Abstract: A curved touch module structure and a method for laminating the same, which are the theremoplastic technologies, are used to solve the problem with wrinkles at stress-accumulated positions easily caused by a laminated material during a process of laminating a curved surface. The internal curved surface of an appearance-protecting layer has a planar structure whose position corresponds to the bonding area of a touch element layer. When the touch element layer is theremoplastically laminated to the curved surface of the appearance-protecting layer, the first bonding pads of the bonding area are formed on the planar structure. As a result, when a rear-end process for hot pressing and bonding is performed, a bonding platform needs to be designed according to the shape and curvature of products without modifying the other existing elements, thereby increasing the fabrication yield and reducing the production cost.

Abstract: A method for laminating and aligning an irregular-shape material is disclosed. Since the existing laminating material has an irregular shape, there is a problem with disabling alignment in a lamination process. Thus, the irregular shape of the laminating material is used to form a straight line correlated with a tangent line to the shape, and the straight line is used as the shape-aligned feature of the laminating material. Besides, the definition of an alignment relationship between the laminating material and a laminated object is established to adjust a lamination tolerance and prevent the laminating material from overhanging over the laminated object, thereby satisfying consumers' aesthetic needs for the appearance of products.
