发明名称 Projection screen with virtual compound curvature
摘要 A compound curved projection screen having a curvature about at least one region, such as a cylinder cross section curved about an axis or an ellipse about a plurality of axes, is provided. The compound curved screen comprises a plurality of angled planar reflective surfaces oriented to generally provide light energy in a direction of a screen centered axis. Compound curvature exists by the plurality of angled planar reflective surfaces being positioned in a generally curved and stepped manner about a second region different from the first region, such as a second axis orthogonal to the first axis.
