Questions about projectors - Engineer project (1 Viewer)

[ChampionDK]

Hi!

I and five other engineer students at Aarhus University, Denmark, are currently doing som research on noise made by projectors. The goal is to reduce or potentially eliminate the noise.

We have some questions, and we would appreciate if you took the time to answer these.


1. Which type of projector technology is the most popular right now? (LCD, DLP, CRT, LED etc.)

2. Will we see any new tehcnologies soon? If so, which?

3. Is noise level an important factor for you, when purchasing a projector?

4. Would you be willing to pay 2-300 USD extra for a projector with a significantly lower noise level?

5. Is it only the light bulp that gets heated, and therefore needs cooling, or are other components in the projector in need of cooling?

6. How hot can the bulb get before it breaks down? And at which temperature is the bulb kept to secure it from breaking?

If you can't answer all the questions, just answer the ones you can.


If you know of any other forums where people would be able to answer the questions, or if you have a lot of knowledge about this yourself, please let us know.

Thanks!

1. Right now, for front projection (you didn't specify,) LCD and DLP are the most popular (by sales.) Presently, LED-based projection uses an LED light engine (lamp) to drive a DLP imaging engine.

2. Future technologies right now on the horizon seem to be various interference engines (Silicon Light, among others, I believe) and laser-based imaging systems, which I believe are holographic/interference type engines.

3. I would imagine that noise-levels for home projectors are mostly under control - most of the
