Abstract:
A gaming system includes a first display configured to display the random outcome of the wagering game, and a second display disposed to overlay at least a portion of the first display. The second display includes a transmissive liquid crystal display defining a transmissive window behind which a corresponding portion of the first display is positioned. The liquid crystal display further includes a polarizing film having a plurality of patterned features generally aligned with the transmissive window. The polarizing film is at least partially removed in the area of the patterned features to enhance transmissivity of the liquid crystal display.
