Abstract:
A driving circuit includes: a plurality of scan stages each corresponds to a plurality of scan lines, receives clock signals and a carry signal, and outputs a scan signal; and a plurality of masking circuits corresponding to some scan stages, respectively, among the scan stages. each masking circuit outputs one of the scan signal output from a corresponding scan stage and a first voltage as a masking carry signal in response to a masking signal. A j-th scan stage receives a scan signal output from a (j−a)th scan stage as the carry signal when the (j−a)th scan stage is not one of the some first scan stages, and the masking carry signal output from a masking circuit corresponding to the (j−a)th scan stage as the carry signal when the (j−a)th scan stage is one of the some first scan stages.
