If you are going to be buying a projector, it may be of use to you to know the different kinds available. There are three main projector types; CRT, LCD and DLP.
CRT (cathode ray tube) projectors are the original and, arguably, still offer the best picture. CRT projectors use three large tubes to project the image, in a way similar to your TV. Even entry-level models are expensive so, as this is an introductory article, we’ll leave CRT projectors here.
LCD (liquid crystal display) projectors are normally small and light. They work on similar principles to the LCD computer screen you may be using to read this article.
DLP (digital light projection) projectors are the up-and-coming technology. DLP projectors use thousands of tiny mirrors on a small chip, along with a spinning color wheel, to project the image. |
