Abstract: The attenuation of light per unit length in a waveguide as a result of active pixels (i.e., open pixels) may be corrected or mitigated by injecting apodized light into the waveguide. A light injection system and method is provided to enhance the luminous uniformity of the active pixels in a waveguide-based display. Embodiments of the present invention include a slab waveguide having a first edge and a second edge that intersect at a vertex, a first light source disposed along the first edge, and a second light source disposed along the second edge. The first light source, or the second light source, or both, comprises an apodized light source.
