A wire grid polarizer (WGP) can include a flexible substrate. The flexible substrate might be desirable for WGP flexibility or to aid in further processing of the WGP. Wires of the WGP can include flexible ribs to minimize or avoid defects such as cracks in the WGP. An etch stop layer in the wires can allow formation of the flexible ribs without delamination of a reflective portion of the wires. The WGP embodiments herein can have improved flexibility, stretchablility, compressibility, or combinations thereof with reduced cracking, collapse, and delamination of wires or ribs.

Flexible wire grid polarizer

A wire grid polarizer (WGP) can include a flexible substrate. The flexible substrate might be desirable for WGP flexibility or to aid in further processing of the WGP. Wires of the WGP can include flexible ribs to minimize or avoid defects such as cracks in the WGP. An etch stop layer in the wires can allow formation of the flexible ribs without delamination of a reflective portion of the wires. The WGP embodiments herein can have improved flexibility, stretchability, compressibility, or combinations thereof with reduced cracking, collapse, and delamination of wires or ribs.

A method for making a wire grid polarizer (WGP) can provide WGPs with high temperature resistance, robust wires, oxidation resistance, and corrosion protection. In one embodiment, the method can comprise: (a) providing an array of wires on a bottom protection layer; (b) applying a top protection layer on the wires, spanning channels between wires; then (c) applying an upper barrier-layer on the top protection layer and into the channels through permeable junctions in the top protection layer. In a variation of this embodiment, the method can further comprise applying a lower barrier-layer before applying the top protection layer. In another variation, the bottom protection layer and the top protection layer can include aluminum oxide. In another embodiment, the method can comprise applying on the WGP an amino phosphonate then a hydrophobic chemical.

Durable, high performance wire grid polarizer having barrier layer

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 conformal-coating can include a silane conformal-coating with chemical formula (1), chemical formula (2), or combinations thereof: A method of applying a conformal-coating over a WGP can include exposing the WGP to Si(R)(R)(R). In the above WGP and method, X can be a bond to the ribs; each Rcan be a hydrophobic group; each R, if any, can be any chemical element or group; d can be 1, 2, or 3, e can be 1, 2, or 3, g can be 0, 1, or 2, and d+e+g=4; Rcan be a silane-reactive-group; and each Rcan be an alkyl group, an aryl group, or combinations thereof.

Wire grid polarizer with protective coating

A wire grid polarizer (WGP) can include a heat-dissipation layer. The heat-dissipation layer can enable the WGP to be able to endure high temperatures. The heat-dissipation layer can be located (a) over an array of wires and farther from a transparent substrate than the array of wires; or (b) between the array of wires and the transparent substrate. The heat-dissipation layer can be a continuous layer. The heat-dissipation layer can have a high electrical resistivity and a high coefficient of thermal conductivity.

A wire grid polarizer (WGP) can have a conformal-coating to protect the WGP from oxidation and/or corrosion. The conformal-coating can include a barrier layer with at least one: of aluminum oxide, silicon oxide, silicon nitride, silicon oxynitride, silicon carbide, hafnium oxide, and zirconium oxide. A method of making a WGP can include applying the barrier layer over ribs of a WGP by vapor deposition.
