Abstract: 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.

Abstract: A display may have an array of pixels that forms an active display area for displaying images. An inactive border area of the display may have contact pads to which integrated circuits and flexible printed circuits may be attached. The contact pads may be free of organic planarization layers and may be formed from multiple stacked conductive layers. The inactive portion of the display may include electrostatic discharge protection structures associated with the pads, metal layers that form signal paths extending between the pads and the pixels, interlayer dielectric layers for protecting the metal layers that form the signal paths, polysilicon footer structures that help prevent undercutting of gate insulator material in the vicinity of the pads, and other pad and signal line structures.
