Abstract
The present disclosure provides a signal generation circuit, a signal generation method, a signal generation module and a display device. The signal generating circuit includes an input terminal, a signal output terminal, a transmission control circuit, a first output circuit, and an output control circuit; the output control circuit is electrically connected to a first output control terminal, a second output control terminal, a second voltage terminal, the signal writing-in terminal, the signal output terminal and the first voltage terminal, configured to control to connect the signal writing-in terminal and the second voltage terminal under the control of a second output control signal provided by the second output control terminal, and control to connect the signal output terminal and the first voltage terminal under the control of a first output control signal provided by the first output control terminal. The present disclosure expands an adjustment range of frequency of a PWM signal.
