This paper proposes an optical system for two-view aerial signage over an LED panel. A retro-reflective slit array and a beam splitter are placed in front of the LED panel and form the aerial image over the LED panel. The aerial signage shows different apparent images depending on the viewing directions. Showing aerial signage right in front of an LED panel reduces the foot space, which is suitable for a large-scale installation.
