Abstract
Systems and methods for convergent 3D displays. In one embodiment, the 3D display has a display screen that includes a convergent reflector and a horizontally narrow angle diffuser. The convergent reflector focuses 2D images projected on the diffuser from an array of 2D image projectors to form viewpoints in an eyebox where one viewpoint corresponds to one projector. At a particular viewpoint, the viewer's eye sees a full-screen field of view from a corresponding projector in the array. The narrow angle diffuser diffuses incident rays projected from the 2D image projectors into narrow angular slices so that the views in the eyebox are continuously blended together. The system and methods provide advantages in that only a few projectors are required in the array to provide the viewer with a full-screen field of view and a sufficiently large eyebox for comfortable viewing.
