  • 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.

  • Patent number: 8348480
    Abstract: An adjustable structure for lamp stand, in which a swivel mount is fitted to the upper portion of a base, thereby enabling ends of a first bar support and a telescopic link to be pin connected to the swivel mount, while the other ends are pin connected to a second bar support. A lamp swivel component is disposed on the end of the second bar support. Accordingly, relative positions between the first bar support, the second bar support and the telescopic link can be freely adjusted, while still providing stable support to the structure.
