Abstract
A scan driving circuit includes: a driving circuit configured to output a scan signal to an output terminal in response to clock signals and a carry signal; and a masking circuit configured to stop the driving circuit from outputting the scan signal in response to a masking signal and a signal indicating an operating state of the driving circuit.
Claims19
A scan driving circuit comprising:
- a plurality of driving stages configured to output a plurality of scan signals, respectively;
- and
- a masking circuit configured to electrically connect a carry node and a first voltage terminal,
- wherein each of the driving stages is configured to output a corresponding scan signal from among the plurality of scan signals in response to a carry signal from the carry node, and
