More Information
Summary:A touchscreen display includes one or more display drivers coupled to an active matrix display and one or more touch controllers coupled to one or more touch sensor conductors. The one or more display drivers are coupled to the active matrix display via active matrix conductive components. When enabled, the one or more display drivers is configured to transmit a first signal to the active matrix display in accordance with display operation. A touch sensor conductor includes one or more segments of the active matrix conductive components. When enabled, a touch controller of the one or more touch controllers is configured to transmit a second signal via the touch sensor conductor in accordance with touchscreen operation that is performed concurrently with the display operation.
