Method and apparatus for managing optical non-uniformities in seaming processes

A method for managing optical non-uniformities, comprising:

• maintaining a substantially constant average optical loss across an interface by printing patterns over a region in which the optical loss occurs, wherein the patterns optically absorb at least some light.

A method for forming a seam that substantially reduces the appearance of optical non-uniformities at the seam, comprising:

• maintaining approximately constant average optical loss in the vicinity of the seam by substantially controlling reflectivity in the vicinity of the seam, wherein substantially controlling reflectivity in the vicinity of the seam further comprises employing a backer treated to minimize optical reflectivity over a range of angles.

A front projection screen with a projection surface, the front projection screen, comprising:

• a first portion of a first substrate and a first portion of a second substrate, wherein the first portion of the first substrate and the first portion of the second substrate are perforated with holes;
• and
• a backer operable to join the first portion of the first substrate and the first portion of the second substrate, wherein the first portion of the first substrate forms a seam with the first portion of the second substrate, further wherein the backer is textured such that the surface of the first side of the backer performs substantially similar as a diffuser.
