Cover structure, manufacturing method therefor, display device, and wearable device capable of displaying

A method for manufacturing a cover structure implemented in a display device, comprising:

• providing a substrate, the substrate having an optically transparent region and an edge region disposed around a periphery of the optically transparent region;
• forming a sunken step in the edge region at one side of the substrate, the sunken step being disposed around the periphery of the optically transparent region;
• and
• forming a first microstructure on a surface of the sunken step, the first microstructure comprising a plurality of first protrusions and a plurality of first recesses;
• wherein the optically transparent region is configured to enable a display module of the display device to display through the optically transparent region;
• wherein the method further comprises:
• forming a second microstructure on a surface of the optically transparent region, the surface is at one side of the cover away from the sunken step, and the second microstructure comprises a plurality of second protrusions and a plurality of second recesses;
• and
• wherein the method further comprises:
• disposing an optical film layer at one side of the second microstructure away from the sunken step.

A display device, comprising a cover structure, the cover structure comprising:

• a cover, the cover having an optically transparent region and an edge region disposed around a periphery of the optically transparent region, the edge region at one side of the cover having a sunken step, the sunken step being disposed around the periphery of the optically transparent region, a surface of the sunken step having a first microstructure, the first microstructure comprising a plurality of first protrusions and a plurality of first recesses;
• wherein the optically transparent region is configured to enable a display module of the display device to display through the optically transparent region;
• wherein a surface of the optically transparent region has a second microstructure, the surface is at one side of the cover away from the sunken step, and the second microstructure comprises a plurality of second protrusions and a plurality of second recesses;
• and
• wherein an optical film layer is disposed at one side of the second microstructure away from the sunken step.
