Abstract
A gate driver includes: a pull-up circuit configured to pull up a gate output signal to a high voltage in response to a signal at a first node of the pull-up circuit; a first pull-down circuit configured to pull down the gate output signal to a low voltage in response to a signal at a second node of the first pull-down circuit; a second pull-down circuit configured to pull down the gate output signal to the low voltage in response to a signal at a third node of the second pull-down circuit; a first selection circuit configured to activate the first pull-down circuit and deactivate the second pull-down circuit based on a first selection signal; and a second selection circuit configured to activate the second pull-down circuit and deactivate the first pull-down circuit based on a second selection signal.
