US Patent 11714283 Optical apparatus and near-eye display apparatus including the same

An optical apparatus and a near-eye display apparatus including the same are provided. The optical apparatus includes a display panel configured to form an image, a first polarization rotator configured to electrically control a light emitted from the display panel to have a first polarization state, a first ¼ wave plate configured to convert the first polarization state of a light transmitted from the first polarization rotator to a second polarization state, and an optical element group configured to display a first image having a first viewing angle and a second image having a second viewing angle that is greater than the first viewing angle based on the second polarization state of a light transmitted from the first ¼ wave plate.
