This is the predecessor of the digital overhead projector considered as the replacement within the 21st century. Before, the projector had a large box that had a bright lamp, where a fan was installed for its cooling purposes, then on top of the box, there was a lens which normally transmitted the image that the box was illuminating then bounced it back to the screen that could have been either a white curtain or a white painted wall, however nowadays, they are now using a tarpaulin.

The technology of an overhead projector during the olden days is very simple and might say crude as well during those times yet still causes projection compared to the modern day LCD or DLP projector. In the modern day counterpart, they use an arc, which is brighter and more durable than the conventional light bulbs that they used before. The only setback to this technology is the warm up time it takes before it can project the image. But when it comes to its versatility, it is truly adaptable to every medium. It is capable of being connected directly to your desktop, laptops, camera or any video player in which output is being transmitted by your ordinary RCA jack connection or USB connection, which is the universal type connection. With that capability, it eliminates the tedious task of transferring your presentation from one type of material to another in order for the projector to display the images that you are playing for your audiences.
