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."
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.

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.

Meanwhile Samsung is readying 8ms 19" LCDs for production in Q4 , 2004. 12ms LCDs produce almost no noticeble ghosting, 8ms should be even better at closing the gap to CRTs.
