Optical assembly and the method to make the same
First Claim
1. A method of forming an optical assembly, comprising:
- providing a first optical film comprising a first surface;
forming an adhesive layer on the first surface of the first optical film, wherein the adhesive layer is made of a first material;
providing a second optical film comprising a second surface, wherein the second surface of the second optical film comprises a plurality of prisms, wherein the plurality of prisms are made of a second material; and
bonding the plurality of prisms to the adhesive layer by controlling a difference between the surface tension of the first material and the surface tension of the second material, wherein the difference is greater than 3 dyne/cm such that the adhesive force between the adhesive layer and the plurality of prisms is greater than 100 g/25 mm and the optical gain of the optical assembly is greater than 1.5 when the first material and the second material are fully cured.

Abstract
The present invention discloses an optical assembly. The optical assembly comprises: a first optical film comprising a first surface; an adhesive disposed on the first surface of the first optical film; and a second optical film comprising a second surface, wherein the second surface of the second optical film comprises a plurality of microstructures, wherein the plurality of microstructures are bonded to the adhesive; wherein the adhesive is made of a first material and the plurality of microstructures are made of a second material, wherein the hydrophilic/hydrophobic characteristic of the first material is configured with respect to the hydrophilic/hydrophobic characteristic of the second material such that the adhesive force between the adhesive and the plurality of microstructures of the second optical film is greater than 100 g/25 mm and the optical gain of the optical assembly is greater than 1.5.
