I doubt it actually has a holographic display; I assume that processing power of those glasses isn't enough and current display don't have high enough resolution yet. But then again the following description could be a holographic display (or it could be a description of antireflective coating -- those dumbed down explanations are sometimes worse than useless) > To create Project HoloLens’ images, light particles bounce around millions of times in the so-called light engine of the device. Then the photons enter the goggles’ two lenses, where they ricochet between layers of blue, green and red glass before they reach the back of your eye. “When you get the light to be at the exact angle,” Kipman tells me, “that’s where all the magic comes in.”
