Transmissive display having multiple switchable regions of a diffuser film layer assembly

摘要

A switchable transmissive display for a gaming system has an underlying display mode and a full video mode. The switchable transmissive display includes a first underlying display and a second display overlaying the first display. The second display includes a transmissive liquid crystal panel, a backlight assembly and a switchable diffuser film layer. The backlight assembly includes a transmissive aperture behind which the first underlying display is positioned. The second display also includes a supplemental backlight directed at the aperture. The second display has a first mode where the switchable diffuser film layer is transparent to allow viewing the first display and a second mode where the switchable diffuser film layer is translucent to obscure the transmissive aperture and an image is displayed. The switchable diffuser film layer distributes light to provide substantially homogeneous light intensity across the back of the transmissive liquid crystal panel.

主权项

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.
