Abstract: A touch sensitive device that detects the occurrence of an electrostatic discharge event on the device by analyzing an acquired touch image for characteristics associated with the occurrence of an ESD event is provided. An acquired touch image is analyzed for characteristics that differentiate it from a touch image generated by a user input and are correlated with an expected touch image generated by an ESD event.

Abstract: A touch sensor panel. In some examples, a first touch pixel can be coupled to a first sense connection, and a second touch pixel can be coupled to a second sense connection. In some examples, a first portion of the first sense connection can be disposed in a first region of the touch sensor panel, a second portion of the second sense connection can be disposed in the first region, and a third portion of the second sense connection can be disposed in a second region of the touch sensor panel. In some examples, a width of the third portion of the second sense connection can be larger than a width of the second portion of the second sense connection.

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.

Abstract: A touch input device configured to detect a touch input event and determine if the touch input event is caused by a floating object is provided. The touch input device includes one or more electrodes that scanned with a set of stimulation signals to first detect the presence of a touch event and then scanned with subsequent sets of stimulation signals in order to determine if the touch event is from a grounded object, a poorly grounded object, or a floating object.

Abstract: A touch controller is disclosed. In some examples, the touch controller can include sense circuitry configured to be coupled to a first touch pixel and a second touch pixel on a touch sensor panel. In some examples, the sense circuitry can be configured to drive and sense the first touch pixel during a first time period while coupling the second touch pixel to a reference voltage. In some examples, the sense circuitry can be configured to drive and sense the second touch pixel during a second time period while coupling the first touch pixel to the reference voltage. In some examples, the reference voltage can be a system ground of the touch controller. In some examples, the sense circuitry can be configured to drive and sense pluralities of touch pixels in a similar manner.

Abstract: Touch scan modes for touch sensitive devices during device charge is disclosed. To prevent adverse effects to the touch sensor panel due to inductive noise while the device is charging, the touch controller can switch to a touch scan mode (i.e., power charging touch mode) that can cancel or reduce noise from the touch scan or touch image. Power charging touch modes can include low noise frequency selection, increased number of touch samples employed to calculate an average, and simultaneous sampling. In some examples, a power charging touch mode can be different from a normal touch scan mode (i.e., a touch scan mode when the device is not charging). With the one or more power charging touch modes, false touch readings, erroneous touch location identification, and/or undetected touches can be eliminated or reduced.
