Claim Text:
1. A gaming system display comprising: a first underlying display; and a second display disposed to overlay at least a portion of the first underlying display, the second display including a transmissive liquid crystal panel, a backlight assembly, and a switchable diffuser film layer assembly between the transmissive liquid crystal panel and the backlight assembly, the backlight assembly including a transmissive aperture behind which a corresponding portion of the first underlying display is positioned, and the switchable diffuser film layer assembly including a first film layer with an applied first voltage, a second film layer with an applied second voltage, and a liquid crystal layer positioned between the first and second film layer, wherein the second display further includes a supplemental backlight directed to the aperture; and wherein the first film layer of the switchable diffuser film layer assembly includes a segmenting gap defining an aperture area electrically insulated from the remainder of the first film layer, the aperture area having an applied aperture voltage; wherein a region of the liquid crystal layer corresponding to the aperture area is transparent in a first mode where the aperture voltage and the second voltage are in opposite voltage polarity to allow viewing of the at least a portion of the first display, and the region of the liquid crystal layer corresponding to the aperture area is translucent in a second mode where the aperture voltage and the second voltage are in common voltage polarity to obscure the transmissive aperture.
