Abstract
A method of making a laminated optically clear adhesive (OCA) assembly includes providing a first OCA component having a first thickness; providing a second OCA component having a second thickness; and laminating the first OCA component and the second OCA component using a roll to roll lamination process to form the laminated OCA assembly. The first OCA component and the second OCA component are laminated together at a nip roller assembly, the nip roller assembly using a nip roller pressure selected based on the total thickness of the first and second OCA components such that the nip roller pressure decreases as the total thickness of the first and second OCA components increases.
