Abstract
A gate drive circuit is disclosed. The gate drive circuit includes shift register units connected with gate lines. The gate drive circuit also includes clock signal lines to provide clock signals. A trigger signal terminal of the first shift register unit is connected with a first initial trigger signal line, and a trigger signal terminal of the p-th shift register unit is connected with an output terminal of the (p−1)-th shift register unit. An end signal terminal of the r-th shift register unit is connected with an output terminal of the (r+2)-th shift register unit, low level signal terminals are connected with a first low level signal line, and reset signal terminals are connected with a reset signal line. In addition, forward scan signal terminals are connected with a first scan signal line, and backward scan signal terminals are connected with a second scan signal line.
