The polarizing device includes: a base substrate, a metal wire grid, and an anti-reflection layer, in which the metal wire grid is arranged on the base substrate, the anti-reflection layer is arranged on the surface of the metal wire grid away from the base substrate, and the anti-reflection layer is a carbon film layer.

The present disclosure relates to an assembly for an electronic device comprising: a display screen; an optical light emitter adapted to emit an Infrared or near Infrared light beam through the display screen; the optical light emitter and the display screen being of the type that, when an unpolarized light beam from the optical light emitter passes through a region of the display screen, a white spot of a first intensity is formed in the region; a light polarizer positioned between the optical light emitter and the display screen, the light polarizer being orientated such that a white spot of a second intensity, lower than the first intensity, is formed when the light beam, from the optical light emitter and polarized by the light polarizer, passes through the region of the display screen.

Provided is an optical element in which a metal layer with good adhesion is formed on a resin substrate. An optical element includes: a resin substrate; and a stacked body including a metal oxide layer provided on the resin substrate and a metal layer provided on the metal oxide layer. The metal oxide layer is a lanthanum oxide of ternary or more.

Optical devices with different regions or pixels can form an image. An opaque-region 14 can be used to separate different pixels. Sometimes the optical device needs to be flexible, for elongation or stretching onto a curved surface. But, the opaque-region 14 can be damaged as it is stretched. A flexible optical device can include a modified opaque-region 14 for improved flexibility. The opaque-region 14 can include a thin-film 12 with multiple cavities 13, multiple zones 63, or both. Each zone 63 can have a shape optimized to both block incoming light and for flexibility. Each zone 63 can be encircled and separated from adjacent zones 63 by a groove 62. The cavities 13 and the separate zones 63 can allow the opaque-region 14 to bend or stretch without cracking or delamination of the thin-film 12.

A wire grid polarizer (WGP) can have a conformal-coating to protect the WGP from at least one of the following: corrosion, dust, and damage due to tensile forces in a liquid on the WGP.

The photodiode is coupled to generate charge in response to incident light directed through a first side of the semiconductor layer. The polarizer includes a first metal grid formed with a first metal layer and a second metal grid formed with a third metal layer. The second metal grid is stacked with the first metal grid such that the first and second metal grids are disposed above and aligned with the photodiode. The photodiode is optically coupled to receive incident light through the first and second metal grids of the polarizer and through the first side of the semiconductor layer.

Wire grid polarizer and manufacturing method thereof are provided, the wire grid polarizer includes: substrate; first wire grid formed on substrate, including first wire grid reflection strips arranged parallel to each other and at equal intervals; second wire grid formed at a side of first wire grid away from substrate, including second wire grid reflection strips arranged in parallel to each other and at equal intervals; second wire grid reflection strips are in one-to-one correspondence with first wire grid reflection strips; orthographic projections of second wire grid reflection strip onto substrate falls within orthographic projections of corresponding first wire grid reflection strip onto substrate; wire width of second wire grid reflection strip is less than that of first wire grid reflection strip; and wire spacing of second wire grid reflection strip is greater than that of the first wire grid reflection strip.

The present disclosure generally relates to methods and systems for manufacturing wire grid polarizers (WGP) using Markle-Dyson exposure systems and dual tone development (DTD) frequency doubling. In one embodiment, the method includes depositing a photoresist layer over an aluminum-coated display substrate, patterning the photoresist layer by dual tone development using a Markle-Dyson system to form a photoresist pattern, and transferring the photoresist pattern into the aluminum-coated display substrate to manufacture a WGP having finer pitch, for example less than or equal to about 100 nm, and increased frequency.

An optical element is provided. The optical element includes a substrate; a plurality of metal grids formed on the substrate; an oxide layer formed on the substrate between the plurality of metal grids; and a plurality of organic layers formed on the plurality of metal grids, wherein the width of the organic layer is greater than the width of the metal grid, and there is at least one gap between the organic layer and the oxide layer.

A see-through display including a polarized reflective pinhole mirror display. The pinhole mirror display includes a plurality of tiny switchable polarized mirrors. The respective polarized mirrors individually reflect impinging light from an illuminator, and guide the respective portion of light into a pupil of an eye. A reflective optically powered surface reflects light from the illuminator. Each mirror has a first polarization and reflects a portion of light and produces a picture element (pixel) that forms a virtual image seen by the eye of the user. A user may view the reflected virtual image having the first polarization from the illuminator, as well as the image from the real world via a rear substrate that has a second polarization. Although the mirrors are very small, human eyes can still detect the mirrors if they are not polarized. The mirrors and other components are polarized so that the eye can see the real world filtered with the second polarization, but not the mirrors having a different first polarization.
