Abstract: A display may include an array of pixels that receive control signals from a chain of gate drivers. Each gate driver may include a mix of silicon transistors, one or more semiconducting oxide transistors, and one or more capacitors. The semiconducting oxide transistors can each have a back gate terminal shorted to one of its source-drain terminals, shorted to its front gate terminal, or configured to receive a bias voltage. Configured in this way, the gate driver circuit can exhibit less threshold voltage drift and thus improved device reliability over time.

Abstract: A number of unit cells of a digital-to-analog converter (DAC) may be simultaneously activated to generate an analog signal. However, while each unit cell may be generally the same, there may be variations such as non-linearity or noise in the analog output depending on which unit cells are activated for a given digital signal value. For example, as additional unit cells are activated for increased values of the analog signal, the fill order in which the unit cells are activated may affect the linearity/noise of the DAC. The decision units may be programmable to select which branches of the fractal DAC to activate, changing the fill order based on a fill-selection signal. The fill order may be set by a fill controller via the fill-selection signal to account for manufacturing variations, gradients in the supply voltage, output line routing, and/or environmental factors such as temperature.
