Claims26
A display device component comprising:
- an optical waveguide having a surface;
- a first material formed on a portion of said surface of said optical waveguide;
- a second material formed on said first material;
- and
- a third material formed on a portion of said surface of said optical waveguide, said portion of said surface of said optical waveguide having said first material formed thereon being distinct from said portion of said surface of said optical waveguide having said third material formed thereon;
- said second material being formed on said third material;
- said second material having light scattering properties;
- said third material being a non-white colored marking material having a color distinct from a color of said first material.

- a first material formed on a portion of said surface of said optical waveguide;
- a second material formed on a portion of said first material;
- a third material formed on a portion of said surface of said optical waveguide, said portion of said surface of said optical waveguide having said first material formed thereon being distinct from said portion of said surface of said optical waveguide having said third material formed thereon;
- said second material being formed on said third material;
- said second material having light scattering particles embedded therein;
- said third material being a non-white colored marking material having a color distinct from a color of said first material.
A process for making a display device component to enable image specific illumination of an image printed on an optical waveguide, comprising:
- (a) forming a first material on a portion of an optical waveguide having a surface;
- (b) forming a second material on the first material, the second material having light scattering properties;
- (c) forming a third material on a portion of the surface of the optical waveguide, the portion of the surface of the optical waveguide having the first material formed thereon being distinct from the portion of the surface of the optical waveguide having the third material formed thereon;
- and
- (d) forming the second material on the third material, the third material being a non-white colored marking material having a color distinct from a color of the first material.
