Prior Art Detail
Summary / Description
| Summary / Description | "A color display system which includes a plurality of light emitting polymer (LEP) optical fibers each formed as plurality of light-emitting segments for emitting a specific color by using a special light emitting polymer. The light emitting segments are arranged as a two-dimensional array with each of the light emitting segments controlled to turn on and off for presenting a color image by turning on a plurality of the light emitting segments." |

Excerpt
Excerpt From claim one - A color display system comprising: a plurality of light emitting polymer (LEP) optical fibers each formed as plurality of light-emitting segments for emitting a specific color by using a special light emitting polymer; said light emitting segments arranged as a two-dimensional array with each of said light emitting segments controlled to turn on and off for presenting a color image by turning on a plurality of said light emitting segments; each of said light emitting segments comprising an indium/tin oxide (ITO) layer segment covering said LEP optical fiber wherein said each of said ITO segments is connected to an ITO control voltage for turning on and off said light emitting segment. each of said LEP optical fiber is supported on an glass fiber core carrier covered by a metal electrode layer, and said metal electric layer is further covered by a light emitting polymer (LEP) layer; and said ITO layer segments coated over said LEP layer whereby a voltage applied between said metal electrode layer and a selected ITO layer segment turning on a selected light emitting segment covered by said selected ITO layer segment for emitting a light from said LEP layer to project outwardly through said selected ITO layer segment. |

Claims
1
An optical display comprising:
a plurality of strands arranged in spaced apart relationship;
each strand having a plurality of waveguides with each guide having an output at a different position along the length of the respective strand;
each waveguide having an input end; and
a light driver supplying light to the input end of each waveguide so light can propagate along the waveguide and exit at the outputs.
| Relevance | Both optical displays using strands/waveguides to output a colour element. |
