Abstract
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.
在 LED 面板上使用条纹式逆反射器的紧凑型空中显示屏采用了改善图像间隙和窄视角的两种技术。通过垂直于条纹方向的图像滚动，消除了条纹式逆反射器结构造成的空中图像间隙。通过增加条纹式逆反射器的宽度，成功改善了紧凑型空中显示屏固有的窄视角问题，这一点已通过理论计算和测量得到验证。对节省空间的紧凑型航空显示器的这些改进将极大地扩展其应用领域，如数字标牌和非接触式界面。
