Abstract: An apparatus of one embodiment includes a sensor and a controller. The sensor has first and second electrodes separated by an insulator. The controller includes measurement circuitry, a processor, and a memory comprising logic. The logic is operable to disconnect the second electrode from the measurement circuitry, induce a current on the second electrode by applying voltage to the first electrode, apply charge to the second electrode, connect the second electrode to the measurement circuitry after applying the charge to the second electrode, and determine a capacitance value associated with the second electrode.

Abstract: An apparatus includes a display stack and a controller. The display stack includes a display and a ground layer. The ground layer includes a plurality of columns. Each column of the plurality of columns includes a plurality of nodes. The controller provides voltages to a first plurality of nodes of a first column of the plurality of columns of the ground layer such that a sum of the voltages of the first plurality of nodes of the first column is less than or equal to two millivolts. The controller also measures values at a second plurality of nodes of a second column of the plurality of columns. The values at the second plurality of nodes indicates an amount of charge transferred from the first plurality of nodes to the second plurality of nodes.

Abstract: In certain embodiments, an apparatus includes a display stack and a controller. The display stack includes a display and a ground layer for generating an image for the display. The ground layer includes a plurality of columns. Each column of the plurality of columns includes a plurality of nodes. The controller provides voltages to a first plurality of nodes, respectively, of a first column of the plurality of columns of the ground layer such that a sum of the respective voltages of the first plurality of nodes of the first column is substantially zero. The controller also measures, to determine whether a touch event occurred, respective values at a second plurality of nodes of a second column of the plurality of columns. The respective values at the second plurality of nodes indicate an amount of charge transferred from the first plurality of nodes to the second plurality of nodes.

Abstract: In an embodiment, a touch-sensitive device includes a controller, a shield sensor, a plurality of first electrodes, and a plurality of second electrodes. The plurality of first electrodes spans a first direction and the plurality of second electrodes spans a second direction that is different than the first direction. The controller electrically couples the plurality of first electrodes to the shield sensor. The shield sensor charges the plurality of first electrodes to cause substantially equal voltages to be present on the plurality of first electrodes and the plurality of second electrodes.

Abstract: In one embodiment, an apparatus includes a sensor and a controller having a processor and a memory. The memory includes logic operable, when executed by the processor, to connect each electrode of a first subset of electrodes of the sensor and determine a first value associated with the first subset of electrodes. Based at least on the first value, the logic is further operable to alter the first subset of electrodes to a second subset of electrodes and connect, in response to determining to alter the first subset of electrodes to the second subset of electrodes, each electrode of the second subset of electrodes of the sensor.
