Abstract: A projection screen apparatus comprises a support blank of a lightweight, rigid material defining a front face surface having a smooth concave curvature in two orthogonal directions. The front face surface terminates at a mounting rim skirting the front face surface peripherally. A projection screen is fixed to the front face surface of the support blank thereby assuming its doubly concave curvature. A box-like fixture supports the blank while suction is drawn between the front face of the blank and the screen material so as to draw the screen material into intimate contact with the surface of the blank in order to bond the screen to the blank.
