Spherical Drone Display’ Crosses UAV with LEDs

Japanese mobile services provider NTT DOCOMO Inc. has developed a spherical drone display: an unmanned aerial vehicle (UAV) that displays LED images on an omnidirectional spherical screen while in flight. The device comprises a spherical external frame and an internal LED frame consisting of a series of eight curved LED strips that extend from top to bottom, a drone fitted inside the sphere and legs protruding underneath. During flight, the LED frame spins on its axis in a rapid horizontal motion, forming an afterimage effect to create the illusion of a solid sphere of motionless LEDs.
