A projection screen apparatus and method of making the same. The apparatus has a perimeter frame and a projection screen where the perimeter frame includes an upper frame member, a lower frame member, a left frame member and a right frame member, where at least two of the frame members have a groove or track. The projection screen has fastening edges on at least two opposite sides for fastening the projection screen to the perimeter frame by inserting the fastening edge in the groove or track of a frame member. An auxiliary element is inserted in the groove or track next to a fastening edge, to prevent the fastening edge from exiting the groove.

Tensioned projection screen

A curved projection screen having a one-piece seamless substrate having a three-dimensional curvature. The screen is arranged for being bent to a certain degree around one of its axes so that the smallest deformation of the screen is elastic, where the edge of the screen has been shaped so that its deformation during the above mentioned degree of bending is also elastic.

Curved projection screen

The present invention relates to projection systems, more particularly to a method for visualising test pattern grids in such a projection system. An array of adjustable, directed light sources is described, which is to be used as a test pattern generator for alignment of at least one projector. Each light source is fixed onto a surface from which it is movable with two degrees of freedom, preferably by putting the surface in plastic deformation. This can preferably be done with help of few tooling aids, and by using one hand only.
