    Abstract: An electronic device display may have an active area with pixels. An optical sensor may be formed under a sensor region in the active area. During operation, ambient light and/or other light associated with the optical sensor may pass through the sensor region. To ensure that the light for the optical sensor can pass through the display, the display may have one or more layers with sensor openings such as a metal layer and a pressure sensitive adhesive layer that attaches the metal layer to the pixels of the display. To help minimize visibility of the openings in the sensor region, the pressure sensitive adhesive layer may be configured to have a reflectivity that matches the appearance of the display in the sensor region to surrounding areas. Undesired light output uniformity can be reduced by ensuring that the substrate material in the display has a low light absorption coefficient.

    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: A display may have an array of pixels. Display driver circuitry may supply data and control signals to the pixels. Each pixel may have seven transistors, a capacitor, and a light-emitting diode such as an organic light-emitting diode. The seven transistors may receive control signals using horizontal control lines. Each pixel may have first and second emission enable transistors that are coupled in series with a drive transistor and the light-emitting diode of that pixel. The first and second emission enable transistors may be coupled to a common control line or may be separately controlled so that on-bias stress can be effectively applied to the drive transistor. The display driver circuitry may have gate driver circuits that provide different gate line signals to different rows of pixels within the display. Different rows may also have different gate driver strengths and different supplemental gate line loading structures.

    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: Thin-film transistor circuitry for a display may include conductive layers such as transparent conductive layers and metal layers and may include dielectric layers. The dielectric layers may include buffer layers, interlayer dielectric, gate insulator, and organic planarization layers. The organic planarization layers may be patterned photolithographically to form vias, trenches, and other structures. Trenches may be formed by removing the planarization layer in a strip. When planarization material is removed for forming a trench or other structure, a step is formed in the planarization material. Metal lines such as data lines and other signal lines may cross steps in the planarization material. To prevent shorts between lines, a step may have protrusions that help eliminate metal etch residue. Vias may be reduced in depth by forming metal bumps and dielectric bumps under the vias and by forming other via structures.
