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 ;)

Hmm this is actually very interesting

I work as a projectionist at a theathre. we have 19 cinemas, lately we change all of our slides projector to lcd projectors(pre show adds).

we also have a DLP project or aswell.

the company, actually the whole industry would like to switch from film to digital projection to save cost.

Guess who is pretty much the only player in HIGH powere digital technology, you guessed it TI. TI makes the DLP projectors we all enjoyed watching StarWars/Disney animation on. Now you say that some project running for more than 5000 hrs is never going to happen at your housse, or maybe at your office but consider this.

our current project with bulbs, can go for about 8000-10,000 hours before the bulbs needs replacement. so we got through about 2/3 bulb a years per projector.

but only switch the bulb.

now the problem is that if after 8000 hours we have to switch more than just the bulb

(which is the case when a digital project goes bad if you ever owned one)

then this could really hurt TI in getting the theathres to switch over.
