Abstract: The present invention provides an operation system for a display framework for motion picture for advertisement and decoration. The display framework includes a base, a bottom frame, a side frame, a picture frame. The operation system is provided between the bottom frame and the bottom of picture, which includes a motor and a transmission unit. The operation is: the motor provides rotational movement to a gearwheel assembly through a transmission unit, then initiates the movement of a control gearwheel, a first direction guiding gearwheel, a second direction guiding gearwheel, a bridging gearwheel, a motion actuating gearwheel, and a motion actuator which undergoes linear reciprocal movement. The motion actuator provides the linear movement of the bottom of picture. It is easy to replace the picture of the display framework of the present invention and both the front and rear sides of the picture frames can be viewed.
