Abstract
A system is disclosed. The system can comprise dynamic drive circuitry configured to drive a plurality of electrodes on a touch screen. The system can also comprise a switching circuit configured to selectively couple the dynamic drive circuitry to one or more of the plurality of electrodes. The system can also comprise a display circuitry configured to selectively update a plurality of display pixels on the touch screen. The dynamic drive circuitry can be configured to set its output based on which of the plurality of electrodes are selectively coupled to the first drive circuitry and which of the display pixels are updated by the display circuitry.
