摘要:
A gate driving circuit includes a first clock generator to output n output control clock pulses having different phases; a second clock generator to create m*n output clock pulses having different phases and partially overlapped with one another in high periods thereof, to arrange the m*n output clock pulses in sequence of phase, to bind the m*n output clock pulses arranged in sequence of phase in units of n to generate m groups, each of which has n output clock pulses, and to output the m*n output clock pulses so that a rising edge of an output clock pulse having a k-th sequence of phase included in each group is located in a high period of an output control clock pulse having a k-th sequence of phase among the n output control clock pulses; and a shift register sequentially outputting a plurality of scan pulses.
