Display module, display apparatus and method for manufacturing the same

A method for manufacturing a display apparatus, the manufacturing method comprising:

• providing a display panel, the display panel including a functional device arrangement region and a main display region surrounding the functional device arrangement region;
• forming a first light-shielding pattern on a light-exit side of the display panel, an orthogonal projection of the first light-shielding pattern on the display panel substantially coinciding with the functional device arrangement region of the display panel;
• providing a circular polarizer, an adhesive layer and a first protective layer sequentially on the light-exit side of the display panel on which the first light-shielding pattern has been formed;
• punching a hole in the functional device arrangement region of the display panel to form an initial hole, the initial hole penetrating the display panel, the first light-shielding pattern, the circular polarizer, the adhesive layer and the first protective layer, wherein the first light-shielding pattern is located on a side of the circular polarizer proximate to the display panel, and the circular polarizer is directly connected to the display panel and the first light-shielding pattern;
• etching a side wall of the initial hole so that the side wall of the initial hole is of one of a step-shaped and a protrusion-depression structure, so as to form a mounting hole;
• and
• forming a second light-shielding pattern, the second light-shielding pattern covering at least a side wall of the mounting hole and a portion of a surface of the first light-shielding pattern away from the display panel, the first light-shielding pattern being connected to the second light-shielding pattern.

A display apparatus, comprising:

• a display module having a functional device arrangement region and a main display region surrounding the functional device arrangement region;
• wherein the functional device arrangement region is provided with a mounting hole therein, and the functional device arrangement region includes a reserved region surrounding the mounting hole;
• a side wall of the mounting hole is of one of a step-shaped and a protrusion-depression structure;
• the display module includes:
• a display panel;
• a first light-shielding pattern disposed on a light-exit side of the display panel, an orthogonal projection of the first light-shielding pattern on the display panel substantially coinciding with the reserved region of the display panel;
• an adhesive layer disposed on a side of the first light-shielding pattern away from the display panel, the mounting hole penetrating the display panel, the first light-shielding pattern and the adhesive layer;
• a second light-shielding pattern covering at least the side wall of the mounting hole and a portion of a surface of the first light-shielding pattern away from the display panel, the first light-shielding pattern being connected to the second light-shielding pattern;
• and
• a circular polarizer disposed between the display panel and the adhesive layer, the first light-shielding pattern being located on a side of the circular polarizer proximate to the display panel, the circular polarizer being directly connected to the display panel and the first light-shielding pattern, and the mounting hole further penetrating the circular polarizer;
• and
• a cover plate disposed on a side of the adhesive layer away from the display panel.
