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.
