 背景技术
柔性可折叠显示装置越来越受市场的青睐，柔性屏手机是指采用可弯曲、柔韧性佳的屏幕的手机，相较于传统屏幕，柔性屏幕优势明显，不仅为用户提供全新的使用效果，而且体积上更为小巧，功耗更低，同时屏幕具有柔韧性，减小屏幕破裂的风险。
折叠铰链是实现柔性显示装置可折叠特性的重要组件，它在屏幕保护、折叠同步等方面起着重要作用。目前，折叠铰链在实现折叠同步方面的方法是设置包含有多个相互配合的齿轮的同步结构，齿轮同步结构中的各个齿轮通过相互啮合实现协调转动，进而带动两侧的柔性屏幕同步折叠。但是，齿轮在转动过程中由于啮合精度的因素而出现顿挫感，且容易造成齿轮的齿部损坏，进而影响显示装置同步折叠的流畅性。
