Projectors can serve as business aids or home theaters.
The terms "data projector" and "digital projector" both apply to a device that projects images from a digital source for viewing on a large screen or wall. Projectors use LCD, DLP, or LCoS technology to process the images.
LCD Projectors
LCD projectors split light into red, green and blue frequencies, according to ProjectorReviews.com. These frequencies pass through three separate LCD panels and then recombine in a prism for projection.
DLP Projectors
DLP projectors send their light to a single chip containing thousands of tiny mirrors. These mirrors modulate the light before passing it through a rapidly spinning wheel that selects the colors for the projected image.
LCoS Projectors
According to ProjectorReviews.com, LCoS, or Liquid Crystal on Silicon, projectors bounce the red, green, and blue beams off an internal reflector panel before sending them to a prism for recombination into a single projected image.
Applications
Businesses use projectors to display computer information in conferences, while home theater owners use them to enjoy TV and movies.
Leading Brands
ProjectorReviews.com lists InFocus, Panasonic, Epson, Optoma, BenQ, Sanyo, Hitachi, JVC, Sharp, Mitsubishi and Sony as the leading projector brands.
