    Abstract: Display driver circuitry may load data into an array of pixels via data lines. The display driver circuitry may supply control signals including scan signals to the pixels via control lines. Each pixel may have transistors and capacitor circuitry for controlling the emission of light from a light-emitting diode. A drive transistor may be coupled in series with the light-emitting diode to control the amount of current flowing through the light-emitting diode. The drive transistor may have a drive transistor gate terminal that is coupled to one of the source-drain terminals of a switching transistor. The switching transistor may have a switching transistor gate terminal that receives the scan signal. When transitioning prior to an emission phase of operation, the scan signal may have a two-step transition profile or other shape that enhances display performance by reducing dynamic effects in the switching transistor.

Each display pixel may also have control transistors for compensation and programming operations. Each display pixel may have six thin-film transistors and one capacitor.
