Hybrid self illuminated and actively back lit signage for printed graphics
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 diffuser for providing diffusion in at least one direction;
a graphic on the diffuser;
a turning film having a first structured surface for redirecting light and a second surface opposite the first surface, wherein the turning film is on a side of the graphic opposite the diffuser and the first structured surface faces the graphic;
a reflector on the second surface of the turning film; and
an active backlight for actively backlighting the sign,
wherein the turning film directs light via the first structured surface from in front of the sign toward a viewer of the graphic in order to passively illuminate the sign when the active backlight is off.
2. The sign of claim 1 , further comprising an over-laminate securing the sign to a display surface.
3. A hybrid front lit shaped sign, comprising:
a turning film having a first structured surface for redirecting light and a second surface opposite the first surface;
a reflector on the second surface of the turning film; and
an active backlight for actively backlighting the sign,
wherein the turning film directs light via the first structured surface from in front of the sign toward a viewer of the sign in order to passively illuminate the sign when the active backlight is off,
wherein a shape of the sign from the viewer's perspective provides content to be conveyed to the viewer.
