Three-dimensional display and method of installing a three-dimensional display

A method of assembling three-dimensional display apparatus, comprising the steps of:

• providing a support unit comprising a projector mounting and a screen mounting surface with a first aperture therethrough;
• providing a screen unit, the screen unit comprising a diaphragm and an inflatable screen affixed thereto, the diaphragm defining a second aperture in communication with the interior of the inflatable screen;
• bringing the screen mounting surface and the diaphragm into contact so as to align the first aperture with the second aperture;
• and
• securing the support unit to the screen unit to thereby create a seal between the support surface and the diaphragm around the first and second apertures, wherein the seal is sufficiently gas tight to enable inflation of the screen.
