Entry level 50" single lamp video wall system integrating DLP™ technology with XGA resolution

Barco 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 optical dimmer guarantees equal brightness and contrast across the video wall and keeps the performance of the display constant over time.

Luminance guidelines

• All luminance values are given for on-axis viewing. The 50% luminance value will be present when viewing under the half gain angles (see ‘screens table’)
• 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

• 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 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 video wall,
• equal luminance of the video wall across time,
• ergonomic dimming of full video wall for day and night operation
