Abstract
A display module and manufacturing method thereof. The display module comprises a display screen, a first absorption polarizer, a first quarter wave plate, an optical lens component, and a convex lens component in sequence from a display side to a viewing side. The optical lens component and the convex lens component are optically coaxial. The convex lens component comprises a convex lens, a second absorption polarizer, and an optical integrated element, which are laminated in sequence from the viewing side to the display side. The optical integrated element comprises a second quarter wave plate and, on one side surface of the optical integrated element, a coated reflective polarizing film or a nano-imprinted metal grating. The reflective polarizing film or the metal grating is attached to the second absorption polarizer.
