Abstract
A method of making a polarizer can include applying a liquid with solid inorganic nanoparticles dispersed throughout a continuous phase, then forming this into a different phase including a solid, interconnecting network of the inorganic nanoparticles. This method can improve manufacturability and reducing manufacturing cost. This method can be used to provide an antireflective coating, to provide a protective coating on polarization structures, to provide thin films for optical properties, or to form the polarization structures themselves.
Claims20
A method of making a polarizer, the method comprising:
- providing (a) a substrate that is transparent and has a first side and a second side opposite of the first side, and (b) a polarization device located on the first side of the substrate, the polarization device including objects arranged in a pattern for polarization of light;
- applying an uncured backside layer to the second side of the substrate, the uncured backside layer being a liquid with solid inorganic nanoparticles dispersed throughout a continuous phase;
- and
- curing the uncured backside layer to form a cured backside layer, the cured backside layer including a solid, interconnecting network of the inorganic nanoparticles.
A method of making a polarizer, the method comprising:
- providing (a) a substrate that is transparent and has a first side and a second side opposite of the first side, and (b) a polarization device located on the first side of the substrate, the polarization device including objects arranged in a pattern for polarization of light;
- applying an uncured backside layer to the second side of the substrate, the uncured backside layer being a colloidal suspension including a dispersed phase and a continuous phase;
- imprinting a pattern of structures in the uncured backside layer, the structures sized and shaped to reduce reflection of incident light, to increase heat transfer away from the polarizer, or both;
- and
- curing the uncured backside layer by removing the continuous phase to form a solid, defining a cured backside layer.
A method of making a polarizer, the method comprising:
- providing:
- a substrate that is transparent and has a first side and a second side opposite of the first side;
- and a polarization device located on the first side of the substrate, the polarization device including objects arranged in a pattern for polarization of light;
- applying an uncured backside layer to the second side of the substrate, the uncured backside layer being a solution including molecules in a solvent, the solvent including water and an organic liquid, the molecules including metal atoms bonded to reactive groups, where each reactive-group is independently —Cl, —OR1, —OCOR1, or —N(R1)2, and R1 is an alkyl group;
- and
- reacting the molecules to form a solid of the metal atoms interconnected with each other, defining a cured backside layer.
