l Electronic Display) ”Taiwan patent application No. 85,
202,605, US Pat. No. 5,818,401 and Chinese patent ZL96229136. In these patent applications, multiple rows of light emitting devices are mounted on a rotating body at equal distances or angles. Each row of light emitting devices includes a number of light emitting sources. When the rotating body rotates, different light sources of each light emitting device are excited at different spatial positions. As a result of the afterimage of the image that occurs in the human eye, a virtual display is created on the rotating surface of the rotating body.
