A projection technology in a data wall consists of a rear projection device that is designed to interlock with other cubes and create a data wall. A projection cube has advantages from other more common rear projection devices :
It has the facility to project its image to the edge of the screen seamless and approx 1mm or less between two adjacent cubes.
Without decreasing the efficiency and performance, the cube can project and operate 24 hours a day 7 days a week for critical applications.
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 display wall consists of four key components: cabinet, mirror, projection screen, projection engine.
Cabinet – The cabinet 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.
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, 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 high resolution display 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 thereby increase in performance and efficiency.
With the aid of interlocking one cube to other we are able to provide a larger display area with much higher resolution to provide clarity to the display content. Even it helps to monitor multiple work zones or enlarge a single work zone from the clustered work groups.
a) Screen Technology
Screens distribute light from the optical engines towards the observer
The quality of the screen defines the brightness distribution and the viewing angles, avoiding, eg hotspots.
High quality screens consists of different optical layers, usually a Fresnel layer and a distribution layer.
b) Lamp Technology
UHP (Ultra High Pressure) Lamps
100W to 120W power consumption
Best Brightness/Power Consumption Ratio
Low brightness drop during operation time
Average operation time 6000 to 10000 hours per lamp
c) Optical Engine- Features:
Modular design for short MTTR
Optical engine: Easily removable color wheel and electronics board (without removing engine)
Easy filter replacement
6 axis geometry adjustment for a perfect geometry
