Abstract
A display includes a plurality of first light sources arranged in a first region; a plurality of lenses arranged in a second region over the first region; a plurality of opaque areas and a plurality of light transmissive areas arranged in a third region over the second region. Each light source of the plurality of first light sources is configured to direct light onto a lens of the plurality of lenses and each lens of the plurality of lenses is configured to receive light from a first light source of the plurality of first light sources and to direct the light through a light transmissive area of the plurality of light transmissive areas.
Claims16
A display comprising:
- a plurality of first light sources arranged in a first region;
- a plurality of lenses arranged in a second region over the first region a plurality of opaque areas and a plurality of light transmissive areas arranged in a third region over the second region;
- wherein each light source of the plurality of first light sources is configured to direct light onto a lens of the plurality of lenses
- wherein each lens of the plurality of lenses is configured to receive light from a first light source of the plurality of first light sources and to direct the light through a light transmissive area of the plurality of light transmissive areas;
- wherein the plurality of opaque areas are a plurality of second light sources wherein each lens of the plurality of lenses is configured to receive light from a first light source of the plurality of first light sources and to emit the light toward a light transmissive area of the plurality of light transmissive areas;
- wherein each lens of the plurality of lenses has a refraction characteristic and a distance to the light transmissive area of the plurality of light transmissive areas and
- wherein the each lens of the plurality of lenses is configured to refract light from the first light source of the plurality of first light sources to have a focal point in the transmissive area of the plurality of light transmissive areas based on the refraction characteristic and the distance to the light transmissive area.
A method of manufacturing a display, comprising:
- providing a plurality of first light sources, arranged in a first region;
- providing a plurality of lenses, arranged in a second region, over the first region;
- providing a plurality of opaque areas and a plurality of light transmissive areas, arranged in a third region, over the second region;
- wherein each light source of the plurality of first light sources is configured to direct light onto a lens of the plurality of lenses;
- wherein each lens of the plurality of lenses is configured to receive light from a first light source of the plurality of first light sources and to direct the light through a light transmissive area of the plurality of light transmissive areas;
- wherein each lens of the plurality of lenses is configured to receive light from a first light source of the plurality of first light sources and to direct the light through a light transmissive area of the plurality of light transmissive areas;
- wherein each lens of the plurality of lenses has a refraction characteristic and a distance to the light transmissive area of the plurality of light transmissive areas;
- and
- wherein the each lens of the plurality of lenses is configured to refract light from the first light source of the plurality of first light sources to have a focal point in the transmissive area of the plurality of light transmissive areas based on the refraction characteristic and the distance to the light transmissive area.
