Display with touch sensor circuitry
A display may have an array of pixels. A transparent conductive layer may serve as a common voltage electrode layer and may distribute a common voltage to each of the pixels. Metal layers may be used to form routing structures. One of the metal layers may be patterned to form gate lines that distribute control signals to thin-film transistors in the pixels. Touch sensor circuitry may be coupled to horizontal and vertical capacitive touch sensor electrodes formed from the transparent conductive layer. A touch sensor signal border routing path in an inactive area of the display may have openings that run parallel to the gate lines and that each overlap one of the gate lines to reduce capacitive coupling between the gate lines and the touch sensor signal border routing path.
