IT之家 10 月 28 日消息，美国专利商标局（USPTO）现已公布了联想旗下摩托罗拉的一项全新专利，显示该公司正在研发一种可穿戴“卷轴拉伸屏”智能手表，当用户需要查看更多内容时，可以从手腕上摘下手表，设备将自动延展屏幕，让用户获得类似智能手机的阅读体验。
专利图纸显示，该设备采用柔性可伸缩显示屏，匹配提供伸缩 / 折叠功能的铰链，同时配备传感器以帮助设备实时调整屏幕尺寸。从而实现“佩戴时拥有智能手表的便利，按需获得大屏视觉体验”。
目前，对于这款产品的更多技术细节暂不得而知，相应专利文档的焦点主要集中于屏幕设计方面，该机事实上也并不一定会正式量产，仅透露了联想 / 摩托罗拉在可穿戴技术上的研发方向。
