Magic Lantern
These were the first projectors, capable of projecting images from frames. They could display still images, but were improved on to create a primitive slide projector. They were made up of a lens, a light, an some kind of painting or glass slide to display images from. http://www.magiclantern.org.uk/history/history01.php -
Opaque Projector
The creator of the opaque projector is undocumented. The projector is made up of a system of mirrors and lenses that project a brightened image of an object placed on the projector, all encased in a protective shell with a lens to enlarge the projection. This was improved by adding a digital screen to display digitally stored images. This was mainly used for teaching to display papers. Source -
Slide Projector
The slide projector was designed to display moving images. It was produced by Kodak, but was created by Louis Misuraca. It is made up of a light, lenses, and a carousel-like roll of 35mm frames(slides). It was manufactured by Kodak. It was used mainly in homes to look at pictures.It was eventually replaced by digital projectors, but opaque projectors were used up until their creation, and beyond.

Overhead Projector
The Overhead Projector was created by Jules Duboqc. It was a redesign of the Opaque projector. It is made up of a large light, a lens, and a mirror. It was created to be used in schools, which was where it was exclusively used. This was eventually replaced by digital projectors, but was in use for a long time in schools. www.americanhistory.si.edu/mobilizing-minds/overhead-projectors -
Digital Projection Panel
Before truly digital projectors were made, digital projection panels were used as a means of displaying images from overhead projectors. They were made up of a LCD panel, controls, and a metal case designed to be placed on overhead projectors. This was also used in schools to display images that were difficult to print. http://www.projectorcentral.com/projectors-evolution.htm -
Computer Projector
This was created to combine a digital projection panel, and a projector into one machine. This was designed for use in schools, businesses, or other educational settings. They were compatible with most computers , and were capable of displaying only one image at a time. these were then further developed on to create video projectors. http://www.projectorcentral.com/projectors-evolution.htm -
Video Projector
These were an improved version of the computer projector. They were capable of displaying digital video, which was something that all previous projectors were incapable of. While these were fairly bad quality, they laid down the basis for the modern multimedia projector. These were made up of a lens, and a display system for projecting the moving video. These were used in both educational, and home settings. http://www.projectorcentral.com/projectors-evolution.htm -
Multimedia Projector
These are a more advanced version of the video projector. It is capable of displaying any media that was sent to it digitally. Most models use a series of lenses, but some newer kinds use lasers. These are in use everywhere nowadays. They can be used for educational purposes, or for home use to display video. This was later made smaller into a pocket projector, but those pocket projectors are not in use. http://www.projectorcentral.com/projectors-evolution.htm
