裸眼三维（3D）显示器是改变游戏规则的技术之一，它将重新定义便携式电子设备的显示行业。然而，由于最先进的显示面板的分辨率有限，目前的3D显示在空间分辨率、角度分辨率和视角之间进行了关键的权衡。受脊椎动物眼睛的空间变分辨率成像启发，我们提出了具有空间变信息密度的三维显示。在中心视图中保持平滑运动视差的立体体验，而在外围视图中扩大视角。它是由一个大规模的2d合成复杂操作点/线性/矩形混合形状视图。此外，还演示了具有前所未有的160°水平视角的视频速率全彩色3D显示器。该3D系统具有轻薄的外形，可以与现成的平板集成，在便携式电子产品中应用前景广阔。通过大规模的二维聚合复合体实现了具有超宽视场的空间变信息密度三维显示，在便携式电子设备中显示出巨大的潜力。
Glasses-free three-dimensional (3D) displays are one of the game-changing technologies that will redefine the display industry in portable electronic devices. However, because of the limited resolution in state-of-the-art display panels, current 3D displays suffer from a critical trade-off among the spatial resolution, angular resolution, and viewing angle. Inspired by the so-called spatially variant resolution imaging found in vertebrate eyes, we propose 3D display with spatially variant information density. Stereoscopic experiences with smooth motion parallax are maintained at the central view, while the viewing angle is enlarged at the periphery view. It is enabled by a large-scale 2D-metagrating complex to manipulate dot/linear/rectangular hybrid shaped views. Furthermore, a video rate full-color 3D display with an unprecedented 160° horizontal viewing angle is demonstrated. With thin and light form factors, the proposed 3D system can be integrated with off-the-shelf purchased flat panels, making it promising for applications in portable electronics. A space-variant information density three-dimensional display with ultrawide field of view is achieved by a large-scale 2D-metagrating complex, which shows great potential for portable electronic devices.
