Tempered glass screen protector applied to a portable electronic device

A tempered glass screen protector applied to a portable electronic device, comprising:

• a substrate structure having a transparent portion and a non-planar decorative portion extended from three sides of the transparent portion, wherein a bottom surface of the transparent portion and a bottom surface of the non-planar decorative portion are connected with each other;
• a protection structure disposed on the bottom surface of the transparent portion, wherein the protection structure includes a first transparent adhesive layer disposed on the bottom surface of the transparent portion and a transparent protective layer disposed on the first transparent adhesive layer;
• and
• an adhesion structure disposed on the bottom surface of the non-planar decorative portion, wherein the adhesion structure includes a first adhesive layer disposed on the bottom surface of the non-planar decorative portion, a base layer disposed on the first adhesive layer, and a second adhesive layer disposed on the base layer;
• wherein the thickness of the protection structure is smaller than or substantially equal to the thickness of the adhesion structure, so that the height of the protection structure from the bottommost side of the protection structure to the bottom surface of the transparent portion is smaller than or substantially equal to the height of the adhesion structure from the bottommost side of the adhesion structure to the bottom surface of the non-planar decorative portion.

A tempered glass screen protector applied to a portable electronic device, comprising:

• a substrate structure having a transparent portion and a non-planar decorative portion extended from and around an outer perimeter surface of the transparent portion, wherein a bottom surface of the transparent portion and a bottom surface of the non-planar decorative portion are connected with each other;
• a protection structure disposed on the bottom surface of the transparent portion, wherein the protection structure includes a first transparent adhesive layer disposed on the bottom surface of the transparent portion and a transparent protective layer disposed on the first transparent adhesive layer;
• and
• an adhesion structure disposed on the bottom surface of the non-planar decorative portion, wherein the adhesion structure includes a first adhesive layer disposed on the bottom surface of the non-planar decorative portion, a base layer disposed on the first adhesive layer, and a second adhesive layer disposed on the base layer;
• wherein the thickness of the protection structure is smaller than or substantially equal to the thickness of the adhesion structure, so that the height of the protection structure from the bottommost side of the protection structure to the bottom surface of the transparent portion is smaller than or substantially equal to the height of the adhesion structure from the bottommost side of the adhesion structure to the bottom surface of the non-planar decorative portion.
