A button deck for an electronic gaming machine (EGM) may have a display system that includes one or more curved display portions. A curved display portion may be curved along an axis that is substantially horizontal when the button deck module is coupled to an EGM. In some examples, a curved display portion may reside along a side of the button deck module that is near (or touching) a player when the button deck module is in use. In some implementations, a curved display portion may be proximate a gaming machine display or a player tracking module when the button deck module is coupled to the EGM. The curvature of a curved display portion may match the curvature of a gaming machine display device. At least a portion of the button deck may be configured to display images corresponding to a game theme and/or an attract sequence.
