Document Type and Number:
WIPO Patent Application WO/2017/124731
Kind Code:
A1
Abstract:
The present invention relates to the field of display, and discloses a shift register, drive method thereof, GOA circuit, and display device to solve non-uniformity of display caused by an insufficient gate signal output in a large-sized GOA display product. The shift register (10) for use in a GOA circuit comprises: a pull-up node, a capacitor, and an output control module (11). The output control module (11) comprises: a first thin film transistor, wherein a control end of the first thin film transistor and a first end of the capacitor are connected to the pull-up node, a first clock signal is inputted at a first end of the first thin film transistor, and a second end of the first thin film transistor is connected to a second end of the capacitor; and a pre-charge module (12) used to receive a signal from the pull-up node, and output, before the shift register (10) outputs an effective voltage, to an output end of the shift register (10) a pre-charge voltage having the same polarity as the effective voltage.
