I dont think those are rear projection displays. I think the numeric displays are what we called nixie tubes.
I can see why you might think that; the slight misalignment of the digits does look like the depth effect seen with Nixie tubes. I hadn't noticed that at first.
I still think they're rear-projection units, based on the quality of the images and their color. The misalignment could be due to misalignment within the projection unit itself. Still, you could be right.
