Apple Fine-Tunes Head-Mounted Display Invention with an Emphasis on a Catadioptric Optical System & more
Today the US Patent & Trademark Office published a continuation patent from Apple that relates to optical systems and, more particularly, to optical systems for head-mounted displays. Today's patent is not a new invention application but rather a continuation patent wherein Apple is updating and/or adding specific technology, features and/or methods to their invention that they want to legally protect.
Apple's patent claims found in their February 2019 granted patent 10,203,489 emphasized linear and reflective polarizers. In today's continuation patent Apple emphasizes or adds emphasis in their patent claims on a catadioptric optical system; cylindrical surfaces; and a polarizer that is thermoformed to the aspherical shape of the fourth surface.
Apple's patent FIGS. 8 and 9 above are respectively top and side views of lens elements with cylindrical surfaces.
Apple's continuation patent 20190146198 that was published today by the U.S. Patent Office was originally filed back in Q4 2018. Patently Apple originally covered this as a patent application back in 2018. Review our report for more information and patent figures associated with this invention, here.
Considering that this is a continuation patent, the timing of such a product to market is unknown at this time.
