Abstract
Embodiments of a touch-sensitive display device are disclosed herein. According to a first aspect, a touch-sensitive display device comprises an electrode matrix including transmit electrodes and receive electrodes; a conductive plane; and a controller configured to cause a transmit electrode driver to drive the transmit electrodes in a mutual capacitance mode. The controller is configured to cause the transmit electrodes, the receive electrodes, and the conductive plane to be connected to a common charging voltage during charge periods of a self-capacitance mode; to, during discharge periods of the self-capacitance mode that alternate with the charge periods, cause the transmit electrodes, the receive electrodes, and the conductive plane to be connected to a common reference voltage; and to, during the discharge periods, cause the transmit electrodes and the receive electrodes to be coupled to receive circuitry configured to measure self-capacitance of the transmit electrodes and the receive electrodes.
