    Abstract: An electronic device may be provided with a display mounted in a housing. The display may include a color filter layer, a liquid crystal layer, and a thin-film transistor layer. The color filter layer may form the outermost layer of the display. A color filter layer substrate in the color filter layer may have opposing inner and outer surfaces. A layer of patterned metal on the inner surface may form metal alignment marks. The metal alignment marks may include alignment marks for color filter elements, alignment marks for a black matrix layer that is formed on top of the color filter elements, and post spacer alignment marks. The layer of patterned metal may also form structures such as logo structures that are visible on the outer surface in an inactive border region of the display.

    Abstract: An electronic device may be provided with an organic light-emitting diode display with minimized border regions. The border regions may be minimized by providing the display with bent edge portions having neutral plane adjustment features that facilitate bending of the bent edge portions while minimizing damage to the bent edge portions. The neutral plane adjustment features may include a modified backfilm layer of the display in which portions of the backfilm layer are removed in a bend region. A display device may include a substrate, a display panel on the substrate having display pixels, and peripheral circuitry proximate the display panel and configured to drive the display pixels. A portion of the periphery of the substrate may be bent substantially orthogonal to the display panel to reduce an apparent surface area of the display device. The bent portion may include an electrode for communication with the peripheral circuitry.

    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 electronic device may have a flexible display with portions that can be bent. The display may include an array of display pixels in an active area. Contact pads may be formed in an inactive area of the display. Display circuitry in the active area may exhibit a given stack height, whereas display circuitry in the inactive area may exhibit a stack height that is less than the given stack height. In particular, the contact pads may be formed directly on a multi-buffer layer that sits directly on a flexible display substrate. Passivation material may be selectively formed only at the edges of the contact pad on the multi-buffer layer. The multi-buffer layer may be formed at a distance from the edge of the flexible display substrate to minimize cracking in the multi-buffer layer.

    Abstract: A display may have an array of pixels. Each pixel may have a light-emitting diode that emits light under control of a drive transistor. The organic light-emitting diodes may have a common cathode layer, a common electron layer, individual red, green, and blue emissive layers, a common hole layer, and individual anodes. The hole layer may have a hole injection layer stacked with a hole transport layer. Pixel circuits for controlling the diodes may be formed from a layer of thin-film transistor circuitry on a substrate. A planarization layer may cover the thin-film transistor layer. Lateral leakage current between adjacent diodes can be blocked by shorting the common hole layer to a metal line such as a bias electrode that is separate from the anodes. The metal line may be laterally interposed between adjacent pixels and may be formed on the planarization layer or embedded within the planarization layer.
