| 摘要 |
A projection screen includes a transparent substrate having a first side and a second side, a first optically clear adhesive ("OCA") layer disposed across the first side of the transparent substrate, a first two-dimensional ("2D") matrix of clear beads partially embedded into the first OCA layer, and a dark layer disposed across the first OCA layer filling in exposed gaps between the clear beads to block and absorb light incident upon the exposed gaps between the clear beads. The clear beads form optical paths through the dark layer. |
