Abstract
A graphic display apparatus including a substrate including a first major surface and a second major surface, the substrate configured to transmit light when the graphic display apparatus is in a transmissive mode and reflect light when the graphic display apparatus is in a reflective mode; a reflective layer positioned on the first major surface of the substrate; a tint layer positioned on the second major surface; a diffuser layer including an image that is positioned on the tint layer such that the diffuser layer and the substrate sandwich the tint layer; and a light source located proximate the diffuser layer such that the light source and the diffuser layer sandwich the image, wherein, when the graphic display apparatus is in the transmissive mode, the light source illuminates the image such that the image is viewable from the first major surface of the substrate, and when the graphic display apparatus is in the reflective mode, the image is not illuminated by the light source and is not viewable from the first major surface of the substrate.
