Claim:
1. A shift register group, the shift register group comprising a plurality of series-coupled shift registers each being configured to provide an output signal, each one of the plurality of shift registers comprising: a first output terminal, configured to provide the output signal; a first output terminal control circuit, electrically coupled to the first output terminal and configured to receive a clock signal and determine whether to transmit the clock signal to the first output terminal or not according to a voltage at a driving node; a first driving node control circuit, electrically coupled to the driving node and configured to receive a first control signal and determine whether to transmit the first control signal to the driving node or not according to a second control signal; and a second driving node control circuit, electrically coupled to the driving node and configured to receive a third control signal and determine whether to transmit the third control signal to the driving node or not according to a fourth control signal, wherein the third control signal of a first sift register of the plurality of shift registers is the output signal provided by the shift register N stages after the first shift register, and the fourth control signal of the first sift register is the voltage at the driving node of the shift register 2N stages after the first shift register, wherein N is a natural number, wherein the plurality of shift registers are divided into a plurality of groups each consisting of two shift registers, the two shift registers in the same group are corresponding to the same clock signal, an enable period of the clock signal corresponding to a specific group comprising the first shift register and an enable period of the clock signal corresponding to a group last the specific group partially overlap, and the enable period of the clock signal corresponding to the group last the specific group and an enable period of the clock signal corresponding to a group next the specific group do not overlap.
