Abstract
Complementary near-field and far-field light field displays (LFDs) are provided. A distributed LFD system is disclosed in which the light field is cooperatively displayed by a direct view LFD and a near-eye LFD. The two display components of the system work together synchronously to display a high-fidelity 3D experience to one or multiple viewers.
