Abstract
Drive circuit and method, scanning circuit and method, and display device are provided. The drive circuit includes a shift register sub-circuit and an output sub-circuit. The shift register sub-circuit outputs a first level from a first level terminal based on an effective level of a second control clock signal, outputs an ineffective level of a first control clock signal based on effective levels of a third control clock signal and a turn-on control signal and subsequently outputs an effective level of the first control clock signal. The output sub-circuit outputs the first level based on the effective level of the first control clock signal output by the shift register sub-circuit, and outputs a second level based on an effective level of an interval clock signal.
