Abstract
Disclosed herein are various embodiments of circuits and methods for capacitively coupling touchscreen electrode terminals to terminals of a flex circuit, printed circuit or printed circuit board, without physically attaching the touchscreen electrode terminals to the flex circuit, printed circuit or printed circuit board terminals by means of conventional electrical connection bonding materials or agents such as anisotropic conductive film or solder. The flex circuit, printed circuit or printed circuit board terminals are spaced apart from, or placed in physical contact with, corresponding ones of the touchscreen electrode terminals, but are not soldered or otherwise physically attached to the touchscreen electrode terminals by conventional electrical connection bonding materials or agents such as anisotropic conductive film or solder. The flex circuit, printed circuit or printed circuit board terminals are positioned with respect to the touchscreen electrode terminals such that the flex circuit, printed circuit or printed circuit board terminals are spaced part from, or in physical contact with, the touchscreen electrode terminals by gaps ranging between about 0.0 mm and about 1 …
