There's no indication as to how the display works. Perhaps the docking station itself has a display that's powered by the laptop, though it seems silly to have two displays. It could be that the laptop in question is actually a tablet that docks with its own display facing the user.
The patent also mentions liquid cooling and a "telephonic handset." It's all interesting, but who knows if any of this will come to fruition. Perhaps we'll see next week.
