backlight control, often labelled as "brightness" to adjust it manually.

        • by adolf (21054)

          Just because LCD monitors don't refresh like a CRT does, doesn't make them perfect.

          I had a Viewsonic VG930M 19" LCD, which was an absolutely lousy monitor. Certain colors and shades would be very obviously and visibly noisy, due to the dithering used to approximate colors which the display was incapable of producing. (This is mentioned in your linked Wikipedia article on LCDs, down under the Drawbacks [wikipedia.org] heading.)

          For a demonstration of this and some other problems with these displays, head over to this handy

          • by sowth (748135) *

            The flicker on LCDs is apparently because they use pulse-width modulation to vary the output level of the backlight in a power efficient manner. Yet the frequency is hideously low, so you can see it flicker. I am not sure why they don't use frequencies in the kHz instead of Hz range. The electronics should be able to handle it easily.

            • by adolf (21054)

              There's that problem, too. And it's a dumb problem to have: The inverter driving the backlight tubes actually becomes cheaper to produce, the higher the frequency is.

              But please do go visit the LCD test page I previously linked before you start with absolute statements like "the flicker." There's a few things that they often get wrong -- sometimes, very, very wrong -- and you'll be able to see some of it there with your own eyes.

      No, that makes it harder to read. One of the primary advantages of eink is low power consumption and that goes away with a backlight. Therefore marketing pushes the crazy idea that its easier to read something thats all dim.

      Anyone who knows anything about photography knows its easier to focus on a bright light due to smaller pupil size.

      Its just endlessly repeated marketing BS.

      • I for one will go for the battery life and color over eInk. Though I've been using a netbook for about 2 years now, and plan on switching out for a low-power 12", not so much for the screen size, as the Atom is just a tad bit too slow. If it can't do flash reasonably, then web surfing suffers, if it can't display 720p video, or downsized 1080p, then my media suffers. All around, other than email, music and some browsing I don't use my netbook so much at all.

    We know the technology is there, and Apple only releases new product lines to be game-changers of existing product categories. What could be game-changing about a simple tablet PC? Many other are offering them now. A highly usable full-color e-reader in early 2010, on the other hand...
