Abstract
Methods, systems, and products illuminate display devices. Light in a waveguide is frustrated to illuminate an array of picture elements.
Claims20
A method, comprising:
- injecting light into a waveguide to create total internal reflectance;
- frustrating the total internal reflectance of the light at a surface of the waveguide;
- and
- withdrawing frustrated light from the surface of the waveguide onto an array of picture elements,
- wherein the frustrated light illuminates an image created by the array of picture elements.
2 more elements
An apparatus, comprising:
- an array of picture elements;
- a waveguide having total internal reflectance of light;
- and
- a frustrator for withdrawing frustrated light from the waveguide onto the array of picture elements,
- wherein the frustrated light illuminates an output produced by the array of picture elements.
2 more elements
An apparatus, comprising:
- a waveguide;
- a source for injecting light to create total internal reflectance in the waveguide;
- an array of picture elements for producing an output;
- and
- a frustrator for withdrawing frustrated light from the waveguide that illuminates the output.
