  • 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: 11946569
    Abstract: An actuating and sensing module is disclosed and includes a bottom plate, a gas pressure sensor, a thin gas transportation device and a cover plate. The bottom plate includes a pressure relief orifice, a discharging orifice and a communication orifice. The gas pressure sensor is disposed on the bottom plate and seals the communication orifice. The thin gas transportation device is disposed on the bottom plate and seals the pressure relief orifice and the discharging orifice. The cover plate is disposed on the bottom plate and covers the gas pressure sensor and the thin gas-transportation device. The cover plate includes an intake orifice. The thin gas transportation device is driven to inhale gas through the intake orifice, the gas is then discharged through the discharging orifice by the thin gas transportation device, and a pressure change of the gas is sensed by the gas pressure sensor.
