Method for Manufacturing a Light-Guide Optical Element

A method for manufacturing a light-guide optical element comprising:

• a coating step including forming at least one functional coating on a surface of a substrate, and cutting the substrate with the at least one functional coating to form at least one optical coating strip;
• a mounting step including placing at least one optical coating strip in a storage space of a first substrate, wherein the first substrate includes a plurality of first convex parts and a plurality of second convex parts, each of the first convex parts includes an inclined supporting surface, each of the second convex parts includes a stop surface facing the inclined supporting surface, and the stop surface is connected to the inclined supporting surface, the at least one optical coating strips is abutted against the inclined supporting surface, and the stop surface is used to stop the at least one optical coating strip;
• an assembling step including combining a second substrate corresponding to the first substrate with the first substrate, so that the at least one optical coating strip is positioned between the first substrate and the second substrate, forming a semi-finished product;
• and
• a cutting step including cutting the semi-finished product into at least one finished light-guide optical element, and the at least one finished light-guide optical element includes the at least one optical coating strip.
