What is the difference between a data projector and an overhead projector?
A Data Projector (referred to as Digital Projector) is a projector that gets its image from a Digital Source, such as VGA (computer), RCA (the most common A/V input), S-Video (another form of video input), and some others. These projectors are most commonly used along with DLP or LCD Technology.An Overhead Projector is an older style of projection, common in Education (Schools). These projectors are totally manual and require you to put a transparent image onto glass to project the image overhead.
What is overhead projector and projector?
An overhead projector is used to project an image of a transparency onto a wall or screen by means of an overhead mirror. There are also "slide projectors" that are used to display photographic slides on a wall or screen. A "projector" or "digital projector" would be used similar to a computer monitor or a television screen that would display an inputted image from a variety of sources (blu-ray player, computer, laptop, dvd players, game console, etc.). In the case of a projector the image is projected with the help of a light apparatus shining through a small silicon ship and projected through a lens to create an image on your wall or projector screen.
