Abstract: A method of driving a scan circuit includes providing N number of first clock signals time-sequentially to (k*N) number of stages of the scan circuit, respectively. The (k*N) number of stages includes M number of groups. A respective group of the M number of groups includes one or more stages of the scan circuit. A respective first clock signal of the N number of first clock signals includes a first level component and a second level component. With respect to N number of data enabling signals, a difference between a starting point of a first level component of an n-th first clock signal and a starting point of an n-th data enabling signal of the N number of data enabling signals is equal to tm1. Values of tm1 for first clock signals provided to different groups of the M number of groups are different.
