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 ;)
According the to article, "TI and Munsell ran the projectors continuously 24/7, replacing bulbs as needed. Each projector was stressed continuously for thousands of hours."
There really wasn't much information provided on the methodology in this article. Did they leave just the one image or did it shift thru? Were any of the projectors shut off at any point (besides changing bulbs)? What were the conditions of the room/area in which the projectors were stored - ventilation, sunlight, etc.?
How many purchasers of projectors are going to use them non-stop? Just imagine such a stress-test of your Intel or AMD processor - 8000 straight hours of 100% CPU activity. I'm sure that could burn out a processor that would survive 8000 hours of activity without a hitch. The longevity of the LCD monitors may be much better than this implies -- which could be better tested under "normal" conditions.
My last thought is that I don't completely trust a "scientific" test done by a company to show the advantages of their own system.
I was taking one day at a time, but then several days got together and ambushed me. (from a Rhymes with Orange comic)
