Projection


Evolution of Projectors

Corporate America was first introduced to projection technology in the 1950s. Although the technology itself has changed dramatically since that time, conceptually it has remained the same. The opaque projectors which were the sole option of the 50’s have given way to a multitude of options in the 21st century where one’s choice of technology will likely hinge on the material to be projected.

Opaque Projectors - One of the earliest forms of projection, the opaque projector, allows the user to project printed material or small objects without having to convert them to another medium.
Slide Projectors - Slide projectors have also been around since the 1950's. Unlike opaque projectors, slide projectors require that the presented material be transferred to a 35mm slide allowing the user to project virtually anything that can be can put on film.

Overhead Projectors - In some ways an overhead projector is very much like a slide projector in that the information to be viewed must be transferred to another medium, in this case a transparent sheet of flexible material known as a transparency.

Digital Projection Panels - In the late 1980's overhead projectors found further use with the introduction of digital projection panels. The digital projection panel consisted of a large LCD, electronics, cooling fan, and a plastic or metal enclosure with a glass plate on both sides of the LCD

Computer Projectors - the fully integrated digital data projector came into existence in the early 1990's and served primarily as a computer display projector for business, education and training. It essentially combined the overhead projector and the digital projection panel into one device making it considerably smaller and more easily transported.
