In Focus Systems 480CX ElectroBoard LCD Projection Panel VGA 12V Color Display

The In Focus Systems 480CX ElectroBoard is a portable color LCD projection panel designed to sit on top of an overhead projector and display computer video output as a projected image. The panel receives a VGA signal from a computer or laptop and uses the overhead projector's light source to project the image onto a screen, making it an early and practical alternative to standalone data projectors. The 480CX was a product of In Focus Systems of Tualatin, Oregon, a company that was among the pioneers in computer presentation display technology.

Applications

The 480CX ElectroBoard belongs to the first generation of LCD projection panels — a technology that emerged in the late 1980s and early 1990s as businesses and educators began connecting personal computers to overhead projectors to display presentations, spreadsheets, and graphics to groups. These panels replaced hand-drawn transparencies and allowed a laptop or desktop PC to become a presentation tool for conference rooms, classrooms, and trade shows. In Focus Systems was one of the leading companies in this space before self-contained data projectors eventually displaced the panel-on-overhead-projector format in the mid-to-late 1990s. Today the 480CX is of interest to vintage computing enthusiasts, retro presentation setups, and collectors of early computer presentation hardware.
