Abstract
A pixel structure, displays, and display panels comprising a plurality of pixel structures, are provided. The pixel structure comprising: a Continuous Resonant Trap Refractor waveguide having a tapered core with an aperture for emitting the light and a narrower end or tip, the tapered core having cladding disposed thereabout, the core and the cladding both being transmissive of light; and a plurality of light sources disposed for coupling light into the core via the cladding. Preferably the light sources are disposed within layers of substrate, which may form lateral waveguides. An optional plurality of light sources disposed at an angle offers emitting a simultaneous plurality of images, each having a different polarization, for 3D viewing, and other desired emissions at varying polarizations.
