Abstract:
A scan driver includes: a plurality of stages, each stage including: a logic circuit configured to transfer an input signal to a first node in response to a first clock signal, and to bootstrap the first node in response to a second clock signal; a carry output circuit configured to output the second clock signal as a carry signal that is provided as the input signal for a next stage in response to a voltage of the bootstrapped first node; and a masking controller configured to receive a masking signal and the carry signal, and to output the masking signal as a scan signal provided to a pixel row corresponding to the each stage in response to the carry signal.
