Abstract: A display may have a stretchable portion with hermetically sealed rigid pixel islands. A flexible interconnect region may be interposed between the hermetically sealed rigid pixel islands. The hermetically sealed rigid pixel islands may include organic light-emitting diode (OLED) pixels. A conductive cutting structure may have an undercut that causes a discontinuity in a conductive OLED layer to mitigate lateral leakage. The conductive cutting structure may also be electrically connected to a cathode for the OLED pixels and provide a cathode voltage to the cathode. First and second inorganic passivation layers may be formed over the OLED pixels. Multiple discrete portions of an organic inkjet printed layer may be interposed between the first and second inorganic passivation layers.

Abstract: An electronic device may include a substrate, an array of display pixels formed on the substrate, first conductive contacts on the substrate, second conductive contacts on the substrate, a flexible printed circuit that is attached to the first conductive contacts, a display driver integrated circuit that is attached to the second conductive contacts, and conductive traces that electrically connect the first conductive contacts to the second conductive contacts. A dielectric layer may cover at least the sidewalls of the conductive traces to protect the conductive traces from damage by an etchant. Subsequently, some or all of the dielectric layer may be removed to prevent damage caused by moisture ingress into the cladding layer.

Abstract: A display may include an active area with a first region and a second region. The first region may overlap an input-output component such as a camera and may have a higher transparency than the second region. The first region may have a lower pixel density than the second region. Signal lines that pass through the first region may have transparent portions that overlap the first region and opaque portions that overlap the second region. To mitigate artifacts caused by high resistance of the transparent portions of the signal lines, the signal lines may include supplemental opaque portions that are electrically connected in parallel to the transparent portions and that are routed through the second region around the first region.

Abstract: An electronic device may have a flexible display such as an organic light-emitting diode display. A strain sensing resistor may be formed on a bent tail portion of the flexible display to gather strain measurements. Resistance measurement circuitry in a display driver integrated circuit may make resistance measurements on the strain sensing resistor and a temperature compensation resistor to measure strain. A crack detection line may be formed from an elongated pair of traces that are coupled at their ends to form a loop. The crack detection line may run along a peripheral edge of the flexible display. Crack detection circuitry may monitor the resistance of the crack detection line to detect cracks. The crack detection circuitry may include switches that adjust the length of the crack detection line and thereby allow resistances to be measured for different segments of the line.

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 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 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.
