Abstract
Provided is a timing controller. The timing controller includes: M signal output terminals, wherein the M signal output terminals are respectively connected to M signal input terminals corresponding to M source driver chips; the timing controller includes a controller, a timing transmission circuit, and a pull-down circuit. 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, 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.
