  • Patent number: 12231613
    Abstract: An object displaying system includes a right light signal generator, a left light signal generator, a right combiner, and a left combiner. The right light signal generator generates right light signals for an object. The right combiner receives and redirects the right light signals towards one retina of a viewer to display multiple right pixels of the object. The left light signal generator generates leftght signals for the object. The left combiner receives and redirects the left light signals towards the other retina of the viewer to display multiple left pixels of the object. A first redirected right light signal and a corresponding first redirected left light signal are perceived by the viewer to display a first virtual binocular pixel of the object with a first depth that is related to a first angle between the first redirected right light signal and the corresponding first redirected left light signal.
