LCD Pixel Response Time Halved

Posted by Hemos on from the speeding-things-up dept.

kagaku writes "Japanese newspaper the Nihon Kaizai Shimbun (evil registration required) said that Mitsubishi has mastered a technology to improve the response speed of pixels on LCDs by 100 per cent or more. It's done this by getting rid of the afterimages on screens which known as "ghosts", said the newspaper, and invented a proprietary system called Dual Domain Bend. It cites unnamed sources at Mitsubishi saying that this method produces a response speed of one millisecond when power is applied and five milliseconds when the lights go off and the power goes down. That, the paper said, compares to up to forty milliseconds to switch pixels on and off. While the technique, when it gets to the manufacturing stage, will have immediate benefits for PC monitors, it will also help narrow the gap between LCD TVs and plasma displays, which have a quicker response speed. Here's a non-registration required link."

    doesn't a reduction of 100% mean it has been reduced to 0ms?

      response improved 100% procent, time wasn't reduced 100% i guess time was reduced 50%, however it's still early, so you can brag with numbers if you know better :)

      it is a increase of 100% in response time, aka a redution of 50%.

      If response time increases by 100%, they've succeeded in making it twice as slow.

      response speed of pixels on LCDs by 100 per cent

      Or speed, to be more precise. I don't know why this is so hard for everyone to understand.

      If I normally drive home at 30 MPH, and I increase my speed by 100% (to 60MPH), I will get home in half the time. So if the rate at which pixels change luminosity increases by 100%, the transition time will fall by a factor of 2.

    The pixel response time has been reduced by getting rid of ghosts? Surely that's an effect of the reduction, not a cause?

    100% work*time improvement - Everyone goes what?
    50% of the time to display - Everyone says what? then gets it.
    twice as fast. - Everyone says oh, OK.

    Each increasing easier to understand but decreasingly attractive to marketing droids.

    Sigh.

  4. Bragging with percentages by shoppa · · Score: 4, Insightful
    I've seen some games played with percentages:
    Product A costs 40% more than product B!

    Product B costs 29% less than product A!
    Both are true... A is $14.00, B is $10.00. The difference is the same arithmetically, but doing it fractionally only serves to confuse things (usually, confuse the customer...)

    Things get really out of hand when there's a factor of two:

    We are 50% faster than the competition!
    From this it's not too far to say
    We are twice the speed of the competition!
    Which then gets twisted further to
    We are 100% faster than the competition!
    It's that last step that's most dubious to me, arithmetically (or geometrically) there's no justification.

      "50% faster" means 1.5 times faster. "100% faster" means 2 times faster.

      Even this is not true! '50% faster' means 150% times the original, i.e. 1.5 times as fast.

      This is a common confusion, but it makes one hell of a difference. 'N% faster' means '(100+N)% as fast', because faster is always more than the original.

      It should be obvious that '50% as fast' is less than the original, but '50% faster' is more than the original.

      100% faster means twice as fast, not 2 times faster.
