Timepiece display mechanism, for a watch, comprising a roller pivoting about a main axis and comprising flaps, each pivoting about a secondary axis parallel to the main axis and having two faces, first drive means for pivoting the roller about the main axis, and second drive means for pivoting a flap about its secondary axis, in a determined position of this secondary axis relative to the main axis, and which include, at each flap, a drive pinion cooperating with a control means to modify, in sequence or continuously, the position of the successive flaps of the same roller or to modify, on demand, the position of a specific flap.

The present disclosure is applicable to a 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. According to the present disclosure, a rotating display apparatus using a light-emitting device, comprises: a fixed part including a motor; a rotary part located on the fixed part and rotated by the motor; and a light source module which is coupled to the rotary part, and which includes at least one panel that is radially arranged or at least one panel that is arranged along the cylindrical surface, and a first light-emitting device array having individual pixels that are arranged on each panel in the longitudinal direction, wherein sub-pixels forming the individual pixel of the first light-emitting device array can be arranged along a direction orthogonal to the longitudinal direction.

Gaming systems, methods, and machines provided herein may include wheel displays with movable wheel segments that may be caused to have at least portions thereof that at least translate along axes parallel to a center axis of the wheel display when the wheel is in a “spin” mode.

An event display board for displaying important events in a person's life is disclosed. The display board comprises of combinations of words and numbers printed on wheels and viewable through display windows. The words or numbers displayed through the windows may be changed by rotating the wheels until the desired words or numbers show through the display windows and the words or numbers on each wheel line up with corresponding words or numbers on adjacent wheels to form phrases appropriate for the event so they can be displayed and photographed.
