  • Patent number: 11984084
    Abstract: The disclosure relates to a shift register, a driving method thereof, a gate drive circuit, and a display device. An output pulse width can be reduced by 1/(n+1) to (n?1)/(n+1) clock cycle by setting a pulse width modulation module (104), where n is the number of clock signal terminals in one-to-one correspondence with the enable signal terminals, and the pulse width reduced by 1/(n+1) to (n?1)/(n+1) clock cycle needs to be output several times under the condition that the light emitting duration of pixels is unchanged. In this way, the refresh rate is increased, and thus the flicker phenomenon in the process of low gray-scale brightness adjustment is less detectable to the human eyes.
