The light guide plate is formed from a single piece of material that is transparent to visible light. The light guide plate includes a center opening extending between its front and rear surfaces and defining an inner sidewall. The light source is configured to emit visible light and is positioned facing the inner sidewall so that light emitted therefrom passes through the inner sidewall and into the light guide plate. A pattern is formed in the light guide plate and positioned to be illuminated by the visible light emitted from the light source so that the illuminated pattern is visible through the front surface of the light guide plate. The lighting display assembly is mounted behind a display monitor and is sized to extend laterally beyond an outer peripheral edge of the display monitor such that the illuminated pattern is visible from in front of the display monitor. ## Claims ### Claim 1 A lighting display assembly comprising: a light guide plate comprising a front surface, a rear surface, and an opening that extends through the light guide plate from the front surface to the rear surface and defines an inner sidewall of the light guide plate; and a light source facing the inner sidewall, the light source configured to emit visible light that passes through the inner sidewall and into the light guide plate and illuminates a pattern in the light guide plate so that the pattern is visible through the front surface of the light guide plate. ### Claim 2 (depends on 1) The lighting display assembly of claim 1, further comprising a controller configured to control the light source. ### Claim 3 (depends on 1) The lighting display assembly of claim 1, wherein the opening defines a plurality of inner sidewalls and a beveled corner between two inner sidewalls of the plurality of sidewalls. ### Claim 4 (depends on 3) The lighting display assembly of claim 3, wherein: the lighting source comprises a plurality of light emitting devices; and the plurality of light emitting devices comprises first light emitting devices positioned along the plurality of sidewalls at a first spacing and second light emitting devices positioned along the beveled corner at a second spacing that is reduced with respect to the first spacing. ### Claim 5 (depends on 1) The lighting display assembly of claim 1, wherein the pattern in the light guide plate redirects at least a portion of the visible light emitted from the light source towards the front surface of the light guide plate. ### Claim 6 (depends on 1) The lighting display assembly of claim 1, wherein the light guide plate is configured to be mounted behind a display monitor and is sized to extend laterally beyond an outer peripheral edge of the display monitor such that the pattern is visible from in front of the display monitor. ### Claim 7 (depends on 1) The lighting display assembly of claim 1, further comprises a rear panel, wherein: the light guide plate is mounted to the rear panel; and the light source is mounted to the rear panel. ### Claim 8 (depends on 7) The lighting display assembly of claim 7, further comprising: one or more brackets; wherein the light source comprises a plurality of light emitting diodes; and wherein the one or more brackets mount the plurality of light emitting diodes to the rear panel. ### Claim 9 (depends on 1) The lighting display assembly of claim 1, wherein the pattern is formed in the rear surface of the light guide plate. ### Claim 10 (depends on 1) The lighting display assembly of claim 1, wherein the pattern is screen printed onto the rear surface of the light guide plate. ### Claim 11 A gaming machine comprising: a cabinet; a display monitor supported by the cabinet and having an outer peripheral edge; a lighting display assembly positioned behind the display monitor and comprising: a light guide plate comprising a front surface, a rear surface, and an opening that extends through the light guide plate from the front surface to the rear surface and defines an inner sidewall of the light guide plate; and a light source facing the inner sidewall, the light source configured to emit visible light that passes through the inner sidewall and into the light guide plate and illuminates a pattern in the light guide plate so that the pattern is visible through the front surface of the light guide plate; and a controller configured to control the light source. ### Claim 12 (depends on 11) The gaming machine of claim 11, wherein the opening further defines a plurality of inner sidewalls and a beveled corner between two inner sidewalls of the plurality of sidewalls. ### Claim 13 (depends on 12) The gaming machine of claim 12, wherein: the lighting source comprises a plurality of light emitting devices; and the plurality of light emitting devices comprises first light emitting devices positioned along the plurality of sidewalls at a first spacing and second light emitting devices positioned along the beveled corner at a second spacing that is reduced with respect to the first spacing. ### Claim 14 (depends on 11) The gaming machine of claim 11, wherein the light guide plate extends laterally beyond the outer peripheral edge of the display monitor such that the pattern is visible from in front of the display monitor. ### Claim 15 (depends on 11) The gaming machine of claim 11, further comprising: a lift arm assembly that extends through the opening through the light guide plate and connects the display monitor to the cabinet; and wherein the lift arm assembly permits moving the display monitor between a lowered operating position and a raised servicing position. ### Claim 16 (depends on 15) The gaming machine of claim 15, wherein an interior of the cabinet is exposed via the opening when the display monitor is moved to the raised servicing position. ### Claim 17 A gaming machine comprising: a cabinet; a display monitor supported by the cabinet and having an outer peripheral edge; a lighting display assembly positioned behind the display monitor and comprising: a light guide plate comprising a front surface, a rear surface, outer edges joining the front surface to the rear surface, and inner sidewalls opposite the outer edges; and light emitting devices positioned to emit visible light through the inner sidewalls of the light guide plate and toward the outer edges of the light guide plate, wherein the emitted light illuminates and makes visible a pattern of the light guide plate through the front surface of the light guide plate; and a controller configured to control the light emitting devices. ### Claim 18 (depends on 17) The gaming machine of claim 17, wherein the light guide plate further comprises beveled corners between respective inner sidewalls. ### Claim 19 (depends on 18) The gaming machine of claim 18, wherein the light emitting devices are positioned along the inner sidewalls at a first spacing and along the beveled corners at a second spacing that is reduced with respect to the first spacing. ### Claim 20 (depends on 17) The gaming machine of claim 17, further comprising: a lift arm assembly that extends through the light guide plate and connects the display monitor to the cabinet; wherein the lift arm assembly permits moving the display monitor between a lowered operating position and a raised servicing position; and wherein an interior of the cabinet is exposed when the display monitor is moved to the raised servicing position.
