I don't know, but I'd imagine there are rows of transducers of some sort energising/moving the screen surface, working rather like an isodynamic speaker. If so these could be arranged in 'left' and 'right' configurations. I wonder if an oscillating screen surface would produce any detectable doppler effects in the viewed image. Light wavelengths are probably too small I expect.
It is impossible for anything digital to sound analogue, because it isn't analogue!
