LCD DISPLAY FOR GAMING DEVICE WITH INCREASED APPARENT BRIGHTNESS

摘要

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.
