  • Calibration for pressure effects on touch sensor panels
    Patent number: 9459738
    Abstract: A touch sensor panel which has been calibrated to be insensitive to effects from an external force applied to the panel is provided. Touch sense circuitry settings are adjusted during a calibration procedure so that when a force is exerted on the device, no change in the touch signal DC level is seen. In this way, the ability of the touch sensor panel to detect touch or proximity events is not affected by a force being applied to the panel.
