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?

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

      Although the swivel base kept turning the display unit around in circles.

    "100 per cent or more"

    It is actually less than 0ms. The images will appear on your screen before your GPU is even done with it!

  4. Plasma Televisions are not ready for primetime. by John_Allen_Mohammed · · Score: 5, Interesting

    Sucks to be me. Bought a 42" plasma television 9 months ago and the brightness has dropped significantly in that time, probably a half of what it was when I bought it. Thats under heavy use, maybe 16-18 hours/day it's on. Anybody else here have the same experience ?

      ...or maybe your eyes are just tired of watching TV 16-18 hours every day in 9 months?

      Plasma TV's will only last around five years. During that time the brightness will continue to decline. This makes them great for outdoor displays/public events, since there is more chance of a unit being rendered inoperable through transportation/assembly than there is through normal use. The following paper has a graph demonstrating the decline.

  5. Better numbers by Spy+Hunter · · Score: 5, Interesting

    If the pixels can respond to any signal within 5 ms, that means the highest framerate that can be displayed without ghosting is 200 fps (1 / 5ms = 200 Hz). Which is more than you should ever need, and a big improvement on current LCD displays (a good consumer display has a ~20ms response time; 1 / 20ms = 50 Hz, not even 60 fps, but good enough for TV's 30 fps.)

  6. The Samsung 710T has basically no ghosting. by UranusReallyHertz · · Score: 5, Informative

    After days of agonizing between it and the 20 inch Dell, I bought the Samsung 710T and I am pretty happy with it. And I have never noticed any ghosting whatsoever while playing games like Far Cry and Doom 3 and watching movies like Hell Boy. So I think the Response Time is already adequate, at least on the 17 inch sizes.
