Figure 1: Wide field of view glasses-free 3D display using tensor displays. (Left) We introduce a new family of light field displays, dubbed tensor displays, comprised of stacks of light-attenuating layers (e.g., multilayer LCDs). Rapid temporal modulation of the layers is exploited, in concert with directional backlighting, to allow large separations between viewers. (Right) From left to right: target light field view, photograph of three-layer LCD with uniform backlighting, and photograph of single LCD with directional backlighting. Layers are shown to the right of each photograph. The upper and lower rows depict perspectives seen to the left and to the right of the display, respectively. AbstractWe introduce tensor displays: a family of compressive light field displays comprising all architectures employing a stack of timemultiplexed, light-attenuating layers illuminated by uniform or directional backlighting (i.e., any low-resolution light field emitter). We show that the light field emitted by an N -layer, M -frame tensor display can be represented by an N th -order, rank-M tensor. Using this representation we introduce a unified optimization framework, based on nonnegative tensor factorization (NTF), encompassing all tensor display architectures. This framework is the first to allow joint multilayer, multiframe light field decompositions, significantly reducing artifacts observed with prior multilayer-only and multiframe-only decompositions; it is also the first optimization method for designs combining multiple layers with directional backlighting. We verify the benefits and limitations of tensor displays by constructing a prototype using modified LCD panels and a custom integral imaging backlight. Our efficient, GPU-based NTF implementation enables interactive applications. Through simulations and experiments we show that tensor displays reveal practical architectures with greater depths of field, wider fields of view, and thinner form factors, compared to prior automultiscopic displays.

In this paper, we review the device structures and present the simulation results of four single-domain LCDs with a quasi-collimated backlight and a free-form optics-engineered diffuser. Such a non-emissive LCD exhibits similar luminance distribution to an emissive OLED, while keeping high transmittance, high contrast ratio over a large (80 ) viewing cone, with low ambient reflection, indistinguishable color shift, and negligible off-axis grayscale distortion.Index Terms-Fringe field switching, in-plane switching, liquid crystal display (LCD), OLED-like luminance distribution, single domain.

The ability of the Lucius prism array to directionally allocate the incident light intensity suggests its use in various optical devices [18][19][20][21][22][23][24][25][26] , such as dual-view or autostereoscopic 3D display [27][28][29][30][31] . To perceive a 3D image, human eyes must see different views (binocular disparity), allowing for the sensation of depth known as stereopsis after complicated processing in the brain 29 .…”

Directional and asymmetric properties are attractive features in nature that have proven useful for directional wetting, directional flow of liquids and artificial dry adhesion. Here we demonstrate that an optically asymmetric structure can be exploited to guide light with directionality. The Lucius prism array presented here has two distinct properties: the directional transmission of light and the disproportionation of light intensity. These allow the illumination of objects only in desired directions. set up as an array, the Lucius prism can function as an autostereoscopic three-dimensional display.
