Visual ergonomics in the control room


Control room operators have a visually demanding job and are often working long shifts monitoring video wall content

Fortunately, visual ergonomics is playing an increasingly vital role in control room design.

Truly seamless viewing

The seams or mechanical gaps between multiple screens or panels of a video wall can be a major hindrance. Unlike with LCD and rear-projection, directview LED video walls have no screen gaps. However, it can still be difficult to perfectly align the different LED panels: the ground surface is never 100% flat and walls are never completely even.

With the smart engineering system of TruePix, adjacent modules are automatically aligned without interrupting the diode pattern. TruePix also relies on the force of gravity and the principle of communicating vessels to absorb imperfect floor conditions or uneven walls. As a result, the LED wall is perfectly level and completely frictionless.

High brightness and dimming

Direct-view LED provides plenty of brightness, with great contrast and increased viewing angles. But LED video walls can also be dimmed, which is critical for night-time operation or windowless control rooms. However, dimming should not result in reduced sharpness, legibility or color changes.

Barco’s TruePix video walls and Infinipix Gen2 image processing platform incorporate patented driver algorithms which will preserve all true details of the image, even when the display system is dimmed to extreme values. SteadyView technology eliminates patterns on the videowall that may cause eye fatigue. This is especially important with dimmed video walls and when staff needs to monitor content for multiple hours on end.

Reliable colours

Control room video walls need to show their colours with utmost accuracy, so they look the way they are meant to be. The challenge is to maintain a constant brightness and calibrated colors over the entire video wall over time. A colour mismatch between different display modules may result in a checkerboard pattern of different colors and brightness levels.

Barco’s image processing solution Infinipix Gen2 makes sure the LED display shows the same colour tone, colour bit depth, grayscale and level of detail while operating in dimmed mode and at full brightness.

Barco’s unique Smart Calibration unlocks the support of wide color gamuts (DCIP3 and REC2020), while batch compatibility ensures uniform colours at all time.
