In the SXRD panel, light from the lamp enters through the glass substrate at the top, passes through the Liquid Crystal layer, reflects off the mirrored surface of the Silicon backplane, then passes out through the Liquid Crystal, toward the screen.

Output

Simplified view of Sony's optical engine. It performs polarization with a series of Polarized Beam Splitters external to the SXRD panels themselves.

Where H-LCD panels include all three of these elements, SXRD panels include only one: the liquid crystal. Polarization is handled by external Polarized Beam Splitters (PBS's). Before light reaches the SXRD panel, it reflects off the corresponding pre-PBS. This pre-polarized light passes through the SXRD liquid
