Barco Control Rooms designed a projection module based on an innovative modular approach. The concept of having a separate projection unit and illumination unit is unique and results in an easy to maintain projection cube with superior picture quality. The built in lamp redundancy reduces operational costs and ensures a permanent image. The optical dimmer guarantees equal brightness and contrast across the display wall and keeps the performance of the display constant over time.
Luminance guidelines
• All luminance values are always given for on-axis viewing. The 50% luminance value will be present when viewing under the half gain angles
• All luminance values are measured at 6500 K color temperature, normally applied in control rooms for natural lighting conditions
• Luminance at other color temperatures can be communicated upon request

High-precision screen
• provides high-contrast, even in bright ambient light
• type of screen is selected based on overall environmental conditions and operational requirements
• excellent visibility under any viewing angle
• patented stitch solution provides seamless solution
• screen modules with easy mounting and narrow screen gap
• all screens are double element screens to avoid hotspotting on each display
Optical dimming with dynamic feedback
A patent pending optical dimming system in combination with a dynamic feedback control loop results in a uniform image across the wall and maintains the brightness over time. This feature allows:
• independent brightness control of each module without loss of contrast or color depth
• equal brightness, contrast and color depth across the display wall
• equal luminance of the display wall across time
• ergonomic dimming of full display wall for day and night operation

Redundancy concept
• dual lamp: 100% availability of your display wall
• 3 modes:
Hot standby: 2nd lamp is on, i.e. the switching time in case of lamp failure of the master lamp is virtually zero
Cold standby: 2nd lamp is switched off during operation, i.e. it will only be activated when master lamp failure is detected – switching takes around 30 seconds
Auto Switch mode: ensuring controlled, balanced aging of the lamps
• no image loss in hot stand-by
• lamp change without direct operator intervention
• lamp changes can be planned
• lower operational costs
• failed lamp can be replaced while other lamp generates image
• standard Dual DVI-D allows connection of two simultaneous sources or controllers for full redundancy upon failure of one source or controller
