Abstract: An electronic device may include a display having an array of display pixels on a substrate. The display pixels may be organic light-emitting diode display pixels or display pixels in a liquid crystal display. In an organic light-emitting diode display, hybrid thin-film transistor structures may be formed that include semiconducting oxide thin-film transistors, silicon thin-film transistors, and capacitor structures. The capacitor structures may overlap the semiconducting oxide thin-film transistors. Organic light-emitting diode display pixels may have combinations of oxide and silicon transistors. In a liquid crystal display, display driver circuitry may include silicon thin-film transistor circuitry and display pixels may be based on oxide thin-film transistors. A single layer or two different layers of gate metal may be used in forming silicon transistor gates and oxide transistor gates. A silicon transistor may have a gate that overlaps a floating gate structure.

Abstract: An organic light-emitting diode display may have an array of pixel circuits. Each pixel circuit may contain an organic light-emitting diode that emits light, a drive transistor that controls current flow through the diode, and additional transistors such as switching transistors for loading data into the pixel circuit and emission transistors for enabling and disabling current flow through the drive transistor and diode. Gate driver circuitry may produce emission control signals that control the emission transistors. Display driver circuitry may generate a start signal with a digitally controlled pulse width. The start signal may be applied to shift register circuitry in the gate driver circuitry. The pulse width of the start signal may be adjusted to adjust the luminance of the display.

Abstract: A display may have an array of pixels formed from organic light-emitting diodes and thin-film transistor circuitry. A planarization layer may be interposed between the thin-film transistor circuitry and the organic light-emitting diodes. To protect the organic light-emitting diodes from photoactive compounds that may be outgassed from the planarization layer, an inorganic barrier layer may be interposed between the planarization layer and the organic light-emitting diodes. The inorganic barrier layer may be formed on top of and/or below a pixel definition layer that defines light-emitting zones for the organic light-emitting diodes. In another suitable arrangement, the inorganic barrier layer may itself define light-emitting zones and may be used in place of a polymer-based pixel definition layer. The inorganic barrier layer may include trenches in which the emissive material of the light-emitting diodes is formed.

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.
