You may remember Pixel Qi, an ambitious display maker looking to provide users with brilliant displays that not only save energy, but which are actually readable in sunlight. Since we covered their 7" and 10.1" displays way back in May, the company has continued working, announcing in a blog post yesterday a new display which "matches the resolution of the iPad3 screen, and its full image quality including matching or exceeding contrast, color saturation, the viewing angle, and so forth with massive power savings." In the post, Mary Lou Jepsen, founder of Pixel Qi, goes on to explain the display's special low power mode which "runs at a full 100x power reduction from the peak power consumed by the iPad3 screen."


Of course, the new display's ratings in the table above are "proposed" and not quite official just yet. Still, Pixel Qi's claims sound fairly impressive, and it will be interesting to see where the company's latest and greatest display ends up in the market.

    I've said it on Slashgear and say it again here

    Hey GOOGLE buy this patent before apple does it first!!!

    I'm going to be honest; the original PQi is....not a pretty screen.  It does work much better than competitors in sunlight and bright conditions but....it is not a pretty screen. Color's are off, it looks pixelated.... and I don't know if it's the Adam or the screen but it often has imaging bugs here and there.

    • Michael Goff

      The screen used on the Adam tablets (i have one myself) was not as high quality as was promised/expected, but it functioned decently well.  The screen bugs/glitches that I have noticed all seem to be related to problems with the insurmountable number of issues within the Adam itself, including various hardware deficiencies.

    I am super excited about this tech, but I think the graph is either incorrect, misleading, or a flat out lie.

    Lets examine the facts:

    First Graph - Lowest Power Usage
    This graph shows that at the lowest power consumption the Pixel Qi uses essentially no power. This does not tell what level the screens were set to, or even if these are all at the same lighting levels, or at each unit's native lowest settings, whatever they may be. Just a point, why is the high res Pixel Qi using less power than the low res one? My guess is they omitted the actual value.

    Second Graph - Dark Room
    Pixel Qi displays are using far less than their competitors. Ok, this seems plausible.

    Third Graph - Light Room
    Now the energy savings begin to add up, and you can see why this technology could be great for increasing battery life. This also seems ok.

    Fourth Graph - Direct Sunlight
    In this graph it appears the screen has enabled Captain Planet/Superman mode and is drawing energy from the sun's rays. This graph which shows the iPad screens to be using tons of power (this sounds correct so far) and somehow the Pixel Qi is now using even less than was being used in the lowest power settings(That doesn't sound right does it?).

    My guess is that a girl in the marketing department does not understand spreadsheets all too well. My advice is as this news has gone viral (as tends to happen) quickly correct the error and contact the blogs to correct the misinformation.

    Or she should explain how they have discovered real life magic.

      You don't seem to understand how Pixel Qi's screen works. It -does- draw energy from the sun's rays - it uses the sun's reflection for backlight.

    • p3ngwin

      maybe it's not he "girl in marketing" that has the problem. my guess is you don't understand the technology you're talking about.

      have a look at the "NITS" (a measure of brightness) mentioned under the middle graphs, and notice that the graphs start with "low power mode" meaning backlight ON, then it tells you in the next graphs that the backlight is getting brighter until...

      ..you go outside and the backlight is OFF, meaning the PixelQI display is using the sunlight to make the display visible with NO BACKLIGHT.

      the other displays have to have the backlight ON and very bright to overcome the ambient light-levels, in this case the sun, to be viewable.

      Here, have a look at an older generation (black & white) PixelQI display for how it behaves in the sun compared to LCD's:


      here's another example in various light conditions including direct sunlight:


      now imagine that PixelQI display in full-colour and a 60hz refresh-rate, and you get an idea of how the brighter the ambient light, the more that competing displays have to get brighter to overcome the "light pollution". while the PixelQi displays benefit in brighter areas to make you see the display BETTER.

      hence the power consumption being inversely proportional to competing displays in sunlight.

      so yea, kinda like Captain Planet/Superman mode :)

        Ok fine, apparently I might be a complete and total jackass, but why does the high res screen use less power than the low res screen in the first graph?

        • Firehawkws7

          You seem to be the one who doesn't understand graphs. If you look at the key it says the lower res is currently shipping, meaning actual representation on the graph. The higher res is proposed, also it's newer tech.

    Its nice to see pixel qi still hanging in there but it seems they're still stuck playing with no name(or negative name) companies. They desperately need two things:

    1. A good brand name company to use their screen.
    2. IR screen so they can drop the glossy capacitive screens. Their screens are great in direct sunlight but when you have that capacitive layer reflecting the sun back into your retinas it really lessens that experience.

  • olbp

    Qi delivered the goods on their first screens with style. I certainly expect great things for their new screens. Hope they go mainstream soon, as outdoor use is one of my requirements for ANY screen, and apple just doesn't hack it.

    • Abbazabba

      GNex with a step above the lowest brightness is still eeeeeeeeasy on the eyes in the sun.

  • Deltaechoe

    I like the proposed specs but what I really want to see is how their claims stack up against the real thing.

  • cooldoods

    With these claims, Apple might be tempted to buy the company if they are able to come through though I think Apple is the type to want to keep their options open long-term.

  • warcaster

    I think they're really fishing for Apple here with that 2048x1536. Sad to see them crawling to Apple like that, especially when there's 0% chance Apple will agree to using PixelQi. The color contrast is way too weak and I doubt Apple will ever accept a display with a black and white mode anyway.

    Picaim is a project that aims to become a social network to see and share things that are happening in your city and in the world.
    The service is based on sharing geo-located photos of things that are happening in your city.

    The great idea is that photos can not be sent by the computer, just for mobile devices, and only at the moment they were captured. This measure helps prevent false information inserted in the social network.

    This means, you see what is happening, what the person who took the photo has to say, and where that is happening at the moment what is happening.
    You can see content classified by what is happening in your city.

    Also you can post anonymously, if you wish to protect their identity to share with the world.

    Anyone can see what is happening in your city on our web site, without registration or application for mobile.

    The project was launched this week, still has very few users, and we are asking for help to all who possess an android phone, just download the application, test and share with friends in your city.

    To check out the project, visit:

    The application for Android already available in the market!

    The big news here is the fact it has the same color saturation and contrasts as the iPad 3. Pixel Qi displays have long been notoriously washed out. This is BIG.

    Yes, I've heard of Pixel Qi -- they specialize in releasing cutting-edge vaporware, correct?
