Shutdown discharge control circuit, system and method and display equipment

The embodiment of the invention provides a shutdown discharge control circuit, system and method and display equipment, and is applied to the technical field of display. In the circuit, the input end of a frequency reduction module and the first input end of a frequency switching module are connected with the first output end of an oscillator; the second input end of the frequency switching module is connected with the output end of the frequency reduction module; the output end of the frequency switching module is connected with the level translator circuit; the frequency reduction module performs frequency reduction on the input electric signal and outputs the electric signal after frequency reduction; and after receiving the discharge trigger signal, the frequency switching module outputs an electric signal after frequency reduction. By applying the circuit provided by the embodiment of the invention, the electric signal can be subjected to frequency reduction through the frequency reduction module, and th
