摘　　要：近年来,触摸屏作为一种最简单的人机交互方式,正在快速取代传统的电子显示屏。光学透明胶(OCA)是一种无色透明、具有高透光率和高粘接力的光学压敏胶,被广泛应用于触摸屏各层屏体间的贴合。OCA能有效地提升触控屏的光学效果、触控灵敏性和机械可靠性,减少屏幕眩光,给使用者更好的视觉体验。本文系统地介绍了OCA的特点、分类、固化方式、粘接机理以及技术进展,探讨了目前OCA材料存在的问题,并对其未来发展前景进行了展望。As one of the simplest ways of human-computer interaction,touch screen is rapidly replacing the traditional electronic display in recent years.Optically clear adhesive(OCA)is a transparent optical pressure-sensitive adhesive with high light transmittance and considerable adhesion,which is widely used to bond different layers of touch screen.OCA can effectively enhance the optical effect,touch responsiveness,and mechanical reliability of touch screen,reduce screen glare,and provide better visual experience for users.In this paper,the characteristics,classification,curing methods,bonding mechanisms,and technical progress of OCA were systematically introduced,and its future development prospects were also discussed.
