A display apparatus is disclosed. The display apparatus according to an embodiment of the present disclosure includes: a case; a motor disposed in the case; a rotation plate rotated by the motor; a plurality of light source bars disposed on the rotation plate, and including a plurality of light sources vertically arranged; a fixed plate spaced below the rotation plate; a first and a second infrared (IR) output device disposed on the fixed plate; and a first and a second IR receiving device disposed on the rotation plate. Accordingly, a rotatable display apparatus, capable of reducing image blur during image display based on an afterimage, may be implemented.

A flag actuation system for a lighting fixture is disclosed. The flag actuation system includes an actuator, an actuator axle connected to and drivable by the actuator, and at least two flags, each flag being movable between a first position in which the flag is arranged in an optical path defined by the flag actuation system, and a second position in which the flag is arranged out of the optical path. Each flag is individually and detachably connectable to the actuator axle via a magnetic actuator connection, and each flag is retainable in the first position using a first magnetic retaining connection and in the second position using a second magnetic retaining connection.
