Abstract:
Disclosed are capacitive touchscreen or touch panel systems, devices and methods which increase the dynamic range of touches that may be detected on a capacitive touch screen or touch panel. Increased dynamic range is provided by employing automatic gain control methodologies and circuitry to process signals corresponding to individual mutual capacitance cells in a touch screen or touch panel.
