A display device is provided for providing lighting in exterior and interior lighting applications, such as for center high mount stop lights (CHMSL) and other automotive lighting applications. The display device uses a light guide having light couplers on a light source end for receiving light from at least one light source. The light guide extends from the light source end with a light emitting surface and a light guide surface opposite the light emitting surface. The light emitting surface and the light guide surface extend in a direction substantially parallel to the direction of the light received from the light source. The light guide surface has a plurality of surface sections extending at angles relative to one another. The surface sections may be angled at alternating sections direct light towards the light emitting surface using total internal reflection.

[ We claim:] [1.]1. A display device comprising:at least one light source operable to radiate a light in a first direction;at least one light coupler adjacent the at least one light source to receive the light, the at least one light coupler being operable to distribute the light in the first direction;a light guide comprising a substrate material, the light guide having:a light source end adjacent the at least one light coupler to receive the distributed light;a light emitting surface extending from the light source end substantially along the first direction; anda light guide surface extending from the light source substantially along the first direction, the light guide surface being opposite the light emitting surface; andthe light guide surface comprising a plurality of first surface sections, the first surface sections extending substantially non-parallel to the light emitting surface and each first surface section separated by at least one of a plurality of second surface sections, the second surface sections extending substantially non-parallel to the light emitting surface, the first surface sections extending at different angles from the second surface sections, at least one of the first and second surface sections being at a reflective angle to provide reflection of the light generated by the light source at the at least one first and second surface sections, the reflective angle of the at least one of the first and second surface sections further providing for refraction of the reflected light at the light emitting surface with a light distribution spread in a second direction.
