Display device using a light guide for exterior automotive lighting

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;
• and
• a light guide surface extending from the light source substantially along the first direction, the light guide surface being opposite the light emitting surface;
• and
• the 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.
