    Abstract: A display may have thin-film transistor (TFT) circuitry on a substrate. An array of organic light-emitting diodes may be formed on the thin-film transistor circuitry. The display may include inorganic brittle layers and organic and metal layers that are ductile and mechanically robust. To help prevent propagation of cracks and other defects along the edge of the display, the display may be provided with crack stop structures and crack detection circuitry. The crack detection circuitry may include one or more loops that are formed along the periphery of the display. The crack stop structures may include TFT/OLED structures formed in a staggered configuration. At least some of the brittle layers can be removed from the panel edge. An additional adhesion layer may also be formed directly on the substrate to help prevent inorganic layers from debonding from the surface of the substrate.

    Abstract: A display having thin-film transistor (TFT) structures may be used to display images within an active area of the display, which is surrounded by an inactive border area. In order to reduce the inactive area, a TFT passivation layer may be used to help protect conductive routing lines at the outer edge of the border so that encapsulation layers need not be formed all the way to the edge. At least some of the conductive routing lines in the inactive area may be stacked or coupled in parallel to help reduce border width. The TFT passivation layer may also cover the lateral edges of the routing lines to help prevent corrosion during an anode etch. The encapsulation layers may also be formed in a bent portion of the display substrate to help adjust the neutral stress plane such that metal traces formed in the bent portion do not crack.

    Abstract: An electronic device may have a hinge that allows the device to be flexed about a bend axis. A display may span the bend axis. To protect display elements such as pixel circuitry from excessive mechanical stress, the display may include one or more structural protective layers. A structural layer may be incorporated into the display stack as a supportive backing behind the pixel circuitry and/or as a protective cover over the pixel circuitry. The structural layer may include rigid portions and flexible portions. The flexible portions may contain flexible material that separates and adjoins adjacent rigid structures or that fills grooves between adjacent rigid portions. The rigid portions may be formed from thin sheets of glass or other transparent materials. The flexible material in the structural layer may be an elastomeric material having a refractive index that matches that of the glass sheets in the structural layer.
