Abstract
A wire grid polarizer with multiple functionality sections. Separate and discrete sections can include a difference in pitch p, a difference in wire width w, a difference in wire height h, a difference in wire material, a difference in coating on top of the wires, a difference in thin film between the wires and the substrate, a difference in substrate between the wires, a difference in number of layers of separate wires, and/or a difference in wire cross-sectional shape.
Claims20
A wire grid polarizer, comprising:
- a) a substrate;
- b) at least two separate and discrete sections of different wire grids disposed over and attached to the substrate;
- c) the wire grids comprising substantially parallel elongated wires disposed over the substrate;
- and
- d) the different wire grids or the at least two sections having a different wire grid structure with respect to one another, wherein the different structure is:
- i) a difference in wire material;
- ii) a difference in coating on top of the wires;
- iii) a difference in thin film between the wires and the substrate;
- iv) a difference in substrate between the wires;
- v) a difference in number of layers of separate wires;
- or
- vii) combinations thereof.
