GATE DRIVING CIRCUIT AND IMAGE DISPLAY SYSTEM

摘要

A gate driving circuit includes a plurality of shift registers connected in series. The shift registers include a plurality of output shift registers and X groups of dummy shift registers. The output shift registers output the gate driving signal to a plurality of gate driving lines of the pixel matrix in sequence. At least one of the X groups of dummy shift registers has J dummy shift registers and is connected between two adjacent output shift registers in the output shift registers, wherein at least one driving signal generated by the group of dummy shift registers is partially overlapped with the gate driving signal generated by the two adjacent output shift registers in a frame, wherein the X groups of dummy shift registers are not connected to the gate driving lines, and X and J are integers greater than zero.
