1. A display material comprising:

  • a first waveguide segment traversing at least a portion of said material;

    a first controllable optical switch disposed along said first waveguide segment, and disposed further to redirect optical energy out of said first waveguide segment in dependence upon a first control signal; and

    a first upconversion phosphor disposed to receive optical energy from said first optical switch, said phosphor re-radiating optical energy out of said material in response to optical energy excitation.
