Abstract: The persistence of vision rotary display device is a display that presents 2-D and 3-D images that appear to float in midair through the timely energization of a plurality of LEDs that travel in circular paths on a rotor. The rotor is driven by a motor mounted in a stator; the stator may be mounted to a fixed structure or held in a user's hand. The device achieves a resolution that is not limited by the physical size of the LEDs by mounting LEDs on multiple arms with a different offset from the center on each arm. Control electronics in the rotor map the image to polar format and adjust the timing of the LEDs to compensate for the fact that they may be on different arms. The device may present moving images by changing the image at a predetermined frame rate.
