GATE DRIVE CIRCUIT, CONTROL METHOD THEREFOR, AND DISPLAY DEVICE

WIPO Patent Application WO/2021/109245

A1

A gate drive circuit, a control method, and a display device. The gate drive circuit comprises a primary pull-up drive unit (1), a primary pull-up unit (2), a primary pull-down drive unit (3), a primary pull-down unit (4), a secondary pull-up drive unit (5), a secondary pull-up unit (6), and a secondary pull-down unit (7). The primary pull-up drive unit (1) is separately connected to the primary pull-up unit (2), the primary pull-down drive unit (3), and the primary pull-down unit (4). The primary pull-up unit (2) is further separately connected to the primary pull-down unit (4) and the secondary pull-up drive unit (5). The primary pull-down drive unit (3) is further connected to the primary pull-down unit (4). The secondary pull-up drive unit (5) is further separately connected to the secondary pull-up unit (6) and the secondary pull-down unit (7). The secondary pull-up unit (6) is further connected to the secondary pull-down unit (7). By making a clock signal of the other stage low and turn off pull-down transistors during one-stage output, the interlocking of a circuit during output is realized, and the effect of triggering a trigger signal STU to generate two-stage output signals is achieved.
