LCD DISPLAY FOR GAMING DEVICE WITH INCREASED APPARENT BRIGHTNESS
First Claim
1. A gaming device, comprising:
- a first display assembly that includes;
a light source that produces light,a projection means that produces a projected image with polarized light,a substrate configured to display at least part of a random outcome of the wagering game using the polarized light; and
a second display overlaying at least a portion of the substrate such that at least part of the substrate is visible through the second display when the polarized light is permitted to pass through the second display, the second display including a liquid crystal layer that receives the polarized light and a front polarizing film that is configured to re-polarize the polarized light.

Abstract
A display system in which a display assembly has enhanced apparent brightness when viewed through a second display overlaying the display assembly. The display assembly includes a liquid crystal (LC) based projector having a light source and a polarizing film that polarizes the light. A curved projection screen is positioned in front of the LC-based projector to receive polarized light and display a wagering game. The second display is positioned to overlay at least a portion of the curved projection screen such that at least part of the second display is visible through the second display when the polarized light from the projection screen is permitted to pass through the second display. The second display includes a liquid crystal layer and a front polarizing film that affects whether the polarized light is permitted to pass through or is blocked. An apparent brightness increase of 30% or more is achieved compared to conventional displays that include both a front and rear polarizer. The second display can also include a rear polarizer. The polarization of the polarized light must match the polarization of the light through the rear polarizer so that the liquid crystal layer is illuminated with uniformly polarized light.

12. A display system for a gaming device, comprising:
-
a liquid crystal (LC) based projector including a light source that produces light and a polarizing means that causes the light passing through the polarizing means to be polarized; a projection screen positioned in front of the LC-based projector, the projection screen receiving images relating to a wagering game played on the gaming device, the images being illuminated by the polarized light and including a representation of a randomly selected game outcome of the wagering game; a transparent second display positioned to overlay at least portion of the projection screen such a window area of the projection screen is visible through the second display when the polarized light is permitted to pass through the second display, the second display including a liquid crystal array that receives the polarized light passing through the projection screen and a front polarizing film adjacent the liquid crystal layer and distal from the projection screen. - View Dependent Claims (13, 14, 15, 16, 17)

18. A gaming device, comprising:
-
means for polarizing light; means for displaying a randomly determined outcome of the wagering game using the polarized light; liquid crystal means for receiving the polarized light passing through the means for displaying, the gaming device lacking a polarizer in a viewable window area between the means for displaying and the liquid crystal means such that the orientation of the light is unchanged between the means for displaying and the liquid crystal means. - View Dependent Claims (19)

20. A method of increasing the brightness of a first display visible through a window area of a second display, comprising:
-
positioning a polarizing film behind the first display such that light passing through the polarizing film is polarized and illuminates images displayed on the first display, the images representing at least part of a randomly selected outcome of a wagering game; configuring the second display such that the second display lacks a polarizer on at least a portion of a surface that faces the first display; positioning the second display in front of the first display such that the polarized light passing through the first display is received through the window area by a liquid crystal array of the second display facing the first display. - View Dependent Claims (21, 22, 23)
