Abstract: The adjustment of stimulation signal amplitudes in capacitive touch sensor panels and/or styli to reduce power consumption while preserving satisfactory touch performance is disclosed, in particular in situations where the noise level is not significant and there is excess SNR margin. To accomplish this, one or more metrics can be measured, calculated or otherwise determined to use as a predictor of touch performance, and these metrics can be processed to determine the minimum stimulation voltage required to maintain acceptable touch performance.

Abstract: A touch sensitive device that detects the occurrence of an electrostatic discharge event on the device by analyzing one or more ESD sensors located in various locations on the touch sensitive device is provided. A touch controller can scan touch nodes on the touch sensitive device while simultaneously scanning one or more ESD sensors to detect if a possible ESD event has occurred during the acquisition of a touch image. If an ESD event has occurred during the acquisition of touch data, the touch controller can act to either ignore the data, or compensate the data to account for effects on the touch data caused by the ESD event.
