Abstract

A lighted display assembly for an appliance includes interchangeable display screens. Multiple light sources flash, turn on and turn off to indicate a status of the appliance by illuminating a selected one of the display screens. A display grid extends between the light sources and the selected display screen and defines light passages that are each uniquely associated with a corresponding light source. Light emitted by each light source is confined to a discrete area of the display screen by the corresponding light passage. The discrete areas of the interchangeable display screens may include any of a variety of markings, for example, markings in a different language. The assemblies may be tailored to the needs of a particular customer by selecting an appropriate display screen.
