3D (three dimensional) cylinder mirror film with alignment targets

The invention provides a 3D (three dimensional) cylinder mirror film with alignment targets. The 3D cylinder mirror film with the alignment targets comprises an upper cementing layer which is a transparent double faced adhesive tape, an upper cylinder mirror layer which is a transparent upper cylinder mirror, a lower cylinder mirror layer which is a transparent lower cylinder mirror, a lower substrate layer which is a transparent substrate, a lower cementing layer which is another transparent double faced adhesive tape, and a plurality of the alignment targets which are arranged on appropriate positions of the lower substrate layer or the lower cylinder mirror layer and of two dimensional graph structure, and have optical outline strengthening features. The 3D cylinder mirror film with the alignment targets provides a double face gluing function during the assembly and gluing process among the 3D cylinder mirror film with the alignment targets, a displayer screen and a touch panel, and additionally can provide alignment target images high in definition and high in contrast ratio for an optical camera system used in assembly alignment, substantially improves assembly alignment accuracy between the 3D cylinder mirror film and the displayer screen, and achieves the purpose of providing the best 3D image quality.
