Philips Working on LCD TV Ghosting
agentfive writes "Philips is working on a new lamp technology to eliminate ghosting. Ghosting is a problem in LCD TVs when tiny pixels creating the image take time to switch on and off and can't do it fast enough. The problem, widely recognized as the main drawback of LCD TVs, is apparent in fast moving objects such as tennis balls, but even slower moving images get fuzzy. Philips will do something similiar to a Cathode Ray Tube (CRT) by switching the fluorescent backlight on and off at a rapid pace."
This is the primary reason I would never buy an LCD TV. If they can fix the ghosting problem, I'd really appreciate it if they license their solution to other companies, rather than hoard it for themselves and pump up the prices, claiming that it's some sort of "XHDTV" or some such crap.
I am scientifically inaccurate.
"Remove one of the advantages of LCD screens, why don't you?"
You obviously missed this. It will only turn off and then on again if there is a color change. WHAT A CONCEPT TO TAKE IN?
While the pixels adjust their color, the backlight is off, and it will only switch on when the image is ready

I wanted desperately to love the LCD monitors. They are not as hot, they don't take up as much desk space, less danger of radiation and they have very sharp pictures. I do a lot of audio and video editing and computer graphics, and I do get into a game of Soldier of Fortune or Halo with my kids now and again - so I bought a 19" Dell that promised it was very fast on the refresh so it would be great for games. I tried it for a couple of days, but I had to return it because it made me carsick all the time because of the "ghosting/motion blurr" stuff. Before returning it, I went on a quest to every store with these on display and every one that belonged to someone I knew and found that all I needed to do was a few simple tests like moving the mouse cursor across the screen to see that they ALL had streaky blurrs following every dark thing that moved. The higher the picture quality was the blacker the blacks seemed to be and the blacker the blacks got the more exaggerated the blurring was. The higher the picture quality settings in the games were, the worse the blurring looked as well. I also noticed that on a screen any bigger than 15" the screen always appeared to be lit unevenly, depending on the angle it was set at, where I was seated and whether I was slouching or sitting up straight. Some were much better than otheres, but they all did it to some degree. I always had to move my head around to see how something full screen looked. I bought a 21" Philips CRT monitor for less money and am much happier with it. I have been looking at computer monitors up to 20 hours a day since 1989, and I solved the flicker/eye strain problems of CRTs years ago by just getting a monitor that supports 100+ refresh rates. Another HUGE problem with LCD monitors is that they only have one resolution available where the resolution is sharp and clear. I never saw any warnings about this very serious problem anywhere "before the purchase" although I found quite a few people who became aware of it after they bought their LCD panels. If you set them to any resolution except their "native resolution" the picture is extremely grainy and fuzzy, and the colors are way off. I don't like having to use only one resolution and only the one they decide I should have. My son's laptop computer has a native resolution of 1600 on a 15" monitor which is really too small for a normal person. If he sets it to anything else the picture quality is really bad. I think the flat panel monitors are all right for doing static work and ok for that up to 17." I use one at work like this and although I am always having to adjust the angle depending on if I am standing or sitting to see the picture well, It suits my needs well because it fits on a counter top where a regular monitor would not. I really think it is good that people have choices and can use whatever best fits their needs. I expect to be using only flat panel monitors eventually when the technology improves. I say let them try anything they want. There is no danger that a bad technology will take over because nobody will buy them if they are that awful. The manufacturers will make what people are willing to buy, so let them experiment. Maybe they will eventually come up with something we can all use.
