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 first complementary inverter configured to receive a carry in signal, a second complementary inverter having an input coupled to the first complementary inverter and having an output at which a carry out signal is produced, and an output buffer subcircuit coupled to the input of the second complementary inverter. The output buffer subcircuit can include a first output buffer transistor coupled in series with a second output buffer transistor. The first complementary inverter can receive the carry in signal through a transmission gate that is controlled by two shift register clock signals.
