Abstract
A shift register which allows narrower framing of a display screen includes cascade-connected shift register modules. Each shift register module is electrically coupled to first and second scan lines and outputs scanning signals to the first and the second scan lines in a time-division manner in response to first to fourth clock signals. Each shift register module includes an initial circuit, a reset circuit, a first output circuit, and a second output circuit. The initial circuit receives a trigger signal for activating the shift register module. The initial circuit controls the first output circuit to output a signal to the first scan line based on the first clock signal and controls the second output circuit to output a signal to the second scan line according to the second clock signal.
