GATE DRIVER AND DISPLAY APPARATUS INCLUDING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18095097 titled 'GATE DRIVER AND DISPLAY APPARATUS INCLUDING THE SAME

Simplified Explanation

The abstract describes a gate driver, which is a circuit that controls the operation of a gate output signal.

• The gate driver includes a pull-up circuit that raises the gate output signal to a high voltage when a signal is received at a first node of the pull-up circuit.
• There is a first pull-down circuit that lowers the gate output signal to a low voltage when a signal is received at a second node of the circuit.
• Additionally, a second pull-down circuit is present, which also lowers the gate output signal to a low voltage when a signal is received at a third node of the circuit.
• A first selection circuit is included to activate the first pull-down circuit and deactivate the second pull-down circuit based on a first selection signal.
• Similarly, a second selection circuit is included to activate the second pull-down circuit and deactivate the first pull-down circuit based on a second selection signal.

Original Abstract Submitted

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.
