ROTATING DISPLAY APPARATUS

WIPO Patent Application WO/2023/136382

A1

The present invention is applicable to the display apparatus-related technical field, and relates to, for example, a rotating display apparatus using a light-emitting diode (LED) which is a semiconductor light-emitting device. The present invention provides the rotating display apparatus comprising: a fixing portion including a motor; a rotating portion located on the fixing portion and rotated by the motor; a light source module including a light-emitting element array coupled to the rotating portion and displaying an image by using an afterimage caused by the rotation of the rotating portion; and an encoder positioned between the fixing portion and the rotating portion to synchronize an image displayed by the light-emitting element array at a predetermined position when the rotating portion rotates, wherein the encoder comprises: a light-emitting portion continuously emitting light; a light-receiving portion receiving light emitted from the light-emitting portion through at least two paths; and a disk-shaped scaler disposed between the light-emitting portion and the light-receiving portion and having a plurality of slits formed along the circumferential direction.
