Display device with mechanically adjustable optical combiner

Abstract:

An optical system may include a head-mounted support structure configured to receive a removable portable electronic device with a display to form a head-mounted device. A head-mounted device may also be formed by incorporating a non-removable display into a head-mounted support structure. An optical combiner may be coupled to the head-mounted support structure. During operation of the head-mounted device, real-world image light passes through the optical combiner to eye boxes in which the eyes of a user are located. Display image light from the display reflects from a curved partially reflective surface of the optical combiner towards the eye boxes. To make optical adjustments such as virtual image distance adjustments, one or more actuators may be used to mechanically adjust the optical combiner.
