Multi-Media Projectors

Multi-media projectors are extremely useful if you are making a presentation to a large group or just watching a movie with the family at home. They can project a computer screen to a HD DVD and are available in a variety of resolutions.

Projector Types

The type of projector refers to the type of display technology used on the projector. LCD's use panels of glass. DLP's use thousands of tiny mirrors.

Standard LCD - These LCD (liquid crystal display) projectors have one panel of LCD glass that controls the three primary colors. 

These projectors are becoming less common in the projector marketplace, as polysilicon LCD and DLP projectors gain popularity.

Polysilicon LCD - These projectors control colors through three panels and are considered to be of higher quality than standard LCD. The projection through three panels allows polysilicon LCD projectors to have higher color saturation than a standard LCD projector.

DLP - DLP (digital light processing) projectors use a single chip with thousands of micro mirrors to modulate the lamp's light and project it through the lens. DLP systems are composed of over 400,000 tiny mirrors, which modulate light from a lamp and project the "modulated" signal out through the lens onto a screen (this type of technology is also referred to as Digital Mirror Device, or DMD). DLP projectors are one of the more common and newest types of projectors on the market.
