Research progress on optical adhesive for electronic display screen
The touch display screens of cell phones,tablet PCs,smart watches,and other electronic products are composed of many complex thin layers with different structures and functions,in which optical adhesive plays an important role.With the iteration of screen technology,the touch display screen is developing in the direction of edge-to-edge screen,foldable screen,as well as curled and stretchable screen,which puts forward higher requirements for optical adhesive.In this review,the characteristics and research status of polyurethane optical adhesive,epoxy resin optical adhesive,acrylate optical adhesive,and silicone resin optical adhesive for 3C product screens were introduced,and the development and problems of various types of optical adhesive were discussed.An in-depth exploration was conducted on the preparation and properties of acrylate optical pressure-sensitive adhesive,and the latest research progress on optical pressure-sensitive adhesive for flexible foldable screens in recent years was summarized.The application,challenges,and future development directions of optical pressure-sensitive adhesive for electronic display screen were proposed,providing reference for subsequent research work.
