Abstract
A shift register, a method and a system for operating the shift register are provided. The shift register includes: an input circuit adapted to output a first voltage signal in response to an input signal; a trigger circuit adapted to generate a second voltage signal based on a first reference voltage and a second reference voltage, in response to the first voltage signal; and generate a third voltage signal, different than the second voltage signal, based on the first reference voltage and the second reference voltage, in response to the first voltage signal; and an output circuit adapted to output a scanning signal based on the second voltage signal and the third voltage signal. The voltages of the second voltage signal and the third voltage signal depend on a voltage dividing value of the trigger circuit, and the voltage dividing value of the trigger circuit is based on the first reference voltage and the second reference voltage.
