Ultra Hi Resolution 3D Tiled Display

Designers: Client Staff / BBI

This is a 3D-ultra high resolution display. If you have to ask, you probably can’t afford it. It serves as the output display for the world’s largest supercomputer, IBM’s Purple, running at 110 teraflops.

The image itself is 20 ft wide by 8 ft tall with 5000 x 2000 pixels of 3D resolution. This is significantly more than a large video computer display that would typically be 640 x 480 or 1280 x 768.

For 3D operation, the audience wears glasses with LCD shutters. The glasses are synchronized using an infrared signal which opens one eye at a time to produce the 3D effect.

The main image is composed of 8 images tiled as 2 rows of 4. We are using 8 Christie V/R-Simulation grade projectors with 2 axis lens shifts to carefully align the edges. The projectors are mounted on 4 axis mounts so they are level and true. In addition, there are very thin aluminum adjustable vanes between each cell. These are mounted to the rear of the glass screen to prevent over scan from once cell spilling into the adjacent cell.

Alas, we have no picture of the output image as this is in a classified facility. It looked great on a test image though.
