Two technologies for improving image gaps and narrow viewing angle were applied to a space-saving compact aerial display with striped retro-reflector on a LED panel. The aerial image gaps created by the striped retro-reflector structure was smoothed by scrolling the images perpendicular to the stripe direction. The narrow viewing angle inherent to the compact aerial display was successfully improved by increasing the width of the striped retro-reflector, verified by both theoretical calculation and measurement. These improvements in the space-saving compact aerial display would greatly expand its applications, such as digital signage and touchless interface.

将两种改善图像间隙和窄视角的技术应用于节省空间的紧凑型航空显示器，该显示器在 LED 面板上带有条纹回复反射器。通过垂直于条带化方向滚动图像，可以平滑由条纹回复反射器结构创建的航空图像间隙。通过增加条纹回复反射器的宽度，成功地改善了紧凑型航拍显示器固有的窄视角，并通过理论计算和测量进行了验证。节省空间的紧凑型航空显示器的这些改进将大大扩展其应用，例如数字标牌和非接触式界面。
