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 compliant material, such as a conductive foam, is positioned in the dielectric or capacitive gap between drive and sense electrodes and/or other conductive elements of a capacitive and/or other force sensor, such as a TFT or other display element and a sensor assembly. The compliant material prevents damage by preventing and/or cushioning contact. The compliant material may be conductive. By being conductive and being positioned between the electrodes while still being separated from one or more of the electrodes, the compliant material also shortens the effective electrical distance between the electrodes. As a result, the force sensor may be more sensitive than would otherwise be possible while being less vulnerable to damage.

Abstract: Touch sensor panel configurations for reducing wobble error for a stylus translating on a surface over and between electrodes of the touch sensor panel are disclosed. In some examples, electrodes with more linear signal profiles are correlated with lower wobble error. In some examples, diffusing elements formed of floating segments of conductive materials can diffuse signal from a stylus to a plurality of electrodes, thus, making the signal profiles associated with the electrodes more linear. In addition, diffusing elements can be configured to improve the optical uniformity of the touch sensor panel. In some examples, the diffusing elements can be formed on the same layer as floating dummy pixels and resemble a plurality of merged floating dummy pixels.

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.
