Pixel Qi Says Next-Gen Displays Meet or Beat iPad 3 Screen Quality 157

New submitter seb42 writes "Pixel Qi announces new screens that can match or exceed the image quality of the screen in the iPad3, with a very low power mode that runs at a full 100X power reduction from the peak power consumed by the iPad3 screen. Hope the Google tablet has this tech." The claims are pretty bold, and specific: "We have a new architecture that 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."

    The original screens were in no way vaporware. I have three and love them all. (No, the picture quality is not on par with a normal screen, but the power savings and daylight use far far far outweigh that (minor) drawback.)

    Apple isn't using them because a) they're not out yet, b) they aren't mass-produced the way Apple needs them, and c) Apple has volume contracts for screens with its great friend Samsung.

    (Yes, the irony is real -- they are suing Samsung while simultaneously buying tons from them.)

    Well, except for having ridiculous (and I mean that in a good way) pixel density, that's exactly what Pixel Qi displays to date have all been about -- with one caveat.

    The problem, with a conventional LCD, is the color filters -- each one blocks out perhaps 70% of white light (you can block more for better gamut, less for worse gamut, but reduced light consumption). That means you get, at best, 30% albedo for your display in a white state, and that assumes your filter doesn't cost any extra on the second pass (a theoretical brickwall filter) -- real filters will lose some. So, ditch the color filters and win, but this makes your display black-and-white. Pixel Qi gets best-of-both-worlds capabilities by generating colors in the backlight (using a diffraction grating), allowing low-res (since you need multiple subpixels to make one pixel) backlit color display, or high-res (1 subpixel = 1 pixel) reflective grayscale display. That's the catch -- of course, with a powerful enough backlight, you can still make the colors shine through in daylight (though they will be washed out by the reflective light, reducing saturation), but then you don't get the power savings.

    They did it once.

    Sorta.

    You can buy their screens for yourself [pixelqi.com].

    There are a few examples of this screen out there but I think the reason it's so hard to get a hold of is that the current Pixel Qi screen, well, kind of sucks. The color saturation, contrast, etc just aren't that great. Turns out the screen isn't that good at any of the things it was hyped to be: good color inside, good b&w outside.

    Look for "Samsung" on the stock exchange. No, not NYSE or NASDAQ; they are only traded in Korea. And there's only one of them on KOSPI (the Korean stock exchange), under the identifier "005930". The rest is all wholly owned subsidiaries, all of whom belong entirely to the same master corporation and report to the same single CEO and Board of Directors. It's one company. All major multinational corporations work this way, and a lot of smaller ones do too. For example, most power companies work like this...there'll be a company that handles fossil-based (aka, coal oil and gas) power generation, another for nuclear generation (if applicable), another still for transmission and distribution...but they all roll up under the main organization.

You don't have to know how the computer works, just how to work the computer.
