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.

Description

technical field [0001] The invention relates to a pressure-sensitive adhesive, in particular to an optical-grade composite pressure-sensitive adhesive suitable for touch devices, display devices and touch display screens. Background technique [0002] The touch display screen combines touch technology and display technology, and is widely used in electronic devices for both input and display. Figure 1A A side-view stacking view of a conventional touch display screen is shown, which includes a display module 10 and a touch module 12 , and a gasket 11 between them for light-shielding and dust-proof purposes. Since the air medium in the gasket 11 has a different refractive index from the display module 10 and the touch module 12 on both sides, it will cause partial reflection of light, thereby reducing the light penetration and affecting the contrast of the image. [0003] In order to improve this problem, there are Figure 1B Presentation of the architecture shown. exist ...
