Abstract
An optical stack and related electronic display assemblies and methods are disclosed. The optical stack includes a sub-stack. The sub-stack includes a micro lens array (“MLA”) and a liquid crystal (“LC”) layer. The MLA and the LC layer are directly or indirectly bonded to one another as part of the sub-stack.
Claims17
An optical stack comprising:
- a first polarizer;
- a micro lens array (“MLA”) bonded to a rear surface of the first polarizer;
- a liquid crystal layer (“LC layer”);
- a second polarizer bonded to a forward surface of the LC layer, wherein the MLA, the LC layer, the first polarizer, and the second polarizer form, at least in part, a sub-stack, where components of the sub-stack, including at least the MLA, the LC layer, the first polarizer, and the second polarizer are directly or indirectly bonded to one another;
- a third polarizer located rearward of, and separate from, the sub-stack;
- and
- a prism film located rearward of the third polarizer, where the prism film is separate from the sub-stack.
