Document Type and Number:
WIPO Patent Application WO/2021/060594
Kind Code:
A1
Abstract:
The present invention can be applied to display device-related technical fields and relates to a rotatable display device using, for example, light-emitting diodes (LEDs), which are semiconductor light-emitting diodes. According to the present invention, the rotatable display device using light-emitting diodes may comprise: a fixing unit comprising a motor; a rotation unit which is provided on the fixing unit and has a first side coupled to the motor and a second side rotatably coupled to a rotation coupling part, and rotates, the second side being a side opposite to the first side; and a light source module provided in the rotation unit and comprising at least one panel provided along a virtual cylindrical outer circumferential surface thereof and a light-emitting diode array in which individual pixels are provided on each panel in the longitudinal direction.
