Patent ID: 10663791

Abstract:
A material system for a surface display unit that includes a first side (i.e., a proximal side) that faces a viewer of the surface display unit and a second side (i.e., a distal side) facing away from the viewer. The material system provides at least three appearance states, including a generally opaque first appearance state when the surface display unit is “off” (i.e., not used to display images), a second appearance state in which the material system is illuminated from the first (i.e., proximal) side to display a first image (e.g., information and/or decoration) that is perceptible to the viewer, and a third appearance state in which the material system is illuminated from the second (i.e., distal) side to display a second image (e.g., information and/or decoration) that is perceptible to the viewer. Surface display units, systems, and methods comprising the material system are also disclosed.
