World's Highest Resolution Seamless Display Has 60M Pixels

Conditioned by Bradbury's remarks about parlor walls - those big screen TV predictions of his - and how they are going to be the end of Western Civ, I feel bad whenever I contemplate the vast Wall o' Flat Screen TVs at my local Best Buy. Well, not really bad, because I want one.

And now, it looks like you could have something pretty close that's not just a set of juxtaposed smaller TVs. At the IdeaFestival held recently in Louisville, Kentucky, computer engineers Christopher Jaynes and Stephen Webb created a display technology (sold under the Mersive name) that lets the display itself align itself by viewing itself. Try that again:


(Mersive arbitrarily large displays)

Mersive’s calibration and runtime software, Sol™, is at the heart of the solution. The Mersive Sol Server automatically calibrates multi-projector arrays into a seamless display through geometry warping, intensity blending and color correction in quickly and scalably with no "user-in-the-loop.” Sol makes configuring a display a simple two-step process.

First, Sol uses a video camera to view the display. Sol commands the display controllers to send visual information to individual projectors which the Sol Server collects using the camera. By collecting information from the display, the Sol Server can determine the layout of the projectors, where the projectors are overall, the shape of the display and how best to blend all the information together seamlessly. By using a high-resolution digital-camera, the Sol Server can compute geometric, intensity, and color-blending parameters that are far more accurate than is possible by a human operator. Furthermore, the process takes minutes, not days of manual alignment.

Their goal is to create compelling high-resolution displays using ordinary equipment, plus their Mersive Sol Server.

"Think about tying together eight projectors in your basement to have a beautiful home theater," Jaynes said. "Or two gamers could come together and project their games' content together on a surface. When somebody else gets a projector for Christmas, they could do it too."
