Abstract
The present disclosure discloses methods, systems and modules for adjusting an interpupillary distance of a head-mounted 3D display. The method comprising: receiving a signal to start the head-mounted 3D display, after receiving the signal, scanning an interpupillary distance of a user wearing the head-mounted 3D display; setting centers of left and right eye images of a display screen based on the interpupillary distance of the user, wherein the centers of the left and right eye images are symmetrical about a physical midline of the display screen; and playing the same left and right eye guiding images by taking the centers of the left and right eye images as their centers, respectively, on the display screen to guide the user to adjust positions of left and right eye lenses. A head-mounted 3D display adopting the technical solution of this invention has an interpupillary distance adjustment function, making it suitable for different users.
