Interchangeable display assembly

A lighted display assembly comprising:

• a one-piece display grid including an upper surface and a lower surface spaced from the upper surface, the display grid defining at least two separate, hollow light passages within said display grid and extending completely through said display grid from said lower surface to said upper surface, wherein each light passage defines a hollow channel, each of the light passages having a sidewall extending continuously between a first end at the lower surface and a second end at the upper surface;
• a plurality of light sources mounted on a circuit board, each of the light sources uniquely associated with one of the at least two light passages, each of the light sources positioned proximate the first end of the corresponding light passage;
• and
• an interchangeable display screen positioned proximate the second ends of the at least two light passages, and
• a gasket positioned between the circuit board and the display grid relative to the at least two light sources wherein the gasket defines apertures aligned with the light sources.

A method for assembling a lighted display comprising:

• providing at least two light sources;
• mounting the at least two light sources to a circuit board;
• positioning a gasket on the circuit board, the gasket defining apertures aligned with the light sources;
• positioning a one-piece display grid on the gasket relative to the at least two light sources so that each of at least two hollow light passages defined within the display grid is uniquely associated with at least one light source, wherein the display grid includes an upper surface and a lower surface and the at least two hollow light passages are discrete channels that extend completely through the display grid from the upper surface to the lower surface;
• securing an interchangeable display screen to the upper surface of the display grid so that the light sources illuminate the interchangeable display screen.
