Visualization specialist Barco announced that its new LED-lit rear-projection video walls are now available for sales. The OL series of video walls presents significant quality improvements over the current state of the art in LED projection.

Barco's OL rear projectors come with Sense6, a unique sensor technology which co-ordinates across multiple rear-projection modules to provide brightness and color stability over time and across the entire video wall screen. An integrated spectrometer continuously measures brightness and color characteristics of the full visual spectrum. Sense6's algorithms monitor the outputs of these spectrometers in real time and then dynamically and automatically adjust all the projectors of the video wall to generate an image that is most suited for viewing by the human eye. Unlike factory calibrated systems, the OL continuously measures and adjusts color and brightness in real time and therefore requires no maintenance or manual adjustments.

Barco's LED-lit video walls have an advanced heat management system based on state-of-the-art liquid cooling to efficiently counteract the effects of high temperatures on the LED light sources. In comparison to heat pipe systems, Barco's liquid system can provide an additional ten degrees of temperature decrease on the LED light source. This effectively doubles the lifetime of the LED light source and reduces noise substantially.
