Abstract

See full text

A gaming system including an electronic gaming machine (EGM) having a multi-layer display is described. In particular, the EGM can be configured with a display that provides a 3D-like image. An acousto-optical modulator interstitial component can be positioned between two liquid crystal displays to mitigate moiré interference. A piezoelectric transducer can be attached to a glass interstitial component or to a display panel of a multi-layer display in order to control the moiré interference.
