Abstract
A sheet including a reflector having a first surface, a second surface opposite the first surface, and a third surface; a first selective light modulator layer external to of the first surface of the reflector; and a second selective light modulator layer external to the second surface of the reflector; wherein the third surface of the reflector is open is disclosed. A method of making a sheet is also disclosed.
Claims17
A method for manufacturing a sheet comprising:
- depositing on a substrate a first selective light modulator layer;
- depositing on the first selective light modulator layer at least one reflector;
- depositing on the at least one reflector a second selective light modulator layer, the sheet comprising the first selective light modulator layer, the at least one reflector and the second selective light modulator layer;
- and
- releasing the substrate from the sheet,
- wherein at least one layer chosen from the first selective light modulator layer and the second selective light modulator layer is deposited as a wet film comprising a solvent using a liquid coating process,
- wherein the method further comprises:
- evaporating the solvent from the wet film, wherein after evaporation of the solvent the at least one layer remains a liquid having a second viscosity that is greater than the first viscosity and exhibits a pseudoplastic behavior that allows self-leveling of the at least one layer;
- and subsequent to evaporation of the solvent but prior to the releasing the substrate from the sheet, curing the at least one layer to form a self-leveled, cured selective light modulator layer.
