Abstract: A capacitive sensing device can include multiple capacitive sensors. A first device controller is operatively connected to a portion of the capacitive sensors, while a second device controller is operatively connected to another portion of capacitive sensors. A common node or shield can be connected between the first device controller and the second device controller. Charging and discharging events of selected drive lines in the capacitive sensing device and/or of the common node or shield can be synchronized to reduce undesirable effects such as noise and/or to prevent the charging events and the discharging events from overlapping with each other. One or more reference capacitive sensors can be shared by the multiple device controllers.

Abstract: A touch sensor panel is disclosed. The touch sensor panel includes a first layer including a plurality of electrodes of a first type that are coupled to respective traces and are configured to operate as touch sensing electrodes during a first time period. The touch sensor panel also includes a second layer including a plurality of electrodes of a second type overlapping with the respective traces of the electrodes of the first type. The electrodes of the second type are configured to operate as guard electrodes for the respective traces of the electrodes of the first type during the first time period and operate as touch sensing electrodes during a second time period.

Abstract: An integrated touchscreen can include light emitting diodes or organic light emitting diodes (LEDs/OLEDs), display chiplets and touch chiplets disposed in a visible area of the integrated touch screen. For example, the LEDs/OLEDs, display chiplets and touch chiplets can be placed on a substrate by a micro-transfer tool. The integrated touchscreen can also include electrodes disposed in the visible area of the integrated touch screen. The electrodes can be capable of providing display functionality via the one or more display chiplets during display operation (e.g., operating as cathode terminals of the LEDs during the display operation) and capable of providing touch functionality via the touch chiplets during touch operation (e.g., touch node electrodes can be formed from groups of the electrodes and sensed). In some examples, the touch node electrodes can be formed and coupled to touch chiplets via the display chiplets.

Abstract: A device configured to sense a touch on a surface of the device. The device includes a cover and a force-sensing structure disposed below the cover. The force-sensing structure may be positioned below a display and used in combination with other force-sensing elements to estimate the force of a touch on the cover of a device.

Abstract: A touch sensing system is disclosed. The touch sensing system includes a guard signal generation chip operating in a first power domain referenced to a first voltage, the guard signal generation chip configured to generate a guard signal. A touch sensing chip operates in a second power domain, different from the first power domain, referenced to the guard signal, the touch sensing chip configured to sense touch at one or more touch electrodes included in a touch sensor panel operating in the second power domain referenced to the guard signal, and the touch sensing chip a different chip than the guard signal generation chip. A voltage regulator is configured to selectively regulate a voltage of the guard signal at the touch sensing chip.

Abstract: A method of scanning a touch sensor panel while the touch sensor panel is coupled to a power adapter is disclosed. The power adapter can charge a battery of a device, but can also introduce or add noise during the process of charging the battery. To prevent adverse effects to the touch sensor panel, while the device is charging, the touch controller can time multiplex touch scan periods and inductive charging periods and can discard touch scans or touch images affected by the noise. Determining whether a touch scan is a bad touch scan can include performing a touch scan across the array of touch pixels and making a determination based on the scan profile. In some examples, the profile can be quantified using different metrics such as the shape, instantaneous slope of tail ends, a full-width half-maximum, and a monotonicity of the curve of the scan profile.
