Abstract
A lamination structure of two-axis curvy touch panel includes a cover having a touch surface and an inner surface opposite to the touch surface, wherein the touch surface is a curved surface that protrudes from edge to center and has a long axis and a short axis. A transparent conduction module is flatly laminated to the inner surface of the cover to reduce a stress generated by laminating the transparent conduction module. A lamination area of said transparent conduction module is less than an area of the inner surface of the cover. The lamination structure of touch panel of the present invention applies to a two-axis curvy touch panel, wherein the cover is flatly laminated to the transparent conduction module to reduce stress values or improve stress concentration.
