Motorola Debuts Nano-Emissive Flat Screen

Posted by timothy on from the when-will-it-open-its-flower-to-us dept.

brain1 writes "PhysOrg is reporting that Motorola has developed a 5" flat-screen prototype display that uses carbon nanotubes. The display appears to promise lower costs for a full 40" HDTV screen bringing the price down to $400. The technology uses standard color TV phosphors, has a response time equaling CRTs', all in a package 1/8" thick. The display characteristics meet or exceed CRTs', such as fast response time, wide viewing angle, and wide operation temperature. All these are areas that LCDs are weak in. Is this the breakthrough we needed to finally make HDTV and flat-panel computer displays *really* affordable?"

    LCD gamut is not poor because it is digitally driven. It's poor because LCD is a backlit technology.

    When an LCD screen tries to show "black" a large portion of the backlight is still showing through. Moreover, this varies across the screen.

    This is an emissive technology using the same phosphors as a CRT. Banding might be a problem, but it's insignificant compared to the color range problems on LCDs. Banding is tolerable in many applications. Shimmering and lack of contrast is not. Most LCD manufacturers don't push to avoid banding because the contrast problem makes the LCD unsuitable for color sensitive work anyway.

    In fact, this should get *better* range than a CRT, because any cell can turn completely off. Any but the highest quality CRT has a problem with rise time and such. The brightness level of parts of the image affect other parts.
