Abstract
A method of forming a curved touch surface is disclosed. According to an embodiment, the method includes depositing a touch sensor pattern on a flexible substrate; and curving the flexible substrate, using a chuck surface supporting the flexible substrate, to conform to a shape of a curved cover surface. Then, the curved flexible substrate can be laminated or otherwise adhered to the cover surface. The flexible substrate can be a glass substrate greater than 200 μm in thickness, and can be reduced to a desired thickness below 200 μm after the touch sensor pattern is deposited thereon. The flexible substrate can be curved by supporting the flexible substrate on the chuck surface such that the flexible substrate conforms to a shape of the chuck surface, or forcing the flexible substrate against the cover surface, such that the flexible substrate conforms to the shape of the curved cover surface.
