    Abstract: A method is provided for fabricating a thin-film transistor (TFT). The method includes forming a semiconductor layer over a gate insulator that covers a gate electrode, and depositing an insulator layer over the semiconductor layer, as well as etching the insulator layer to form a patterned etch-stop without losing the gate insulator. The method also includes forming a source electrode and a drain electrode over the semiconductor layer and the patterned etch-stop. The method further includes removing a portion of the semiconductor layer beyond the source electrode and the drain electrode such that a remaining portion of the semiconductor layer covers the gate insulator in a first overlapping area of the source electrode and the gate electrode and a second overlapping area of the drain electrode and gate electrode.

    Abstract: An electronic device may have a flexible display. The display may have portions that are bent along a bend axis. The display may have display circuitry such as an array of display pixels in an active area and signal lines, thin-film transistor support circuitry and other display circuitry in an inactive area of the display surrounding the active area. The display circuitry may be formed on a substrate such as a flexible polymer substrate. The flexible polymer substrate may be formed by depositing polymer on a support structure that has raised portions.The raised portions may create locally thinned regions in the flexible polymer substrate. The reduced thickness of the flexible polymer substrate in the thinned regions may help ensure that a neutral stress plane that is associated with bending the display along the bend axis is aligned with the display circuitry, thereby minimizing stress in the display circuitry.

    Abstract: An electronic device may include a display. The display may include display driver circuitry that is configured to provide image data to columns of pixels and gate driver circuitry that is configured to provide control signals to rows of pixels. The display may be operable at a native refresh rate that is equal to the highest refresh rate at which the display has full resolution. The display may also be operable in a high refresh rate mode with a high refresh rate that is twice (or some other scaling factor greater than) the native refresh rate. To enable operation at the high refresh rate mode, vertical resolution of the display may be sacrificed. In other words, rows of pixels may be grouped together into effective rows that are then scanned in sequence. The gate driver circuitry may be formed as thin-film transistor circuitry or from gate driver integrated circuits.

    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.
