Which control room video wall technology consumes least energy?Johan BekaertBarco Newsroom

The results pretty much speak for themselves. RPC consumes the least energy. The RGB laser sources we used in the test provide a high level of illumination for a minimal amount of power. LCD follows rather closely. LED, with its many tiny lighting sources, is the most gluttonous technology today. Note however that the energy-consumption of LED has dropped significantly over the years, and the industry (including Barco) is working hard to get this further down. Innovation can be expected on that front!

It is interesting to see on the graph that for RPC and LCD video walls, the power consumption remains the same whatever the content. So, a test with full white content and typical SCADA-image consumes exactly the same amount of energy. For LED, this is very different.
