Methods to eliminate/reduce the crosstalk artifacts of the retro-reflective auto-stereoscopic 3D display

A screen system, comprising:

• a plurality of projectors, each configured to project a unique image;
• a screen having a front surface and a back surface, with the front surface facing said plurality of projectors;
• a viewing region defined in an area substantially along, a line normal from said projectors to said screen;
• wherein said screen is divided into a left plane and a right plane, said left and right planes being angled at a junction joining said left plane to said right plane, said angle being sufficient for directing a mirror reflection on said left and right planes, of the unique images from said projectors, away from said viewing region;
• wherein said left and right planes are angled toward said projectors so that said junction is the part of the screen farthest from the projectors, the left and right planes forming a second target angle, φ, with reference to a first reference line perpendicular to a second reference line normal to said projectors traversing said junction, said second target angle being not less than
