ABSTRACT:
An electro-optical display system includes a rear reflective heterogeneous polarizer having first and second regions. The first region transmits a first polarization state and reflects a second polarization state and the second region transmits the second polarization state and reflects the first polarization state. The system further includes a front heterogeneous polarizer having third and fourth regions. The third region is substantially aligned with and approximately the same size and shape as the first region and the fourth region is substantially aligned with and approximately the same size and shape as the second region.
