Abstract
The present invention is directed to an optical level composite pressure-sensitive adhesive (PSA), which includes a first portion and a second portion, which have different crosslinked densities and together form a mono-composite structure. The first portion and the second portion may be respectively bonded to a first lamination layer and a second lamination layer that are heterogeneous to each other. Accordingly, different interfacial adhesion and bulk rheology are generated at the interface of the first portion/first, lamination layer and the interface of the second portion/second lamination layer.
Claims27
An optical level composite pressure-sensitive adhesive (PSA), comprising:
- a first portion;
- and
- a second portion having a crosslinked density less than a crosslinked density of the first portion, wherein the first portion and the second portion together form a mono-composite structure;
- wherein the first portion and the second portion may be bonded to a first lamination layer and a second lamination layer respectively that are heterogeneous to each other.
An apparatus with an optical level composite pressure sensitive adhesive, the apparatus being adapted as a touch apparatus, comprising:
- a touch substrate;
- a cover lens disposed above the touch substrate;
- and
- a composite pressure-sensitive adhesive (PSA) bonded between the cover lens and the touch substrate;
- wherein the composite PSA includes a first portion and a second portion that together form a mono-composite structure, and the first portion has a crosslinked density greater than a crosslinked density of the second portion.
An apparatus with an optical level composite pressure-sensitive adhesive, the apparatus being adapted as a display apparatus, comprising:
- at least one polarizer;
- a display module including at least one glass layer and a cell layer;
- and
- at least one composite pressure-sensitive adhesive (PSA) bonded between the polarizer and the display module;
- wherein the composite PSA includes a first portion and a second portion that together form a mono-composite structure, and the first portion has a crosslinked density greater than a crosslinked density of the second portion;
- and
- wherein the first portion is bonded to the polarizer and the second portion is bonded to the display module.
An apparatus with an optical level composite pressure-sensitive adhesive, the apparatus being adapted as a touch-display screen, comprising:
- a touch apparatus;
- a display apparatus;
- and
- a composite pressure-sensitive adhesive (PSA) bonded between the touch apparatus and the display apparatus;
- wherein the composite PSA includes a first portion and a second portion that together form a mono-composite structure, and the first portion has a crosslinked density different from a crosslinked density of the second portion.
