Drive control method applicable to timing controller, and drive circuit

A drive control method, applicable to a timing controller, the method comprising:

• controlling M signal output terminals of the timing controller to be connected to ground in a first phase, such that M source driver chips enter a low power consumption mode in the case that M source driver chips detect that signal input terminals are connected to ground, wherein the first phase indicates a phase in which the M source driver chips are expected to enter the low power consumption mode;
• and
• controlling the M signal output terminals not to be connected to ground in a second phase, such that the M source driver chips enter a low power consumption wakeup mode in the case that the M source driver chips detect that the signal input terminals are not connected to ground, wherein the second phase indicates a phase in which the M source driver chips are expected to enter the low power consumption wakeup mode;
• wherein a total duration of the first phase and the second phase is fixed, and a duration of the second phase is less than a reference duration.

A drive circuit, comprising a timing controller and M source driver chips, wherein the timing controller comprises:

• M signal output terminals, wherein the M signal output terminals are respectively connected to M signal input terminals corresponding to the M source driver chips, M being a positive integer;
• and
• a controller, a timing transmission circuit, and a pull-down circuit, wherein a first output terminal of the controller is connected to an input terminal of the timing transmission circuit, an output terminal of the timing transmission circuit is connected to the M signal output terminals, a second output terminal of the controller is connected to a control terminal of the pull-down circuit, a first connection terminal of the pull-down circuit is connected to the M signal output terminals, and a second connection terminal of the pull-down circuit is connected to ground;
• wherein the controller is configured to control the timing transmission circuit and the pull-down circuit, such that the M signal output terminals are connected to ground in a first phase, wherein the M source driver chips are in a low power consumption mode in the case that the M signal input terminals are connected to ground, and the first phase indicates a phase in which the M source driver chips are expected to enter the low power consumption mode.
