Selecting The Appropriate Brightness For A Control Room Display
Operator comfort, not impact, is the goal.
The demands on a control room display wall are high. It must allow multiple operators to see crucial information, providing a common operating picture they can use to work collaboratively in critical situations.
For that reason, the optimal brightness of a control room display wall is a lot different than the brightness of the video walls you may see in an airport, retail mall or entertainment venue. There, impact is the key, as the displays are meant to capture attention and hold it for short periods of time. Brightness and contrast are at a premium.
