    Tensor Displays

Description:


    We introduce tensor displays: a family of light field displays comprising all stacked display architectures employing lightattenuating layers illuminated by uniform or directional backlighting (i.e., any low-resolution light field emitter). Tensor displays include the capability to time-multiplex content across frames on each of the layers to improve image quality. We show that the light field emitted by an N-layer, M-frame tensor display can be represented by an Nth-order, rank-M tensor. In a related technical paper submission, we use this representation to introduce a unified optimization framework, based on nonnegative tensor factorization (NTF), encompassing all tensor display architectures (see supplementary supporting document). In this emerging technologies demonstration, we show both static, printed tensor displays, and dynamic LCD-based systems, providing wide field-of-view, bright, high-resolution, glasses-free 3D display.
