Abstract: A display may have contacts that mate with a flexible printed circuit. The contacts may be used in providing data and control signals to pixels. A metal layer may be patterned to form metal traces for signal lines that extend outwardly towards an edge of the display from the contacts. Delamination stopper structures may be formed along the periphery of the display to inhibit delamination between layers of material on the display. The delamination stopper structures may be formed from bent portions of the metal traces, a slot-shaped inorganic layer opening that runs perpendicular to the metal traces, and a segmented trench in an organic layer. A corrosion blocker structure may be formed by creating metal trace gaps in the metal traces that are each bridged by a pair of vias that are shorted together using transparent conductive material such as a pair of indium tin oxide layers.

Abstract: A display may have display driver circuitry. Signal routing lines may supply multiplexed signals from the display driver circuitry to demultiplexer circuitry. The demultiplexer circuitry may provide corresponding demultiplexed signals to the pixels over signal routing lines. The demultiplexer circuitry may have demultiplexer circuit blocks such as 1:N demultiplexer circuit blocks. Each of the demultiplexer circuit blocks may have the same area and layout. The demultiplexer circuit blocks may run across the width of the display. A first portion of the demultiplexer circuit blocks may extend in a straight line parallel to an edge of the active area. A second portion of the demultiplexer circuit blocks may be arranged in a staircase pattern that angles away from the first portion of demultiplexer circuit blocks.

Abstract: An electronic device may include a display such as a light-emitting diode display. The electronic device may be a head-mounted device that provides a virtual reality or augmented reality environment to a user. To reduce artifacts in the display, a display may be operable in both a normal scanning mode and a partial scanning mode. In the normal scanning mode, every row of the display may be scanned in each frame. In the partial scanning mode, only a subset of the rows of the display may be scanned in each frame. The display may have a higher refresh rate in the partial scanning mode than in the normal scanning mode. The gate driver circuitry may include a shift register that includes a plurality of register circuits. At least one register circuit may have a first input and a second input that is different than the first input.

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.
