Hybrid signage capable of self illumination and having an active backlight. The signage includes a turning film having a structured surface for redirecting light in order to passively illuminate a printed graphic or shaped sign when the backlight is off. In the shaped sign, the shape provides the content, such as letters, to be conveyed to the viewer instead of a graphic. The signage can be actively illuminated when the backlight is on to supplemental the passive illumination.

A system for on-product projection and display of electronic content. The system includes a projector for projecting electronic content, a mirror film stack having a reflective surface facing the projector, and a product having an exterior surface facing the reflective surface of the mirror film stack. A graphic is located on a surface of the mirror film stack opposite the reflective surface. The electronic content from the projector is projected onto the exterior surface of the product via the reflective surface of the mirror film stack. The graphic can be located on a display window and hide the mirror from a viewer without completely blocking a view of the projected electronic content. The product can include a removable projection screen for displaying the electronic content, and the projection screen can include a removable label on its non-viewer side to advertise or promote the product.
