crystal where it is aligned as the image requires and reflected back out. If the SXRD pixel has rotated the light, it then is not aligned with the post-PBS polarization and is allowed to pass. If the incoming light has not been rotated, then it is blocked by the post-PBS and reflected back into the source light path.

SXRD panel production

Unlike conventional LCoS panels, which are notoriously difficult to manufacture, the SXRD panel uses a production process that Sony has perfected in the company’s own, dedicated manufacturing facilities. This has enabled Sony to bring SXRD technology smoothly into production, while taking advantage of its many benefits.

Sony assembles the IMITO glass and silicon backplane prior to cutting the wafer into individual panels (singlation). In this way, Sony achieves three key features: a narrow cell gap, dust-free process and no LC gap spacers in the image area.
