1. A touchscreen display comprising:
one or more display drivers operably coupled to an active matrix display via a plurality of active matrix conductive components, wherein, when enabled, a display driver of the one or more display drivers is configured to transmit a first signal to at least one of the plurality of active matrix conductive components in accordance with display operation, wherein:
the plurality of active matrix conductive components includes a common ground plane that is segmented into a plurality of segments including a plurality of inner portions and a plurality of outer portions; and
a touch sensor conductor includes an outer portion of the plurality of outer portions; and
one or more touch controllers operably coupled to a plurality of touch sensor conductors including the touch sensor conductor, wherein, when enabled, the one or more touch controllers configured to transmit a second signal to the touch sensor conductor in accordance with touchscreen operation that is performed concurrently with the display operation also using active matrix conductive components of the touch sensor conductor.
