3D glasses having an RFID tag (embedded in one or more temples) are rented to theater or other venue operators. The glasses are shipped to a venue for distribution to patrons and collected from patrons in the trays. Inventory and other measures are implemented by RFID scanning while the glasses are in the trays (e.g., upon delivery to a theater, on collection from the theater, upon inspection at the 3D rental company, etc). Data gathered from RFID scanning and inspections allows the rental company to properly allocate rental costs to various venues based on shrinkage which includes, for example, extraordinary wear of the glasses, breakage or theft, which is attributable and traceable to the specific venues. The theater or venue may also independently scan the trays upon delivery and pick-up to maintain their own records. The invention includes 3D glasses with RFID, a washing rack, and rental systems.

The system may comprise an image-generating source to provide one or more frames of image data in a time-sequential manner, a light modulator configured to transmit light associated with the one or more frames of image data, a substrate to direct image information to a user's eye, wherein the substrate houses a plurality of reflectors, a first reflector of the plurality of reflectors to reflect transmitted light associated with a first frame of image data at a first angle to the user's eye, and a second reflector to reflect transmitted light associated with a second frame of the image data at a second angle to the user's eye.

A display apparatus includes a screen formed in an arcuate shape centering on a center axis and a projection device configured to project, along projecting directions orthogonal to the center axis and different from one another, images corresponding to the projecting directions on the inner circumferential surface or the outer circumferential surface of the screen. The screen includes a retroreflective layer having a reflection surface directed to the projection device and a diffusion layer arranged on the projection device side with respect to the retroreflective layer and configured to diffuse, when transmitting light made incident from the retroreflective layer, the light wider in a first direction along the center axis than in a second direction, which is a circumferential direction centering on the center axis.

An optical element is configured by connecting a plurality of tiles each constituted by a plurality of reflective optical elements, and is formed in a shape having a plane surface. The tiles configuring the optical element are formed such that outer shapes on the plane surface of the tiles have at least two different triangular shapes, while an end surface of each tile is provided with a light shielding part.

An input-coupler of an optical waveguide couples light corresponding to the image and having a corresponding FOV into the optical waveguide, and the input-coupler splits the FOV of the image coupled into the optical waveguide into first and second portions by diffracting a portion of the light corresponding to the image in a first direction toward a first intermediate-component, and diffracting a portion of the light corresponding to the image in a second direction toward a second intermediate-component. An output-coupler of the waveguide combines the light corresponding to the first and second portions of the FOV, and couples the light corresponding to the combined first and second portions of the FOV out of the optical waveguide so that the light corresponding to the image and the combined first and second portions of the FOV is output from the optical waveguide. The intermediate-components and the output-coupler also provide for pupil expansion.

A lenticular lens film includes a substrate, a plurality of lenticular lenses, and a plurality of wire grating polarizers. The substrate includes a front surface and a back surface. Each of curved surfaces of the lenticular lenses are arranged on the front surface of the substrate in parallel, and the curved surfaces of the lenticular lenses faces away from the front surface of the substrate. The wire grating polarizer includes a dielectric layer formed on the back surface of the substrate, and a metallic layer having a plurality of metal strips arranged on the dielectric layer, the metal strips are parallel to each other and are spaced apart from each other. In addition, the present disclosure also relates to a 3D display device.
