Projector Torture Test: LCD versus DLP

An anonymous reader writes "A ten month torture test of five LCD and two DLP projectors shows LCD images deteriorate during extended use." Not surprisingly, if you run an LCD projector for 4000 hours, it deteriorates... of course, if you're staring at a projecter 8 hours a day, for 500 straight days, maybe you should go outside ;)

In other news...

most materials react in unplesant ways when exposed to 4000 hours of consistant bright light.

Here's a crazy idea...

The LCD isn't deteriorating after 4000 hours, your eyes are.

This may come as somewhat of a surprise, but not everybody has a cushy job that lets them get away with working 5 hours a day.

I spend most of my time at work staring at my desk, but it looks like I'm working. I do that for probably another hour after lunch too, I'd say in a given week I probably only do about fifteen minutes of real, actual, work.

How did they fair in the "drag them behind the truck, and dip them in raw sewage" test?

My old goldstar has yet to be beaten, but the MAGs have generally held a strong 2nd place.

and the "bright light" is really the paramedic's flashlight as he checks your ocular dilation.

outside n. that big room with the high gray ceiling (some also report a big room with a high blue ceiling and a bright yellow light, but these remain unconfirmed).

"I'm sure that could burn out a processor that would survive 8000 hours of activity without a hitch.

Never mind the processor - you find me an OS that will run for 8000 hours at 100% CPU utilisation!

Bugger - I've just remembered - Netware 3.12.

Oh well...

"OT: did any subscribers see the "Microsoft DVD standard" article that was posted in TMF? It caught my eye and I refreshed the main page and it was gone, replaced by this article. Do the editors revoke certain articles before they go live? Was there a major factual error or something? "

OMG! Are you saying they actually took down a dupe?!

Unless you're playing Halo on that projector, in case it's perfectly acceptable. :)

Actually, I can see a tiny bit of desktop icon burn-in on my otherwise-awesome Samsung 170T under certain, very obscure conditions.

This monitor is about 8 months old.

The burn-in effect is barely visible when I pick up the invisibility ring in Quake 1, of all things. It's completely unnoticeable under any other conditions.

So, presumably the FETs in an LCD are subject to uneven aging effects. Unlike the effects mentioned in the article, this definitely isn't a backlighting issue.
