STAGE CIRCUIT AND SCAN DRIVER USING THE SAME

摘要

A stage circuit includes an output part configured to supply a carry signal to a first output terminal and a scan signal to a second output terminal, in response to a voltage of a first node, a voltage of a second node, and a first clock signal being supplied to a first input terminal, a controller configured to control the voltage of the second node in response to the first clock signal being supplied to the first input terminal, a pull-up part configured to control the voltage of the first node in response to a carry signal of a previous stage being supplied to a second input terminal, and a pull-down part configured to control the voltage of the first node in response to the voltage of the second node and the carry signal of a next stage being supplied to a third input terminal.

主权项

1. A stage circuit comprising:
an output part configured to supply an i-th (where i is a natural number) carry signal to a first output terminal and an i-th scan signal to a second output terminal, in response to a voltage of a first node, a voltage of a second node, and a first clock signal being supplied to a first input terminal; a controller configured to control the voltage of the second node in response to the first clock signal being supplied to the first input terminal; a pull-up part configured to control the voltage of the first node in response to a carry signal of a previous stage being supplied to a second input terminal; and a pull-down part configured to control the voltage of the first node in response to the voltage of the second node and the carry signal of a next stage being supplied to a third input terminal, wherein the pull-down part comprises a first capacitor comprising a first electrode coupled to the first node and a second electrode coupled to the next stage.
