Screen scratch detection

5G时代，除了体验更佳的网速之外，追求更流畅的视界，即拥有更高刷新率的屏幕成为手机、平板等3C电子产品的核心技术和功能，意味动画过渡效果更顺滑，极大改善视觉和操作体验。故对高刷新率屏幕的研究成为行业热点。

高刷新率的屏幕意味着延迟更低。如标准60HZ刷新率的屏幕延迟为16.67ms, 预计2023年上市的480HZ高刷屏延迟理论降低8倍，仅2.08ms。高刷屏生产工艺检测中需借助高速摄像机，记录2帧关键图像记录时间戳的方式，对延迟时间是否达标进行检测。

京东方科技集团股份有限公司，使用千眼狼千帧级高速摄像机，在无法补光的环境下，采用2倍增益，清晰拍摄慢放视频，计算跟手延迟。
