Display Video Wall Overview
What is a Rear Projection Display Cube?
A rear projection display cube is a projection device that is designed to interlock with other cubes and create a video wall. A rear projection display cube is unique from other front and rear projection devices for three reasons:
- The ability to project its image to the edge of the screen, resulting in a mullion of 1mm or less between two adjacent screens.
- The ability to operate 24 hours a day 7 days a week without any degradation in performance or operation.
- The ability to match color and brightness between adjacent screens so that the overall display wall looks like one continuous image.
How a Rear Projection Display Cube works
A rear projection display video wall cube consists of four key components: cube enclosure, mirror, projection screen, and projection engine.
Cube Enclosure – The cube enclosure creates an environment absent of ambient light. This enables the projection cube to be placed into situations that may be exposed to high ambient lighting which can reduce the brightness of the screen.
Mirror – The mirror bends the direction of the light from the projection engine to the projection screen. This enables the rear projection display cube to remain very compact. Typical rear projection cubes range in depth between 24” 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 rear projection cube will be.
Projection Engine – 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 rear projection cube will be. There are different types of screens available depending on whether your emphasis is on the horizontal or vertical viewing angles. Ambient lighting in a room, and the detail with which the contents has to show will also affect your choice of the type of screen used.
Combining Cubes into a Video Wall
By combining one or more cubes you are able to create a display wall. Each display cube is designed to interlock together, allowing you to create a display of virtually any size. By adding more projection display cubes together you gain the advantage of additive resolution.
Interlocking more projection display cubes together allows:
- Larger display surface
- Higher resolution to display more content
- Multiple work zones for clustered workgroups
