Which is better DLP or LCD projector?

There are three main technologies used for projection – DLP, LCD and LED. DLP (Digital Light Processing) uses a chip made of tiny microscopic mirrors and a spinning colour wheel to create an image. On the other hand, LCD projectors use liquid crystal displays, have no moving parts and thus are generally less expensive.
