LCD Pixel Response Time Halved

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."

Plasma Televisions are not ready for primetime. by John_Allen_Mohammed · 2004-09-05 23:23 · 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 ?

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.)
