According to the patent document, the technology that was granted a patent on February 13, 2018 was named "Flying Display Device" (flying display terminal), which was filed by Samsung Display in January 2016 . Since the main body (10) is equipped with a "display unit" (100) and has a "flight unit" (110) comprising a joint part (113) and a propeller (112) , The display body is supposed to float in the air like a drone as it is.


The joint part (113) makes it possible to hold the display standing by attaching an angle. In addition, by controlling the movement of the display according to the movement of the viewer's eyes, a mechanism that allows the display to be easily readable at all times is incorporated. Illustrations are shown by solid and broken lines in the following figures, but the part of the broken line is "the position adjusted according to eye movements".


Furthermore, it is possible to wake up only the display part while keeping the main body horizontal.


The body is equipped with a GPS sensor and surrounding obstacle sensor, voice control and Wi-Fi transmission and reception are also possible. With these mechanisms, this drone type display can always be positioned directly in front of the viewer and display information. Although there is no particular mention about the actual use that I care about, The Verge is sure to fly in front of the person walking in the street and display the targeted advertisement suitable for that person. That's a bad future story, "he says.
