A projection cube is a rear projection device that is designed to interlock with other cubes and create a video wall. A projection cube is unique from other more common rear projection devices for three reasons:

1. The ability to project its image to the edge of the screen, resulting in a mullion of 1mm or less between two adjacent screens.
2. The ability to operate 24 hours a day 7 days a week without any degradation in performance or operation.
3. The ability to match color and brightness between adjacent screens so that the overall display wall looks like one continuous image.

How a Projection Cube works

A projection cube consists of four key components: cube enclosure, mirror, projection screen, projection engine.

Cube Enclosure – The cube enclosure creates an environment absent of ambient light, which can reduce the brightness of the screen. This enables the projection cube to be placed into situations that may be exposed to high ambient lighting. Mirror – The mirror bends the direction of the light from the projection engine to the projection screen. This enables the projection cube to remain very compact. Typical projection cubes range in depth between 21” and 38”. Projection Screen – The projection screen is the surface on which the image is projected. The quality and selection of this component is vital as it will determine how satisfactory the viewing angles and brightness of the projection cube will be. Projection Engine – The projection engine relates to image generation. This component actually projects the image from a computer or video source onto the screen. It is called a projection engine, as opposed to projector, because the optical component is separated from the electronics module and power supply. This allows for quick replacement in the event of a component failure.

Combining Cubes into a Video Wall

By combining one or more cubes you are able to create a video wall. Each cube is designed to interlock together, allowing you to create a display of virtually any size. By adding more projection cubes together you gain the advantage of additive resolution.

Interlocking more projection cubes together allows:

• Larger display surface
• Higher resolution to display more content
• Multiple work zones for clustered workgroups
