An electro-optical display includes a light source and a Polarization Separation Element (''PSE'') coupled to the light source. The PSE generates a first output having a first polarization state and a second output having a second polarization state. The display further includes a Hetero Polar Light Guide (''HPLG'') that includes a first region optically isolated from a second region and coupled to the PSE. The first output of the PSE is directed into the first region and the second output of the PSE is directed into the second region, and the first region and second region output light in substantially the same direction.
