Abstract: A method of calibrating a touch sensing system includes connecting an impedance load to a touch sensing signal path in a gain adjustment mode, adjusting a gain of an amplifier that amplifies a signal input to the touch sensing signal path in the gain adjustment mode by evaluating an output signal of the amplifier, and disconnecting the impedance load from the touch sensing signal path after adjusting the amplifier gain.

Abstract: A touch sense panel includes a first set of individual sensing units for sensing a location along a first axis. The first set of individual sensing units includes a first plurality of strings of individual sensing units, each string including at least two of the individual sensing units of the first set. The at least two individual sensing units are electrically connected to each other and arranged in a direction perpendicular to the first axis. A first individual sensing unit of a first string of the first plurality of strings is electrically connected to a first individual sensing unit of a second string of the first plurality of strings, the second string adjacent to the first string, such that the first string and the second string form a single, first electrode.
