Abstract:
Self illuminated back and front lit signage for a printed graphic. The signage includes a turning film having a structured surface for redirecting light, a diffuser providing for diffusion, and a printed graphic. The turning film receives light from an ambient light source and directs the light via the structured surface toward a viewer of the graphic in order to passively illuminate the signage.
