Edward J. Delp, a researcher at Purdue University is working with Philips to make a monster 140″ monitor using 4 projectors on a single screen.

The prototype uses four separate projectors to display a single image onto the large screen. Innovative software allows the four separate projections to be blended together so that no seams are seen between adjacent segments, joining the four images into a single picture with higher resolution than regular television sets. Other large-screen displays use separate tile-like segments to create one image, but the boundaries between each tile can clearly be seen.

“The Thomson display has no visible seams, even though there are four separate projectors, each one projecting a different part of a scene,” said Edward J. Delp, a professor in Purdue’s School of Electrical and Computer Engineering who has been involved in work to develop software for the new technology.

This particular display also includes a computer, which runs an algorithm that gets rid of overlapping regions between adjacent projections, eliminating the seams in the process.

Delp is one of the researchers who spearheaded the proposed 21st Century-funded project, which would be headed by Zigmunt Pizlo, a professor of psychological sciences at Purdue.
