  • Publication number: 20240128274
    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: In one example, an electronic device includes a substrate including a substrate first side, a conductive structure, and a substrate sidewall on the substrate first side. The substrate sidewall forms a perimeter, the substrate first side within the perimeter defines a substrate base, and the substrate sidewall and the substrate base form a substrate cavity. An electronic component includes a component first side, a component second side, and a component lateral side. The electronic component is disposed over a first portion of the substrate base within the substrate cavity and is coupled to the conductive structure. An encapsulant encapsulates at least a portion of the component lateral side, and a lid is over at least a portion of the component first side. At least a portion of the component first side is devoid of the encapsulant. Other examples and related methods are also disclosed herein.

  • Patent number: 11940848
    Abstract: An electronic device display may have pixels formed from crystalline semiconductor light-emitting diode dies, organic light-emitting diodes, or other pixel structures. The pixels may be formed on a display panel substrate. A display panel may extend continuously across the display or multiple display panels may be tiled in two dimensions to cover a larger display area. Interconnect substrates may have outwardly facing contacts that are electrically shorted to corresponding inwardly facing contacts such as inwardly facing metal pillars associated with the display panels. The interconnect substrates may be supported by glass layers. Integrated circuits may be embedded in the display panels and/or in the interconnect substrates. A display may have an active area with pixels that includes non-spline pixels in a non-spline display portion located above a straight edge of the display and spline pixel in a spline display portion located above a curved edge of the display.
