The Cathode Ray Tube; what you and I would call a projector; have been around for more than 100 years. The technology, invented by a German physicist, works quite simply. It uses a glass envelope, which has an electron gun within it and is projected onto a fluorescent screen for viewing enjoyment. If you were a child in America in the 1980’s you probably remember in math class particularly, when the teacher would turn down the lights and pull down the projection screen to display triangles or write numbers so you could all copy them down, this was the same technology in use.
Home projectors have come quite a way since their introduction over 100 years ago. While those units found in the schools may have looked 100 years old, the amazing advancements that have been made from projectors, particularly home projector units, in just the last few years is worth noting.

This will include digital picture-enhancing features as well as other features like high contrast ratio and a constantly adjusting unit, which eliminates the spacing between pixels and offers a smooth, film like quality.
Computer projectors are less popular in the home setting but are found in offices all over the place. These allow for things like group presentations with images that are able to pop up on monitors as well as a larger screen for demonstration effect. Also if you’re situated for a tele-conference these units are well suited to broadcast and receive images using the proper software.
