    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. The silicon transistors may be configured in a top gate arrangement. The oxide transistors may be configured in a top gate or a bottom gate arrangement. In one embodiment, source-drain contacts for the silicon and oxide transistors may be formed simultaneously. In another embodiment, the silicon and oxide thin-film transistor structures may be formed using at least three metal routing layers.

    Abstract: A display may have an array of pixels controlled by display driver circuitry. The pixels may have pixel circuits. In liquid crystal display configurations, each pixel circuit may have an electrode that applies electric fields to an associated portion of a liquid crystal layer. In organic light-emitting diode displays, each pixel circuit may have a drive transistor that applies current to an organic light-emitting diode in the pixel circuit. The pixel circuits and display driver circuitry may have thin-film transistor circuitry that includes transistor such as silicon transistors and semiconducting-oxide transistors. Semiconducting-oxide transistors and silicon transistors may be formed on a common substrate. Semiconducting-oxide transistors may have polysilicon layers with doped regions that serve as gates. Semiconducting-oxide channel regions overlap the gates. Transparent conductive oxide and metal may be used to form source-drain terminals that are coupled to opposing edges of the semiconducting oxide channel regions.

    Abstract: A display may have an array of light-emitting diode pixels or pixels containing portions of a liquid crystal layer to which electric fields are applied using electrodes. A pixel with a light-emitting diode may have a drive transistor coupled in series with the light-emitting diode. A storage capacitor may be coupled to a gate of the drive transistor. A pixel with a liquid crystal portion may have a storage capacitor coupled to a given one of the electrodes in that pixel. Switching circuitry in each pixel may be used to load data from a data line into the storage capacitor of the pixel. The switching circuitry may include a semiconducting-oxide transistor coupled to an associated data line and a series-connected silicon transistor that is coupled to the storage capacitor.
