Reducing touch node electrode coupling

Abstract:

A touch screen is disclosed. The touch screen comprises a first touch node electrode associated with a first display pixel, the first display pixel coupled to a first gate line. The touch screen also comprises a second touch node electrode associated with a second display pixel, the second display pixel coupled to a second gate line. The touch screen also comprises a voltage source coupled to a first gate line routing and a second gate line routing, wherein the first gate line is coupled to the first gate line routing, and the second gate line is coupled to the second gate line routing.
