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."

Great.

Remove one of the advantages of LCD screens, why don't you?

Replace ghosting for eye strain? No thanks

In other words, to fix a barely-annoying problem with LCD displays they're willing to get rid of one of the greatest benefits. I'd rather deal with ghosting than have to go back to the days of CRT eyestrain.

Three times worse?

Looks like it's going to be even worse, FTFA:

While the pixels adjust their color, the backlight is off, and it will only switch on when the image is ready -- three times brighter than in a normal LCD TV to compensate for the dark period -- before going dark again.

Won't this make the flicker, oh, I don't know, about three times worse? I realize it's three times an LCD, not CRT, but still that seems like it could cause Pokemon-style seizures or something. Like you said, thanks, but no thanks.

Good point, BUT

That's a case of solving a problem that affects less than 1% of the population (Your specific application where ghosting/motion blur is actually a problem, as opposed to 99% of the population for whom it's been solved adequately on any decent LCD made in the past 5+ years.) in return for bringing back a problem that affects 25-50%+ of the population (flicker-induced eyestrain and headaches are extremely common) and produces SEVERE health risks for a non-insignificant number of people.
