Spherical illuminant and display device

A display device, comprising:

• a plurality of moveable display units;
• and
• at least one external control device for emitting control signals in dependence on which at least some of the plurality of display units form a display, the display units each being connected at different locations via coupling means and capable of being detachably connected to one another,
• wherein at least some of the display units comprise at least one detection device for detecting a relative position of at least one further display unit, and
• wherein the at least one detection device is a sensor which detects at least one adjacent display unit,
• wherein the moveable display units are spherical illuminants comprising one or more of at least one energy storage device or an energy source for supplying one or more of the at least one external control device, the light source, the drive, and the coupling device with electrical energy,
• wherein each of the plurality of moveable display units comprises an electric motor which is configured to set each of the plurality of moveable display units in motion and bring the plurality of moveable display units to a specific stop by electromagnetic driving of a mechanical actuator outside the center of gravity of each of the plurality of moveable display units, and
• wherein the at least one external control device is integrated into at least one of the plurality of moveable display units so that the at least one of the plurality of moveable display units controls all of the plurality of moveable display units.
