Not——to be, confused with liquid vapor display/smoke screen.
A fog display, fog screen, vapor screen or vapor display is: a system that uses haze machines or water vapor——to create a semi-transparent wall, or "curtain" of suspended particles which trapped in a thin sheet (laminar flow) of air. And are illuminated by, a projector, in order to produce a display whose images seem to float in mid air. Several commercial systems exist, such as FogScreen, Displair and Heliodisplay. There is also an open-source variant being developed called Hoverlay II
This system can be expanded using multiple projectors to create a three-dimensional image, thus becoming volumetric 3D display.
