Abstract
Provided are a positioning method and apparatus for a display screen in an optical module. The positioning method for the display screen in the optical module comprises the following steps: arranging light paths of an optical lens and image receiving device of a product coaxially; providing the display screen, and activating the display screen, wherein the display screen displays an image, and a light path formed by a light ray from the image passes through the optical lens; the image receiving device receives the light path passing through the optical lens in real time to obtain a virtual image; calculating a slope deviation of the display screen; calculating a distance deviation from the display screen to the optical lens; calculating a plane position deviation of the display screen; and calibrating a relative position of the display screen according to a calculation result.
